what is the unit rate of 1/7 and 1/21 ? this is very confusing?
Answer:
the unit rate of 1/7 is itself (1/7), and for 1/21 is 1/21.
Step-by-step explanation:
this is because these rates/ratios are unit fractions. so if the numerater is 1, theres nothing you can do to simplify it.
you can check with the ceaser method as well, but you're still going to find the same solution.
plus, for example, if it takes 7 grams of sugar to make 1 cake, it wouldnt make sense for 1 gram of sugar to make 7 cakes.
hope this helped clear up your confusion <3

A pole that is 2.8 m tall casts a shadow that is 1.46 m long. At the same time, a nearby building casts a shadow that is 50.25 m long. How tall is the building?
Round your answer to the nearest meter.
Answer:
96 m
Step-by-step explanation:
Create a proportion where x is the height of the building:
[tex]\frac{2.8}{1.46}[/tex] = [tex]\frac{x}{50.25\\}[/tex]
Cross multiply and solve for x:
1.46x = 140.7
x = 96
So, the height of the building is approximately 96 m tall

15) A small rectangular block of land has a perimeter of 100 m and an area of 225 m². Find the dimensions of the block of land.
Answer:
45 and 5 are the dimensions of the block of land.
Step-by-step explanation:
2(x + y) = 100, x + y = 100/2, y = (50 - x)
xy = 225
x (50 — x) = 225
0 = x^2 — 50x + 225
0 = (x — 45) (x -5)
45 and 5 are the roots of the above polynomial, thus they are the sides or dimensions of the block of land.

Given the form of the equation 3x + 2y = 3 and x – 3y = -10. Then determine the result of 3x - y !
Answer:
-6
Explanation:
x= -1 and y=3
3x- y
=> 3(-1)-3 = -3-3= -6
Answer:
3x – y = -6
Step-by-step explanation:
To solve on the problem above, you can do it by substitution and elimination of the two equations.
3x + 2y = 3
➡️ 3x + 2.3 = 3
➡️ 3x + 6 = 3
➡️ 3x = -3
➡️ x = -1
➡️ 3x – y = 3(-1) – 3
➡️ = -3 – 3 = -6 ✅

-√100/5 = ? Simply it please with full explanation. Thanks
Answer:
-2√5
Step-by-step explanation:
First simplify what's inside the radical: 100/5=20
Now we have -√20
The square root of 20 is 2√5 (because 5*4=20 and the square root of 4 is 2)
Because there is a negative the answer has to be -2√5

7x-10y=3. Is this a
reasoning.
good model? Explain your reasoning.
Answer:
7x-10y=6
Step-by-step explanation:
Firstly, supervise 7x-10y=3 using the coordinates of one from the known points
7*8-10*5=3
6=3 It is not correct, so the equation is uncorect
Find the correct equation
The common equation is y=mx+b
5=8m+b
-9=-12m+b
Both equations are simultaneous.
-9-5= -12m+b- (8m+b)
-14=-20m
m=0.7
b=5-5.6=-0.6
y=0.7x-0.6
0.7x-y=0.6
7x-10y=6- the correct answer
Find the number of faces, edges, and vertices of this shape.

which of the following is equivalent to 7x+5<-2(4x-3)
x>11
-x<1
15x<-11
15x<1
Answer:
7x+5< -8x+6
=15x<1
The equivalent inequality is 15x<1. Therefore, option D is the correct answer.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is 7x+5<-2(4x-3).
Now, 7x+5<-8x+6
Subtract 5 on both the sides of an inequality, we get
7x<-8x+1
Add 8x on both the sides of an inequality, we get
7x+8x<1
15x<1
Therefore, option D is the correct answer.

11 Alicia buys a car that costs $26610, and she makes a $3140 down payment on it. How much
does she still owe on the car? Give units.
Answer:
$23,470
Step-by-step explanation:
A down payment is how much you pay upfront for a car. So, how much she still owes will be the difference between the total cost and the down payment. Therefore, subtract $3,140 from $26,610; 26610-3140=23470. Then, since you are talking about money the units are dollars, $.

Show your work in details if you can, I have a hard time understanding this.
Answer:
Step-by-step explanation:
x/2 - 7 = 9 Add 7 to both sides

x/2 = 16 Multiply both sides by 2
2*x/2 = 16*2
x = 32
You are at about the second stage of solving equations. So far what you should know is that you should add or subtract before doing multiplication or division.
Take a much simpler question
x - 8 = 10 What do you do here? You can't multiply or divide. So add
+8 8
x = 18
Now try what you have
2x - 5 = 11 Add before multiplication or division
5 5
2x = 16 Divide by 2
2x/2 = 16/2
x = 8

Answer and Step-by-step explanation:
Essentially, you are describing the position of point K using the location of the other points on the graph.
Let's start listing some descriptions:
K is:
3 more than H
2 more than J
3 less than L
4 less than M
7 less than N
