Answer:
t = 1 1/4 hours
Step-by-step explanation:
Lets first make an equation to represent the situation. t + 1/2 = 1 3/4
Because we cant add fractions with different denominators we have to change 1/2 to 2/4.
Next, we need to isolate t. Subtract 2/4 from both sides of the equation to get 1 1/4.
t = 1 1/4.

What is the volume of the prism?
Answer:
4.5 ft
Step-by-step explanation:
Formula to find volume of the prism is :
Volume = Length × Width × Height
We know that,
[tex]1\frac{1}{2}[/tex] = 1.5
Let us solve now.
Volume = Length × Width × Height
= 2 ft × 1.5 ft × 1.5 ft
= 3 ft × 1.5 ft
= 4.5 ft
Esi says that the value of z when z^2 = 80 does not belong in either of these categories since z must be greater than 8.
What whole number would z be closest to?
(please explain)
Answer:
9
Step-by-step explanation:
if z=8 then z^2 would be 64, which is not equal to 80
iz z=9 then z^2 would be 81, which is closer to 80 than 64
therefore, 9 is the whole number than z would be closest to

Hii.
First, lets divide 1/9 by 5 .
1/9 divided by 5 is 1/45
Lets multiply to find out the answer.
1/9 x 5 =5/9.
So this is not correct since it does not equal 1/45
9/1 x 5/1 is 45
This is not correct because it does not equal 1/45
1/9 x 1/5 is 1/45
This is correct because it equals 1/45

Answer:
line 1: y= 1x+ 2
line 2: y= -1x-0.5
(usually 1 is omitted but I added for clarity)
Step-by-step explanation:
slope (x)= yfinal-yintial/xfinal-xinitial
b= where line intersects y axis
line 1: (-1,0), (0.5,1.5)
(1.5-0)/(0.5-(-1))
(1.5)/(1.5)
slope= 1x
y=x+ 2
line 2: (-0.5,0), (0.5,-1)
(-1-0)/(0.5-(-0.5))
(-1)/(1)
slope= -1x
y=-x-0.5

Jasper had a sports card album that held 100 cards. He filled 42/100 with football cards and 3/10 with baseball cards. What fraction of the album is still empty?
A. 28/100
B. 45/100
C. 55/100
D. 72/100
The fraction of the album that is still empty is 28/100, the correct option is A.
What is a fraction?A fraction represents a part of a number or any number of equal parts.
A fraction consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of proper fraction keeping the denominator same.
We are given that;
The fraction 42/100
Now,
To rewrite 3/10 with a denominator of 100, we need to multiply both the numerator and denominator by 10. This gives us:
3/10 = (3 × 10) / (10 × 10) = 30/100
Now, we can add the numerators of the fractions and write the sum over the common denominator.
42/100 + 30/100 = (42 + 30) / 100 = 72/100
Therefore, the total fraction of the album that is filled with football and baseball cards is 72/100.
we need to subtract the fraction that is filled from the whole fraction, which is 1 or 100/100. To subtract fractions, we need to have a common denominator, which we already have as 100. So, we can subtract the numerators of the fractions and write the difference over the common denominator.
100/100 - 72/100 = (100 - 72) / 100 = 28/100
Therefore, the fraction will be 28/100.

A triangle has perimeter 3a+11. One side is 2a and another side is 8. What is the third side?
Answer:
1a + 3
Step-by-step explanation:
What's the perimeter of a triangle?
❖ The perimeter of a triangle is the distance around a triangle, or the
sum of all its side lengths.
How does it apply here?
❖ In this case, we're given the perimeter of the triangle as 3a + 11. We
also have two dimensions of the triangle: 2a and 8. Now, we need to
find the third side. To find the third side, we subtract 2a + 8 from 3a +
11.
Solving
[tex](3a+11)-(2a+8)[/tex] [tex]3a+11-2a-8[/tex] [tex]1a+3[/tex]Now, let's check if 1a + 3, 2a, and 8 add up to 3a + 11.
[tex]1a + 3 + 2a + 8[/tex] [tex](1a+2a)+(3+8)[/tex] [tex]3a+11[/tex]Therefore, the answer is 1a + 3.

Step-by-step explanation:Technology: Many of the problems in this book require the use of technology (graphing
calculators, computer software, or tablet applications) in order to solve them. You are
encouraged to use technology to explore, and to formulate and test conjectures. Keep the
following guidelines in mind: write before you calculate, so that you will have a clear record
of what you have done; be wary of rounding mid-calculation; pay attention to the degree of
accuracy requested; and be prepared to explain your method to your classmates. If don’t
know how to perform a needed action, there are many resources available online. Also, if
you are asked to “graph y = (2x−3)/(x+1)”, for instance, the expectation is that, although
you might use a graphing tool to generate a picture of the curve, you should sketch that
picture in your notebook or on the board, with correctly scaled axes.

PLEASE HELP FAST!!! Denise measured a community college and made a scale drawing. In real life, a building at the college is 122 meters long. It is 183 centimeters long in the drawing. What scale did Denise use?
3 centimeters : how many meters
The scale that Denise used for a community college and made a scale drawing is 3 centimetres: 2 meters.
Given that;
Denise measured a community college and made a scale drawing.
Now, for the scale Denise used, set up a proportion using the measurements from the drawing and real life.
So, from the proportion:
3 centimetres (drawing): x meters (real life) = 183 centimetres (drawing): 122 meters (real life)
Using cross-multiplication, solve for x:
3 centimeters × 122 meters = 183 centimeters × x meters
366 centimeters meters = 183 centimeters x meters
Now divide both sides of the equation by 183 centimetres to isolate x:
366 centimetres meters / 183 centimetres = x meters
x = 2 meters
Therefore, the scale Denise used is 3 centimetres: 2 meters.
