Step-by-step explanation:
2x(5+4)=(_x5)+(_x4)
lets start with 2x(5+4)
(5+4)=9
so we are left with 2x9
2x9=18
so now we have 18=(_x5)+(_x4)
lets try 2 for the blank spaces
18=(2x5)+(2x4)
2x5=10
2x4=8
10+8=18
2x(5+4)=(2x5)+(2x4)
It worked! Hope this helps :)
Answer:
Both blanks equal 2.

2*4=8
10+8=18
9*2=18

f(g(0)) given f(x)=3x-4 and g(x)=2x+7
Answers
Answer: First we evaluate g(0), then plug the value into f(x).
g(0) = -2(0) + 7 = 7.
Thus, we need to do f(7).
f(7) = 3(7)-4 = 21 - 4 = 17.

Triangle QRS has coordinates Q(–12,10), R(–8,8), S(–1,9). Give the coordinates of each vertex of the image after triangle QRS is dilated by a scale factor of 2.
Q’( , ) R’( , ) S’( , ).
Answers
Answer:
Q' = (-24, 20), R' = (-16, 16), and S' = (-2, 18).
Step-by-step explanation:
Recall that if a figure is dilated by a scale factor k (about the origin), then its coordinates become:
[tex](x, y) \rightarrow (kx, ky)[/tex]
In other words, we simply multiply each coordinate by the scale factor.
Triangle QRS with coordinates Q(-12, 10), R(-8, 8), and S(-1, 9) is dilated by a scale factor of two.
And we want to determine the coordinates of Triangle Q'R'S'.
Multiply each coordinate by the scale factor (two). Hence:
Q' = (-24, 20),
R' = (-16, 16), and
S' = (-2, 18).
Note: This method is only true when the figure is dilated about the origin.
Your car can drive 380 miles on a tank of 22 gallons.
a. How far can it drive on 50 gallons? Round your answer to the nearest
hundredth.
b. How many gallons are needed to drive 650 miles? Round your answer to the
nearest hundredth.
Answers
Answer:
a) 863.6miles b) 37.6 gallons
Step-by-step explanation:
1) 380/22=17.27- miles can be driven due to 1 gallon
a) 380/22*50=863.6
b)650/380/22=37.6
The car will go 863.63 miles, and the number of gallons 37.63 that will be needed to drive 650 miles.
What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
It is given that:
Your car can drive 380 miles on a tank of 22 gallons.
To find how far the car will go:
= 380/22
= 17.27
= (380/22)x50
= 863.63 miles
= (650/380)x22
= 37.63 gallons
Thus, the car will go 863.63 miles, and the number of gallons 37.63 that will be needed to drive 650 miles.

The hypotenuse of a right triangle measures 14 cm and one of its legs measures 6 cm.
Find the measure of the other leg. If necessary, round to the nearest tenth.
Answers
Explanation: if you use the Pythagorean theorem: a^2+ b^2 = c2, you would plug in 14 for c and 6 for a. Giving you
6^2+b^2=14^2
Simplify this and you would get:
36 + b^2 = 196
Subtract 36 from both sides getting you:
B^2= 160
Take the square root of both sides getting you your final answer of:
B= 40.
Mr. and Mrs. Ozawa are driving their family to a vacation spot 496 miles away. They want to get there in 8 hours.
Answers
Answer:
62 miles per hour
The average speed is 62 miles per hour.
What is Average speed?Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
Given that Mr. and Mrs. Ozawa are driving their family to a vacation spot 496 miles away. They want to get there in 8 hours.
We have to determine the average speed.
Here, we have the total distance traveled by a body = 496 miles
And the total time taken for the body to reach its destination = 8 hours
So, the average speed = distance / time
The average speed = 496/8
The average speed = 62 miles per hour
Hence, the average speed is 62 miles per hour.

Blue light has a wavelength of 4.75x10-7meters. What is this in standard form? A) 0.000000475 m B) 0.00000475 m C) 0.0000475 m D) 0.000475 m
Answers
Taking into account the definition of Scientific notation, the correct answer is the option A) 4.75×10⁻⁷ meters is written as 0.000000475 meters in standard form.
Scientific notationScientific notation is a quick way to represent a number using powers of base 10. This notation is used to be able to express very large or very small numbers very easily.
The numbers are written as a product:
a×10ⁿ
where:
a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.n = a whole number, which is called an exponent or an order of magnitude. Represents the number of times the point decimal is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.4.75×10⁻⁷ meters in standard formIn this case, to write the number 4.75×10⁻⁷ in standard form, the following steps are performed:
To write a number in standard form, you move the decimal point the same number of places as the exponent:
If the exponent is positive, you move the decimal point to the right. If the exponent is negative, you move the decimal point to the left.So, 4.75×10⁻⁷ is written as 0.000000475 in standard form.
In summary, the correct answer is the option A) 4.75×10⁻⁷ meters is written as 0.000000475 meters in standard form.
