Answer:

162.5

Step-by-step explanation:

You can set up a proportion

[tex]\frac{vw}{st}[/tex] = [tex]\frac{tr}{wu}[/tex]  plug in the numbers that you know and solve for vw

[tex]\frac{vw}{65}[/tex] = [tex]\frac{40}{16}[/tex]

I would simply [tex]\frac{40}{16}[/tex]  by dividing the numerator (top) and the denominator (bottom) by 8 to get [tex]\frac{5}{2}[/tex] which would be easier to work with

[tex]\frac{vw}{65}[/tex] = [tex]\frac{5}{2}[/tex]  Cross multiply

2vw = 5(65)

2vw = 325  Divide both sides by 2

vw = 162.5

The value of a is 30.1

The denominators of fractions must match in order to divide them. The numerators' quotient will be the quotient.

The phrase provided is,

a/12 = 30.1/12

We can directly cut the values if the denominator is the same. Since there is a 12 in the denominator on both the right and left sides in this case, remove 12 from both sides.

Thus, a = 30.1

Likewise, you can act in such manner,

a = (30.1 * 12) / 12

a = 30.1

Here, we take the right side of the left side denominator 12 and cancel 12.

Hence, A has a value of 30.1

Answer: 72 degrees

Step-by-step explanation: We know that angle DHG and angle EHF are congruent due to the vertical angles theorem. Since these two angle measures are congruent, this also means that the expression 6(x-2) is congruent to 3x+30. To find the angle measure of DHG, we need to find x. We can set these two expressions equal to each other and solve for x.

6(x-2) = 3x+30

6x-12 = 3x + 30

-3x -3x

3x-12=30

+12 +12

3x=42

~divide by 3 on both sides~

x = 14

Now that we know our x variable, we can substitute 14 into the expression for angle DHG.

6(14-2)

6(12)

72.

Answer:

∠DHG = 72°

Step-by-step explanation:

As ∠DHG and ∠EHF are vertical angles, they are congruent.

What are vertical angles?

Vertical angles are formed when two lines intersect, creating opposite angles. Those opposites are congruent (equal).

Equation:

∠DHG = ∠EHF

[6(x - 2)] = (3x + 30)

Step 1: Distribute 6 through the parentheses.

[tex]\implies 6(x) + 6(-2) = 3x + 30[/tex]

[tex]\implies 6x - 12 = 3x + 30[/tex]

Step 2: Subtract 3x from both sides.

[tex]\implies 6x - 3x - 12 = 30[/tex]

[tex]\implies 3x - 12 = 30[/tex]

Step 3: Add 12 to both sides.

[tex]\implies 3x - 12 + 12 = 30 + 12[/tex]

[tex]\implies 3x = 42[/tex]

Step 4: Divide both sides by 3.

[tex]\implies \dfrac{3x}{3} = \dfrac{42}{3}[/tex]

[tex]\implies \boxed{x = 14}[/tex]

Step 5: Substitute the value of x into ∠DHG to find its measure.

[tex]\implies \angle DHG = 6(14 - 2)[/tex]

[tex]\implies \angle DHG = 6(12)[/tex]

[tex]\implies \angle DHG = \boxed{72^\circ}[/tex]

Therefore, the measure of ∠DHG is 72°.

Given that,

It is divided into two sections, a 57-inch pipe. The length of one component is double that of the other.

We have to calculate the shorter piece's length.

Let us take the length of shortest piece as x

The principal with the given simple interest, rate of interest and time period is $4550.

Given that, interest = $637, rate of interest = 7% and time period = 2 years.

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.

We know that, simple interest = (P×R×T)/100

Put simple interest = $637, R=7% and T=2 years, we get

637 = (P × 7 × 2)/100

⇒ 14P=63700

⇒ P=63700/14

⇒ P= $4550

Therefore, the principal with the given simple interest, rate of interest and time period is $4550.

