Answer:
History test
Step-by-step explanation:
28 divided by 40 is 0.7 which equals 70 percent.
39 divided by 60 is 65 percent .
Answer:
Phil did better on his History test.
Step-by-step explanation:
In the history test, he scored a 28/40. There are many ways to do this, but here is my way. Convert this to decimal to make comparison easy.
28/40 = 0.7
In the Geography test, he scored 39/60. Convert this to decimal as well.
39/60 = 0.65.
Since 0.7 > 0.65, Phil did better on his history test.

Answer:
f(x) = -|x| + 1.
Step-by-step explanation:
You get this by inverting the graph of f(x) = |x| then moving it up 1 unit.
f(x) = -|x| + 1.
By invert I mean reflect in the x-axis.

What percent of 12 is 48?
Answer: 25%
Step-by-step explanation:
Simplify and express
[tex]2 \sqrt{2} - \frac{3}{ \sqrt{2} } + \frac{4}{ \sqrt{8} } [/tex]
as a single surd
First a few reminders:
• For a ≠ 0 and b ≥ 0, [tex]\sqrt[a]{b}=b^{\frac1a}[/tex]
• 4 = 2² and 8 = 2³
• For real numbers a, b, c, we have [tex](a^b)^c=a^{bc}[/tex]
• For any real numbers a and n (so long as both are not zero), we have [tex]\frac1{a^n}=a^{-n}[/tex]
• For any numbers a, b, c, [tex]a^b\times a^c=a^{b+c}[/tex]
So we have
[tex]\sqrt2=2^{\frac12}[/tex]
[tex]\dfrac1{\sqrt2}=2^{-\frac12}[/tex]
[tex]\dfrac1{\sqrt8}=\dfrac1{(2^3)^{\frac12}}=2^{-\frac32}[/tex]
Then the given expression can be rewritten as
[tex]2\sqrt2-\dfrac3{\sqrt2}+\dfrac4{\sqrt8}=2\times2^{\frac12}-3\times2^{-\frac12}+2^2\times2^{-\frac32}[/tex]
[tex]2\sqrt2-\dfrac3{\sqrt2}+\dfrac4{\sqrt8}=2^{1+\frac12}-3\times2^{-\frac12}+2^{2-\frac32}[/tex]
[tex]2\sqrt2-\dfrac3{\sqrt2}+\dfrac4{\sqrt8}=2^{\frac32}-3\times2^{-\frac12}+2^{\frac12}[/tex]
Pull out a factor of [tex]2^{-\frac12}[/tex]:
[tex]2\sqrt2-\dfrac3{\sqrt2}+\dfrac4{\sqrt8}=2^{-\frac12}\left(2^{\frac32+\frac12}-3+2^{\frac12+\frac12}\right)[/tex]
Simplify this:
[tex]2\sqrt2-\dfrac3{\sqrt2}+\dfrac4{\sqrt8}=2^{-\frac12}\left(2^2-3+2^1\right)=2^{-\frac12}(4-3+2)=3\times2^{-\frac12}=\dfrac3{\sqrt2}[/tex]
Rationalize this last result to get the square root out of the denominator:
[tex]2\sqrt2-\dfrac3{\sqrt2}+\dfrac4{\sqrt8}=\dfrac3{\sqrt2}\times\dfrac{\sqrt2}{\sqrt2}=\dfrac{3\sqrt2}{(\sqrt2)^2}=\boxed{\dfrac{3\sqrt2}2}[/tex]

According to historical data, it is believed that 12% of American adults work more than one job. To investigate if this claim is still accurate, a random sample of 100 American adults is selected. It is discovered that 18 of them work more than one job. A researcher would like to know if the data provide convincing evidence that the true proportion of American adults who work more than one job differs from 12%. What are the values of the test statistic and P-value for this test?

The grades for 200 students at a middle school are represented in the graph below how many more students earned Cs then Ds
Answer:
B. 60
Step-by-step explanation:
There are a total of 200 students here, and 45% got Cs, to find how many got Cs, multiply 200 by 45%, or 0.45: 200*0.45 = 90, 90 people got Cs.
15% got Ds, multiply 200 by 15%, or 0.15 to get 30, 30 got Ds
The amount who got Cs minus the amount who got Cs is 90 - 30 = 60, 60 more students got Cs than Ds

Shamika bought 3 skirts that cost $25 each before the discount. What was her total after thediscount?
A. $45.00
B. $48.75
C. $52.50
D. $56.25
Answer:
The answer is C and please give me brainliet And a like!
Where the above parameters are given, Shamika's total after the discount is $56.25. (Option D)
How to compute the above resultAccording to the table, if the total purchases are less than $50, the discount is 25%.
Shamika bought 3 skirts at $25 each, so her total purchase amount is 3 * $25 = $75.
Since $75 is less than $50, she qualifies for a 25% discount.
To calculate the discount, we multiply the total purchase amount by the discount rate -
Discount = 25% of $75 = (25/100) * $75 = $18.75
To find her total after the discount, we subtract the discount from the total purchase amount -
Total after discount = Total purchase amount - Discount
Total after discount = $75 - $18.75 = $56.25
Therefore, Shamika's total after the discount is $56.25. (Option D)

What are Factors of a Number?
Numbers that divide an original number evenly or precisely are known as its factors. A factor is a whole number that can divide a larger number in two equal parts. A factor is a number that divides another number, leaving no remainder
Given data ,
The number = 42
The number has both negative and positive factors
The factors of the number 42 are
The positive factors of 42 are 1 , 2 , 3 , 6 , 7 , 14 , 21 , 42
The negative factors of 42 are -1 , -2 , -3 , -4 , -6 , -7 , -14 , -21 , -42
Product of -14 and -3 = -14 x -3

A label is placed around the juice box below, not including the bases. Determine the surface area of the label
Answer:
3 In²
Step-by-step explanation:
Talking about surface area, the total area of an object is taken into consideration.
NB: Kindly check the attached picture for the diagram of the 3D object.
In this question, the surface area has to be determined and we will have to take into consideration all the area of the 3D object given in the question.
Surface Area = 6 × k².
Surface area = 6 × ( 1.8 × 1.8) cm².
Surface Area = 19.44 cm².
The next thing to do here is to convert the cm² to in². Therefore, 19.44 cm² ------> x in².
19.44 × 0.155 in² = 3 in².

The sum of the expressions (-10x³ + 4x + 5) + (5x² - 2x) is -10x³ + 5x² + 2x + 5.
Thus, option (D) is correct.
In mathematics, an expression is a combination of numbers, variables, and operators (such as addition, subtraction, multiplication, division, and exponentiation) that represents a mathematical statement.
To find the sum of the given expressions (-10x³ + 4x + 5) and (5x² - 2x).
Simply combine like terms:
(-10x³ + 4x + 5) + (5x² - 2x)
Combining the like terms, we have:
-10x³ + 5x² + (4x - 2x) + 5
Simplifying further, we get:
-10x³ + 5x² + 2x + 5
Therefore, the sum is: [tex]-10x^3 + 5x^2 + 2x + 5[/tex].
