Answer:
6 toppings
Step-by-step explanation:
The t in this equation represents the amount of toppings.
22 + 0.65t = 26
-22 -22
0.65t = 4
0.65t/0.65 = 4/0.65
t = 6
They could get 6 toppings and the total would be $25.90.

There are 20 students
12 are boys
what fraction are boys
Answer:
This will be 12/20
Step-by-step explanation:
You take the number of favourable outcomes (12, as there are 12 boys) and take the number of total outcomes (20, as there are 20 people in total). Then you do the number of favourable outcomes over the number of total outcomes. This equals 12/20. I hope this helps

What is a fraction?A fraction is a part of a whole.
It is expressed as a quotient, in which the numerator is divided by the denominator.
Example: 2/3, 5/7, 1/3
We have,
Total number of students = 20
Number of boys = 12
The fraction of the boys is:
= Number of boys / Total number of students
= 12 / 20
We can write along with its common factors.
= 2 x 6 / 2 x 10
Common values are canceled out from the numerator and the denominator.
= 6 / 10
We can write it as along with its common factor.
= 2 x 3 / 2 x 5
Common factors are canceled out from the numerator and the denominator.
= 3/ 5

Which rational exponent represents a square root?
A. 1 / 2
B. 3/2
C. 1/3
D. 1/4
Answer:
1/2 rational exponent represents a square root.
Therefore, option A is correct.
Step-by-step explanation:
As we know that raising to the one-half power i.e. [tex]\frac{1}{2}[/tex] is the same
as taking the square root.
so [tex]x^{\frac{1}{2}}[/tex] is the same as the square root of [tex]x[/tex].For example, taking the square root of 4 will determine:
[tex]4^{\frac{1}{2}}[/tex]
[tex]\mathrm{Factor\:the\:number:\:}\:4=2^2[/tex]
[tex]4^{\frac{1}{2}}=\left(2^2\right)^{\frac{1}{2}}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0[/tex]
[tex]\left(2^2\right)^{\frac{1}{2}}=2^{2\cdot \frac{1}{2}}[/tex]
so the expression becomes
[tex]4^{\frac{1}{2}}=2^{2\cdot \:\frac{1}{2}}[/tex]
[tex]=2^1[/tex]
[tex]=2[/tex] ∵ [tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^1=a[/tex]
so, 1/2 rational exponent represents a square root.
Therefore, option A is correct.
Answer: A.) 1/2 is the correct answer

a rectangle has a length of x3y4 inches and a width of xy7 inches . Which expression represents the ratio of the length of the rectangle to do width of the rectangle? (NEED HELP ASAP)
Answer:
A. x²/y³
Step-by-step explanation:
Given the following data;
Length = x³y⁴
Width = [tex] xy^{7}[/tex]
Ratio = length/width
[tex] Ratio = \frac{x^{3}y^{4}}{xy{^7}}[/tex]
Simplifying the equation by applying the law of indices (division), we have;
[tex]\frac{x^{3}}{x} = x^{3} - x^{1} = x^{3-1} = x^{2} [/tex]
[tex]\frac{y^{4}}{y^{7}} = y^{4} - y^{7} = y^{4-7} = y^{-3} [/tex]
Hence, rearranging the above values;
[tex] Ratio = \frac{x^{2}}{y^{3}}[/tex]
Therefore, the expression that represents the ratio of the length of the rectangle to the width of the rectangle is A. x²/y³.

. If y varies directly with x when y = -4 and x = 10, determine y when x = 2. Write and equation for the direct variation and determine the value.
Answer:
y = - 0.8
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition when y = - 4, x = 10, then
- 4 = 10k ( divide both sides by 10 )
- 0.4 = k
y = - 0.4x ← equation of variation
When x = 2 , then
y = - 0.4 × 2 = - 0.8
Mike went to the store to buy shirts. The shirts were $45 each. The store was offering the following discount Mike decided to buy 3 shirts. Not including sales tax, how much money did Mike save by buying the shirts at the discounted price?

What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Given the offer,
By 1 at regular price ($45) and get 40% off on two shirt
40 % of 45 ⇒ 0.40 × 45 = $18
So shirt price = 45 - 18 = $27/each
Since 2 shirt buy at this price = 2 × 27 = $54
Money saved = 2×45 - 54 = $36
Hence "Mike saves $36 by buying the shirts at a discounted price".

8. A tire dealer sells Supreme tires for $48 each and Prestige tires for $56 each. During one week, the sales for both tires totaled $2008. If 11 Prestige tires were sold, write and solve a linear equation to find the number of Supreme tires sold.
Answer:
31 Supreme tires were sold.
Step-by-step explanation:
Cost of one Supreme tire = $45
Cost of one Prestige tire = $56
Total sales = $2008
Let x represent quantity of supreme tyre
Let y represent quantity of Prestige tyre
So, the equation will be:
[tex]45x+56y=2008[/tex]
11 Prestige tires were sold, write and solve a linear equation to find the number of Supreme tires sold.
So, we are given y= 11 and we need to find value of x using above equation
[tex]45x+56y=2008\\45x+56(11)=2008\\45x+616=2008\\45x=2008-616\\45x=1392\\x=\frac{1392}{45}\\x=30.933\\ x\approx31[/tex]
So, 31 Supreme tires were sold.

A complex number is a number system that extends the real numbers with a particular element labelled "i" known as the imaginary unit. The correct option is D.
What is a complex number?A complex number is a number system that extends the real numbers with a particular element labelled "i" known as the imaginary unit, and satisfies the equation i² = -1; every complex number may be represented as a + bi, where a and b are real numbers.
To find the conjugate of a complex number, we change the sign of the complex part of the number. Therefore, the conjugate of -14-2i is -14+2i.
The modulus of the given complex number -14-2i is,
|z| = √[(-14)²+(-2)²]
= √(196 + 4)
= √200
= 10√2
Hence, the conjugate and modulus of –14 – 2i are -14+2i and 10√2, respectively.