Answer:

(A) correct
(B) correct
(C) correct

Step-by-step explanation:

(A) is correct
Total survived = 713

Out of the 713 passengers who survived, the number of crew members = 215, the highest. The ratio of 215/713 is higher than any other ratio. This means 30% of those who survived were crew members. The next higher group of survivors was First Class passengers with a survival rate of 202/713 ≈ 28%

(B) is correct

There were 913 crew members. Out of this, 698 died 215 survived.
So it is more likely that given a person was a crew member, the person died than survived. That comprises 698/913 or 76% of crew members who died with only 24% survival rate

(C) is correct

There were 1516 passengers who died

Out of these, 528 + 698 = 1,226 were either third class or crew members and comprised 1226/1516 or approximately 81 percent of people who died

We need to know reflection of point about axes to solve the problem. The image of B (4,0) after reflection about y-axis is (-4,0).

Reflection about an axis means finding the point on the graph that is at an equal distance from the axis on the opposite side of the reflecting surface. The reflection can be about an axis or a line or origin. When a point is reflected about the x-axis, the sign of the y-coordinate of the point changes, when a point is reflected about y-axis the sign of the x-coordinate of the point changes and when a point reflects about the origin, the sign of both the coordinates change. Here in the question we need to find the reflection of point B (4,0) about y-axis, the image of point B will be (-4,0).

Therefore the image of point B(4,0) when reflected about y-axis is (-4,0).

a. The slope of the line for baby Claire growth is 0.8.

b. Baby girl Claire growth rate is faster than baby girl Grace growth rate.

Let's solve for the growth chart of baby grace.

Therefore,

a.

The rate of change in length of baby Grace can be found as follows:

rate of change = y₂ - y₁ / x₂ - x₁

Hence, using (4, 20)(6, 21.5)

rate of change = 21.5 - 20 / 6 - 4

rate of change = 1.5 / 2

rate of change = 0.75

b . The linear equation in point slope form can be found as follows;

y - y₁ = m (x - x₁)

where

Therefore,

y - 20 = 0.75(x - 4)

Let's tackle the growth chart for baby Claire,

a.

slope of the line = y₂ - y₁ / x₂ - x₁

Using (4, 22)(14, 30)

slope of the line = 30 - 22 / 14 - 4

slope of the line = 8 / 10

slope of the line = 4 / 5 = 0.8

b.

Therefore, Baby Claire growth rate is faster than baby Grace.

This is because bay Claire growth rate is 0.8 and baby Grace is 0.75.

A deck has a total of 52 cards.

The probability of getting a black 4 is then:

There are two lines a and b, Which are parallel lines and a line that cut the parallel lines a and b is transversal t.

1. Angle 8 is 86°

2. Angle 9 is 94° and

3. Angle 10 is 86°.

Given that,

There are two lines a and b, Which are parallel lines and a line that cut the parallel lines a and b is transversal t.

The interior angles are 7,8,9 and 10.

The angle 7 and 8 are consecutive angles and angle 7= 94°.

The angle 8 and 10 are alternative angles.

We have to find the angles 8,9 and 10.

We take,

The angle 7 and 8 are consecutive angles and angle 7= 94°.

Consecutive angles condition is Sum of the pair of consecutive angles is equal to 180°.

Now,

∠7+∠8=180°

94°+∠8=180°

∠8=180°-94°

∠8=86°

We got angle 8 as 86°.

Now, we take

The angle 8 and 10 are alternative angles.

Alternative angles condition is The pair of alternative angles are always equal if the two lines are parallel lines.

Now,

∠8=∠10

86°=∠10

∠10=86°

We got angle 10 as 86°.

Then we can say that the angle 7 and 9 are alternative angles.

Then,

∠7=∠9

94°=∠9

∠9=94°

We got angle 9 as 94°.

Therefore, The angle 7 is 94°, ∠8 is 86°, ∠9 is 94° and ∠10 is 86°.

step by step:

Start by setting it up with the divisor 33 on the left side and the dividend 94 on the right side.

The divisor 33 goes into the first digit of the dividend 9, 0 time(s). Therefore, put 0 on top.

Multiply the divisor by the result in the previous step (33 x 0 = 0) and write that answer below the dividend.

Subtract the result in the previous step from the first digit of the dividend (9 - 0 = 9) and write the answer below.

Move down the 2nd digit of the dividend 4

The divisor 33 goes into the bottom number 94, 2 time(s). Therefore, put 2 on top.

Multiply the divisor by the result in the previous step (33 x 2 = 66) and write that answer at the bottom.

Subtract the result in the previous step from the number written above it. (94 - 66 = 28) and write the answer at the bottom.
