Answer:
B = 2A/H where b is height, h is height, and a is the area of triangle.
Step-by-step explanation:
A=1/2bh
A=1/2bh (multiply by 2/1 on both side to cancel out on the right side)
2A = bh (divide by h to isolate the b)
2A/h = b (reorder the equation)
B = 2A/H where b is height, h is height, and a is the area of triangle.

Which work correctly uses properties of inequality to find the solution to –0.4x – 10 > 14?
–0.4x – 10 > 14
–0.4x > 4
x > –10
–0.4x – 10 > 14
–0.4x > 24
x > –60
–0.4x – 10 > 14
–0.4x > 4
x 14
–0.4x > 24
x < –60
Answer:
d
Step-by-step explanation:
–0.4x – 10 > 14
–0.4x > 24
x < –60
the correct solution to the inequality – 0.4x – 10 > 14 is x < – 60.
Inequality refers to a mathematical relationship between two values that are not equal.
The correct work that uses properties of inequality to find the solution to – 0.4 x – 10 > 14 is:
– 0.4 x – 10 > 14
Subtract 10 from both sides:
– 0.4 x > 24
Divide both sides by – 0.4 (note the change in inequality direction when dividing by a negative number):
x < – 60
Therefore, the correct solution to the inequality – 0.4x – 10 > 14 is x < – 60.

A math class consists of 25 students, 14 female and 11 male. Two students are selected at random to participate in a probability experiment. Compute the probability that no males are selected.
[tex] \LARGE{ \underline{ \orange{ \bf{Required \: answer:}}}}[/tex]
In the die the total no. of students are 25
Number of possible outcome for no males = Number of possible outcomes for females only = 14We know that,
∴ P(E) = Number of favourable outcome / Number of all possible outcome
Here we have to find the probability of the event of finding the no. of males.
⇛ P(E) = 14 / 25 (Answer)
And we are done !!
Probability helps us to know the chances of an event occurring. The probability that no males are selected is 0.3033.
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given that A math class consists of 25 students, 14 female and 11 male. Two students are selected at random to participate in a probability experiment.
Now, since we need to compute the probability that no males are selected, which can also be taken as the probability of both the students selected are girls. Therefore, the probability can be written as,
Probability = (14/25) × (13/24)
= 182/600
= 0.3033
Hence, the probability that no males are selected is 0.3033.

Write the equation 5x=2y+10 in the slope-intercept form and find the slope of a line parallel to it.
Answer:
slope intercept form: y=-5/2x+5
the slope of a parallel line would have m=-5/2
Step-by-step explanation:
to get in slope intercept form, you solve for y and get it alone. first you subtract 5x from both sides to get y alone. then you simplify by dividing by 2.
Parallel lines have the same slope

It takes 30 mins to shape 10 pots, and heating all 10 pots takes 10 mins. Add 30 and 10 minutes to get: 40 minutes.
Answer:
3p + 10; 40 minutes
Step-by-step explanation:
It takes 3 minutes to shape one pot.
It takes 3p minutes to shape p pots.
A batch of pots has p pots and takes 10 minutes in the kiln.
The total time it takes to make 1 batch is the time to shape the pots, 3p, plus the time in the kiln, 10 minutes.
The expression is
3p + 10
For a batch of 10 pots, p = 10.
3p + 10 = 3(10) + 10 = 30 + 10 = 40
Answer: 3p + 10; 40 minutes

The length of a rectangle is 5 inches more than the width. The perimeter is 46 inches. Find the length and the width.
The length is inches___ and the width is_____ inches.
Answer:
width: 9 inches
length: 14 inches
Step-by-step explanation:
width: x
length: x + 5
perimeter = 2L + 2W
46 = 2(x + 5) + 2x
46 = 2x + 10 + 2x
46 = 4x + 10
36 = 4x
x = 9
width: 9
