Which equation has a graph that is a horizontal line?

a.
x – 7 = 0

b.
2y + 3 = 4

c.
x = y

d.
x + y = 0

Answer:

5.2

Step-by-step explanation:

distance(Mercury, Sun) = 5.8 x 10^7

distance(Venus, Sun) = 1.1 x 10^8

distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7

The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.

simply subtract 5.8 from 11.0.

This gives us a result of 5.2 x 10^7.

Answer:

75m^3

Step-by-step explanation:

[tex]\hookrightarrow \: volume = 1766250 {m}^{2} [/tex]

As we have,

[tex]\hookrightarrow \: volume = \frac{4}{3} \pi {r}^{3} [/tex]

Now,

[tex]\hookrightarrow \: 1766250 {m}^{3} = \frac{4}{3} \times 3.14 \times {r}^{ 3} \\ \hookrightarrow \: 5298750 {m}^{3} = 12.56 {r}^{3} \\ \hookrightarrow \frac{5298750 {m}^{3} }{12.56} = {r}^{3} \\ \hookrightarrow {r}^{3} = 421875 {m}^{3} \\ \hookrightarrow r = \sqrt[3]{421875 {m}^{3} } \\ \hookrightarrow 75 {m}^{3} [/tex]

Answer:

6 [tex]\frac{1}{12}[/tex] (6 1/12)

Question explanation:

First: 9 [tex]\frac{3}{4}[/tex] (9 3/4)

Convert any mixed number to fractions.

Then you initial equation becomes:

[tex]\frac{49}{4} - \frac{5}{2}[/tex]

(49/4 - 5/2)

Applying the fractions formula for subtraction,

(49 x 2) - (5 x 4)

4 x 2

98 - 20

8

= [tex]\frac{78}{8}[/tex]

(78/8)

Simplifying 78/8, the answer is:

9 [tex]\frac{3}{4}[/tex]

(9 3/4)

Second: 5 [tex]\frac{3}{4}[/tex] (5 3/4)

Convert any mixed numbers to fractions.

Reduce fractions where possible

Then your initial equation becomes:

39 - 4

4 - 1

Applying the fractions formula for subtraction.

(39 x 1) - (4 x 4)

4 x 1

39 - 16

4

= [tex]\frac{23}{4}[/tex] (23/4)

Simplifying 23/4, the answer is

5 [tex]\frac{3}{4}[/tex]

(5 3/4)

Answer:

[tex]6\frac{1}{12}[/tex] yards

Step-by-step explanation:

Marcella bought 12 1/4 yards of ribbon. She uses 2 1/2 yards of ribbon for gift packages and 3 2/3 yards to tie balloons.

The amount ribbon she had at the beginning: [tex]12\frac{1}{4}[/tex]

The amount she used: [tex]2\frac{1}{2} +3\frac{2}{3}\\[/tex]

Our expression: [tex]12\frac{1}{4} -(2\frac{1}{2} +3\frac{2}{3} )[/tex]

LCM of 2, 3, and 4: 12

2:

2, 4, 6, 8, 10, 12, 14, 16, 18, 20

3:

3, 6, 9, 12, 15, 18

4:

4, 8, 12, 16, 20

[tex]12\frac{1}{4} -(2\frac{1}{2} +3\frac{2}{3} )\\\\\frac{4*12+1}{4} -(\frac{2*2+1}{2} +\frac{3*3+2}{3})\\\\\frac{49}{4}-(\frac{5}{2}+\frac{11}{3})\\\\\frac{147}{12}-(\frac{30}{12}+\frac{44}{12})\\\\\frac{147}{12}-\frac{74}{12}\\\\\frac{73}{12}\\\\6\frac{1}{12}[/tex]

Therefore, Marcella will have [tex]6\frac{1}{12}[/tex] yards of ribbons left.

Step-by-step explanation:

(2x - 3) + 8x = 180 (linear pairs)

10x - 3 = 180

10x = 180 + 3

10x = 183

x = 183÷10

x = 18.3

1 = 2x - 3

2 × 18.3 - 3

= 33.6

2 = 8x

8 × 18.3

146.4

Angle 1 + Angle 2 = 180

33.6. + 146.4. = 180

Answer:

1/2 tablespoons

Step-by-step explanation:

Subtract 1/2 from 1, you get 1/2.

Answer:

There is more powder in a whole, one.

The least here is 1/2, because 3/4 is beyond halfway of 1 and 1/2 is exactly halfway.

So, we subtract the least from the greatest which is;

1 - 1/2 = 1/2

22ft^3

Step-by-step explanation:

I took off the small bit to the bottom right first, then found the volume of the larger part (19). Then I added the volume of the smaller part (3). This gave me the answer of 22ft^3.

The volume of planter is 27 cubic feet .Therefore, amount of soil is needed to fill the planter will be 27 cubic feet.

Volume of the cuboid is the total space occupied by the cuboid in the three  dimensional space. It is calculated as:

Volume of cuboid = length × breadth × height

According to the given question

Planter is made up of two cuboids.

Therefore,

Amount of soil needed to fill the planter= volume of the planter

so, volume of the planter=(3×2×3)+(3×1×3)=27 cubic feet.

Hence, 27 cubic feet soil is need to fill the planter.

Answer:

Coordinates involve two points. (x,y)

Too find a pair (coordinate), use the x and y lines on the graph and see where the point falls.

For example

Point A is number 1 on the y axis

number -4 on the x axis

So, you would write the coordinate out at

(-4,1)

The y axis values are the second point, so after you plot all of letters, use the y axis numbers and number them from least to greatest so you can find the mystery word.

Answer:

495 min

Step-by-step explanation:

Answer:

945 minutes

Step-by-step explanation:

The first step is to find 10% of 450:

[tex]\frac{10*450}{100*1}[/tex]

10 times 450 is 4500 and 100 times 1 is 100

Then 4500 divided by 100 and the answer is 45 minutes.

After that add that 10% of 450 ( 45 ) to 450 to find the minutes he reads in the next month and the answer is 495 minutes.

So because you want the time he read in the two months add 450 and 495 tp get:

450 + 495 = 945

So Oliver read for 945 in the 2 MONTHS.

Answer:

12in

Step-by-step explanation:

15in squared - 9in squared is 144in and the square root of 144 is 12

Answer:

12 in

Step-by-step explanation:

Pythagoras' Theorem:  a² + b² = c²

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

let x = unknown side

Given:

Substituting the given values into the equation:

⇒ x² + 9² = 15²

⇒ x² + 81 = 225

⇒ x² + 81 - 81 = 225 - 81

⇒ x² = 144

⇒ x = √(144)

⇒ x = ±12

As the length is positive, x = 12 only.

Therefore, the length of the unknown side is 12 in.
