Answer:
m = 24
Step-by-step explanation:
m + 7° + 2m + 11° = 90°
3m + 18° = 90°
3m = 90°- 18°
3m = 72
(divide both sides by 3)
therefore : m = 24
79=2m+m+7
79=3m+7
79-7=3m
72=3m
72/3=3m/3
24=m

We can calculate the probability of picking a red marble by:
- adding all the marbles together
- then subtract the amount of red marbles by the number found previously.
2 + 3 + 5 = 10
10 - 5 = 5
5 is what of 10?
5 is 50% of 10.
50% means 0.5 out of 1.
Your answer is 0.5.

The amount of money in a bank account increased by 15.8% over the last year. If the amount of money at the beginning of the year is represented by n, which expression represents the amount of money in the bank account after the increase?
Answers
Answer:
The expression represents the amount of money in the bank account after the increase is: x=1.158n.
Step-by-step explanation:
With the information provided, you can say that the amount of money in the bank after the increase would be equal to multiplying the amount at the beginning of the year for the result of adding up 1 plus the percentage of the increase, which would be:
x=n*(1+0.158)
x=n*1.158
x=1.158n, where:
x is the amount of money in the bank account after the increase
n is the amount of money at the beginning of the year

B
rolling a six-sided cube and drawing 6 marbles out of a bag.
С
tossing a coin and choosing an odd number between 1 and 7
D
drawing 1 card out of 25 cards and choosing a letter out of the alphabet.
Answers
Set of events " rolling a six-sided cube and drawing 6 marbles out of a bag " have an equally like chance of occurring.
Option B is correct.
Probability:Probability of series of experiments shown below;
A. When spinning a spinner with 3 sections then probability of one section is [tex]\frac{1}{3}[/tex] .
When tossing a coin, then probability of getting head or tail is [tex]\frac{1}{2}[/tex]
So that, set A has not equally like chance of occurring.
B. When rolling six-sided cube, probability of getting one number is [tex]\frac{1}{6}[/tex]
When one marble is drawn out of 6 marble in a bag, then probability is [tex]\frac{1}{6}[/tex]
Therefore, set B has equally like chance of occurring.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,

Answers
Answer:
$260,437.50
$108,750
Step-by-step explanation:
Here is the complete question :
Fill in the book value at the end of year 1 under each depreciation method when residual value is $36,000 and useful life is 4 years: Depreciation method:
Straight-line $335,250
Units-of-Output
Double-declining $217,500
Book value = cost of the asset - first year depreciation expense
Straight line depreciation expense = (Cost of asset - Salvage value) / useful life
(335250 - 36,000) / 2 = $74,812.50
Book value = $335,250 - $74,812.50 = $260,437.50
Depreciation expense using the double declining method = Depreciation factor x cost of the asset
Depreciation factor = 2 x (1/useful life) = 2/4 = 0.5
$217,500 x 0.5 = 108,750
Book value = $217,500 - 108,750 = $108750

Answers
Answer:
14 forks and 19 spoons
Step-by-step explanation:
Let us represent:
Number of forks = x
Number of spoons = y
Gabriella's custom kitchen supplies sell handmade forks and spoons it costs the store 1.20 to buy the supplies to make a fork and 1.20 to buy the supplies to make a spoon. Last April her store spent 39.60 on materials for forks and spoons
Hence:
1.20x + 1.20y = 39.60.....Equation 1
The store sells forks for 4.60 and spoons for 4.00. They sold the finished products for a total of 140.40.
4.60x + 4.00y = 140.40......Equation 2
Hence:
1.2x + 1.2y = 39.6.....Equation 1
4.6x + 4y = 140.4....Equation 2
Multiply Equation 1 by 4 and Equation 2 by 1.2
4.8x + 4.8y = 158.4...Equation 3
5.52x + 4.8y = 168.48.....Equation 4
We subtract Equation 3 from 4
0.72x = 10.08
x = 10.08/0.72
x = 14 forks
Solving for y using Equation 1
x = 14
1.2x + 1.2y = 39.6.....Equation 1
1.2 × 14 + 1.2y = 39.6
16.8 + 1.2y = 39.6
1.2y = 39.6 - 16.8
1.2y = 22.8
y = 22.8/1.2
y = 19 spoons
Therefore, they made
14 forks and 19 spoons
