The number of girls who work at Super shopper is 2 more than 3 times the number of boys. If 30 boys work at super shopper; how many girls work there?
***Please Help Me***
The number of girls who work there are:
92
Step-by-step explanation:It is given that:
The number of girls who work at Super shopper is 2 more than 3 times the number of boys.
This means that:
If the number of boys= x
Then the number of girls= 3x+2
If 30 boys work at super shopper.
i.e. x=30
Then 3x+2=92
Hence, the number of girls who work there are: 92
1. Direct variation
A. Write an equation for the following statements.
B. Write an equation when y varies directly as x.
1. y=63 when x=9
2. y=121 when x=11
3. y=36 when x=4
4. y=224 when x=8
(1) y = 7x , (2) y = 11x , (3) y = 9x , (4) y = 28x
given y varies directly as x then y = kx ( k is the constant of variation )
(1) find k using the given conditions k = [tex]\frac{y}{x}[/tex] = [tex]\frac{63}{9}[/tex] = 7
equation is y = 7x
(2) k = [tex]\frac{121}{11}[/tex] = 11
equation is y = 11x
(3) k = [tex]\frac{36}{4}[/tex] = 9
equation is y = 9x
(4) k = [tex]\frac{224}{8}[/tex] = 28
equation is y = 28x

This is because both lines meet at this direct point on the graph.
Answer:
Yes, the lines will intersect because the slopes are different. Also, both lines have a y-intercept of -7, so they both include the point (0, –7).
Step-by-step explanation:
Solve for x. -3x = -15 x = -5 x = 5 x = -45
-3x = -15 divide both sides by (-3)
-3x:(-3)=-15:(-3)
x = 5
Answer:
The answer is b, 5
Step-by-step explanation:
-3x = -15
(it sometimes helps to flip it, so that's what I'm going to do here to help it to make more sense)
x(-3) = -15
x(-3) devided by (-3) = -15 devided by (-3)
when you devide a negitive by a negative the answer will be positive
the absolute value of 15 devided by three is 5
your answer is a positive five, or just 5

Brittany says that to determine the distance between 180 and 34, you can just subtract 180 - 34.
Is it true in this case? Why or why not?
It is true in this case, because you are trying to find the distance between two points. That also means you are trying to find the difference between two points, and to find the difference, you subtract. That is why what Brittany says is true.
Absolute value is always positive because absolute value represent distance and distance can not be negative.
Yes it is true, To determine the distance between 180 and 34, you can just subtract 180 - 34.
Since, absolute value is represent distance between two points
and absolute value is always greater or equal to zero.
Now, To determine the distance between 180 and 34, just subtract 180 - 34.
and then take absolute value.

The graph of a linear function is shown which word describes the slope of the line the choices and graph is below
negative
ExplanationLet's find the slope of our line using the slope formula:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
where
[tex]m[/tex] is the slope of the line
[tex](x_{1},y_{1})[/tex] are the coordinates of the first point on the line
[tex](x_{2},y_{2})[/tex] are the coordinates of the second point
From the graph we can get the points (-2, 1) and (2, -1), so [tex]x_{1}=-2[/tex], [tex]y_{1}=1[/tex], [tex]x_{2}=2[/tex], and [tex]y_{2}=-1[/tex]. Let's replace the values in our formula to find [tex]m[/tex]:
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m=\frac{-1-1}{2-(-2)}[/tex]
[tex]m=\frac{-2}{2+2}[/tex]
[tex]m=\frac{-2}{4}[/tex]
[tex]m=-\frac{2}{4}[/tex]
[tex]m=-\frac{1}{2}[/tex]
The slope of the graph of the linear function is [tex]-\frac{1}{2}[/tex]; since [tex]-\frac{1}{2}[/tex] is a negative number, the slope of the graph is negative.

