Answer:
5.6 miles
Step-by-step explanation:
Let's set up a proportion using the following setup.
[tex]\frac{miles }{minutes}=\frac{miles }{minutes}[/tex]
We know Maya can run 7 miles in 80 minutes.
[tex]\frac{7miles }{80minutes}=\frac{miles }{minutes}[/tex]
We don't know how many miles she can run in 64 minutes. Let's say she can run x miles in 64 minutes.
[tex]\frac{7miles }{80minutes}=\frac{x miles }{64 minutes}[/tex]
[tex]\frac{7}{80}=\frac{x}{64}[/tex]
We want to solve for x (miles in 64 minutes). Therefore, we must isolate x on one side of the equation.
x is being divided by 64. The inverse of division is multiplication. Multiply both sides of the equation by 64.
[tex]64*\frac{7}{80}=\frac{x}{64}*64[/tex]
[tex]64*\frac{7}{80}=x[/tex]
[tex]64*0.0875=x[/tex]
[tex]5.6=x[/tex]
[tex]x= 5.6 miles[/tex]
Maya can run 5.6 miles in 64 minutes.

What is rectangular prism?"It is a three-dimensional solid shape which has six faces that are rectangles."
Formula to calculate the volume of rectangular prism:V = l w h, where l is the length, w s the width and h is the height of the rectangular prism.
Given figure consists of two rectangular prisms.
For the smaller rectangular prism,
length(a) = 8 [tex]V_2= 8\times 5\times 5[/tex]cm, width(b) = 8 cm and height(h) = 1 cm
For the larger rectangular prism,
length(p) = 8 cm, width(q) = 5 cm and height(r) = 5 cm
Let [tex]V_1,V_2[/tex] represents the volume of the smaller and larger rectangular prisms respectively.
The volume of the smaller rectangular prism would be,
⇒ [tex]V_1=a\times b\times c[/tex]
⇒ [tex]V_1=8\times 8\times 1[/tex]
⇒ [tex]V_1=64[/tex] cu.cm.
The volume of the larger rectangular prism would be,
⇒ [tex]V_2=p\times q\times r[/tex]
⇒ [tex]V_2=8\times 5\times 5[/tex]
⇒ [tex]V_2 = 200[/tex] cu.cm.
The volume of the figure is:
= [tex]V_1+V_2[/tex]
= 64 + 200
= 264 cubic centimeters
The volume of the figure 264 cubic centimeters.

The Sports Brand Company is making a new shoe that has a wholesale price of $40, and it wishes to advertise a retail price of $89.99. What is the markup percentage? Give answer to nearest whole percent. (hint: change decimal to percent, % will not be typed)
Answer:
Markup Percentage = 125%
Step-by-step explanation:
The wholesale price is $40, the "selling price" is $89.99.
90-40=50 (Profit)
Now that we know the profit , we need to find the percentage.
To find this percentage we can use the formula: (M=Markup percent)
[tex]M=profit/cost*100%[/tex]
In this situation, we can insert PROFIT= 50, Cost=40
M=50/40*100
= 1.25*100
=125%

Is the equation true or false? 27 × 15 = (20 × 15) – (7 × 15) _____
Answer:
This equation is false.
Step-by-step explanation:
27x15=405
You're doing the distributive property here so you're supposed to add but they subtract. Since you're doing 20x15 you have to add because 27-20=7.
The equation 27 × 15 = (20 × 15) – (7 × 15) is false.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The distributive property is the distributed law of multiplication over operations in fundamental algebra, such as adding and subtracting.
The expression is given below.
⇒ 27 × 15
The expression can be written as,
⇒ 27 × 15
⇒ (20 + 7) × 15
⇒ 20 × 15 + 7 × 15
The equation 27 × 15 = (20 × 15) – (7 × 15) is false.

