Mrs. Ruiz bought 5 bags of balloons for a party. Each bag contained 70 balloons. Andy said Mrs. Ruiz bought a total of 75 balloons. Andy is incorrect. What error did Andy make when calculating the total number of balloons? And What is the total number of balloons Mrs. Ruiz bought?
Answer:
Andy made the error of adding the values of the bags and the ballons, when instead they should be multiplied. The total number of baloons Mrs. Ruiz bought is 350 because 70*5 is 350. You multiple because there are five bags and in each of the five bags, there are 70 balloons.

In the month of November, a dance troupe had 300 members.
In December, there was a 20% decrease in the members.
In January, there was a 20% increase from the month before.
How many members were there in January?
Answer:
432 members
Step-by-step explanation:
300*1.2=360,360x1.2=432
300 represents the starting number, we multiply it by 1.2 because 1.2 means 20%, when we multiply, we get 360, that means that there are 260 members in december, so then we mutiply 360*1.2 in order to find out how many members there are in january, 360*1.2=432
A weight attached to a spring is at its lowest point, 9 inches below equilibrium, at time t = 0 seconds. when the weight it released, it oscillates and returns to its original position at t = 3 seconds. which of the following equations models the distance, d, of the weight from its equilibrium after t seconds? d = negative 9 cosine (startfraction pi over 3 endfraction t) d = negative 9 cosine (startfraction 2 pi over 3 endfraction t) d = negative 3 cosine (startfraction pi over 9 endfraction t) d = negative 3 cosine (startfraction 2 pi over 9 endfraction t)
The equation which models the distance (d) of the weight from its equilibrium after time (t) is equal to d = -9cos(2π/3)t.
What is the period of a cosine function?The period of a cosine function simply means the total length (distance) of the interval of values on the x-axis over which a graph lies and it's repeated.
Since the weight attached is at its lowest point at time (t = 0), therefore, the amplitude of equation will be negative nine (-9)
For the angular velocity at time period (t = 3s), we have:
ω = 2π/T
ω = 2π/3
Mathematically, the standard equation of a cosine function is given by:
y = Acos(ω)t
Substituting the given parameters into the formula, we have;
d = -9cos(2π/3)t.

Flora wants to create a scale drawing of
the Empire State Building on an 8 inch
by 11 inch piece of paper. She wants the
drawing to be as large as possible. Which
shows the scale she should use?
Length- 1,792
With- 195
Answer:
The scale drawing is 1 centimeter to 50 meters ⇒ answer E
Step-By-Step Explanation:
* Lets explain how to solve the problem
- The height of the empire state building is about 1450 feet long and
400 feet wide
- Andre wants to make a scale drawing of the front view of it on an
8 1/2 inches by 11 inches piece of paper
- We need to select one of these scales that we think is the most
appropriate for the scale drawing
A. 1 inch to 1 foot
B. 1 inch to 100 feet
C. 1 inch to 1 mile
D. 1 centimeter to 1 meter
E. 1 centimeter to 50 meters
F. 1 centimeter to 1 kilometer
- For scale A , B , and D the scaled image will not fit the page
- For scale C and F the drawing will be very small because 1 mile
is 5280 feet and 1 kilometer is 3280.84 feet
- E is most appropriate because 1 meter is 3.28084 feet, then the
height of the empire state is 442 m dividing by 50 m gives about
8.8 cm and the height of the paper is 11 inches which is about 28 cm
and the width of the empire state is about 122 m dividing by 50 m
gives about 2.5 cm and the width of the paper is 8 1/2 inches which
is about 22 cm then the drawing will be appropriate for drawing
∴ The scale drawing is 1 centimeter to 50 meters

Craig is learning to identify local birds with a Field Guide to Forest Birds deck of cards. He
randomly selects one card from the deck, puts it back in the deck, and selects another card.
He repeats this several times and gets 4 hummingbirds, 3 falcons, 1 woodpecker, 4 owls, 3
loons, and 2 eagles.
Based on the data, what is the probability that the next card Craig selects will be a falcon
card?
Write your answer as a fraction or whole number.
The probability helps us to know the chances of an event occurring. The probability that the next card Craig selects will be a falcon
card is 3/17.
What is Probability?The probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given that Craig gets 4 hummingbirds, 3 falcons, 1 woodpecker, 4 owls, 3
loons, and 2 eagles. Therefore, a total of 17 possible outcomes. Now, since the number of outcomes which are falcon is 3. Therefore, the probability of the next card being a falcon can be written as,
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
[tex]\rm Probability = \dfrac{\text{Number of falcon cards}}{\text{Total number of possible outcomes }} = \dfrac{3}{17}[/tex]
Hence, the probability that the next card Craig selects will be a falcon
card is 3/17.

