Let b represent the hours Liz spends babysitting. Let t represent the number of hours she spends tutoring. Given that Liz can work at most 12 hours per week, write an inequality that models the number of hours she spends babysitting and tutoring in a week.

Answers

So if b is hours for babysitting, and t is for tutoring she works 12 hours so it would be 12=b+t

Answer:

b+t < 12 (< has a line under it)

Step-by-step explanation:

Liz can work at most 12 hours per week. So, add the number of hours she spends babysitting, b, and the number of hours she spends tutoring, t, in a week, and represent the sum as less than or equal to 12:

b + t < 12

Answers

Answer:

62.22%

Step-by-step explanation:

First, find how many total marbles there are:

12 + 11 + 17 + 5

= 45

Then, find how many marbles that are not blue:

12 + 11 + 5

= 28

Then, divide 28 by 45, and multiply by 100

(28/45) x 100

= 62.22% is the probability of not choosing a blue marble

Y/T = 28/45 = 62%
Y=yes
T=total

Answers

[tex]3^{2} + 12 = 9 + 12 = 21[/tex]

The answer is 21.

Answer:

The correct answer is 21.

Step-by-step explanation:

To solve this problem, we simply substitute 3 for a in the expression.

Given the expression,

a^2 + 12

we should replace "a" with 3, as denoted by the problem, giving us:

(3)^2 + 12

Now, we simplify using the order of operations.  PEMDAS tells us that we should simplify what is in the parentheses first because it has an exponent.

9 + 12

Now, we can just add the two remaining terms together, giving us:

21

Therefore, the answer is 21.

Write the Linear Equation in Point-Slope Form for a line that has a slope of
-10 and passes through the point (8,2). *

Answers

Answer:

y = -10x + 82

Step-by-step explanation:

Plug in the slope and point into y = mx + b to solve for b:

y = mx + b

2 = -10(8) + b

2 = -80 + b

82 = b

Then, plug b and the slope into y = mx + b

y = -10x + 82 is the equation in point slope form.

Solve for the length of BC

Answers

Answer:

BC= 9cm

Step-by-step explanation:

You'll need to use the Pythagorean theorem:

a^2 + b^2 = c^2

12^2 + b^2 = 15^2

The slanted side of the triangle is always going to be 'c' because it is the longest side of the triangle.

Now simplify:   144 + b^2 = 225

I got these numbers because 12^2= 144 and 15^2= 225

Subtract.   225 - 144 = 81

Now find the square root of 81. The answer is 9.

x + 2y = -2
solve for y in the first equation
y = 6 - 2x
plug y into the second equation
x + 2(6 - 2x) = -2
-3x + 12 = -2
-3x = -14
x = 14/3

Tanya is 6 times younger than her great-grandfather. If a zero is placed between the digits of her age, it will read as the age of her great-grandfather. How old is Tanya?

Answers

Answer:

Tanya is 18 years old.

Step-by-step explanation:

In order to determine this, we assume the following

x =  tens digit of the age of Tanya, and also the hundreds digit of Tanya's great-grandfather age

y = units digit of the age of Tanya, and also the units digit of Tanya's great-grandfather age

Therefore, we have:

10x + y = (1 / 6) * (100x + y)

Multiply both sides by 6, we have:

[10x + y] * 6 = [(1 / 6) * (100x + y)] * 6

60x + 6y = 100x + y

Collect the like terms, we have:

6y - y = 100x - 60x

5y = 40x

Divide through by 5, we have:

y = 8x

That is,

8x = y

Note that x and y has to be single digits. This can only be obtained only when x = 1 and y = 8. And given how x and y is defined above, we have:

The age of Tanya = 18

This can be verified as follows:

18 = 108 / 6

18 * 6 = 108

108 = 108

Therefore, Tanya is 18 years old.

Step-by-step explanation:

The model has a length of 15 cm.

Now, we are told that the scale is 1:500. This means that 1 unit is represents 500 cm on the model.

Since the length on the model is 15 cm which is 15 units, then the true length would be;

15 × 1/500 = 0.03 cm

Therefore, the true length is 0.03 cm.
