Answers

Answer 1

Answer:

P(1.5, 3.5)

Step-by-step explanation:

We need to find the average of the x and y coordinates. We do this by adding the two values, then dividing by two:

P(x1 + x2/ 2, y1 + y2/2) = P(1 + 2/ 2, 2 + 5/ 2) = P(3/2, 7/2) = P(1.5, 3.5)

These are our coordinates!

The value of 'r' in the expression 24(34 + r) = 1200 is 16.

What are the basic properties of arithmetic laws of operations?

There are three types of basic arithmetic laws of operation.

Commutative law for addition and multiplication states,

a + b = b + a.

a×b = b×a.

Distributive law states,

a(b ± c) = ab ± ac.

Associative law states,

a + (b + c) = (a + b) + c.

Given, An expression 24(34 + r) = 1200.

First, we'll distribute LHS,

24×34 + 24×r = 1200.

816 + 24r = 1200.

24r = 1200 - 816.

24r = 384.

r = 384/24.

r = 16.

Lon is selling gift baskets at a craft fair. His costs are $75 for the table and $12 per basket. He sells each basket for $20.

1. Let b equal the number of baskets. Which expression represents Lon's costs? *
A- 12b - 75
B- 12b +75
C- 20b - 75
D- 20b -12b

2. How many baskets must be sold to make a profit? Solve this inequality to find out. 20b > 12b + 75 (hint: remember it's asking to make a profit) *

A- fewer than 9
B- fewer than 10
C- at least 10
D- more than 12

Answers

Answer:

1. B

2. D

Step-by-step explanation:

1. Lon's cost would be the $12 per basket times how many baskets he sells, in this case b plus the cost of the table. Lon's expression is 12b + 75

2. He needs a profit and the only way he could make that profit is if he sells more than 12.

20b > 12b + 75

20 (12) > 12 (12) + 75

240 > 140 + 75

240 > 215

Mindy makes 6 dozen chocolate chip cookies.
She takes 20 minutes to make all the cookie batter, and then she puts the cookies in the oven for 8 minutes per dozen.
To find how much time Mindy takes to make all the cookies, identify the hidden question.

Answers

You have to find how much time it took to bake 6 dozen cookies. 6 x 8 = 48 min
Then add the 48 min to the 20 min it took to make the batter. 48+20= 68 min or 1 hr 8 min

c - 12 = -14
and
7 + x = -1
plz help thank you

Answers

Answer: x= -2, c= -8

Step-by-step explanation: To solve the first equation, move the 12 over to the right side. To do this, do the oposite operation. So add 12 on both sides. The 12 on the left side cancels out, and you are left with x= -14+12. X=-2. Do the same thing for the next equation. Subtract 7 from the left side and the right side. C= -1-7. C= -8

C=-2
C=-8

Explanation: move -12 Away from C side to -14 but make it opposite of -12 so it’s +12 so c=-14+12 you get c=-2 and check by setting it up like -2-12=-14

Answer:

  y = 2x + 8

Step-by-step explanation:

You can see that the line crosses the y-intercept at 8 which is point (0, 8). From that y-intercept point you rise 2 then run 1 to get to point (2, 12), this rise over run is your slope 2/1 or simply 2.

y = mx + b

m is your slope

b is your y-intercept

Answer:

4/7 > x > -11/7

Step-by-step explanation:

First, add -4/3 to all parts

then divide all parts by -7/3

so, We need to separate it into two inequalities

[tex] \frac{4 - 7x}{3} > 0[/tex]

[tex] \frac{4 - 7x}{3} < 5[/tex]

then we solve for x,

[tex] \frac{4 - 7x}{3} > 0 = x < \frac{4}{7} [/tex]

[tex] \frac{4 - 7x}{3} < 5 = x > - \frac{11}{7} [/tex]

so we ended up like this

[tex]x = ( - \frac{11}{7} \frac{4}{7})[/tex]

Answers

9514 1404 393

Answer:

  15/40

Step-by-step explanation:

The difference between denominator and numerator in 3/8 is 8-3 = 5. In order to get an equal-value fraction with that difference being 25, each of the numbers must be multiplied by 5:

  3/8 = 15/40

The number is 15/40.

What is the slope of a surface having a rise of 5 feet and a run of 0 feet?

Answers

Answer:  The slope is "undefined."

Step-by-step explanation:  In math, division by 0 is undefined-- like you can't do it  

For slope, you need to divide rise/run.  If the run is 0, so undefined.

In real life, this surface would be like a wall or a door. They don't have a slope if they're constructed properly!

Bonus: ∠2 = 112°, ∠4 = 112°, ∠8 = 112°, ∠1 = 68°, ∠3 = 68°, ∠5 = 68°, ∠7 = 68°

Step-by-step explanation:

1. Angles 1 and 2 are supplementary because they form a straight line (180° angle) together.

2. Angles 1 and 5 are corresponding because their places (and angle measures) match.

3. Angles 2 and 5 are not alternate exterior angles because angle 5 is not on the outside area of the parallel lines.

4. Angles 4 and 6 are alternate interior angles because they are on opposite sides of the transversal and are both in the inside area of the parallel lines.

5. Angles 7 and 2 are not corresponding because their places (and angle measures) do not match.

6. Angles 3 and 6 are interior angles on the same side of the transversal because they are both in the inside area of the parallel lines and are on the same side of the transversal.

7. Angle 3 is not congruent to angle 8 because they do not have the same angle measures.

8. Angles 3 and 7 are corresponding angles because their places (and angle measures) match.

9. Angles 8 and 2 are alternate exterior angles because they are on opposite sides of the transversal and are outside areas of the parallel lines.

Bonus: If angle 6 has a measure of 112°, then the angle that supplements it has a measure of 68° (112 + 68 = 180). It also goes for the other angles that are congruent to angle 6.

Hope this helped :)
