Answer:
The complements of 10 are those numbers whose addition gives us the ten. In class we can call them the friends of 10 to make the vocabulary more understandable to our little students. Their learning and use is very important because they are the prelude to addition and subtraction.
Step-by-step explanation:
A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t2+48t+160 gives the height, t, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?
Answer:
t = 5 s
Step-by-step explanation:
The function that gives the height in feet of the ball t seconds after it is thrown is :
[tex]h(t)=-16t^2+48t+160[/tex]
We need to find how long will it be before the ball hits the ground. When it hits the ground, its height will be equal to 0.
So,
[tex]-16t^2+48t+160=0[/tex]
We need to solve this equation. When we solve, we get its solution as shown in the figure. We can see that t = -2 s and t = 5 s.
t = -2 s is not possible.
Hence, the ball will hit the ground before 5 seconds.

The ages of ten employees at a small company are shown below.
30, 32, 35, 35, 38, 38, 38, 40, 40, 45
If the data set were expanded to include a new employee who is 20 years old, how would the mean of the data set change?
A) The mean decreases by 2 years.
B) The mean decreases by about I .6 years.
C) The mean increases by about 1.6 years.
D) The mean does not change.
Answer:
B
Step-by-step explanation:
Before you add 20 the mean is 37.1 after you add 20 it’s 35.54.
37.1-35.54=1.56
Round 1.56 to 1.6

Answer:[tex]\boxed{ \bf x=6}[/tex]
Explanation:3(x + 3) = 18
⇒ Step 1 - Multiply everything in the brackets by 3:
3x + 9 = 18
⇒ Step 2 - Subtract 9 from both sides of the equation:
3x + 9 = 18
- 9 - 9
3x = 18
⇒ Step 3 - Divide both sides of the equation by 3.
[tex]\frac{3x}{3} = \frac{18}{3}[/tex]
x = 6
Answer: x = 3
Step-by-step explanation:
1. Distribute.
3(x+3)=183x+9=182. Subtract 9 from BOTH sides.
3x+9-9=18-93. Simplify.
Subtract 9 from BOTH sides.3x=9 is the answer.4. Divide BOTH sides of the equation by the same term.
[tex]\frac{3x}{3} =\frac{9}{3}[/tex]5. Simplify.
Cancel out the terms that are both in the numerator and the denominator.Divide the numbers.Therefore, your answer is X = 3

A taxi cab in Myrtle Beach charges $2 per mile and $1 for every person. If a taxi cab ride for two people costs $12, how far did the taxi cab travel?
Answer:
i believe 5 miles
Step-by-step explanation:
$12 - $2 (for the two people in the taxi cab since it costs $1 every person)
= $10
then to find out the number of miles they traveled since it costs $2 you can divide 10 by 2 and get 5 which means they traveled 5 mes
Answer:
with two people and $12, the cab will travel 5 miles
Step-by-step explanation:
equation:
2x + y = 12
x - total distance
y - # of people
12 - total cost
2x + 2 = 12
x = 5 miles
A bakery sells mocha cupcakes and chocolate cupcakes. One day it sold 28 mocha and
52 chocolate. What percent of the cupcakes sold that day were mocha?
Answer:
35% of the cupcakes were Mocha.
Step-by-step explanation:
So, 28 + 52 = 80 which means the question is: 28 is what percent % of 80? And 28 is 35% of 80. Hope I helped! Sorry if not. Have a wonderful day and an even better Christmas break! Remwmber to focus on the positive and give me a follow! ;) Bye!

What values of x will satisfy the inequality 4x + 2 > 10?
Answer:
x > 2
Step-by-step explanation:
4x + 2 > 10
Subtract 2 from both sides;
4x > 8
Divide both sides by 4;
x > 2
Answer:
x > 2
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Property
Step-by-step explanation:
Step 1: Define
4x + 2 > 10
Step 2: Solve for x
Subtract 2 on both sides: 4x > 8Divide 4 on both sides: x > 2Here we see that any value x greater than 2 would work as a solution to the inequality.

Can someone put this in slope intercept form
2x-3y=12
Answer:
Step-by-step explanation:
2x-3y=12
y=2/3x-4
slope =-5, y-intercept =-2
Answer:
y = -5x - 2
Step-by-step explanation:
y = mx + b
m = -5
b = -2
Step-by-step explanation:
I am not completely sure what your question is, but if you want to write an equation, you can just plug in the values for m and b to get y=-5x-2. If you wish to graph it, start at (0,-2) because that is your y-intercept. Next, move up 5 units and to the left 1 unit since the slope is negative. Now you have the point (-1,3). Connect the dots to get the graph.

A recipe for blueberry muffins states that it yields 12 muffins, with 270 calories per muffin. You instead decide to make
mini-muffins, and the recipe yields 20 mini-muffins. If you eat 7 mini-muffins, how many calories will you consume?
Answer:
If you eat 7 mini-muffins, will you consume 1134 calories.
Step-by-step explanation:
A recipe for blueberry muffins states that it yields 12 muffins, with 270 calories per muffin.
i.e.
No of muffins = 12 muffinsCalories per muffin = 270 caloriesTotal calories of standard muffins = 270 × 12 = 3240 calories
If the same amount of calories are made by 20 mini-muffins, then the total number of calories per mini-muffin will be:
3240/20 = [tex]162[/tex] calories per muffin
As you ate 7 mini-muffins.
Thus,
Your eaten calories = 162 × 7 ∵ 162 calories per muffin
= 1134 calories
Therefore, if you eat 7 mini-muffins, will you consume 1134 calories.
Joanne was hired by a florist to make large boes for holidays wreaths each roll of ribbon has 20 yards joanne used 3 1/2 rolls of ribbons to make 15 bows how many feet of ribbon did she use to make each bow
Answer: Each bow needs 4.67 yards of ribbon.
Step-by-step explanation:
We know that each roll has 20 yd.
She used 3 + 1/2 rolls, then the total length used will be (3 + 1/2) times the length of each roll, this is:
(3 + 1/2)*20 yd = (6/2 + 1/2)*20yd = (7/2)*20yd = 70 yd.
With tose 70 yards of ribbon, she made 15 bows, then the length of ribbon used in each bow will be equal to the quotient between the total length used and the number of ribbons made with it, this is:
70yd/15 = 4.67 yards
Each bow needs 4.67 yards of ribbon.

I just need to know what elevation did Winston reach during his deepest dive?
Answer: 20.2 * -2.5ft = -50.5ft
Hence, Winston reach -50.5 feet during his deepest dive.
If your question was this: On Wednesday at 9 a.m., Winston went diving. Near the beach, the ocean’s surface was at an elevation of -2.5 feet. During his deepest dive, Winston reached an elevation that was 20 1/5 times the elevation of the ocean’s surface. What elevation did Winston reach during his deepest dive? Then that should be your answer.... I had this question too, and this is what i got....
