if 9 out of 25 people are left-handed what percent are right-handed
Answer:
64%
Step-by-step explanation:
If 9 out of 25 people are left-handed
That means 25-9 = 16 people are right handed
or 16/25 are right handed
Multiply the top and bottom by 4 to get it out of 100
64/100
Percent means out of 100
64% are right handed

Mrs. Barkley is making a snack mix out of different flavors of pretzels and chips. The weight of each snack package she used to make the mix is shown on the line plot below. What is the total weight, in ounces, of the snack mix?
Answer:
20 ounces
Step-by-step explanation:
The line plot is attached below.
From the line plot, we can see that there is a total of 7 snack mix. Two of the snack mix weigh 1 and half (1.5) ounces each, one snack measure 2 and three quarter (2.75) ounce, three snack mix measure three and half (3.5) ounce each and one snack measure 3 and three quarter (3.75) ounce. Therefore the total weight of the snack mix is:
Total weight = (2 * 1.5) + (1 * 2.75) + (3 * 3.5) + (1 * 3.75)
Total weight = 20 ounces

what’s the equation for this table?
Answer:
y=2.5x-3
Step-by-step explanation:
first, we find the y-intercept, which is the number with a zero in the x
That would be -3
next, we find the slope
to do this, we have to take two numbers on the y side next to each other and subtract.
For this example we will use 7 and 2
7-2=5
And just to be positive, we will also do 12 and 7
12-7=5
Okay, now that we know that the number is growing by 5 every time, we know that it is now 5/2 because y is growing by 5 and x is growing by 2
Now, we make the x side grow by only 1, so to do this, we will divide both sides by two.
Now we have 5/1 or just 5
Finally, to put that into the right format, we do y=5x-3
You're Welcome
Good Luck

Qual o raio de uma superfície esférica com 40 cm2 de área, em cm, aproximada às centésimas? Responde à seguinte questão, escrevendo apenas o valor numérico em algarismos
Responder:
1,78 cm
Explicación paso a paso:
El área de superficie total de la superficie esférica se expresa como;
T = 4πr² donde
r es el radio
Dado
TSA = 40 cm²
Sustituir
40 = 4πr²
r² = 40 / 4π
r² = 10 / π
r² = 10 / 3,14
r² = 3,185
r = √3,185
r = 1,78
por lo tanto, el radio de la esfera a la centésima más cercana es 1,78 cm

You deposit 600$ in a savings account.the account earns 10% simple interest per year
A. What is the interest after 10 years?
B.what is the balance after 10 years
Answer:
A) $600
B) $1200
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 10%/100 = 0.1 per year,
then, solving our equation
I = 600 × 0.1 × 10 = 600
I = $ 600.00
The simple interest accumulated
on a principal of $ 600.00
at a rate of 10% per year
for 10 years is $ 600.00.

[tex] (x + 8)(x - 5) [/tex]
Answer: [tex]\huge\boxed{\ x^2+3x-40}[/tex]
My step-by-step explanation:
1. First thing we do is: Distribute
(x+8)(x−5)x
(x−5)+8(x−5)
2. Second thing:Distribute
x(x−5)+8(x−5)
x^2−5x+8(x−5)
3.Third thing: Distribute
x^2−5x+8(x−5)
x^2−5x+8x−40
4. Fourth thing: Combine like terms
x^2−5x+8x−40

HELP ME JIM! Math HW
Problem 7
Answers:
dots A = 2dots B = 5-----------------------
Explanation:
In step 1, there are 2 dots. So that number (2) fills in the blank for dots A.
Step 2 has 5 dots, which fills in the blank for dots B.
===========================================================
Problem 8
Answer: A) Quadratic
-----------------------
Explanation:
We have this sequence of dots: {1, 2, 5, 10, ...}
Note the increments of +1, +3, +5, ...
The increments aren't the same, so we don't have a linear sequence. But because the increment amounts go up by 2 each time, this strongly implies a quadratic sequence.
The rule for this sequence is n^2 + 1. Whatever the step number (n) is, we square it and add 1 onto that result. For instance, for step 3, we have n = 3 that leads to n^2 + 1 = 3^2 + 1 = 9 + 1 = 10. Also, note how the lone dot on the left of step 3 is tacked onto the 3 by 3 square of dots.
===========================================================
Problem 9
Answers:
dots A = 3dots B = 9-----------------------
Explanation:
Same idea as problem 7
===========================================================
Problem 10
Answer: B) Exponential
-----------------------
Explanation:
The sequence is {1, 3, 9, 27, ...}
In step 3 we have 3 rows and 9 columns of dots to give 3*9 = 27 dots total here.
The sequence is growing by a factor of 3 each time. In other words, we are tripling the terms or multiplying each term by 3 to get the next term.
Therefore, we have an exponential pattern.
The rule is 3^n
Eg: if we're on step n = 2, then we have 3^n = 3^2 = 9 dots.
*5 EXTRA POINTS* The height of a cylinder is 8 units. The circumference of the base of the cylinder is 10π units.
Which measurement is closest to the volume of the cylinder in cubic units?
the answer would be 80 cubuc unitsStep-by-step explanation:
Answer:
628.32
Step-by-step explanation:
the circumference is ALWAYS Pi times more than the diameter so the diameter must be 10, and 10/2 is 5 so the radius is 5
5 squared is 25
25 times π is 78.5398163397
and 78.5398163397 times 8 is around 628.32
