Step-by-step explanation:
I guess, she is checking how FAR she runs each day (and not how fast ...).
how many more miles did she run on Friday ?
we get this by calculating the difference between the 2 values. that is what subtraction is for.
7 2/8 - 3 3/4
as long as we have the numbers as combination of full and fraction numbers, we can subtract the full numbers right away.
7 2/8 - 3 3/4 = 4 2/8 - 3/4
now we convert both numbers to full fractions :
4 2/8 - 3/4 = (32 + 2)/8 - 3/4 = 34/8 - 3/4
and then we bring both fractions to the same denominator, in this case 1/8 :
34/8 - 3/4 = 34/8 - 3/4×2/2 = 34/8 - 6/8 = 28/8
now we can simplify
28/8 = 7/2 = 3 1/2
so, she ran 3 1/2 miles more in Friday than on Tuesday.
FYI
I just wanted to show you the full formal flow of such a calculation.
but we could have gotten the result quicker by recognizing that we can simplify the numbers already at the beginning :
7 2/8 - 3 3/4 = 7 1/4 - 3 3/4 = 4 1/4 - 3/4 = 3 2/4 = 3 1/2

Answer:
158 m²
Step-by-step explanation:
Get the area of all the faces, then add them
2(8 x 3) = 48
2(3 x 5) = 30
2(8 x 5) = 80
48 + 30 + 80 = 158
Use the information below to determine if AB and CD are parallel, perpendicular or neither.
(0, – 4), (-1, — 7), (3, 0), (-3, 2)
Answer:
perpendicularStep-by-step explanation:
Calculate the slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Let m₁ and m₂ are the slopes of AB and CD.
Then
if m₁ = m₂ → lines are parallel
if m₁ · m₂ = -1 → lines are perpendicular
[tex]A(0;\ -4);\ B(-1;\ -7)\\\\m_{AB}=\dfrac{-7-(-4)}{-1-0}=\dfrac{-7+4}{-1}=\dfrac{-3}{-1}=3\\\\C(3;\ 0);\ D(-3;\ 2)\\\\m_{CD}=\dfrac{2-0}{-3-3}=\dfrac{2}{-6}=-\dfrac{2:2}{6:2}=-\dfrac{1}{3}[/tex]
[tex]m_{AB}\neq m_{CD}[/tex] - no parallel
[tex]m_{AB}\cdot m_{CD}=3\cdot\left(-\dfrac{1}{3}\right)=-\dfrac{3}{3}=-1[/tex] - perpendicular

Hi! I need help multiplying, adding, and subtracting fractions, could someone help meh? ~bewuga
Answer:
yes i can
Step-by-step explanation:
adding fractions you only add the numerator numbers, the denominator numbers stay the same, subtracting fractions you just subtract the numerator as the denominator stays the same, while multiplying you multiply both numerator and denominator
Answer:
addition and subtraction is possible when denominator are same so to make denometor same multiplication is use on both numerator and denominator
Step-by-step explanation:
for example,
5/10+2/5
now we can't add those numbers so
multiply on both on numerator denominator by same number to make denominator same.
look
5*1/10*1 + 2*2/5*2
5/10+4/10.
(addition is possible bcz denominator are same)
(5+4)/10
9/10 is answer

If you bought 1000 shares of a Vanguard Mutual Fund for $145 a share two years
ago and it is now worth $265. How much would you make if you sold the mutual
fund now?
$120,000
$145,000
$265.000
$1,200
Answer:
$120000
Step-by-step explanation:
1000 X 145 = 145000
1000 X 265 = 265000
$265000 - $145000 = 120000

Answer:
match your blanks to the solution below
Step-by-step explanation:
The multiplication of an integer and a fraction has you multiply the integer by the numerator, then express the result over the denominator. At that point, you can reduce the fraction, if possible.
[tex]4\times\dfrac{3}{4}=4\times\left(3\times\dfrac{1}{4}\right)\\\\=(4\times3)\times\dfrac{1}{4}\\\\=12\times\dfrac{1}{4}=\dfrac{12}{4}=3[/tex]
__
Additional comment
Because multiplication is commutative and associative, this can be done in a way that is a little simpler.
[tex]4\times\dfrac{3}{4}=4\times\left(3\times\dfrac{1}{4}\right)\\\\=3\times\left(4\times\dfrac{1}{4}\right)\\\\=3\times\dfrac{4}{4}=3\times1=3[/tex]
Steve is driving 440 miles to visit the Grand Canyon. He drives at an average rate of 55 miles per hour. Explain how you can find the amount of time it will take Steve to get to the Grand Canyon.
Help-
Answer:
8 hours
Step-by-step explanation:
Distance d = 440 miles
Average rate v = 55 miles/hour
Distance = rate x time
440 = 55 x time
time = 440/55 = 8 hours

