Answers

Answer 1

Answer Using the method of alligation. 40.0= 20/(10/20) qts of 50% solution to add to your 20 qts of 20% solution. 60.0= (20+40.0) qts of the final 40% solution.

The probability is an "out of" statement. meaning out of all 6 marbles if 2 are red how what is the probability of choosing a red marble the answer is 2 out of 6 or 1/3 or 0.3333333etc. For green the probability is 1 out of 6 or 1/6 or 0.16666666etc

Jerry had k pencils. darcy and leonard then gave jerry an additional x pencils each. which expression could represent the number of pencils jerry has now?

Answers

Answer:

[tex]k[/tex]+([tex]x[/tex]×[tex]x[/tex])

Step-by-step explanation:

k is the number of pencils jerry has, and x is the number of pencils darcy and leonard gave him EACH. So you need to multiply 'x' x2 to get the total ammount of pencils they gave him, then add 'k' to know how much in total he has now.

Answer:

3x-2 = 4 or x = ²/3

Step-by-step explanation:

we have full bars of X's so that represents 3 because we have 3 of them and we subtract the 2 (-1)'s we also have and since it is an equation it is supposed to equal something so in this case it equals 4 (1)'s .

Answers

Answer:

D  Volume = 4/3

If the diameter is 3 inches the radius will be 1.5.

If you plug that in you get

V = 4/3

V=14.137

Step-by-step explanation:

hope this helps have a good day :) ❤

Volume = 14 (rounded to the nearest whole number)

Volume = 4/3 pie r^3

If the diameter is 3 inches the radius will be 1.5.

If you plug that in you get

V = 4/3 pie 1.5^3

V=14.137

The two prisms below are similar. What is the value of x?
24
4
16
A. 4
B. 24
C. 16
D. 1

Answers

Answer:

A

Step-by-step explanation:

Since the prisms are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{16}{4}[/tex] = [tex]\frac{x}{1}[/tex] ( cross- multiply )

4x = 16 ( divide both sides by 4 )

x = 4 → A

The value of x on the prism is 4.

What are Similar Figures?

Similar figures are those figures which are having the same shape, but the sizes are different.

Given are two prisms.

We have to find the length of x.

Given that they are similar.

So the ratio between their dimensions is equal.

So,

x / 1 = 16 / 4

x = 4

Hence the value of x is 4.

A tax of 7% was added on to the cost of a meal. If the tax paid was $1.40, what was the cost of the meal?

Answers

Answer:

The cost of meal is: $20

Step-by-step explanation:

Given

Percentage of tax = 7%

Also given that the amount of tax is $1.40

Let x be the price of meal

Then the tax will be 7% of x

It can be written mathematically as:

[tex]1.40 = 7\%\ of\ x[/tex]

We will simply solve this equation to get the price of meal

So,

[tex]1.40 = 0.07*x\\x = \frac{1.40}{0.07}\\x = 20[/tex]

Hence,

The cost of meal is: $20

A bag contains 2 red,5 blue,6 yellow, and 3 green crayons. What is the probability of selecting a red crayon, then without replacing it selecting an odd number that is (red, then green)
A.0
B.0.25
C.01
D.0.025

Answers

Answer: D.0.025

Step-by-step explanation:

Given: A bag contains 2 red,5 blue,6 yellow, and 3 green crayons.

Total crayons: 2+5+6+3=16

Probability of getting red crayon= [tex]\dfrac{\text{Number of red crayons}}{\text{Total}}[/tex]

[tex]=\dfrac{2}{16}=\dfrac18[/tex]

Without replacement, the probability of getting green crayon = [tex]\dfrac{\text{Number of green crayons}}{\text{Total}-1}[/tex]

[tex]=\dfrac{3}{15}=\dfrac15[/tex]

Required probability P(red then green)= [tex]\dfrac18\times\dfrac15=\dfrac1{40}=0.025[/tex]

Hence, correct option is D.0.025
