Answer:
Hypotenuse= 180.7 cm
Step-by-step explanation:
Using Pythagoras' theorem:
a^2+b^2=c^2 (let c= Hypotenuse "H")
(136)^2 + (119)^2 = H^2
18496+14161 =H^2
H^2= 32657
Taking square root on both sides
[tex]\sqrt{H}[/tex]= [tex]\sqrt{32657}[/tex]
H=180.7

The sum of three consecutive odd integers is 17 less than four times the smallest integer. Find the integers.
Please help, thank you!
Answer:
23, 25, 27
Step-by-step explanation:
n + (n+2) + (n+4) = 4n - 17
3n + 6 = 4n - 17
3n - 4n = -17 - 6
-n = -23
n = 23
therefore,
23, 25, 27 are the 3 consecutive odd integers

The local shelfer
d of their dogs and cats in
preparation for the holidays. The sale
was $ 100 for a dog and $15 for a
cat. If the shelter earned $1,390 for
seling dl 19 of their animds, how many
dogs and cats were adopted?
d + c = 19
100d + 15c = 1390
we can simplify the second equation
20d + 3c = 278
now d + c = 19
c = 19 - d
3c = 57 - 3d
now plug into second equation
20d + 57 - 3d = 278
17d = 278 - 57
17d = 221
d = 221 / 17
d = 13
now we can plug this into the first equation
13 + c = 19
c = 19 - 13
c = 6
13 dogs were sold and 6 cats were sold

A number cube is rolled and a coin is flipped. What is the probability that a number greater than 2 is rolled and the coin lands on heads?
Answer:
1/3
Step-by-step explanation:
The probability that a number greater than 2 is rolled is 4/6 {2, 3, 4 and 6} The probability that the coin lands on heads is 1/2
You can multiply 1/2 and 4/6 to find out the total number of possible outcomes: 1/2 × 4/6 = 4/12. This can be simplified to 1/3.

Explain how to find the mean of a data set.
Answer:
to find the mean you must add all of the numbers in a data set together and then divide by how many numbers there are.
Answer:
give brainliest?
Step-by-step explanation:
the mean or average of a data set is found by adding all numbers in the data and then dividing by the number of values in the set.
For example, if you have 10 numbers, you add them up and divide by 10. This would give you the mean of the data.
Here's another example with the numbers: 9,8,22,7,7,8,17
First add the numbers up: 9+6+20+7+7+8+20+2+2 = 81 Then divide 81 by the total number of data points, 9, and you get 9.
Theerefore the mean is 9.

We know that,
[tex]V = \frac{1}{3} (a{}^{2} + ab + b{}^{2})h \\ [/tex]
Also,
[tex]l {}^{2} = h {}^{2} + (b - a) {}^{2} [/tex]
[tex]6{}^{2} = h {}^{2} + (9 - 5) {}^{2} [/tex]
[tex]36 = h {}^{2} +16[/tex]
[tex]h {}^{2} = 36 - 16[/tex]
[tex]h = \sqrt{20} [/tex]
[tex]h = 4.47[/tex]
Now , putting the value in the formula of volume
we get,
[tex]V = \frac{1}{3} (5{}^{2}+ 5 \times 9 + 9{}^{2})4.47 \\ [/tex]
[tex]V = \frac{1}{3} (25 + 5 \times 9 + 81)4.47 \\ [/tex]
[tex]V = \frac{1}{3} (25 + 45 + 81)4.47 \\ [/tex]
[tex]V = \frac{1}{3} \times 151 \times 4.47 \\ [/tex]
[tex]V = 224.99[/tex]
Hence, the volume of the given frustum is 224.99 cubic unit

(4×(4 + 3)) - 3 = (4×7) - 3 = 28 - 3 = 25
((7 - 5) ÷ 1/2) × 2 = (2 ÷ 1/2) × 2 = (2 × 2) × 2 = 4×2 = 8
(5.4 + 3) × (6 - 2) = 8.4 × 4 = 33.6
(9 ÷ 3 + 6) × 3 = (3 + 6) × 3 = 9×3 = 27
(4 + 3.2) × ((9 - 2) + 2.5) = 7.2 × (7 + 2.5) = 7.2 × 9.5 = 68.4
remember 2 things :
1. first priority for the sequence of operations is defined by brackets. second priority are multiplication and division (both are on the same level, and you can do them either way). and only third priority is addition and subtraction (they come last, and if you keep the "-" signs with the numbers, you can do them also in any sequence among each other : a - b = -b + a).
2. when you divide by a fraction, then this is the same as multiplying with the upside-down version of that fraction.
a / 1/b = a × b/1 = a × b

Which statement is NOT true?
Answer: C. is not correct because angle 2 and angle 5 are same side interior angles. Same side interior angles of parallel lines always add up to 180 degrees. Therefore, the only way angle 2 would be equal to angle 5 would be if they were both 90 degrees, which the two angles are not always right angles.

please help in math!!! i need help in both (a) and (b) !! brainliest to who answers both!!
Part A
Answers:
Number of terms = 2Type = BinomialVariables = p and qNumerical coefficients = 4 and 7Degree = 3-------------------------
Explanation:
The two terms are separated by a plus sign. Since we have two terms, we have a binomial.
bi = 2nomial = names or termsThe variables are p and q, acting as placeholders for unknown numbers.
The coefficients are the numbers to the left of the variables, which are the 4 and 7.
The degree of multivariable polynomials is found by adding up the exponents for each term, then picking the largest sum. In each case, we get a sum of 3 for each monomial. The degree of the entire polynomial is therefore 3.
==============================================
Part B
Answer: t^3 - 20t + 26
-------------------------
Explanation:
We have an expression of the form
(6t^3-3t+5) - x = (5t^3 + 17t - 21)
which rearranges to
-x = (5t^3 + 17t - 21) - (6t^3-3t+5)
-x = 5t^3 + 17t - 21 - 6t^3 + 3t - 5
-x = (5t^3 - 6t^3) + (17t+3t) + (-21-5)
-x = -t^3 + 20t - 26
x = -(-t^3 + 20t - 26)
x = t^3 - 20t + 26
