Answer:

NO

Step-by-step explanation:

The above image shows two triangles. if we look at the top triangle, we notice it's two sides are equal (16 and 16). We therefore have an isosceles right triangle.

looking the second triangle, we notice that one side is 39, the other 40. Since these are the two sides joined at the point of intersection for the two images, and since 39 does not equal 40, the second triangle cannot be an isosceles right triangle. We conclude that the two triangles are not similar.

A 24-ounce can of mixed nuts contains 50% peanuts, 0.20 almonds, 1/10 cashews, and 0.20 hazelnuts. Which of the following represents the total amount of almonds and hazelnuts in the can?

Answers

Answer:

9.6 ounces

Step-by-step explanation:

Step 1

We find the amount of ounces of Almonds

Total amount of nuts in the container = 24 ounces

0.20 of the nuts are almonds.

Hence,

The amount of almonds = 0.20 × 24 ounces

= 4.8 ounces

Step 2

We find the amount of ounces of hazelnuts

Total amount of nuts in the container = 24 ounces

0.20 of the nuts are hazelnuts.

Hence,

The amount of hazelnuts = 0.20 × 24 ounces

= 4.8 ounces

Step 3

Therefore, the total amount of almonds and hazelnuts in the can is

4.8 ounces + 4.8 ounces

= 9.6 ounces

Marco is buying a new skateboard that is on sale for 25% off the regular price is 59.95 Marco knows there's a 7% sales tax what is the total amount he should pay including tax

Answers

Make sure to only tax the price he is paying...
25% is equal to .25 and 25/100 and 1/4
7% is equal to .07 and 7/100

59.95times.25=price

(59.95times.25)times.07= taxes

Then add price and taxes together
14.99price plus 1.05tax=$17.04

6x-8=2x-32 step by step plz

Answers

Answer:

Step 1:   Add 8 to each side.    6x = 2x - 24

Step 2:  Add 2x to each side.   8x = -24

Step 3:  Divide each side by 8.    x = -3

Answer is   -3      :)

Step-by-step explanation:

Answer:

x = - 6

Step-by-step explanation:

6x - 8 = 2x - 32

Move 2x to the left hand side of the equation

6x - 2x - 8 = - 32

4x - 8 = - 32

Move -8 to the right side of the equation

4x = - 32 + 8

4x = - 24

Divide both sides by 4

[tex] \frac{4x}{4} = - \frac{24}{4} \\ [/tex]

We have the final answer as

x = - 6

Hope this helps you

Step-by-step explanation:

If the distance is greater than the radius, the point lies outside. If it's equal to the radius, the point lies on the circle. And if it's less than the radius, you guessed it right, the point will lie inside the circle.

you install 412 feet of fencing along the perimeter of a rectangular yard. the width of the yard is 102 feet. what is the length of the yard?​

Answers

Answer:

Length = x feet = 104 feet

Step-by-step explanation:

Perimeter of a rectangle = 2(length + width)

Length = x feet

Width = 102 feet

Perimeter of a rectangle = 412 feet

Perimeter of a rectangle = 2(length + width)

412 = 2(x + 102)

412 = 2x + 204

412 - 204 = 2x

208 = 2x

x = 208/2

x = 104 feet
