Thinking in terms of 20% of 100 being 20, this question is very similar, just take of the extra 0 on the end of 100, 20% of 10 would be 2 (the extra 0 gets taken off on the answer too).

Therefore , the solution of the given problem of ratio comes out to be side lengths for each dimension would be 16 feet broad and 40 feet long.

A collection of integers "a" but instead "b" that seem to be equal can be found using the straightforward algorithm "a / b," at which "b" may be larger than zero. A ratio is created by combining two variable ratios. The ratio would just be 1:1 if there were just one male and three women. There are 1/4 men and 3/4 ladies in the group. Parts might be a separation between objects, a number, or a specific volumetric proportion of a component.

Here,

Call this element "x" for short.

As a result, the new breadth will be 8x and the new length, 20x.

We want a rectangle with the same aspect ratio to be formed by these new measurements.

We can make up the following equation in order to determine the value of "x" that preserves this aspect ratio:

=> (width of new rectangle / length of new rectangle) =

=> (length of original rectangle / width of new rectangle (width of original rectangle)

=> (20x) / (8x) = 20 / 8

When we simplify this solution, we obtain:

=> 2.5 = 2.5

Given that this equation holds for any value of "x," we can select any value of "x" and still retain the same aspect ratio.

So a rectangle with the same ratio of side lengths for each dimension would be 16 feet broad and 40 feet long.

The BR is the perpendicular bisector of AC by CPCTC (corresponding parts of congruent triangles are congruent).

Based on the given information that angles ABR and ACR are right angles, and AB = AC, we can conclude that triangles ABR and ACR are right triangles.

Using the shared hypotenuse AR and the reflexive property, we can determine that side AB is congruent to side AC.

With this information, the transitive property allows us to conclude that angle BAR is congruent to angle CAR. Next, using the HL congruence postulate, we can prove that triangle ABR is congruent to triangle ACR.

This means that side BR is congruent to side CR, and angle BAC is bisected by line segment BR by the definition of bisector.

Answer:

7606.62

Step-by-step explanation:

Start by finding how much you will have through the annuity. The question isn't that clear, so i will just assume it's an annuity due.

\(p(\frac{(1+i)^n-1}{i})*(1+i)\\i=.035/12= .0029166667\\n=10*12=120\\p=75 (given)\\75\frac{(1+.0029166667)^{120}-1}{.0029166667}*(1+.0029166667)= 10788.814149\\\)

Now just equate this to a time 0 payment at the same rate

\(10788.814149=(1+.0029166667)^{120}*x\\x= 7606.6228603=7606.62\)

As a quick note, if you were supposed to assume that your annuity was an annuity immediate the answer would be 7584.50.

Answer:

y = 2x^2

Step-by-step explanation:

Solve t first, and then you would have to solve r.

x = t^1/2

y = 2t

The rectangular equation represents the parametric equation y=2x².

The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.

According to the task content;

It follows that the parametric equations given are; x =t^(1/2) and y = 2t.

Since x =t^(1/2), then it follows that; x² = t.

Therefore, by substituting x² for t in y= 2t, then we have; y = 2x².

We are asked to find the arc CE in the given figure.

First, we need to find arc mBC then we can easily find arc CE

As you can see from the figure, ∠BAC is formed by two secants intersecting outside of circle.

The intercepted arcs are mDE (major arc) and mBC (minor arc)

So, we can use the property of "angle Formed by Two Secants" given by

Where

∠BAC = 20°

mDE = 100°

Let us solve the above equation for mBC

Now we can find the arc CE

Therefore, the arc CE is 100°

Step-by-step explanation:

you would do 42 divided by 7 which is 6 then subtract 2 from 7 and you would get 5

The expression that is always equivalent to sin x when 0° < x < 90° is (1) cos (90° - x). Option 1

To understand why, let's analyze the trigonometric functions involved. In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse. Since we are considering angles between 0° and 90°, we can guarantee that the side opposite the angle will always be the shortest side of the triangle, and the hypotenuse will be the longest side.

Now let's examine the expression cos (90° - x). The cosine of an angle is defined as the ratio of the length of the side adjacent to the angle to the length of the hypotenuse. In a right triangle, when we subtract an angle x from 90°, we are left with the complementary angle to x. This means that the remaining angle in the triangle is 90° - x.

Since the side adjacent to the angle 90° - x is the same as the side opposite the angle x, and the hypotenuse is the same, the ratio of the adjacent side to the hypotenuse remains the same. Therefore, cos (90° - x) is equivalent to sin x for angles between 0° and 90°.

On the other hand, options (2) cos (45° - x) and (3) cos (2x) do not always yield the same value as sin x for all angles between 0° and 90°. The expression cos x (option 4) is equivalent to sin (90° - x), not sin x.

Option 1 is correct.

Step-by-step explanation:

The critical value, given the sample size of 5 and the confidence level of 99. 0 percent would be 16. 812.

The critical values for the chi-squared (χ^2) distribution depend on the degree of freedom and the level of significance.

The degree of freedom for a chi-squared distribution typically equals the sample size minus 1 so the degrees of freedom here is:

= 5 - 1

= 4

The level of significance would be:

= 1 - 99. 0 %

= 0. 01

The critical value of the sample would therefore be found on a chi -squared distribution table for df = 4 and α = 0.01 to be 16. 812.

The value of missing x = 5

The value of missing y = 17 / 3

The standard line equation, y = mx + b, or the slope formula, m = (y2 - y1)/(x2 - x1), can both be used to find the slope, m.

According to the given information

Let two points be \((x_{1} , y_{1} )\) and \((x_{2} , y_{2} )\) are ( 3 , 8 ) and ( 6 , 15 )

Slope of the two points = \(\frac{y_{2}- y_{1} }{x_{2} -x_{1} }\)

                                       = \(\frac{15-8}{6-3}\)

                                       = 7 / 3

Let the equation passing through points  ( 3 , 8 ) be

\(( y - y_{1}) = m(x - x_{1})\)

y - 8 = 7/3( x - 3 )

3y - 24 = 7x - 21

3y = 7x - 21 + 24

3y = 7x + 3

When x = 2

3y = 14 + 3

y = 17 / 3

When y = 38/5

114/3 = 7x + 3

7x = 114/3 - 3

21x = 114 - 9

x = 5

So

The value of missing x = 5

The value of missing y = 17 / 3

The inequality that would represent the possible values for the number of hours washing cars, w, and the number of hours landscaping, is  

w + l ≥ 17.

What is inequality?

In mathematics, inequalities describe the relationship between two values that are not equal. Equal means to be equal, not. The "not equal symbol (≠)" is typically used to indicate that two values are not equal. But different inequalities are used to compare the values to determine whether they are less than or greater than.

Given:

Mackenzie is working two summer jobs, washing cars and landscaping. She must work at least 17 hours altogether between both jobs in a given week.

Total number of hours is w + l and it should be at least 17 hours, (equal to 17 or greater).

We can set inequality as:

w + l ≥ 17

Hence, the inequality that would represent the possible values for the number of hours washing cars, w, and the number of hours landscaping, is  w + l ≥ 17.
