Answer:

Step-by-step explanation:

To boil rice you use the following ratio

Water : Rice

3 : 1

? : 8

Basically what the ratio 3:1 means is that for every 3 cups of water, you need 1 cup if rice.

6 cups of water, you need 2 cups of rice (6:2)

9 cups of water, 3 cups of rice (9:3)

Etc.

All you would have to do is multiply 3 by 8 to find out how much water she needs for 3 cups of rice :)

Answer:

ok the ratio of water to Rice is 3:1 meaning water is 3 rice is one and your child that we have 8 cups of rice so really quite the ratio of rice to the number of cups of rice so it will be if one is equals to 8 what about 3 that is the ratio that represents water so we'll cross multiply so that you have 3 * 8/1 and the answer is 24 so the number of cups of water needed is 24

Answer: I think is 420 miles in 7 hours

hope this helps :D

Step-by-step explanation:

Answer:

A train would cover 180 miles in 3 hours, So in 6 hours it will cover 360 miles, in 7 hours it will cover 420 miles.

Step-by-step explanation:

150 miles → 2 1/2 hours = 150 minutes

x miles     → 3 hours = 180 minutes

(150 × 180) ÷ 150 = x miles

27,000 ÷ 150 = x miles

180 = x miles

a geometric transformation would mean to make some changes in any given geometric shape. In geometry, transformations relate to the movement of figures on a plane. Each transformation follow a rule

Step-by-step explanation:

For example 4 to the felt and 3 to the top, (x,y) (x-4, y+3)

2 down and 4 to the right, (x.y) (x-2, y+4)

Basically if you see an image on a graph, its the preimage and you need to create the new image the same size and shape as the the original.  

Answer:

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(82, −96) and (87, −86)

We have

[tex]m = \frac{ - 86 - - 96}{87 - 82} = \frac{ - 86 + 96}{5} = \frac{10}{5} = 2 \\ [/tex]

Answer:

30

Step-by-step explanation:

Original Equation: 2(7 + 8)

So you have to multiply 2 by 7 which equals 14

Then you multiply 2 by 8 which equals 16

Your equation should now look like this: 14 + 16

Add 14 and 16 together.

Your answer is 30

Answer:

∆FSH ≅ △_____

By rule Cannot Be Determined

Step-by-step explanation:

Both do not have an answer.

Answer:

M²

Step-by-step explanation:

Parallel lines have equal slopes.

One line has a slope of M then the line parallel to it has a slope of M , thus

product of slopes = M × M = M²

The the product of their slopes is M².

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

two lines are parallel

and the slope of one of the lines is M

Also, the parallel lines have the same slope.

So, both the line lines have slope M.

Now, the the product of their slopes

= M x M

= M²

Hence, the product of their slopes is M².

Answer:

[tex]y=-\frac{1}{2} x+2[/tex]

Step-by-step explanation:

The given equation is written in slope-intercept form:

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

where:

The slope is 2:

When two lines are perpendicular, their slopes will be opposite reciprocals. Find the slope of the line perpendicular to the given equation:

[tex]m_{1}=2[/tex]

This can be seen as:

[tex]m_{1}=\frac{2}{1}[/tex]

Flip the fraction (reciprocal):

[tex]\frac{2}{1}[/tex] → [tex]\frac{1}{2}[/tex]

Now find the opposite:

[tex]\frac{1}{2}[/tex] → [tex]-\frac{1}{2}[/tex]

So the slope of the perpendicular line is:

[tex]m_{2}=-\frac{1}{2}[/tex]

Now make an equation written in point-slope form:

[tex]y-y_{1}=m(x-x_{1})[/tex]

where:

Insert information:

[tex]y-3=-\frac{1}{2} (x-(-2))\\\\y-3=-\frac{1}{2} (x+2)[/tex]

Simplify to slope-intercept form. Solve for y:

Use the distributive property:

[tex]y-3=-\frac{1}{2}(x)-\frac{1}{2} (2)\\\\ y-3=-\frac{1}{2} x-1[/tex]

Add 3 to both sides to isolate the variable:

[tex]y-3+3=-\frac{1}{2} x-1+3\\\\y=-\frac{1}{2} x+2[/tex]

Answer:

-45

Step-by-step explanation:

Sum of two integers = -30

one of them = 15

let another number be 'x'

x + 15 = -30

x = -30 - 15

x = -45

so the other number is -45
