A: 184

1.) find the area of the two sides (length*height)*2
5*8=40*2=80

2.) Find the area of the adjacent sides (Width*height)*2
5*4=20*2=40

3.) Find the area of the ends (length*width)*2
4*8 =32*2=64

4.) add the three areas together
40+80+64=184

Answer:

a) The Total fee, that Mike charges for 4 hours of instruction is $152

b) The total fee, that Tony charges for 4 hours of instruction is $148

c) The difference between total fee Mike and Tony charge for 4 hours of instructions is $4

Step-by-step explanation:

a) What is the total fee, that mike charges for 4 hours of instruction.

Mike charges $12 for travel expenses and $35 per hour for instruction.

So, the equation will be: $y=35h+12$ where h is number of hours and y is cost

Put h=4 and find cost

$y=35h+12\\y=35(4)+12\\y=140+12\\y=152\\$

So, the Total fee, that Mike charges for 4 hours of instruction is $152

b) What is the total fee, that Tony charges for 4 hours of instruction

Tony's fee can be modelled by C=32h+20 where h is number of hours and C is cost

Put h=4

$C=32h+20\\C=32(4)+20\\C=128+20\\C=148$

So, the total fee, that Tony charges for 4 hours of instruction is $148

c) What is the difference between total fee Mike and Tony charge for 4 hours of instructions.

Cost for Mike = $152

Cost for Tony = $148

Difference = 152 - 148 = 4

So, the difference between total fee Mike and Tony charge for 4 hours of instructions is $4

Geometry math question no Guessing and Please show work thank you

Advocard [28]

Given distance are on straight line

we can break the line in few parts and the complete length can be taken as sum of length of each part

so here

We can see :

JD+ DM= 84 when we plug values we get

17 + DM = 84

DM= 84 - 17

DM= 67

Evaluate 10m +\dfrac {n^2}410m+ 4 n 2 10, m, plus, start fraction, n, start superscript, 2, end superscript, divided by, 4, en

guapka [62]

It was hard to read your question because that is not typed in proper format. Best that i can read your expression is :

$10m+\frac{n^2}{4}$

Now we have to evaluate it for given values m=5 and n=4

So let's plug these values into given expression.

$10m+\frac{n^2}{4}$

$= 10(5)+\frac{4^2}{4}$

$= 10(5)+\frac{16}{4}$

$= 10(5)+4$

$= 50+4$

$= 54$

Hence final answer is 54.

Suppose p varies directly with d and p=3 when d=5. What is the value of d when p=12

ololo11 [35]

Answer:

Answer:  d is 20 

Step-by-step explanation:

${ \rm{p \: \alpha \: d}} \\ \\ { \rm{p = kd}}$

k is a constant of proportionality

• When p = 3, d = 5.

${ \rm{3 = (k \times 5)}} \\ \\ { \rm{k = \frac{3}{5} }}$

• Therefore, equation becomes;

${ \rm{p = \frac{3}{5} d}}$

• Let's find d when p is 12;

${ \rm{12 = \frac{3}{5}d }} \\ \\ { \rm{d = \frac{12 \times 5}{3} }} \\ \\ { \underline{ \underline{ \rm{ \: \: d = 20 \: \: }}}}$
