find the measure of each angle if C D
Answer:
1=72 , 2=108 , 3= 72 , 4=108
Step-by-step explanation:
c parallel to d means that 108 and 1 are adjacent angles , sum 180
therefore ang 1 = 180-108=72
2=108, corresponding angles,
same as above for 3, angle 3= 180-108 =72
2 and 4 are vertically opposite and are equal.
HELP DUE IN 15 MINS!
Y=??
Answer:
y = 70 degree's
Step-by-step explanation:
180 is a straight line therefore the equation would read ...
180 = 110 + y
subtract 110 from both sides ...
70 = y
Answer:
y = 70
Step-by-step explanation:
This is a supplementary angle so:
y + 110 = 180
y = 180 - 110
y = 70
Henry had $22 and Ben had $17. Henry spent twice as much as Ben and was left with half as much as Ben. The amount of money that Ben spent is $____.
Answer:
Ben spent 9$
Step-by-step explanation:
Ben=x Henry=2x
17-x= 2(22-2x)
17-x=44-4x
-x+4x=44-17
3x=27
x=27/3
x=9 $ Ben spent

The equation of the scatter plot trend line is y = -1700x + 32000 where y is the value of the car in dollars and x is the age of cars in years. Use the trend line equation to predict the value of a car after 7 years.
Answer:
20100
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Given equation
y = -1700x + 32000
Where x is the age of car and y is the value of the car.
Then value after 7 years can be calculated as follows,
y = -1700 (7) + 32000
y = -11900 + 32000
y = 20,100
So, the value of car after 7 years will be 20100.

Answer:
12.71in
step explanation:
The Length of an arc given is expressed as;
A = theta/360 * 2πr
10 = 45/360 * 2 * 3.14r
10 = 1/8 * 6.28r
Cross multiply
10 * 8 = 6.28r
80 = 6.28r
r = 80/6.28
r = 12.74in
Hence the radius is 12.71in
what's the area of this shape
Answer:
L x W x H
Step-by-step explanation:
if my calculations are correct the length is 2 the width is 3 and the height is 3
Therefore the answer is (2 x 3) = 6 x3
So the answer is 18.
Hope it helps, if it is incorrect than i am extremely sorry, wish you the best of luck and have a great day/midday/evening. BYYEEEEEEE
A game decreased in price by 1/6
After the reduction it was priced at £75.
What was the original price of the game?
Answer:
Step-by-step explanation:
original price is x
Then the decreased price will be ' x - x/6'
= 5x/6
5x/6= 75
x= (75×6)/5
x= 90
original price = £90
Answer:
£90
Step-by-step explanation:
Since it was decreased by 1/6, it is 5/6 of the original price.
divide 75 by 5 to get 15.
15 is 1/6 of the price.
To get the full price, (6/6) multiply 15x6 and you will get 90.
When Charlotte installed a fence along the 200 foot perimeter of her rectangular backyard, she left an opening for a gate. In the diagram below, she used x to represent the length, in feet, of the gate. What is the value of x
Answer:
x = 10
Step-by-step explanation:
P = 2(60 + x) + 2(30) = 200
= 120 + 2x + 60 = 200
2x + 180 = 200
2x = 20
x = 10
A simple random sample from a population with a normal distribution of 103 body temperatures has x = 98.30°F and s = 0.61°F. Construct a 95% confidence interval estimate of the standard deviation of body temperature of all healthy humans.
Answer:
(98.2884 ; 98.3116)
Step-by-step explanation:
Given :
x = 98.30°F and s = 0.61°F
Sample size. n = 103
Zcritical at 95% = 1.96
Using the confidence interval relation :
x ± margin of error
Margin of Error :
Zcritical * s/√n
1.96 * 0.61/√103 = 0.0116
Lower boundary = (98.30 - 0.0116) = 98.2884
Upper boundary = (98.30 + 0.0116) = 98.3116
(98.2884 ; 98.3116)

A circular patio has a radius of 4 yards. The patio is expanded so that the radius increases by 2 yards.
1) What is the area of the original patio? (blank)
Square yards
2) What is the area of the new patio? (blank)(
Square yards
3) By how many square yards does the area of the patio increase? (blank)
Square yards
Answer:
50.29 yards^2
113.14 yards^2
62.85 yards^2
Step-by-step explanation:
Area of a circle = πr²
π = pi = 22/7
r = radius
original area
(22/7) x 4² = 50.29 yards²
New area
radius = 4 + 2 = 6
(22/7) x 6² = 113.14 yards²
Increase in the area of the patio = 113.14 yards² - 50.29 yards²=62.85
One fourth the sum of x and ten is identical to x minus 4."
Answer and Step-by-step explanation:
We are given the word format of an equation.
Let's right it out in numerical form.
[tex]\frac{1}{4} (x + 10) = x - 4[/tex]
The first part says One fourth the sum of x and 10
The sum of x and 10 would be shown as x + 10, and one fourth of that means that [tex]\frac{1}{4}[/tex] is multiplying (x + 10).
In this case, identical would mean equal to.
So, [tex]\frac{1}{4}[/tex](x + 10) would be = to something.
It says that it is identical to x minus 4 (x - 4).
[tex]\frac{1}{4} (x + 10) = x - 4[/tex] is the equation.

Wanderella Skimpole has a dish that is a right rectangular prism. Its width is 10 inches, and its length is 16 inches. If the volume of the dish is 1,120 in3 , what must be its height?
Given:
Width of a rectangular prism = 10 inches
Length of the rectangular prism = 16 inches
Volume of the rectangular prism = 1,120 cubic inches
To find:
The height of the rectangular prism.
Solution:
We know that the volume of a rectangular prism is:
[tex]V=l\times w\times h[/tex]
Where, l is length, w is width and h is height.
Putting [tex]l=10,w=16,V=1120[/tex] in the above formula, we get
[tex]1120=10\times 16\times h[/tex]
[tex]1120=160\times h[/tex]
[tex]\dfrac{1120}{160}=h[/tex]
[tex]7=h[/tex]
Therefore, the height of the rectangular prism is 7 inches.

Find the 11th term of the geometric sequence 6, -18, 54, ...
Answer:
354294
Step-by-step explanation:
Use the formula
[tex]a_{n} = a_{1} r^{n - 1}[/tex]
In your problem [tex]a_{1}[/tex] = 6 r = -3 n = 11
11th term = [tex]a_{11}[/tex] = [tex]6(-3)^{11 - 1} = 6(-3)^{10}[/tex] = 6(59049)
= 354294
