Answer:
$3.05 i'm pretty sure
Step-by-step explanation:
If one pound is $0.94 and she bought 3.25 pounds you multiply 3 by 0.94 and get $2.82 (we multiply by 3 to make it easier and to deal with the .25 later) then now we deal with the .25, since .25 is 1/4 in fraction just find out what 1/4 of .94 is which is .23 cents. So add $2.82 and $0.23 and you get $3.05
There are 5.2 x 10^5 words in the English dictionary. What is the average number of words recorded under each of the 26 letters? Give your answer in scientific notation.
Answer:
2.0*10^4
Step-by-step explanation:
[tex]5.2 *10^5[/tex] words
26 categories
[tex]\frac{5.2 *10^5}{26} =\frac{520 000}{26} =20 000[/tex]
[tex]2.0*10^4[/tex]
so there is an average of 2.0*10^4 words per letter
Write a function g whose graph represents a reflection in the y-axis followed by a translation 3 units to the right of the graph of f(x)=|x|.
g(x)=
Answer:
[tex]g(x) = |x - 3|[/tex]
Step-by-step explanation:
Given
[tex]f(x) = |x|[/tex]
Required
Translate 3 units right
The result of a right translated function is:
[tex]g(x) = f(x - h)[/tex]
Where h is the unit of translation
[tex]h = 3[/tex]
[tex]g(x) = f(x - 3)[/tex]
Solve for f(x - 3)
[tex]f(x) = |x|[/tex]
[tex]f(x - 3) = |x - 3|[/tex]
Hence;
[tex]g(x) = |x - 3|[/tex]
write an equation in slope-intercept form for the line passing through each pair of points. (-4,-2) and (2,3)
Answer:
y = 5/6x +4/3
Step-by-step explanation:
The 2-point form of the equation for a line is a useful place to start.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (3 -(-2))/(2 -(-4))(x -(-4)) -2
y = 5/6(x +4) -2
y = 5/6x +20/6 -12/6
y = 5/6x +4/3
: Consider the distance from the school to the coffee shop and the
distance from the library to the coffee shop. Draw their respective
line segments in the above graph. If the school is relocated in a
way that it is collinear to the coffee shop and the library, and the
distance to the coffee shop is preserved, then the point
representing the school will partition the line segment from the
coffee shop to the library in a x: y ratio. What are the values of x
and y?
Answer:
x = 7 and y = 1
Step-by-step explanation:
Coordinates of Coffee shop = (12, 16)
Coordinates of Library = (16, 8)
School has been shifted to the new position so that distance of school is preserved from the coffee shop.
Coordinates of the new position of school = (15, 10)
Ratio in which distance between coffee shop and library is divided by the location of school is x : y.
If a segment having extreme ends [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is divided into two parts by point (x, y) in the ratio of m : n,
x = [tex]\frac{mx_2+nx_1}{m+n}[/tex]
y = [tex]\frac{my_2+ny_1}{m+n}[/tex]
From the points given in the picture,
15 = [tex]\frac{16x+8y}{x+y}[/tex]
15x + 15y = 16x + 8y
15y - 8y = 16x - 15x
7y = x
[tex]\frac{x}{y}=\frac{7}{1}[/tex]
Therefore, x = 7 and y = 1 will be the answer.

How many solutions does this equation have? 3s − 8 = 2s
3s - 8 = 2s
First, let's subtract 3s from both sides
-8 = -s
Divide both sides by -1
8 = s
You have one solution which is s = 8
There is only a solution for the given equation 3s − 8 = 2s, s=8.
What is the equation?A mathematical equation is a claim that two expressions, which may contain variables or numbers, are equal. Equations are essential questions, and the main motivations for the development of mathematics have been efforts to methodically find answers to these questions.
It is given that the equation is,3s − 8 = 2s.
In order to find the value of s we have to simplify the given equations by applying the arithmetic operations.
3s - 8 = 2s
3s-2s= +8
s=8
Thus, the number of the solution for the given equation will be 1.

