Jacob checked two bags of potato chips for broken chips. The first bag
had 6 broken chips, which was 10% of the chips in bag 1. The second bag
had 12 broken chips, which was 25% of the chips in bag 2. How many
total chips were in both bags?
Answers
Answer:
3
Step-by-step explanation:
Total 108 chips were in the both bags.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
10% of chips in the first bag is 6.
To find the total chips in the first bag:
6 = 10 x total number of chips in the first bag / 100
total number of chips in the first bag = 600/10
total number of chips in the first bag = 60
25% of chips in the second bag is 12.
To find the total chips in the second bag:
12 = 25x total number of chips in the second bag / 100
total number of chips in the second bag = 1200/25
total number of chips in the second bag = 48
Now, total chips in the both bags = 60 + 48 = 108
Therefore, total 108 chips were in the both bags.

Answers
Answer:
[tex]\boxed{-\frac{7}{12} }[/tex]
Step-by-step explanation:
[tex]-1\frac{1}{3} +\frac{3}{4}[/tex]
→ Make both denominators the same
[tex]-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}[/tex]
→ Convert mixed number into improper fraction
[tex]-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}=-\frac{16}{12} +\frac{9}{12}[/tex]

[tex]-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}=-\frac{16}{12} +\frac{9}{12}=-\frac{7}{12}[/tex]
The required simplification o f[tex]-1\frac{1}{3} +\frac{3}{4}[/tex] into fraction form is -1 / 12
To simplify -1 1 / 3 plus 3 / 4 into fraction form.
The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.
What is the fraction?Fraction is defined as the number of compositions constituting the Whole. And it is represented as a / b, where a = numerator and b = denominator.
Since the given problem is
[tex]-1\frac{1}{3} +\frac{3}{4}[/tex]
We need to simplified it into fraction form like a / b.
[tex]=-1\frac{1}{3}+\frac{3}{4} \\= -2/3 + 3/4[/tex]
= ( -8 + 9 ) / 12
= -1 / 12
Thus, The required simplification of [tex]-1\frac{1}{3} +\frac{3}{4}[/tex] into fraction form is -1 / 12.

The formula s=12at ^2 is used to calculate the distance s travelled by a bike when a=3 and t=10, each correct to the nearest integer, calculate the lower bound of the distance s
Answers
Answer:
Step-by-step explanation:
Given the formula for calculating the distance travelled expressed as;
s=1/2at^2
Given
a = 3
t = 10
Required
lower bound of s
Substitute the given values into the equation;
s=1/2at^2
S = 1/2(3)(10)^2
S = 1/2 * 3 * 100
S = 3 * 50
S = 150
Hence the lower bound of distance S is 150
Every week, Hector works 20 hours and earns $210.00. He earns a constant amount of money per hour.
Part A
Write an equation that can be used to determine the number of hours, h, Hector works given the number of weeks, W.
Enter your equation in the space provided
Part B
Write an equation that can be used to determine Hector's earnings, in dollars, m, for h hours of work.
Enter your equation in the space provided.
Answers
Answer:
A). h = 20 w
B). m = 10.5h
Step-by-step explanation:
Part (A).
Let the total number of hours Hector worked = h
And total number of weeks worked by Hector = w
Therefore, number of hours Hector worked in a week = [tex]\frac{h}{w}[/tex]
Since, total number of hours worked in a week = 20
Equation will be,
20 = [tex]\frac{h}{w}[/tex]
h = 20w
Part (B).
Per hour earning of Hector = [tex]\frac{\text{Total earning}}{\text{Number of hours worked}}=\frac{210}{20}[/tex]
[tex]\frac{m}{h}=10.5[/tex]
m = 10.5h

Step-by-step explanation:
-5(3x -7) + 11 = 1
Distribute 5:
-15x + 35 + 11 = 1
Combine like terms:
-15x + 46 = 1
Subtract by 46 =
-15x = 1 - 46
-15x = -45
Divide by -15:
x = -45 / -15
x = 3
Answer:
x=3
Step-by-step explanation:
Use the distributive property to multiply −5 by 3x−7.
−5(3x−7)+11=1
Add 35 and 11 to get 46.
−15x+35+11=1
Subtract 46 from both sides.
−15x+46=1
Subtract 46 from 1 to get −45.
−15x=1−46
Divide both sides by −15 and you get x=3.

33 managers and 27 non-managers attended a company meeting. What percentage of the people in the meeting were managers?
Answers
Answer:
81.82%
Step-by-step explanation:
Step 1: We make the assumption that 33 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=33$100%=33.
Step 4: In the same vein, $x\%=27$x%=27.
Step 5: This gives us a pair of simple equations:
$100\%=33(1)$100%=33(1).
$x\%=27(2)$x%=27(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{33}{27}$100%x%=3327
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{27}{33}$x%100%=2733
$\Rightarrow x=81.82\%$⇒x=81.82%
Therefore, $27$27 is $81.82\%$81.82% of $33$33.
Sarah is a computer engineer and manager and works for a software company. She receives a fixed annual increase in the number of projects she handles each year. She worked on 129 projects in the fourth year of her employment and 207 projects in her tenth year
Answers
Answer: See explanation
Step-by-step explanation:
You didn't say what you'll like to calculate but let me help out.
Fourth year = 129 project.
Tenth year = 207 projects
We can form this into an arithmetic progression
Tn = a + (n-1)d
4th year = a + 3d = 129 ........ i
10th year = a + 9d = 207 ....... ii
Subtract equation i from equation ii
6d = 78
d = 78/6 = 13
This means that 13 new projects are added every year
For the first year, the number of projects done was:.
a + 3d = 129
a + 3(13) = 129
a + 39 = 129
a = 129 - 39 = 90
She worked on 90 projects in the first year.
