Answer:

3 quarters and 19 nickles

Step-by-step explanation:

.

Answer:

x= 1

y= -2

Step-by-step explanation:

equation (1): y= -3x+1

equation (2): y=x-3

solve the system of equations by substitution:

step1: sub ( x-3 ) for y in equation 1:

y = -3x+1

x-3 = -3x+1

step2: simplify the equation to get x:

(add 3 for both sides)

x = -3x+4

(add 3x for both sides)

4x = 4

(divide 4 from both sides)

x = 1

step3: sub the value of x (x=1) in equation 2:

y = x-3

y = 1-3

step4: solve the equation to get y:

y = -2

Answer:

10 is the GCF

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

Answer:

x = 7.4

Step-by-step explanation:

cos(42°) = x/10 or distance from bases / rope length

Using the calculator find the value of cos(42°):

cos(42°) = 0.74 = x/10

Find x using the value of cos(42°):

x/10 = 0.74

x = 7.4

Answer: B. The product of P and S is always a rational number.

Step-by-step explanation: The product AND sum of two rational numbers will ALWAYS be rational.

reflection and translation.

Given:

The different transformation in the options.

To find:

The transformation that would result in the perimeter of a triangle being different from the perimeter of its image.

Solution:

In option 1,

[tex](x,y)\to (y,x)[/tex]

It represents reflection across the line y=x.

In option 2,

[tex](x,y)\to (x,-y)[/tex]

It represents reflection across the x-axis.

In option 3,

[tex](x,y)\to (4x,4y)[/tex]

It represents dilation by scale factor 4 and the center of dilation is at origin.

In option 4,

[tex](x,y)\to (x+2,y-5)[/tex]

It represents translation 2 units right and 5 units down.

We know that the reflection and translation are rigid transformations, It means the size and shape of the figure remains the same after transformation.

So, the perimeter of the figure and its image are same in the case of reflection and translation.

But dilation is not a rigid transformation. In dilation, the figure is similar to its image. So, the perimeter of the figure and its image are different in the case of dilation.

Therefore, the correct option is 3.

Just kidding.

54 ÷ (3 × 3) × 2

54 ÷ 9 × 2

6 × 2

12

Answer:

y would be 67 as well.

Step-by-step explanation:

they are alternate interior angles. hope it helps

In part (a) the missing angle of a triangle is 70 degrees and in part (b) the missing angle is 67 degrees.

In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.

Part(a)

We have a triangle shown in the picture.

The two lengths of a triangle are equal.

The angle opposite to the sides will be equal.

As we know,

The triangle's interior angles add up to 180°.

180 = 55 + 55 + x

x = 180 - 110

x = 70 degrees

In part (b)

There are two parallel lines shown in the picture.

The angle y will be the same as 67 degrees because two parallel lines are cut by a transversal line.

Thus, in the part (a) the missing angle of a triangle is 70 degrees and in part (b) the missing angle is 67 degrees.

Answer:

[tex]\frac{7}{8}[/tex]

Step-by-step explanation:

Find the average by adding the 2 fractions and dividing the sum by 2

[tex]\frac{1}{2}[/tex] + 1 [tex]\frac{1}{4}[/tex]

= [tex]\frac{1}{2}[/tex] + [tex]\frac{5}{4}[/tex]

= [tex]\frac{2}{4}[/tex] + [tex]\frac{5}{4}[/tex]

= [tex]\frac{7}{4}[/tex]

Then

[tex]\frac{7}{4}[/tex] ÷ 2

= [tex]\frac{7}{4}[/tex] × [tex]\frac{1}{2}[/tex]

= [tex]\frac{7}{8}[/tex]

I DON'T KNOW IF THIS IS CORRECT IM SORRY IF IT'S WRONG!!!!!!

Answer:

no this is because 28-8+9=29 and 20-9=11

Step-by-step explanation:

Answer:

Her equation is not balanced.

Because 28 - 8 + 9 = 20 - 9

                 29 = 11 ( its not balanced)

She put the  same symbol or sign on both side.Here she put different sign on both side .so this equation is not balanced.

Step-by-step explanation:

Answer:

b = 5√3 (units)

Step-by-step explanation:

To solve this problem, use the pythagorean theorem, where a^2+b^2 = c^2, a and b are the legs of the triangle and c is the hypotenuse.

In this case, we are finding the missing leg, and we were given one of the legs and the hypotenuse.

a^2+b^2 = c^2 (pythagorean therorm)

5^2+b^2 = 10^2 (substitute one leg and the hypotenuse)

25+b^2 = 100 (square the numbers)

b^2 = 75 (subtract 25 from both sides)

b = √75

b = √25 * √3 (factor out√75)

b = 5 * √3 (find square root of√25)

b = 5√3

Hope I was able to help! Good Luck!

Answer:

363.0449

Step-by-step explanation:

Use the Pythagorean Theorem to solve for the height.

To find a squared, add  13 squared plus 5 squared then find square root.

13.93 is about it.

Then do 13 squared plus 13.93 squared and find the square root.

Answer:

7x° + 11x° = 90°

(Required equation)

Step-by-step explanation:

7x° + 11x° = 90°

(complementary angles)

18x° = 90°

18x = 90

x = 90/18

x = 5
