Answer:
New width = 12 in.
Step-by-step explanation:
Original height = 2 in.
Original width = 3 in.
New height = 8 in.
New width = x = ?
The shape of the original painting and the shape of the new painting are similar, therefore, the ratio of their corresponding linear measurement will be equal.
Thus:
New height/original height = new width/original width
8/2 = x/3
Cross multiply
2x = 3*8
2x = 24
2x/2 = 24/2
x = 12
New width = 12 in.

16 units, 30 units, V50 units
5 units, 7 units, 174 units
Answers
Answer:
08 units, 3 units, V73 units
Step-by-step explanation:
Pythagoras theorem can be used to determine which sets of side lengths are for a right triangle
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
8² + 15² = √289
8² + 3² = √73
16² + 30² = √1156

The weight of oranges growing in an orchard is normally distributed with a mean weight of 5 oz. and a standard deviation of 0.5 oz. From a batch of 1500 oranges, how many would be expected to weight less than 5 oz., to the nearest whole number?
Answers
Answer:
The interval that would represent weights of the middle 95% of all oranges from this orchard is from 5 oz to 7 oz.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 6
Standard deviation = 0.5
Middle 95% of weights:
By the Empirical Rule, within 2 standard deviations of the mean.
6 - 2*0.5 = 5
6 + 2*0.5 = 7
The interval that would represent weights of the middle 95% of all oranges from this orchard is from 5 oz to 7 oz.
To print tickets, a printer charges a $30 setup fee plus $1.05 per ticket. Write an algebraic expression for the cost of t tickets. What is the cost of 300 tickets?

Answer:
Solution given:
we have
setup price =$30
as rate for 1 print tickets =$1.05/tickets
so
for t
t=$30+$1.05*t
is a required expression.
the
cost of 300 tickets:
300 tickets =$30+$1.05*300=$345
$345is the cost of 300 tickets.

Step-by-step explanation:
3 + 2(15 - 11)
Step 1: use distributive property
2 x 15 = 30
2 x -11 = -22
3 + 30 + (-22)
3 + 30 - 22
Step 2: using PEDMAS, add the first two numbers
3 + 30 = 33
33 - 22
Step 3: subtract the last two numbers
33 - 22 = 11

Answers
Answer: [tex]162,520.588[/tex]
Step-by-step explanation:
Given
The function [tex]y=15,000(1.1)^x[/tex] models the cost of tuition fees after year 2000
In year 2025 that is 25 years after 2000, fees can be given as
[tex]\Rightarrow y=15,000(1.1)^{25}\\\Rightarrow y=15,000\times 10.834\\\Rightarrow y=162,520.588[/tex]
Thus, the fees in year 2025 is [tex]162,520.588[/tex].

Answer:
See below
Step-by-step explanation:
A plane is a flat, two-dimensional surface that extends infinitely.
A point is a precise location on a plane.
A line is a one-dimensional figure that has only its length that extends infinitely.
Points are collinear if they all fall on the same straight line.
Points or lines are coplanar if they all fall on the same plane.
Line segments are a line with two endpoints on each end of the segment, which have a definite length.
Rays are lines that have one endpoint and the other end of the line extends infinitely with no endpoint.
Opposite rays are two rays that have a common endpoint that point in opposite directions and form a straight line.
My nephew, Oliver, got a new Lego set. He has decided to build it with his friend, Josie. It took them 6 hours to build together. If Oliver is half as fast as Josie, how long would it take Josie to build this Lego set alone?
Answers
Answer:
4 hours
Step-by-step explanation:
If it took them together with a total of 6 hours and Oliver is half as fast meaning Jose is faster it will take Jose 4 hours.
A simple equation is
6= 4+2
And the 2 would be Oliver since Oliver is half as fast.
