Answer:
5.4×10^-1
Step-by-step explanation:
An adjustment in the exponent is needed to get to scientific notation at the end.
(9×10^5)(6×10^-7) = (0.9×10^6)(6×10^-7) = (0.9×6)×10^(6-7)
= 5.4×10^-1
_____
The applicable rule of exponents is ...
(a^b)(a^c) = a^(b+c)
_____
Of course, it can be useful to understand how moving the decimal point changes the exponent:
9 = 0.9×10 = 0.9×10^1

Answer: D
Step-by-step explanation:
When two triangles are listed as congruent, their corresponding angles are congruent, so when you have triangle EFG and triangle STU are congruent, it the angles E and S are congruent, F and T are congruent, and G and U are congruent, so the answer would be D.

A lasagna recipe calls for 1/4
a cup of sauce
for the bottom layer and 4/5
a cup of sauce for the top layer. How much sauce will you need to make the lasagna?
Answer: 17/20 sauce
Step-by-step explanation: First you would multiply 1/4 by 1/5 because of 4/5. Now we have 1/20. Then you would multiply 4 in 4/5 by 4 and 5 by 4. Then you would get 16/20. Then you would add them, 1/20 + 16/20 = 17/20 total sauce
3.On Monday morning, there were 30 cats and 45 dogs at an animal shelter. By the end of the week, 6 of the cats and 18 of the dogs had been adopted. What percentage of the animals were adopted?
Answer:
32%
Step-by-step explanation:
If on Monday, there were 30 cats and 45 dogs at an animal shelter, the total number of animal there will be 30+45 = 75animals
If by the end of the week, 6 of the cats and 18 of the dogs had been adopted, then the total number of animals adopted is 6+18 = 24animals
Percentage of animal adopted = Total adopted/total animals × 100%
Percentage of animal adopted = 24/75×100%
Percentage of animal adopted = 2400/75
Percentage of animal adopted = 32%
Hence 32% of the animals were adopted

Triangle Mid segment Theorem
Answer:
Hope this helps!!
Step-by-step explanation:
F:(-1,-4)
E:(-2,0)
D:(-2,-5)
The Midsegment Theorem states that the midsegment connecting the midpoints of two sides of a triangle is parallel to the third side of the triangle, and the length of this midsegment is half the length of the third side.

Geometry question plz help me!
Answer:
Step-by-step explanation:
Any linear equation can be written as y = mx + b
The point will determine b
The slope (m) is found by this formula for a perpendicular line
m1 * m2 = - 1
m1 = -1/m2
m1 = -1/(-2/3)
m1 = 3/2
So our equation looks like
y = 3/2 x + b
Now we use the point (4,-8)
-8 = 3/2 (4) + b
-8 = 3(2) + b
-8 = 6 + b
b = - 14
The answer is
y = 4/2 - 14

Are the lines parallel, perpendicular, or neither?
3x-y=5 y=3x+1
Answer:
Parallel
Step-by-step explanation:
To be parallel it would have to be the exact same slope, perpendicular would be the opposite...these equations have the same slope so it is parallel.

If Allies parents are willing to spend $300 for her party, how many people can attend? Show your work.
Answer:
17
Step-by-step explanation:
Since C represents the cost, and Allie's parents are willing to spend $300 for the party, our equation will now look like this:
300=5p+215
we are trying to find out how many people will able to attend
300=5p+215
-215 -215
---------------------
85 = 5p
divide by 5 on both sides to undo the multiplication (5p)
300=5p+215
-215 -215
---------------------
85 = 5p
÷5 = ÷5
--------------
17 = p
So, p (number of people attending) would be 17 :)
hope this helps!

Got it correct on quiz/
Answer:
x = 11, ∠ B = 71°
Step-by-step explanation:
In a parallelogram, consecutive angles are supplementary, that is
∠ A + ∠ B = 180°, thus
8x + 21 + 5x + 16 = 180
13x + 37 = 180 ( subtract 37 from both sides )
13x = 143 ( divide both sides by 13 )
x = 11
Thus
∠ B = 5x + 16 = 5(11) + 16 = 55 + 16 = 71°
A pitcher throws 152g baseball at a velocity of 30 m/s how much kinetic energy does the ball have?
Answer:
KE = 68.4J
The formula for Kinetic Energy is
KE = 1/2mv^2
m = mass (kg)
v = velocity (m/s)
152 grams to kilograms is 19/125kg
m=19/125
v=30
KE = 19/125 x 30^2
= 342/5
= 68.4
KE = 68.4J
