composite figure pls help
Answer:
Step-by-step explanation:
divide the figure into 2 rectangle the one on top and bottom. Th one on top's dimensions would be length = 9 width = 3.
the bottom rectangles dimensions would be length = 5 (because 9-4) and width would be 3 (because 6-3)
so top rectangle : 9*3 = 27
bottom rectangle: 5*3 = 15
27+15 = 42
Answer:
[tex]A_{total} = 42\ cm^2[/tex]
Step-by-step explanation:
Step 1: Determine the area of the left rectangle
[tex]A = l * w[/tex]
[tex]A = 6\ cm * (9\ cm - 4\ cm)[/tex]
[tex]A = 6\ cm * 5\ cm[/tex]
[tex]A = 30\ cm^2[/tex]
Step 2: Determine the area of the right rectangle
[tex]A = l * w[/tex]
[tex]A = 4\ cm * 3\ cm[/tex]
[tex]A = 12\ cm^2[/tex]
Step 3: Determine the total area
[tex]A_{total} = 30\ cm^2 + 12\ cm^2[/tex]
[tex]A_{total} = 42\ cm^2[/tex]
Answer: [tex]A_{total} = 42\ cm^2[/tex]
Manuel is packing smaller boxes inside a large box. The
smaller boxes are cube-shaped and measure 6 inches
along each edge. The large box is cube-shaped and
measures 24 inches along each edge. How many
smaller boxes can Manuel fit in the large box?
The number of the smaller cube-shaped boxes that Manuel can fit into the large cube-shaped box is: 64.
What is the Volume of a Cube?Volume of a cube = a³, where a is the edge length of the cube.
Volume of the smaller cube-shaped boxes = a³ = 6³ = 216 in.³
Volume of the larger cube-shaped box = a³ = 24³ = 13,824 in.³
Number of the smaller boxes that will fit into the large box = 13,824/216 = 64 smaller cube-shaped boxes.

10/3
as a division
expression and as a mixed number?
Answer:
Division: 10 ÷ 3
Mixed Number 3 and 1/3
Answer:
10/3 in a mixed fraction is 3 1/3.
Let us convert the improper fraction to a mixed number.
Step-by-step explanation:
Converting an improper fraction to a mixed number involves dividing the numerator by the denominator.
And we keep the quotient part as separate
The quotient of 10 divided by 3 is 3
While the remainder of 10 divided by 3 is 1
The mixed number is written as Quotient (Remainder/Divisor), i.e., 3 1/3
Thus, 10/3 in a mixed fraction is 3 1/3.

Probability can be expressed as either a decimal, a percentage or a fraction. But no
matter what form it takes, it means the same thing, 1/10, 0.1 and 10% are all different ways
of expressing the same probability.
An easy way to convert a percentage to a fraction is to put the number of the percentage
over 100 and then simplify, for example, 75% is the same as 75/100, or 3/4 The first two
places after a decimal point are the same as a percentage: 0.15 is equal to 15%, and 0.3 is
equal to 30%

Which probability is equal to 25%?
A
5/100
B
1/4
С
25/1
D
4/5
Answer:
B. 1/4
Step-by-step explanation:
The easiest way to find the answer here is to (if you have one) use a calculator to divide each fraction.
When divided 1/4, you get .25, and as the explanation says, "The first two places after a decimal point are the same as a percentage: 0.15 is equal to 15%, and 0.3 is equal to 30%."
So, moving the decimal to the right two times will give you your probability of 25%.

18π
Step-by-step explanation:
so first you need to find the area of both semi- circles. To do this you will use the formula 1/2πr^2 since it is half the area of a circle.
So for the smaller semi circle you do 1/2×π×8^2 to get 32πcm^2.
Now for the large semicircle you do 1/2×π×10^2 to get 50πcm^3.
Now you take 50π from 32π to get just the area of the shaded region.
This is 18π or 56.55cm^2

Approximately 40% of the scores are greater than which score?
370
387
413
430
Using the normal distribution, it is found that approximately 40% of the scores are greater than 413.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, we have that the mean and the standard deviation of the scores are given by:
[tex]\mu = 400, \sigma = 50[/tex]
Approximately 40% of the scores are greater than the 60th percentile, which is X when Z = 0.253.
Then:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.253 = \frac{X - 400}{50}[/tex]
X - 400 = 50(0.253)
X = 412.65.
Rounding up, approximately 40% of the scores are greater than 413.

