A pair of pants that regularly costs $55 are on sale for 35% off the regular price. What is the sale price of the pants?
Answer:
$35.75
Step-by-step explanation:
100-35=65
.65 x 55 = 35.75
Answer:
$35.75
Step-by-step explanation:

a room has a rectangular floor that measures 28 feet by 14 feet and a flat 9-foot ceiling. what is the area of the floor and how much air does the room hold?
Answer:
Step-by-step explanation:
write the equation of the line from the given information (-2,4) & (-3,5)
Step 1: Find the slope
Slope Formula = (y2 - y1) / (x2 - x1)
Point 1 = (-2, 4)
Point 2 = (-3, 5)
slope = (5 - 4) / (-3 - - 2) = (5 - 4) / (-3 + 2) = (1) / (-1) = -1
Step 2: Find the y-intercept
To find the y-intercept, we will take one of the given points as well as the slope and plug them into slope-intercept form. Then, we will solve for b.
Slope-Intercept Form: y = mx + b
Point = (-2, 4)
Slope = -1
4 = -1(2) + b
4 = -2 + b
b = 6
Step 3: Put it all together
Now that we have the slope and the y-intercept, all that's left to do is plug it into slope-intercept form.
Slope-Intercept Form: y = mx + b
Slope = -1
Y-Intercept = 6
y = -x + 6
Hope this helps!! :)
What is the slope of (-6,-3) and (-2,-8)
Answer:
-5/4
Step-by-step explanation:
.......................
The question gives us two points, (-6,-3) and (-2,-8), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (-8 - (- 3)) ÷ (-2 - (-6))
= - ⁵/₄
Checking my answer:
Finding the Equation
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - (-3) = - ⁵/₄(x - (-6))
y + 3 = - ⁵/₄ (x + 6)

If six angles of a heptagon have measures of 122, 153, 168, 105, 162, and 87, what is the measure of the seventh angle?
Answer:
he seventh angles measure is 103
Step-by-step explanation:
Interior angles = (number of side in the polygon - 2) times 180.
So Heptagon interior angles = (7-2)(180) = 900
To find the missing angles add all the given angles together (122, 153, 168, 105, 162, and 87) = 797.
Now The measure of the seventh angles = total angles measure - the six given angles,
The seventh angles measure is 103
900 - 797 = 103

Using diagonals from a common vertex, how many triangles could be formed from a hexagon?
A factory makes 84 toys robots in a day after they purchase new equipment now they make 205 robots a day
Based on the given information the percent gain is 144%.
Initial production rate = 84 toy robots per day
Present production rate = 205 robots per day
Using this formula
Percent gain= Increase in production rate /Initial production rate× 100
Where:
Increase in production rate = 205 - 84 =121
Initial production rate = 84 toy robots per day
Let plug in the formula
Percent gain=121/84×100
Percent gain=144%
Inconclusion the percent gain is 144%.

what is [tex]−3.64⋅|5.3|−1.5^3[/tex]
Answer:
- 22.667
Step-by-step explanation:
1.5^3 = 1.5 x 1.5 x 1.5 = 3.375
- 3.64 ⋅ | 5.3 | - 1.5^3
= ( - 3.64 ⋅ | 5.3 | ) - 1.5^3
= ( - 3.64 ⋅ 5.3 ) - 1.5^3
= ( - 3.64 x 5.3 ) - 1.5^3
= - 19.292 - 3.375
= - 22.667

How do you compare exponential functions??
I really don't understand, also giving brainliest!!
Answer:
You compare it by this
Step-by-step explanation:
Linear functions are graphed as straight lines while exponential functions are curved. Linear functions are typically in the form y = mx + b, which is used to discover the slope, or simply the change in y divided by the change in x, while exponential functions are typically in the form y = (1 + r) x.

give the slope perpendicular to the equation 2x-y=5
Answer:
- [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x - y = 5 ( subtract 2x from both sides )
- y = - 2x + 5 ( multiply through by - 1 )
y = 2x - 5 ← in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex]
Mary got a rectangular box. If the perimeter is 82cm and the length is 23cm, what is the
width of the box?
Answer:
w = 18cm
Step-by-step explanation:
Using the formula
P = 2 (l + w)
Solving for w
w = P
2﹣l = 82
2﹣23 = 18cm
The mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.9 feet. Let X be the height of a randomly selected adult giraffe. Round all answers to 4 decimal places where possible.
c. What is the Z-score for a giraffe that is 18.5 foot tall?
d. What is the probability that a randomly selected giraffe will be shorter than 17.5 feet tall?
e. What is the probability that a randomly selected giraffe will be between 16.7 and 17.2 feet tall?
f. The 70th percentile for the height of giraffes is ___ ft.
Answer:
Median =17
Step-by-step explanation:
Given that the mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.9 feet. Let X be the height of a randomly selected adult giraffe. X is a random variable.
a) X is N(17, 0.9)
b) Median giraffe height = 17 ft since in normal distribution mean = median
c) When x = 18.5, Z = 18.5-17/0.9 = Z= 0.1667
d) P( x < 18) = P( Z < 56)
= 0. 2877
e) P(16.9 < x < 17.9) = P(-0.11 < z < 1) = .0.438 + 0.3413
= 0.3851
f) 75th percentile for z is 0.675
x = 17.9 + 0.9 (0.675)
= 18.5075
