IM GIVING BRAINLEST!!!!!! Francesca bought a box of yo-yos so she could add them to her birthday party goodie bags. After putting one yo-yo in each of 19 goodie bags, there were 19 yo-yos left in the box.
Let y represent how many yo-yos were in the box to start. Which equation models the problem?

Answer:

Improper Fraction :101/2

Mixed Fraction : 50 1/2

Step-by-step explanation:

101/2 is already an Improper Fraction However to get the Mixed Fraction is to divide the 100 by 2 to get 50 and that is how you get the mixed fraction (50 is the whole to the mixed fraction)

Answer:

2-4--2

Step-by-step explanation:

Answer:

An example of scale factoring that could be used in everyday life is when modeling. When modeling and object you don't make it, for example, 10 feet because that cannot fit on a computer screen. So when on a computer you see a much smaller-scale version.

Here is my process for solving this.

First I drew arrows that indicated I was moving the whole triangle 5 units to the left.

*Look at first attachment*

Then I drew another triangle using those new points. (The new triangle is in pink)

*Look at second attachment*

Then I drew arrows that moved this new triangle 4 units up. (The new arrows are in pink)

*Look at third attachment*

Then I drew the new triangle in blue using the new points.

*Look at fourth attachment*

Then I mirrored / reflected the triangle over the x axis (the horizontal line) In green.

*Look at fifth attachment*

The fifth attachment in green is the final product! Hope that helps.

Answer:

m = -45

Step-by-step explanation:

-16 - m = 29

Add 16 on both sides.

-m = 45

Make the m positive by multiplying with -1.

m = -45

Answer:

m=-45 This is answer trust me

Answer:

4 terms

Step-by-step explanation:

There are 4 terms in the given expression:

=> 55

=> 14n

=> -2m

=> 3p

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer:

5.6 : 2.4

Step-by-step explanation:

Answer: 23.04

Step-by-step explanation:

2.0*2.0= 4.0

2.4*2.4= 5.76

4.0*5.76= 23.04

Answer: The area of the given shape is 9.734 meter square

Step-by-step explanation:

The given shape is a square with 4 sides of equal dimensions "a",

Area of Square = Square of its side "a"

Here, a = Hypotenuse of the inner triangle

Step 1: Get the hypotenuse value of the inner right triangle as the base and height dimensions of the right triangle is given.

Step 2: By using Pythagoras theorem,

Square of the base + Square of the height = square of the Hypotenuse

(2.4)^2 + (2.0)^2 = 9.76

Therefore the value of the hypotenuse = 3.12m

The area of the square = 9.734 meter square.

Answer:

8    

16

26  are the first three terms

Step-by-step explanation:

T1 = 1^2 + 5(1) + 2 = 8

T2 = 2^2 + 5(2) + 2 = 16

T3 = 3^2 + 5(3) + 2 = 26

Answer:

10.7 = 0

Step-by-step explanation:

8 - 4.7*y - x

8 - 4.7*y - x = 0

8 - 4.7*(-1) - 2 = 0

8 + 4.7 - 2 = 0

10.7 = 0

Answer:

Step-by-step explanation:

First, we can figure out how many additional inches of rope are needed.  If there are 8 knots, 16 additional inches will be needed. Peter would need 9 feet 4 inches of rope, or 112 inches.

The formula for finding the length of the rope needed would be 8+2n.

Hope this helps!

Answer:

112 inches

Step-by-step explanation:

Each knot needs 2 inches of rope

There are 2 knots

2*8 = 16 inches

He wants 8 ft from the ground, but he wants it in inches

8 ft* 12 inches per foot = 96 inches for the rope

96+ 16 =112 inches of rope

Answer:

D, she DID NOT make an error

This is a trick question.

Step-by-step explanation:

Work Shown:

V = lwh

V = 10.4*5*8

V = 416

Explanation: We multiply the length, width, and height to get the volume of the block. The units for the volume are in cubic millimeters which can be written as "cubic mm" or \(\text{mm}^3\) to mean that we're cubing all of "mm", and not just a single m.

I guess you could say  \((\text{mm})^3\) to be very clear that both "m"s are being cubed, though this convention isn't something I've seen a lot.

Answer:-8-5=-13, and i don't understand the second part

Step-by-step explanation:

if you think about a number line, adding negative 5 to negative 8 will only bring it "more negative"

same signs, add and keep the signs. different sign subtract, then keep the sign of the bigger number.

Answer:

D

Step-by-step explanation:

Lets go through each answer choice and check if it is correct.

A: False. 50% of 70 is not 31.

B: False. 17% of 70 is not 17.

Answer:

The answer is D, On average, 2 out of 10 adults visited the museum most frequently.

Step-by-step explanation:

You can find this out by finding out how many adults there was total. You would do 31+14+17+8=70 and the you can see that 14 went to the museum so it would be 14/70. This fraction simplifies to 2/10.
