19. Write Three Equivalent Fractions Todescribe The Portion Of The Stained Glasswindow That Is Gold,Need

Answers

Answer 1

Answer:

  3/5 = 6/10 = 9/15

Step-by-step explanation:

The picture shows a stained glass window that has 5 panels. The panels are presumed to be equal in size. Each represents 1/5 of the area of the window.

Three of those panels are gold. (The other two are green.) So, the fraction of the window that is gold is ...

  3 × 1/5 = 3/5

__

Multiplying numerator and denominator of a fraction by the same value gives an equivalent fraction. We can write two more equivalent fractions using 2 and 3 as multipliers:

  3/5 = (3/5)(2/2) = 6/10

  3/5 = (3/5)(3/3) = 9/15

Three equivalent fractions for the gold portion of the window are ...

  3/5, 6/10, 9/15.

Solve the system of equations by graphing.
y=−3x−4 y=x+4

Answers

I hope this helps: first when graphing y=Mx+b always start with ur y-intercept or b so in this case y = -3x + -4 u would go down 4 spaces and right three spaces or till u reach -3 on the second quadrant. For the second one you’ll do (0,0) find the slope with the coordinate given to you.

Answer:

x = -2

y = 2

Step-by-step explanation:

In addition to my explanation, I will include a graph.

Since both equations are in slope-intercept form [tex]y=mx+b[/tex], where m is the slope of the line and b is the y-intercept, we can easily plot both lines.

First you plot the first points, which are (0,-4) and (0,4).

Next, we can use rise over run to determine where our next points will go.

Rise over run is just taking the slope as a fraction and using that to move points. For example, a slope with 3/4 would mean I move my points 4 spots to the right on the x-axis and 3 up on the y-axis. Every whole number is that number with #/1, so for the first equation we go right 1 spot and down 3 spots. For the next equation we go up 1 and right one. Keep doing this until you have a line formed and find where the lines intersect, or share a point.

find the length of a 90° arc of a circle with a diameter of 10 m​

Answers

Answer:

7.85 m (3 significant figures)

Step-by-step explanation:

Formula:   arc length = [tex]2\pi r(\frac{\theta}{360} )[/tex]

The radius of a circle is half the diameter, so r = 10 ÷ 2 = 5

Therefore, arc length = 2 x [tex]\pi[/tex] x 5 x [tex](\frac{90}{360} )[/tex]

                                    = [tex]\frac{5}{2}\pi[/tex]

                                    = 7.853981634...

                                    = 7.85 m (3 significant figures)

The graph shows Dan's earnings for different hours worked. Select the terms that can be used to describe Dan's earnings

Answers

The graph is an illustration of a linear function

The term that can be used to describe Dan's earning is that he earns $10.25 per hour

How to determine the hourly rate

From the graph, we have the following ordered pairs

(x,y) = {(4,41) (7,71.75)}

The slope (m) is then calculated as:

[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{71.75 - 41}{7 -4}[/tex]

Simplify

[tex]m = \frac{30.75}{3}[/tex]

Evaluate the quotient

[tex]m = 10.25[/tex]

Hence, Dan's hourly earning is $10.25 per hour

find the area of KLMN​

Answers

Answer:

Step-by-step explanation:

Step-by-step explanation:

the first thing we notice : the quadrilateral has 2 pairs of equally long sides with 2 angles being openly 90°.

so, we are dealing with a rectangle here.

we know that one pair of the sides (NK = LM) are 24 cm long.

and we know that KL:LM = 3:4.

that means that the pair KL = MN are the shorter sides of the rectangle. and their length is according to the ratio 3/4 of NK=LM.

3/4 × 24 = 18 cm

the area of that rectangle is therefore

18 × 24 = 432 cm²

Cobalt-60 is subject to radioactive decay, and each year the amount present is reduced by 12.3%. (a) The amount of cobalt-60 present is an exponential function of time in years. What is the base of this exponential function? . (b) What is the half-life of cobalt-60? Round your answer to one decimal place. yr

Answers

Using an exponential function, it is found that:

a) The base is of 0.877.

b) The half-life of cobalt-60 is of 5.3 years.

What is an exponential function?

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

A(0) is the initial value.r is the decay rate, as a decimal, and 1 - r is the base.

Item a:

Each year the amount present is reduced by 12.3%, hence [tex]r = 0.123[/tex], and the base is:

[tex]1 - r = 1 - 0.123 = 0.877[/tex]

Item b:

This is t for which A(t) = 0.5A(0), hence:

[tex]A(t) = A(0)(0.877)^t[/tex]

[tex]0.5A(0) = A(0)(0.877)^t[/tex]

[tex](0.877)^t = 0.5[/tex]

[tex]\log{(0.877)^t} = \log{0.5}[/tex]

[tex]t\log{0.877} = \log{0.5}[/tex]

[tex]t = \frac{\log{0.5}}{\log{0.877}}[/tex]

[tex]t = 5.3[/tex]

The half-life of cobalt-60 is of 5.3 years.

Answers

Answer:

x-intercept: [tex]\bigg(\frac{5}{2}, \:0\bigg)[/tex]

y-intercept: [tex](0,\:5)[/tex]

Step-by-step explanation:

To find the x-intercept, substitute in [tex]0[/tex] for [tex]y[/tex] and solve for [tex]x[/tex].

[tex]-4x + 7 = 2y - 3[/tex]

[tex]-4x+7=2\left(\bold{0}\right)-3[/tex]

Simplify 2(0):                                          [tex]-4x+7=2\cdot \:0-3[/tex]

Subtract 0 - 3 = -3:                         [tex]-4x+7=-3[/tex]

Subtract 7 from both sides:          [tex]-4x+7-7=-3-7[/tex]

Simplify:                                         [tex]-4x=-10[/tex]

Divide both sides by -4                [tex]\frac{-4x}{-4}=\frac{-10}{-4}[/tex]

[tex]\bold{x=\frac{5}{2}}[/tex]

To find the y-intercept, substitute in [tex]0[/tex] for [tex]x[/tex] and solve for [tex]y[/tex].

[tex]-4x + 7 = 2y - 3[/tex]

[tex]-4(\bold{0})+7=2y-3[/tex]

Switch sides:                               [tex]y-3=-4\left(0\right)+7[/tex]

Simplify -4(0):                              [tex]2y-3=-0+7[/tex]

Add 3 to both sides:                  [tex]2y-3+3=7+3[/tex]

Simplify:                                      [tex]2y=10[/tex]

Divide both sides by 2:             [tex]\frac{2y}{2}=\frac{10}{2}[/tex]
