Step-by-step explanation:

There is a bag with 50 popsicles inside. 5
are red, 15 are orange, 12 are blue, 8 are
yellow and 10 are purple. If you were to
grab one popsicle from the bag, what is
the probability that it is purple?

Answers

Answer:

25%

Step-by-step explanation:

We know that there are ten purple popsicles. Together without the purple popsicles, there are 40 popsicles in total. Therefore there is a 10/40 chance to get purple. We need to turn this into a percentage so we do (10 / 40) x 100. This would equal to 25%, therefore, there is a 25% probability to get a purple popsicle.

What is 10 times something equal 24

Answers

Answer:

2.4

Step-by-step explanation:

An easy way to find this is via division.

24 ÷ 10 = 2.4 | therefore,

2.4 × 10 = 24

Answer:

2.4

Step-by-step explanation:

"something" = x

10x = 24

divide both sides by 10

10x/10 = 24/10

x = 2.4

solve the simultaneous Equation
3/x- 4/y= 1/3

Answers

Answer:

a simultaneous equation is a set of equations. you need at least another equation.

Answer:

Step-by-step explanation:

Let's solve for x.

3x−4y= 1/ 3

Step 1: Add 4y to both sides.

3x−4y+4y= 1/ 3 +4y

3x=4y+ 1/ 3

Step 2: Divide both sides by 3.

3x/ 3 = 4y+ 1/ 3

3 x= 4/ 3 y+ 1/ 9

Answer:

x= 4/ 3 y+ 1/ 9

Let's solve for y.

3x−4y= 1/ 3

Step 1: Add -3x to both sides.

3x−4y+−3x= 1/ 3 +−3x

−4y=−3x+ 1/ 3

Step 2: Divide both sides by -4.

−4y/ −4 = −3x+ 1/ 3

−4 y= 3/ 4 x+ −1/ 12

Answer:

y= 3/ 4 x+ −1/ 12

2. Hailey is flying a kite on a string 25m long. The kite is directly above Cassi who is 15m from Hailey. How high is the kite above the ground?

Use the Pythagorean theorem to solve each problem. Show Calculations.

Answers

Answer:

1) 25 miles

2) 20 m

Step-by-step explanation:

Number 1 is going to be

[tex]a^{2} + b^{2} = c^{2}[/tex] because it's a right triangle

So

[tex]24^{2}[/tex] + [tex]7^{2}[/tex] = [tex]c^{2}[/tex]

625 = [tex]c^{2}[/tex]

c = 25 mile

Number 2 uses the same process, but changing to using C instead of A

a^2 = c^2 - b^2

a^2 = 625 - 225

a = \sqrt(400)

a = 20m

24 is 3/4% of what number

Answers

24 is 3/4 of the number 32

Answer:

32

Step-by-step explanation:

Alright, so think of the "what number" as x in this case. (Or any number/symbol you choose.)

So our simple equation looks something like this:

[tex]24= x *\frac{3}{4}[/tex]

So, to find out what the "what number" would be we'd flip the fraction around/find the reciprocal and multiply 24 by it. That gives us "x" or the number we're missing.

So: [tex]24 * \frac{4}{3} = x[/tex]

Doing the simple math we get:

[tex]24 * \frac{4}{3} = 32[/tex].

32 is your answer.

Hope this helps and have a nice day! Sorry I'm not great at explaining it!

please write the correct answer

Answers

Answer:

Tamara incorrectly factored the whole expression.

Step-by-step explanation:

Note that

•21x=3·7·x;

•56xy=2·2·2·7·x·y.

Mark in bold all common factors, then GCF(21x,56xy)=7·x=7x.

Thus,

21x+56xy=7x(3+8y).

Hence, Tamara correctly found the GCF of numbers 21 and 56, but incorrectly factored the whole expression.

Yes Bus Column:

We need to find an answer for the "no taxi" section. And we have the total and the "yes taxi" section. So, the "yes taxi" section + the "no taxi" section gives you the total. Another way of saying this is total - "yes taxi"  = "no taxi"125 - 30 = 95

No Bus Column:

We need to find the total of the "yes taxi" section and the "no taxi" section. So, if we add those two sections together, we'll get the total90 + 185 = 275

Total column:

So, this column is really simple to fill out. All we're doing it adding our answers above to get one answer in each section."Yes Taxi" section: 30 + 90 = 120"No Taxi" section: 280Total section: 125 + 275 = 400We could have also done the total section by adding together 120 and 280, but we would get the same answer, anyway.