5(x-3)^2 - 20 = 0 we can find the value of x by sorting out the number one by one and leaving x alone on one side:
5(x-3)^2 = 20 (transfering 20 to the right side of the equation)(x-3)^2 = 20/5 and that is equal to 4, now find the root for both sides x-3 = 2 add 3 to both sidesx = 5Alejandro surveyed his classmates to determine who has ever gone surfing and who has ever gone snowboarding. let a be the event that the person has gone surfing, and let b be the event that the person has gone snowboarding. a 4-column table has 3 rows. the first column has entries has surfed, never surfed, total. the second column is labeled has snowboarded with entries 36, 12, 48. the third column is labeled never snowboarded with entries 189, 63, 252. the fourth column is labeled total with entries 225, 75, 300. which statement is true about whether a and b are independent events? a and b are independent events because p(a∣b) = p(a) = 0.16. a and b are independent events because p(a∣b) = p(a) = 0.75. a and b are not independent events because p(a∣b) = 0.16 and p(a) = 0.75. a and b are not independent events because p(a∣b) = 0.75 and p(a) = 0.16.
Using the concept of independent events, it is found that the correct statement is:
a and b are independent events because p(a∣b) = p(a) = 0.75.
When are two events independent?
Two events, A and B, are independent if:
[tex]P(A \cap B) = P(A)P(B)[/tex]
In this problem, the events are:
Event A: Surfing.Event B: Snowboarding.In this problem, out of 300 students, 225 have surfed, hence:
[tex]P(A) = \frac{225}{300} = 0.75[/tex]
48 have gone snowboarding, hence:
[tex]P(B) = \frac{48}{300} = 0.16[/tex]
36 have done both, hence:
[tex]P(A \cap B) = \frac{36}{300} = 0.12[/tex]
The multiplication is:
P(A)P(B) = 0.75 x 0.16 = 0.12.
That is, the probability of A given B is P(A|B) = P(A) = 0.75, hence they are independent.

1. A toy company finds there is a linear relationship between p, the price they charge for a playground ball, and n(p), the number of balls they sell during a year. When they charge $3, they sell 8000 balls during the year. However, sales drop to 5200 balls when they charge $5 each.
a. Write an equation for the linear function n(p).
b. Use your function to determine the number of balls they can expect to sell during the year if they charge $6.50 for a ball.
Answer:
Below in bold.
Step-by-step explanation:
The general form of a linear function can be written as:
n(p) = kp + C where k and C are constants.
So substituting the given data:
8000 = 3k + C
5200 = 5k + C Subtract
2800 = -2k
k = -1400
and C = 8000 - 3(-1400) = 12200
a. So the equations is:
n(p) = -1400p + 12200
b.
For a charge p of $6.50;
n(p) = -1400*6.5 + 12200
= 3100 balls.

Step-by-step explanation:
1)180°=72°+(3y)°
=>(3y)°=180°-72°
=>(3y)°=108°
=>3y=108
=>y=36
2)(x)°=(3y)°=>x=108
3)(3z+18)°=108°=>3z+18=108=>3z=90=>z=30
Answer:
x = 108
y = 36
z = 30
Step-by-step explanation:
(x)° + 72° = 180° (interior angles on the same side of transversal)
-> (x)° = 180 - 72°
-> (x)° = 108°
-> x = 108
(3y)° = (x)° (corresponding angles)
-> 3y = x
-> 3y = 108
-> y = 108/3
-> y = 36
(3z + 18)° = (x)° (corresponding angles)
-> 3z + 18 = x
-> 3z + 18 = 108 - 18
-> 3z = 108 - 18
-> 3z = 90
-> z = 90/3
-> z = 30
