105 is 42% of what
number?
Answer:
250
Step-by-step explanation:
you have to do [tex]\frac{42}{100}[/tex] x ×=105the multiply both sides by 100 and dividing both sides by 42
so you will get
x=105 ×[tex]\frac{100}{42}[/tex] and that's how you will get your answer
or you can do
105 × 100 ÷ 42 on a calculator and you will get the same answer
The number 105 is 42 percent of the number 250.
let the unknown number be x.
To find the number that corresponds to 105 being 42% of it, we can set up the equation:
105 = 0.42x
To solve for x, we divide both sides of the equation by 0.42:
105 / 0.42 = x
x ≈ 250
Therefore, 105 is 42% of approximately 250.

How many groups of 3/4 are in each of the following quantities? 11/4, 6 1/2
There are complete 3 groups of 3/4 in 11/4.
There are complete 8 groups of 3/4 in 6 1/2.
To find the number of groups of 3/4 in 11/4, we divide it by 3/4.
[tex]\frac{\left(\frac{11}{4}\right)}{\left(\frac{3}{4}\right)}=3.67[/tex]
So there are complete 3 groups of 3/4 in 11/4.
To find the number of groups of 3/4 in 6 1/2, we divide it by 3/4.
[tex]\frac{\left(6\frac{1}{2}\right)}{\left(\frac{3}{4}\right)}=\frac{\left(\frac{13}{2}\right)}{\left(\frac{3}{4}\right)}=8.67[/tex]
So there are complete 8 groups of 3/4 in 6 1/2.

The first step is to graph the line 2x + y = -8. To do this, we can graph the x and y-intercepts. Letting x = 0, we get y = -8, so the y-intercept is -8. Letting y = 0, we get 2x = -8, so x = -4.
Graph the line between the points (-4, 0) and (0, -8). The line should be dotted, because this is a strict inequality (the points on the line are not part of the solution).
The next step is to substitute a point - I like to use (0,0): when x and y are equal to zero, we have 2(0)+0>-8, which is true. Therefore, the right side of the graph (which contains the point (0,0)) should be shaded. Note: If the inequality was not true, you would want to shade the opposite side of the graph.

A party size bag of Takis cost $5.95. If it's 30% off, but has a sales tax of 7%, what is the final cost?
Answer:
The bag of Takis now costs $4.46.
Step-by-step explanation:
We are given that a bag of Takis costs $5.95. We are also told that a markdown of 30% is applied to the product.
[tex]\displaystyle 100\%-30\% = 70\%\\\\\frac{70}{100}=0.7\\\\5.95 \times 0.7 = 4.165 \approx \$4.17[/tex]
Our new price is equal to $4.17, but we are told that a sales tax of 7% is also applied to the Takis. Therefore:
[tex]\displaystyle 100\% + 7\% = 107\%\\\\\frac{107}{100} = 1.07\\\\4.17 \times 1.07 = 4.4619 \approx \$4.46[/tex]
Therefore, the item with a markdown and sales tax applied is approximately $4.46.

Is the percent increase from 50 to 70 equal to the percent
decrease from 70 to 50? Explain.
Answer:
No.
Summary reason:
While the positive difference is the same, the original number is not. You are comparing the following ratios 20/50 and 20/70 respectively. As we can see, these are different numbers so they represent different percentages.
Step-by-step explanation:
The question is asking is the the positive difference over the original the same in each one. While the positive difference is 20 in both, the original is different. This makes the percent changes different as 20/50 does not equal 20/70.
That is, I'm just doing
(Biggest-Smallest)/original .
So the first one we have increase of
(70-50)/50=20/50=2/5=.4=40%
So the second one we have a decrease of
(70-50)/70=20/70=2/7=approximately 28.6%.
As you can clearly see these percentages are not equal.
Answer:
Sample response: No. The amounts of change are the same, but the original amounts are different. The ratio for the percent increase from 50 to 70 is 20/50, or 40%. The ratio for the percent decrease from 70 to 50 is 20/70, or about 29%.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
The number of small boxes in the right side of the equation = 10 boxes of 1
So , the value of A = 10
The number of small boxes in left side of the equation = 4 boxes of 1
The number of x in the equation = 3x
So , the equation is
3x + 4 = 10 be equation (1)
On simplifying the equation , we get
Subtracting 4 on both sides of the equation , we get
3x = 6
Divide by 3 on both sides of the equation , we get
x = 6/3
x = 2
Hence , the value of the equation is x = 2

which equation describes the line that passes through the point (-4,-8) and is parallel to the line represented by the equation 7x - 2y = 8
Answer:
The equation is;
2y = 7x + 12
Step-by-step explanation:
General equation form is ;
y = mx + b
where m is slope and b is y-intercept
Let us rewrite the first equation;
2y = 7x - 8
y = 7x/2 - 4
the slope here is 7/2
If two lines are parallel, their slopes are equal
so we use the point-slope form to get the second equation
y-y1 = m(x-x1)
(x1,y1) = (-4,-8)
Thus, we have
y + 8 = 7/2(x + 4)
2y + 16 = 7x + 28
2y = 7x + 12

Riley rakes 1/6 of a lawn in 2/3 hour. How many lawns can Riley rake per hour?
During the summer, Jody earns $10 per hour babysitting and $15 per hour doing yardwork. This week she worked 34 hours and earned $410. If x represents the number hours she babysat and y represents the number of hours she did yardwork, which system of equations models this situation?
A.
x + y = 34
10x + 15y = 410
B.
x + y = 410
10x + 15y = 34
C.
x + y = 34
15x + 10y = 410
D.
x + y = 410
15x + 10y = 34
Answer:
C! i’m sure off i hope i’m right
Step-by-step explanation:
Answer:
A. x+y=34
10x+15y=410
Step-by-step explanation:
First the question states that babysitting is represented by x and yard work is represented by y, so that eliminates C and D.
If x and y are the amount of hours put into babysitting and yard work you would make the equation, x+y=34 to find out how many hours of each were worked.
Then you would make the equation 10x+15y=410 with the known variables.
So in conclusion A is the correct answer.
