37. What is the value of x?
(4x + 12)
A 12
C 18
B 19.5
D 60

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. ...................

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:

$33.84

Step-by-step explanation:

Sale price = price - 10% = 90%

90% = 0.9

37.6(0.9) = $33.84

Answer:

A.2 Hours.

B.2 Inches.

Step-by-step explanation:

Its easy,

A. 8 inches = 4 hours, 4 inches = .... hours

4 inches = 8 ÷ 2

Hours: 4 hours ÷ 2 = 2 hours

B. 8 inches = 4 hours, .... inches = 1 hour

1 hour = 4 ÷ 4

Inches: 8 inches ÷ 4 = 2 inches.

Answer: x = 55

Answer:

let the third angle of triangle be y

21°+34°+y=180°[angle sum property]

55°+y=180°

y=180°-55°

y=125°

y+x=180°[by linear pair]

125°+x=180°

x=180°-125°

x=55°

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.

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: im pretty sure it’s the first one

Step-by-step explanation: )

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.

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: 89.4427

Step-by-step explanation: I apologize if I am wrong; I used Pythagorean Thyreom, and I used the formula a=√c^2-b^2 since we are solving for side a.

a=√120^2−80^2

a=√14400−6400

a=√8000

a=89.4427

I hope this is what you are looking for :)

Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then the height of the tower is 89.44 m.

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

The length of a guy's wire supporting a cell tower is 120 meters.

The guy wire is anchored to the ground at a distance of 80 meters from the base of the tower.

We know that the Pythagoras theorem.

[tex]\rm H^2 = P^2 + B^2[/tex]

We have

H = 120 m

B = 80 m

Then by the Pythagoras theorem, we have

[tex]\rm P = \sqrt{H^2 - B^2}\\\\P = \sqrt{120^2 - 80^2}\\\\P = \sqrt{14400 - 6400}\\\\P = \sqrt{8000} = 89.44[/tex]

Thus, the height of the tower is 89.44 m.

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: 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
