Mr. Walters asked his students to order 89, 708, 37, and 93 from least to greatest, and to be ready to explain the process they used to order the numbers.One student, Brianna, ordered the numbers correctly, and when Mr. Walters asked her to explain her process, she said, “The numbers 89, 37, and 93 are less than 100, so they are all less than 708, since that is greater than 100. Also, 37 is the least because it comes before 50 and the other two numbers are close to 100. Then 89 is less than 90, but 93 is greater than 90.”Which of the following best describes the strategy on which Brianna’s explanation is based?
A cube has a volume of (0.75xy)3 cubic centimeters.
What is the volume of the cube expressed as a fraction?
Answer:
[tex]\frac{27}{64} x^{3} y^{3} cm^{3}[/tex]
Step-by-step explanation:
0.75 means 75/100 which is equal to 3/4.
Cube of 3/4 is [tex]\frac{3^{3} }{4^{3} }[/tex]= 27/64
x cube means x will be multiplied with itself thrice, which is [tex]x^{3}[/tex]and following the same logic, y cube means y will be multiplied with itself three times which is [tex]y^{3}[/tex]. The unit [tex]cm^{3}[/tex]at the last is very important, because, without it, the value does not show that this value is used to represent a volume so we write the units after writing the value.

Amy, Bob, and Carl were using flour from a 7 cup container. Amy used 0.15 of the total container , Bob used 30% of the total container, and Carl used .5 cups of the container. Determine the amount that each person uses and list them from least to greatest.
Answer:
Amy, Carl, bob
Step-by-step explanation:
Amy = 7 - 0.15 = 6.45
Bob = 7 - 0.30 = 6.70
Carl = 7 - 0.5 = 6.5
Order from least to greatest is:
Amy (6.45)
Carl (6.5)
Bob (6.7)
Given the tunction
f(x)= - x^2 + 4x - 3 ,find the rate of chango over the interval [-2,7] (you can take the negative leading coefficlent off for reg ed if you want) *
Answer:
-1
Step-by-step explanation:
Given function: [tex]f(x)=-x^2+4x-3[/tex]
[tex]\implies f(-2)=-(-2)^2+4(-2)-3=-15[/tex]
[tex]\implies f(7)=-(7)^2+4(7)-3=-24[/tex]
[tex]\textsf{Average rate of change}=\dfrac{f(b)-f(a)}{b-a}\quad\textsf{for}\:a\leq x\leq b[/tex]
Therefore, average rate of change over the interval -2 ≤ x ≤ 7
[tex]\implies \textsf{Average rate of change}=\dfrac{f(7)-f(-2)}{7-(-2)}=\dfrac{-24-(-15)}{9}=-1[/tex]

What is the equation of the line that passes through the point (-6, -3) and has a
slope of 0
Answer:
Answer: the equation of the line is y=−3.
Step-by-step explanation:
Since the slope equals 0, then the line is horizontal.
This means that the equation of the line doesn't contain x.
Thus, the equation of the line is y=−3.

Write an equation in point-slope form for the line that passes through the points (f, g) and (h,j).
Point-slope form is a form of a linear equation: [tex]y-y_1=m(x-x_1)[/tex]
[tex](x_1,y_1)[/tex] is a point that falls on the linem is the slope of the lineTo write an equation in point-slope form:
Calculate the slope of the line by solving for mPlug m into the general equationPlug a point that falls on the line in the general equation as [tex](x_1,y_1)[/tex]Solving the QuestionWe're given:
The line passes through the points (f,g) and (h,j)Solve for the slope (m):
[tex]y-y_1=m(x-x_1)[/tex]
⇒ Plug in the point (f,g) as (x,y):
[tex]g-y_1=m(f-x_1)[/tex]
⇒ Plug in the point (h,j) as (x₁,y₁):
[tex]g-j=m(f-h)[/tex]
⇒ Isolate m by dividing both sides by (f-h):
[tex]\dfrac{g-j}{f-h}=m[/tex]
⇒ Therefore, the slope of the line is [tex]\dfrac{g-j}{f-h}[/tex].
Plug the slope into the general equation:
[tex]y-y_1=\dfrac{g-j}{f-h}(x-x_1)[/tex]
Plug one of the points, (f,g) or (h,j) into the equation as (x₁,y₁):
[tex]y-j=\dfrac{g-j}{f-h}(x-h)[/tex]
AnswerThere can be multiple answers for this question, depending on what we consider to be (x,y) and what we consider to be (x₁,y₁). This is one of the possible answers, for (f,g) is (x,y) and (h,j) is (x₁,y₁):
[tex]y-j=\dfrac{g-j}{f-h}(x-h)[/tex]
A basket contains 40 mangoes out of which 8 are rotten. Find the percentage of the mangoes that are in good condition
There are 80% of mangoes which are good condition.
What is percentage?Percentage is a relative value indicating hundredth parts of any quantity.
Given that, A basket contains 40 mangoes out of which 8 are rotten.
Mangoes in total = 40
Number of mangoes which are rotten = 8
Mangoes which are good condition = 40-8 = 32
Percentage of good mangoes = 32/40x100 = 80%
Hence, 80% of mangoes are not rotten.

A rectangle has a length of 10 cm and a width of 7 cm. What is its perimeter?
44 cm
70 cm
34 cm
17 cm
Answer:
34 cm
Step-by-step explanation:
Keep in mind that the perimeter of a rectangle is the sum of the measures of its sides. This means that the sum of the longer sides and the shorter sides is the perimeter of the rectangle.
Let "L" represent the longer side (length) of the rectangle and "S" represent the shorter side (width) of the rectangle.
⇒ Perimeter of rectangle = L + S + L + S
⇒ Perimeter of rectangle = 2(L) + 2(S)
⇒ Perimeter of rectangle = 2(L + S)
Now, let's substitute the length and the width in the perimeter and simplify.
⇒ Perimeter of rectangle = 2(10 + 7) [L = 10; S = 7]
⇒ Perimeter of rectangle = 2(17)
⇒ Perimeter of rectangle = 34 cm
Answer: 70 cm
Step-by-step explanation: 10 x 7 = 70

write the equation of line through (3,6) and (-4,-1)
Answer:
y=x+3
Step-by-step explanation:
The slope of a line passing through the two points P = (x1, y1)and Q = (x2, y2) is given by
m= (y2-y1)/(x2-x1)
We have that x1= 3, y1= 6, x2= - 4, y2= - 1
so m = 1
Now, the y-intercept is b=y1-mx1 (or b=y2-mx2, the result is the same).
b=6-(1)(3)
b=3
Finally, the equation of the line can be written in the form
y = mx+b
y=x+3
Placing a down payment on a home is a common practice among homebuyers and, in many cases, is required by the lender for eligibility reasons. As the Payans’ real estate agent suggested in part C, it’s also important to help keep the mortgage payment low and within the homebuyer’s monthly budget to avoid the risk of default. Write two to three sentences summarizing what might happen if the Payans were to default on their monthly mortgage payments.
Answer:
If the Payans were to default, their credit score could be lowered. The Payans could also lose their house. With both of those things on their record, it would make it harder for the Payans to qualify for another loan.
