Find the value of x.l

Answer:

C) d=400t

Step-by-step explanation:

400mph means 400 miles per hour. (So every hour 400miles is covered due to the fact that its constant)

Therefore, to have the total distance, we take the 400 and multiply it by the amount of Time spent. (T in this inatance)

Answer:

44. (Sorry if im incorrect. I don't clearly understand the question)

Step-by-step explanation:

Answer:

14 or -12

Step-by-step explanation:

Start by writing an equation for this.

84 = x * (2x + 2)

This expression works because 84 is the product of the number (x) and twice the number plus 2.

Using the equation, solve for x.

84 = x * (2x + 2)

First, simplify.

84 = 2x^2 + 2x

Subtract 2x^2 + 2x to make the equation equal to 0.

84 - 2x^2 + 2x = 0

Factor:

−2(x − 6)(x + 7) = 0

Set factors equal to 0.

x − 6 = 0 or x + 7 = 0

x = 6 or x = -7

x represents the smaller number. The larger number is 2x + 2.

So double x and add 2.

2(6) = 12 and 12 + 2 = 14 so that's one of the options

2(-7) = -14 and -14 + 2 = -12 so that's the other.

Check:

14 * 6 = 84

-12 * -7 = 84

Answer:

x=7

Step-by-step explanation:

8(1X/4 +12 - 1 x 1/2X)=82

8(X/4 +12-1 x 1/2 x X)=82

8(X/4+ 12 - 1/2x)=82

8 X x/4 + 96+8 X -x/2=82

2x +96 +8 X -x/2=82

2x +96+ 8(-1)/2=82

2x +96 -8x/2 =82

2x+96-4x=82

-2x+96=82

-2x=-14

x=7

Answer:900 square units

Step-by-step explanation:

The radius is 90 units. Then the area of the shaded sector will be 900π square units.

Let r be the radius of the sector and θ be the angle subtended by the sector at the center. Then the area of the sector of the circle will be

A = (θ/360°) πr²

The circumference of circle T is 180π units. Then the radius of the circle is given as,

C = 180π

2πr = 180π

r = 90 units

Then the area of the sector is given as,

A = (40°/360°) π x 90²

A = 900π square units

The area of the shaded sector will be 900π square units.

More about the area of the sector link is given below.

Answer:

4(2g+4)

Step-by-step explanation:

8g+16

Since this expression represents the total perimeter, we need one side length. So we divide this by 4, because it's a square and all sides are of equal length.

8/4=2

16/4=4

One side is 2g+4. So multiply that equation by 4.

4(2g+4)

Answer:

height of the wall ] is 48.25ft

Step-by-step explanation:

Given data

Length of ladder= 50ft

Angle= 75°

We want to find the Height of the wall

Applying the SOH CAH TOA

sin ∅= opposite/hypotenus

sin 75= opposite/ 50

0.965= opposite/ 50

opposite=0.965*50

opposite=  48.25ft

Hence the height of the wall ] is 48.25ft

The graph for the inequality given is graph 1.

An inequality is a relation between two numbers or expressions that are not equal. It can show which of them is greater or smaller by using symbols like < or >. It can also be a statement of fact about the order relationship of quantities.

Given that an inequality, 2-(x+3) < 4 -2x, we need to determine its graph,

For the same solving the inequality,

2-(x+3) < 4 -2x

2-x-3 < 4 - 2x

Add x to both sides,

2-3 < 4-x

-1 < 4-x

Subtract 4

-1-4 > -x

x > 5

Since, the x is greater than 5 so the graph will be the numbers that greater than 5,

Hence, the graph is 1.

A rectangle is a 2-D shape with 4 angles. The length of the garden if it is 12 feet wide is 3 feet

A rectangle is a 2-D shape with 4 angles. The formula for calculating the perimeter of a rectangle is expressed as:

P = 2(length + width)

Given

Perimeter = 30 feet

width = 12 ft

Substitute

30 = 2(l + 12)

15 = l + 12

l = 3 feet

Hence the length of thegarden if it is 12 feet wide is 3 feet

Answer:

1 < x

Step-by-step explanation:

We have to used same order of operations just as we would in an equation;

15 > -x + 16

=> First subtract 16 from each side

-1 > -x

=> To bring x to positive, divide each side by -1 (Since we are dividing by a negative value, the inequality sign will switch)

Therefore the answer is: 1 < x
