Answer:

$4\frac{1}{2}$

Step-by-step explanation:

This question is basically saying: what is half of 7, or what is 7 divided by 2?

Based on this, it can be written both of the ways as:

»» $\frac{1}{2}$ of 7 <u>OR</u> 7 ÷ 2

So, just solve using either one and you’ll get 4.5 or $4\frac{1}{2}$ . But since the question wants the answer to be a mixed number, then choose $4\frac{1}{2}$ .

Hope this helps! :)

Solve for m y=mx+b ?

galben [10]

I’m not sure if you meant to put an equation but I’ll explain the whole slope equation, the slope is the number "m" that is multiplied on the x, and "b" is the y-intercept. This is called slope intercept form, the slope is calculated by finding a vertical change and a horizontal change on a graph.

Find the value of x using the measures of the two given adjacent supplementary angles. The figure is not drawn to scale.

andrey2020 [161]

Answer:

x= 42

Step-by-step explanation:

3x+ 54=180

straight angle is 180

So just solve the equation.

subtract 54 on both sides.

126=3x

divide that by 3, and you get 42.

check You answer by multiplying 42 And 3, Which basically Is 126

and then 126+54

which is then 180

I hope this Helps!

Triangles J K L and X Y Z are shown. Angles K J L and Y X Z are right angles. The length of Y X is 10. The length of hypotenuse

pickupchik [31]

ΔJKL and ΔXYZ CANNOT be congruent triangles because: the hypotenuse of one triangle is equal in length to the leg of the other triangle.

<h3>What are Congruent Triangles?</h3>

Congruent triangles are triangles whose corresponding sides are congruent to each other.

The hypotenuse of triangle JKL(KL = 10) is congruent to a leg of triangle XYZ (YX = 10). This implies that they cannot be congruent triangles.

Therefore, ΔJKL and ΔXYZ CANNOT be congruent triangles because: the hypotenuse of one triangle is equal in length to the leg of the other triangle.

In your own words, explain why C=2πr, where C is the circumference of a circle of radius r. Include a description of the number

schepotkina [342]

Answer:

Pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle's size, this ratio will always equal pi(3.1415).

There are two radii in one diameter. The formula for circumference is pi*d when using diameter which explains the two in front of the formula given by your teacher.
