Answer:

company b 10,080 dollars

Step-by-step explanation:

23  number of uniforms that will result in equal costs at both companies.

Two or more expressions with an Equal sign is called as Equation.

Given that there are 25 students in the school's Pep Club.

The Pep Club can buy new uniforms from 2 different suppliers:

Company A charges $500, plus $22 per uniform.

Company B charges $360, plus $28 per uniform.

500+22x=360+28x

Subtract 360 on both sides

500+22x-360=28x

140+22x=28x

Subtract 22x on both sides

140=6x

Divide both sides by 6

x=23.3

The number of uniforms that will result in equal costs at both companies is 23.

The company A charges more than company B.

company B should the Pep Club choose

Hence, 23  number of uniforms that will result in equal costs at both companies.

Answer:

A

Step-by-step explanation:

Equation of the dotted line:

Slope: (-2-1)/(-2-0) = -3/-2 = 3/2

y = (3/2)x + 1

Region lies below the line, and the line is dotted:

y < (3/2)x + 1

We have been given two similar triangles. We are asked to find the length of segment EF.

We know that corresponding sides of similar triangles are proportional, so we will use proportion to solve our given problem.

[tex]\frac{EF}{DF}=\frac{BC}{AC}[/tex]

Upon substituting measure of our given side lengths, we will get:

[tex]\frac{EF}{1}=\frac{5}{13}[/tex]

[tex]EF=\frac{5}{13}[/tex]

Therefore, the length of segment EF is [tex]\frac{5}{13}[/tex] units.

Answer:

x = -6 ± 2sqrt(10)

Step-by-step explanation:

x^2 + 12x+3 = 7

Subtract 3 from each side

x^2 +12x = 4

Take the coefficient of x

12

Divide by 2

12/2 = 6

Square it

6^2 =36

Add this to each side

x^2 +12x +36 = 4+36

(x+6)^2 = 40

Take the square root of each side

sqrt((x+6)^2) =± sqrt(40)

x+6 = ± sqrt(40)

x+6 = ± sqrt(4)sqrt(10)

x+6 =± 2sqrt(10)

Subtract 6 from each side

x+6-6 = -6 ± 2sqrt(10)

x = -6 ± 2sqrt(10)

Answer:

(x + 6)² = 40 → x = ±2√10 - 6

Step-by-step explanation:

x²+12x+3=7 can be solved by completing the square

To do so we must first find the term we are adding to both sides of the equation by using [tex](\frac{b}{2} )^2}[/tex]

In this case, our b is 12, so plugging this into the formula we get [tex](\frac{12}{2} )^{2} =6^{2} =36[/tex]

We first need to subtract the 3 from both sides of the equation to get x²+12x=4

We then can add the 36 to both sides of the equation: x² + 12x + 36 = 4 + 36 → x² +12x + 36 = 40

Now we are able to factor the left side of the equation to get (x + 6)² = 40

To solve for x we need to take the square root of both sides [tex]\sqrt{(x+6)^{2} } =\sqrt{40}[/tex] to get x + 6 = ±2√10

Then we need to subtract 6 from both sides to get x = ±2√10 - 6

Answer:

y = - 3x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, - 7) and (x₂, y₂ ) = (2, - 10) ← 2 ordered pairs from the table

m = [tex]\frac{-10+7}{2-1}[/tex] = - 3 , thus

y = - 3x + c ← is the partial equation

To find c substitute any ordered pair into the partial equation

Using (2, - 10) , then

- 10 = - 6 + c ⇒ c = - 10 + 6 = - 4

y = - 3x - 4 ← equation of linear function

Answer:

h(x) = 10 [tex](0.4)^{x}[/tex]

Step-by-step explanation:

The exponential is of the form

h(x) = a [tex](b)^{x}[/tex]

Use the ordered pairs from the table to find a and b

Using (0, 10 ), then

10 = a [tex]b^{0}[/tex] ( [tex]b^{0}[/tex] - 1 ), thus

a = 10

h(x) = 10 [tex]b^{x}[/tex]

