Answer:
C. [tex]\frac{1}{49}[/tex]
Step-by-step explanation:
When one puts a number to a negative exponent, such as;
[tex]a^{-b}[/tex]
One is essentially doing;
[tex]\frac{1}{a^{b}}[/tex]
Applying that knowledge;
[tex]7^{-2} \\= \frac{1}{7^{2}}\\= \frac{1}{49}[/tex]

solve for missing angle
Answers
Answer:
Angle 1 = 88 degrees
Angle 2 = 42 degrees
Angle 3 = 113 degrees
Step-by-step explanation:
Angle 2 is a vertical angle to the angle whose measure is 42 degrees. Therefore, they are congruent. (Angle 2 = 42 degrees)
The Interior Angle Sum states that the sum of all the angles inside of a triangle always add up to 180 degrees.
180- (50+42)
180-92
Angle 1 = 88 degrees
180- (42+25)
180-67
Angle 3 = 113 degrees

Mr Wilkinson invests £3000 at a compound interest rate of 2.2% per annum.
He wants his investment to earn more than £800 interest.
Work out the least time, in years, that it will take
Answers
Answer: 12.1 years
Step-by-step explanation:
youd find 2.2% of 3000 which is 66 and then divide 800 by 66 to see how many years it would take to make 800 interest and you get 12.1 years. 90% sure on that answer btw
5x + 2(11-1) = 30
Solve the equation/Explain each step
Answers
Answer:
x=2
Step-by-step explanation:
the picture above shows how to go through the equation. I used PEMDAS
Answer:
2.
Step-by-step explanation:
5x + 2(11-1) = 30
First, solve the ones inside the bracket:
11 - 1 = 10
Next, multiply the number inside the bracket by the number next to bracket:
2 × 10 = 20
The equation will now be:
5x + 20 = 30
Since 5x and 20 are not like terms, carry +20 over to the other side making it 30 - 20:
5x = 30 - 20
5x = 10
Now, divide both sides by the coefficient of x (5):
5x/5 = 10/5
x = 2
The answer to the equation is 2.
if the product of two number is 10 and the sum is 7 ,then the longest of the two number is
Answers
Answer:
5 units
Step-by-step explanation:
Step one:
Given data
Le the first number be x
and the second number be y
So
x*y= 10-----------------1
and
x+y= 7-----------------2
from eqn 1
x= 10/y
put x= 10/y in eqn 2
[tex]10/y+y= 7\\\\10/y= 7-y[/tex]
cross multiply we have
[tex]10=y(7-y)\\\\10=7y-y^2[/tex]
rearrange
[tex]y^2-7y+10=0[/tex]
the factors of the quadratic expression are
-5 and -2
[tex]y^2-5y-2y+10= 0\\\\y(y-5)-2(y-5) =0\\\\y-2=0\\\\y= 2\\\\y-5= 0\\\\y=5\\\\[/tex]
The longest side is 5 units
A crane lifts a pallet of concrete blocks 7ft from the back of a truck. The truck drives away and the crane lowers the pallet 11ft What is the final position of the pallet relative to where it started in the back of the truck?
Answers
Answer:
The position of the concrete relative to its initial position is 4ft behind its initial position
Step-by-step explanation:
Let us analyze the problem following the sequence of events.
First of all, the crane is initially 7 ft from the back of the truck.
Once the truck drives away, the crane lowers the concrete at 11 ft away from the back of the truck.
To get this distance relative to the initial position, we have to subtract the initial position from the final position of the concrete.
This will be
11ft - 7ft = 4 ft
The position of the concrete relative to its initial position is 4ft behind its initial position

Slope = 7
3. The last option because it is not a line.
4. The third option. x and y do not get multiplied in linear equations.
5. The last option.
the first one is y=x
the second one is y =-x
the third one is y=0x - 2
the last one is wrong because if x is - 1 or - 2 twice, it should still give the same vue for y.

Which one of the following does not describe Aaron Burr?
made unwise decisions
was wanted for murder in two states
led the Senate
had a law practice
a brilliant politician
Answers
Answer:
Aaron Burr wasn't a brilliant politician.
Step-by-step explanation:
Aaron Burr was an American politician and the third Vice President of the United States from 1801 to 1805. In 1800, he ran for the Democratic-Republicans with Thomas Jefferson. Jefferson was supposed to be president and Burr vice president, but the then presidential election rules gave Jefferson and Burr equal votes in the Electoral College, and the election was ultimately decided in the House of Representatives. There, it were Jefferson and Burr's political rivals, the Federalists, who made the difference. Alexander Hamilton, the leader of the Federalists, eventually urged his party to back Jefferson, which helped make Hamilton and Burr deadly rivals. Burr had to settle for vice president under Jefferson.
On July 11, 1804, Burr challenged Hamilton to a duel in which Burr would fire the deadly shot. Burr was charged with murder in two states, but never prosecuted. After a short flight south, Burr returned to Washington to serve his term as vice president.
After his term, Burr was suspected of involvement in a plot to create a separate republic in the then Southwestern US, headed by himself. For this he was arrested in 1807. He was tried for treason but was acquitted. After a stay abroad, Burr returned to New York in 1812 and resumed his career as a lawyer. He died in 1836 at the age of eighty and was buried in Princeton, New Jersey.

Answers
Answer:
[tex]\dfrac{5}{8}[/tex] butter was left after she was done baking.
Step-by-step explanation:
Robin had 7/8 pound of butter when she started baking a cake. She used 1/4 pound of butter while baking.
We need to find how much butter was left after she was done baking.
It can be calculated as follows,
Left =
[tex]=\dfrac{7}{8}-\dfrac{1}{4}\\\\=\dfrac{7}{8}-\dfrac{2}{8}\\\\=\dfrac{7-2}{8}\\\\=\dfrac{5}{8}[/tex]
Hence, [tex]\dfrac{5}{8}[/tex] butter was left after she was done baking

Answer:
Does this problem have a picture, I just need to make sure I am seeing everything correctly thanks!
Step-by-step explanation:
a. -4 and 4b + 4 = 4b
-4 and 4b + 4 = -4 + (4b + 4) = 4b + (4 - 4) = 4b + 0 = 4b
b. 3x and 1 - 3x = 1
3x and 1 - 3x = 3x + (1 - 3x) = 1 + (3x - 3x) = 1 + 0 = 1
