Step-by-step explanation:
u/4 + 9.9 = 16.9
Putting value of u = 24 in the equation
24/4 + 9.9 = 16.9
6 + 9.9 = 16.9
15.9 = 16.9
Bringing like terms on one
16.9 - 15.9 = 1

A middle school band uses a company to manage its fundraisers. The company charges a fee of $260 per fundraiser for its services. For the first fundraiser of the year, the band is selling insulated cups with school logos on them for $10.50 each. The goal of the fundraiser is to raise at least $1000.00. The following inequality represents this situation, where c stands for the number of cups

Answer:
Step-by-step explanation:
10.5c>or equal to 1260
Answer:
I don't see any inequality or a question.
Step-by-step explanation:
I suspect you want to know the minumum number of cups to sell in order to raise $1000 and pay off the company its $260
c(10.5) - 260 > 1000
c > (1000 + 260) /10.5
c > 120 cups

Henry has three metal rods. The three metal rods measure 7 feet, 9 feet, and 2 feet.
Based on the length of each rod, can Henry form a triangle with the three metal rods?
Complete the sentence by selecting the correct answers from the drop-down menus.
Answers
Answer:
No, Henry cannot form a triangle.
Step-by-step explanation:
The Triangle Inequality Theorem states that the sum of the lengths of two sides must be greater than the third side.
7 (first side) + 2 (second side) = 9
The sum of these two sides is not greater than the third side (9).
So, therefore, Henry cannot form a triangle.

What are the mean, median, mode, and range of the data set given the altitude of lakes in feet
-11, -28, -17,-25, -28, -39, 6, and -46?
mean = -25, median=-26.5, mode=-28; range = 40
mean=-25, median=-40, mode=-26.5, range=28
mean = -26.5, median =-25; mode=-28, range = 28
O mean = -26.5, median = -28, mode =-25; range = 40
Answers
Answer:
Mean (Average) = -23.5
Median = -26.5
Mode = -28
Range = 52
Step-by-step explanation:
Mean is found when adding all numbers and dividing the outcome by the number of numbers, so -
-11 + -28 + -17 + -25 + -28 + -39 + 6 + -46 = -188
-188 ÷ 8 = -23.5
Median is found in the center, and can be found ordered from least to greatest -
-46, -39, -28, -28, -25, -17, -11, 6
last 2 remaining number would be -28 and -25, add those and divide by 2 which gives you -26.5.
The Median would be -26.5
Mode is the number that has repeated itself the most.
-28 repeated itself the most.
The Range is found when the least number is subtracted by the greatest number so -
6 - (-46) = 52
