Hi :)
The volume of a sphere is
V = 4/3 (pi) r^3
Supposing "length" as diameter
We can take the radius
2.40/2
1.2 is the radius of the sphere.
Inserting the radius into the formula
V = 4/3 (pi) 1.2^3
The volume is aproximately 7.24cm^3

can also be written as
[tex]\frac{4}{1}[/tex] ÷ [tex]\frac{5}{7}[/tex]
[tex]\frac{4}{1}[/tex] ×[tex]\frac{7}{7}[/tex] [tex]\frac{5}{7}[/tex] × [tex]\frac{1}{1}[/tex] (to do the denominators same)

Pls help I’ll give you 35 points You toss a coin four
times. What is the
probability of getting
tails all four times?
Make a tree diagram
for tossing a coin
four times.
Answer:
.375 or 6/16
Step-by-step explanation:
When you flip a coin you have 50/50 chance for it to land on heads or tail, assuming its not weighted or a trick coin.
Do this 4 times and the chances are now slimmer due to the amount of times it was flipped. In this case the probability of of you getting tails every time if you flip the coin 4 times is now .375 chance or 6/16. Here's the link to my work in a tree diagram

An angle measuring 60 degrees is measured as 62 degrees. What is the percentage error correct to 3 significant figures?
Answer:
3.33%
Step-by-step explanation:
60 = theoretical/actual degree measure
62 = experimental/calculated degree measure
% error = (|actual - calculated|/actual)*100
In words, the absolute value of the actual value minus the calculated value is first calculated. Then, divide the difference by the actual value that you should have obtained. Since you want this converted to a percent, multiply the decimal value of your quotient by 100.
Three significant figures is 3.33 because none of these numbers are leading or trailing zeros. If you count how many numbers (that are not leading or trailing zeros) the value 3.33 has, you'll find 3 significant figures, which is why your final answer should be 3.33%.

Combine like terms
7x+2 = 2x+13
Subtract 2x from each side
7x+2-2x = 2x+13-2x
5x+2 = 13
Subtract 2 from each side
5x+2-2 = 13-2
5x = 11
Divide each side by 5
5x/5 = 11/5
x = 11/5
Answer:
2.2
Step-by-step explanation:
4x+2+3x=5+2x+8
combine like terms
7x+2=2x+13
Subtract 2x from each side
5x+2=13
subtract 2 from each side
5x=11
Divide each by five
x=2.2

1. How can you use addition to check
that 1.55 cm is the difference in the
wingspans of the two butterflies?
The check using addition, the value of difference is added to the smaller value which should give the larger wingspan value.
The value of the wingspan of the butterflies aren't given, however, we could take hypothetical values for the wingspan of the two butterflies :
Wingspan of Butterfly A = 5.55 cm
Wingspan of Butterfly B = 4 cm
This means that, the difference in the wingspan is :
Wingspan of A - Wingspan of B
5.55 cm - 4 cm = 1.55cm
To check using addition :
The value of the difference added to the value of the butterfly with the lower wingspan should give the value of the wingspan of butterfly B(larger wingspan).
This means:
4cm + 1.55cm = 5.55 cm
Hence, the value of the difference is correct.
