Five friends take a maths test
Adam, Brandon, Chen together together scored 200 marks
Brandon, Chen and Damion together scored 215
Chen, Damion, Erica together scored 224
Damion and Erica scored more than Chen
The five of them together scored 350 marks
What are their individual scores
Answer:
[tex]Adam = 60[/tex]
[tex]Brandon = 66[/tex]
[tex]Chen = 74[/tex]
[tex]Damion = 75[/tex]
[tex]Erica = 75[/tex]
Step-by-step explanation:
Given
Represent each friend with the first letter of their name
So:
[tex]A + B + C =200[/tex]
[tex]B + C + D = 215[/tex]
[tex]C + D +E= 224[/tex]
[tex]A + B + C + D + E = 350[/tex]
[tex]D , E > C[/tex]
Substitute: [tex]A + B + C =200[/tex] in [tex]A + B + C + D + E = 350[/tex]
[tex]200 + D + E = 350[/tex]
Collect like terms
[tex]D + E = 350-200[/tex]
[tex]D + E = 150[/tex]
Make D + E the subject in [tex]C + D +E= 224[/tex]
[tex]D + E = 224 - C[/tex]
Substitute [tex]D + E = 224 - C[/tex] in [tex]D + E = 150[/tex]
[tex]224 - C = 150[/tex]
Collect like terms
[tex]C = 224 - 150[/tex]
[tex]C = 74[/tex]
Substitute [tex]C = 74[/tex] in [tex]A + B + C =200[/tex] and [tex]B + C + D = 215[/tex]
[tex]A + B + 74 = 200[/tex]
[tex]A + B =- 74 + 200[/tex]
[tex]A + B =126[/tex]
[tex]B + 74 + D = 215[/tex]
[tex]B + D = -74 + 215[/tex]
[tex]B + D = 141[/tex]
So, we have:
[tex]A + B =126[/tex]
[tex]B + D = 141[/tex]
[tex]D + E = 150[/tex]
We have: [tex]D , E > C[/tex]
i.e.
[tex]D , E > 74[/tex] and [tex]D + E = 150[/tex]
For [tex]D , E > 74[/tex] and [tex]D + E = 150[/tex] to be true,
[tex]D = E = 75[/tex]
i.e.
[tex]75 + 75 = 150[/tex]
So, we have:
[tex]D = 75[/tex]
[tex]E = 75[/tex]
[tex]B + D = 141[/tex]
[tex]B + 75 = 141[/tex]
[tex]B = 141 - 75[/tex]
[tex]B = 66[/tex]
[tex]A + B =126[/tex]
[tex]A + 66 = 126[/tex]
[tex]A = 126 - 66[/tex]
[tex]A = 60[/tex]

In a lab experiment, 2400 bacteria are placed in a petri dish. The conditions are such
that the number of bacteria is able to double every 19 hours. How long would it be, to
the nearest tenth of an hour, until there are 3300 bacteria present?
Answer:
It takes 8.7 hours for there to be 3300 bacteria present.
Step-by-step explanation:
Exponential equation for population growth:
The exponential equation for population growth is given by:
[tex]P(t) = P(0)(1+r)^t[/tex]
In which P(0) is the initial population and r is the growth rate.
2400 bacteria are placed in a petri dish.
This means that [tex]P(0) = 2400[/tex]
So
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]P(t) = 2400(1+r)^t[/tex]
The conditions are such that the number of bacteria is able to double every 19 hours.
This means that [tex]P(19) = 2P(0)[/tex]. We use this to find 1 + r.
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]2P(0) = P(0)(1+r)^{19}[/tex]
[tex](1+r)^{19} = 2[/tex]
[tex]\sqrt[19]{(1+r)^{19}} = \sqrt[19]{2}[/tex]
[tex]1 + r = 2^{\frac{1}{19}}[/tex]
[tex]1 + r = 1.03715504445[/tex]
So
[tex]P(t) = 2400(1+r)^t[/tex]
[tex]P(t) = 2400(1.03715504445)^t[/tex]
How long would it be, to the nearest tenth of an hour, until there are 3300 bacteria present?
This is t for which [tex]P(t) = 3300[/tex]. So
[tex]P(t) = 2400(1.03715504445)^t[/tex]
[tex]2400(1.03715504445)^t = 3300[/tex]
[tex](1.03715504445)^t = \frac{3300}{2400}[/tex]
[tex]\log{(1.03715504445)^t} = \log{\frac{33}{24}}[/tex]
[tex]t\log{1.03715504445} = \log{\frac{33}{24}}[/tex]
[tex]t = \frac{\log{\frac{33}{24}}}{\log{1.03715504445}}[/tex]
[tex]t = 8.7[/tex]
It takes 8.7 hours for there to be 3300 bacteria present.

