Answer:

C) 10 inches

Step-by-step explanation:

I think the simplest way to do this is as follows:

divide 75 by 15 to get how many times you need to multiply 2in by

75/15=5

since 15(5)=75 or the actual size of the airplane,

2(5)=10 which is the size of the model airplane

hjlf

Answer:

A. 42.5

Step-by-step explanation:

The triangle shown is an isosceles triangle. An isosceles triangle haas two of its sides and base angles equal. Hence;

<ACB = <ABC (Base angles are equal)

Given

<ACB = 42.5°

Required

<ABC

<em>According to the law above which says <ACB = <ABC , hence <ABC is also equal to 42.5°</em>

Answer: The length of the plot is 13.3 meters

Step-by-step explanation: The plot has been described as rectangular and naturally you would have a longer side (length) and a shorter side (width). If the area has been given as 100 square meters, and the area of a rectangle equals L x W, having been given the dimension of one side, we can now calculate the other side as,

Area = L x W

100 = L x 7.5

By cross multiplication we now have

100/7.5 = L

13.33 = L

Approximately to the nearest tenth,

L = 13.3 meters

The area of a rectangle is w^2+4w=60 where w is the width. find the width.

Svetradugi [14.3K]

The width of rectangle is 6.

Step-by-step explanation:

Given,

Area of rectangle; w²+4w=60

As w is the width, we will solve the equation to find w.

$w^2+4w=60$

Subtracting 60 from both sides

$w^2+4w-60=0$

Factorizing the equation;

$w^2+10w-6w-60=0\\w(w+10)-6(w+10)=0\\(w+10)(w-6)=0$

Either,

w+10=0 => w=-10

Or,

w-6=0 =>w=6

As width cannot be negative, therefore

Width = 6

The width of rectangle is 6.

Barb is a freshman attending a 4-year college. She has been approved for a $12000

tester [92]

Answer:

The amount in interest accruable to the U.S. Department of Education after 4.5 years is $2,882.33

Step-by-step explanation:

The given parameters are;

The amount, P of subsidized federal loan Barb has been approved for = $12,000

The interest rate at which the loan was approved, r = 4.29%

The duration of the loan = 10 years

The interest after 4.5 years is given as follows;

$A = P \times \left (1 + \dfrac{r}{n} \right ) ^{n \cdot t}$

Where;

A = The total amount of the loan plus interest after a given time period

n = The number of compounding of the interest per annum

Plugging in the values, we get;

$A = 12,000 \times \left (1 + 0.049 \right ) ^{4.5} \approx 14,882.33$

The interest, i, is therefore given as follows;

i = A - P = 14,882.33 - 12,000 = 2,882.33

The interest, i after 4.5 years = $2,882.33

The amount in interest accruable to the U.S. Department of Education after 4.5 years = $2,882.33.
