Answer:
D. 9, 40, 41
Step-by-step explanation:
We can use Pythagorean theorem (a²+b²=c²) to answer this question by squaring the smallest 2 lengths then seeing if it equals the square of the 3rd length.
2²+3² = 4+9 = 13 ≠ 4²
12²+15² = 144+225 = 369 ≠ 20²
8²+9² = 64+81 = 145 ≠ 10²
9²+40² = 81+1600 = 1681 = 41²

If 3a+5=12, what is the value of 6a+14?
Answer:For example, choice A is incorrect because if the value of 10x + 3 were 4, then it would follow that x = 0.1, and the value of 5x + 6 would be 6.5, not 10.
Step-by-step explanation:
The answer is
283a + 5 = 12
subtract 5 from both sides
3a = 7
divide by 3 on both sides to isolate "a"
a = 7/3
Substitute 7/3 for "a" in the second equation
6(7/3) + 14
6 multiplied by 7/3 = 42/3 = 14
14 + 14 = 28

Which logarithmic equation is equivalent to 25 = 32? log232 = 5 log532 = 2 log325 = 2 log25 = 32.
Logarithmic function is the inverse of the exponential function. The logarithmic function that is equivalent to 2⁵ = 32 is log₂32=5.
What is the Logarithm function?A log function is a way to find how much a number must be raised in order to get the desired number.
[tex]a^c =b[/tex]
can be written as
[tex]\rm{log_ab=c[/tex]
where a is the base to which the power is to be raised,
b is the desired number that we want when power is to be raised,
c is the power that must be raised to a to get b.
Given to us
2⁵ = 32
As we know that we can convert a number powered to another number therefore exponential function into a log function, thus,
[tex]2^5 = 32\\\\\rm log_2 32 = 5[/tex]
Hence, the logarithmic function that is equivalent to 2⁵ = 32 is log₂32=5.

[tex] \\ [/tex]
Diameter sphere = 8mm[tex]\small \pi = 3.14[/tex][tex] \\ [/tex]
To find:-Volume of sphere[tex] \\ [/tex]
Solution:To find volume of sphere first we have to convert Diameter into radius .
Diameter = 2 radius
So:-
⇢Diameter = 2 radius
[tex]\\[/tex]

Bella needs 15 quarters of paint for one wall in her cellar she has 2 1/4 gallons left over from painting the other walls she has another 5 quarts that her neighbor gave her is that enough paint
0.0455 quarters of paints is not enough to paint the wall. she needs 15 quarters.
She needs 15 quarters of paint for one wall .
She has 2 1 / 4 gallons left over from painting the other walls and she also has another 5 quarts that her neighbour gave her.
Therefore,
Conversion of measurement units4 quarts = 1 gallon
5 quarts = 5 / 4 gallons
Then,
total gallon = 9 / 4 + 5 / 4 = 14 / 4 = 7 / 2 gallons
Therefore,
1 gallons = 0.01301053418982 quarters
7 / 2 gallons = ?
cross multiply
number of quarters = 3.5 × 0.01301053418982
number of quarters = 0.0455 quarters
Therefore, 0.0455 quarters of paints is not enough to paint the wall. she needs 15 quarters.

Find the sum of the first 8 terms of the following sequence. Round to the nearest hundredth if necessary 6,−4, 8/3
Step-by-step explanation:
with the introduction of fractions it is clear we are multiplying things to get the sequence.
that makes this a geometric sequence, meaning that every new term is created by multiplying the previous term by a certain constant number, the ratio r.
what do we have to multiply with the first term (6) to get -4 ?
6×r = -4
r = -4/6 = -2/3
to check we use the same factor with the second term and see, if we get the predefined third term :
-4 × -2/3 = 8/3
correct, perfect.
so,
a0 = 6
an = an-1 × -2/3 = a0 × (-2/3)^(n-1) = 6 × (-2/3)^(n-1)
for the sum of a finite number of terms of a geometric sequence the formula is :
Sn = a0×(r^n - 1) / (r - 1) if |r| > 1
Sn = a0×(1 - r^n) / (1 - r) if |r| < 1
Sn = a0×n if r = 1
in our case : |-2/3| = 2/3 < 1
S8 = 6×(1 - (-2/3)⁸) / (1 - (-2/3)) =
= 6×(1 - 256/6561) / (3/3 - -2/3) =
= 6×(6561/6561 - 256/6561) / (5/3) =
= 6×(6305/6561) × (3/5) = 2×(6305/2187) × (3/5) =
= 2×(1261/2187) × 3 = 2×(1261/729) =

How many kilograms is a rice packet that weighs 750 g?
(Please answer quick!)
Answer:
0.750 kg
Step-by-step explanation:
Hi there ,
As you know 1 kg = 1000g
So when we convert g to kg then we divide the given value of grams by 1000.
So in this case we have 750 grams, changing it we have :
[tex]\frac{750}{1000}[/tex]
Since there are 3 zeroes in 1000 we move the decimal point by 3 places to the left leaving the answer as : 0.750 kg or [tex]\frac{750}{1000}[/tex] kg

Joel borrowed 518,000 for 6 years at simple interest to purchase a vehicle. If Joel repaid a
total of $20,953.80, at what rate did he borrow the money?
Answer:
2.735%
Step-by-step explanation:
The amount due on principal P after t years at rate r is ...
A = P(1 +rt)
Filling in the given values, we can solve for r:
20,953.80 = 18000(1 +6r)
20953.80/18000 -1 = 6r = 0.1641
r = 0.1641/6 = 0.02735 = 2.735%
Joel's interest rate was 2.735%.

a pet company makes a small bag that holds 2 pounds of dog food. They want a large bag of 40 pounds. What factor will the surface area of the bag increase ?
Answer: 20
Step-by-step explanation:
You do 40➗2 which you would get 20.
Then you would round 20 to the nearest tenth, then you get 20.
Because if the number on the left/right is between 0 and 4, the whole number stays the same.
Note: 0-4 stays the same 5-9 higher number.
For example: Rounding 164 to the nearest tenth will become 160.

What is mean by Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Six cantaloupes are cut into 32 equal portions for a catering event.
Now,
Since, Six cantaloupes are cut into 32 equal portions.
Hence,
In each portion, the amount of cantaloupe = 32 ÷ 6
= 32 / 6
= 5.33
Therefore,
The amount of the cantaloupe in each portion will be;

questions 11, 14, 15 - an obtuse angle is an angle greater than 90° but less than 180°
question 12 - an acute angle is an angle that is less than 90°
question 13 - a right angle is exactly 90°
in question 14 the angle starts at 30° and ends at 140° so you subtract 30 from 140
