Answer:
The answer is 5/8
Step-by-step explanation:
The area of the entire figure below is 1 square unit.
What is the area of the striped rectangle?
Answer:
3/4 * 2/5
Step-by-step explanation:
Areas is L * W
(1/5 + 1/5) * (1/4 + 1/4 + 1/4) = 2/5 * 3/4
Answer:
3/10
Step-by-step explanation:
The area will be the length of the striped rectangle multiplied by the width of the striped rectangle.
The length will be 1/4 + 1/4 + 1/4 = 3/4 and the width will be 1/5 + 1/5 = 2/5.
Now just multiply 3/4 by 2/5 and you'll get 6/20 which in its simplest form is 3/10.

The weight of Jack is 30kg 500g. The weight of Dereck is 28kg 700g. What is their total weight? Also, find the difference of their weight?
Answer:
Below.
Step-by-step explanation:
30 kg 500g + 28kg 700g
= 58kg + 1200g
= 59kg 200g.
Difference
= 30 kg 500g - 28kg 700g
= 2kg + 500 - 700
= 2kg - 200g
= 1kg 800g.

Step-by-step explanation:
what is the product of 3 square root 7 and 17 square root 14 in simplest radical form
[tex]3 \sqrt{7} \times 17 \sqrt{14} [/tex]
This is the problem that we need to solve. The best way to get about it is to first:
Multiply the constant numbers (3 and 17). 3×17 is 51. Next multiply the radicals. [tex] \sqrt{7} \times \sqrt{14} = \sqrt{7 \times 14} = \sqrt{108} [/tex]Simplify the squareroot of 108 since it is 49 times 2. It would be equal to 7 squareroots of 2. Our final answer would be:[tex]51 \times 7\sqrt{2} = 357 \sqrt{2} [/tex]51 x 7 is 357, so the answer above is right.The skills needed are multiplication, mulitplication of radicals, and simplifying radicals, so if you want to review anything use these as reference.
Hope you understood and have a nice day!!

A single card is drawn at random from a standard 52 card deck.
Work out the following probabilities in their simplest form:
P(8)
=
P(not 8)
=
Answer:
Step-by-step explanation:
P(8)
There are 4 eights in a standard deck (no jokers) So the probability is 4/52 = 1/13 = 0.0769
P( ~ 8)
48 cards in a standard deck are not 8
P( ~8) = 12/13 = 0.9231

The question is not complete
Brenda's school is selling tickets to a spring musical. On the first day of ticket sales the school sold 3 senior citizen tickets and 9 child ... The school took in $67.00 on the second day by selling 8 senior citizen tickets and 5 child tickets. What is the price each of one senior citizen ticket and one child ticket?
Given data
let senior citizens be x
and children be y
so
3x+9y= 75--------------1
on the second day
8x+5y= 67------------2
solve 1 and 2 above
3x+9y= 75 X8
8x+5y= 67 X3
24x+72y=600
-24x+15y=201
0x+57y= 399
divide both sides by 57
y= 399/57
y= $7
put y= 7 in eqn 1 above
3x+9*7= 75
3x+63= 75
3x=75-63
3x=12
x= 12/3
x= $4
Which is shorter? 3/6 of a minute or 2/6 of an hour?
Answer:
3/6 of a minute
Step-by-step explanation:
3/6 can also be simplified to 1/2. So, 1/2 of a minute is 30 seconds. 2/6 can be simplified to 1/3. So, 1/3 of an hour is 20 minutes. 30 seconds is very much shorter than 20 minutes. Thus, 3/6 of a minute is shorter than 2/6 fo an hour.
help???????????????????
Answer:
Please check the explanation.
Step-by-step explanation:
Part a)
Given
m∠ABD = (7q - 46)°m∠CBD = (3q + 6)°It is clear that m∠ABD and m∠CBD lie on a straight line.
Thus, the sum of m∠ABD and m∠CBD will be 180°.
Hence,
m∠ABD and m∠CBD are supplementary angles.
Part b)
As m∠ABD and m∠CBD are supplementary angles, so the sum of m∠ABD and m∠CBD will be 180°.
Thus,
m∠ABD + m∠CBD = 180°
substitute m∠ABD = (7q-46)° and m∠CBD = (3q + 6)°
(7q-46)° + (3q + 6)° = 180°
Part c)
Given the equation
(7q-46)° + (3q + 6)° = 180°
Combining the like terms
7q + 3q - 46 + 6 = 180
10q - 40 = 180
10q = 180 + 40
10q = 220
divide both sides by 10
10q/10 = 220/10
q = 22
Therefore, the value of q = 22
Part d)
As
m∠ABD = (7q-46)°
substituting q = 22
m∠ABD = 7(22) - 46
= 154 - 46
= 108°
also
m∠CBD = (3q + 6)°
substituting q = 22
m∠CBD = 3(22) + 6
= 66+6
= 72°
Therefore,
m∠ABD = 108°m∠CBD = 72°5x -9y =-26