jack popped some popcorn, but 3 of the 150 did not pop. Determine whether or not each popcorn snack below has the same ratio of unpopped to total kernals as Jack's popcorn
Answer:
b and c
Step-by-step explanation:
Jack popped some popcorn, but 3 of the 150 did not pop.
the ratio of the jack's popcorn = [tex]\frac{3}{150}[/tex]
= [tex]\frac{1}{50}[/tex]
= 1 : 50
We will go through all the other given ratio to find whether they are same ratio of Jack's or not.
a. 2 unpopped out of 75 kernels = [tex]\frac{2}{75}[/tex]
= 2 : 75 This is not a match
b. 2 unpopped out of 200 kernels = [tex]\frac{4}{200}[/tex]
= [tex]\frac{1}{50}[/tex]
= 1 : 50 This is same
c. 1 unpopped out of 50 kernels = [tex]\frac{1}{50}[/tex]
= 1 : 50 This is also same
So b and c has the same ratio of unpopped to total kernels as Jack's popcorn.
A goat is tethered (tied up) to a stake in the ground with a 5 m rope. The goat can graze to the full length of the rope a full 360 degrees around the stake. How much area does the goat have in which to graze?
The answer to your question is
d.
78.5 m^2
78.54 m² is your answer. So to recap, a goat tethered to a stake in the ground with a 5 m rope has 78.54 meters to graze.
We get this answer by putting the information into an equation. We know that a circle has 360° (360 degrees) and so when we see the problem say that the goat can graze 360 degrees around the stake, we instantly know it's talking about a circle. Look at the question, it's asking about the area of the circle. Now we can make an equation to find the area of this circle.
The area of a circle is A = πr²
That's Area = Pi times Radius squared.
We'll use 3.14 as substitute for Pi. The radius was given to us, it is 5 m. Put the information into the formula.
A = 3.14 * 5²
Now we do the order of operations. In the order of operations, we have no parenthesis to work with, but we do have an exponent. So we take 5 to the second power, (5² = 5 * 5) and we update our problem.
A = 3.14 * 25
Now we finish the problem by multiplying 3.14 and 25.
A = 78.54
We're not entirely done. Now we include our units of measurement. In this case, we were using m for meters. When solving for area, the unit is always squared in the final answered. So this would be our final answer:
A = 78.54 m²

According to the Complex Conjugate Root Theorem, if a+bi is a root of a quadratic equation, then __blank__ is also a root of the equation. Which expression correctly completes the previous sentence?
a−bi
a+bi
−a−bi
−a+bi
Answer:
a-bi
Step-by-step explanation:
If a quadratic equation lx^2+mx+n=0 has one imaginary root as a+bi then the other root is the conjugate of a+bi = a-bi
Because we have l, m and n are real numbers and they are the coefficients.
Sum of roots = a+bi + second root = -m/l
When -m/l is real because the ratio of two real numbers, left side also has to be real.
Since bi is one imaginary term already there other root should have -bi in it so that the sum becomes real.
i.e. other root will be of the form c-bi for some real c.
Now product of roots = (a+bi)(c-bi) = n/l
Since right side is real, left side also must be real.
i.e.imaginary part =0
bi(a-c) =0
Or a =c
i.e. other root c-bi = a-bi
Hence proved.
The angles in a triangle are such that one angle is 78 degrees more than the smallest angle, while the third angle is 4 times as large as the smallest angle. Find the measures of all three angles.
Let the angles are x, y and z.
Let the smallest angle is x
one angle is 78 degrees more than the smallest angle.⇒ y = x + 78 → (1)
the third angle is 4 times as large as the smallest angle. ⇒ z = 4 x → (2)
we should know that the sum of the angles of the triangle = 180°
∴ x + y + z = 180 →(3)
substitute from (1) and (2) at (3)
∴ x + ( x +78) + (4x) = 180
∴ 6x = 180 - 78 = 102
∴ x = 102 ÷ 6 = 17°
∴ y = 17 + 78 = 95°
∴ z = 4x = 68°
So, the measures of all three angles are 17°, 95° and 68°
12 r - 18 = 13 r + 18
The solution of expresison is, r = - 38