If you mix red and white paint in different ratios, you will get different shades of pink paint. If the ratios are equivalent, the shades of pink will be the same. ◦ Mai mixed a batch of pink paint using 5 cups of red paint and 3 cups of white paint. ◦ Priya mixed another batch of pink paint using 7 cups of red paint and 4 cups of white paint. Are these two batches the same shade of pink? Explain.
Answer:
No,
Step-by-step explanation:
be a light pink and one would be a darker shade of pink.because
The given two batches doesn't have the same shade of pink because the proportion of 7 cups of red : 4 cups of white is greater than 5 cups of red : 3 cups of white.
What is proportion?A proportion is an equation in which two ratios are set equal to each other. In simple words, equivalent fraction are called as proportions.
Now it is given that,
Mai's pink contains- 5 cups of red paint and 3 cups of white paint
So, Ratio of red : white = 5 : 3
⇒ 5/3 = 1.67
Priya;s pink contains- 7 cups of red paint and 4 cups of white paint
So, Ratio of red : white = 7 : 4
⇒ 7/4 = 1.75
Thus, the proportion of 7 : 4 > 5 : 3
Thus, the given two batches doesn't have the same shade of pink because the proportion of 7 cups of red : 4 cups of white is greater than 5 cups of red : 3 cups of white.

The length of a rectangle is 4 units shorter that half the with .if the length of the rectangle is 18 units,which equation can be used to find w , the width of rectangle
Hey there! I'm happy to help!
Let's call our length and width L and W respectively.
L=1/2W-4
L=18
Since L is equal to 18, we can just replace the L in the first equation with 18 and solve.
1/2W-4=18.
We add 4 to both sides.
1/2W=22
We divide both sides by 1/2.
W=44

find the 10th term f(1) = 30 ; f(n) = 2 * f(n-1) -50
Answer: :F(x)=x^2+x-6
The 10th term of the given sequence is -10190.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given function is f(1)=30; f(n)=2×f(n-1)-50.
Here,
When n=2
f(2)=2×f(2-1)-50
=2×f(1)-50
= 2×30-50
= 10
When n=3
f(3)=2×f(3-1)-50
=2×f(2)-50
= 2×10-50
= -30
When n=4
f(4)=2×f(4-1)-50
=2×f(3)-50
= 2×(-30)-50
= -60-50
= -110
When n=5
f(4)=2×f(5-1)-50
=2×f(4)-50
= 2×(-110)-50
= -220-50
= -270
When n=6
f(4)=2×f(6-1)-50
=2×f(5)-50
= 2×(-270)-50
= -540-50
= -590
When n=7
f(4)=2×f(7-1)-50
=2×f(6)-50
= 2×(-590)-50
= -1180-50
= -1230
When n=8
f(4)=2×f(8-1)-50

= 2×(-1230)-50
= -2510
When n=9
f(4)=2×f(9-1)-50

Answer:
Pencil: $0.60 Rubber: $0.48
Step-by-step explanation:
Let the cost of a pencil be p and the cost of a rubber be r.
[tex]p+r=1.08[/tex] (Equation 1)
[tex]4p=5r[/tex] (Equation 2)
Divide both sides by 4:
[tex]p=\frac{5}{4} r[/tex]
Substitute this into Equation 1:
[tex]\frac{5}{4} r+r=1.08[/tex]
Multiply both sides by 4:
[tex]\frac{5}{4}r* \:4+r* \:4=1.08*4[/tex]
[tex]5r+4r=4.32[/tex]
[tex]9r=4.32[/tex]
Divide both sides by 9:
[tex]\frac{9r}{9}=\frac{4.32}{9}[/tex]
[tex]r=0.48[/tex]
Since r + p = 1.08,
[tex]p=1.08=0.48=0.60[/tex]
