Audrey needs to cut 1 meter of yellow ribbon and 28 centimeters of blue ribbon. In total, how many centimeters of ribbon does she need?

centimeters

Answers

Answer 1
she needs to cute 128 cm of ribbon because 1 m is equal to 100 cm and when you add 28 and 100 you get 128

Answer 2

Answer:  She needed 128 cm of ribbon.

Step-by-step explanation:

Since we have given that

Length of yellow ribbon needed to be cut = 1 meter

Length of blue ribbon needed to be cut = 28 cm

We need to find the number of centimeters she needed to be cut.

First of all, we convert meter into centimeter.

As we know that

1 meter = 100 centimeter

So, Total number of centimeters of ribbon she needed is given by

[tex]100+28\\\\=128\ cm[/tex]

Hence, She needed 128 cm of ribbon.

Which transformation rule maps ​ triangle ABC ​ onto triangle DEF ?



(x−7, y+3)

(x+3, y−7)

(x+7, y−3)

(x−3, y+7)

Answers

To find our solution, let us first take a point on one figure and match it with a point on the other figure. The easiest one is point C and point F. To get point C to point F, we first need to bring the x coordinate 7 units to the right, or, in other words, add 7. However, we are not yet at point F, as we need to decrease the y- value of point C by 3. Now, we are at point F. So, let's recap on what we did, we added the x by 7, and we subtracted the y value of point C by 3. 

We can turn this into words => (x + 7, y - 3).
Our answer is C) (x + 7, y - 3). Hope this helps and have a fantastic day!

Answer:  The correct option is (C) (x+7, y−3) .

Step-by-step explanation:  We are given to select the correct transformation rule that maps triangle ABC onto triangle DEF.

From the graph, we note that

the co-ordinates of the vertices of triangle ABC are A(-8, 6), B(-3, 6) and C(-7, 4).

And, the co-ordinates of the vertices of triangle DEF are D(-1, 3), E(4, 3) and F(0, 1).

The transformations from the vertices of triangle ABC to the vertices of triangle DEF are

A(-8, 6)   →   D(-1, 3) = D(-8+7, 6-3),

B(-3, 6)   →   E(4, 3) = E(-3+7, 6-3)

and

C(-7, 4)   →   F(0, 1) = F(-7+7, 4-3).

Therefore, the required transformation rule is given by

(x, y)  →  (x+7, y-3).

Thus, (C) is the correct option.

What is the score if total question is 85 and correct is 68?

Answers

You can find percentages like this by taking the total number of questions dividing it by 100 to find out how much each question was worth, then multiplying by the number correct.

So, 85 ÷ 100 ≈ 1.18

1.18 x 68 ≈ 80

So, the score was 80%.

1. An enclosed wooden crate is 4 feet tall, 8 feet long, and 6 feet wide. What is the total area of the top, bottom, front, back, and the left and right sides of the crate?

Answers

Final answer:

The total area of the top, bottom, front, back, and both sides of the crate is 208 square feet. This is calculated by finding the area of each pair of identical surfaces and summing these areas.

Explanation:

To calculate the total area of the top, bottom, front, back, and the left and right sides of a crate that is 4 feet tall, 8 feet long, and 6 feet wide, we need to find the area of each of these surfaces and sum them up. There are three pairs of identical surfaces on a rectangular crate.

The top and bottom surfaces each have an area of 8 feet (length) × 6 feet (width) = 48 square feet. So, for both the top and bottom together, the area is 48 square feet × 2 = 96 square feet.The front and back surfaces each have an area of 8 feet (length) × 4 feet (height) = 32 square feet. Therefore, the total area for both the front and back is 32 square feet × 2 = 64 square feet.The left and right sides each have an area of 6 feet (width) × 4 feet (height) = 24 square feet. So, the total area for both sides comes to 24 square feet × 2 = 48 square feet.

To find the total area of all these surfaces combined, we add these amounts together: 96 square feet + 64 square feet + 48 square feet = 208 square feet.

How to solve a system of equations using elimination

Answers

In order to use the elimination method, you have to create variables that have the same coefficient—then you can eliminate them. Multiply the top equation by 5. Next add theequations, and solve for y. Substitute y = 10 into one of the original equations to find x

To solve a system of equations by addition, also called elimination, the goal is to cancel out one of the variables by adding the equations together. However, in some cases, you will need to multiply one or both of the equations by a number in order to create a scenario where one of the variables will cancel out when the equations are added together. As long as you cancel a variable out, you will be able to add the equations together and solve for the variable. If you find one variable, you can find the other one easily.

What is the perimeter of triangle PQR? Show your work.

Answers

You know that the two triangles are congruent because two sides and one angle are congruent.

According to CPCTC, corresponding parts of congruent triangles are congruent, which means that PR and SU are equal.

3y-2=y+4
3y=y+6
2y=6
y=3

3(3)-2=9-2=7

7+4+6=17

The perimeter is 17 feet.

Hope this helps!

Answer:

PQR= 17 ft

Step-by-step explanation:

1. PQ ≅ ST = 4 ft (Given)

2. ∠PQR ≅ ∠STU (Given)

3. QR ≅ TU = 6 ft (Given)

Which makes the two triangles congruent by SAS postulate.

Now, from CPCTE, PR = SU

3y-2=y+4

Solve for y and simplify

Subtract Y from both sides.

Add 2 to both sides

3y-y=4+2

Add

2y=6

Divide both sides by 2

Y=3

Now, side PR is given by plugging in 3 for Y. PR = 3(3) - 2 = 9 - 2 = 7 ft. The perimeter of a triangle PQR is the sum of all of its sides. Perimeter = PQ + QR + PR = (4 + 6 + 7) ft = 17 ft. The perimeter of triangle PQR is 17 ft.

Your skateboard ramp is 2⅜ feet high. Your friend's skateboard ramp is 2²/5 high. Which skateboard ramp is higher?

Answers

So what you want to do here is get the fractions to have the same denominator.

To do this, you first want to get rid of the 2 from each number.

You can just subtract 2 from each because that won't truly impact the difference, except for if they were different, as in something like 3 2/5 and 4 2/5

So you're left with the fractions 3/8 and 2/5.

Now to get them to have the same denominator, you first find the LCM, or least common multiple. This can be found by just multiplying 8 and 5 together.

8 * 5 = 40

So what you can say is:

3/8 * 5/5 = ?

Since 5/5 = 1.

3/8 * 5/5 = 15/40

2/5 * 8/8 = 16/40

So if you compare the two fractions, you can tell that your friend's skateboard ramp is slightly higher.

Suppose point J has coordinate of -2 and JK=4. Then what is the possible coordinate(s) for K? 4 2 or -4 -4 2 or -6

Answers

Final answer:

Given that point J is at -2 and the distance between J and K is 4, the possible coordinates for K are -6 (if you count 4 steps to the left) or 2 (if counted to the right on the number line).

Explanation:

The given information tells us that point J has a coordinate of -2 and the distance JK equals 4. In a number line, distances can be counted to the left (negative direction) or to the right (positive direction). Therefore, point J will be 4 points to the left or right of, which means the coordinates for K could be -2-4 = -6 or -2+4 = 2.
