Answer:
1/6
Step-by-step explanation:
First convert 4.2m to cm
100cm = 1m
x = 4.2m
x = 4.2 * 100
x = 420cm
70cm to 420cm = 70/420
70/420 = 7/42
7/42 = 1/6
Hence 70 cm as a fraction of 4.2 m is 1/6
Which point is located at 2/4 on the number line??
Answer:
on C
Step-by-step explanation:
The point K is located at 2/4.
What is fraction?"It is a number expressed as a quotient, in which a numerator is divided by a denominator."
For given example,
We have been given a fraction 2/4.
We simplify given fraction 2/4 as
2/4
= 1/2
=0.5
Also, the midpoint of 0 and 1 is,
(0 + 1)/2 = 0.5
In the given graph the midpoint of 0 and 1 is denoted by K
Therefore, the point K is located at 2/4.

ΔABC is similar to ΔFED. Answer the questions to find the length of DF .
1. Which side in ΔFED does AB in ΔABC correspond to?
Write your answer in the space below.
2. Which side in ΔFED does CB in ΔABC correspond to?
Answer:
1.AB are the first 2 letters in ΔABC. Similarly, FE are the first 2 letters in ΔFED.
Hence side AB corresponds to side FE.
2.CB are the last 2 letters in ΔABC. Similarly, DE are the last 2 letters in ΔFED.
3.AC corresponds to FD
4.The scale factor is 2 because you would take the sides in ABC and multiply by 2 to get the sides in FED
5.6 because it corresponds to CB and you would multiply the side of CB (3) by 2 and you would get 6
6.A^2+B^2=C^2 = FE^2+ED^2=FD^2 = 8^2+6^2=100^2 = square root of 100= 10
The side length of FD is 10

The top running speed of a giraffe is 250% of the top speed of a squirrel. If a squirrel’s top running speed is 12 miles per hour, find the speed of a giraffe.
Answer:
30
Step-by-step explanation: First take the fastest speed of the squirrel, and then you multiply it by the percentage (250%). You can this by moving on decimal point to the left from the zero (250% = 2.50). Then multply the speed of the squirrel by said percentage of the girrafe,
12 x 2.5 = 30

Answer:
15%

In the first week of July, a record 1,120 people went to the local swimming pool.In the second week, 100fewer people went to the pool than in the first week. In the third week,140 more people went to the pool than in the second week. In the fourth week, 208 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
Answer:
15%
Step-by-step explanation:
Given that:
Number of people who went to swimming pool in the first week = 1120
In second week, there are 100 fewer people, so
Number of people who went to swimming pool in the second week = 1020
In third week, there are 140 more people, so
Number of people who went to swimming pool in the third week = 1160
In fourth week, there are 208 fewer people, so
Number of people who went to swimming pool in the fourth week = 952
To find:
Percentage decrease in the number of people who went to the pool over the four weeks?
Solution:
Initial value = 1120
Final value = 952
Decrease in the value = Final value - Initial value
Decrease in the value = 1120 - 952 = 168
To find the percentage, we need to take the initial value in the consideration.
Therefore, percentage decrease is:
[tex]\dfrac{Decrease}{Initial\ value}\times 100[/tex]
[tex]\Rightarrow \dfrac{168}{1120}\times 100\\\Rightarrow \bold{15\%}[/tex]

A boy at an amusement park has 38 ride tickets. Each ride on the roller coaster costs 5 tickets. After riding the roller coaster as many times as he can,how many tickets will the boy have left?
Answer:
He will expend 35 tickets for 7 rides. 3 tickets are left.
Step-by-step explanation:
Giving the following information:
Number of tickets= 38
Tickets per ride= 5
To calculate the number of rides he can make, we need to use the following formula:
Number of rides= number of tickets / tickets per ride
Number of rides= 38/5
Number of rides= 7.6 = 7 rides
He will expend 35 tickets for 7 rides. 3 tickets are left.

