Step-by-step explanation:

GCF is greatest common factor. It is also termed as HCF.

Firstly we write the factors of 120 and 84

120 = 2×2×3×5×2

84 = 2×2×3×7

HCF of 120 and 84 = 12

ATQ,

Tasha believes that she can rewrite the difference 120 − 84 as a product of the GCF of the two numbers and another difference. Let's try to write like this.

120-84 = (12×10-12×7)  [using the distributive property]

= 12(10-7)

It means that the difference 120 − 84 as a product of the GCF (i.e. 12) of the two numbers and another difference (i.e. 10-7). Hence, she is correct.

The time it will take the second crocodile to finish its snack is 120 seconds

Let x represent the rate of the first crocodile and let y represent the rate of the second crocodile.

The two crocodiles working together can finish a snack in 40 seconds. Thus;

(1/x + 1/y)40 = 1

It takes one of the crocodiles 60 seconds to finish its snack. Thus;

(1/x + 1/60)40 = 1

40/x + 2/3 = 1

x = 120 seconds

Answer:

59 percent

Step-by-step explanation:

59 divided by 100 is 0.59, which means 59 percent.

Also, when the total is 100, then the amount out of 100 is the percent ( 59 out of 100 is 59 percent, because it is out of 100).

Answer:

x = 10 , EF = 8 , FG = 15.

Step-by-step explanation:

Given : If EF = 2x – 12, FG = 3x – 15, and EG = 23.

To find :  find the values of x, EF, and FG.

Solution : We have given EF = 2x – 12, FG = 3x – 15, and EG = 23.

Let the line E ___F___G.

Here F is the mid point of EG . ( mid point divide the line EG cut the line EG in two equal parts)

We can say EF = FG.

EF + FG = EG -------(1)

Plug tha values EF = 2x -12  and FG = 3x - 15 , EG = 23 in equation (1).

2x - 12 + 3x -15 = 23 .

On combine like terms

2x + 3x -12 -15 = 23 .

5x - 27 + 23 .

on adding both side by 27.

5x = 23 +27.

5x = 50 .

On dividing both sides by 5.

x = 10.

Them, EF = 2 (10) -12

                  20 -12

             EF = 8

FG = 3 (10) -15 .

FG = 30 -15 .

FG = 15.

EG = 5 +18 = 23 .

Therefore, x = 10 , EF = 8 , FG = 15.

Answer:

one Bush costs $19 and one geranium costs $6

Step-by-step explanation:

Let the cost of one Bush be x

Let the cost of one geranium be y

If Heather spent $50 on 2 rose bushes and 3 geraniums, then the equation that represent the statement is:

2x+3y = 50….... 1

If amanda spent $186 on 6 rose bushes and 12 geraniums, then the equation representation will be:

6x+12y = 186…......2

Solve equations 1 and 2 simultaneously

2x+3y = 56..... 1 × 3

6x+12y = 186 ..... 2 × 1

.......…............

6x+9y = 168

6x+12y = 186

Subtract

9y - 12y = 168-186

-3y = -18

y = -18/-3

y = 6

Substitute y = 6 into equation 1:

2x+3y = 56

2x+3(6) = 56

2x+18 = 56

2x = 56-18

2x = 38

x = 38/2

x = 19

Hence one Bush costs $19 and one geranium costs $6

NB: note that the y rose bushes in the question was corrected and 6 rose bushes was used instead in the equation.

Answer: Part A - C, Part B - 12 pieces

Step-by-step explanation:

Part A:

We know that 1/4 of Meredith's sub is bigger than 1/4 of Jim's sub, so we can set up an inequality.

Let Meredith's sub size = m; Jim's = j

Therefore, 1/4*m > 1/4*j

We can multiply both sides by 4:

m > j

Thus, the correct answer is C

Part B:

Since he had 1/4 of it left, that means he at 1 - 1/4 of it = 3/4 of his sub.

We can calculate the value of 3/4 * 16 = 12 pieces

Explanation:

Start at 8 and count down by 1 until three slots are filled.

There are 8*7*6 = 336 different permutations.

Alternatively, you can use the nPr permutation formula with n = 8 and r = 3.

Step-by-step explanation

Jasmine's grandma's home will be 504 miles away from her home

The relation between distance[x] and time [t] is -

[x] = v [t]

where v is the velocity of body.

Given is Jasmine reached her grandma's house in 45 minutes. When she was biking back home in the evening it was foggy and she went 4 mph slower. The trip back took her 1 hour and 10 minutes.

Let her grandma's home be [x] miles away form her house.

Assume that her velocity was [v] mph on her way to grandma's house.

45 = x/v

x = 45v

Her velocity on her way back home would be [v - 4] mph

70 = x/(v - 4)

x = 70(v - 4)

Equating both -

45v = 70(v - 4)

45v = 70v - 280

70v - 45v = 280

25v = 280

v = 11.2 mph

The value of [x] will be -

x = 45 x 11.2 = 504 miles

Therefore, Jasmine's grandma's home will be 504 miles away from her home

Answer:

Infinitely many solutions

Step-by-step explanation:

Given the system:

[tex]\left \{ {{x+2y=0} \atop {10y=-5x}} \right.[/tex]

One way to do it is to use substitution. That means we want to isolate one of the variables in one equation so we can plug it into the other equation. We can isolate [tex]x[/tex] in the first equation by subtracting [tex]2y[/tex] from both sides.

[tex]\left \{ {{x=-2y} \atop {10y=-5x}} \right.[/tex]

Now we know what [tex]x[/tex] is, so we can plug it into the bottom equation.

[tex]10y=-5(-2y)[/tex]

Then we simplify the right side:

[tex]10y=10y[/tex]

Then we divide both sides by 10:

[tex]y=y[/tex]

Since [tex]y[/tex] will ALWAYS be equivalent to itself, no matter what, we know that there are infinitely many solutions.

Answer:

A notation that correctly describes the given transformation is:

[tex]R_{O, 90\°}, r_{x-axis}[/tex]

A rotation of 90° around the origin, followed by a reflection over the x-axis.

Here you can see that we have a rectangle in the first quadrant, and then it is moved to the third quadrant.

In the image, you can also see that the orientation of the rectangle changes, thus, we have a type of rotation.

A rotation from the first quadrant to the second quadrant would give use the desired orientation of the rectangle, and then we could reflect it over the x-axis to reach the third quadrant, so we can write the transformation as a rotation over the origin of 90° followed by a reflection over the x-axis.

I'm not sure of the notation you use in the options, but this would be written as:

[tex]R_{O, 90\°}, r_{x-axis}[/tex]

That is a rotation of 90° around the origin followed by a reflection over the x-axis.

Step-by-step explanation:

The second wedge has a greater volume and it is greater by 4.125 in³.

Since the each cheese wedge has a triangular base, its volume V = 1/2bhw where

Given that for the first wedge, b = 2.5 in, h = 4.5 in and w = 3 in, its volume V' = 1/2bhw

= 1/2 × 2.5 in × 4.5 in × 3 in

= 33.75 in³/2

= 16.875 in³

Given that for the second wedge, b = 3 in, h = 4 in and w = 3.5 in, its volume V" = 1/2bhw

= 1/2 × 3 in × 4 in × 3.5 in

= 42 in³/2

= 21 in³

Since V" = 21 in³ > V' = 16.875 in³, the second wedge has a greater volume.

The amount its is greater than the first volume is the difference in their volumes. V" - V' = 21 in³ - 16.875 in³

= 4.125 in³

The second wedge has a greater volume and it is greater by 4.125 in³.
