Answer:

120 minutes

Step-by-step explanation:

We know that Toby has spent 25% of his total allotted time, or 30 min on gaming. To find how long Toby is allowed to spend in total, we must understand how long 100% of his total alloted time is.

Notice how 100% is 4 times 25%.

All we have to do is scale 30 min by 4 to find how long 100% is:

[tex]4*30=120[/tex] minutes.

Toby is allowed to spend 120 minutes total on his console in a week.

I hope this helps! Let me know if you have any questions :)

Answer:

66 square inches

Step-by-step explanation:

Area of the trapezoid = ½(a + b) × h

Where,

a = 14 inches

b = 8 inches

h = 6 inches

Plug in the values into the trapezoid area formula

Area of the trapezoid = ½(14 + 8) × 6

= ½(22) × 6

= 11 × 6

Area of the trapezoid = 66 square inches

Answer:

The answer is the second option

Step-by-step explanation:

V=Bh

Answer: 3 1/2 units^3

Step-by-step explanation:

Use the formula V = lwh to find the volume.

V = (2) (1) (7/4)

V = 2 (7/4)

V = 7/2 or 3 1/2 cubic units

Answer:

5 years

Step-by-step explanation:

To determine the number of years needed for the company to process a certain amount of milk, we use the given function which relates the number of years, x, and the gallons of milk, y. We simply substitute the number of gallons to y and solve for x.  

y = x^6 − 9x^4 + 70x^2

630 = x^6 − 9x^4 + 70x^2

Solving for x, we will have

x = 4.8866 years or approximately 5 years

Hope this answer helps you :)

Have a great day

Answer:

The fraction 53 9 is equivalent to 5 8 9.

Step-by-step explanation:

This fraction is a improper fraction once the absolute value of the top number or numerator (53) is greater than the absolute value of the bottom number or denomintor (9). So, the equivalent fraction is a mixed number which is made up of a whole number (5) and a proper fraction ( 8 9 ).

[tex]53 \frac{9}{10}[/tex]

53.9 can be split into 53 and .9

53 is the whole number

.9 is in the tenths place so it can be written out of 10: [tex]\frac{9}{10}[/tex]

It doesn't need to be simplified leaving us with 53 [tex]\frac{9}{10}[/tex]

Answer:

a)   [tex]P(S)=\frac{15}{28}[/tex]

b)   [tex]P(D)=\frac{13}{28}[/tex]

Step-by-step explanation:

From the question we are told that:

Bag A   [tex]W=4\\\\ Q=3[/tex]

Bag Q   [tex]W'=5\\\\ Q'=2[/tex]

Generally the equation for Probability of drawing W&B balls is mathematically given by

Bag A

[tex]P(W)=\frac{4}{7}P(Q)=\frac{3}{7}[/tex]

Since Ball is drawn and added to Bag Q

Bag Q

[tex]P(W)'=\frac{6}{8}\\\\ Q(B)'=\frac{2}{8}[/tex]

a)

Generally the equation for Probability of being the same is mathematically given by

[tex]P(S)=(P(W)*P(W'))+(P(B)*P(B)')[/tex]

[tex]P(S)=(\frac{4}{7}*\frac{6}{8})+(\frac{3}{7}*\frac{2}{8})[/tex]

[tex]P(S)=\frac{15}{28}[/tex]

b)

Generally the equation for Probability of NOT being the same is mathematically given by

[tex]P(D)=P(W)+P(B)'+(P(B)*P(W'))[/tex]

[tex]P(D)=(\frac{4}{7}*\frac{2}{8})+(\frac{3}{7}*\frac{6}{8})[/tex]

[tex]P(D)=\frac{13}{28}[/tex]

Answer:

The answer is "14.8".

Step-by-step explanation:

[tex]n = 30\\\\ k = 3\\\\dfE = n-k \\\\[/tex]

       [tex]= 30-3 \\\\= 27[/tex]

[tex]SSE = 399.6 \\\\MSE = \frac{SSE}{dfE}[/tex]

          [tex]= \frac{399.6}{27} \\\\ = 14.8[/tex]

x= 13.3

Answer:

answer is 230

Step-by-step explanation:

they need more than 800 so u take 800-571 which is 229 u then add one because u need at least one more than 800 which is 230.

