The formula to find the surface area of a rectangular prism is SA = 2ab + 2bc + 2ac, where a, b, and c all equal one side of the prism.
To solve this, plug in the value for surface area and the values of the known sides. let’s say a = 3cm and b =5cm and c = y cm. It doesn’t matter with value gets assigned to which letter.
SA = 2ab + 2bc + 2ac
158 = 2(3)(5) + 2(5)(y) + 2(3)(y)
158 = 30 + 10y + 6y
158 = 30 + 16y
128 = 16y
y = 8 cm
Find FD(round to the nearest tenth) please and thank you!
Answers
Answer:
FD = 25.9
Step-by-step explanation:
13x - 16 = 4x + 11
9x = 27
x = 3
using Pythagorean theorem:
FD² = 12² + [4(3) + 11]²
FD² = 144 + 23² = 144 + 529 = 673
FD = 25.94
Roadsign cast of shadow that is 4 feet tall at the same time a 6 foot man standing next to the sign cast a shadow of those 2.4 feet long right and solve a proportion to find how tall the sign is
Answers
Answer:
10 feets
Step-by-step explanation:
Given that:
Road sign shadow (Rs) = 4 feets
Height of man (Hm) = 6
Man shadow (Ms) = 2.4 feets
Height of road sign (Hr) = x
Height of road sign / shadow of road sign = height of man / shadow of man
Hr/Rs = Hm / Ms
x / 4 = 6 / 2.4
Cross multiply :
4*6 = 2.4*x
24 = 2.4x
x = 24 / 2.4
x = 10 feets
Hence, height of road sign = 10 feets
Mr. Smith is flying his single-engine plane at an altitude of 2400 feet. He sees a cornfield at an angle of depression of 30º. What is his horizontal distance to the cornfield?
Answers
Answer:
Height of the fighter plane =1.5km=1500 m
Speed of the fighter plane, v=720km/h=200 m/s
Let be the angle with the vertical so that the shell hits the plane. The situation is shown in the given figure.
Muzzle velocity of the gun, u=600 m/s
Time taken by the shell to hit the plane =t
Horizontal distance travelled by the shell =u

Distance travelled by the plane =vt
The shell hits the plane. Hence, these two distances must be equal.

Use the equation editor below to state how many minutes there are in 1 10 hour. Then, calculate how many minutes are equal to 5 × 1 10 hour
Answers
Answer:
Number of minutes in [tex](5\times \frac{1}{10})[/tex] hours = 30 minutes
Step-by-step explanation:
Number of minutes in 1 hour = 60 minutes
Number of minutes in [tex]\frac{1}{10}[/tex] hours = [tex]\frac{60}{10}[/tex] minutes
= 6 minutes
Therefore, number of minutes in [tex]5\times \frac{1}{10}[/tex] hours = 5 × 6
= 30 minutes

Which is the completely factored form of 4x3 + 10x2 – 6x?
2(x + 3)(2x – 1)
2x(x + 3)(2x – 1)
2x(x – 3)(2x – 1)
2(x – 3)(2x + 1)
Answers
Answer:
B. 2x(x + 3)(2x – 1)
Step-by-step explanation:
A. 2(x + 3)(2x – 1)
= (2x + 6)(2x - 1)
= 4x² - 2x + 12x - 6
= 4x² + 10x - 6
B. 2x(x + 3)(2x – 1)
= (2x² + 6x)(2x - 1)
= 4x³ - 2x² + 12x² - 6x
= 4x³ + 10x² - 6x
C. 2x(x – 3)(2x – 1)
= (2x² - 6x)(2x - 1)
= 4x³ - 2x² - 12x² + 6x
= 4x³ - 14x² + 6x
D. 2(x – 3)(2x + 1)
= (2x - 6)(2x + 1)
= 4x² + 2x - 12x - 6
= 4x² - 10x - 6
The completely factored form of 4x3 + 10x2 – 6x is 2x(x + 3)(2x – 1)

1. Lizzy opened an ice cream parlor in her neighborhood selling homemade ice cream. She has a goal to create 80 new ice cream flavors. If she already created 37 flavors, how many more flavors does she still need to create?
2. A staples truck is delivering notebooks to CMS. There are 212 boxes with 198 notebooks in each box. How many total notebooks are there?
Answers
Step-by-step explanation:
2) 212*198 = 41 976
1) 80-37 = 43
9514 1404 393
Answer:
1. SCR (or PPW). 43 more flavors
2. GLT. 41,976 notebooks
Step-by-step explanation:
1. Conceptual key: SCR
Lizzy is starting with 37 flavors. She wants a result of 80 flavors, so the change can be computed from ...
37 + x = 80
x = 80 -37 = 43
Lizzy needs to create 43 more flavors.
__
Additional comment
This might also be considered to be using the PPW pattern, as both the number she has and the number she creates make up the whole number. The SCR key may better apply to cases where a "rate of change" is involved. There is no rate of change in this problem.
_____
2. Conceptual key: GLT
There are 212 groups of 198 notebooks, so the total is the number of groups times the number in each group.
(212 boxes)(198 notebooks/box) = 41,976 notebooks
