Answer:
1. C. 1/4(4) + 1/4(9) (A, 1/4(13), is essentially C simplified (without figuring it out).)
2. G - -4
3. A - -4(-5) + (-4)x
4. J - 1/6x + 1/6y
5. A - 60(10 + 2)
Step-by-step explanation:
1.
1/4(4 + 9) We can distribute 1/4 into 4 and 9.
1/4(4) + 1/4(9) Now while we have our answer, this can be further simplified.
1/4(13) What's on the left is the simplified 2-term equation.
So really, either C or A will be the answer. But due to the format of #3, I put C as my answer. B & D were out because there wasn't any extra multiplication.
2.
-2/5(15 - 5) Subtract 5 from 15 to get 10.
-2/5(10) Multiply -2/5 by 10 to get -20/5
-20/5 Divide -20 by 5 to get -4.
-4, so G is the answer. This was negative, so H & J were out to begin with. F was out as soon as I solved the problem.
3.
-4(-5 + x) Distribute -4 into -5 + x.
-4(-5) + (-4)x, so A is the answer. Don't get tricked! B may look right, but there should be a negative sign in front of the 5, hence why it's incorrect.
4.
1/6(x + y) Distribute 1/6 into x + y.
1/6x + 1/6y, so J is the answer. F & G are already out because you don't multiply the variables by each other. H is also out because there wasn't any multiplication involved other than x + y being multiplied by 1/6.
5.
Only 60(10 + 2) would have worked, so A is the answer. The tickets would have cost 720 dollars (600 + 120). B would have equated to 624 (24 + 600), C would have been 132 (6 * 22), and D would have been 600. (10 * 60).

A person invested $3,500 in an account growing at a rate allowing the money to double every 15 years. How long, to the nearest tenth of a year would it take for the value of the account to reach$7,700?
Answer:
30 years and a half
Step-by-step explanation:
well let's just say 3.5k x hmm 2? at an estimate and that will get us to 7000.. so in order to get to 7000 we have to wait 15 years which is 30 years and a half. From Xthermyx. A brainly user.
It would take 22.7 years for the value of the account to reach $7,700.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
Since the money in the account is doubling every 15 years.
The following equation is used to find the time it takes to reach a certain value:
t = (ln(P/F))/(ln(1+r))
where:
P = the initial investment amount
F = the future value we want to reach
r = the growth rate per period
ln = natural logarithm
t = the number of years it takes to reach F
P = $3,500
F = $7,700
r = ln(2)/15 (since the money is doubling every 15 years).
Plugging these values into the equation.
t = (ln(3500/7700)) / (ln(1+ln(2)/15))
t = ln (5/11) / ln (1 + 0.30/15)
t = 22.7
Therefore,
It would take 22.7 years for the value of the account to reach $7,700.

Numbers, figures, objects, or symbols arranged in a definite order or sequence
is often encountered in Mathematics. For instance.
(a) 2, 4, 6, ...
(b)
(c) A. D. G, J.
Numbers in (a), figures in (b), and letters in (c) are arranged in a definite order
Using the given sequences:
1. What is the next number in (a)?
2. What is the next figure in (b)?
3. What is the next letter in (c)?
Answer:
(a) Next number is 8
(c) Next alphabet is M
Step-by-step explanation:
Given
[tex](a)\ 2, 4, 6[/tex]
[tex](c)\ A, D, G, J[/tex]
Solving (a): The next number
In the given sequence, each item is gotten by adding 2 to the previous item.
i.e.
[tex]4 \to 2 + 2[/tex]
[tex]6 \to 4 + 2[/tex]
So, the rule is: Add 2
Hence, the next number is:
[tex]Next = 6 + 2[/tex]
[tex]Next = 8[/tex]
Solving (c): The next letter
In the given sequence, each letter is gotten by skipping two alphabets i.e.
[tex]D \to A []\ [] D[/tex]
[tex]G \to D []\ [] G[/tex]
[tex]J \to G []\ [] J[/tex]
So, the rule is: skip 2 alphabets
[tex]Next: J \ []\ [] M[/tex]
The next letter is M
Solving (b); The next figure
This question requires an attachment.
Since, none is given; I will give a general explanation.
First, you need to study the pattern, identify the rule, then apply the rule
Take for instance, the attached image.
The pattern follows that:
1 layer, 3 dots
2 layers, 6 dots
3 layers, 9 dots
4 layers, 12 dots
This implies that,
Rule: Add 1 layer and 3 dots
So, the next will be:
5 layers, 15 dots

