One pair of corresponding sides of 2 similar triangles are 3 and 8 inches long, respectively. If the perimeter of the smaller triangle is 12 inches, what is the perimeter, in inches, of the larger triangle?
Answers
Answer:
Step-by-step explanation:
3 12
8
96 = 3x
x=32. the perimeter is 32
The perimeter of the larger triangle is 32 inches.
What are Similar Triangles?
Similar Triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides.
Let the perimeter of the larger triangle would be x.
We know that the ratio of the corresponding sides is 3/8.
The perimeter of the smaller triangle is 12 inches
We can use the ratio of corresponding sides to find the length of the sides of the larger triangle.
So 3/8 = 12/x
3x = 96
x = 96/3
x = 32
Thus, the perimeter of the larger triangle would be 32 inches.

Suppose the class sizes in high schools in a major public school district are normally distributed with an unknown population mean and standard deviation. If a random sample of 28 high school classes is taken to estimate the mean class size, use a calculator to find the t-score that should be used to find a 90% confidence interval estimate for the population mean.
Answers
Answer:
1.703
Step-by-step explanation:
The reason we try to find t score is because the sample size is below 30, meaning the sample size is small
Hence:
Step 1
We find the degree of freedom
The Degrees of freedom = Number of samples - 1
The random number of samples = 28
= 28 - 1
= 27
Step 2
Using a t score table or t score calculator, we can obtain the t score value for a 90% confidence interval and degree of freedom of 27
90% confidence interval =
10% significance level = 0.10 for two tails or 0.1/2 = 0.05 for one tail
Hence: t90 = 1.703

A piece of string is 3-5 m long. Joe cuts three pieces from it,
each 70 cm long. How much of the original piece is left?
Answers
Note: It seems you mean a piece of string is 3.5 long. So, I am assuming that a piece of string is 3.5 cm long.
Answer:
140 cm of the original piece is left after Joe cuts three pieces.
Step-by-step explanation:
Given the piece of string
3.5mAs we know that
3.5m = 350 cmso the length of a piece of string = 350 cm
As joe cuts three pieces from it, and each 70 cm long.
so the total length of three pieces which were
cut by joe = 70cm + 70cm + 70cm = 210 cm
So, subtracting the total length of the three pieces that were cut from the total length of the string:
350 cm - 210 cm = 140 cm
Therefore, 140 cm of the original piece is left after Joe cuts three pieces from it.

Anthony drew a picture of the front view of a doghouse using two congruent triangles and a rectangle, as shown in the diagram. 3 in. 4 in. 12 in. What is the area of the picture of the doghouse in square inches?
Answers
Answer:
66 in.
Step-by-step explanation:
the rectangle has an area of 48in. because 4x11 = 48. The triangles have a base of 6 because 12 ÷ 2=6. the formula for area of a triangle is BxHx1/2 and the height is 3in so 6x3= 18 and 18x1/2=9 and there is two triangles and the other has the same area. Then you add up the area of everything so 48+9+9 = 66

Answer:
$648.00 or you can say that you made $48 from simple interest
Step-by-step explanation:
Plug the numbers into the formula A = P(1 + rt) and solve,
First, convert to a decimal
r = R/100 = 8%/100 = 0.08 per year.
Solving the equation:
A = 600(1 + (0.08 × 1)) = 648
A = $648.00
