A box is filled with 9 red crayons, 5 blue crayons, and 8 yellow crayons.
A crayon is chosen at random from the box. Find the probability that it is a blue or a yellow crayon.
Write your answer as a fraction in the simplest form.

Answers

Answer 1

Answer:

13/22

Step-by-step explanation:

9+5+8= 22

blue or yellow= 13

probability= 13/22

Answer 2
9 plus 5 plus 8 is 22
8 plus 5 is 13
so it would be 13/22

Answer: The y-intercept (b) is 10.

Step-by-step explanation:

Use the slope and the point to help you. Plot the point (-3,4) on graphing paper or use geometry software. I use geometry software, it's easier.

You'll need to understand that the slope 2 can also be written as 2/1 (rise/run). Go up 2 units and go to the right 1 unit, then plot a point. Keep going until one of the points lies on the y-axis. The y-coordinate of that point is the y-intercept. So, the y-intercept (aka "b") is 10.

which of these would be a helpful first step in solving the equation? check all that apply. 7x - 9 = 2x + 21

Answers

Answer: E. Subtract 2x

Step-by-step explanation:

Subtracting 2x would remove a bit from both equations, giving us 5x - 9 = 12. This would make it easier now that we only have one number on a side.

Hope this helps!

Subtract 2x because you need to get the x value on one side and number on the other

What is the value of x in the figure? Enter your answer in the box.

Answers

Answer:

x = 65

Step-by-step explanation:

(2x +15)= 145

      -15      -15    subtract 15 from each side

2x = 130130/2 = 65  therefore x=65
Okay so these are vertical angles, which means that they are going to be equal to each other, aka CONGRUENT.

This means that your equation is going to be:

2x + 15 = 145

Now let us solve that equation.
You are going to subtract 15 from each side, so subtract 15 from 15, and subtract 15 from 145, meaning that your new equation is going to be:

2x = 130

Now your are going to divide each side my 2. This means you are going to divide 2x by 2 and divide 130 by 2. This means:

x= 65.

I hoped that I helped ;)

Write the equation of the line in slope-intercept form using y=mx+b​

Answers

Answer:

The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a. The form y=m(x-a) is essentially different from the other two forms and means slope m and x-intercept (instead of y-intercept) a.

The figure is made up of hemisphere and a cylinder.
what is the exact volume of the figure?
box [] cm^3

Answers

Answer:

Data: (Cylinder)

h (height) = 8 cm

r (radius) = 5 cm

Adopting:

V (volume) = ?

Solving:(Cylinder volume)

Note: Now, let's find the volume of a hemisphere.

Data: (hemisphere volume)

V (volume) = ?

r (radius) = 5 cm

Adopting:

If: We know that the volume of a sphere is , but we have a hemisphere, so the formula will be half the volume of the hemisphere

Formula: (Volume of the hemisphere)

Solving:

Now, to find the total volume of the figure, add the values: (cylinder volume + hemisphere volume)

Volume of the figure = cylinder volume + hemisphere volume

Volume of the figure = 628 cm³ + 261.6 cm³

Donna made 2 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for both necklaces was $10.20. If the beads cost $3.20 for each necklace, how much did each pendant cost?

Answers

Each pendant costs $1.90. The total costs to make the 2 necklaces (beads and pendant) is $10.20. You have to find how much the beads cost for BOTH necklaces so you would solve $3.20 x 2. You would get $6.40. So now you subtract $6.40 from $10.20 to find how much the pendant for both necklaces cost. That would be $3.80 now you just divide by 2 to find the cost of 1 pendant.

a 4000 pound car driving at 40 miles/hour has how many times the kinetic energy of another 4000 pound car driving at 10 miles/hour.

Answers

Answer = 400 I think
Explain = do 4,000 five by 40 then get a answer of 100 and then do 4,000 divid by 10 and get 400 do you see the similarities of both of these question they are the same question but just written in different ways just by adding a zero.

The comparison of the kinetic energy of the given bodies is required.

The first car has 16 times more the kinetic energy of the second car.

Kinetic energy

m = Mass of car = 4000 pound

[tex]v_1[/tex] = Initial velocity of car = 40 miles/hour

[tex]v_2[/tex] = Final velocity of car = 10 miles/hour

The mass of the car is constant so we have the relation

[tex]K\propto v^2[/tex]

Thus,

[tex]\dfrac{K_1}{K_2}=\dfrac{v_1^2}{v_2^2}\\\Rightarrow K_1=K_2\dfrac{40^2}{10^2}\\\Rightarrow K_1=16K_2[/tex]

Answers

Answer:

Scale factor is used to find the coordinates depending upon whether the scale factor value is less than one or more than one.

Step-by-step explanation:

A scale factor is a number which scales, or increases, some amount. In the condition y = Cx, C is the scale factor for x. C is likewise the coefficient of x, and might be known as the steady of proportionality of y to x.

An object is augmented if the scale factor is more noteworthy than 1. An article is decreased if the scale factor is a division, under 1.
