Answer:

7,560

Step-by-step explanation:

70% of 1750 × 6 = 7,560

For a rotation of 180° clockwise or counterclockwise, the x and y will always be the opposite. For instance, if coordinates (4, 7) are being 180° rotated, the new set of coordinates will be (-4, -7).

Remembering the rule, the final answer to your question is A, 180° clockwise rotation about the origin.

Answer:

33

Step-by-step explanation:

From what we know in April and May combined Joe has collected 61 stamps (27+34=61). To then work out how many Joe collected in June you would take the 61 we know he has already got away from the grand total of 94 (94-61=33) this means in June he collects 33 stamps. Hope this helps :)

Answer:

√250 + 2 = 5√10 + 2

Step-by-step explanation:

1. refer to image attached

2. split the area into a rectangle and triangle (see red line)

3. find the area of the triangle

a. find the base (2)

b. find the height (2)

area = base * height / 2 = 2 * 2 / 2 = 2

4. find the area of the rectangle

a. find the width

the width can be found from the right triangle at the top right. the height is 2 and the bottom leg is 1, so using the pythagorean theorem, the hypotenuse, which is the width of the triangle, equals

√(2²+1²)  = √5 as our width

b. find the length

given the top right triangle, we have a height of 5 and another leg length of 5, so the length = √(5²+5²) = √50

the area of the rectangle is thus √50 * √5 = √250

4. the area is thus the two areas added up, or √250 + 2

Answer:

9.16

Step-by-step explanation:

350 = 12 (x + 20)

350 = 12x +240

350 = 12x +240

-240           -240

110 = 12x

9.16 or 9.17 = x

Answer:

y = -5x + 12

Step-by-step explanation:

First remember the equation y = mx + b

We have values for x, y, and m so all we need to do is solve for b.

2 = -5 (2) + b

2 = -10 + b

12 = b

Then plug that value back in and keep the variables for x and y

y = -5x + 12

The total number of children in Stephan's school prefer pepperoni pizza where 375 children in Stephan's school is 310.

Equivalent ratio is the ratio which is same in the value as the original ratio, but the numerator and denominator is different for both the ratios.

Stephan read that 62 out of every 75 children prefer pepperoni pizza. Thus, the ratio of children who prefer pepperoni pizza to the total children is,

[tex]n=\dfrac{62}{75}\\[/tex]

Let suppose there are x children in Stephan's school prefer pepperoni pizza. There are 375 children in Stephan's school. The ratio of children who prefer pepperoni pizza to total 375 children is,

[tex]\dfrac{x}{375}[/tex]

Both the above ratio are for the same condition, and are equivalent ratio. Thus,

[tex]\dfrac{x}{375}=\dfrac{62}{75}\\x=\dfrac{62}{75}\times375\\x=310[/tex]

Thus, the total number of children in Stephan's school prefer pepperoni pizza where 375 children in Stephan's school is 310.

Answer:

54

Step-by-step explanation:

( - 3 )³

= ( - 3 ) x ( - 3 ) x ( - 3 )

= - 27

( 5 - 2 )^4

= 3^4

= 3 x 3 x 3 x 3

= 81

( - 3 )³ + ( 5 - 2 )^4

= - 27 + 81

Answer:

its has to be 45.6 becuase when you calculate you get 45.66666667 so its either that or 46

Step-by-step explanation:

add 75+1+80+5+85+7+90+3+95+1+100+6=548

then you divide by the amount of numbers there are which is twelve so

548 divided by 12 is 45

Answer:

4

Step-by-step explanation:

So, 5/15 shirts are gray.

This can be simplified to 1/3. (5÷5 = 1, 15÷5=3)

So taking this data into account, if we have 12 shirts, one third of them should be gray. So, 12/3 = 4.

Answer:

(-1,5)

(0,7)

(1,9)

(2,11)

(3,13)

(4,15)

(5,17)

Step-by-step explanation:

Because we are already given our slope and a point to help us create our line. With this information, we can find the other points that we would use to create the line for a slope = 2 passing through the point (-1, 5).

To do so we use the information that is a slope equal  [tex]m=\frac{rise}{run}[/tex]

So we make our slope which is two look like [tex]m=\frac{2}{1}[/tex]

So to find our next point we would have to rise up 2 units and run 1 unit to the right from (-1, 5). We do the same to find the next points.

We get the following points from doing so  

(0,7)

(1,9)

(2,11)

(3,13)

(4,15)

(5,17)

You will use the points to create the line for the slope 2 passing through the point (-1, 5)

Answer: 4x-15y+15

Step-by-step explanation:

Just combine then simplify.

PLEASE MARK ME THE BRAINLIEST!!!

Answer:

4x - 15y + 15

Step-by-step explanation:

You can only combine terms that have the same variable. For example, a number with the "x" variable can only be added to/subtracted by other numbers with the "x" variable. To make the simplifying easier, I would start by putting these terms next to each other. Remember that the negative values must stay with the value they are next to (i.e., the (-) in front of the (7y) must stay with it).

Starting: -2x + 3 - 8y + 12 + 6x - 7y

Rearranged: -2x + 6x - 8y - 7y + 3 + 12

Then, combine the values by adding them. Remember, adding a negative value means you end up subtracting it.

(-2x) and (6x) combine to form (4x)

(-8y) and (-7y) combine to form (-15y)

(3) and (12) combine to form (15)

This leaves you with:  4x - 15y + 15

Answer:

40 tables total

Step-by-step explanation:

Several ways to figure it out, but hopefully one of these is better for you to understand..

20 is half of 40 or 50% 50% in decimal form is .5 or .50 (either way works)

40 x .5 = 20 or you could say

1/2 of 40 is 20

So you would want to shade 20 tables, and the other 20 would be unshaded.

Look at the graph picture I attached

[tex]y = mx + c[/tex]

c is the intercept, which is why the graph crosses the y-axis at +3

to find where it crosses the x-axis, we make y = 0

[tex]y = 0\\\to -\frac{2}{3}x + 3 = 0\\-\frac{2}{3} = -3\\\frac{2}{3}x = 3\\2x = 9\\x = \frac{9}{2}\ \ (=4.5)[/tex]
