Find the value of x

Answer:

10 %

Step-by-step explanation:

let the percent be x

according to the question

7.8 = x % 0f 78

7.8 = x /100 * 78

7.8*100 = 78x

780 = 78x

780/78 = x

10 = x

Answer:

10 percent

Step-by-step explanation:

7.8 is ? of the number 78.

So, we will multiply 7.8 by 100.

7.8 x 100 = 780

Now, we will divide 780 by 78.

780/78 = 10

So, our answer is 10.

Or, you can divide:

78 divided by 7.8 is 10

Given:

The expressions are:

[tex]2x(x^2-6x+3)[/tex]

[tex]2a^2(5b^2+3ab+6a+1)[/tex]

To find:

The product of each expression.

Solution:

According to the distributive property of multiplication over addition, we get

[tex]a(b+c)=ab+ac[/tex]

The first expression is:

[tex]2x(x^2-6x+3)[/tex]

Using distributive property of multiplication over addition, we get

[tex]2x(x^2-6x+3)=(2x)(x^2)+(2x)(-6x)+(2x)(3)[/tex]

[tex]2x(x^2-6x+3)=2x^3-12x^2+6x[/tex]

Therefore, the product of [tex]2x(x^2-6x+3)[/tex] is [tex]2x^3-12x^2+6x[/tex].

The second expression is:

[tex]2a^2(5b^2+3ab+6a+1)[/tex]

Using distributive property of multiplication over addition, we get

[tex]2a^2(5b^2+3ab+6a+1)=(2a^2)(5b^2)+(2a^2)(3ab)+(2a^2)(6a)+(2a^2)(1)[/tex]

[tex]2a^2(5b^2+3ab+6a+1)=10a^2b^2+6a^3b+12a^3+2a^2[/tex]

Therefore, the product of [tex]2a^2(5b^2+3ab+6a+1)[/tex] is [tex]10a^2b^2+6a^3b+12a^3+2a^2[/tex].

OPTION D

Answer:

a=28/5 or 5.6

Step-by-step explanation:

2a/7=a-4

Multiple both sides of the equation by 7

2a=7a-28

Subtract 7a from both side

2a-7a=-28

Like Term

-5a=-26

Divide -5 from both side

a= 5.6

Answer:

y = 0

Step-by-step explanation:

Let's use the addition method.

2x + y - 10 = 0

x - y - 5 = 0

Write the first equation as is. Write below it the second equation multiplied by -2 on both sides. Then add the equations.

         2x + y - 10 = 0

(+)     -2x + 2y + 10 = 0

--------------------------------

                 3y        = 0

Divide both sides by 3.

y = 0

Answer: y = 0

Answer:

See explanation below

Step-by-step explanation:

Flat fee = $25

Cost per mile = $0.60

Let

C = total cost

m = number of miles travelled by the truck

The equation is

C = 25 + 0.60m

The independent variable is miles,m travelled

The dependent variable is total cost, C

$25 is the constant

Answer:

[tex]\text{Domain: }\{-6, -3, -1, 5\}\\\text{Range: }\{-4, 0, 2, 5\}[/tex]

Step-by-step explanation:

The domain of a function represents the range of x-values that the function has. The range of a function represents the range of y-values that the function has.

Coordinates are written as (x, y). Thus, the domain of these ordered pairs include the x-values of each ordered pair. Similarly, the range of these ordered pairs include the y-values of each ordered pair. Therefore, we have:

[tex]\text{Domain: }\{-6, -3, -1, 5\}\\\text{Range: }\{-4, 0, 2, 5\}[/tex]

Answer:

Step-by-step explanation:

126 + 44 = 170 ( total for under 25s)

186 - 56 = 130 (online for 25s - 50s)

154 - 58 = 96 ( in stores for aboves 50s)

314 for ONLINE TOTAL

196 for IN STORES TOTAL

510 for TOTAL TOTAL

A = 170

B = 56

C = 96

D = 96 - 58 = 38

E = 314 - 196 = 118

F = 510

Remove the unnecessary parantheses and rewrite

3 m ² + 5 m - 2 - 2 m + 18

combine like terms

3m² + 5 m - 2 m + 18 - 2

calculate the sum

3m² + 3 m + 16

Answer:

4.5 miles per hour

Step-by-step explanation:

Selma uses a jogging trail that runs through a park near her home. The trail is a loop that is 3/4 of a mile long. On Monday, Selma ran the loop in 1/6 of an hour. What is Selma's unit rate in miles per hour for Monday's run?

Distance = 3/4 of a mile

Time taken on Monday = 1/6 of an hour.

What is Selma's unit rate in miles per hour for Monday's run?

Unit rate in miles per hour for Monday's run = distance ÷ time taken

= 3/4 ÷ 1/6

= 3/4 × 6/1

= (3 * 6) / (4 * 1)

= 18/4

= 4.5 miles per hour

Unit rate in miles per hour for Monday's run = 4.5 miles per hour

Answer:

The shape is translated four units left, and 2 units up, therefore the answer would be x=-4 and y=+2

Answer:

P= (1,-1)= P'= (-3,1)

T=(4,-1)=T'= (0,1)

R=(5,1)=R'= (1,3)

A= (5,3)=A'= (1,5)

So you would move the points 4 units across (left) and 2 units up (2,-4)

I would think your answer is right, it would be the second choice. Its just a little hard to determine because you would use the method of moving the point but to double check you would use one of the points, for example (1,-1) you would do 1+2-4 to see if you would get -3 and do the same with -1, -1+2-4. I hoped this helped!

Answer:

The area could be 50x250 or 125x100

Step-by-step explanation:

L+2W = 350

LW = 12500

L = 350-2W

(350-2W)W = 12500

350W - 2W^2 = 12500

W = 50,125

L = 250,100

So, the area could be 50x250 or 125x100

Answer:

Step-by-step explanation:

The shorter sides of the porch can be found by subtracting 2.5m from 3m to get .5m; the longer sides are found by looking at the opposite end of the tent at the rectangle with a 1 inside of it. That 1 indicates the length of the rectangle, which is the same for the porch's length. That means that the perimeter is .5+1+.5+1 which is 3m total.

Answer:

[tex]z = (6,-1)[/tex]

Step-by-step explanation:

The missing parameters are:

[tex]x = (3,-1)[/tex]

[tex]y = (3,5)[/tex]

[tex]yz= \sqrt{45[/tex] --- Hypotenuse

Required

The coordinate of Z

First, calculate the distance xy

[tex]xy = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

[tex]xy = \sqrt{(3 - 3)^2 + (-1 - 5)^2}[/tex]

[tex]xy = \sqrt{0 + 36}[/tex]

[tex]xy = \sqrt{36}[/tex]

[tex]xy = 6[/tex]

By Pythagoras theorem, distance xz is:

[tex]yz^2 = xz^2 + xy^2[/tex]

[tex](\sqrt 45)^2 = xz^2 + 6^2[/tex]

[tex]45 = xz^2 + 36[/tex]

Collect like terms

[tex]xz^2 =45-36[/tex]

[tex]xz^2 =9[/tex]

[tex]xz = \sqrt{9}[/tex]

[tex]xz = 3[/tex]

This means that z is 3 units to the right of x

We have:

[tex]x = (3,-1)[/tex]

The rule to determine z is:

[tex](x,y) \to (x + 3, y)[/tex]

So, we have:

[tex]z = (3 + 3,-1)[/tex]

[tex]z = (6,-1)[/tex]
