Answer:

3/28 or [tex]\frac{3}{28}[/tex]

Step-by-step explanation:

[tex]\frac{2}7}[/tex]÷[tex]\frac{8}{3}[/tex]

to divide fractions, flip the second one and multiply them.

[tex]\frac{2}{7}*\frac{3}{8}[/tex]

2 * 3 = 6

7 * 8 = 56

[tex]\frac{6}{56}[/tex]

simplify by dividing both sides by 2

Last week Jim’s gross pay was $1,248 working 40 regular hours and 8 overtime hrs at double pay.

What was Jim's regular hourly rate?

Answers

Answer: 24


Explanation:

Total pay = gross pay + overtime pay

= 40x + 12x

= 52x

The total pay is 1,248
So

5x = 1,248

X = 1,248/52

X = 24

(Divide each side by 52)

Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (x,y) be the unknown endpoint. Apply the midpoint
formula, and solve the two equations for x and y.)
midpoint (-2, -16), endpoint (-7.-9)

Answers

Given:

One endpoint of a line segment = (-7,-9)

Midpoint of the segment = (-2,-16)

To find:

The other endpoint of the given line segment.

Solution:

Let (a,b) be the other endpoint of the given line segment.

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Using this formula, we get

[tex](-2,-16)=\left(\dfrac{-7+a}{2},\dfrac{-9+b}{2}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{-7+a}{2}=-2[/tex]

[tex]-7+a=-4[/tex]

[tex]a=-4+7[/tex]

[tex]a=3[/tex]

And,

[tex]\dfrac{-9+b}{2}=-16[/tex]

[tex]-9+b=-32[/tex]

[tex]b=-32+9[/tex]

[tex]b=-23[/tex]

Therefore, the coordinates of other endpoint are (3,-23).

Answers

Answer:

x = 12

Step-by-step explanation:

In similarity triangles angles are congruent.

∠D = ∠A

x² - 8x = 48

x² - 8x  - 48 = 0

x² + 4x  - 12x - 48 = 0

x(x + 4) - 12(x + 4) = 0

(x +4)(x - 12) = 0

x - 12 = 0     {Ignore x + 4 = 0, as measurements won't have negative values}

x = 12

Caleb started with 50 bacteria for his science experiment and they doubled in one day. Jenna also started with 50 bacteria for her experiment and after one day, her number of bacteria was equal to 50 to the second power. Choose the statement that is true for the number of bacteria after one day.



A Caleb's experiment had 100 bacteria and Jenna's experiment had 250 bacteria.



B Caleb's experiment had 100 bacteria and Jenna's experiment had 2,500 bacteria.



C Caleb's experiment had 500 bacteria and Jenna's experiment had 500 bacteria.



D Caleb's experiment had 250 bacteria and Jenna's experiment had 500 bacteria.

Answers

Answer: B

Step-by-step explanation:

The second power basically means that you multiply the number by itself that many times depending on the power, and since it's 50^2, the answer is Caleb - 100 | Jenna - 2,500. (Tip: Just multiply 50 x 50)

We notice that the first equation has a 7x7x7, x term and the second equation has a -7x−7xminus, 7, x term. These terms will cancel if we add the equations together—that is, we'll eliminate the xxx terms:

\begin{aligned} 2y+\redD{7x} &= -5 \\ +~5y\redD{-7x}&=12\\ \hline\\ 7y+0 &=7 \end{aligned}

2y+7x

+ 5y−7x

7y+0

 

=−5

=12

=7

Solving for yyy, we get:

\begin{aligned} 7y+0 &=7\\\\ 7y &=7\\\\ y &=\goldD{1} \end{aligned}

7y+0

7y

y

 

=7

=7

=1

Plugging this value back into our first equation, we solve for the other variable:

\begin{aligned} 2y+7x &= -5\\\\ 2\cdot \goldD{1}+7x &= -5\\\\ 2+7x&=-5\\\\ 7x&=-7\\\\ x&=\blueD{-1} \end{aligned}

We can check our solution by plugging these values back into the original equations. Let's try the second equation:

\begin{aligned} 5y-7x &= 12\\\\ 5\cdot\goldD{1}-7(\blueD{-1}) &\stackrel ?= 12\\\\ 5+7 &= 12 \end{aligned}

find the area of the shape below, giving your answer to 1 decimal place

Answers

Answer:the answer is 150

Step-by-step explanation:multiply 10 and 15 and you get 150

Answer:

[tex] 189.25 \: {cm}^{2} [/tex]

Step-by-step explanation:

Area of the shape = Area of rectangle + Area of semicircle.

For rectangle:

Length = 15 cm

Width = 10 cm

For semicircle:

Diameter = 10 cm

Radius = 10/2 = 5 cm

Area of the shape

[tex] = lb + \frac{1}{2} \pi {r}^{2} \\ \\ = 15 \times 10 + \frac{1}{2} \times 3.14 \times {(5)}^{2} \\ \\ = 150 + \frac{1}{2} \times 3.14 \times 25 \\ \\ = 150 + 39.25 \\ \\ = 189.25 \: {cm}^{2} [/tex]