Answer:
32
Step-by-step explanation:
Remember angles in a triangle add up to equal 180 degrees
This means that x + 126 + 22 must equal 180
126 + 22 = 148
x + 148 = 180
subtract 148 from each side
148 - 148 cancels out
180 - 148 = 32
we're left with x = 32
Answer:
32 is the answer of above questions.

Answer:
28.3 (b)
Step-by-step explanation:
To solve circumference, you will need to use the equation C = 2 *pi* r
for this, we will use 3.14 for pi and the radius is 4.5 so this is how we need to solve it
C= 2 pi (4.5) Solve 2*4.5
C= 9 pi Now we input 3.14 for pi and multiply
C= 9(3.14)
C= 28.26 Now we round to the nearest tenth to get
C=28.3

interest rate is 8.9%?
A. 0.74
B. 0.74
C. 0.0074
D. 0.0089
Answer:
c
Step-by-step explanation:
<3
The monthly rate of interest is 0.0074. Therefore, option C is the correct answer.
What is the rate of interest?An interest rate tells you how high the cost of borrowing is, or high the rewards are for saving. So, if you're a borrower, the interest rate is the amount you are charged for borrowing money, shown as a percentage of the total amount of the loan.
The given rate of interest is 8.9%.
The monthly payment formula is M = Pr(1+ r)ⁿ/(1+ r)ⁿ - 1
Here, rate of interest
= 8.9%/12
= 0.089/12
= 0.0074
Therefore, option C is the correct answer.

You deposit $800 in an account that pays 3.6% annual interest compounded quarterly. When does your balance first exceed $1200?
Answer:
It would take 4 years. The formula for continuously compounded interest is: where P is the principal, r is the interest rate as a decimal number, and t is the number of years.
Step-by-step explanation:
You deposit $800 in an account that pays 3.6% annual interest compounded quarterly. after 11 years your balance first exceed $1200.
How to find the compound interest?If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:
[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]
You deposit $800 in an account that pays 3.6% annual interest compounded quarterly.
[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]
[tex]1200 = 800(1 + \dfrac{3.6}{4})^{4t}\\\\300 = (1 + 0.9)^{4t}\\\\t = 11.4[/tex]

Four less than two times a number is seven times the sum of that number and 8. Which equation
could be used to solve this problem?
1. 4- 2n + 7n = 8
2. 2n - 4 = 7n + 8
3. 2n - 4 = 7(n + 8)
4. 4 - 2n = 7(n + 8)
9514 1404 393
Answer:
3. 2n - 4 = 7(n + 8)
Step-by-step explanation:
Two times a number is 2n. Four less than 2n is (2n-4). The sum of a number and 8 is (n+8). Seven times that sum is 7(n+8). The statement says these values are equal:
2n -4 = 7(n +8)

Answer:
Distances:
A=1/2
B= 1
C= 3/2
Heights:
D= 1
E= 0
F= -1
Step-by-step explanation:
The distances asked in the circle are a = 1 / 2 π, b = 1π, and c = 3 / 2 π.
What is distance?Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are. In physics or everyday usage, distance may refer to a physical length or an estimation based on other criteria.
The complete movement of an object, regardless of direction, is referred to as distance.
The amount of ground a thing travels from its starting point to its destination is also referred to as distance.
Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.
Given, is a table defining the relations between the distance and the radius and time in references to a circle,
we need to find the distances, according to the question asked,
Since, we know that,
The time, t = π / 2 sec,
Also,
Calculate the distance by using the formula given below,
Distance = radius x time
So, for distance, a = 1 × π / 2 = π / 2
for distance, b = 1 × π = π
for distance, c = 1 × 3 π / 2 = 3 π / 2
Therefore,
We get, the distance of a = 1 / 2 pi, b = 1 pi, and c = 3 / 2 pi.
Hence, the distances asked in the circle are a = 1 / 2 π, b = 1π, and c = 3 / 2 π.

Trish is shopping for a new vacuum online. The
reviews for the vacuum she wants show that 104
people gave the product 5-stars. If this number
represents 65% of the reviews left for the product,
how many total reviews were left for the product?
67.6
77
160
184
Answer: 160
Step-by-step explanation:
Based on the information given in the question, let the total reviews left for the product be represented by x.
Therefore, 65% of x = 104
65% × x = 104
0.65 × x = 104
0.65x = 104
x = 104/0.65
x = 160
Therefore, 160 reviews were left for the product.
