Hope this still helps! :)
This is how you do it I’m pretty sure we are doin the same thing in my class
1)b.48 2)d.81 3)a.11 4)b.–81 5)–246 c.5ft a.19 9/25 in² d.11 mi/h a.48 C.a=m–c/–b
4r²–2s³ (r=1 s=5)
A=½bh. ½b=A/h. b=2A/h
area of a square=s×s=
d=rt then r=d/t
then r=15.4÷1.4=11 mi/h
(–h–3j)²/h (h=3, j=–5)
m=c–ab m–c=–ab m–c/–b=a
11 is B
14 B (4^-2= 1/(4^2))
These ones aren't hard. Add the exponents if it's multiplying, subtract if it's dividing.
The rest, multiply the numbers and add the exponents, then adjust for added digits.
but then adjust for sci not: 1.61*10^8
Move the decimal left one, add one to 10's exponent.

Step 1: Define
10s + -2s
Step 2: SimplifyRewrite: 10s - 2sCombine like terms: 8s
Expression can be broken down into a couple of parts.A term (like 10s, or -2s)The variable (what the unknown value is being represented by, in this case, s)The coefficient (the number next to the variable, showing what to multiply the variable by - in this case, 10 and -2)
When we have multiple terms with the same variable, we can perform operations on them assuming they have the same variable - for example, 5x + 6x = 11x, as 5+6=11.
We can apply the same logic here, however, note that adding a negative is the same as subtracting a positive. For example, 5 + -2 is the same as 5-2.
Therefore, our final expression is .
Hope this helped!
comment if you want the explanation, but you said you wanted it fast and it would take me like 10 minutes to right it all out
answer: the answer is (b) amie should have multiplied
step-by-step explanation: given a sphere and a cylinder with same radius and height.
let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,
r = h.
now, the volume of the sphere will be
and the volume of the cylinder will be
therefore, we have
thus, ammie should have multiplied the volume of the sphere