An expression to simplify,
12r - 18 = 13r + 18
Now, We can simplify the expression as,
12r - 18 = 13r + 18
Subtract 12r on both sides,
12r - 18 - 12r = 13r - 12r + 18
- 18 = r + 18
Subtract 18 on both sides,
- 18 - 18 = r
r = - 36
Therefore, The solution is, r = - 36

The length of a postage stamp is 4 1/4 millimeters longer than its width. The perimeter of the stamp is 124 1/2 millimeters. Write the equation that represents the situation. What is the width of the postage stamp? What is the length of the postage stamp?
Answer:
- The equation is: [tex]\frac{249}{2}=2(x+\frac{17}{4})+2x[/tex]
- The width of the postage stamp is 29 milimeters.
- The length is 33.25 milimeters.
Step-by-step explanation:
1. The length ([tex]y[/tex]) is [tex]4^{\frac{1}{4} }mm=\frac{17}{4}mm[/tex] longer than the width ([tex]x[/tex]):
[tex]y=x+\frac{17}{4}[/tex]
2. The perimeter is [tex]124^{\frac{1}{2}}mm=\frac{249}{2}mm[/tex].
3. The perimeter of a rectangle is:
[tex]Perimeter=2Length+2Width[/tex]
4. Substitute values:
[tex]\frac{249}{2}=2(x+\frac{17}{4})+2x[/tex]
5. Solve for the width [tex]x[/tex]:
[tex]\frac{249}{2}=2x+\frac{34}{4}+2x\\x=\frac{116}{4}\\x=29[/tex]
6. Calculate the length:
[tex]y=x+\frac{17}{4}\\y=29+\frac{17}{4}\\y=33.25[/tex]
The width and length of the postage stamp are calculated by formulating and solving an equation based on the given perimeter and the relationship between the length and width. The width is found to be 29 mm, and the length is 33.25 mm.
Explanation:The subject of this question is Mathematics and it's related to the concept of the perimeter of a rectangle. If we denote the width of the postage stamp as 'W' (in millimeters), then it's length will be 'W + 4.25' millimeters because it's stated in the problem that the length is 4.25 mm longer than the width.
The perimeter of a rectangle (which is the shape we can assume for a postage stamp) is calculated as follows: Perimeter = 2(Length + Width). Substituting the value for length that we've assigned, we get this equation:
124.5 = 2[(W + 4.25) + W]
Solving this equation step-by-step will lead you to the answer. First, distribute the 2 into the parentheses which gives: 124.5 = 2W + 8.5 + 2W. Combine like terms to simplify: 124.5 = 4W + 8.5. Then, subtract 8.5 from both sides of the equation: 116 = 4W. Lastly, divide by 4 to find 'W': W = 29 mm. Therefore, the width of the postage stamp is 29 mm, and the length is 29 mm + 4.25 mm = 33.25 mm.

Mary owned n sheep and Sam had exactly 4 times as many sheep as Mary. Mary buys 17 extra sheep and Sam sells 8 of his sheep. Sam still has more sheep than Mary. Form an inequality, in terms of n. Solve the inequality to find the least value of n. You must show all your working.
Answer:
The least value of n is, 9.
Step-by-step explanation:
Let n be the number of sheep in Integer.
Mary(M) owned the number of sheep is n i.e, M = n sheep
Sam(S) had exactly four times as many sheep as Mary , i.e, S = 4 n sheep
As per the given condition Mary buys 17 extra sheep
Now, Mary has total number of sheep, M = n +17 sheep
And Sam sells 8 of his sheep that means he has now,
[tex]S = 4n -8[/tex]
But, Sam still has more sheep than Mary i.e, [tex]4n-8 > n+17[/tex]
Solve an inequality: [tex]4n-8 > n+17[/tex]
Add 8 both sides we get;
[tex]4n-8+8>n+17+8[/tex]
Simplify:
[tex]4n>n+25[/tex]
Now, subtract n from both the side, we get;
[tex]4n -n>n+25-n[/tex]
Simplify:
[tex]3n>25[/tex] or [tex]n>\frac{25}{3}=8.33333333[/tex]
Since n is the number of sheep in integer,
then the least value of n is, 9.
