Omar invests £6000 for 4 years in a savings account. He will get 1.5 % per year compound interest. Work out the total amount of that will be in Omar accounts by the end of the 4 years. Round your answer to the nearest pound.
The answer is either
6361
6369
6360
Or 6368
Answers
Answer:
£6368
Step-by-step explanation:
You can start by making a formula, which will be:
100/100=1
1.5/100=0.015
1+0.015=1.015 (your multiplyer)
6000*1.015^n= your money after 4 years
(n represents the number of years)
Now you just put in the number of years:
6000*1.015^4=6368.181304
Now round:
Answed= £6368

Step-by-step explanation:
step 1. the x intercept is when y=0.
step 2. 2x -5(0) = 20 or x = 10.
step 3. the x intercept is (10, 0)
step 4. the y intercept is when x=0.
step 5. 2(0) - 5y = 20 or y = -4
step 6. the y intercept is (0, -4).

A bicycle helmet has a selling price of $50. The helmet is discounted 30% off the selling price. The sales tax rate is 6%. What is the total cost of the helmet?
Answers
Multiply by the cost of the helmet, $50
50 x 0.30 = $15, the amount of the discount.
50-15 = $35, the sale price of the helmet.
For the sales tax, again, convert to a decimal by dividing by 100 = 0.06
35 x 0.06 = 2.10, the amount of sales tax
$35 + $2.10 = $37.10, total cost with tax

Then

Solve the equations
3a + b = 10 and 2a + 4b =0.
3a + b = 10
2a + 4b=0
Answers
Answer:
a = 4 , b = -2
Step-by-step explanation:
3a + b = 10
2a + 4b = 0
(By using elimination method, eliminate one variable) - to get only one equation
(3a + b = 10 ) 4
2a + 4b = 0
12a + 4b = 40
(minus)
2a + 4b = 0
10a = 40
a = 40/10
a = 4
(substitute a into an equation to get b)
2a + 4b = 0
2(4) + 4b = 0
4b = 0 - 8
b = -8/4
b = -2

What is the slope of a line parallel to the line with equation 2x+4y=8
Answers
Answer:
m = [tex]\frac{-1}{2}[/tex]
Step-by-step explanation:
To find the slope of most lines, we should rearrange the equation into the slope-intercept form or y = mx + b.
So,
2x + 4y = 8
4y = -2x + 8
[tex]y=\frac{-2x +8}{4}[/tex]
[tex]y=\frac{-2}{4}x+\frac{8}{4}[/tex]
[tex]y=\frac{-1}{2}x+2[/tex]
The slope is the coefficient of the x term, so
m = [tex]\frac{-1}{2}[/tex]
Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
2x+4y=8
4y = -2x +8
y = [tex]-\frac{2}{4}[/tex]x + [tex]\frac{8}{4}[/tex]
y = [tex]-\frac{1}{2}[/tex]x + 2
y=mx+b so the slope is m=[tex]-\frac{1}{2}[/tex].

The students in Mr.Collin's class used a surveyor's measuring device to find the angle from their location to the top of a building. They also measured their distance from the bottom of the building. The diagram shows the angle measure and the distance. To the nearest foot, what is the height of the building?
a. 105 ft
b. 116 ft
c. 32 ft
d. 54 ft
Answers
The height of the building is approximately 105 ft.
According to the question,
We have the following information:
The angle made from their location to the building = 59°
The distance of the building from their location = 63 ft
Now, we can find the height of the building by using trigonometric function of tan.
We know that tan is equal to perpendicular/base.
In this case, perpendicular is the height of the building and base is the distance of the location from the building.
We have:
Tan 59° = Height of the building/distance of the building from the location
We know that the value of tan 59° is 1.6643.
Let's take the height of the building to be H ft.
1.6643 = H/63
H = 1.6643*63 ft
H = 104.85 ft
Now, this number can be rounded off to 105 ft.
Hence, the correct option is a.
