Answer:
The answer would be the first one, combining 8 and -2
Step-by-step explanation:
This is because the 2 like terms are 8x^2 and -2x^2. You can get this by looking in the problem. There are 2 terms with x^2 which means we have to combine them. One of them is 8x^2 (the 1st one) and the other is -2x^2 (since it says 7-2x^2)
If you combine these you will get 6x^2 [8+(-2)=6]

Jones covered a distance of 50 miles on his first trip. On a later trip he traveled 300 miles while going three times as fast. His new time compared with the old time was:
(a) three times as much, (b) twice as much, (c) the same, (d) half as much, (e) a third as much
please explain your thought process
Answer:
The answer is b. But you asked for the thought process so...
Step-by-step explanation:
Let speed of the 1st trip x miles / hr. and speed of the 2nd trip 3x / hr.
We know that
Speed = Distance/Time.
Or, Time = Distance/Speed.
So, the time taken to cover a distance of 50 miles on his first trip = 50/x hr.
And the time taken to cover a distance of 300 miles on his later trip = 300/3x hr.
= 100/x hr.
So we can clearly see that his new time compared with the old time was: twice as much.
Have a great day :)

Question 3 (1 point) Find the area of the figure. Round to the nearest hundreth. 44 in A= in2 Blank 1:
Answer:
50 in
Step-by-step explanation:
2) Mass of the earth is 5976000000000000000000000 kg and that of Uranus is 86800000000000000000000000 kg , which one has greater mass ? and how much ? compare in exponential form.
Step-by-step explanation:
mass of earth=5.976×10^24 and
mass of Uranus =8.68×10^25
the mass of
Uranus is greater than that of the Earth by comparing its power 10
The mass of Uranus is greater than that of the Earth by comparing its power 10
What is an exponential form of 10?It is a shortcut way of writing repeated multiplication involving base and exponents. For example the 3 in [tex]10^{3}[/tex] is called the exponent. The expression [tex]10^{3}[/tex] is called exponential expression.
Given
Mass of the earth = 5976000000000000000000000 kg
Rewrite in exponential form
Mass of the earth = 5.976×10^24
Mass of Uranus = 86800000000000000000000000 kg
Rewrite in exponential form
Mass of the Uranus = 8.68×10^25
∴ 8.68 × [tex]10^{25}[/tex] > 5.976 × [tex]10^{24}[/tex]
We can clearly say that by seeing the exponential form of masses of earth and Uranus i.e.,
The mass of Uranus is greater than that of the Earth by comparing its power 10.

solve for angle..........
Answer:
57
Step-by-step explanation:
An angle formed by a tangent and secant is equal to half the difference of its intercepted arcs. ( major arc minus minor arc to be more specific. )
∠B is the angle formed by a tangent and secant
Arc CA is its intercepted arc ( minor arc to be more specific )
Arc DA is also its intercepted arc ( major arc to be more specific )
Hence, ∠B = [tex]\frac{1}{2}[/tex] ( Arc DA - Arc CA )
If arc CA = 51 and Arc DA = 165
Then ∠B =
[tex]\frac{1}{2} (165-51)\\165 - 51=114\\\frac{1}{2} (114)=57[/tex]
Hence, ∠B = 57
Given that mDE = 49° and mFG = 12°, find mFE.
Answer:
mFE = 119°Explanation:
mGB = 90°
mGB = mBD
∴ mGD = 180°
⇒ mFE = 180 - (mDE + mFG)
mFE = 180 - (49 + 12)
mFE = 180 - 61
mFE = 119°
Answer:
119°
Step-by-step explanation:
[tex] In\: \odot A, [/tex] GD is diameter.
[tex] \therefore m\widehat{GFD} = 180\degree [/tex]
[tex] \because m\widehat {FG} +m\widehat {DE} = m\widehat {FE} \widehat{GFD} [/tex]
[tex] \therefore m\widehat {FG} +m\widehat {DE} + m\widehat {FE} = 180\degree [/tex]
[tex] \therefore 49\degree +12\degree + m\widehat {FE} = 180\degree [/tex]
[tex] \therefore 61\degree + m\widehat {FE} = 180\degree [/tex]
[tex] \therefore m\widehat {FE} = 180\degree - 61\degree [/tex]
[tex] \therefore m\widehat {FE} = 119\degree [/tex]

0.326 as a fraction
Answer:
163/500
Step-by-step explanation:
we will not only clearly explain how to get the answer to 0.326 as a fraction, but also prove to you that our answer is correct.
First, note that 1000 multiplied by .326 will get rid of the decimal point. Therefore, make a fraction where the numerator is .326 times 1000 and denominator is 1000 like this:
.326 x 1000
1000
Next, multiply the numbers in the numerator together and keep the denominator as is. Now our fraction looks like this:
326
1000
The greatest common factor of 326 and 1000 is 2, which means you can divide the numerator and denominator by 2 and keep the same value:
326 ÷ 2
1000 ÷ 2
And when calculating the numerator and denominator in our fraction above, we get .326 as a fraction in the simplest form possible:
.326 =

An article costing Gh37000 was sold for Gh31450. What is the loss percent
Answer:
15%
Step-by-step explanation:
The first step is to find the loss
Cost price -selling price
37000-31450
= 5,550
The loss percent can be calculated as follows
= loss/cost price × 100
= 5550/37000 × 100
= 0.15×100
= 15%
Hence the loss percent is 15%

H=(...-2,-10,1,2,...3what type of set is H
A : empty set
B: finite set
C: infinity set
D: universal set
Answer: Universal set
Step-by-step explanation:
A universal set is usually represented by U and it is set that has all the elements of a related sets.
For example, if there are two sets which are X and Y. Let's say X = {1,2,3} and Y = {1,a,b,c}, therefore, the universal set will be U = {1,2,3,a,b,c}.
In the above scenario, H(...-2,-10,1,2,...3) is a Universal set.

Write the slope intercept form of the equation for a line passing through (-3,-1) and
(0,4)
Answer:
y = 5/3x + 4
Step-by-step explanation:
First, you need to find the slope. Use the slope formula of (y^2-y^1) / (x^2 - x^1).
Plug the numbers in.
(4 - (-1)) / (0 - (-3))
5 / 3
Slope is 5/3
Now, you have an equation of y = 5/3x + b.
Since one of the points shows you what y equals when x=0, that is your y intercept.
