63 because our only evidence is 56 divided by 8 which is 7 so 7 x 9 equals 63

Angles T and V are complementary.Angle T has a measure of (2x+10) Angle V has a measure of 48 what is the value of x

never [62]

The answer is x=16

complimentary means that when the measures of both angles are added together they equal 90 degrees. To get the answer you subtract 48 from 90 and get 42. Then you subtract 10 from 42 because it is added in the parentheses. Then you divide 32 by 2 and you get your answer which is 16.

Is there a series of rigid transformations that could map ΔQRS to ΔABC? If so, which transformations could be used?

faltersainse [42]

Answer;

D Yes, ΔQRS can be translated so that Q is mapped to A and then reflected across the line containing QS.

Explanation;

-A rigid transformation is a transformation of a plane that preserves length. It is also called isometry. Reflections, translations, rotations, and combinations of these three transformations are examples of rigid transformations.

For the line segment whose endpoints are A (0, 0) and B (4, 3), find the x coordinate for the point located 2 over 3 the distanc

WARRIOR [948]

Answer:

<h3>3.3</h3>

Step-by-step explanation:

Distance between AB is expressed as;

AB = √(3-0)²+(4-0)²

AB = √3²+4²

AB =√9+16

AB = √25

AB = 5

2 over 3 the distance from A to B is expressed as;

2/3 of AB

= 2/3 * 5

=10/3

= 3.3

Find the value of x.<br><br> A.<br> 7<br> B.<br> 9<br> C.<br> 11<br> D.<br> 12

Arisa [49]

Use the law of cosines to solve for angle A. Plug your known side length values into the equation a^2 = b^2 + c^2 – 2bc cos A.

Then use the law of sines to find angle B. (Sin A/a = Sin B/b = Sin C/c).

Because the two red angles within B are congruent, divide your angle measure in half.

From there, do the law of sines to solve for x. Good luck!

I hopes this helps

Engineers must consider the breadths of male heads when designing helmets. The company researchers have determined that the popu

Answer:

The minimum head breadth that will fit the clientele is 4.4 inches.

The maximum head breadth that will fit the clientele is 7.8 inches.

Step-by-step explanation:

Let <em>X</em> = head breadths of men that is considered for the helmets.

The random variable <em>X</em> is normally distributed with mean, <em>μ</em> = 6.1 and standard deviation, <em>σ</em> = 1.

To compute the probability of a normal distribution we first need to convert the raw scores to <em>z</em>-scores using the formula:

$z=\frac{x-\mu}{\sigma}$

It is provided that the helmets will be designed to fit all men except those with head breadths that are in the smallest 4.3% or largest 4.3%.

Compute the minimum head breadth that will fit the clientele as follows:

P (X < x) = 0.043

⇒ P (Z < z) = 0.043

The value of <em>z</em> for this probability is:

<em>z</em> = -1.717

*Use a <em>z</em>-table.

Compute the value of <em>x</em> as follows:

$z=\frac{x-\mu}{\sigma}\\-1.717=\frac{x-6.1}{1}\\x=6.1-(1.717\times 1)\\x=4.383\\x\approx4.4$

Thus, the minimum head breadth that will fit the clientele is 4.4 inches.

Compute the maximum head breadth that will fit the clientele as follows:

P (X > x) = 0.043

⇒ P (Z > z) = 0.043

⇒ P (Z < z) = 1 - 0.043

⇒ P (Z < z) = 0.957

The value of <em>z</em> for this probability is:

<em>z</em> = 1.717

*Use a <em>z</em>-table.

Compute the value of <em>x</em> as follows:

$z=\frac{x-\mu}{\sigma}\\1.717=\frac{x-6.1}{1}\\x=6.1+(1.717\times 1)\\x=7.817\\x\approx7.8$

Thus, the maximum head breadth that will fit the clientele is 7.8 inches.
