Answer:
Base = 3 cm
Step-by-step explanation:
Area of a triangle = [tex]\frac{1}{2} bh[/tex]
Let h = height
base = 2 times the height - 5; b = 2h-5
Area = 6 cm²
A = [tex]\frac{1}{2}bh[/tex]
[tex]6 =\frac{1}{2}(2h - 5)(h)[/tex] Multiply 2h(h) -5(h)
[tex]6 (2) = 2(\frac{1}{2})(2h^{2} - 5h[/tex] Multiply both sides by 2 to remove the fraction
12 = 2h²- 5h
2h ² - 5h - 12 = 0 Set the equation = 0 and factor
(2h + 3)(h - 4) = 0
2h + 3 = 0 or h - 4 = 0
2h = -3 h = 4
h = -3/2 or h = 4 Answer can not be negative so h = 4cm
The base is 2(4) - 5; The base = 8 - 5; base = 3 cm
You are doing chores to earn your allowance. For each chore you do, you earn $5. You are saving up to buy a $100 lego set. How many chores would it take you to earn $100?
Answer:
It would take 20 chores.
Step-by-step explanation:
1 chore = $5
=> 1 x 20 = $100
=> 20 chores = $100
Therefore, it would require me 20 chores to save $100 and buy that Lego set.

The number a is about 8 times greater than b.
Find the correct value of a and b.
A. a = 3.1 and b = 2.5
B. a = 2.5 and b = 3.1
C. a = 2 and b = 1.2
D. a = 1.2 and b = 2
Answer: None of the answers are viable.
Step-by-step explanation:
a ≅ 8b
a/b ≅ 8
A. (3.1/2.5) = only slightly greater than 1
B. 2.5/3.1 = slightly less than 1
C. (2/1.2) = less than 2
D. 1.2/2 = less than 1
None of these answers is viable.
None of the options are correct.
Given,
The number a is about 8 times greater than b.
We need to find the correct value of a and b from the given options.
A. a = 3.1 and b = 2.5
B. a = 2.5 and b = 3.1
C. a = 2 and b = 1.2
D. a = 1.2 and b = 2
What do the mathematical terms mean?We have,
2 times M = 2x M
2 greater than M = M + 2
2 less than M = M - 2
Sum = adding
Times = Multiplication
Find the value of a and b.
We have,
The number a is about 8 times greater than b.
We can write it as
a = 8 x b
Find out which option is correct.
A. a = 3.1 and b = 2.5
a = 8 x b
3.1 = 8 x 2.5
3.1 ≠ 20
So this option is incorrect.
B. a = 2.5 and b = 3.1
2.5 = 8 x 3.1
2.5 ≠ 24.8
This option is not correct.
C. a = 2 and b = 1.2
2 = 8 x 1.2
2 ≠ 9.6
This option is not correct.
D. a = 1.2 and b = 2
1.2 = 8 x 2
1.2 ≠ 16
This option is not correct.
Thus none of the options are correct.

Find the slope given two points: (-9, -2) and (-5,0)
Answer:
1/7
Step-by-step explanation:
Consider the line passing through these two points. The increase in x (run) from the first to the second is 14; the increase in y (rise) is 2.
Thus the slope of this line is m = rise/run = 2/14, or m = 1/7
Answer:
[tex]m = \frac{1}{2}[/tex]
Step-by-step explanation:
To find the slope using two given sets of coordinates, the following function can be used:
[tex]m = \frac{y2-y1}{x2 - x1}[/tex]
Where x1,y1 are one set of coordinates and x2,y2 are the other set:
[tex]m = \frac{0 - (-2)}{-5 - (-9)}\\[/tex]
[tex]m = \frac{0 + 2}{-5 + 9}[/tex]
[tex]m = \frac{2}{4}[/tex]
This can be simplified down to:
[tex]m = \frac{1}{2}[/tex]

Find the perimeter. Simplify your answer.
Answer:
6z-30 :D
Step-by-step explanation:
Step-by-step explanation:
The perimeter of a square is just all the sides added up together. To do this we can make an equation.
2(z-5) + 2(2z - 10)
This represents two sides with different lengths two times. To solve, you first use the distributive property to multiply z-5 by 2.
2z - 10 + 2(2z - 10)
We then use the distributive property by multiplying 2z - 10 by 2.
2z − 10 + 4z − 20
We then combine 2z and 4z to get 6z.
6z − 10 − 20
Subtract 20 from 10 to get -30.
6z-30.

Answer:
35 mL = 0.35 dL
950 g = 0.95 kg
Step-by-step explanation:
This is the answer because:
1) For mL to dL, divide the volume value by 100: 35/100 = 0.35