Mary uses 212 cups of lemonade concentrate to make 20 servings of lemonade. How many servings can Mary make using 1 gallon of lemonade concentrate? Please include an explanation :)
Answer:
number of servings = 1.5
Step-by-step explanation:
1 gallon = 16 Cups
cups of lemonade concentrate : lemonade servings
212 cups : 20 servings
How many servings can Mary make using 1 gallon of lemonade concentrate
Let
x = number of servings
cups of lemonade concentrate : lemonade servings
16 cups : x servings
Equate both ratios to get x
212 : 20 = 16 : x
212 / 20 = 16 / x
Cross product
212 * x = 20 * 16
212x = 320
x = 320 / 212
= 1.5094339622641
Approximately 1.5 servings

2 is the right answer.2y + 3y = 4 - 6 - 13
Answer:
y=-3
Step-by-step explanation:
2y+3y=4−6−13
2y+3y=4+−6+−13
(2y+3y)=(4+−6+−13)
5y=−15
5y=−15
y= −3
Answer:
y = -10
Step-by-step explanation:
You add 2y and 3y, you'd get 5y from it. You do 4-6-13 which is -15.
So 5y = -15.
You subtract 5 from the y side and add 5 to the -15.
So basically:
5y = -15
-5 & +5
y = -10

Answer:
(3x+21)(x-5)
Step-by-step explanation:
To solve this let's create an equation that has intercepts at -7 and 5
To do this we get the following
(x+7)(x-5)
Now we need to make sure that the line passes through (4,-33) To do so we will plug in 4 to see how far off we are
If you plug in 4 into x you should get -11
To make y= -33 we simply need to put a three in the front and then distribute it to the first bracket
So we have
3(x+7)(x-5)
then distribute the 3 to get
(3x+21)(x-5)

Answer:
4+4+4
Step-by-step explanation:
ok so 4^3 is essentially saying 4x4x4 and 4 x 4^2 is saying 4 x 4 x 4 which is the same as 4x4x4. it is all multiplying the number 4 by itself 3 times if you try and do all three of those you will get the same answer which is 64. However if you add 4+4+4 you will get 12. I hope that makes some sense

PLEASE HELP! The vertices of square LMNO are L(0, 2), M(2, 0), N(0,−2), and O(−2, 0). Which of the following shows that its diagonals are congruent perpendicular bisectors of each other? I ATTACHED THE IMAGES.
Answer:
The fourth one is correct.
Step-by-step explanation:
To show the diagonals are congruent, calculate their lengths using the Distance Formula: d=(x2−x1)2+(y2−y1)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√.
Find the length of LN.
Substitute 0 for x1, 2 for y1, 0 for x2 and −2 for y2.
LN=(0−0)2+(−2−2)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√
=02+(−4)2‾‾‾‾‾‾‾‾‾‾√
=8‾√
Find the length of MO.
Substitute 2 for x1, 0 for y1, −2 for x2 and 0 for y2.
MO=(−2−2)2+(0−0)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√
=(−4)2+02‾‾‾‾‾‾‾‾‾‾√
=8‾√
Since LN=MO, by the definition of congruent line segments, LN=MO.
To show the diagonals are perpendicular, calculate their slopes using the Slope Formula: m=y2−y1x2−x1.
Find the slope of LN.
Substitute 0 for x1, 2 for y1, 0 for x2 and −2 for y2.
m1=−2−20−0=−40⇒m1 cannot be defined.
Find the slope of MO.
Substitute 2 for x1, 0 for y1, −2 for x2 and 0 for y2.
m2=0−0−2−2
=0−4
=0
The slope of LN cannot be defined, this means that LN is parallel to y-axis. The slope of MO is equal to 0, this means that MO is parallel to x-axis. x and y axis are perpendicular, therefore LN⊥MO.
The figure shows the same square L M N O on a Cartesian plane as in the beginning of the task. Diagonal L N is perpendicular to diagonal M O.
To show the diagonals bisect each other, calculate their midpoints using the Midpoint Formula: P(x1+x22,y1+y22).
Find the midpoint of LN.
Substitute 0 for x1, 2 for y1, 0 for x2 and −2 for y2.
P1(0+02,2+(−2)2)=(0, 0)
Find the midpoint of MO.
Substitute 2 for x1, 0 for y1, −2 for x2 and 0 for y2.
P2(2+(−2)2,0+02)=(0, 0)
Both midpoints are the same point on the coordinate plane. This means the two diagonals intersect at their midpoints, or bisect each other.
The figure shows the same square L M N O on a Cartesian plane as in the beginning of the task. The diagonals intersect at point P. Segments L P, P N, M P, and P O are congruent.
Therefore, the diagonals are congruent perpendicular bisectors of each other.
