Answer:

A= 7

B= 8

C= 3

Step-by-step explanation:

For C: 9=C*C-->C=SQRT(9)=3

For B: Some number ending in 4 is equals to B*C, C being 3. Then, the first number that fits that criteria would be B=8, as B*C=8*3=24.

For C: Some number ending in 1 equals to A*C. Then, the first number that fits that criteria is A=7, as A*C=7*3=21.

If you now multiply ABC*ABC (783*783) you'll see that all the elements in the multiplication process as carried out in the pdf are non-zero, so our answer satisfies the conditions of the problem!

What is the value of x if a rectangle has a perimeter of 50, a length of x + 5, and width of 11?

Paraphin [41]

Answer:

x = 9

Step-by-step explanation:

Perimeter = 2 * width + 2 * length

= 2*11 + 2(x + 5) = 50

2x + 10 + 22 = 50

2x = 50 - 10 - 22

2x = 18

x = 9

Which expression represents the volume, in cubic units, of the composite figure? One-third(8)(6)(6) (8)(6)(4) One-third(8)(6)(10

vaieri [72.5K]

The expression of Volume in cubic meter $\frac{1}{3}$ (8)(6)(6)+(8)(6)(4)

The correct option is (1)

<h3>What is Volume?</h3>

Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.

Volume will be,

V= Volume of rectangular pyramid + Volume of cuboid

Volume of rectangular pyramid= $\frac{1}{3}$ * base area* height

= $\frac{1}{3}$ * 6*8*(10-4)

= $\frac{1}{3}$ * 6*8*6

Volume of cuboid= l*b*h

= 4*6*8

So, Volume = $\frac{1}{3}$ * 6*8*6 + 4*6*8

= $\frac{1}{3}$ (8)(6)(6)+(8)(6)(4)

So, The expression of Volume in cubic meter $\frac{1}{3}$ (8)(6)(6)+(8)(6)(4).

ABCD is a quadrilateral inscribed in a circle, as shown below:

german

Answer:

A. (x + 16) + (6x − 4) = 180

Step-by-step explanation:

Inscribed quadrilateral has opposite angles supplementary.

m∠A + m∠C = 180°

m∠B + m∠D = 180°.

<u>Since</u>

m∠A = x + 16,
m∠B = x,
m∠C = 6x - 4,
m∠D = 2x + 16

we can use either pair of angle measures to work out the value of x and then find the value of each angle.

<u>We can verify the first option is the only correct one.</u>

m∠A + m∠C = 180°
(x + 16) + (6x − 4) = 180

Xy = –16. What is the constant of variation for this relationship?

olganol [36]

Direct variation is y=kx and inverse variation is y=k/x, in this case:

y=-16/x

So this is an inverse variation with a constant of -16

Question 6<br> Find the slope of the line passing through the points (11,-5) and (11,6)

zimovet [89]

There are two ways to approach this.

Option #1:

Use the slope formula $m = \dfrac{y_2-y_1}{x_2-x_1}$ .

$m= \dfrac{6-(-5)}{11-11} = \dfrac{11}{0}$

That value is undefined, so the slope is undefined.

Option #2:

Because the two points have the same x-value, they will be vertically above/below one another. This means your line is a vertical line and the slope of a vertical line is undefined.

Either way, your slope is undefined.