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define Systems
5x - 9y = -26
-2x + 3y = 11
Step 2: Rewrite Systems
-2x + 3y = 11
Multiply everything by 3: -6x + 9y = 33Step 3: Redefine Systems
5x - 9y = -26
-6x + 9y = 33
Step 4: Solve for x
Elimination
Combine 2 equations: -x = 7Divide -1 on both sides: x = -7Step 5: Solve for y
Define equation: 5x - 9y = -26Substitute in x: 5(-7) - 9y = -26Multiply: -35 - 9y = -26Add 35 on both sides: -9y = 9Divide -9 on both sides: y = -1Answer:
x= -7
y= -1
Step-by-step explanation:
5x-9y= -26..............(1)
-2x+3y= 11...............(2)
5(-2x+3y= 11)
-10x +15y = 55................(3)
2(5x-9y= -26)
10x-18y= -52.....................(4)
Add equation 3&4
-10x+15y= 55
10-18y= -52
-3y= 3
y= -1
put y= -1 into equation ............(3)
-10x+15y= 55
-10x+15(-1)= 55
-10x-15 = 55
-10x= 55+15
-10x= 70
x= -7
Therefore;
x= - 7 and y= - 1
Questions related on indices. ( I need a full explanations of how the answer is found. )
Answer:
(a) m = 10
(b) n = 160
Step-by-step explanation:
To rewrite the expression in the manner indicated, write an equation that sets the given expression equal to the desired expression. Then solve for the variable value. The distributive property and the usual rules of exponents apply.
The rules of exponents you can use here are ...
(a^b)(a^c) = a^(b+c)
(a^b)^c = a^(bc)
a^0 = 1
__
(a) 2^101 +2^103 = m×2^100
2^(101-100) +2^(103-100) = m × 2^(100-100) . . . . . . . multiply by 2^(-100)
2^1 +2^3 = m
2 + 8 = m
m = 10
__
(b) 2^101 +2^103 = n×4^48
2^101 +2^103 = n×(2^2)^48 . . . . . substitute 4 = 2^2
2^101 +2^103 = n×2^96 . . . . . . . . simplify
2^5 +2^7 = n . . . . . . . . . . . . . . . . . as above, multiply by 2^(-96)
32 +128 = n
n = 160
_____
Additional comment
The rules of exponents tell you that ...
(m × 2^100) × 2^-100 = m × 2^(100 -100) = m × 2^0 = m
This is effectively the same as dividing by 2^100. You're doing the same thing you would do to solve any linear equation: divide by the coefficient of the variable.

pls help with this question
Answer:
x<56
Step-by-step explanation:
Since the dot over 56 isn't filled in, the inequality doesn't include 56 (so we'll use < or > not [tex]\leq[/tex] or [tex]\geq[/tex])
Now, let's look at the direction of the shading: is it going to the left of 56 or to the right?
This shading is to the left of 56, which indicates that it's all of the numbers less than 56.
As said above, the inequality doesn't include 56
therefore, it will be x<56 (x is less than 56, and 56 is not included)
hope this helps!
Answer:
x<56
Step-by-step explanation:
First off look at the number the dot is on.
Its at 56.
So next we see if the dot is filled in or not.
If the dot is filled in, then its either less than equal to or greater than equal to
If the dot is empty, then its less than or greater than
The dot is not filled in
So next see which way the line is going
The line is going left, which means that the number is getting smaller
Make the equation
start with x
x
The sign will be < because x has to be less than 56.
x < 56
An easy trick to remember which way the sign goes in these types of questions [not in all cases though] is look which way the line is going.
Think of the signs as arrows
If you have < then the line goes <-- left
If you have > then the line goes --> right
If you need further assistance, don't be afraid to reach out. I hope this helps!

a) 6
b) 11
c) 18
d) 1
Answer:
11
Step-by-step explanation:
11 fred
6 louis
18 tom
please mark me as brainliest!!<3
Answer:
Fred Painted 11 chairs. B
Step-by-step explanation:
Let Tom = T
Let Louis = L
Let Fred = F
Formulas
T = 3*L
F = L + 5
T + L + F = 35 Subtitute for Fred and Tom
Solution
3*L + L + L+5 = 35 Combine like terms
5L + 5 = 35 Subtract 3 from both sides
5L = 35 - 5
5L = 30 Divide by 5
L = 30/5
L = 6
Fred Painted 5 more than Louis.
That makes Fred = 11
