A 180 feet
B. 300 feet
C. 240 feet
D. 120 feet

Answer:

a) 40 inches

b) No it will not fit inside

Step-by-step explanation:

Angharad is buying a new 50-inch screen TV (remember that TV screens are measured along the diagonal )

a) If it is 30 inches tall, how wide is the screen ?

Diagonal ² = Width² + Height²

Diagonal = 50 inches

Height = 30 inches

50² = Width² + 30²

Width² = 50² - 30²

Width = √50² - 30²

Width = √(1600)

Width = 40 inches

b) Her TV cabinet is 30 inches wide .will the TV fit inside it ?

No it will not fit inside

This is because, the width of the TV is the above calculation is 40 inches. This is wider than the width of the TV cabinet, hence, it won't fit inside

Answer:

$35

Step-by-step explanation:

Find the cost of 1 apple

$25/50 = 0.5

1 apple costs 50 cents/ 0.5 dollar

Multiply by 70 to find the cost of 70 apples

$0.5 x 70 apples = 35

$37.50. ...................

Answer:

e

Step-by-step explanation:

Answer:

35

Step-by-step explanation:

Since you know that a triangle must have a total of 180 degrees and a right triangle is 90 degrees then you just subtract 90 from 180 and you get 90. Then subtract 55 from 90 and you get 35 which is the only possible answer.

Answer:

See both answers in the explanation

Step-by-step explanation:

Given data

Cost of dinner= $32

TIp=18%

Let us find the amount of the tip

=18/100*32

=0.18*32

=$5.76

Hence the total amount paid is

=5.76+32

=$37.76

The Tip is

=$5.76

Answer:

  64 -16π square units

Step-by-step explanation:

The area of the square is ...

  A = (8 units)^2 = 64 units^2

The area of the circle is ...

  A = πr^2 = π(4 units)^2 = 16π units^2

The shaded area is the difference:

  shaded area = (64 -16π) units^2.

Answer:

It is the first answer choice

Answer:

B: Using x and y factor results in an expression of greater value than using x and y as terms.

Step-by-step explanation:

For her first expression, x and y are factors;

xy

For her second expression, x and y are written as terms;

x + y

For x and y are both negative integers, then;

-x * -y = xy  ............... 1

-x + (-y) = - x - y

            = - (x + y)  .............. 2

Therefore, the value of x and y factors is greater than that when x and y are as terms. Thus the correct option is B.

Answer:

c 116

Step-by-step explanation:

Answer:

The answer is c

Step-by-step explanation:

Given:

The equations of a system of equations are

[tex]y=-2x^2+3x-1[/tex]

[tex]x+y=-1[/tex]

To find:

The solution of the given system of equations.

Solution:

We have,

[tex]y=-2x^2+3x-1[/tex]           ...(i)

[tex]x+y=-1[/tex]                      ...(ii)

Using (i) and (ii), we get

[tex]x+(-2x^2+3x-1)=-1[/tex]

[tex]x-2x^2+3x-1+1=0[/tex]

[tex]-2x^2+4x=0[/tex]

Taking out the common factors.

[tex]2x(-x+2)=0[/tex]

Using zero product property,we get

[tex]2x=0[/tex] and [tex]-x+2=0[/tex]

[tex]x=0[/tex] and [tex]2=x[/tex]

For x=0, we have

[tex]0+y=-1[/tex]

[tex]y=-1[/tex]

For x=2, we have

[tex]2+y=-1[/tex]

[tex]y=-1-2[/tex]

[tex]y=-3[/tex]

Therefore, the two solutions of the given system of equations are (0,-1) and (2,-3).

Answer:

Isabella earn [tex]5604.54[/tex] more money than  Gabriel

Step-by-step explanation:

As we know

Compound interest (CI) [tex]= P (1 + \frac{r}{n})^{nt}[/tex]

P is the principal amount

t is the time period

n is the number of time periods

r is the rate of interest

a)  CI for  Gabriel

[tex]= 77000 (1 + \frac{3}{100*12})^{12*6}[/tex] [tex]= 92165.03[/tex] dollars

b) CI for Isabella

[tex]= 77000 (1 + \frac{4}{100*4})^{4*6}[/tex] [tex]= 97769.57[/tex] dollars

Isabella earn [tex]5604.54[/tex] more money than  Gabriel

Answer: k = 27

Step-by-step explanation:

Here's the complete question:

Write the word sentence as an equation. Then solve the equation. A number k increased by 7 is 34.

An increase in k simply means that there's an addition. This will be:

k + 7 = 34

k = 34 - 7

k = 27

Therefore, the value of k is 27

Answer:

84 tiles

Step-by-step explanation:

Given that :

Figure 2 = 8 tiles

Figure 5 = 14 tiles

Growth rate :

(Figure 5 - figure 2)x= 14 - 8

3x = 6

x = 6/3

x = 2

(Figure 40 - figure 2) = 38 * x

Initial number of tiles + 38x

8 + 38(2)

8 + 76

= 84

Figure 40 = 84 tiles

Answer:

B

Step-by-step explanation:

The function's zeroes results in vertical asymptotes. As one is at x = 1 and the other at x = -2, the zeroes must be (x-1) and (x+2), which only B contains in the numerator.
