Step-by-step explanation:
40% of 36
can somone tell me what it is or how to do it because i am struggling
Answer:
14.4
Step-by-step explanation:
To find 40 percent of 36, here's how I do it. Just divide 36 by one hundred (move the decimal point two times to the left), giving you 0.36. Then multiply that by 40, and you get 14.4! Of course, there are multiple ways to do it, but that's just mine. If it doesn't work for you, try and search some formulas.
Answer:
Step-by-step explanation:
40/100*36
40*36/100
1440/100
14.4
so here if u divide 40% by 100 the % sign will automarically removed and here 40% 0f 36 means 40 and to remove % sign divide it by 100 and multply it by 36

Find the rate of change between:
(1, -1)
(2,4)
Answer:
rate of change=5
Step-by-step explanation:
Hi there!
The rate of change (or the slope) is calculated from two points with the formula (y2-y1)/(x2-x1)
we are given two points: (1,-1), and (2,4)
let's label the points, to avoid confusion:
x1=1
y1=-1
x2=2
y2=4
now substitute into the formula:
*note: remember that we are subtracting the negative numbers. When it's simplified, we add the numbers.
rate of change=(4--1)/(2-1)
simplify:
rate of change=(4+1)/(2-1)
rate of change=5/1
rate of change=5
Hope this helps!

Elijah puts $550 in an account earning 8% simple interest annually. What is the total amount of money he will have in his account after 6 years, if no withdrawals or deposits are made?
Answer:
814?
Step-by-step explanation:
Simple interest is I = PRT, so you can multiply the 550, by 1.08 by 6 to get the total.
The principal is 550, the rate is 0.08 (using 1.08 because the prior gives interest, and using a whole 1 with it will be the total), and the time is 6 years because the interest is simple annual.
use 0.08 instead of 1.08 when solving for interest.
Tammy knits blanket and scarves. On the first day of a craft fair, she sells 2 blankets and 5 scarves for $104
Answer:
Cost of Blanket = 32
Step-by-step explanation:
Let the cost of a blanket be = b , cost of a scarf be = s. Blanket price x Blanket Quantity & Scarf Price x Scarf Quantity sum up to be total sales.
So, Day 1 : 2b + 5s = 104 (i) , Day 2 : 3b + 4s = 128 (ii)
Solving equations : Multiplying (i) by 3 , & (ii) by 2 , we get
6b + 15s = 312 ,
(-)6b + (-)8s = (-)256
By elimination method, 15s - 8s = 312 - 256 → 7s = 56 → s = 56 / 7 = 8 .
Putting s value in any equation i], 2b + 5 (8) = 104 → 2b + 40 = 104 → 2b = 104 - 40 = 64 → b = 64 / 2 = 32

Tickets for the basketball game were sold at 4$ for adults and 2.50$ for students. If 320 tickets were sold for a total of 1100$, how many students tickets were sold? How many adult tickets were sold?
Answer: Number of students tickets were sold = 120
Number of adults tickets were sold = 200
Step-by-step explanation:
Let x= Number of adults, y = Number of students
As per given,
x+y=320 ...(i)
4x+2.5y=1100 ...(ii)
Multiply 2.5 on both the sides of (i), we get
2.5x+2.5y=800 ...(iii)
Subtract (iii) from (ii), we get
1.5x=300
[tex]x=\frac{300}{1.5}\\x=200[/tex]
From (i) y= 320-200 = 120
Hence, Number of students tickets were sold = 120
Number of adults tickets were sold = 200
Tom has some marbles in two bags. In one bag he has 3 yellow, 2 green and 1 red marble. In the other bag he has 3 yellow, 3 green and 3 red marbles. If Tom takes one marble out of each bag, how probable is it that neither one is yellow?
Answer:
1 /3
Step-by-step explanation:
Bag 1 :
Yellow = 3 ; green = 2 ; red = 1
Total = 6
P(not yellow) = (2 +1) / 6 = 3/6 = 1/2
Bag 2 :
Yellow = 3 ; green = 3 ; red = 3
Total = 9
P(not yellow) = (2 +3) / 9 = 6/9 = 2/3
P(neither yellow from the two bags) = 1/2 * 2/3 = 2 /6 = 1/3
The interior angle measure of a regular polygon is calculated with the following formula, where n represents the number of sides or interior angles of the regular polygon.
Determine the measure of the interior angles of a regular octagon and identify whether or not a regular octagon can be used as the only shape in a regular tessellation.
144°, no
135°, yes
144°, yes
135°, no
THE RIGHT ANSWER IS A 144°, no
Answer:
Step-by-step explanation:
The interior angle measure of a regular polygon is calculated with 180*(n-2)/n, where n represents the number of sides.
A regular octagon has 10 sides so it interior angle = 180*(10-2)/10
= 144
A tessellation is a tile pattern with the same polygon repeating. The polygon's interior angles must combine to form 360 degree. A regular octagon has interior angle of 144 degree which does not add to 360 degree. So a regular octagon cannot be used as the only shape in a regular tessellation.
The answer is 144°, no.
Answer:
Step-by-step explanation:
oct means 10
(n-2)/n * 180
= (10-2)/10 * 180
= 144°
144 + 144 = 288 < 360
144 + 144 + 144 = 432 > 360
so a regular octagon can NOT be used as the only shape in a regular tessellation.

Ben and Jerry both have 7 numbers in their data set. Ben's average of his data set is 9. If Jerry average is 2 more than Ben, what does Jerry's data points have to sum to be
Answer:
Jerry's data points have to sum to be 77.
Step-by-step explanation:
We are given that
Ben and Jerry both have total numbers in their data set=7
Average of Ben's data set=9
Average of Jerry's data set=9+2=11
We have to find the Sum of Jerry's data points.
We know that
Average of data=Sum of numbers/Total number of data points
Using the formula
Average of Jerry' data =Sum of numbers in data/7
11=Sum of numbers in data/7
Sum of numbers=[tex]11\times 7[/tex]
Sum of numbers=77
Hence, sum of Jerry' data points=77
At a particular school 10% of children travel by bus.If this represent 120 children how many children attend the school?
Answer:
Total number of students= 1,200
Step-by-step explanation:
Giving the following information:
Proportion of students= 10%
Number of students that travel by bus= 120
To calculate the number of students that attends school, we need to use the following formula:
Total number of students= Number of students that travel by bus / proportion of students
Total number of students= 120 / 0.1
Total number of students= 1,200

Since the triangle has a right angle, we can find the length of the unknown side using the trigonometric notations SOH CAH TOA where;
Sin Ф = opposite side/hypotenuses side
Cosine Ф = adjacent side/hypotenuses side
Tangent Ф = opposite side/adjacent side
With respect to ∠B given that ∠D=90°,
BD is the adjacent side and CB is the hypotenuse side, DC is the opposite side
Hence ,Sin B = 15/17
