PLEASE HELP I DONT UNDERSTAND!!! Mason works in a cell phone store where he earns a base salary of $105 per a day plus 15% of his sales. He earned $600 by working on a Saturday and Sunday and sold the same amount on both days. Select all of the statements that help explain how to find his sales for each day.

A. Mason's base salary is $105, so over the 2 days he earned $210.


B. Subtract $210 from $600 to find he made $390 on sales.


C. Mason's base salary is $600, so over the two days he earned $1,200.


D. Multiply $390 by 0.15 to find he sold $58.50 worth of cell phones. Divide $58.50 by 2 to find he sold $29.25 worth of cell phones each day.


E. Divide $390 by 0.15 to find he sold $2,600 worth of phones. Divide $2,600 by 2 to find he sold $1,300 worth of phones each day.


F. Add $1,200 to $105 to find Mason made $1,305 on phone sales.

Answer:

70

Step-by-step explanation:

Opposite Angles are supplementary in cyclic quadratlerials.

Answer:

6

Step-by-step explanation:

Answer:

a. C(x(h)) = 600h + 500

b. C(8) = 5,300

c. See below.

Step-by-step explanation:

a. C(x(h)) = C(30h) = 20(30h) + 500 = 600h + 500

b. C(8) = 600(8) + 500 = 5,300

c. 5,300 is the cost of making the number of shovels that can be made in 8 hours.

Answer: 41 meters squared

Step-by-step Explanation:

First, just find the area of the rectangle:

7 x 5 = 35

Then first the area of the triangles, 3 x 2/2 x 2 = 6

all together the surface area is 41 meters squared.

Answer:

55 degrees

Step-by-step explanation:

All the angles of a triangle should add up to 180 degrees.

So, if you add angles 1 and 2 together and subtract them from 180 it will result in the unknown angle.

35+ 90 + x = 180

125 + x = 180

x = 55

Answer:

The probability that two of them

die is 0.257

Step-by-step explanation:

From the question, we have that the mortality rate is 0.1

So the probability that they will survive is 1-0.1 = 0.9

Now, we want to check that two will die

We are going you use the Bernoulli approximation of the Binomial theorem as follows

= nCr * p^n * q^(n-r)

where n = 16

r = 2

P = 0.1

q = 0.9

Substituting these values;

14 C 2 * 0.1^2 * 0.9^12

= 0.257

Step-by-step explanation:

➡(5x-2)(5x+2)=12

➡5x^2-(2)^2=12

➡25x^2-4=12[/tex]

➡25x^2=12+4=16

Step-by-step explanation:

[tex] \rm \mapsto \: (5x - 2)(5x + 2) = 12 \\ \rm \mapsto \: 5x(5x + 2) - 2(5x + 2)=12 \\ \rm \mapsto \: {25x}^{2} + 10x - 10x - 4 =12\\ \rm \mapsto \: {25x}^{2} - 4=12 \\ \rm \mapsto \:25x^2=12+4 \\ \rm \mapsto \: 25x^2=16[/tex]

Answer:

m<AOB = 50°

Step-by-step explanation:

<ACB = 25° is an inscribed angle of the circle.

<AOB is a central angle of the circle.

Thus, based on the inscribed angle theorem which states that an inscribed angle is ½ the measure of the central angle, therefore:

m<ACB = ½(m<AOB)

Substitute

25° = ½(m<AOB)

Multiply both sides by 2

2*25 = m<AOB

m<AOB = 50°

Answer:

([tex]GS[/tex]) || ([tex]EA[/tex])

Step-by-step explanation:

When two lines are parallel, all four angles formed by the intersection of the two lines are right angles, meaning their angle measures are (90°). This means that alternate interior angles are congruent because all alternate interior angles measures equal (90°). Therefore, by the alternate interior angles converse theorem, lines ([tex]GS[/tex]) and ([tex]EA[/tex]) are parallel.

The alternate interior angles converse theorem states if two angles are congruent and they have the relation of being a part of two lines intersected by a third line, then the two non-intersecting lines are parallel.

Answer:

-35

Step-by-step explanation:

[tex]-5 = \frac{1}{7}a\\-35 = a[/tex]

I got this by multiplying the numerator by 7. This allows the denominator to be the same as the numerator, thus equalling 1.

1 * a = a

Answer: a = -35

Step-by-step explanation:

1. -5 = 1/7(a) || GIVEN

2. -5 * (7) = (7) * 1/7(a) || Isolate "a" on one side of the equation by multiplying 7 to the other side.

3. -35 = a

Answer:

x = 58°

Step-by-step explanation:

ABCD is a cyclic quadrilateral and opposite angles are supplementary , so

∠ DAB = 180° - 121° = 59°

The angle between a tangent and a chord is equal to the angle in the alternate segment, then

∠ ABD = 63° , thus

x = 180° - (59 + 63)° = 180° - 122° = 58°

Answer: $800 because if you have a light that is $2,000 and it loses %10 of its price per month, and June is 4 months away, then it is only $800.

4 x .1 = .4 so $2,000 x .4 = $800

A=774

Answer:

B

Step-by-step explanation:

You find the multiplicity by looking at the power of the original root. You can imagine it as [tex](x+7)^1(x+3)^2[/tex]. Now set those equal to 0 to find the value of them as roots.

[tex]x+7=0\\x+3=0[/tex]

Solve them both and you get:

[tex]x=-7\\x=-3[/tex]

Now as we saw in the origin of the roots above that (x + 7) was raised to the first power. That means it has a multiplicity of one, which also means it crosses when it reaches the x-axis. (x + 3) however had a multiplicity of 2, since it was squared. That means that (x + 3) will touch and turn the x-axis.

Therefore the answer is B since that agrees with everything we said.

Answer:

73.36

Step-by-step explanation:

A can of juice is 6 inches high

The diameter is 4

Radius= 4/2

= 2

Hence the volume of the can (cylinder,) can be calculated as follows

= πr^2h

= 3.142× 2^2 × 6

= 73.36 inches

Answer:

14.2 units

Step-by-step explanation:

Here x increases by 11 from -5 to +6.  This is the length of the horizontal leg of a right triangle.  Then y decreases by 9 from 7 to -2.  This is the length of the vertical leg.  The hypotenuse of this triangle may be found using the Pythagorean Theorem:

11^2 + 9^2 = (hypotenuse)^2, or

hypotenuse = √(121 + 81) = √202 ≈ 14.2 units

Answer:

≈ 14.2

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (- 5, 7) and (x₂, y₂ ) = (6, - 2)

d = [tex]\sqrt{(6+5)^2+(-2-7)^2}[/tex]

  = [tex]\sqrt{11^2+(-9)^2}[/tex]

  = [tex]\sqrt{121+81}[/tex]

  = [tex]\sqrt{202}[/tex]

  ≈ 14.2 ( to the nearest tenth )
