Angle 1 is congruent to ∠5 as they are corresponding angles on a transversal .

Angle 4 is congruent to ∠5 as they are alternate interior angles .

Answer:

C

Step-by-step explanation:

We'll have to use trigonometry for this.

First, note that in right triangle ABC, if we look from the perspective of angle A, the opposite side is x, the adjacent side is y, and the hypotenuse is 18.

In order to find x, then, we must use sine, which is opposite/hypotenuse. So:

sin(A) = sin(60) = opposite/hypotenuse = x/18

sin(60) is equal to (√3)/2, so multiplying both sides by 18 gives:

[(√3)/2] * 18 = 9√3

Already, we can tell that the answer is likely C, but let's find y to make sure.

We will use cosine to find y because cos = adjacent/hypotenuse.

cos(A) = cos(60) = adjacent/hypotenuse = y/18

cos(60) = 0.5, so multiplying both sides by 18 gives:

0.5 * 18 = 9

So, y = 9.

Thus, C is our answer.

Answer:

C

Step-by-step explanation:

Using the cosine/ sine ratio in the right triangle and the exact values

cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] and sin30° = [tex]\frac{1}{2}[/tex] , then

cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{x}{18}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2x = 18[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

x = 9[tex]\sqrt{3}[/tex]

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

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{y}{18}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2y = 18 ( divide both sides by 2 )

y = 9

Thus

x = 9[tex]\sqrt{3}[/tex] and y = 9 → C

X = 5

Step-by-step explanation:

When the lines are parallel, the corresponding angles are equal in measure then:

m<2 = m<6

The first step in this situation is to find Angle TSU. Then find x, which is 7, which can be put into the equation shown for Angle WST.

Answer:

1. A

2. D

3. A

4. A

Step-by-step explanation:

Question 1:

Switch sides:

5(5 + 4v) > 105

Divide both sides by 5:

5(5 + 4v) / 5 > 105/5

Simplify:

5 + 4v > 21

Subtract 5 from both sides:

5 + 4v - 5 > 21 - 5

Simplify:

4v > 16

Divide both sides by 4:

4v/4 > 16/4

Simplify:

v>4

Question 2:

Expand:

5m - 3m - 6 < 24 - 3m

Add similar elements:

2m - 6 < 24 - 3m

Add 6 to both sides:

2m - 6 + 6 < 24 - 3m + 6

Simplify:

2m < -3m +30

Add 3m to both sides and simplify:

5m < 30

Divide both sides by 5:

5m/5 < 30/5

Simplify:

m<6

Question 3:

Expand:

18x + 12 ≤ -39 + x

Subtract 12 from both sides and simplify:

18x ≤ x - 51

Subtract x from both sides and simplify:

17x ≤ -51

Divide both sides by 17 and simplify:

x ≤ -3

Question 4:

Add similar elements:

-3m + 5m = 2m

Expand and simplify:

2m ≥ -12m

Add 12m to both sides and simplify:

14m ≥ 0

Divide both sides by 14 and simplify:

m ≥ 0

Liam had a container of oatmeal that contained 5 and one-half cups of oatmeal.

= 5 1/2 cups of oatmeal

Liam ate StartFraction 4 over 9 EndFraction cup of oatmeal every morning before school for a week.

= 4/9 cup of oatmeal for a week

Which is the best estimate of the number of cups of oatmeal that Liam had left in the container at the end of the five-day week?

5 1/2 - 5( 4/9)

11/2 - 20/9

= L.C.M of the denominators = 18

= 9 × 11 - 20 × 2/28

= 99 - 40/18

= 59/18

Answer: 3 + 1/6x

Step-by-step explanation:

From the question, we are informed to write an algebraic expression that represents the sum of 3 and one sixth of.

In mathematics, sum means addition. Therefore, the algebraic expression will be gotten by adding 3 to 1/6 of x. This will be:

= 3 + (1/6 × x)

= 3 + 1/6x

Answer:

The account balance will be $2,614.16 after 10 years ⇒ D

Step-by-step explanation:

The formula for compound interest, including principal sum is:

[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where

Let us use this rule to solve the question

∵ Ted invests $1,077 in a savings account with a fixed annual interest

   rat 9% compounded three times per year

∴ P = 1,077

∴ r = 9% = [tex]\frac{9}{100}[/tex] = 0.09

∴ n = 3 ⇒ three times per year

∵ The time is ten years

∴ t = 10

Substitute these values in the rule above to find A

∵ [tex]A=1077(1+\frac{0.09}{3})^{3(10)}[/tex]

→ Use your calculator to find the answer

∴ A = 2,614.161681

→ Round it to the nearest cent (2d.p.)

∴ A = $2,614.16

∴ The account balance will be $2,614.16 after 10 years.

Answer:

y=4

Step-by-step explanation:

look at the picture. :) hope this helps

Answer:

y = 4

Step-by-step explanation:

Lets begin by combining like terms, starting with y. We can take the -y on the right, and bring it to the left side, adding it with the 3y already there. We are now at.

4y - 4 = 12

We now can take the -4 from the left and bring it to the right as +4.

4y = 16

We can now divide 16 by 4, getting 4 as the final answer.

Answer:

The dressmaker bought 3 yard of cotter and 2 yards of silk

Step-by-step explanation:

So what you do it just put those equations into a graphing calculator and the point where they intersect is your answer

• Side of the square = 85/4 m.

• Area of the square

• perimeter of the square .

As we know that :

• Area of square = (side)²

=> Area of square = (85/4)²

=> Area of square = 7225/16

=> Area of square = 451.5 m².

Now ,

• Perimeter of square = 4 (side)

=> Perimeter of square = 4(85/4)

=> perimeter of square = 85 m.

HENCE, THE AREA IS 451.5M² AND PERIMETER IS 85M.

I hope it will help you.

Step-by-step explanation: If we look at the first conveyor belt, the rate is 12ft in 3 seconds, or 4 feet a second. The second conveyor belt moves at 21 feet in 7 seconds, or 3 feet a second. Since the two values are unequal, we can conclude it is not a proportional relationship.

Answer:

the answer is D

Step-by-step explanation:

The equation y = -16x² + 64x represents the given parabola that represents the height in feet of an object above the ground T seconds after it was launched from the ground.

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is a graph that shows the height in feet of an object above the ground {T} seconds after it was launched from the ground.

The given graph is a parabola. A quadratic equation represents a parabola.

The quadratic equation will have two roots at the point on which it cuts the {x} axis.

Consider the equation in option {C} as -

y = -16x² + 64x

For the point (4, 0), we can check the graph as -

0 = - 16 x 4 x 4 + 64 x 4

0 = 0

For the point (0, 0), we can check -

0 = 0 + 64 x 0

0 = 0

Therefore, the equation y = -16x² + 64x represents the given parabola that represents the height in feet of an object above the ground T seconds after it was launched from the ground.