48/4= 12
Hope this helped. ;)
Answer:
12 students are in a group
Step-by-step explanation:
There are 87 first graders, but 39 students are picked up. So, we have to calculate how many students are left.
87 - 39 = 48
There are 48 students left.
The teacher divided these 48 students intro 4 groups.
48 / 4 = 12
So, there are 12 students in a group.

Finda + b, 2a + 3b, |a|, and |a − b|.a = 5i + j, b = i − 2j
Answer:
Step-by-step explanation:
Given the complex notations a = 5i + j, b = i − 2j, we are to evaluate the following:
1) a + b
= 5i+j + (i-2j)
= 5i+j+i-2j
collect like terms
= 5i+i+j-2j
= 6i-j
Hence a+b = 6i-j
2) 2a+3b
= 2(5i+j) + 3(i-2j)
open the parenthesis
= 10i+2j+3i-6j
collect like terms
= 10i+3i+2j-6j
= 13i-4j
Hence 2a+3b = 13i-4j
3) |a| = √x²+y²
Given a = 5i+j; x = 5, y = 1
|a| = √5²+1²
|a| = √25+1
|a| = √26
4) |a-b|
First we need to calculate a-b
= a - b
= 5i+j - (i-2j)
open the parenthesis
= 5i+j-i+2j
collect like terms
= 5i-i+j+2j
= 4i-3j
|a-b| = √4²+(-3)²
|a-b| = √16+9
|a-b| = √25
|a-b| = 5

Calculate the minimum and maximum possible areas. Round your answers to the nearest whole square unit. A rectangular garden plot measures 12 feet by 28.6 feet. The minimum possible area is about ft. The maximum possible area is about ft?
Answer:
i. Minimum is 343 square feet
ii. Maximum is 360 square feet
Step-by-step explanation:
The dimension of the rectangular garden plot is 12 feet by 28.6 feet.
1. The minimum possible area can be determined by;
area of a rectangle = length x width
= 28.6 x 12
= 343.2
The minimum possible area is about 343 square feet.
2. The maximum value can be determined by;
28.6 ≅ 30.0 (1 sf)
area of a rectangle = length x width
= 30 x 12
= 360
The maximum possible area is about 360 square feet.
Which of the following is a rational number? (4 points)
square root 97square root 98, square root 99, square root 100
Answer:
Square root 100
Step-by-step explanation:
A rational number is a number that can be completely expressed by a fraction. In this case, 100 is the only square number so only the square root of 100 will result in a rational number (10) or (10/1). The others are not square numbers so square rooting them will result in a long line of decimal points which cannot be expressed by a fraction.

Answer:
The square root of 100 is a rational number.

The square root of 100 is 10. A rational number is a number that can be made by dividing two integers (whole numbers). 10 ÷ 1 = 10. None of the other options are integers, so they are out.

Why does the problem of finding the zeros (i.e. the inputs where a function assumes the value zero) receive such disproportionate attention in algebra?A. Because the problem of finding where a function f assumes the value c, i.e. solving f(x) = c, is equivalent to finding where the function f(x)-c assumes the value zero; and c = O is the only number for which f(x) = c can be solved by factoring f(x). B. It's because usually you want to know where a function crosses the x-axis. Crossing a different axis parallel to that is just not that interesting. C. It's because knowing the zeros allows you to determine the end behavior of the function, and the vertical and horizontal asymptotes. D. Because O is the lowest value (i.e. the minimum) that a function can assume. In many math applications, we need to know the minimum value of a quantity.
Answer:
The answer is C
Step-by-step explanation:
Why does the problem of finding the "zeros" (the inputs where a function assumes the value of zero OR the value inputs for which the function is equal to zero) of a function receive such disproportionate attention in ALGEBRA?
(D) is wrong because zero is not the minimum value that a function can assume. A function could assume or be equal to a negative number or term and negative figures are less than zero.
The answer is (C) because knowing the zeros of a function allows you to determine the end behaviour of the function and the vertical & horizontal asymptotes on a graph/cartesian plane.
