Answer:

(2, 34 )

Step-by-step explanation:

Since the points vary inversely then half the x, means double the y, thus

(2, 34) or (1, 68 ) would also belong in this inverse variation

Answer:

769.46 miles

Step-by-step explanation:

Please have a look at the photo attached in this answer

The missing part of the angle is 32 degrees, so the total angle of B is:

32 + 73 = 105 degrees.

Let x is the distance from airport A to airport C to the nearest tenth of a mile, we use cosine law to find x:

$x^{2}$ = $570^{2} + 390^{2}$ - 2(570)(390)cos(105)

<=> $x^{2}$ = 592070

<=> x = $\sqrt{592070}$ = 769.46 miles

Mashutka [201]

Answer:

Option A. is the correct option.

Step-by-step explanation:

If a number is divisible by 5 it is not necessary that the number will be divisible by 10.

For example: 25 is the number divisible by 5 but not divisible by 10.

Or in other words a number divisible by 5 should be even to be divisible by 10.

So for the conditional statement : A number is divisible by 10 if and only if it is divisible by 5 will be false because any one out of these two statements is false. We know biconditional is true only when both the statements are true or false means both the statements should have same truth value.

Therefore Option A. is the correct option.

A closed box has a square base with side length l feet and height h feet. Given that the volume of the box is 29 cubic feet, exp

qwelly [4]

Answer:

The surface area of the box in terms of l is $2l^2 +116/l$

Step-by-step explanation:

The length of the box = $l$

The height of the box = $h$

The volume of the box can be obtained by multiplying the surface area of the base by the height of the box.

The surface area of the base of the box is a square, so it will be obtained by multiplying $l \times l = l^2$

hence volume = $l^2 \times h =29$

Notice that we are told to give our answer in terms of l, so we will make h the Subject of the formula in the above equation.

$h =29/l^2$

In the next phase, we are to find the surface area of the box.

The box has a square base, hence it will be made up of

2 squares with 4 rectangles. This is assuming the top is closed.

This means the surface area will be

$2(l^2) +4 (l\times h)$

recall $h = 29/l^2$

Hence, surface area =

$2(l^2) +4(l \times 29/l^2)\\2l^2 +116/l$

The surface area of the box in terms of l is $2l^2 +116/l$

Which will result in a difference of squares? (negative 7 x 4)(negative 7 x 4) (negative 7 x 4)(4 minus 7 x) (negative 7 x 4)(ne

earnstyle [38]

An expression is defined as a set of numbers, variables, and mathematical operations. The expression that will result in the difference in the squares is (7x+4)(7x-4).

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The difference between the squares can be written as,

$a^2-b^2=(a+b)(a-b)$

The expression that will result in the difference in the squares will be

$(7x+4)(7x-4)=(7x)^2-(4)^2$

Thus, the expression that will result in the difference in the squares is (7x+4)(7x-4).
