Answer:
(x+1) • (x-5)
Step-by-step explanation:
The first term is, x2 its coefficient is 1 .
The middle term is, -4x its coefficient is -4 .
The last term, "the constant", is -5
Step-1 : Multiply the coefficient of the first term by the constant 1 • -5 = -5
Step-2 : Find two factors of -5 whose sum equals the coefficient of the middle term, which is -4 .
-5 + 1 = -4 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and 1
x2 - 5x + 1x - 5

answer
£2
explanation
12÷50%=6
12÷33%=4
6+4=10
12-10=2
Answer:
2.04 pounds left.
Step-by-step explanation:
Whitney has 12 pounds pocket money
She spends 50% of it on magazines
50% of 12 pounds is 50/100 * 12 = 600/100 = 6 pounds
33% of 12 pounds is 33/100 * 12 = 395/100 3.96 pounds
Total Spent 9.96 pounds
Amount left = 12 - 9.96 = 2.04
She has 2.04 pounds left.
Mahesh borrows a certain sum of money from a bank at 9% p.a. simple interest and invests the same sum to Rakesh at 10% p.a. compound interest compounded annually Mahesh makes a profit of Rs 7,550 after 3 years. a) What is the sum that Mahesh borrowed? b) Calculate the interest that Mahesh has to pay. c) Calculate the interest that Rakesh has to pay. d) By what percent does Rakesh pay more interest than Mahesh?
The sum that Mahesh borrowed was Rs. 22,800, the interest that Mahesh has to pay was Rs. 6,492, the interest that Rakesh has to pay was Rs. 7,550, and the percentage by which Rakesh pays more interest than Mahesh was 16.3%.
a) Sum borrowed by Mahesh
Let us suppose that the principal sum borrowed by Mahesh from the bank at 9% per annum is Rs. x.
Hence, we can write that
Simple Interest = (P × R × T )/ 100
= (x × 9 × 3)/100
= 27x/100
Therefore, the amount that Mahesh has to pay after 3 years, including the interest, is
A = P + SI
= x + 27x/100
= 127x/100
Again, Mahesh invests the same amount of Rs. x to Rakesh at 10% per annum, which is compounded annually, for three years.
Hence, the total amount after three years that Rakesh has to pay Mahesh is:
Amount after 3 years = x (1 + R/100)³
= x (1 + 10/100)³ = 1.331 x
Therefore, Mahesh made a profit of Rs. 7,550 by investing Rs. x at 10% per annum, compounded annually, for three years.
Hence, we can write that
Compound Interest = Amount - Principal
CI = 1.331x - x = 0.331x
Therefore, 0.331x = Rs. 7,550=>
x = Rs. 22,800
Thus, Mahesh borrowed Rs. 22,800 from the bank.
b) Interest that Mahesh has to pay
Interest = P × R × T/100
= Rs. 22,800 × 9 × 3/100 = Rs. 6,492
Therefore, Mahesh has to pay Rs. 6,492 as interest.
c) Interest that Rakesh has to pay
The total amount that Rakesh has to pay to Mahesh is Rs. 30,350 [= (22,800 + 7,550)].
Therefore, interest that Rakesh has to pay = Total Amount - Principal
= Rs. 30,350 - Rs. 22,800 = Rs. 7,550
Therefore, Rakesh has to pay Rs. 7,550 as interest.
d) Percentage by which Rakesh pays more interest than Mahesh
Let us calculate the percentage difference between the interest paid by Rakesh and the interest paid by Mahesh.
Thus, the percentage difference can be calculated as
% Difference = (|Interest paid by Rakesh - Interest paid by Mahesh|/ Interest paid by Mahesh) × 100
% Difference = (|7,550 - 6,492|/6,492) × 100
% Difference = 16.3%
Therefore, Rakesh pays more interest than Mahesh by 16.3%.

You will drop the bottle/water mass so that it hits the lever at different speeds. Since an object in free fall is accelerated by gravity, you need to determine the heights necessary to drop the bottle to achieve the speeds of 2 m/s, 3 m/s, 4 m/s, 5 m/s, and 6 m/s. Use the equation Ht = v squared over 2 g. to calculate the height, where Ht is the height, v is the speed (velocity), and g is the gravitational acceleration of 9.8 m/s2. Record these heights in Table B. To achieve a speed of 2 m/s, the bottle must be dropped at m. To achieve a speed of 3 m/s, the bottle must be dropped at m. To achieve a speed of 4 m/s, the bottle must be dropped at m. To achieve a speed of 5 m/s, the bottle must be dropped at m. To achieve a speed of 6 m/s, the bottle must be dropped at m

Answer:
\(A = 19.4\)
\(B = 77.6\)
\(C =83\)
Step-by-step explanation:
Given
By interpreting each line, we have:
\(B = 4A\)
\(C = 5A -14\)
Required
Solve for A, B and C
In a triangle,
\(A + B + C = 180\)

Which of the following shows the image T of triangle ABC under the transformation (x,y)→(x−4,y+1)?
The required image T of triangle ABC under the transformation (x,y) → (x-4, y+1) is formed by connecting the vertices A'(a-4, b+1), B'(c-4, d+1), and C'(e-4, f+1)
To find the image T of triangle ABC under the transformation (x,y) → (x-4, y+1), apply this transformation to each of the vertices of triangle ABC and then connect the new vertices to form the image T.
Let's assume that the coordinates of the vertices of triangle ABC are A(a,b), B(c,d), and C(e,f).
To find the image of vertex A under the transformation, we substitute x = a and y = b into the transformation equation:
(x,y) → (x-4, y+1)
(a,b) → (a-4, b+1)
Therefore, the image of vertex A is A'(a-4, b+1).
Similarly, we can find the images of vertices B and C:
B'(c-4, d+1)
C'(e-4, f+1)
Therefore, the image T of triangle ABC under the transformation (x,y) → (x-4, y+1) is formed by connecting the vertices A'(a-4, b+1), B'(c-4, d+1), and C'(e-4, f+1)

How many gallons of a 50% antifreeze solution must be mixed with 70 gallons of 10% antifreeze to get a mixture that is 40% antifreeze?
Answer: 180 gallons needed
Step-by-step explanation:
Zykeith,
Assume x gallons of 50% antifreeze is needed
Final mixture is x + 60 gallons
Amount of antifreeze in mixture is 0.4*(x+60)
Amount of antifreeze added is .5x + .1*60 = .5x + 6
so .5x + 6 = .4(x + 60)
.5x -.4x = 24 -6
.1x = 18
x = 180
Let x be the number of gallons of the 50% antifreeze solution needed. We know that the resulting mixture will be 70 + x gallons. To get a 40% antifreeze mixture, we can set up the following equation:
\({\implies 0.5x + 0.1(70) = 0.4(70 + x)}\)
Simplifying the equation:
\(\qquad\implies 0.5x + 7 = 28 + 0.4x\)
\(\qquad\quad\implies 0.1x = 21\)
\(\qquad\qquad\implies \bold{x = 210}\)
\(\therefore\) We need 210 gallons of the 50% antifreeze solution to mix with 70 gallons of 10% antifreeze to get a mixture that is 40% antifreeze.
