Kwame and Ama shared an amount of money in the ratio 5:4 respectively. If Kwame had GHC 9.00, how much did they share?
Answer:
They shared GHC16.2
Step-by-step explanation:
Here, we want to get the amount shared
Let us call the amount x
Total ratio is 5 + 4 = 9
Kwame had GHC 9
Thus;
5/9 * x = 9
5 * x = 9 * 9
5x = 81
x = 81/5
x = GHC 16.2

What is the cube root of 216x^9y^18 ?
A: 4x^3y^6
B: 6x^3y^6
C: 72x^6y^15
D: 213x^6y^15
[tex]4 {x}^{3} {y}^{6} [/tex]
OPTION A
Answer:
option B
Step-by-step explanation:
Cube root of x means [tex]x^{\frac{1}{3}[/tex]
Formulas used :
[tex](a^x)^y = a^{xy}[/tex]
[tex](b^3)^{\frac{1}{3}} = b[/tex]
Therefore cube root of :
[tex](216 x^9 y^{18})^{\frac{1}{3}} = (6^3 \times (x^3)^3 \times (y^6)^3)^{\frac{1}{3}}[/tex]
[tex]= (6^3)^{\frac{1}{3}} \times ((x^3)^3)^{\frac{1}{3}} \times ((y^6)^3)^{\frac{1}{3}}[/tex]
[tex]= 6 \times x^3 \times y^6[/tex]
[tex]=6x^3y^6[/tex]

Help pls, I’m confused
Answer:
(x + y)² = 25
Step-by-step explanation:
The expansion of (x + y)² is
(x + y)² = x² + y² + 2xy ← substitute x² + y² = 15 and xy = 5
= 15 + 2(5)
= 15 + 10
= 25

2) Find the remainder when x3 + x2 - 20 is divided by
(x + 2) by using remainder theorem.
{ANS: R = -24}
Answer:
Remainder = –24
Step-by-step explanation:
x³ + x² – 20 divide by x + 2
We can obtain the remainder when
x³ + x² – 20 is divided by x + 2 using the remainder theorem as follow:
We'll begin by calculating the value of x from x + 2. This is illustrated below:
x + 2 = 0
Collect like terms
x = 0 – 2
x = –2
Finally, we shall determine the remainder by substituting –2 for x in
x³ + x² – 20. This is illustrated below:
x³ + x² – 20
x = –2
Remainder = (–2)³ + (–2)² – 20
Remainder = –8 + 4 – 20
Remainder = –24
Therefore, the ramainder when
x³ + x² – 20 is divided by x + 2 is –24

What are the x-intercepts of the equation y=4x^2-16
Answer:
x = ± 2
Step-by-step explanation:
To find the x- intercepts let y = 0 , that is
4x² - 16 = 0 (add 16 to both sides )
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take the square root of both sides )
x = ± [tex]\sqrt{4}[/tex] = ± 2
The x- intercepts are x = - 2 and x = 2
Answer:
I love algebra anyways
the ans is in the picture with the steps

Step-by-step explanation:
Which interval or union of intervals represents the values for which f(x) is ≤ 0? Select the correct choice below and fill in the answer boxes to complete your choice.
Answer:
(-∞, -1]∪{5}
Step-by-step explanation:
We know that:
f(x) ≤ 0 is true if the graph of the function is intersecting the x-axis or below the x-axis.
So we can just look at the graph, we can see that in the interval:
(-∞, -1] (the value x = -1 is included, that is why we use the symbol ] instead of the parenthesis)
the graph is below or intersecting the x-axis
and this also happens at x = 5 or just denoted as {5}
Then the correct notation is:
(-∞, -1]∪{5}
Nicole buys a meal in a town with a 9% sales tax. She tips 17% on the bill before adding the sales tax. She pays a total of $15.30. What should be the original cost of her meal?
Answer:
17/100×15.30=2.60
9/100×15.30=1.37
15.30-(1.37+2.60)=11.33
Here Tran posted it
Step-by-step explanation:
1. I estimate that the error in measuring the area of the lot is about 10% so we write the area as 400 sq ft +- 10%, which means that the lot can be as small as 360 sq ft or as large as 440 sq ft. We tack on 15% more on the number of pieces of sod to account of the plot's irregularities. Since each piece of sod is 2 sq ft, the number of pieces we must get is 440/2 = 220 pieces +- 15% or 253 pieces
2. The nominal value is jus the average weight which is 59.5 g. The tolerance is (3.5g/59.5g)×100% = 5.88% and the measurement range is from 56g to 63g.

Triangle ABC ~ Triangle DEF. Measure of angle A = 30 degrees and measure of angle F = 65 degrees. AB=20, DE = 35, EF= 28.
Find measure of angles B, E, D and C and the length of BC.
Answer:
< B = 180-30-65=85°
< E = 85°
< D = 30°
< C = 65°
BC = 20/35 × 28 = 16
If triangle ABC is similar to triangle PQR, which equation is true?
AB/PO = 1
AB = PO
AB/PO = BC/QR
AB /PO = QR/BC
Answer:
AB/ PQ = BC/QR
Step-by-step explanation:
In similar triangles, ratio of corresponding sides are equal.
So, [tex]\frac{AB}{PQ}= \frac{BC}{QR}=\frac{AC}{PR}[/tex]

What are the characteristics of the graph of the inequality x ≥ -2? The ray will move to the left. The ray will move to the right. It will use an open circle. It will use a closed circle.(multiple answers)
Answer:
Step-by-step explanation:
The inequality x ≥ -2 is graphed on a number line. -2 is the smallest possible value. All subsequent values are larger and therefore lie to the right of -2.
Thus, the following are true:
1. The ray will move to the right (because x begins at -2 and increases, which means moving to the right on the number line).
2. It will use a closed circle (because x = -2 is part of the solution set).
Answer: The ray will move to the right and it will be a closed circle.

Step-by-step explanation:
Pat bought 6 shirts that were all the same price. He used a traveler's
check for $25, and then paid the difference of $86. What was the
price of each shirt?
Answer:
Each shirt costs $18.50
Step-by-step explanation:
Questions such as these usually involve quite simple calculations, but they are important in being able to convert a scenario described in words into math calculations.
First, read the information carefully and then summarize what you are given in short sentences. Pat bought 6 shirts. He paid using a check and cash.
The total amount paid was $ 25 + $ 86 = $ 111
The shirts all cost the same price.
The cost of each shirt was: 111 ÷ 6 = $ 18.50
Answer:
Each shirt was 18.50
Step-by-step explanation:
The total cost of the 6 shirts was 25+86 = 111
Divide the total by 6 to find the cost of each shirt
111/6 =18.5
Each shirt was 18.50