Answer:

230.  

Step-by-step explanation:

You need more than 800 so you take 800 and talk away 71 which is 229, and then add 1 because you need at least one more than 800 , and you get an answer 230.

Answer:

The reason why it isnt true is because you cannot combine exponents that have different bases.

Step-by-step explanation:

So, with the problem shown below, it is [tex]3^5*2^4[/tex]

This cannot be multiplied.

To get [tex]6^9[/tex], you would need 6^4*6^5

So basically, its like ths:

If two exponents have to same base, they can be added together. THis adds the exponents, but leaves the bases the same.

If two exponents have different bases, they cannot be added together. You would have to distrubute both the numbers exponents then multiply them together.

For instance, with [tex]3^5*2^4[/tex], you would have to make it 243+16

This would equal 259.

As we can see, [tex]6^9[/tex] is over 10 million, much bigger than this.

I hope this makes sense and helps!

Answer:

Perimeter of figure = 68 centimeter

Step-by-step explanation:

Given information:

Width of side = 12 centimeter

Length of side =  22 centimeter

Find:

Perimeter of figure

Computation:

Perimeter of rectangle = 2[l + b]

Perimeter of figure = 2[Width of side + Length of side ]

Perimeter of figure = 2[12 + 22]

Perimeter of figure = 2[34]

Perimeter of figure = 68 centimeter

Answer:

[tex]y =120*1.1^x[/tex]

[tex]r = 10\%[/tex] --- Percentage increase

Step-by-step explanation:

Given

Let

[tex]x \to months[/tex]

[tex]y \to mice[/tex]

So, we have:

[tex](x_1,y_1) = (0,120)[/tex] --- Monday

[tex](x_2,y_2) = (1,132)[/tex] --- One month later

Required

The function

The function is represented as:

[tex]y = ab^x[/tex]

In [tex](x_1,y_1) = (0,120)[/tex], we have:

[tex]120 =a * 1[/tex]

[tex]120 =a[/tex]

Rewrite as:

[tex]a = 120[/tex]

In [tex](x_2,y_2) = (1,132)[/tex], we have:

[tex]132 = a * b^1[/tex]

[tex]132 = a * b[/tex]

Substitute [tex]a = 120[/tex]

[tex]132 = 120 * b[/tex]

Solve for b

[tex]b = \frac{132}{120}[/tex]

[tex]b = 1.1[/tex]

Recall that:

[tex]y = ab^x[/tex]

Hence, the function is:

[tex]y =120*1.1^x[/tex]

To get the monthly percentage increase (r), we have:

[tex]y = a(1 + r)^x[/tex]

Compare to: [tex]y = ab^x[/tex]

So:

[tex]1+r =b[/tex]

Make r the subject

[tex]r = b-1[/tex]

[tex]r = 1.1-1[/tex]

[tex]r = 0.1[/tex]

Express as percentage

[tex]r = 0.1*100\%[/tex]

[tex]r = 10\%[/tex]

Answer:

100π

Step-by-step explanation:

Area of a circle formula: πr²

The radius would be half of 20 m

So the radius, r is 10 m

Plug that in

πr²=π·10²=100π

Answer:

f(x) = (x − 1)(x − 2)(x − 3)

Step-by-step explanation:

through the x axis at one; x = 1    factor (x - 1)

through the x axis at two; x = 2    factor (x - 2)

through the x axis at three;  x = 3    factor (x - 3)

f(x) = (x − 1)(x − 2)(x − 3)

Answer:

[tex]y=-x+16[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

y=x-9

Rewrite the equation

y=1x-9

Now, we can identify clearly that the slope of the line is 1. The negative reciprocal of 1 is -1, so therefore, the slope of a perpendicular line would be -1. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-1x+b\\y=-x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-x+b[/tex]

Plug in the given point (7,9) and solve for b

[tex]9=-7+b[/tex]

Add 7 to both sides to isolate b

[tex]9+7=-7+b+7\\16=b[/tex]

Therefore, the y-intercept is 16. Plug this back into [tex]y=-x+b[/tex]:

[tex]y=-x+16[/tex]

I hope this helps!
