Answer:
Adding the exponents
Step-by-step explanation:
Multiplying exponential terms with the same base
To multiply exponents with same base , we use exponential property
[tex]a^m \cdot a^m=a^{m+n}[/tex]
When we multiply exponents with same base then we add the exponents
So, adding the exponents best explains to simplify the expression that has same base with exponents .

Answer:
Table A, Table C, Table B
Step-by-step explanation:
f(x) = -4x - (-5)
f(0) = -4(0) - (-5) = 5
Table A
f(x) = -4x - (-1/5)
f(0) = -4(0) - (-1/5) = 1/5
Table C
f(x) = 4x + (2/5)
f(0) = 4(0) + (2/5) = 2/5
Table B

Which graph best represents the solution to the system of equations shown below? (5 points)
y = −2x + 14
y = 2x + 2
Answer:
The second graph
Step-by-step explanation:
take x = 3 for instance, we can see that on the graph both lines intersect on y = 8
if we try it with our equations:
-2 * 3 + 14 = 8
2 * 3 + 2 = 8
Hope thi helps, please give brainliest thanks
Explain why the triangles are similar and solve x and y
Answer:
x = 24
y = 26
Step-by-step explanation:
The triangle are similar because,
Each corresponding angles in the triangles are equal (AAA).
From the diagram,
5/10 = 12/x
Solving for x
x = (10×12)/5
x = 24
Also applying pythagoras theorem to get the hypotenuse of the larger side in the biggerr triangle.
y² = √(10²+24²)
a = √(100+576)
a = √(676)
a = 26.
Q4. Renna went on a journey that took 712 hours. The journey started at 22 48 on Monday. At what time and day did the journey finish?
Answer:
14:48 on wednesday
Step-by-step explanation:
divide 712 by 24 to get the total number of days. you should get 29.66666667. remember that 1/3 of a day is 8 hours, so you would have 16 hours left. you can subtract 2 hours from the 16 to add to the 22:48 to get it on an 12-hour period, which in this case would be midnight, and when you do this you need to add another day to the 29 you have. then you put the remaining 14 to the 00:48, giving you 14:48. to get the day she finished on, you should honestly do it on your fingers, counting out the days until you hit the 30th day, which should give you wednesday.

An isosceles triangle has an angle that measures 26°. Which other angles could be in that
isosceles triangle? Choose all that apply.
Answer:
26° 26° 128°
77° 77° 26°
Step-by-step explanation:
So we have two scenarios here.
One of them is if the base angles are 26°.
If that's true, the other angle is 128°
The other scenario is the opposite.
This means the base angles are 77°
John worked out the problem below but got the wrong answer:
X + 18 < 22

help please give me the answer and no links please
Answer:
x= 69°
Step-by-step explanation:
First find the inner angle of the 159°
so you would do 180-159=21
next you add 21 ° to the 90° from the right angle
that gives you 111°
last you do 180-111 and you get 69
Answer:
x = 69
Step-by-step explanation:
180 - 159 = 21
The sum of the three angles of any triangle is equal to 180 degrees, so:
21 + 90 + x = 180
111 + x = 180
180 - 111 = x
x = 69
Have a nice day!

Step-by-step explanation:
Answer:
-21 i think
Step-by-step explanation:
Between -10 and -16 has to be -13, because -13 is three apart from -10, and three apart from -16. That means that the numbers decrease by 3. So, the number line would be:
-10
-13
-16
-19
-21

Please, quickly. Sorry for the poor picture quality.
Answer:
<2 is 50º
Step-by-step explanation:
you first want to find what x is, so you would put the two equations in an (equation)=(equation) and get x and the number across from each other, that would be x=15º. you then plug in the 15 to the equation, and solve that, resulting in 130º. The angle is going to be 180 in total, so subtract the 130º from 180º and you would get 50º

Donald has xxx twenty-dollar bills and 111 ten-dollar bill. How much money does Donald have? Write your answer as an expression.
Answer:
20x + 10
Step-by-step explanation:
Given that :
Number of $20 bill = x
Number of $10 bill = 1
Total amount of money can be expressed as :
Σ(Value of bill * number of bill)
Hence,
($20 * x) + ($10 * 1)
20x + 10
The expression for the amount of money Donald has is : 20x + 10
The height of the apple trees in an orchard are normally distributed with a mean of 12.5 feet and a standard deviation of 1.2 feet what percentage of the apple trees are taller than 14.9 ft
Answer:
2.275%
Step-by-step explanation:
z = (x-μ)/σ, where
x is the raw score = 14.9 ft
μ is the population mean = 12.5 ft
σ is the population standard deviation = 1.2 ft
We are to find the percentage of the apple trees are taller than 14.9 ft,
This means x > 14.9, x greater than 14.9
Hence,
z = (14.9 - 12.5)/1.2
z = 2
Probability value from Z-Table:
P(x<14.9) = 0.97725
P(x>14.9) = 1 - P(x<14.9) = 0.02275
Converting to Percentage
= 0.02275 × 100
= 2.275%
Therefore, the percentage of the apple trees that are taller than 14.9 ft is 2.275%

There are 10 marbles in a bag .2 red, 5 green and 3 blue. Aron picks up 2 marbles without
replacing the first marble. What is the probability that both the marbles are blue.
Answer:
It would be 0.09
Step-by-step explanation:
First, note the original Probability for picking a blue marble in the first try:
0.3
Now, if this were to happen again, knowing that no marbles would be taken out, it would be another chance of 0.3 for Aron to pick up a blue marble on his second pick up.
Due to these being independent events, you can do:
0.3*0.3 = 0.09
To get your answer, 0.09.
Answer:
27/90 = 3/10
Step-by-step explanation:
Calculate the probability that neither is blue
7/10 * 6 / 9
63/90
Now the remainder of the choices are what the probability is when both are blue
1 - 63 / 90
27/90 is the probability of choosing 2 blues.

using three pieces of matchsticks form polygon a.hiw many sides does it have? b.how many vertices does it have? c.how many interior angles does it have?
Answers:
a) 3 sidesb) 3 verticesc) 3 interior angles===============================================
Explanation:
3 is the magic number here, and this applies to any triangle of any shape.
Each matchstick is one side of the triangle. Having three of them forms the three sides. When you intersect any pair of sides, you form a vertex which is a corner point of the triangle. Each vertex corresponds directly to an interior angle.
Side note: the 3 interior angles of any triangle always add to 180 degrees.

What does the remainder need to be in order for a x-value to be a zero (or factor) of a polynomial.
Answer:
Zero
Step-by-step explanation:
Remainder a x-value being a factor of a polynomial:
If a x-value [tex]x_v[/tex] is a factor of a polynomial, the remainder of the division of the polynomial by [tex]x - x_v[/tex] must be zero.
So the answer is Zero.
A package of 10 cans of soup costs $14. An individual can costs $2. You need at least 25 cans. Find the price of each combination of items.
Step-by-step explanation:
Since each package of 10cans costs $14
25cans would be 2 packages + 5 (since a package has 10)
So
14$ x 2 + 2$ x 5
=38$.
Mr. Wiliams brought a ice chest filled with water bottles to band practice. A model of the ice chest is shown below. What is the volume, cubic inches, of the ice chest?
Answer:
10,260 in³
Step-by-step explanation:
Please find attached an image of the chest
The ice chest is shaped like a rectangle. Thus the formula for the volume of a cuboid can be used to determine the volume of the chest
volume of a cuboid = length x width x height
18 in x 19 in x 30 in = 10,260 in³
