Answer:
-5/6 (negative five divided by six. the fifth option)
Step-by-step explanation:
The numerator is the first number. The denominator is the second number. Sign has to be the same and only one negative to make the fraction negative.
6 to the second power−2(5+1+3) equals?
Answer:
306
Step-by-step explanation:
6² = 36
36 - 2 = 34
Since 5+1+3 is in parenthesis, it comes before multiplication (remember PEMDAS or Order of Operations)
5+1+3 = 9
34 x 9 = 306
Answer:
306
Step-by-step explanation:
6² = 36
36 - 2 = 34
Since 5+1+3 is in parenthesis, it comes before multiplication (remember PEMDAS or Order of Operations)
5+1+3 = 9
34 x 9 = 306

HELP ME I DONT UNDERSTAND
Answer:
B. He should focus on females because the ratio of females to males is 5:2.
Step-by-step explanation:
By looking at the graph, you can see that there are 25 females and 10 males. The ratio for this is 25:10, but we can simplify by dividing both sides by 5! 25/5=5, and 10/5=2, so the simplified ratio of 25:10 is 5:2. If you look at all of the answer choices, you really don't have to look at the words a lot; there's only one choice that includes the ratio 5:2. That choice is B, so B is the answer!
Hope this helps you out!! Have an amazing day o(*^▽^*)o

time, she decides to use this method at 5 P.M. in the evening. She
measures the length of the tree's shadow and finds it to be 48 feet
long this time. Then she holds a 12-inch ruler perpendicular to the
ground and finds that it casts a 24-inch shadow. How tall will she find
the tree?

Pls help me out, I need to know what value of x makes this equation true
equation: 6(2x – 11) + 15 = 3x + 12
I have already found the answer to this equation (x = 7) but I need to know what value of x makes the equation true.
(If it's 7, my brain just needs a break from stuff, I've been up since 4 in the morning)
Answer:
x = 7

12x - 66 + 15 = 3x +12
12x - 51 = 3x + 12
9x = 63
x = 7
How is energy involved in physical change??
Answer:during phase chages
Step-by-step explanation:
During phase changes, energy changes are usually involved. For example, when solid dry ice vaporizes (physical change), carbon dioxide molecules absorb energy. When liquid water becomes ice, energy is released. Remember that all chemical reactions involve a change in the bonds of the reactants

Part A: James bought a cake that weighs 3 and 1 over 4 pounds. How many ounces does the cake weigh? Show your work. (5 points)
[16 ounces = 1 pound]
Answer:
3 pound cake=48 ounces)4 pound cake=64 ounces
Step-by-step explanation:
[16 ounces = 1 pound]-so you got this
James bought a cake that weighed over 4 pounds.
And one that is 3 pounds,so you wanna multiply 16 x 3 and you get 48
So that leaves the 3 pound cake to be 48 ounces
Just like the first one,you wanna multiply 16 x 4 and you get 64
