Answer:

C Between 4 and 5, but closer to 4

Step-by-step explanation:

cube root of 70 is 4.1212

Answer: 5.5 inches

Step-by-step explanation:

       Using the formula for the area of a square, we can plug the known values in and solve.

a = x²

30 = x²

[tex]\sqrt{30 } =\sqrt{x^2}[/tex]

[tex]\sqrt{30 }[/tex] = x

5.477 ≈ x

       Now, we will round to the nearest tenth.

5.477 ≈ 5.5 inches

y = -3/2x - 20.5 is the line crossing through (-7,10) perpendicular to 2x - 3y= -3

In an equation, parallel lines have the opposite reciprocal slope. In other words, if a line's slope is a positive fraction, its reciprocal slope is negative.

Here given that  2x - 3y= -3

can also be written as

y = 2/3x + 1

Here 2/3 is the slope and 1 is the y-intercept

To find a parallel line to the following equation, use the opposite reciprocal slope and point, then solve using the point-slope formula.

y - y₁ = m(x - x₁)

We have, m = -3/2,  x₁ = -7 and y₁ = 10

y - 10 = -3/2(x - (-7))

y - 10 = -3/2(x + 7)

y - 10 = -3/2x - 21/2

y = -3/2x - 21/2 + 10

y = -3/2x - 20.5

The age of Walter at the end of year 1999 will be equal to 55 years.

What is algebra ?

Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.

Let's assume respective age of Walter and Walter's grandmother is x and y years respectively.

In 1994 , age of Walter was  :

x = y / 2

or y = 2x

It is also given that the sum of years they were born is 3838.

The year Walter was born = (1994 - x)

The year Walter's grandmother was born :

= (1994 - y)

= 1994 - 2x                                  (∵ y = 2x)

So , we can write an equation to find out Walter's age which is :

1994 - x + 1994 - 2x = 3838

3988 - 3x = 3838

3x = 3988 - 3838

x = 150 / 3

x = 50 years

or the age of Walter in 1994 is 50 years.

At end of 1999 Walter's age will be:

= 50 + 5.

= 55 years

Therefore , the age of Walter at the end of year 1999 will be equal to 55 years.

The type of transformation that preserves the symmetry is Vertical translation.

For instance, a parabola is still symmetric about the y-axis if you move it up. It loses its symmetry if you move it to the left or right. Reflection keeps both even and odd functions symmetrical.

The symmetry of a function is described using the terms even and odd. On a graph, an even function is symmetric about the y-axis. An odd function has symmetric behavior around a graph's origin [tex](0, 0)[/tex]. This means that if you rotate an odd function 180 degrees around the origin, the function you started with will still exist.

It can be determined that a relation represented as an equation is a function if and only if for each value on x-axis, there is a corresponding value on Y-axis.

which also signifies that for each value of x , there is a value of y which exists and is real.

A function is a mapping from one set to another such that nothing in the first set is mapped to more than one thing in the second set.

Or in simple words if there is no corresponding value of y for any x, then that is not a function.

For example,

[tex]x^{2} +y^{2}[/tex]=1

when the value of x is 0 , then value of y is 1 or -1, Thus, it will not be a function.

Answer:

$675.75

Step-by-step explanation:

To find the sale price of the recliner, we can multiply 15% by the regular price.

15% = 0.15

(0.15)(795.00) = $119.25

This gives us the amount that the sale takes off from the regular price. We can subtract that from the regular price to find the sale price.

795.00 - 119.25 = $675.75

A bonus shortcut way to get our answer would be to subtract 15% from 100%.

100% = 1.00

1.00 - 0.15 = 0.85

This tells us that the sale price is 85% of the regular price. Using this information, we can multiply 85% by the regular price to also get our sale price.

85% = 0.85

(0.85)(795.00) = $675.75

An equation that represents the cost of one pound of bananas in terms of the cost of one pound of apples is,

⇒ b = 2a + 30

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Cost of one pound of grapes = g

Cost of one pound of apples = a

Cost of one pound of banana = b

Since, The cost of one pound of grapes is 15 cents more than one pound of apples.

It can be written as;

g = a + 15   .... (i)

And, The cost of one pound of bananas is twice as much as one pound of grapes.

It can be written as;

b = 2g  ..... (ii)

To find an equation that represents the cost of one pound of bananas in terms of the cost of one pound of apples as,

Put the value of g from (i) in (ii) we get,

b = 2 ( a + 15 )

b = 2a + 30

Hence, An equation that represents the cost of one pound of bananas in terms of the cost of one pound of apples is,

The measure of the supplementary angles are 48° and 132°.

Let the measure angle be x.

Its supplementary angle will be x + 84

We know that the sum of supplementary angles is 180°.

So, we get the equation as:

x + x + 84 = 180

Combining the like terms, we get that:

2 x + 84 = 180

Subtract 84 from both sides, we get that:

2 x = 180 - 84

2 x = 96

Divide both sides by 2, we get that:

x = 96 / 2

x = 48°

x + 84 = 48+ 84 = 132°

Therefore, we get that, the measure of the supplementary angles are 48° and 132°.

The number of minutes after liftoff of the plane at an altitude of 21,000 feet is 6 minutes

A function can be defined as an expression or law that shows the relationship between a dependent and independent variable.

Given the function;

a= 3400 t + 600

Where;

If the altitude is 21000 feet, let's determine the time

Substitute the value into the function

21000 = 3400t + 600

Step-by-step explanation:

The surface area of the prism is 200 cm².

The surface area of the prism is given by the formula:

Surface area (S) = 2 B + p h

where B is the area of base of prism

p = perimeter of base

h = height of the prism.

Perimeter = 2(5 + 3) cm

p = 16 cm

B = 5 cm × 4 cm = 20 cm²

h = 10 cm

Substituting it in the formula, we get that:

S = 2 B + p h

S = 2 (20) + (16) (10)

S = 40 + 160

S = 200 cm²
