The volume of the given triangular prism to the nearest tenth is; 171.5 in³
What is the Volume of the triangular prism?
The volume of a triangular prism of the kind given to us is expressed as;
Volume of a triangular prism = area of base triangle × length of the prism
Now, the formula for area of base triangle is;
Area = 1/2 * base * height
From the question, we have;
base = 9.8 in
height = 14 in
Now, the length of prism is 2.5 inches. Thus;
Volume of prism = (1/2 * 9.8 * 14) * 2.5
Volume of prism = 171.5 in³

How many times as great is the value 1.5 than the value of 0.15 Explain
Answers
The number of times the value 1.5 exceeds the value 0.15 is 10, which is obtained by dividing both values.
How do you calculate how many times a number is greater?We divide a by b to find how many times greater a number is than b; thus, to calculate how many times greater a number is, we use a division operation.
What exactly is a number comparison?To determine how many times greater a number is than b, we compare them, i.e. divide them.
As an example:
50/10 = 5, indicating that 50 is five times greater than ten.
We must determine how many times the value 1.5 is greater than the value 0.15.
For this , let us divide 1.5 by 0.15
Number of times the value is greater = 1.5/0/15
= 10
Therefore, the number of times the value 1.5 is greater than the value 0.15 is 10.

Find the simple interest and the total amount after three years.Principal = 11,750 rupeesAnnual rate of interest = 7.5%Total interest = (rupees)Total amount=(rupees)
Answers
The formula for calculating simple interest is expressed as
I = PRT
where
I represents the interest
P represents the principal or initial amount invested
R represents the interest rate
T represents the time in years
From the information given,
P = 11750
R = 7.5%
Recall, percentage is expressed in terms of 100. Thus,
R = 7.5/100 = 0.075
T = 3
By substituting these values into the formula,
I = 11750 x 0.075 x 3
I = 2643.75
Total interest = 2643.75 rupees
Total amount = principal + total interest

A. 5:30
B. 4:50
C. 6:00
D. 4:10
Answers
when the minute hand rotated through 1260° time will became 5:30 PM
Complete angle:-
A complete angle is a type of angle that measures 360°.A complete angle deals with one full rotation measuring 360°.
In an hour or in 60 minute, minute hand covers a 360° angle.
According to question,
initially it is 2:00PM,that is minute hand at 12 and hour hand at 2
it is given that minute hand has rotated through 1260°
1260° = 3 x 360° + 180°
which means minute hand will have three complete rotation and one half rotation.
when minute hand rotated through 360° angle then hour hand will move from 2 to 3.
And again in second rotation, when minute hand rotated through 360° angle then hour hand will move from 3 to 4.
Again in third rotation, when minute hand rotated through 360° angle then hour hand will move from 4 to 5.
As of now, minute hand have taken three complete rotation and so hour hand reached at 5
Now, when minute hand rotated through 180° (one half rotation),minute hand will reach at 6 from 12.
So, right now the position of hour hand is between 5 and 6 and the position of minute hand at 6.
hence, time will be 5:30 PM

let x be a normally distributed random variable with mean 5 and standard deviation 15. please express your answer as a number between 0 and 100. if you want to write 52%, please enter 52. what is the probability that x is less than or equal to 38?
Answers
The probability that x is less than or equal to 38 is 0.9861.
For a normally distributed set of data, given the mean and standard deviation, the probability can be determined by solving the z-score and using the z-table.
First, solve for the z-score using the formula below.
z-score = (x – μ) / σ
where x = individual data value = 38
μ = mean = 5
σ = standard deviation = 15
z-score = (38 - 5) / 15
z-score = 33 / 15
z-score = 2.2
Find the probability that corresponds to the z-score in the z-table. (see attached images)
z-score = 2.2
probability = 0.9861

By using distributive property, [tex]-3\left(7x^{2}+3x\right) = -21x^{2} -9x[/tex]
This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.
In order to quickly solve equations, a number is distributed across the integers in the brackets. When using the distributive property of multiplication, for instance, to resolve the expression 4(2 + 4), we would do so as follows: 4(2 + 4) = (4 × 2) + (4 × 4) = 8 + 16 = 24.
We have,
[tex]-3\left(7x^{2}+3x\right)[/tex]
Using Distributive Property, A(B+C) = AB+AC
[tex]-3\left(7x^{2}+3x\right) = -21x^{2} -9x[/tex]
Hence, [tex]-3\left(7x^{2}+3x\right) = -21x^{2} -9x[/tex]

What are fractions in math?In mathematics, a fraction is a numerical value that represents a portion of a whole. The entire can be any number, a specific value, or an item. Fractions are written as p/q.
Given:
Total mass of sugar Mr tan has = 2 kg
Fraction of sugar used to make dessert = 1/4 kg
Fraction of sugar used to bake some cakes = 3/5 kg
The total mass of sugar used is calculated as,
= Mass of sugar used to make dessert + Mass of sugar used to bake some cakes
Mass of sugar used to make dessert = (1/4 of 2) kg = 1/2 kg
Mass of sugar used to bake some cakes = (3/5 of 2) kg = 6/5 kg
Total mass of sugar used = (1/2 + 6/5) kg = 17/10 = 1.7 kg
Mass of sugar left = Total mass of sugar - Total mass of sugar used