Using (1, 4 ), then

4 = 10 [tex]b^{1}[/tex] , hence

b = [tex]\frac{4}{10}[/tex] = 0.4

h(x) = 10 [tex](0.4)^{x}[/tex]

Answer:

Probability for flipping a coin twice and getting heads: 1/2

Probability for flipping a coin twice and getting tails: 1/2

Probability for getting heads AND tails: 0

Probability for getting heads or tails: 1/2

Step-by-step explanation:

Probability is how likely something happens. Since there is only 2 options, the probability for getting one of them would be 1/2 and getting both of them 0, because you can only get one of them. Probability for getting heads or tails would be the same. I'm not sure what your question was, so I did all possible answers. Hope this helps!

Answer:

Hamburger patty is 5.67 per ounce and the fish is 5.33 per ounce

Step-by-step explanation:

The hamburger patty has approximately 5.7 grams of protein per ounce and the fish has approximately 5.3 grams of protein per ounce.

Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

We have:

[tex]4\frac{1}{2}[/tex] ounce hamburger patty has [tex]25\frac{1}{2}[/tex] grams of protein

[tex]4\frac{1}{2}[/tex]  = 9/2

[tex]25\frac{1}{2}[/tex] = 51/2

Let's suppose each hamburger patty has x grams of protein so the value of x:

[tex]\rm x = \frac{\frac{51}{2}}{\frac{9}{2} }[/tex]

x = (51/2)×(2/9)

x = 5.66 ≈ 5.7 grams of protein

For fish Let's suppose each fish has y grams of protein so the value of y:

[tex]\rm y =\frac{32}{6}[/tex]

y = 5.3 grams of protein

Thus, the hamburger patty has approximately 5.7 grams of protein per ounce and the fish has approximately 5.3 grams of protein per ounce.

When the chords intersect inside the circle the sum of the vertical angles and the sum of the referenced arcs are the same.  Since the vertical angles are congruent, each is half the sum of the referenced arcs.

Similarly when the chords intersect outside the circle, the angle is half the difference of the arc measures.

It's the same with a tangent; in that case there's just not a part of the arc that's not counted on the side with the tangent.

OK, that's how.  Let's try some.

1.  x = (88 + 86)/2 = 87

2. x = (150 - 60)/2 = 45

3. The angle is exactly half the subtended arc,

x = 110/2 = 55

4. The referenced arc is 360 - 220 = 140 degrees and x is half, 70.

5.  Outside, half the difference, x = (90-20)/2 = 35

6.  Angle outside, inner arc 6 degrees, vertical angle is 90 degrees.

90 = (x - 6)/2

180 = x - 6

x = 186

7.  There's a special rule for this case but we can treat it as outside, little arc x, big arc 360-x,

60 = (360 - x  - x)/2

120 = 360 - 2x

2x = 240

x = 120

8. Inner arc x, outer arc is 360-140-x = 220-x.  Half the difference is 38,

38 = (220 - x - x)/2

76 = 220 - 2x

2x = 220 - 76

x = (220 - 76)/2 = 72

9.  x is formed by a tangent and a radius, so a right angle, x=90

y is subtended by a 35 degree angle so y=70

10.  Remaining triangle angle is 180 - 62 - 28 = 90.  Arc that subtends it is double, 180.  That means the long side is a diameter.

11.  Remaining triangle angle is 180 - 50 - 70 = 60. x=120, y=100, z=140

12.  Remaining arc 360 - 170 - 90 = 100.  Angles are half.

x=45, y=50, z=85

Shape B (The 2 by 12 one)

Step-by-step explanation:

Because the volume of shape B is 24 and the volume of shape A is 18.

The prism that could represent the prism that jake built is prism B.

A prism is a polyhedron comprising an n-sided polygon base, a second base which is a translated copy of the first, and n other faces, necessarily all parallelograms, joining corresponding sides of the two bases.

The volume of the prism = 24 cubic centimetres.

The volume of a cube = 1 cube centimetre

This means a total of 24 cubes would have been used to make a prism of 24 cubic centimetres volume.

So, the prism that jake built is prism B i.e. 2*18 type prism.

Hence, the prism that could represent the prism that jake built is prism B.