Suppose you invest $130 a month for 5 years into an account earning 8% compounded monthly. After 5 years, you leave the money, without making additional deposits, in the account for another 25 years. How much will you have in the end?
Answer:
FV= $70,887.15
Step-by-step explanation:
First, we need to calculate the future value of the $130 deposit for 5 years:
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit= $130
i= 0.08/12= 0.0067
n= 5*12= 60 months
FV= {130*[(1.0067^60) - 1]} / 0.0067
FV= $9,561.96
Now, using the following formula, the future value of the investment after 25 years:
FV= PV*(1 + i)^n
n= 25*12= 300
FV= 9,561.96*(1.0067^300)
FV= $70,887.15
Andy, Bob and Chuck run a gardening business. Andy pays all the annual fixed costs (insurance, telephone line rental, etc.) by installments, which amount to $400 per week. Bob buys the materials for any job they do. Chuck collects the payment for jobs. They split all profits evenly and settle down after every job is completed. They have just done a landscaping and re-fencing job for Mrs. Smith that took the three of them exactly two weeks. Materials cost $1,400 and Mrs. Smith paid Chuck $4,900. How much does Chuck owe Andy and Bob?
Answer:
$1800
He owes them $900 each
Step-by-step explanation:
Profit = Revenue - (fixed cost + material cost)
fixed cost $400 x 2 = 800
4900 - (800 + 1400) = $2,700
Since they share the profits equally, each would get 2700/3 = 900

if Speed=80Km/h and Time=2hr then Find distance in Km?
Answer:
[tex] Distance = 160km[/tex]
Step-by-step explanation:
According to the Question ,
Speed = 80km/hr Time = 2hr Distance = ?We know the formula of speed as ,
[tex]\implies Speed \times Time = Distance \\\\\implies Distance = 80km/hr \times 2hr \\\\\implies \boxed{\boxed{ Distance = 160\ km}}[/tex]
A car starts from rest and attains a velocity of 9km/h in 5 seconds . Calculate acceleration and the displacement covered in that time
Answer:
Acceleration is 0.5 m/s² and the distance covered is 6.25 m.
Step-by-step explanation:
Given that,
Initial speed, u = 0
Final speed, v = 9 km/h = 2.5 m/s
Time, t = 5 seconds
We need to find the acceleration and the displacement covered in that time. Acceleration = rate of change of velocity
So,
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{2.5-0}{5}\\\\a=0.5\ m/s^2[/tex]
Distance d can be calculated using third equation of motion.
[tex]d=\dfrac{v^2-u^2}{2a}\\\\d=\dfrac{2.5^2-0^2}{2\times 0.5}\\\\d=6.25\ m[/tex]
So, acceleration is 0.5 m/s² and the distance covered is 6.25 m.

Justin spent 45% of his paycheck on travel expenses. If he earned $800, how much money did he spend, and how much money is left over?
Answer:
1. He spent $360
2. Amount left over = $440
Step-by-step explanation:
Let us first layout the important details in the question:
Amount earned = $800
percentage spent on travel expenses = 45% of the amount earned
45% of the amount earned
[tex]= \frac{45}{100} \times 800\\= 0.45 \times 800 = 360[/tex]
∴ Amount sent on travel = $360
To find the amount of money left over, we will simply deduct the amount spent from the total earned amount. This is done as follows:
Amount left over = Amount earned - Amount spent on travel
Amount left over = 800 - 360 = $440
∴ $440 was left over

I don’t understand question 42,43
Answer:
42. x = 25
43. LM = 11
Step-by-step explanation:
For 42, the three angles of a triangle, when added, = 180 degrees. We know that one of the angles is 90 degrees...a right angle.
So: 90 + 2x + x + 15 = 180
105 + 3x = 180
3x = 75
x = 25
If they ask for more information: the three angles are 90 degrees, 50 degrees (2x), and 40 (x + 15). 90 + 50 + 40 = 180
For 43, ray PN bisects (cuts in equal halves) the triangle. We know this because the two segments LP and PM are equal. As a result, the triangles LPM and PNM are mirror images. Since MN = 11, LM also = 11.

find the interest on $6,000 at 5% for one year
Answer:
300$
I=P×r×t
P= is the principal amount, $6000.00.
r=is the interest rate, 5% per year (you have to put it in decimal form to multiply)
t= is the time involved, which is 1 year
To find interest multiply 6000 × 0.05 × 1
