Ade has two similar scale models of the same pyramid. The first model has a
height of 5 inches and a surface area of 80.9 square inches. The linear dimensions
of the second model are each increased by a common factor so that the height of
the second model is 15 inches. To the nearest tenth of a square inch, what is the
surface area of the second model?
Please help!
Answer: 242.7 square inches
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
The first model has a height of 5 inches and a surface area of 80.9 square inches:
The proportion is : height/ surface area= 5 in / 80.9 in2
For a height of 15 inches
15 in/ x in2
So:
5/80.9 = 15/x
x= 15/ (5/80.9 )
x= 242.7 square inches

What is the circumference
Answer:
Circumfrence is the distance around the circle. Sort of like a perimeter of a square.
Step-by-step explanation:
To solve the picture: the answer is 8 pi cm. The formula for circumference is C= 2pir, in which r is the radius. This means multiply the radius by 2 and then by pi. This is also known as C= dpi (d meaning diameter)

The area of a 2D form is the amount of space within its perimeter. The area of the composite figure is 249 cm².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The area of the composite figure can be written as,
Area = ABCG + DEFG = (4×10.5) + (11.5×18) = 42+207 = 249cm²
Hence, the area of the composite figure is 249 cm².

Zack delivers mail for the post office. Every day he walks a 7-mile route. How many miles does Zack walk in one month if he works 22 days that month?
Solve the problem. Multiply 22 and 7 and you 154 and that's your answer
154 miles
Answer: 154
Step-by-step explanation:
Hi, to answer this question we simply have to multiply the distance that he walks every day (7 miles) by the number of days that he works in a month (22).
Mathematically speaking:
7m x 22d = 154 miles
Zack walks 154 miles in one month.

Second column labeled less than 40 dollars a week with entries W, Y, almost equals 0.43. Third column labeled greater than or equal to 40 dollars a week with entries X, Z, almost equals 0.57. Fourth column labeled total with entries 1.0, 1.0, 1.0 Which value should he use for Y? Round to the nearest hundredth. 0.19 0.45 0.82 0.90

____ | <40 | 》40 | Total
< 30 | W | X | 1.0
》30 | Y | Z | 1.0
Total | 0.43 | 0.57 | 1.0
Since W, X, Y and Z are conditions frequency, they can't be negative
Therefore,
W and Y are both less than 0.43
X and Z are both less than 0.57
The only option less than 0.43 is 0.19 (for Y)

Answer:
d =13 cm
r = 6.5 cm
Step-by-step explanation:
The diameter is the distance across the circle, going through the center
d = 13 cm
The radius is 1/2 of the diameter
r = d/2 = 13/2 = 6.5 cm
Answer:
Radius is 6.5
Diameter is 13
Step-by-step explanation:
The diameter is the distance across the circle. The radius is half the distance across the circle.
1. On a quiet day without many witnesses, a 4.5 ft victim is shot by a sniper that
was in a tower 780 ft away. If the angle of elevation is 48° from the victim, at
what vertical distance did the sniper shoot from?
Answer:
The sniper shoot from 870.775 feet vertical distance.
Step-by-step explanation:
Refer the attached figure
Height of victim = AB = 4.5 ft.
Distance between tower and victim BC = 780 feet
The angle of elevation =[tex]\angle DAE = 48^{\circ}[/tex]
Let DE be x
AB = CE = 4.5 feet
BC =AE = 780 feet
Height of tower = DE+CE=x+4.5
In ΔDAE
[tex]\frac{Perpendicular}{Base}=Tan\theta\\\frac{DE}{AE}=Tan 48^{\circ}\\\frac{x}{780}=1.11061\\x=1.11061 \times 780\\x=866.275[/tex]
Height of tower = DE+CE=x+4.5=866.275+4.5=870.775 feet
Hence the sniper shoot from 870.775 feet vertical distance.

No solution
Step-by-step explanation:
18x - 5 < 3(6x - 2) Distribute the 3 to (6x - 2)
18x - 5 < 18x - 6
-18x -18x Subtract 18x from both sides
-5 < -6 There is no solution because -5 is not less than -6.

Using Milan's simulation, what is the probability of rolling a 5 on the number cube and the coin landing on tails?
11

10,000
Answer:
P(Both) = 781/10000
Solution:
P(T) = 71/100
P(6) = 11/100
P(Both) = P(T) * P(6)
(Both) = 71/100 * 11/100
P(both) = (71 * 11) / 10000
P(Both) = 781/10000
Brainliest please, I need a few more ;D
Short Answer D
Remark
Thank you for trying to pose the question so clearly.
Givens
T = 71 times
5 being rolled = 11
Substitution and solution.
P(T) = 71/100
P(6) = 11/100
P(Both) = P(T) * P(6)
P(Both) = 71/100 * 11/100
P(both) = (71 * 11) / 10000
P(Both) = 781/10000
