Answer:
1 1/2 one and a half
Step-by-step explanation:
So we know 100% is 1 whole so we already know we have 1. 50% is half and if we put 1 and 1/2 together is gives us 1 1/2 one and a half hope this answered your question.
Answer:
1.50 is 150% in decimal form and 1 1/2 is in fraction form
Step-by-step explanation:
150 is over 100 so equals 1 whole
50 is left over
50 is half of 100 so 1/2 is the same fraction

-3, -2,-1, 0, 1, 2, 3, are called_______
Answer: Integers
Step-by-step explanation: To help introduce the set
of integers, let's use the number line shown below.
Notice that on a number line, 0 is in the middle, all numbers to the
left of 0 are negative, and all numbers to the right of 0 are positive.
The set of integers includes the set of whole numbers, {0, 1, 2, 3, ...},
which appear at 0 and to the right of 0 on the number line.
The set of integers also includes {-1, -2, -3, ...} which
appear to the left of 0 on the number line.
So the ste of integers can be written as {...-3, -2, -1, 0, 1, 2, 3...}.
Answer:
Integers
Step-by-step explanation:
a positive (+) or negative (-) number with no fractional parts. zero (0) Is also an integer
Examples: -3, 3

Help please also give an explanation
Answer:
The answer is option AStep-by-step explanation:
[tex] \frac{a + bc}{wd + f} = g[/tex]First of all cross multiply
That's
g( wd + f ) = a + bc
Multiply the terms at the left side of the equation
We have
gwd + fg = a + bc
Send fg to the right side of the equation
That's
gwd = a + bc - fg
Divide both sides by dg to make W stand alone
[tex] \frac{gwd}{dg} = \frac{a + bc - fg}{dg} [/tex]We have the final answer as
[tex]w = \frac{a + bc - fg}{dg} [/tex]Hope this helps you

kelly bought some stuffed animals for 6.49 each she also got a box fo chocolate for 8.32 she paid a total of 27.79 to write an equation to find how many stuffed animals kelly purchased
Answer:
3
Step-by-step explanation:
She only bought one chocolate so you will subtract 8.32 from her total, 27.79, when you do that you will get 19.47. You do that so you can know the total of the stuffed animals by them self. Then all you have left in the total is her stuffed animals so you divide 19.47 by 6.49, when you do that you get three, so that means that she got three stuffed animals.
Step-by-step explanation:
thats the answer right there

A jar contains 2 caramels, 7 mints, and 16 dark chocolates. What is the probability of choosing a dark chocolate, eating it and then choosing a caramel?
Answer: dark chocolate 16/25 carmel 1/12
Step-by-step explanation:
there are 16 dark chocolates
to find the probability you have to add up all of your numbers
2+7+16= 25
so the probablity of drawing a dark chocolate is 16/25
repeat the steps but subtract 1 from the total since you ate one you didn't put it back.
so the probability of drawing a carmel is 2/24 or simplified 1/12
given the piece wise function show below, select all that are true
Answer:
Option (C) and (D)
Step-by-step explanation:
Given piecewise function is,
f(x) = 2x, x < 1
5, x = 1
[tex]x^{2}[/tex], x > 1
Option (A),
x = 5 means x > 1
So the function will be,
f(x) = [tex]x^{2}[/tex]
f(5) = (5)²
= 25
Therefore, f(5) = 1 is not correct.
Option (B),
x = -2 means x < 1
f(x) = 2x will be applicable.
f(-2) = 2(-2) = -4
Therefore, f(-2) = 4 is not correct.
Option (C)
For x = 1,
f(1) = 5
Therefore, f(1) = 5 is the correct option.
Option (D)
x = 2 means x > 1 and the function defined will be,
f(x) = x²
f(2) = 2²
= 4
Therefore, f(2) = 4 will be the correct option.
Options (C) and (D) will be the answer.
y^2+3y-10=0 please solve
The Answer is: y=2,5
Answer:
y = -5
y = 2
Step-by-step explanation:
Find 2 factors of -10 that add up to 3
This will be 5 and -2
So, we can factor this:
y² + 3y -10 = 0
(y + 5)(y - 2) = 0
Set each factor equal to 0 and solve:
y + 5 = 0
y = -5
y - 2 = 0
y = 2
So, the solutions are y = -5 and y = 2

We have two varieties of concrete that we can mix together. One is 5% water and 95% concrete mix, and the other is 20% water and 80% concrete mix. We want to end up with 30 pounds of a result that is 10% water and 90% concrete mix. Determine how many pounds of each variety we need.
Answers:
20 pounds of the 95% concrete mix10 pounds of the 80% concrete mix=================================================
Explanation:
x = amount of the 95% concrete mix
y = amount of the 80% concrete mix
Type A mix has 95% concrete. If we have x pounds of this, then 0.95x pounds is pure concrete. Type B mix has 80% concrete. If there are y pounds of this, then 0.80y pounds is pure concrete.
So far we have 0.95x+0.80y pounds of pure concrete from the two mixes
Divide this over 30 to get (0.95x+0.80y)/30
Setting this equal to 0.90 means we want the final mix to be 90% concrete.
Since we want 30 pounds total, we can say x+y = 30 which solves to y = 30-x. We'll use this later
-------------------------------
(0.95x+0.80y)/30 = 0.90
0.95x+0.80y = 30*0.90 .... multiply both sides by 30
0.95x+0.80y = 27
0.95x+0.80(30-x) = 27 ..... plug in y = 30-x
0.95x+0.80*30-0.80*x = 27
0.95x+24-0.80x = 27
0.15x+24 = 27
0.15x = 27-24 ..... subtracting 24 from both sides
0.15x = 3
x = 3/0.15 ........... dividing both sides by 0.15
x = 20
y = 30-x
y = 30-20
y = 10
