These are SIMILAR figures. Fill in the missing values for the angles and sides
Answer:
75 62 22 30 65 18
Step-by-step explanation:
Given that the figures are similar figures, then:
x and y in the Parallelograms:
x = 88
y = 118°
x, y, and z in the Hexagons:
x = 164°
y = 36
z = 33
x, y, and z in the Triangles:
x = 10
y = 21
z = 75°
What are Similar Figures?Similar figures have pairs of angles that have the same degree measure, and the ratio of their corresponding sides are equal.
Given that the pairs of figures are similar, let's find the missing angles and sides as shown below:
Find x and y in the Parallelograms:
x/66 = 100/75
Cross multiply
x = (100 × 66)/75
x = 88
y = 118° (opposite angles of a parallelogram are congruent)
Find x, y, and z in the Hexagons:
x = 164° (congruent angles)
y/54 = 20/30
y = 36
22/z = 20/30
z = 33
Find x, y, and z in the Triangles:
x/15 = 12/18
x = 10
14/y = 12/18
y = 21
z = 180 - 65 - 40 = 75°

Find the volume of each pyramid. Round to the nearest tenth if necessary.
triangular pyramid: triangle base, 6.1 cm; triangle height, 6.7 cm; pyramid height, 10.4 cm
a
141.7 cm3
b
212.5 cm3
c
53.1 cm3
d
70.8 cm3
Answer:
The formula for the pyramid’s volume is given by one-third of the product of the area of the base to its height. Such as: Volume = 1/3 x Area of the Base x Height. V = ⅓ A × H. Where V = Volume, A = Area and H = height.

Kasey and Jordan are counting calories while eating lunch in the school cafeteria. in one week, Kasey had 10 slices of pizza and 5 cups of fruit salad. Jordan had 6 slices of pizza and 7 cups of fruit salad. Kasey’s calorie count was 3070 and Jordan’s was 2522. How many calories are in a slice of pizza?
Answer:
222 calories from the pizza
Step-by-step explanation:
nandhini123-
Given:
slices of pizza ate by Kasey =10
cups of fruit salad by Kasey= 5
slices of pizza ate by Jordan = 6
cups of fruit salad by Jordan= 7
Kasey's calorie count = 3070
Jordan calorie count = 2522
To Find:
calories Jordan got from pizza =?
Solution:
Let the calorie of one slice of pizza be x
and the calorie of one cup of fruit salad be y
According to the question, the equation that represents the Kasey's Scenario is
10x + 5y = 3070-------------------------------------(1)
Similarly the equation that represents the Jordan Scenario is
6x + 7y = 2522--------------------------------------(2)
multiply eq(1) by 6 we get
60x + 30y = 18420---------------------------------(3)
multiply eq(2) by 10 we get,
60x + 70y = 25220----------------------------------(4)
Subtracting eq (3) from (4) we get
60x + 70y = 25220
60x + 30y = 18420
(-) (-) (-)
-----------------------------------
0x + 40y = 6800
---------------------------------
=>40 y = 6800
=>y =
=> y = 170
So calorie of one cup fruit salad is = 170 calories
substituting the y values in eq 1 we get
10x + 5(170) = 3070
10x + 850 = 3070
10x = 3070 - 850
10x = 2220
x =
x= 222
So calorie of one pizza slice = 222 calories
Now we know that Jordan ate 6 slices of pizza
calories Jordan get from pizza = number of pizza he ate X calore per pizza slice
=> 6 x 222
=>1332 calories
