In a class of 20 students, 17 of the students
passed a prerequisite skills quiz What percent of
the students passed the quiz?

Answers

¹⁷⁄₂₀ × 100 = 85

Answer = 85%

The correct answer is [tex]\(\frac{17}{20} \times 100\%\)[/tex].

To find the percentage of students who passed the quiz, we need to divide the number of students who passed by the total number of students, and then multiply by 100 to convert the fraction to a percentage.

 Given that 17 students passed out of 20, the calculation is as follows:

[tex]\[ \text{Percentage of students who passed} = \left( \frac{\text{Number of students who passed}}{\text{Total number of students}} \right) \times 100\% \][/tex]

[tex]\[ \text{Percentage of students who passed} = \left( \frac{17}{20} \right) \times 100\% \][/tex]

 This fraction can be simplified to a decimal or a mixed number if necessary, but it is most accurate and precise in its fractional form as given above. To convert it to a decimal, one would divide 17 by 20 and then multiply by 100, which would yield 85%. Thus, 85% of the students passed the quiz.

15 - 2(3 - 2x) = 46

Answers

Answer:

x=33

Step-by-step

subtract 15 and 2 you get 13

13 times 3 =39

subtract 39 with 39 and 46 with 39

at the end you will get -26x=7

reverse negative into positive and then add -26 with 26 and you will be left with x and then you add 7 with 26 and your answer is

x=33

-2(3-2x) = 46-15
-2 (3-2x) = 31
3-2 = -31/2
-2x = -31/2 - 3
-2x = -37/2
X = 37/2/2
X = 37/2 x 2
X= 37/4

the graph of y= -4×+7 is​

Answers

Answer:

Step-by-step explanation:

The graph of y= -4×+7 is​ a straight line with slope -4 and y-intercept 7.  Please do not use × to represent the independent variable; use x instead.  × represents multiplication.

To graph this function, first plot the y-intercept, b, which is (0, 7).

Next, starting with your pencil point at (0, 7), move the point 1 unit to the right and plot another point (which will be (1, 7) ).  Now move your pencil point 4 units down and plot your third point, which will be (1, 3).

Finally, draw a straight line thru the first and third points, that is, thru (0, 7) and (1, 3).  Notice how this line has the slope -4 and the y-intercept (0, 7).

Answers

Answer:

Step-by-step explanation:

We can multiply powers with the same base

x^4⋅x^2=(x⋅x⋅x⋅x)⋅(x⋅x)=x^6

Final answer:

Properties of exponents are rules used to simplify mathematical expressions involving exponents. Examples are Power of a Power which means adding exponents when multiplying two expressions with the same base, and Quotient of Powers which is subtracting exponents when dividing two expressions with the same base.

Explanation:

The question is about the properties of exponents. In mathematics, the properties of exponents refer to the rules that guide how expressions involving exponents are handled. For example, when you multiply two expressions with the same base, you add the exponents (also known as the Power of a Power property). So, an exponent like x^3 * x^2 simplifies to x^(3+2) = x^5.

Another example is the quotient of powers property, where you subtract the exponents when dividing two expressions with the same base. So, an expression like x^5 / x^3 simplifies to x^(5-3) = x^2.

These are just a couple of the basic properties of exponents. Other properties include the power of a product, the power of a quotient, zero exponent, and negative exponent. Each of these properties follows specific rules to simplify the expression involving exponents.

Charmaine will run less than 26 miles this week. So far, she has run 18 miles. What are the possible numbers of additional miles she will run? Use t for the number of additional miles she will run. Write your answer as an inequality solved for t

Answers

Answer:

18+t<26

t={1,2,3,4,5,6,7}

Step-by-step explanation:

18+t<26

alright, so you know that she will run less than 26. That means she cannot run 26 or 27 or any more miles than that.

She can run 19, 20, 21, 22, 23, 24, or 25 miles in total from her starting point which is 18.

She already ran 18 miles. If she ran one more it would be 19, if she ran 2 more it could be 20. But she CAN NOT pass 25 miles. (it is not less than OR equal to)

so let me put it like this:

18+1<26 yes because 18+1=19 which is less than 26

18+2<26 yes because 18+2=20 which is less than 26

18+3<26 yes because 18+3=21 which is less than 26

18+4<26 yes because 18+4=22 which is less than 26

18+5<26 yes because 18+5=23 which is less than 26

18+6<26 yes because 18+6=24 which is less than 26

18+7<26 yes because 18+7=25 which is less than 26

18+8<26 NOOO because 18+8=26 which is NOT less than 26 (it's equal, not less than)

The period for which the mortgage offered is 30 years.

The rate for which the mortgage offered is 5 percent.

The interest on the loan is $5.37 for every $1000 financed.

Monthly payment

Monthly payment is the principal and interest payment for each year for $1000 financed.

The sides of a triangle are a + 3 ¼, 2a, and 7 ½ - a. If a = 4 1/8, what is the length of each of the three sides? Also, find the perimeter of the triangle showing steps for your work.

Answers

Answer: Side one is 7 3/8

Side two is 8 2/8

Side three is 3 3/8

Perimeter is 19

Step-by-step explanation:

The first side is    a+3 1/4

the second side is  2a

The third side is   7 1/2-a

Plug 4 1/8 in for a

First side   4 1/8+3 1/4

Find the common denomnator which is 8

4 1/8+3 2/8

7 3/8

First side is 7 3/8

Second side  2(4 1/8)=4 1/8 +4 1/8= 8 2/8

Third side is 7 1/2-4 1/8

Find the common denominator which is 8

7 4/8-4 1/8= 3 3/8

Third side is 3 3/8

The perimeter is adding all the three sides together

7 3/8+8 2/8+ 3 3/8=18 8/8

Reduce 18 8/8=18 +1=19

Answer:

Perimeter = 19 units

Step-by-step explanation:

Given a = 4 1/8

[tex]Side1 = a + 3\frac{1}{4}\\Side2 = 2a\\Side3 = 7\frac{1}{2}-a[/tex]

The next step is substituting the a value in the expressions:

[tex]Side1 =  4\frac{1}{8}+ 3\frac{1}{4}\\Side2 = 2*(4\frac{1}{8})\\Side3 = 7\frac{1}{2}-4\frac{1}{8}[/tex]

Then, fractions with different denominators must be converted to the same denominator. Also, the multiplication of a whole number by a mixed number can be done by using distributive law:

[tex]Side1 =  4\frac{1}{8}+ 3\frac{2}{8}\\Side2 = 8\frac{2}{8}\\Side3 = 7\frac{4}{8}-4\frac{1}{8}[/tex]

[tex]Side1 =  7\frac{3}{8}\\Side2 = 8\frac{1}{4}\\Side3 = 3\frac{3}{8}[/tex]

Now, the perimeter is the sum of all the sides. Therefore, the perimeter is:

[tex]Perimeter =  7\frac{3}{8} + 8\frac{1}{4} + 3\frac{3}{8}[/tex]

Which is 19 units.

Final answer:

The explicit formula for the geometric sequence 12, -36, 108, -324, ... is f(n) = 12 * (-3)^(n-1), where 'n' is the term number.

Explanation:

The series provided is a geometric series. In a geometric series, each term after the first is found by multiplying the previous term by a fixed, non-zero number called the common ratio, denoted by 'r'. In our given series 12, -36, 108, -324, ..., you can determine that the common ratio (r) is -3. Now, using the formula for a geometric sequence given by f(n) = a * r^(n-1), where 'a' is the first term (12 in this case) and 'n' is the term number, we can write the explicit formula as
