5/8 + 3/4
_______
-2/3 - 5/6

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:

$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

Step-by-step explanation:

According to the volume formula, you multiply length x width x height

Answer:

D; 1*9*4

Step-by-step explanation:

Since the formula for the volume of a rectangular prisim is L*W*H (length times width times height), it would be 9*4*1. However, since the order doesn't matter (due to the commutative property of multiplication) it would be D.

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

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

Now that we’ve learned how to solve word problems involving the sum of consecutive integers, let’s narrow it down and this time, focus on word problems that only involve finding the sum of consecutive even integers.

But before we start delving into word problems, it’s important that we have a good understanding of what even integers, as well as consecutive even integers, are.

Even Integers

We know that even numbers are integers that can be divided exactly or evenly by 22. Thus, the general form of the even integer nn, is n = 2kn=2k, where kk is also an integer.

In other words, since even numbers are the multiples of 22, we can represent an even integer nn by 2k2k, where kk is also an integer. So if we have the even integers 1010 and 1616,

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.

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

[tex]B(x) = (1.3)^{4x + 1}[/tex]

Required

Ratio B(x) to A(x)

This is calculated as:

[tex]R(x) = B(x) : A(x)[/tex]

Express as fraction

[tex]R(x) = \frac{B(x) }{A(x)}[/tex]

Substitute: [tex]A(x) = (1.3)^{x + 9}[/tex] and  [tex]B(x) = (1.3)^{4x + 1}[/tex]

[tex]R(x) = \frac{(1.3)^{4x+1}}{(1.3)^{x+9}}[/tex]

Apply law of indices

[tex]R(x) = (1.3)^{4x-x+1-9}[/tex]

[tex]R(x) = (1.3)^{3x-8}[/tex]

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

= 2.28(10⁻⁵)

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:

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

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

Identify

a = 2/3

b = 3/4

c = 1/2

a(b - c²)

Step 2: Evaluate

Answer:

C. 1/3

Step-by-step explanation:

Replace each letter with their corresponding value and simplify using the order of operations:

a(b - c*c)

turns into:

[tex]\frac{2}{3} (\frac{3}{4}-(\frac{1}{2}*\frac{1}{2}))[/tex]

You want to remember that order of operations follows the rules of PEMDAS. The operations within the parentheses come first.

1/2 times 1/2 = 1/4

Now we have:

[tex]\frac{2}{3}(\frac{3}{4}-\frac{1}{4})[/tex]

Then 3/4 - 1/4 = 2/4 = 1/2

[tex]\frac{2}{3}(\frac{1}{2})[/tex] = 1/3

Therefore your answer is C. 1/3

Step-by-step explanation:

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

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:

E) 150°

Step-by-step explanation:

angle adjacent to 70° angle is 110°

the angle supplemental to 'x' must be 180-(40+110) or 30°

this means 'x' must be 150°
