How many times does 50 go in to 275

1. 50

2. 100

3. 150

4. 200

5. 250

and to get 275 you add half of 50 which is 25

Answer:

5 hours and 30 minutes.

Step-by-step explanation:

5x50=250

remainder 25

half of an hour is 30 mins and half of 50 is 25.

therefore; add the 5h and 30m to get 5h30m

Answer:

x=1160 HAVE A GREAT DAY!!! :D

Step-by-step explanation:

Okay! So, first you would set up a proportion

x/1740=2/3

Then you cross multiply

3x=3480

After that, you divide both sides of the equation by 3

x=1160

Answer:

For answer a,

the equation is -1 - 5

this equals -6

From -1 to -6 is 5

A.) The difference is 5

For answer b,

the equation is  -7 - (-3)

There are two minus signs by the -3 so that means to turn those two signs into a plus sign

- 7 + 3

Start at -7 and move to the right 3

You will end up at -4

B.) The difference is 3

Answer:

I'm going to say the square roo of 36

Step-by-step explanation:

If you think about it the square root of 36 is 6

the square root of 21 is 4.582

1/5 is 0.2

and 2/3 is 0.66

so with that information you can conclude that the square root of 36 has a higher value than the other numbers

Answer:

(4,5)

Step-by-step explanation:

I solved through substitution

3x+2y=22

x-2y=-6 ----> -2y=-6-x ----> -2y=-x-6 -----> y=1/2x+3

Solving for x:

3x+2y=22

3x+2(1/2x+3)=22

3x+x+6=22

4x+6=22

4x=16

x=4

Solving for y:

x-2y=-6

4-2y=-6

-2y=-10

y=5

Answer:

Step-by-step explanation:

Answer:

The equation of the line is y = (5/2)x + 5.

Step-by-step explanation:

When both line are parallel, they share the same gradient value so the equation will be y = (5/2)x + b. Next, you have to find the value of b, by substituting the coordinates into the equation :

y = (5/2)x + b

let x = -2, y = 0,

0 = (5/2)(-2) + b

0 = -5 + b

b = 5

Answer:

y=5/2x+5

Step-by-step explanation:

Since both lines are parallel they have the same slope. From y=5/2x+1, the slope is 5/2

The equation of the line passing through (-2,0) using slope intercept form is

y-y1=m(x-x1)

y-0=5/2(x--2)

y=5/2(x+2)

y=5/2x+5

Answer:

Im not sure how you are supposed to answer this but they are similar by side angle side

Step-by-step explanation:

We are given that NO/OQ=PO/OM

This tells us that the sides are in a ratio.

We also know that angle NOM is equal to angle POQ

Now we have 2 sides and 1 angle thus they are similar by side angle side

The height of cone is 7 m

A cone is a three-dimensional shape, formed by using a set of line segments or the lines which connect at a common point, to all the points of a circular base.

The cone height formula helps in calculating the distance from the vertex of the cone to the cone's base. The height of the cone can be calculated using either the volume of cube and radius or with slant height and radius of the cone.

Formula 1: h = 3V/πr2

where,

V = Volume of the cone

r = Radius of the cone

This formula is derived from the formula of the volume of a cone.

Given:

d= 12 m

Volume = 264 m.

volume = πr²h

264= 1/3x6x6x3.14 * h

264 = 37.68 * h

h= 264  / 37.68

h= 7 m

Answer:

y=3/7x+46/7

Step-by-step explanation:

Parallel lines have the same slope. This means in the equation y=mx+b, m=3/7 for sure. Then, it gives us the point (1,7). The line has to go through this point so we plug it in: 7=3/7(1)+C. Then, we solve for C using algebra.

7-3/7=C

C=46/7

  The sequence 18

Step-by-step explanation:

After Nolan brings down a zero, the dividend Nolan will be 20, the same one he started with. So, he will get the same result he has gotten so far: the first quotient digit is 1 and the second quotient digit is 8, resulting in a new dividend of 20 (after the 0 is brought down).

The digits 18 will repeat until Nolan gets tired.

Answer:

The width is 10 inches

The length is 30 inches

Step-by-step explanation:

Perimeter of a Rectangle

The perimeter of a rectangle of length L and width W is calculated as follows:

P = 2L + 2W

It's given the length of a rectangle is 10 more than twice the width:

L = 2W + 10

Substituting into the formula of the perimeter:

P = 2(2W + 10) + 2W

Operating:

P = 4W + 20 + 2W

P = 6W + 20

It's given this perimeter is 80 inches, thus

6W + 20 = 80

Subtracting 20:

6W = 80 - 20 = 60

Dividing by 6:

W = 60 /6 = 10

Since :

L = 2W + 10

L = 2*10 + 10

L = 30

The width is 10 inches

The length is 30 inches

2y² - 5y + 2

Step-by-step explanation:

Original equation:

2y² - 9y - 2 + 4(y + 1) =​

Use distributive property

4 · y = 4y

4 · 1 = 4

Plug these values back into the equation:

2y² - 9y - 2 + 4y + 4 = ?

Combine like terms

2y² - 5y - 2 + 4

for the two of them, the first answer is the answer

Answer:

#1 - First option: y + 7 =  [tex]\frac{-1}{4}[/tex](x -4)

#2 - First option: y = 2x - 5

Step-by-step explanation:

#1

Given: (x1,y1) = (4,-7) and m = [tex]\frac{-1}{4}[/tex];

To find the point slope form which is

y - y1 = m(x - x1); substitute (x1,y1) and m

y - (-7) = [tex]\frac{-1}{4}[/tex](x -4)

y + 7 =  [tex]\frac{-1}{4}[/tex](x -4)

#2

Given: points (x1,y1) = (0, -5) and (x2,y2)=(4,3)

To find the slope we use

m = [tex]\frac{(y2-y1)}{(x2-x1)}[/tex] = [tex]\frac{(3-(-5))}{(4-0)}[/tex] = [tex]\frac{8}{4}[/tex] = 2

Now pick a number to find b

y = mx + b

y1 = mx1 + b

-5 = 2(0) + b

b = -5

now plug into y = mx + b; which is

y = 2x - 5