What is the slope of the line passing through the points (0, 4) and (6, 13)
Answer:
The slope is [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Hi there!
We are given the points (0, 4) and (6, 13)
We want to find the slope of the line containing these two points
Slope (m) is the steepness of the line. When calculating from two points, you use the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
Although we have what we need to find the slope, let's label the values of the points to avoid confusion and mistakes.
[tex]x_1=0\\y_1=4\\x_2=6\\y_2=13[/tex]
Substitute these values into the equation
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{13-4}{6-0}[/tex]
Subtract
m=[tex]\frac{9}{6}[/tex]
Simplify
m=[tex]\frac{3}{2}[/tex]
The slope of the line is 3/2
Hope this helps!

Every 10 years in December, the population of a certain town is recorded. In 1997,
the town had a population of 3,200 people. From 1997 to 2007, the population
increased by 15%. From 2007 to 2017, the population decreased by 3%. What was
the population in 2017?
Answer:
3570
Step-by-step explanation:
We use percentage formula here:
Beginning Amount * Percentage = Final Amount
Plug in the values
3200 * 15/100 = Final
480= Final
Now we have 480 ppl growth from 97 to 07, so we have 3680 people
3680 * 3/100= Final
110.4= Final
110=Final
(Rounded)
Now that we decreased, we subtract 3680-110 and get the final population of 3570
We are given two metrics to work with: 10 years of time, and population change. The base is 3200 people at 1997. Ten years later, 3200 is increased to 3680 people, presumably due to living conditions improving. Another ten years later, the town's situation is stagnating. The population decreases somewhat, dropping down to 3569.6. This is because someone lost an arm and a leg, decreasing their person status to 60%.
Line s has an equation of y=1/3-X-5. Line t is perpendicular to line s and passes through (-2, 9). What is the equation of line t?
Write the equation in slope-intercept form. Write the numbers in
the equation as simplified proper fractions, improper fractions, or
integers.
Answer:
y = 3x + 15
Step-by-step explanation:
1. Find the reciprocal of the slope and change signs: -3
2. y = 3x + b
3. Plug in x and y --> b = 15
4. Make your equation using y = mx + b: y = 3x + 15
The equation of the perpendicular line 't' will be equal to y = -3x + 3.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that line, s has an equation of y=1/3-X-5. Line t is perpendicular to line 's' and passes through (-2, 9).
The equation of the line will be calculated as,
For the perpendicular line, the slope is reciprocal with a negative sign,
m = -3
The equation of the line will be written as,
y = mx + c
y = -3x + c
9 = ( -3 x - 2) +c
c = 9 - 6
c = 3
The equation is,
y = mx + c
y = -3x + 3
Therefore, the equation of the perpendicular line 't' will be equal to y = -3x + 3.

[tex]A= 5\ ft * 7\ ft = 35\ ft^2[/tex]
[tex]A= 3\ ft * 7\ ft = 21\ ft^2[/tex]
Area of the top and bottom triangles
[tex]A= \frac{h\ *\ b}{2} = \frac{3\ ft\ *\ 4\ ft}{2} = \frac{12\ ft^2}{2} = 6\ ft^2 = 2(6\ ft^2) = 12\ ft^2[/tex]
Total Area
[tex]28\ ft^2 + 35\ ft^2 + 21\ ft^2 + 12\ ft^2[/tex]
[tex]96\ ft^2[/tex]
Answer: A = 3 ft, B = 7 ft, C = 4 ft, D = 5 ft, Surface Area = 96 ft^2
Answer:
Surface Area = 96 ft^2
Step-by-step explanation:
A = 3 ft.
B = 7 ft.
C = 4 ft.
D = 5 ft.
Surface Area:
Triangle: Area = 1/2 * Base * Height
Top Triangle: Area = 1/2 * 4 * 3 = 1/2 * 12 = 6 ft^2
Bottom Triangle: Area = 6 ft^2
Rectangle: Area = Length * Width
Left Rectangle: Area = 7 * 4 = 28 ft^2
Mid Rectangle: Area = 7 * 5 = 35 ft^2
Right Rectangle: Area = 7 * 3 = 21 ft^2
Surface Area = TopTri + BotTri + LeftRect + MidRect + RightRect
Surface Area = 6 + 6 + 28 + 35 + 21 = 96 ft^2
