Can someone help me please? ill give brainliest. please help this is due soon :(
(sorry for the random spams)
Answer:
B & C
Step-by-step explanation:
Okay I don't know much you need explained so I'm gonna explain pretty much everything. Starting off, you need to follow the PEMDAS rules. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. So when solving you have to do it in this order.
A-(5)(0.6)*7=21
B-(4/5)(15)+8=(0.8)(15)+8=20
C-4(8+2)/2=4(10)/2=40/2=20
D-14+4(2+3)=14+4(5)=14+20=34
If you need any clarification just lmk :)

Which measurements could NOT represent the side lengths of a right triangle? A. 12 in, 35 in, 37 in B. 10 in, 24 in, 26 in C. 4 in, 6 in, 10 in D. 6 in, 8 in, 10 in
❗ The answer is C, since 6+4 is 10, which means that it is not a right triangle.
~ ₕₒₚₑ ₜₕᵢₛ ₕₑₗₚₛ! :₎ ♡~
Answer:
C
Step-by-step explanation:
Simple just order it because 6+4 is equal to 10 it automatically makes it a non right trisngle
what is the surface area?
Surface Area = 96

A = 96
Develop a probability model for the spinner shown.
Will give brainliest!
Answer:
Suppose we roll a six-sided number cube. Rolling a number cube is an example of an experiment, or an activity with an observable result. The numbers on the cube are possible results, or outcomes, of this experiment. The set of all possible outcomes of an experiment is called the sample space of the experiment. The sample space for this experiment is \displaystyle \left\{1,2,3,4,5,6\right\}{1,2,3,4,5,6}. An event is any subset of a sample space.
The likelihood of an event is known as probability. The probability of an event \displaystyle pp is a number that always satisfies \displaystyle 0\le p\le 10≤p≤1, where 0 indicates an impossible event and 1 indicates a certain event. A probability model is a mathematical description of an experiment listing all possible outcomes and their associated probabilities. For instance, if there is a 1% chance of winning a raffle and a 99% chance of losing the raffle, a probability model would look much like the table below.
Outcome Probability
Winning the raffle 1%
Losing the raffle 99%
The sum of the probabilities listed in a probability model must equal 1, or 100%.

Factor [tex]15x+ 40[/tex] Show what you're dividing each term by
Answer:
The answer is 5(3x + 8)
Step-by-step explanation:
Find the Greatest Common Factor (GCF).
[tex]gcf = 5[/tex]
Factor out the GCF.
[tex]5( \frac{15x}{5} + \frac{40}{5} )[/tex]
Simplify each term in parentheses.
[tex]5(3x + 8)[/tex]
hence, the answer will be 5(3x + 8).
