Blake works at a grocery store and is paid every two weeks. He earned $486.50 this week. His pay will increase by 10% next week. What will his total
pay be for the two week period?
Answer:
$1,021.60
Explanation:Blake earn $486.50 in 1 week.
"The next week, his pay will increase by 10%"
2 weeks:
= $486.50 * 1.10(+10%)
= $535.15
Blake paid after two weeks. He got

What is an linear equation ?A linear equation has the algebraic form y=mx+b, where m is the slope and b is the y-intercept, and consists of a first-order (linear) term and a constant. When x and y are the variables, the aforementioned is sometimes referred to as a "linear equation of two variables."
Each line in the Euclidean plane is conceived of as a collection of all the answers to a linear equation with two variables. Lines represent the solutions of linear equations in the Euclidean plane. This is where the word "linear," which is used to characterize this class of equations, originates.

do 11, 9 ,17 make a triangle
We use the followig property of triangles:
• One side cannot be equal or greater than the sum of the other two sides
The sides of this triangle are: 11, 9 and 17.
The sum of the first two sides is: 11+9=20
The sum of the two sides is greater than the other remaining side (17).
Thus, 11, 9 and 17 do not make a triangle.
if f(x) has a remainder of -2 when divided by x-7, what is f(7)?
If f(x) has a remainder of -2 when divided by x-7, f(7) is -2.
The leftover is -2 when the function f(x) is divided by x-7, according to the question.
hence the result will be -2 if we use the value x = 7 in the function.
This has the same meaning as "f(7)" because "f(7)" also means to enter "x = 7" in the function and "-2" as the response.
Therefore, if f(x) is divided by x-7 with a remainder of 2, f(7) is equal to -2.

Which of the following equations is equivalent to 4x + 2y = 12? A. 2y = -4x + 12 B. y=-2x + 6 C. y = 2X - 6 D. y = 8x + 24
Let's find the equivalent equation to:
4x + 2y = 12
2y = 12 - 4x
Dividng by 2 at both sides:
2y/2 = 12/2 - 4x/2
y = 6 - 2x
We can see that choices B and C are not correct because the signs.
If we multiply by 2 at both sides, we have:
2y = 12 - 4x
We can see that if we change the order at the right side of the equation, we have:
2y = -4x + 12

Annie purchased a season pass for the new aquarium at a cost of $110. if she uses the pass 10 times this year , what is the unit rate in cost per visit?
If she uses the pass 10 times this year then the unit rate in cost per visit is $11 unit per visit.
In the given question,
Annie purchased a season pass for the new aquarium at a cost of $110.
If she uses the pass 10 times this year then we have to find the unit rate in cost per visit.
We have to find the unit rate.
Unit rate means finding the value of one object, that means we have to find the cost of one visit.
The cost of season pass is $110.
She visit aquarium 10 times.
We find the unit rate cost per visit by dividing the total cost of season pass for the new aquarium by total times she visits in the new aquarium.
10 times = $110 cost
Divide by 10 on both side
10/10 times = $110/10 cost
1 times = $11 cost
Hence, if she uses the pass 10 times this year then the unit rate in cost per visit is $11 unit per visit.

What is are of triangle?
The territory included by a triangle's sides is referred to as its area. Depending on the length of the sides and the internal angles, a triangle's area changes from one triangle to another. Square units like m2, cm2, and in2 are used to express the area of a triangle.
The sum of all angle of triangle = 180
Let x be the smalletst angle
2nd angle will be x+24
and 3rd angle will be 2x
So sum of all angles x+2x+x+24=180
4x=180-24
x=156/4
x=39

Last year the book fair sold 200 bookmarks compared to the 180 sold this year. What is the percent of change in the number of bookmarks sold?
Answer:
Step-by-step explanation:
1. Subtract 200 from 180
200 - 180 = 20
2. Divide the difference of the number of bookmarks by last years
20 / 200 = 0.1
3. Multiply 0.1 by 100 to get the percentage
0.1 x 100 = 10 %
4. Since this is a reduction in number of bookmarks sold, then it would be a -10% change in the number of bookmarks sold.

SOLUTION
Let's look at the graphical solution of the pair of simultaneous equations
From the graph, we can see that the equations have at least one solution, which are 2.556, and -0.333. Hence, it is said to be consistent.
Now, since the solutions intersect only at one place, it means that it has exactly one solution. If a consistent equation has exactly one solution, it is said to be independent.
Therefore, the systems of equations are consistent and independent

What is the equation for the line in slope-intercept form?
Answer:
y = -2x - 4
Step-by-step explanation:
Slope intercept form : y = mx + b
Where
m = slopeb = y intercept Finding Y - InterceptThe y intercept is the point where the line crosses the y axis.
Here, just by looking at the graph we can say that the y intercept is at (0,-4) because that is where the line passes the y intercept.
This means that b = - 4
Finding the slopeWe can find the slope using the following formula
Slope = (y2-y1)/(x2-x1)
Where, (x1,y1) and (x2,y2) are any given points on the line
The points used can vary however I have chosen (0,-4) and (-2,0)
Defining our variables we get (x1,y1) = (0,-4) and (x2,y2) = (-2,0)
So we have x1 = 0 , x2 = -2 , y1 = -4 and y2 = 0
We now plug this in to the formula
Slope = (y2-y1)/(x2-x1)
==> plug in x1 = 0 , x2 = -2 , y1 = -4 and y2 = 0
Slope = (0-(-4))/(-2-0)
==> remove parenthesis
Slope = (0+4)/(-2-0)
==> simplify addition and subtraction
Slope = 4/-2
==> simplify fraction
Slope = -2
So the slope or "m" is -2
Plugging the y intercept and slope into y intercept formAgain we have y = mx + b
m = slope so m = -2 and b = y intercept so b = -4
Plugging this in, we acquire y = -2x - 4

Answer:
The length of the playground = 11 yards
The width of the playground = 14 yards
Explanation:
Let the length of the playground = l yd.
The width of the playground is 3 yd longer than its length.
Therefore, the width of the playground = (l+3) yd
Area of a Rectangle = Length x Width
Substituting the given values, we have:
[tex]154=l(l+3)[/tex]We then solve the equation above for l.
[tex]l^2+3l-154=0[/tex]We factorize:
[tex]\begin{gathered} l^2+14l-11l-154=0 \\ l(l+14)-11(l+14)=0 \\ (l-11)(l+14)=0 \\ l-11=0\text{ or l+14=0} \\ l=11\text{ yards, }l\neq-14 \end{gathered}[/tex]The length of the playground = 11 yards

The amount of each deposit is $210000
What is compound interest?Compound interest is when you reinvest your income. Compound interest distinctively means "interest on interest" and is the reason so many investors are so successful.
The computation of the each deposit is shown below:
Given that
Future value be $70,000
Time period = 10 × 2 = 20
And, the rate = 9% ÷ 2 = 4.5%
Now the formula is as follows
= (Future value × rate of interest) ÷ (1 + rate of interest)^time period - 1
= ($70,000 × 4.5) ÷ (1 + 0.025)²⁰⁻¹
= $315,000 ÷ 1.5
