Answer:

53 divided by 3 would be $17.66

so 17.66 times 9 would be $158.94

Answer:

158.4 dollars

Step-by-step explanation:

so first of all the three tickets were 53 dollars so we divide the dollars and the no of tickets like this 53÷3 = 17.6 dollars

so since each ticket is 17.6 dollars now we know that Rosie wants to purchase 9 tickets so we will multiply the no of tickets by dollars per ticket like this

9×17.6= 158.4 dollars

and 158.4 is your answer

Answer:

35

Step-by-step explanation:

Numbers that add up to 8 and number combinations

0 and 8: 80, 08

1 and 7: 17, 71

2 and 6: 26, 62

3 and 5: 35, 53

4 and 4: 44

Since the number must be between 25 and 40, the only possible numbers are 26 and 35

Since 26 is not the answer, the number is 35

Answer:

18mm

Step-by-step explanation:

in the triangle we will say:

36=x^2 +x^2

36=2x^2

so x will be = root 18

as the area = x*x

so root 18 * root18=18mm^2

Answer:

Slope = 2

Step-by-step explanation:

(x₁ , y₁) = ( 1 , 1)   & (x₂,y₂) = (-1,-3)

[tex]Slope=\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{-3-1}{-1-1}\\\\=\dfrac{-4}{-2}\\\\=2[/tex]

Answer:

48

Step-by-step explanation:

80x40%=80x.4=32 boys. 80 students-32 boys = 48 girls

Answer:

Slope = -4

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes, which means that multiplying their slopes result in a product of -1. Given the equation, x - 4y = - 12:

Transform the equation into its slope-intercept form, y = mx + b:

x - 4y  = - 12

x - x - 4y = - x - 12

-4y = -x - 12

Divide both sides by -4:

[tex]\frac{-4y}{-4} = \frac{-x - 12}{-4}[/tex]

y =  ¼x + 3  ⇒ (This is the slope-intercept form of the given standard equation, x - 4y  = - 12).

Since the slope of the given equation is ¼, then it means that its negative reciprocal must be - 4:

(¼) (-4) = -1

Therefore, the slope of the line perpendicular to x - 4y = - 12 is - 4.

Answer:

Step-by-step explanation:

6) Area of rectangle = 78.5 sq . cm

length * width = 78.5

15.7 * width = 78.5

        Width = 78.5/15.7

                  = 5 cm

7) circumference of circle = 44 cm

[tex]2\pi r = 44 \\\\2*\dfrac{22}{7}*r=44\\\\r = 44*\dfrac{7}{2*22}\\\\r = 7[/tex]

r = 7 cm

In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. ... We then represent the data using a bar graph. The number of each of the supplies is represented with bars. The more the height of the bar, the more is the number of the supply or item used.

Step-by-step explanation:

Answer: The measurement of ∠EFG is equal to 70°.

Step-by-step explanation:

Two interior angles who are always opposite to an exterior angle sums to that exterior angle. So we would start as the following:

(6x - 10) + 38 = 7x + 18

In order to find m∠EFG, we must first isolate x. In order to do that, we first add like terms together on both sides.

(6x - 10) + 38 = 7x + 18

6x + 28 = 7x + 18

We then substract 18 on both sides.

6x + 10 = 7x

We finally substract 6x from both sides in order to have the value of x.

x = 10

Now that we know the value of x, we substitute it in our the equation in order to find m∠EFG.

m∠EFG = 6x + 10

m∠EFG = 6(10) + 10

m∠EFG = 60 + 10

m∠EFG = 70

Answer:

50°

Step-by-step explanation:

( 7x + 18 )° = ( 6x - 10 )° + 38°

7x + 18 = 6x - 10 + 38

7x - 6x = 28 - 18

x = 10

m∠EFG = 6(10) - 10

m∠EFG = 50°

X - 2 = 10

To solve for x add 2 to both sides of the equal sign:

X = 12

Answer:

x = 12

Step-by-step explanation:

Add 2 to both sides of the equation

x−2=10

−2+2=10+2

Simplify

Solution:

x = 12

Answer:

To write a linear expression in standard form, rearrange the terms in alphabetical order.

[tex]2.9[/tex] × [tex]10^3[/tex]

But, if you need to write it in scientific notation, the answer is 2,900.

Answer:

B

Step-by-step explanation:

349 ---100%

x ------ 20%

x= (349×20)÷100

x=69.8

349-69.8=279.2

279.2 ---100%

x-----7%

x=(279.2×7)÷100

x=19.54

Final result

279.2+19.54=298.74

And final result is B

The total price of the television is B. $297.74

Given that,

Based on the above information, the calculation is as follows:

[tex]= (\$349 \times (1- 0.20) + \$349 \times (1- 0.20) \times 0.07)\\\\= \$279.20 + \$19.544[/tex]

= $297.74