What value of x makes this equation true? 12 x minus 15 = 6 minus 3 x
Answer:
Exact Form - 7/5
Decimal form - 1.4
Mixed Form 1 2/5
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Step-by-step explanation:
[tex]12x - 15 = 6 - 3x[/tex]
Move all x values to one side of the equation, and all constant values to the other side of the equation, and don't forget to flip the signs when going from left to right or vice versa.
[tex]12 x + 3x = 6 + 15[/tex]
[tex]15x = 21[/tex]
[tex]x = \frac{21}{15} = \frac{7}{5} [/tex]

Answer:
Given function: [tex]f(x)=(x-2)^2 (x+1) (x-4)[/tex]
The factors give us the zeros (x-intercepts) of the graph.
To find the zeros, set the function to zero and solve for x:
[tex](x-2)^2 (x+1) (x-4)=0[/tex]
Therefore,
[tex](x-2)^2=0\implies x-2=0 \implies x=2[/tex]
[tex](x+1)=0\implies x=-1[/tex]
[tex](x-4)=0 \implies x=4[/tex]
So the zeros are at (2, 0) (-1, 0) and (4, 0)
The multiplicity of a zero is the number of times the factor appears in the fully factored form of the polynomial, i.e. the exponent on the corresponding factor.
[tex]x = 2[/tex] has a multiplicity of 2[tex]x=-1[/tex] has a multiplicity of 1[tex]x=4[/tex] has a multiplicity of 1If the zero has an even multiplicity, the graph touches and bounces off the x-axis at that point.
If the zero has an odd multiplicity, the graph crosses the x-axis at that point.
To find the y-intercept, expand the function:
[tex]f(x)=x^4-7x^3+12x^2+4x-16[/tex]
Set [tex]x = 0[/tex] and solve:
[tex]f(0)=(0)^4-7(0)^3+12(0)^2+4(0)-16=-16[/tex]
Therefore, the y-intercept is at (0, -16)
The end behavior of a polynomial function is the behavior of the graph of f(x) as x approaches positive infinity or negative infinity.
As the leading degree is 4 (even) and the leading coefficient is positive, the end behavior of the function is:
[tex]f(x) \rightarrow + \infty \textsf{ as } x \rightarrow - \infty[/tex]
[tex]f(x) \rightarrow + \infty \textsf{ as } x \rightarrow + \infty[/tex]

Two boxes are shaped as right rectangular prisms. The larger box is having a length of 24 cm, a width of 10 cm, and a height of 30 cm. The dimensions of the smaller box are half the dimensions of the larger box. What is the volume of the smaller box? Enter your answer in the box. cm³
Answer:
The volume of the smaller box is 900cm³
Step-by-step explanation:
Given:
larger box dimensions: 24cm by 10cm by 30cm
dimension of smaller box: 1/2 of larger box:
12cm by 5cm by 15cm
Volume of smaller box: Length×Width×Height
=12cm×5cm×15cm
=900cm³

Identify like terms in the expression. 12n-6+p+6n
Answer:
18n+p-6
Step-by-step explanation:
you combine 12 and 6, then put the exponents in order
Hey there!
Like terms are "from the same family"
Let me clarify.
For example. we have an expression "2t+12h-6h"
In this case, 12h and -6h are like terms and 2t and 12h are not like terms.
Here's another example:
r+a-y+4+9-1
The like terms are:
4, 9, and -1
Now that we know what like terms are, let's identify the like terms in the given expression.
The expression is:
[tex]\bold{12n-6+p+6n}[/tex]
What are the like terms?
That's right, 12n and 6n:
[tex]\bold{12n+6n-6+p}[/tex]
[tex]\bold{18n-6+p}[/tex]
Hence, the answer is
[tex]\boxed{\boxed{\bold{18n-6+p}}}[/tex]
Hope everything is clear.
Let me know if you have any other questions; if so, please comment.

Submit
..
Answer:
its D
Step-by-step explanation:
i got it wrong, thank me latter
The projected sales after 2 years will be $389,350 which is the correct answer would be option (D).
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
Last year's store had total sales of $367,000.
The sales are to increase by 3% per year for the next 2 years.
To determine the projected sales in 2 years
The projected sales in next year = 3% of $367,000 + $367,000
The projected sales in next year = (3/100) × 367,000 + 367,000
The projected sales in next year = 11,010 + 367,000
The projected sales in next year = $378,010
The projected sales after 2 year = 3% of $378,010 + $378,010
The projected sales after 2 year = (3/100) × 378,010 + 378,010
The projected sales after 2 years = 11,340 + 378,010
The projected sales after 2 years = $389,350
Thus, the projected sales after 2 years will be $389,350.
