whats the formula for the surface area of a triangle?
Answers
Answer:
use the formula A = 1/2bh, where A = area, b = base, and h = height. Once you have the areas of all sides and faces, you simply add them together to get the surface area.

Step-by-step explanation:
the lowest temperature ever recorded on earth's surface was −128.5°f. the highest temperature was 262.5°f higher than the lowest.what was the highest temperature ever recorded?
Answers
Answer: 134 °f
Step-by-step explanation:
Lowest is -128.5 °f, the highest is 262.5 °f higher than the lowest.
you would simply add 262.5 °f to your -128.5 °f, giving you 134 °f.
another way of doing this is subtracting 128.5 from 262.6
Explanation :
So basically, make the degree 0 which means taking away 128.5 from the 262.5 and adding it to the negative number. You add 128.5 from -128.5 because when the number is in the negatives, adding makes it closer to positive. So now you’ve used 128.5 of that 262.5 which means subtract 128.5 from 262.5 which gives you 134 left. That 134 is going to be added to the 0 and (134 + 0 = 134°) so you’ll be left with 0 degrees higher and you’ll get 134° as your answer.
Mrs. Mason volunteers to make one prize ribbon for each of the forty-seven students who will attend math camp. Mrs. Mason will decorate each prize ribbon with sequins. Mrs. Mason buys packages of sequins. Each package holds one-fourth of a pound of sequins. Each package has enough sequins to decorate six prize ribbons. How many packages of sequins does Mrs. Mason need to buy to make the prize ribbons? How many pounds of sequins does Mrs. Mason have to buy to make the prize ribbons? What part of a pound of sequins will be used to make each prize ribbon? Show all your mathematical thinking.
Answers
Answer:
Step-by-step explanation:
First, we find out how many times 6 goes into 47 to know how many 1/4 of a pound sequin bags we need. 47 divided by 6 equals 7, with a remainder of 5. That means that we actually need 8 1/4 pounds of sequin. We then simplify, and we need 2 pounds of sequins. Wooh, that’s a lot!

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answers
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.
a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?
Answers
and
C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
Multiply these two combinations since the faculty members and students are selected independently:
Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045
Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:
C(7, 4) = 7! / (4!(7 - 4)!) = 35.
So, there are 35 ways to select 4 faculty members from the 7 eligible ones.
For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:
C(13, 5) = 13! / (5!(13 - 5)!) = 1287.
Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.
To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:
35 * 1287 = 44,895.
Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

the answer should be 19j-13k because first all remember when we are dealing with this expressions or problems we need to add or subtract like terms that for example it could be 2j and 17j and 11k and 2k.
2j-11k+17j-2k=
2j+17j= 19j -11k-2k= 13k so the answer is 19j-13k and remember this is the final answer because we cannot add numbers that have different variables or letters so hopefully that is the correct answer and have a great day.

What is the equation of the line that passes through the point (-3,7) and has a slope of -4/3
Answers
Answer:
y=-4/3+3
Step-by-step explanation:
To find this equation in slope-intercept form you must first put it into point-slope form. Remember point-slope is \(y-y_{2}=m(x-x_{2})\) so plugin the points and slope to get \(y-7=-4/3(x+3)\). Then solve the equation for y.
First, distribute the -4/3
y-7= -4/3x-4
Then, add 7 to both sides
y=-4/3+3
Answer:
y=-4/3x+3
Step-by-step explanation:
y-7=-4/3(x-(-3))
y-7=-4/3x-4
y=-4/3x+3

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

Answer:
x = 7.5, y = 8.5-----------------------------------
The two angles with the variable x form a linear pair and therefore:
16x - 18 + 10x + 3 = 18026x - 15 = 18026x = 195x = 195/26x = 7.5Angles 16x - 18 and 12y are congruent as vertical angles:
16*7.5 - 18 = 12y102 = 12yy = 102/12y = 8.5Answer:
x = 7.5
y = 8.5
Step-by-step explanation:
Linear Pair
Two adjacent angles that sum to 180° (two angles which when combined together form a straight line).
To find x, equate the sum of the two angles with the variable x to 180° and solve:
⇒ (16x - 18)° + (10x + 3)° = 180°
⇒ 16x - 18 + 10x + 3 = 180
⇒ 26x - 15 = 180
⇒ 26x = 195
⇒ x = 7.5
Vertical Angles Theorem
When two straight lines intersect, the opposite vertical angles are congruent.
Therefore:
⇒ (16x - 18)° = 12y°
Substitute the found value of x into the equation and solve for y:
⇒ 16x - 18 = 12y
⇒ 16(7.5) - 18 = 12y
⇒ 120 - 18 = 12y
⇒ 102 = 12y
⇒ y = 8.5
