Answer:
h = -9
Step-by-step explanation:
2(h + 3.5) = -11

subtract 7 from both sides of the equation:
2h = -18
divide both sides by 2:
h = -9
How many more miles per gallon does Mrs. Sanchez get than Mr. White?

Let x represent number of gallons and y represent numbers of miles.
Mr. White

76
5
152
15
456
18
547.2
miles per gallon
Answer:
5.6 miles per gallon
Step-by-step explanation:
Equation for Mrs Sanchez: y = 36x
The rate of change = miles/gallon for Mrs Sanchez = 36 miles/gallon
Let's find the rate of change for Mr White:
Rate of change = change in y/change in x
Using two pairs of values form the table given, (2.5, 76) and (5, 152),
Rate of change = (152 - 76)/(5 - 2.5) = 76/2.5
Rate of change = miles/gallon = 30.4 miles/gallon
The difference between the miles per gallon of Mrs Sanchez and Mr White = 36 - 30.4 = 5.6 miles per gallon.
Therefore, Mrs Sanchez gets 5.6 miles per gallon than Me White

Which statement is true of the right triangles ABC and DEF?
Area of ABC is greater than area of DEF.
Area of ABC is less than area of DEF.
Area of ABC is equal to the area of DEF.
There is not enough information to compare the areas of triangles ABC and DEF
Answer:
The answer is A
Step-by-step explanation:
edge21
The statement which is true of the right triangles ABC and DEF is Area of ABC is greater than area of DEF.
What is Right Angled Triangle?Right angled triangle are those triangle for which one of the angle is 90 degrees.
Given two right angled triangles, ABC and DEF.
Area of a triangle = 1/2 × base × height
Area of ΔABC = 1/2 × 14 × 6
= 42 square units
Base of ΔDEF = √(7² + 4²) = √65
Height of ΔDEF = √(5² + 8²) = √89
Area of ΔDEF = 1/2 × √65 × √89
= 38.03 square units
Hence the correct option is Area of ABC is greater than area of DEF.

Answer:
BE = 3.5 m
Step-by-step explanation:
Δ ACB and Δ EDB are similar, so the ratios of corresponding sides are equal, that is
[tex]\frac{BE}{BA}[/tex] = [tex]\frac{BD}{BC}[/tex] , substitute values
[tex]\frac{BE}{21}[/tex] = [tex]\frac{3}{18}[/tex] ( cross- multiply )
18 BE = 63 ( divide both sides by 18 )

3. Mary Cunningham offered $456,500 for a home that had been
priced at $569,500. The seller agreed to the offer. A bank is willing
to finance the purchase if she can make a down payment of 20%.
a. What is the amount of the down payment?
b. What is the amount of the mortgage loan?
a. To find the amount of the down payment, we need to multiply the price of the home by the percentage of the down payment required.
How would one define compounding?
Compounding is the method through which interest is added to both the principle balance already in place and the interest that has already been paid. Thus, compounding can be thought of as interest on interest, with the result that returns on interest are magnified over time, or the so-called "magic of compounding."
The price of the home is $456,500 and the down payment percentage is 20%, so:
Down payment = $456,500 x 20% = $456,500 x 0.20 = $91,300
b. To find the amount of the mortgage loan, we can subtract the down payment from the price of the home.
The price of the home is $456,500 and the down payment is $91,300 so:
Mortgage loan = $456,500 - $91,300 = $365,200
Therefore, the amount of the down payment is $91,300 and the amount of the mortgage loan is $365,200.

A model of a volcano has a height of 12 in., and a diameter of 12 in.
What is the approximate volume of the model?
Use 3.14 to approximate pi, and express your final answer as a decimal.
Enter your answer as a decimal in the box.
Answer:
452.16 cm³
Step-by-step explanation:
I assume the shape of the volcano is a cone.
V = (1/3)πr²h
r = d/2 = 12 in./2 = 6 in.
V = (1/3)(3.14)(6 in.)²(12 in.)
V = 452.16 in.²
Answer:
Step-by-step explanation:
Radius r = 6 inches
Height h = 12 inches
volume of cone = πr²h/3 ≈ 3.14∙6²∙12 = 1,356.48 in³
