Total sum of angles in a triangle is 180
I'll do the first one, you can try the second
9x + 5 + 78 + 25 = 180
9x + 108 = 180

In a poll to pick the name of a new planet discovered in a distant solar system, a total of 963 scientists voted. There were four names to pick from. The winning name exceeded the other names by 53, 79, and 105 votes, respectively. How many scientists voted for the name which came fourth in the poll?
Answer:
195
Step-by-step explanation:
Let wining name have, x votes
1st = x
2nd = x - 53
3rd = x - 79
4th = x - 105
x + (x - 53) + (x - 79) + (x - 105) = 963
x + x - 53 + x - 79 + x - 105 = 963
4x - 237 = 963
4x = 963 + 237
4x = 1200
x = 1200 / 4
x = 300
4th = x - 105
x - 105 = 300 - 105 = 195

Find the distance between the pair of points. (4,1) and (9,6)
Answer:
5√2 or 7.07 units
Step-by-step explanation:
To find the distance between two points, we want to use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]
Plug in the given values of (4,1) and (9,6)
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(9 - 4)² + (6 - 1)²]
Simplify the parentheses.
d = √[(5)² + (5)²]
Simplify the exponents.
d = √[25 + 25]
Add.
d = √[50]
Evaluate the radical.
5√2 or 7.07
Round the decimal.
5√2 or 7.07 units

Given that ℓ1∥ℓ2 and the measure of ∠c = 44°, find the measures of angles a and b.
m∠a =
°
m∠b =
°
Answer:
<a = 44 degrees
<b = 136degrees
Step-by-step explanation:
From the given diagram;
<a = <c (alternate interior angle)
Since <c = 44 degrees, hence <a = 44 degrees
Also the sum of a and b is supplementary hence;
a + b = 180
44 + b = 180
b = 180 - 44
b = 136degrees
Hence m<b =136degrees
explain rounding up numbers i dont mean only examples but definitions too
Answer:
Rounding up numbers means to make a number with many numerical values or digits into a more simpler way.
Step-by-step explanation:
In order to round up a number you have to look to the digit next to it and if its greater then five it rounds up, if it's less then five it stays the same. If the number only has one digit then you have to look at that number and round up by seeing if its greater than or less than five.
Examples:
[tex]7[/tex]
[tex]7>5[/tex]
[tex]7=10[/tex]
7 rounded up equals 10 because 7 is more near 10 then it is to one.
Round the number 12,371 to the nearest thousand.
This means to find the thousands place value (two) check the number next to the thousands place value (hundreds or three) and check to see if that number is greater then five or not.
[tex]12,371[/tex]
[tex]3 <5[/tex]
[tex]=12,000[/tex]
Therefore the 12,371 rounded to the nearest thousand is "twelve-thousand" and that's because three is not greater then or equal to five.
Hope this helps.

Step-by-step explanation:
How many cubic meters of material are there in conical pile of dirt that has radius 9 meters and height 6 meters?Use 3.14 for pi
Answer:
V = 226.08 m³
Step-by-step explanation:
The formula for the volume of a cone of base radius r and height h is
V = (1/3)(πr²)(h).
In this case, r = 6 m and h = 6 m. Thus, the volume of this conical pile is
V = (1/3)(3.14)(6 m)²(6 m), or
V = 226.08 m³

mr. torres ordering 250 School t-shirts to sell in a school store the t-shirts come in blue gray or red to know how many of each color to order mr. torres polled a random sample of students l.the results are in the table
Answer:17
Step-by-step explanation:
so i think it would be 17 as 5 is equivlent to 8.33 percent of 60 which is the total amount of kids and 8.33 percent of 250 is 20 but since i think ur school rounds that percentage it would 17 red shirts
The results are in the table of the 250 total T-shirts about should be red 17.
We have given that,
Mr. torres ordered 250 School t-shirts to sell in a school store the t-shirts come in blue-gray or red to know how many of each color to order Mr. Torres polled a random sample of students. the results are in the table.
What is the random sample?
A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.
So I think it would be 17 as 5 is equivalent to 8.33 percent of 60 which is the total amount of kids and 8.33 percent of 250 is 20 but since I think your school grounds that percentage it would be 17 red shirts.

Which equation can be used to solve for c? Triangle A B C is shown. Angle A C B is 90 degrees and angle A B C is 35 degrees. The length of C B is 5 inches, the length of A C is b, and the length of B A is c.
Answer:
c = 5/Cos 35
Step-by-step explanation:
We are given the following
m<ACB = 90degrees
m<ABC = 35degrees
The side opposite to m<ABC is AC
BA = hypotenuse
CB = adjacent = 5inches
Required
Equation to solve BA which is c
Using the Pythagoras theorem;
Cos theta = Adjacent/Hypotenuse
Cos m<ABC = CB/BA
Cos m<ABC = 5/c
c = 5/cosm<ABC
c = 5/Cos 35
Hence the equation that can be used to solve for c is c = 5/Cos 35

A scientist has two solutions, which she has labeled Solution A and Solution Each contains salt. She knows that Solution A is 40% salt and Solution B is 55% salt. She wants to obtain 90 ounces of a mixture that is 45% salt. How many ounces of each solution should she use?
Our system of equations is given as
x + y = 90.... Equation 1
x = 90 - y
40% × x + 55% × y = 45% × 90 ounces
0.4x + 0.55y = 40.5....Equation 2
We substitute 90 - y for x in Equation 2

Given
Area = 8 1/4 square yards
width = 3
1/2 yards
Required
Length
Length = Area/width
Length = (8 1/4)/(3 1/2)
