Answer:

V= 936m³

Step-by-step explanation:

Formula:

Volume = L * W * H

Volume1= L * W * H

= 16 * 9 * 6

= 864m³

Volume2= L * W * H

= 6 * 2 * 6

= 72m³

Add both volumes to get total volume.

= 864m³ + 72m³ = 936m³

As a salesperson at Trading Cards Unlimited, Justin receives a monthly base pay plus commission on all that he sells. If he sells $500 worth of merchandise in one month, he is paid $410. If he sells $900 of merchandise in one month, he is paid $498.​

Answers

Answer:

Justin's salary will be $1048 when he sells $3400 worth of merchandise.

Step-by-step explanation:

If the salesperson receives a monthly base pay and the commission on the sales expression that represents his monthly pay,

y = B + C(x)

Here y = Monthly pay

B = Base pay

C = percentage of commission

x = Amount of sales done

If he sells $500 worth of merchandise in a month, he earns $410,

410 = B + C(500) -----(1)

If he sells $900 worth of merchandise in a month, he earns $498,

498 = B + C(900) ------(2)

By subtracting equation (1) from equation (2),

498 - 410 = 900C - 500C

88 = 400C

C = [tex]\frac{88}{400}[/tex]

C = 0.22

From equation (1),

410 = B + 0.22(500)

B = 410 - 110

B = $300

Therefore, expression for the monthly earning will be,

y = 300 + 0.22(x)

Justin's salary when he sells $3400 worth of merchandise in a month,

y = 300 + 0.22(3400)

y = 300 + 748

y = $1048

Therefore, Justin's salary will be $1048.

13. Find the roots of the quadratic equation by using the quadratic formula and factorization method (i) x 2 – + 10 = 0

Answers

Answer:

x = 5 or -2

Step-by-step explanation:

The general quadratic formula is expressed as;

ax²+bx+c = 0

Given

x² - 3x -10 = 0

a = 1, b = -3 and c = -10

x = -(-3)±√(-3)²-4(1)(-10)/2(1)

x = 3±√9+40/2

x = 3±√49/2

x = 3±7/2

x = 3+7/2 or 3-7/2

x = 10/2 or -4/2

x = 5 or -2

By Factorization

x² - 3x -10 = 0

x² - 5x+2x -10 = 0

x(x-5)+2(x-5) = 0

(x-5)(x+2) =0

x - 5 =0 and x+2 = 0

x = 5 or -2

What is the formula or equation for this problem I don’t understand

Answers

Answer:

B

Step-by-step explanation:

From the property of parallelogram the opposite angels are equal so < DAB = < DCB so < DAB will become 16x.

9x + 5 + 16x(<DAB) = 180 ....... because it is straight line.

25x + 5 = 180

25x = 180 - 5

25x = 175

x = 7 (it's 7 because u divide 175 by 25)

now let's substitute in the angle < DCB( 16x):-16 × 7= 112

To get < ABC lets use the property of parallelogram which says tha adjacent angles are supplementary. which means <ABC + <DCB = 180

<ABC + 112 = 180

< ABC = 180 - 112

< ABC = 68

A partial listing of monthly startup costs for a store includes $2,750 for rent, $479 for electricity, $217 for telephone and Internet service, $9,423 for employee salaries, $250 for cleaning service, and $100 for supplies. What percent of your monthly startup cost is rent?

Answers

Answer:

I think it is 20.8%

Step-by-step explanation:

The percentage of rent in the monthly startup cost is 20.8%

What is percentage?

A part of a whole expressed in hundredths. In percentage we equate the total with hundred and find the sum.

The formula of percentage is (Y/X)×100 = P%, where "X" is total , "Y" is the individual number of which we want to find the percentage and "P" is the percentage value.

According to the formula,

X ⇒ $2,750 + $479 + $217 + $9,423 +  $250 + $100 = $13,219

Y = $2,750

P = (Y/X)×100

2750/13219 =0.20803

0.20803×100=20.80%

Thus the percentage of the rent in the total monthly startup cost is 20.80%

(3) (x+4)*+(y-7)=9
(4) (x+4)*+(y-7)* = 81

Answers

Answer:

option 4

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (- 4, 7) and r = 18 ÷ 2 = 9 , then

(x - (- 4) )² + (y - 7)² = 9² , that is

(x + 4)² + (y - 7)² = 81

Sam says that the length of diagonal SQ is two times the length of diagonal OM.


Is Sam correct? Justify your answer and show all your work. Your work should state the theorem you used to find the lengths of the diagonals.


(Sorry for the low quality image)

Answers

Answer:

Sam is incorrect

Step-by-step explanation:

We can calculate the lengths of the diagonals using Pythagoras' identity.

The diagonals divide the rectangle and square into 2 right triangles.

Consider Δ SRQ from the rectangle

SQ² = SR² + RQ² = 12² + 6² = 144 + 36 = 180 ( take square root of both sides )

SQ = [tex]\sqrt{180}[/tex] ≈ 13.4 in ( to 1 dec. place )

Consider Δ ONM from the square

OM² = ON² + NM² = 6² + 6² = 36 + 36 = 72 ( take square root of both sides )

OM = [tex]\sqrt{72}[/tex] ≈ 8.5 in ( to 1 dec. place )

Now 2 × OM = 2 × 8.5 = 17 ≠ 13.4

Then diagonal OM is not twice the length of diagonal SQ

We know that there are 15 kids in total.

We specificly see that 8 of those kids like math the most.

To find percentage, divide 8 by 15.

Using a calculator you should find 53 1/3% of the students found math to be their favorite subject.

Next we need to find the percentag eof change that history is over elementary school to high school.

This might sound confusing, but this is basically just a change of 3 students to 4 students.

To find percentage, just divide 3 by 4:

Find the value of x to the nearest tenth. A. 26.3 B. 5.7 C. 9 D. 8.6

Answers

Answer:

C

Step-by-step explanation:

you have the angle, adjacent and you want to find the hypotenuse

therefore use CAH - (I drew the triangle on the bottom of the attachment )

length of A / cos(angle) = hypotenuse

7 / cos(39)=9.007

Answer:

C: 9 to the nearest tenth

Step-by-step explanation:

You  have three choices on your calculator to solve this problem. Only 1 of the three will work.

Sin(39)

Tan(39)

Cos(39)

You want the hypotenuse (x) and you are given the adjacent side. The adjacent side is the other side that makes up the reference angle other than the hypotenuse.

Cos(theta) = adjacent side / hypotenuse.    The is the function you use.

Adjacent side = 7

Cos(39) = 7 / x               Multiply both sides by x

x * Cos(39) = 7               Divide by Cos(39)

x = 7 / Cos(39)

x = 9                               Isn't that neat? It is actually 9.0073. but C is the answer.
