Answer:
B, 5x - 3 = 12
Step-by-step explanation:
3 less means subtracting, it's going to be -3.
It says 3 less than five times a number, meaning we don't know the number, so we can put it as x.
3 less means your subtracting from something, which would make it 5x - 3.
Finally, they state that it equals 12, making the equation 5x - 3 = 12.

How to solve for a missing side length of a triangle (NOT a right triangle) when one side is 4m and another side is 3m, and the only angle is 120 degrees?
Answer:
c ≈ 6.08 m
Step-by-step explanation:
Your question is how to solve for a missing side length of a triangle when given 2 sides length and an angle. The side length can be solved using the cosine rule . We use cosine rule to find the length of a side of a triangle when given two sides and an included angle.
The cosine rule formula for finding a side length are as follows
c² = a² + b² - 2ab cosC
b² = a² + c² - 2ac cosB
c² = a² + b² - 2ab cosC
Using cosine rule
c² = 4² + 3² - 2 × 4 × 3 cos 120°
c² = 16 + 9 - 24 cos 120°
c² = 25 - 24 (-0.5)
c² = 25 + 12
c² = 37
square root both sides
c = √37
c = 6.0827625303
c ≈ 6.08 m
Which point gives the y-intercept of f(x) = - x2 + 4x - 3?
A) (-3,0)
B) (0,3)
C) (0.-3)
D) (3,0)
Answer:
The y intercept is (0,-3)
Step-by-step explanation:
The y intercept is when x =0
f(x) = - x^2 + 4x - 3
f(0) = 0 +0 -3
f(0) =-3
The y intercept is (0,-3)

Fifty percent of what number is 12.5?
A. 25
B. 6.25
C. 15
D. 55
Answer:
A) 25
Step-by-step explanation:
12.5 x 2 = 25
- if 50 percent is 12.5
then 100 percent is 12.5 x 2
Answer:
A. 25
Step-by-step explanation:
50% of 25 is 12.5. The word, "of" can be used as multiplying. 50% in decimal form is 0.5, and you multiply 0.5 times all of the answers until you get 12.5 as the answer, which is why A is correct.

Help me with question 21 to get brainliest
Step-by-step explanation:
We can call the original value x. In 2012, the painting's value was 1.05 x. In the beginning of 2013, the value was (1.05 x) * 0.98, and that increased to (1.05x) * 0.98 * 1.40 at the end of 2013. When we simplify, we get 1.4406 x as a value, and we know that this is equal to $52,640. We can write 1.4406x = 52640, and when we solve for x, we get x ≈ $36415.38. Hope this helps!

Step 1) Divide the figure into separate shapes
Triangle: 4 x 4
Large rectangle: 19 x 8
Small rectangle: 7 x 5
Long rectangle: 4 x 7
Step 2) Find the area of each shape
Triangle: A = 1/2 x 4 x 4 = 8
Large rectangle: A = 19 x 8 = 152
Small rectangle: A = 7 x 5 = 35
Long rectangle: A = 4 x 7 = 28
Step 3) Add all of the areas of the shapes together
A = 8 + 152 + 35 + 28 = 223 square feet

Can you explain how to find the dimensions fro this rectangle
Answer:
Width = 4.5
Length = 7.5
Step-by-step explanation:
The perimeter is two times the length plus two times the width.
So 2(x+3) + 2x = 24 is the equation to solve.
2x+6+2x = 24
4x = 24-6
4x = 18
x = 9/2= 4.5
So the width = 4.5
Length = 4.5+3 = 7.5
Answer:
Length = 7.5 and width =- 4.5.
Step-by-step explanation:
We have the equation:
P = 2L + 2W where P = perimeter, L = length and W = width.
Here P = 24, L = x + 3 and W = x
So plugging in the given values:
24 = 2(x + 3) + 2x
4x + 6 = 24
4x = 24 - 6 = 18
x = 4.5.
So the dimension ar length = x + 3 = 7.5 and width = 4.5.
I predict it will take 23 minutes to drive to my grandma's house today. It actually takes 24 minutes. What is the percent error? Round to the nearest thousandth.
Answer:
4.167%
Step-by-step explanation:
Given: It was predicted that it will take 23 minutes to drive to grandma's house but it actually takes 24 minutes.
To find: percent error
Solution:
Predicted time = 23 minutes
Actual time = 24 minutes
Error is the difference between Approximate and Exact Value. Percentage Error is used to compare an estimate value to an exact value.
Error = 24 - 23 = 1 minute
Percent error = (error/actual time) × 100
= 4.167%

find the mean and median and made of the following data 30,31,35,29,32,30,31,35,36,35
Answer:
mean- 32.4
median- 31.5
mode- 35
Step-by-step explanation:
to find mean add up all the number together than divide it by how many number that are there
for example the total is 324 and you would divide it by 10 (since there are 10 number there)
to find median locate the middle number but since you have two number in the middle take those to number add them together and divide by 2
for example 31+32=63 than divide by 2 which is 31.5
to find mode it is the number that appears most often so it would be 35 since it appears most often

p = 7000 is the amount deposited, aka the principal
r = 0.15 is the decimal form of 15% interest rate
t = 2 is the number of years the money sits in the account
--------------
B = p*(1+r)^t
B = 7000*(1+0.15)^2
B = 7000*(1.15)^2
B = 7000*(1.3225)
B = 9257.50
Subtract off the deposited amount to get the interest earned
i = B - p = 9257.50 - 7000 = 2257.50

What is the probability of picking an even number and then picking an even number?
Simplify your answer and write it as a fraction or whole number.
Answer:
Probability of picking an even and then even number = [tex]\frac{1}{6}[/tex]
Step-by-step explanation:
Probability of picking a card with even number,
P(even 1) = [tex]\frac{\text{favorable outcomes}}{\text{Total outcomes}}[/tex] = [tex]\frac{\text{even cards}}{\text{Total number of cards}}[/tex]
= [tex]\frac{2}{4}[/tex]
= [tex]\frac{1}{2}[/tex]
Followed by picking a card which is even without putting the first card back.
So an even card is to be picked out of remaining 3 cards.
P(even 2) = [tex]\frac{\text{favorable outcomes}}{\text{Total outcomes}}[/tex]
= [tex]\frac{1}{3}[/tex]
Now probability of both events = P(even 1) × P(even 2)
= [tex]\frac{1}{2}\times \frac{1}{3}[/tex]
= [tex]\frac{1}{6}[/tex]
Therefore, probability of both the events will be [tex]\frac{1}{6}[/tex].
