The depth of snow melting on a sidewalk changes over time. The equation below represents
the depth (d) in inch(es) as time (t) passes. How many inches deep is the snow just before
it begins to melt?

Answer:

Since the corresponding sides of similar triangles are proportional,

[tex]\frac{a}{b}= \frac{2.1}{1.4} =\frac{3}{2}[/tex]

Answer:

B

Step-by-step explanation:

From the given information:

Sienna has $8 denotes the unit blocks of x tiles. So, she saved $3 per week.

This implies that:

8x + 3(1) = 8x + 3

Also,

If Jacob as well had $6 which implies 6x unit block of tiles while he saved $4;

i.e.

6(x) + 4(1) = 6x + 4

So;

the model that can determine when Sienna will have the same amount as Jacob is:

8x + 3 = 6x + 4

x - 1.6

Step-by-step explanation:

Answer:

the answer is X=1

Step-by-step explanation:

-0.50x and +1.5x are like terms

-5 and 3.4 and like terms

so -0.50x + 1.5x equals 1

and -5 + 3.4 equal -1.6

Correct answer: Choice a.

Step-by-step explanation:

Reflections In The Coordinate Plane

Reflect over the x-axis:

When we reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is mapped to its opposite (its sign is changed).

The reflection of the point (x,y) across the x-axis is the point (x,-y).

Reflect over the y-axis:

When reflecting a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is mapped to its opposite (its sign is changed).

The reflection of the point (x,y) across the y-axis is the point (-x,y).

Note that the original triangle drawn by Jack and the image triangle have the same y-coordinate, but the inverse of the x-coordinate. This matches the definition of a reflection over the y-axis.

Correct answer: Choice a.

Answer/ explaination

the answer is 108, not 180 because 9 goes into 7, 0 times but he put 8

Answer:

-4 is the slope

Step-by-step explanation:

Because the line is going downwards that makes it a negative and if you count the boxes rise over run. You look for the point where the line meets a box perfectly and then you count the boxes down which is 4 and across which is one which makes it -4/1. So the slope is -4.

Step-by-step explanation:

The trick here is finding the scale used in the plotting. From the question, we can find two hints;

- Number of cat = 40. Since it has an equal scale for both men and women. It means the 40 / 2 = 20 (20 men and 20 women) has cat as their favorite pet.

- Since we know that the number of men is 20, we have to find what individual box represents. There are 4 boxes, this means each box would have  a value of 20 / 4 = 5

Dog

For men, there are basically 5 lines (or boxes, if you prefer). This means 5 * 5 = 25

For women, there are basically 6 lines (or boxes, if you prefer). This means 6 * 5 = 30

Total frequency = 30 + 25 = 55

Hamster

For men, there are basically 3 lines (or boxes, if you prefer). This means 3 * 5 = 15

For women, there is basically 1 line (or box, if you prefer). This means 1 * 5 = 5

Total frequency = 15 + 5 = 20

Other

For men, there are basically 2 lines (or boxes, if you prefer). This means 2 * 5 = 10

For women, there are basically 3 lines (or boxes, if you prefer). This means 3 * 5 = 15

Total frequency = 10 + 15 = 25

Answer:

basically y=mx+b so it's y=1(3)+4

y = 3/2 or 1.5 (IF THE ANGLE IS 30 BY THE RATIOS OF A RIGHT TRIANGLE.)

hope it's right

Step-by-step explanation:

FOR X:

Let's solve your equation step-by-step.

4x+3=31

Step 1: Subtract 3 from both sides.

4x+3−3=31−3

4x=28

Step 2: Divide both sides by 4.

4x/4=28/4

x=7

FOR Y:

Step 1: Simplify both sides of the equation.

(3)(7)+6y=30

21+6y=30

6y+21=30

Step 2: Subtract 21 from both sides.

6y+21−21=30−21

6y=9

Step 3: Divide both sides by 6.

6y/6=9/6

y=3/2

Answer:

755

Step-by-step explanation:

First do 180x7 which will give you 1,260 then do 1,260-375-137 which gives you 755.

Kate has the $748 of money.

Subtraction is a mathematic operation. Which is used to remove terms or objects in an expression.

Given:

Over the summer,

Kate earned $180 each week for 7 weeks.

That means,

she earns = 180 x 7

= $1260

She spends,

= 375 + 137

= $512

Now, she has the money = $1260 - $512

= $748

Therefore, she has the money $748.
