Step-by-step explanation:

For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

Width=length

Let's assign a variable for the width, and call it x.

Since the width is equal to it's length, we can also call the length x.

The perimeter formula for a rectangle is 2(l+w).

Hope this helps!

Answer:

[tex]105ft[/tex]

Step-by-step explanation:

Since it's saying that the width of a rectangle is its length, that means all the sides of the rectangle are equal.

Since a rectangle has only 4 sides, we can divide the perimeter of the rectangle (420 ft) by 4 (sides)

Note: perimeter is the sum of all sides!

420 ÷ 4 = 105

Hope this helps!

Answer:

0.460

Step-by-step explanation:

We solve using z score formula

z = (x-μ)/σ, where

x is the raw score = 129 calls

μ is the population mean = 130 calls

σ is the population standard deviation = 10 calls

Hence:

Z score = x - μ/σ

=129 - 130/10

=-0.1

Probability value from Z-Table:

For x less than 129 calls = x < 129

P(x<129) = 0.46017

Approximately to the nearest thousandth = 0.460

Therefore, the probability that during a given hour of the day there will be less than 129 calls, to the nearest thousandths is 0.460

Answer: Rectangle

Rhombus

Parallelogram

Step-by-step explanation:

A rectangle has four sides and the opposite sides are equal.

A rhombus is simply a flat shape that has 4 equal straight sides and the sides have equal length.

A square has all the four sides equal.

A parallelogram is a quadrilateral that has two pairs of parallel sides. It should be noted that the opposite sides of the parallelogram have equal length.

A trapezoid doesn't have two sides with equal lengths. Therefore, the correct answer to the question will be:

• Rectangle

• Rhombus

• Parallelogram

Answer:

1.5x+12=26

Step-by-step explanation:

Andy currently runs a total of 12 miles per week. He plans to increase that number by 1.5 miles, so number of miles increased in x weeks will be 1.5x and total number of miles ran in x weeks will be 1.5x+12.

Since Andy wants to reach a total of 26 miles per week, so we will equate the total number of miles ran in x weeks with 26.

x = 50

Step-by-step explanation:

<c = <e so:

5y - 4 = 76

5y = 80

y = 16

<c = 76

All triangle interior angles add up to 180 so:

x + 8 + 46 + 76 = 180

x + 130 = 180

x = 50

Answer:

The choose (A)

A- (x+3)²+(t+5)²=16

Answer:

A (x + 3)^2 + ( y + 5 )^2 = 16

Step-by-step explanation:

The formula for equation of a circle is (x - h ) ^2 + ( y - k ) ^2 = r ^2

                                                            ( h , k ) represent the coordinates

                                                              r represents the radius

Plug in the numbers ( x - (-3) ) ^2 + ( y - (-5) ) ^2 = 4 ^2

2 negatives make a positive

So the equation would be (x + 3)^2 + ( y + 5 )^2 = 16

You also need to make sure you square the radius

Answer:

$120,000

Step-by-step explanation:

Provided that  

The price of the new car is $750,000

And, the saving percent is 16%

We need to calculate out the saving amount for the deposit

Therefore, the saving amount is

= $750,000 × 16%

= $120,000

Basically we multiply these two things to each other in order to get the saving amount

Answer:

Rewrite the equation as 28a^4+ma^3−19a^2−2a+3=(7a^2+2a−3)(4a^2−1).

28a^4+ma^3−19a^2−2a+3=(7a^2+2a−3)(4a^2−1)

Simplify (7a^2+2a−3)(4a^2−1).

28a^4+ma^3−19a^2−2a+3=28a^4−19a^2+8a^3−2a+3

Move all terms not containing m to the right side of the equation.

ma^3=8a^3

Divide each term by a3 and simplify.

m=8

Answer:

1.4

Step-by-step explanation:

33/23 = 1.434 ≈ 1.4 (rounded to the nearest tenth)

The answer is 1.43

An improper fraction is a fraction where the numerator is greater than or equal to the denominator.  For example, 3/2 is an improper fraction, but 2/3 is a proper fraction, whose denominator is greater than the numerator.

Given here: The fraction 33/23 which is roughly equivalent to 1.43

We know, To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, 6/10. If needed, simplify the fraction.  And To convert a fraction to a decimal, we'll just divide the numerator...by the denominator.

Thus 1.43=33/23

Hence, The answer is 1.43

Answer:

According to the graph, if only one unit was produced, the cost per unit would be $1.00. In reality, the company would not call in its worker and start up the equipment to produce one unit. What safeguard do you think that many manufacturers use to avoid this type of problem?

The per-unit cost will be as follows,

a) Wichita factory has cost function as more up to 25000 units and less for above 25000 units.

b) Piece wise function for cost per units for production of units can be written as

C(x) = cost per unit, will be as follows,

C(x)=1÷x,0 [tex]\leq[/tex] x [tex]\leq[/tex] 25000,

=0.8÷x, 25000 [tex]\leq[/tex] x [tex]\leq[/tex] 35000,

C) cost per unit for 35000 unit

=C(35000)= 0.8÷35000

Cost per unit  is referred to the cost of goods sold or the cost of sales, is how much money a company spends on producing one unit of the product they sell.

Thus, the cost per unit will be 2.28(10⁻⁵).

Answer:

Step-by-step explanation:

As Jaxon holding his hands a distance of 2.5 feet above the ground.

means h1= 2.5 feet

elevation angle from the hand is 33° so ∅=33°

distance of kite from his hand is  150 feet

so from the image we can see , now

as we know that  ,

Sin∅ =h2/150

Sin33°=h2/150

0.55 =h2/150                   (Sin33°= 0.545)

so h2= 81.70 feet

so height from ground is (H)=h1+h2= 2.5+81.70

H=84.20 feet
