The area of a rectangle is 25/42 and its width is 5/6. What is the length? ASAP

Answer:

5

Step-by-step explanation:

This is because |-5| is equal to 5

Answer:

It is 5

Step-by-step explanation:

The absolute value sign means how many spots that number is away from the 0 on the number line so it makes all numbers positive except if there is a negative sign on the outside of the absolute value sign

Answer:c

Step-by-step explanation:

Statement C is the most precise and correct to define an angle.

An angle is made when two rays, called as the arms of the angle meet at a common point, the common point is called the vertex of the angle.

The exact definition is what can explain in brief, the exact detail of the topic defined.

The definition that the space between two intersecting lines is simple to understand but is not completely explaining the technicality.

The angle is explained to the point in the Option C.

Answer: 36cm

Step-by-step explanation:

An isosceles triangle has 2 sides equal and one different from the other 2. Let's take the segment A C which measures 24cm as the base of our triangle, that means we'll have two equal unknown segments A B and B C. The perimeter of a shape is in simpler terms the distance right round it, therefore, if we add the length of all the three sides of the triangle we should get 96cm.

A C + A B + B C = 96cm

A B = B C

A C = 24cm

96cm - 24cm = 72cm

A B + B C = 72cm

72cm ÷ 2 = 36cm

The length of AB is 36 cm.

An Isosceles triangle ABC has two equal sides.

Let us consider  that equal sides AB and CB are x.

Given that,  AC = 24cm

Perimeter = AB + CB + AC

          [tex]x+x+24=96\\\\2x=96-24=72\\\\x=72/2=36cm[/tex]

Therefore, the length of AB is 36 cm.

Answer:

D. because all irrational numbers are real numbers.

Step-by-step explanation:

Real numbers include virtually all numbers we can come up with, either negative or positive, rational or irrational, decimals, etc. They are not imaginary numbers.

Irrational numbers include all numbers that cannot be written as a quotient of two integers. They are numbers whose decimals are never terminating. Examples include π, √2 etc.

Irrational are a subset of real numbers.

Therefore, the correct venn diagram that shows this relationship between Set R {real numbers} and Set Q {irrational numbers} is the venn diagram in option D (last option), because, all irrational numbers are real numbers.

Answer:

4, 15

Step-by-step explanation:

First of all, simplify the first equation. When you simplify, you get -2x-8 = -16, which you then add 8 to both sides. You get -2x = -8, so you divide both sides by -2 to get 4. In the second equation, you subtract 5 from both sides to get x/3= 5. Multiply both sides by 3 to get the value of x, and you'll get the equation of x=15, which is the answer.

3 x 80(4) = 960

80 multiply with 4 as the length of the sisi of the square is 80m and has four sisi.

Answer:

$99

Step-by-step explanation:

Cost of electricity per year= $165

Tax per month= 5%

Amount of tax paid per month= 5% of $165

= 0.05 × 165

= $8.25

Ella's family pays $8.25 tax per month

There are 12 months in 1 year

Ella's family will pay Ina year = $8.25 × 12

= $99

Ella's family will pay $99 tax for an entire year

Answer: A; 6.3%

Step-by-step explanation:

Problem 1

For the first problem, we first want to find y so that we can plug it into the expression.

We can use elimination method for the system of equations to solve.

3x+3y=21

3x-y=5

We subtract both equations to eliminate x.

4y=16                                        [divide both sides by 4]

y=4

Now that we know y, we can plug it into the expression.

[tex]\frac{4}{2} -3[/tex]                                         [divide]

[tex]2-3[/tex]                                         [subtract]

[tex]-1[/tex]

We know that the answer is A.

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

Problem 2

For the second problem, we need to know how to calculate percent error. The formula for precent error is [tex]\frac{|measured-exact|}{exact} *100%[/tex]. We know that the exact value is 80 because the buyer was supposed to given 80. 75 is the measured value because that was what the buyer was given.

[tex]\frac{|75-80|}{80} *100%[/tex]                               [subtract]

[tex]\frac{|-5|}{80} *100%[/tex]                                   [solve absolue value]

[tex]\frac{5}{80} *100%[/tex]                                     [divide]

[tex]0.0625*100%[/tex]                               [multiply]

[tex]6.25[/tex]

Since the problem said to round to one decimal place, we know that the answer is 6.3%.

Answer:

"if it is not an animal, then it is not a horse"

Step-by-step explanation:

Lets say we had an original statement that is "if a, then b." The contrapositive to this statement would be "if not b, then not a."

To find the contrapositive to a statement, you would swap and negate the hypothesis, or the "a" in the example statements above, and the conclusion, or the "b" in the example statements above.

For the statement "if it is a horse, then it is an animal", to find the contrapositive, lets first swap the hypothesis and conclusion:

"if it is an animal, then it is a horse"

Now lets negate both the hypothesis and conclusion. To do this, lets change the "it is" to "it is not" in both the hypothesis and conclusion.

"if it is not an animal, then it is not a horse"

And now we have the contrapositive to the statement.

Step-by-step explanation:

The perimeter of a rectangle is [tex]2l+2w[/tex], where l and w are the length and width respectively. Since we know the value of the length and width, we can substitute inside the equation.

[tex]2(x+5y) + 2(8x^2 - x + 4y)\\\\2x + 10y + 16x^2 - 2x + 8y[/tex]

We can now combine like terms to get [tex]16x^2 + 18y[/tex].

Answer:

Area= 4,200 square feet

Step-by-step explanation:

If I read your question correctly, I'm assuming the dots (".") mean a multiplication sign ("x").

If they are all being multiplied, use PEMDAS to solve this. First, find to value for any exponents you have (in this case, it's [tex]2^3[/tex] and [tex]5^2[/tex]).

[tex]2^3=2*2*2=8\\5^2=5*5=25[/tex]

Now that you have the values for these two exponents, multiply all the numbers together.

8 x 3 x 25 x 7 = 4,200

Answer:

2 equivalent ratios set equal to each other are a proportion

Step-by-step explanation:

A proportion is a statement of equality of two ratios. When you set two ratios equal to each other, you have a proportion. Two equivalent ratios are equal, so when you set two equivalent ratios equal to each other, you have a proportion.

Answer: 2 equivalent ratios set equal to each other are a proportion

The answers are 4,8, and 12.

Answer: 4 is 12 and 5 is 18

Step-by-step explanation: The midpoint of a line is the exact middle of the line. In other words, it splits the line into two equal parts.

From a formulaic standpoint, this looks like

AC = CB

And if we plug in the values it looks like this

AC = 12, so 12 = CB.

For the next problem,

AC + CB = AB

AC = 9, and since AC = CB, CB = 9 also.

So, once again just put the numbers in for the letters and you get

9 + 9 = 18
