topjm [15]

sides 2 * 6 * 4 =48 and 6*4=24

bottom 6*2.5 =15

2.5*4=10

10*2=20 that's the area of 2 smaller sides

Step-by-step explanation:

we add up the dimensions together 48+20+15=83

so the final equation becomes (6*2.5)+2(2.5*4)+2*(6*4)=83

The opening of the tunnel can be modeled by the graph of the equation y=-0.18x^2+4.4x-12 where x and y are measured in feet. Fin
Molodets [167]
1. To find the vertex of a parabolla whose equation is written in the standard form, you must apply the following proccedure:
 
 2. You have:
 
 y=-0.18x²+4.4x-12 
 
 a=-0.18
 b=4.4
 
 3. You must apply the following formula:
<span> 
 x=-b/2a
 x=-4.4/2(-0.18)
 x=-4.4/-0.36
 x=12.22
 
 4. When you susbtitute x=12.22 into the equation </span>y=-0.18x²+4.4x-12, you obtain:
 
 y=-0.18x²+4.4x-12
 y=-0.18(12.22)²<span>+4.4(12.22)-12
</span> y=14.88 feet
 
 5. The answer is: The maximum height of the tunnel is <span>14.88 feet</span>

At the beginning of six grade Kevin was 4’10” tall. at the end of ninth-grade he was 5’9” tall. what was the percentage of incre
tankabanditka [31]

Answer:

<u>Kevin's height increased 19.05%</u>

Step-by-step explanation:

Height of Kevin at the beginning of sixth grade = 4’10”

Height of Kevin at the end of ninth grade = 5’9”

What was the percentage of increase in Kevin height?

For answering this question, we should convert Kevin's heights to decimal number, this way:

1 feet = 12 inches

4’10” = 4 10/12 = 4.83

5’9” = 5 9/12 = 5.75

Now, let's use the Direct Rule of Three:

Height     Percentage

4.83              100

5.75                 x

***********************************

4.83x = 5.75 * 100

4.83x = 575

x = 575/4.83

x = 119.05

119.05 - 100 = 19.05

<u>Kevin's height increased 19.05%</u>

A sled is being pulled with a force of 120 N at an angle of 35o with the horizontal. How far is the sled pulled if 1100 J of wor
natta225 [31]

Answer:11.2 m

Step-by-step explanation:

Given

Force Applied F=120 N

inclination \theta =35^{\circ}

Force has two components here i.e. F\cos \theta and F\sin \theta

F\cos \theta will will do work

Work done is given by force time displacement

W=120\cdot \cos 35\times s

1100=120\times \cos 35\times s

s=11.19\approx 11.2 m
