plz mark as brainliest
Can someone do this please
Answer:
124 degrees
Step-by-step explanation:
We know that a straight line is equal to 180 degrees. Therefore, all of these angles combined have to be equal to 180 degrees. This means the equation will be 3x+94+x+30+2x-4=180. Combine like terms to get 6x+120=180. 6x=60. x=10. Now that we know x, we plug it into the equation to find angle AOC. This will make the equation 3(10)+94. This is equal to 30+94 which is equal to 124. Therefore, angle AOC is equal to 124 degrees.

Two shops, waitrose and budgens sell the same brand of cans of soup but with different offers. Calculate the price for 18 tins at each shop. 6 for £4.25 9 for £6.14
Answer:
Waitrose: £12.75
Budgens: £12.28.
Step-by-step explanation:
The price of 6 tin cans in waitrose is £4.25
The price of 9 tin cans in budgens is £6.14
The price of one tin can in waitrose is
[tex]\dfrac{4.25}{6}[/tex]
The price of 18 tin cans in waitrose will be
[tex]\dfrac{4.25}{6}\times 18=\pounds 12.75[/tex]
The price of one tin can in budgens is
[tex]\dfrac{6.14}{9}[/tex]
The price of 18 tin cans in budgens will be
[tex]\dfrac{6.14}{9}\times 18=\pounds12.28[/tex]
The price of 18 tin cans in waitrose is £12.75 and in budgens is £12.28.

Select the correct answer from each drop-down menu. Javier purchased a digital camera for $384. The value of the camera depreciates by 25% every year. This situation represents . The rate of growth or decay, r, is equal to . So the value of the camera each year is times the value in the previous year. It will take years for the value of the camera to reach $162.
Answer:
it will take 3 yrs for the value of camera to reach $162.
Step-by-step explanation:
Pd = P(1-R/100)^T
162 = 384(1-25/100)^T
162/384 = (3/4)^T
27/64 = (3/4)^T
(3/4)^3 = (3/4)^T
T = 3
Answer:
this represents: exopnential decay, the rate of growth or decay is equal to: 0.25, value of the camera each year is: 0.75, it will take 3 years.

Roberto delivers 252 newspapers each morning. This morning, he has already delivered 197. He subtracts to find that he has 55 left to deliver today.
252 minus 197 = 55. 2 in the hundreds column is crossed out and 1 is above it. 5 in the tens column is crossed out and 14 is above it. 2 in the ones column is crossed out and 12 is above it.
Which equations can he use to verify his calculation? Check all that apply.
197 + 55 = 252
197 – 55 = 142
252 – 55 = 197
252 + 197 = 449
55 + 55 = 110
A. 197 + 55 = 252

If using the method of completing the square to solve the quadratic equation x^2+11x-38=0 which number would have to be added to "complete the square"?
Answer:
121/4
Step-by-step explanation:
To complete the square, we have to work with the coefficient of x
We have to divide the coefficient of x by 2, square it and add it to both sides
So we divide 11 by 2; which is 11/2; then square it
we have this as 121/4
This number is what we are going to have added
Answer:
You need to add [tex]\dfrac{121}4[/tex]Step-by-step explanation:
[tex]x^2+11x-38=0\\\\x^2+2\cdot\frac{11}2x-38=0\\\\\underline{x^2+2\cdot x\cdot\frac{11}2+\bold{\big(\frac{11}2\big)^2}}-\big(\frac{11}2\big)^2-38=0\qquad\qquad\qquad\{\big(\frac{11}2\big)^2=\frac{121}4\}\\\\ \big(x+\frac{11}2\big)^2-\frac{121}4-\frac{152}4=0\\\\ \big(x+\frac{11}2\big)^2-\frac{273}4=0\\\\ \big(x+\frac{11}2\big)^2=\frac{273}4[/tex]

Regular quadrilateral pyramid with base edge b=55 mm and lateral edge l = 7cm. Find the sum of all edges
Answer:
50cm or 500mm
Step-by-step explanation:
There are 4 base edges and 4 lateral edges, therefore, multiply the number for both edges by 4 and add.
Considering the fact that we were given two units of measurement, millimeters and centimeters, but we know that there are 10mm (millimeters) in a cm (centimeter) , we can just divide 55 by 10 to get 5.5.
¦
Therefore;
5.5 x 4 = 22
7 x 4 = 28
28 + 22 = 50cm

Can you make y=-(x+2)^2+17 standard form?
Answer:
y = - x² - 4x + 13
Step-by-step explanation:
The equation of a parabola in standard form is
y = ax² + bx + c ( a ≠ 0 )
Given
y = - (x + 2)² + 17 ← expand factor using FOIL
= - (x² + 4x + 4) + 17 ← distribute parenthesis by - 1
= - x² - 4x - 4 + 17 ← collect like terms
y = - x² - 4x + 13
Answer:
y = -x² -4x +13
Step-by-step explanation:
y = - ( x+2)² + 17
y = - x² -4x -4 +17
y = -x² -4x +13
Look at this set of ordered pairs:
(18, 17)
(12, 11)
(0,8)
(6, 7)
Is this relation a function?
yes
no
Answer: Yes
If I remember correctly, I believe these ordered pairs indicate a function, as there is exactly 1 output for every input (i.e., (output, input)). If there were 2 inputs of the same number, that'd make this relation not a function.

A worker earns a 3% increase in her annual salary for each of 5 years. They plan to continue working in their position for an additional n years. If they continue to earn a 3% increase in their annual salary, what statement could describes the expression that can be used to calculate the total percent increase in their annual salary from the first year to the last year
Answer:
Given that a worker earns a 3% increase in her annual salary for each of 5 years, and they plan to continue working in their position for an additional N years, if they continue to earn a 3% increase in their annual salary, to determine what statement could describe the expression that can be used to calculate the total percent increase in their annual salary from the first year to the last year the following calculation should be performed:
1 + 0.03 (interest rate) ^ N (number of years) = final interest rate
1.03 ^ N = Final interest rate
Thus, for example, if it were invested for 5 years, the equation would operate as follows:
1.03 ^ 5 = X
1.16 = X
The total percent increase in their annual salary from the first year to the last year is [tex](1.03)^n[/tex].
What is Percentage?A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
As it is given that the annual salary of the worker increases at a rate of 3%. therefore, the salary of the worker increases compounded at a rate of 3% annually. Therefore, the salary of the worker after n number of years can be written as,
[tex]A = P(1+\dfrac{r}{100})^n[/tex]
where A is the final salary of the worker, P is the initial salary of the worker, r is the rate at which the salary is increasing, and n is the number of years.
Substituting the values in the formula,
[tex]A = P(1+\dfrac{3}{100})^n\\\\A = P(1.03)^n[/tex]
Hence, the total percent increase in their annual salary from the first year to the last year is [tex](1.03)^n[/tex].
