Answer:

$2.25

Step-by-step explanation:

First, you have to add the amount that Aaron paid. Then, subtract it from 10, which is the amount of the bill he is paying with.

5.25 + 2.50 = 7.75

10-7.75 = 2.25

Answer:

$2.25

Step-by-step explanation:

First, we will find out how much he needs to pay.

$5.25 + $2.50 = $7.75

Then, we will find the amount of change he should receive.

$10.00 - $7.75 = $2.25

33-5=28

28÷2=14

Hence, one of the number is 14.

14+5=19.

Another number is 19.

∴For checking:

19+14=33

19-14=5

Webmath is a math-help web site that generates answers to specific math questions and problems, as entered by a user, at any particular moment.

Answer:

54°

Step-by-step explanation:

In the given question we would like to solve for x .The two marked angles here are vertically opposite angles . And vertically opposite angles are equal .

So here (2x +2)° and (3x - 52)° are equal. Therefore,

[tex]\longrightarrow 2x + 2^o = 3x - 52^o\\ [/tex]

[tex]\longrightarrow 2x - 3x = -52^o -2^o \\ [/tex]

[tex]\longrightarrow -x = -54^o\\[/tex]

[tex]\longrightarrow \underline{\underline{\boldsymbol{ x = 54^o }}} [/tex]

Hence the value of x is 54°

And we are done!

Answer :

Explanation :

Here,

[tex] \longrightarrow \sf \qquad \: (3x - 52) {}^{ \circ} = (2x + 2) {}^{ \circ} [/tex]

[tex]\longrightarrow \sf \qquad \: 3x - 2x = 2 {}^{ \circ} + {52}^{ \circ} [/tex]

[tex]\longrightarrow \bf \qquad \: x = {54}^{ \circ}[/tex]

Answer:

Step-by-step explanation:

[tex]\frac{\pi r^2}{2 \pi } \times \theta=32\\\frac{1}{2} r^2 \times \theta=32\\r^2=\frac{32 \times 2}{\theta} \\r^2=\frac{64}{\theta} \\r=\frac{8}{\sqrt{\theta} }[/tex]

substitute the value of θ and solve ,you get the value of radius r

Answer:

7

Step-by-step explanation:

7 is the coefficient of X.

Reasoning? The coefficient is the number that comes before a variable. In this case, 7 is the coefficient of x.

And 2 is the coefficient of y.

Answer:

B is the better buy.

Step-by-step explanation:

A: conical container: volume = π(6/2)²*9/3 = 27π

B: cylindrical container: volume = π(6/2)²*9 = 81π

Cost per unit volume:

A: $1.75/(27π) = $0.0206

B: $3.75/(81π) = $0.0147

So B is cheaper.

B is the better buy.

Answer:

slope = -3

y-intercept = 2  

Step-by-step explanation:

The equation y = -3x + 2 is written in slope-intercept form of

y= mx +b where m is the slope and b is the y intercept.

m = -3

b= 2

Using the z-distribution, as we are working with a proportion, it is found that there is evidence that the phrasing may have influenced responses.

At the null hypothesis, it is tested if there is no difference between the proportions, that is:

[tex]H_0: p_1 - p_2 = 0[/tex]

At the alternative hypothesis, it is tested if there is difference, that is:

[tex]H_1: p_1 - p_2 \neq 0[/tex]

For each sample, we have that:

[tex]p_1 = \frac{463}{615} = 0.7528, s_1 = \sqrt{\frac{0.7528(0.2472)}{615}} = 0.0174[/tex]

[tex]p_2 = \frac{403}{585} = 0.6889, s_2 = \sqrt{\frac{0.6889(0.3111)}{585}} = 0.0191[/tex]

For the distribution of differences, we have that:

[tex]\overline{p} = p_1 - p_2 = 0.7528 - 0.6889 = 0.0639[/tex]

[tex]s = \sqrt{s_1^2 + s_2^2} = \sqrt{0.0174^2 + 0.0191^2} = 0.0258[/tex]

It is given by:

[tex]z = \frac{\overline{p} - \mu}{s}[/tex]

In which [tex]\mu = 0[/tex] is the value tested at the null hypothesis.

Hence:

[tex]z = \frac{\overline{p} - \mu}{s}[/tex]

[tex]z = \frac{0.0639 - 0}{0.0258}[/tex]

[tex]z = 2.47[/tex]

Considering a two-tailed test, as we are testing if the proportion is different of a value, and a significance level of 0.05, the critical value is [tex]|z^{\ast}| = 1.96[/tex].

Since the absolute value of the test statistic is greater than the critical value, it is found that there is evidence that the phrasing may have influenced responses.

Answer:

70

Step-by-step explanation:

if 21 is 30%, divide 21 by 3 for get 7, which is 10%. Now multiply 7 by 10 to get 70 which is 100%

Hey! 70 skittles is your answer. My work's below!

- - - - - - - - - - - - - - - - - - - -  

First, use this formula:

a certain percent (%) = a certain number (#)  

# x 100 / %

- - - - - - - - - - - - - - - - - - - -  

In this scenario...

30% = 21 (your provided numbers)

21 x 100 / 30 (the formula in action)

2,100 / 30 = 70

(2,100 is the result of 21 x 100, so divided by 30 you have 70!)

Step-by-step explanation:

Dont you do 10x9x4x4??

That is how i was tought how to do it. I dont know about you.

Answer:

80

Step-by-step explanation:

The 4 doesn't matter right now unless you were solving for area. Visualize the shape as a normal rectangle with no cut out. That would make the bottom line 10+10+10 which equals 30. The top line is the same as the bottom, so that would also be 30. Then you just have the two sides which are both 10, combined them and they would add up to 20. Perimeter is the distance around the edge of a shape. You find the perimeter by adding up the distance of all the sides. So in conclusion, you're answer will be 30+30+10+10 which equals 80.

Answer:

The answer is 2095 cubic inches

step-by-step explaination:

Now,

V = 2/3 πr³

V = (2/3) × (22/7) × (10)³ inches

V = 44/21 × (10)³ inches

V = 2.095 × 1000 inches

V = 2095 cubic inches.

Thus, The volume of bowl is 2095 cubic inches.

Answer:

i wrote an explanation and the answers below!

Step-by-step explanation:

so ill give you a few tips on these!

1/2 can be written as 0.50 since its half .

1/4 can be written as 0.25 since its fourth (i dont know how to say it loll) ?

2 1/2 is 2.50 because it has 2 and 0.5

now ill just solve the rest since i explained

3 1/4 = 3.25

20 1/2 = 20.5

10.

to solve for these you have to simplify and look for the GCF (greatest common factor)

20/4

the GCF is 4 because you can divide 4 to the numerator and the denominator, and because it is the biggest value that you can divide between them

so now you just have to simplify it

20/4 = 5

30/5 = 6

40 / 8 = 5
