a. 6ft
b. 3 ft
c. 36 ft
d. 12 ft

To solve you can use inverse operations.

Here are the steps to find the answer:

1. Write out the equation: -6(x-2)+3x= -3(x+3) +21

2. Distribute both sides: -6x+12+3x= -3x-9+21

3. Simplify both sides: -3x+12=-3x+12

4. This equation is true for all values, or infinity, because the equation is the same on both sides

Answer:

The sides are 3 and 9

Step-by-step explanation:

Since this is a right triangle, we can use the pythagorean theorem

a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse

x^2 + (3x)^2 = (3 sqrt(10))^2

x^2 + 9x^2 = 9*10

10x^2 = 90

Divide each side by 10

x^2 = 90/10

x^2 =9

Take the square root of each side

x = sqrt(9)

x = 3

The sides are x=3  and 3x = 3(3) = 9

Answer: x=10

Step-by-step explanation:

Since the original statements were x, 3x, and 3[tex]\sqrt{x}[/tex], is already given as 10 in 3[tex]\sqrt{x}[/tex], therefore, 3x is 3*10 and x is 10

The graph will start at the origin and slope up and to the right.

Using graph, the relationship between time x, and distance from home, y can be shown. The graph will start at the origin and go up to the right the best option is D.  

A graph is "diagrammatic or pictorial representations of collections of data in a organized manner".

According to the question,

The horizontal line or x-axis of the graph represents time taken during walk and the vertical line or y-axis of the graph represents distance traveled with respect to time.

Since walking start at home is taken as origin in the graph and reaching to school is noted in go up to the right of the graph.

Hence, using graph, the relationship between time x, and distance from home, y can be shown. The graph will start at the origin and go up to the right the best option is D.

In this question we are given the following values:

x = 2

y = -3

z = -1

Given the expression:

To evaluate, let's substitute for 2, -3 & - 1 for x, y & z respectively

Therefore,

[tex] x^2 z^2 -y^2(x+z) [/tex]

Substituting values, we have:

Option D; 5 to 1

We are told that the diagram is divided into equal parts.

Now, from the given, we can see that there are 6 equal parts. However, out of the 6 equal sections, only one section is shaded while 5 sections are unshaded.

This means that the ratio of unshaded sections to shaded sections is; 5 to 1.

In conclusion, the ratio of unshaded sections to shaded sections from the given diagram that was divided into equal parts is; 5 to 1.

Step-by-step explanation:

Either enter an exact answer in terms of pi or us 3.14 for pi and enter your answer as a decimal.

The arc length of a partial circle whose radius is 8 and measure of the central angle is 90 degrees is 12.

To find the arc length of a partial circle, we can use the formula:

Arc Length (L) = θ × r,

where L is the arc length, θ is the central angle in radians (or degrees), and r is the radius of the circle.

In this case, the radius (r) is given as 8 units, and the measure of the central angle (θ) is given as 90 degrees. However, we need to convert the central angle from degrees to radians before plugging it into the formula, as trigonometric functions work with radians.

To convert degrees to radians, we use the conversion factor: π radians = 180 degrees.

θ (in radians) = 90 degrees × (π radians / 180 degrees) ≈ 1.57 radians.

Now, we can calculate the arc length:

Arc Length (L) = 1.57 radians × 8 units ≈ 12.

if you spilt it into a 2x2x1 and a 1x2x1 you can count that there are 6 cube units

Answer:6 cubes

Step-by-step explanation:

There are 2 ways that I think you could solve this.

1. First, you could make those 2 missing cubes actual cubes, so then you could find the volume of the cube by doing 2x2x2(length x width x height) and you would get 8 cubes. After that, you would take away the two missing cubes, and you would get 6 cubes.

2. You could also just count the cubes. I counted the two inner cubes and then counted the 4 outer cubes, and got 6 cubes.

Answer:

[tex]\frac{\sqrt{8} }{\sqrt{10} }[/tex]

Step-by-step explanation:

A perfect square is a number that has two identical factors, meaning it can be square rooted. The numbers 64 and 100 are an example:

8 · 8 = 64

10 · 10 = 100

So when you take the square root of [tex]\frac{64}{100}[/tex], you get:

[tex]\frac{\sqrt{8} }{\sqrt{10} }[/tex]

It doesn't say to simplify, so we can just leave it at that.

Answer:

11.56

Step-by-step explanation:

Equation To write :2 {x+ ( x+5) }=30

Let's solve your equation step-by-step.

2(x+x+5)=30

Step 1: Simplify both sides of the equation.

2(x+x+5)=30

(2)(x)+(2)(x)+(2)(5)=30(Distribute)

2x+2x+10=30

(2x+2x)+(10)=30(Combine Like Terms)

4x+10=30

4x+10=30

Step 2: Subtract 10 from both sides.

4x+10−10=30−10

4x=20

Step 3: Divide both sides by 4.

Answer:

Step-by-step explanation:

Okay, so P = perimeter, and the problem says P = 30

 Let's call x the width, and y is the length.

In the perimeter formula, 2X + 2Y = P

so 2X + 2Y = 30

The problem also tells us that that x = y+5, so now let's do some substituting and replace X with Y+5

 2(y+5) + 2Y = 30

2y+10 +2Y = 30

4y+10=30

-10. -10

4y=20

Y=5

Answer:

2.1 cups per day and you will run out of juice in 5 days.

Step-by-step explanation:

1.2 cups + .9 cups = 2.1 cups per day

10.5 divided by 2.1 = 5 days

From the equation calculated, 2.1 cups of juice will be drank daily.

The total juice that will be drank each day will be:

= 1.2 + 0.9 = 2.1

Therefore, 2.1 cups of juice will be drank daily.

The number of days before the person runs out of drink will be:

= 10.5 / 2.1

= 5

Step-by-step explanation:

The surface area of a rectangular pyramid is formed by one rectangle at the center, and four triangles attached to it.

In this case, the rectangle has dimensions of 10 inches (height) by 4 inches (length). 2 triangles have a base of 10 inches and a height of 5 inches. The other 2 triangles have a an area of 13.6 square inches.

Basically, we need to find the area of the other two triangles and the area of the rectangle at the center.

[tex]A_{1}=4 \times 10 = 40 \ in^{2}[/tex]

[tex]A_{2}= 2(\frac{1}{2} \times 10 \times 5 )=2(25) \ in^{2} = 50 \ in^{2}[/tex]

Now, we sum all areas

[tex]A=40 + 50 + 13.6 +13.6= 117.2 \ in^{2}[/tex]

Therefore, the total surface area is 117.2 square inches.
