Fifty percent of the surface area of the bread is crust. What is the height h?
Vikentia [17]

Answer:

The height h is 5\ cm

Step-by-step explanation:

we know that

The surface area of the bread is equal to

SA=2B+Ph\\

where

B is the area of the base

P is the perimeter of the base

h is the height

In this problem

If fifty percent of the surface area of the bread is crust

then

2B=Ph\\

substitute the values

2(10)(10)=4(10)h\\

200=40h\\

h=200/40=5\ cm

Which of the following shows the division problem below in synthetic division form?
MissTica

Answer:

Choice D

Step-by-step explanation:

Given division problem is \frac{5x^2+9x-6}{x+2}

Now we need to find about which of the given choices shows the division problem below in synthetic division form.

To convert into synthetic division form, we set denominator =0 so we get

x+2=0 or x=-2

Hence we divide by -2

Now collect coefficients of numerator for the dividend part

Coefficients of  5x^2+9x-6 are 5 9 -6

Hence correct choice is D

* 6. You plan to rent a car from XYZ Car Rental Company for a flat rate of $35 a day.
Anni [7]

Answer:

f(x) = \left \{ {{35x + 10, x \leq 3} \atop {35x + 5x = 40x, x>3}} \right.

Step-by-step explanation:

Let x be the number of days you want to rent

The flat rate for car rental is $35 a day

As for insurance, $10 for 3 days or fewer, and $5 per day if more than 3 days that is

\left \{ {{10, x \leq 3} \atop {5x, x>3}} \right.

Combine this with the flat rental rate $35 a day and we have

f(x) = \left \{ {{35x + 10, x \leq 3} \atop {35x + 5x = 40x, x>3}} \right.

Two runners are saving money to attend a marathon. The first runner has $112 in savings, received a $45 gift from a friend, and
scoundrel [369]

Answer:

The correct answer is the last option, that is, 112 + 25m + 45 = 50 + 60m

Step-by-step explanation:

We have been given that the first runner has $112 in savings, received a $45 gift from a friend, and will save $25 each month. Therefore, amount of money in the account of first running after m months will be: 112+45+25m

We have been given that the second runner has $50 in savings and will save $60 each month. Therefore, amount of money in the account of second running after m months will be: 50 + 60m

In order for amount of money to be equal in accounts of both the runners, we set up:

112+45+25m=50+60m

Upon rewriting the left hand side using commutative law, we get:

112+25m+45=50+60m

Therefore, we can see that the last option is the correct answer.
