Answer:
6 1/10
Step-by-step explanation:
Add 4 1/2 and 1 3/5. To add that, you need to multiply the denominators and the numerators, in this case that equals 10. So then add the fractions first 5/10+ 6/10=11/10. Since that is an improper fraction, add +1 to the hole numbers, so you answer would be 6 1/10

HELP ME PLZ IM CRYING predict the number of catfish kathy will catch next week if she catches 54 fish
6 carp
8 bass
7 catfish
Answer:
18
Step-by-step explanation:
Take a breath :) . I've got your back.
If she caught 6 carp + 8 bass + 7 catfish, she caught 6 +8 +7 fish total = 21.
7 of 21 were catfish.
If she catches 54 fish instead of 21, (and we have to assume the ratio stays the same), how many will be catfish?
Ratios are 7:21 and x:54, but we'll write them as fractions:
7/21 = x/54
Then cross multiply:
21x = (54)(7)
21x = 378
divide both sides by 21
x = 18
If she catches 54 fish total, we predict she will catch 18 catfish.
---------------------------------------------
If we go back to the original 7/21, we can reduce that to 1/3. Then ask what is 1/3 of 54? 18.
The equation y= ax describes the graph of a line. If the value of a is negative,
the line:
A. goes down and to the left.
B. is vertical.
C. goes up and to the left.
D. is horizontal.
Answer:
Goes up and to the left
Step-by-step explanation:
If the value of a is negative, the line is going down and to the left.
What is the general equation of a straight line?The general equation of a straight line is -
y = mx + c
where -
{m} is the slope of the line.
{c} is the {y} - intercept.
Given is that the equation {y} = ax describes the graph of a line.
It is asked to find that if the value of {a} is negative, then what would be the orientation of the line.
The general equation of a straight line is -
y = mx + c
Here {m} denotes the unit rate. Unit rate is the rate at which the value of {y} changes per unit change in the value of {x}. So, we can write that the orientation of the line is going down and to the left.
Therefore, if the value of a is negative, the line is going down and to the left.

What is the volume of a hollow ball whose other radius is 200m and inner radius of
100m.
What is the mass if it is iron*
Answer:
The volume of the hollow ball will be equal to the difference between the volume of a sphere with the outer radius and the volume of a sphere with the inner radius.
Remember that the volume of a sphere of radius R is given by:
V = (4/3)*pi*R^3
where pi = 3.14
Then if R is the outer radius, and r is the inner radius, the volume of the hollow ball is:
V = (4/3)*pi*( R^3 - r^3)
In this case, we have:
R = 200m
r = 100m
Then the volume of the hollow ball is:
V = (4/3)*3.14*( (200m)^3 - (100m)^3)
V = 29,306,666.67 m^3
Now, if this hollow ball is made of iron, we want to find the mass.
Remember the relation:
Mass = Density*Volume.
We know that the density of the iron is:
D = 7300 kg/m^3
Then the mass of this hollow ball is:
M = (7300 kg/m^3)*(29,306,666.67 m^3) = 213,938,666,666.6 kg

Part AA particular man on the seat, then 2 men are out of 4:
4C2 = 4!/(4-2)!2! = 4*3*2/2*2 = 64 women out of 7:
7C4 = 7!/(7-4)!4! = 7*6*5*4!/3!4! = 35Total combinations:
6*35 = 210Part BOption 1. 2 men excluded
3 men out of 3 and 4 women out of 7
Total ways:
7C4 = 35 (as above)Option 2. 2 women are excluded
3 men out of 5 and 4 women out of 5

A billboard is 6 meters long . One centimeter is approximately 0 .39 inch . About how long is the billboard in inches? Round to the nearest whole inch. In.
Answer: 234 inches
Step-by-step explanation:
The billboard is 6 meters long and we are given the conversion factor for centimeters to inches.
To convert the length to inches therefore, convert the length from meters to centimeters first:
1 meter = 100 cm
6 meters would therefore be:
= 6 * 100
= 600 cm
1 cm = 0.39 inches so 600 cm is:
= 600 * 0.39
= 234 inches
The area of a circle is 161 in. What is the radius?
Answer:
Approximately 7.16 in
Step-by-step explanation:
Hi there!
Area of a circle equation: [tex]A=\pi r^2[/tex] where r is the radius
Plug in the given area 161 in.²
[tex]161=\pi r^2[/tex]
Divide both sides by π to isolate r²
[tex]\frac{161}{\pi} =\frac{\pi r^2}{\pi} \\\frac{161}{\pi} =r^2[/tex]
Take the square root of both sides to isolate r
[tex]=r^2\\\sqrt{\frac{161}{\pi}} =r\\7.16=r[/tex]
Therefore, the radius of the circle is approximately 7.16 in.

The stem-and-leaf plot shows the number of broken crayons in each crayon box at a preschool. What is the greatest number of broken crayons in a box? A 7 crayons B 47 crayons c 477 crayons d 1469 crayons
Answer:
47
Step-by-step explanation:
Values on a stem and leaf plot can be obtained by using the key :
Stem | leaf
With each value in the stem representing the first digit and the value in the leaf denoting the second digit.
The highest stem value here is 4 and the highest leaf value is 7.
Hence, the highest number of broken crayon is 47.
