Answer:
The output is 5
Step-by-step explanation:
-4 is the input (x value). To find the output, you have to find where -4 is on the line. -4 is on the line when 5 is the y coordinate (output).
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

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.

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
71
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

PLEASE HELP ME!!!
I don't understand....
If possible, please explain!
Answer:
55
Step-by-step explanation:
Since this is an isosceles triangle, the angles at the bases of the identical legs must be equal
<A = <C
3x+40 =x+50
Subtract x from each side
3x-x+40 = x+50-x
2x +40 = 50
Subtract 40 from each side
2x+40-40=50-40
2x = 10
Divide each side by 2
2x/2=10/2
x = 5
We want to find <A
3x+40
3(5)+40

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.

what is the answer to 18x-5 < 3(6x-2) ?
Answer:
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.
