Qual o raio de uma superfície esférica com 40 cm2 de área, em cm, aproximada às centésimas? Responde à seguinte questão, escrevendo apenas o valor numérico em algarismos
Responder:
1,78 cm
Explicación paso a paso:
El área de superficie total de la superficie esférica se expresa como;
T = 4πr² donde
r es el radio
Dado
TSA = 40 cm²
Sustituir
40 = 4πr²
r² = 40 / 4π
r² = 10 / π
r² = 10 / 3,14
r² = 3,185
r = √3,185
r = 1,78
por lo tanto, el radio de la esfera a la centésima más cercana es 1,78 cm

What is the volume of a sphere with radius 4?
Round to the nearest whole number.
Answer:
268.08
rounded number- 268
find the number in the whole number place, 8, and look one place to the right for the rounding digit on the right side of the decimal point, 0. round up if this number is greater than or equal to 5, and round down if it is less than 5.
formula for sphere volume- 4/3 (pie- 3.14) r^2
You deposit 600$ in a savings account.the account earns 10% simple interest per year
A. What is the interest after 10 years?
B.what is the balance after 10 years
Answer:
A) $600
B) $1200
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 10%/100 = 0.1 per year,
then, solving our equation
I = 600 × 0.1 × 10 = 600
I = $ 600.00
The simple interest accumulated
on a principal of $ 600.00
at a rate of 10% per year
for 10 years is $ 600.00.

if 9 out of 25 people are left-handed what percent are right-handed
Answer:
64%
Step-by-step explanation:
If 9 out of 25 people are left-handed
That means 25-9 = 16 people are right handed
or 16/25 are right handed
Multiply the top and bottom by 4 to get it out of 100
64/100
Percent means out of 100
64% are right handed

*5 EXTRA POINTS* The height of a cylinder is 8 units. The circumference of the base of the cylinder is 10π units.
Which measurement is closest to the volume of the cylinder in cubic units?
the answer would be 80 cubuc unitsStep-by-step explanation:
Answer:
628.32
Step-by-step explanation:
the circumference is ALWAYS Pi times more than the diameter so the diameter must be 10, and 10/2 is 5 so the radius is 5
5 squared is 25
25 times π is 78.5398163397
and 78.5398163397 times 8 is around 628.32

HELP ME JIM! Math HW
Problem 7
Answers:
dots A = 2dots B = 5-----------------------
Explanation:
In step 1, there are 2 dots. So that number (2) fills in the blank for dots A.
Step 2 has 5 dots, which fills in the blank for dots B.
===========================================================
Problem 8
Answer: A) Quadratic
-----------------------
Explanation:
We have this sequence of dots: {1, 2, 5, 10, ...}
Note the increments of +1, +3, +5, ...
The increments aren't the same, so we don't have a linear sequence. But because the increment amounts go up by 2 each time, this strongly implies a quadratic sequence.
The rule for this sequence is n^2 + 1. Whatever the step number (n) is, we square it and add 1 onto that result. For instance, for step 3, we have n = 3 that leads to n^2 + 1 = 3^2 + 1 = 9 + 1 = 10. Also, note how the lone dot on the left of step 3 is tacked onto the 3 by 3 square of dots.
===========================================================
Problem 9
Answers:
dots A = 3dots B = 9-----------------------
Explanation:
Same idea as problem 7
===========================================================
Problem 10
Answer: B) Exponential
-----------------------
Explanation:
The sequence is {1, 3, 9, 27, ...}
In step 3 we have 3 rows and 9 columns of dots to give 3*9 = 27 dots total here.
The sequence is growing by a factor of 3 each time. In other words, we are tripling the terms or multiplying each term by 3 to get the next term.
Therefore, we have an exponential pattern.
The rule is 3^n
Eg: if we're on step n = 2, then we have 3^n = 3^2 = 9 dots.

Mrs. Barkley is making a snack mix out of different flavors of pretzels and chips. The weight of each snack package she used to make the mix is shown on the line plot below. What is the total weight, in ounces, of the snack mix?
Answer:
20 ounces
Step-by-step explanation:
The line plot is attached below.
From the line plot, we can see that there is a total of 7 snack mix. Two of the snack mix weigh 1 and half (1.5) ounces each, one snack measure 2 and three quarter (2.75) ounce, three snack mix measure three and half (3.5) ounce each and one snack measure 3 and three quarter (3.75) ounce. Therefore the total weight of the snack mix is:
Total weight = (2 * 1.5) + (1 * 2.75) + (3 * 3.5) + (1 * 3.75)
Total weight = 20 ounces

a packet contains blue and yellow flower seeds in thwle ratio 3:4. there are 32 floweer seeds
Note: We need to find the number of seeds of each color.
Given:
A packet contains blue and yellow flower seeds in the ratio 3:4.
There are 32 flower seeds.
To find:
The number of blue and yellow flower seeds.
Solution:
Let the number of blue and yellow flower seeds are 3x and 4x respectively.
There are 32 flower seeds.
[tex]3x+4x=32[/tex]
[tex]7x=32[/tex]
[tex]x=\dfrac{32}{7}[/tex]
[tex]x\approx 4.57[/tex]
Now,
The number of blue flower seeds is
[tex]3(4.57)=13.71\approx 14[/tex]
The number of yellow flower seeds is
[tex]4(4.57)=18.28\approx 18[/tex]
We approx. the value rounded to the nearest integer because the number of flower seeds cannot be a decimal of fractional value.
Therefore, the number of blue seeds is 14 and the number of yellow seeds is 18.

Step-by-step explanation:
(x+8)(x-5)
[tex] (x + 8)(x - 5) [/tex]
Answer: [tex]\huge\boxed{\ x^2+3x-40}[/tex]
My step-by-step explanation:
1. First thing we do is: Distribute
(x+8)(x−5)x
(x−5)+8(x−5)
2. Second thing:Distribute
x(x−5)+8(x−5)
x^2−5x+8(x−5)
3.Third thing: Distribute
x^2−5x+8(x−5)
x^2−5x+8x−40
4. Fourth thing: Combine like terms
x^2−5x+8x−40
x^2+3x−40
5.And finnaly we find: The solution
x^2+3x−40
Good Luck!
