The gas tank in my car is 5/6 full . Each time I drive it to or from work I use 1/12 of a full tank of gas . Which equation represents the number of times I can drive to or from work with the gas in my tank

Answers

Answer:

5/6 = 1/12x

Step-by-step explanation:

x represents the amount of times you can can drive to or from work with the gas in the tank

5/6 = 1/12x

- Multiply both sides of equation by 12

Is the equation 96 ÷ 3 = 72 ÷ 2 true or false?
True
False

Answers

Answer:

false

Step-by-step explanation:

96/3=32

72/2=36

The answer to this equation for 96/3=24
Because if you want to check do 24(3)=96

Now you’re doing 24/2 which equals to 12 also to check do 12(2)=24, therefore this equation is false

1 invest £4600 in a bank account
paying
2.1%
compound interest. How much do I have in the account
after 5 years?

Answers

Answer:

£5083

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 2.1%/100 = 0.021 per year,

then, solving our equation

I = 4600 × 0.021 × 5 = 483

I = £ 483.00

The simple interest accumulated

on a principal of £ 4,600.00

at a rate of 2.1% per year

for 5 years is £ 483.00.

Using the normal distribution, the mean of T is of 30 seconds.

How to get the z scores?

If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.

If we have

[tex]X \sim N(\mu, \sigma)[/tex]

[tex]Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)[/tex]

The mean of T is 10 seconds

A normal distribution has two parameters: Mean  and standard deviation .

The given parameters are the mean completion time of each step, μ = 10 seconds

The standard deviation, σ = 5 seconds.

For the total completion, there are 3 instances, hence ,n = 3(10)

Thus, the mean of T is of 30 seconds.

Angles and Lines

The figure attached below has been completed with the angle y to support the calculations to come.

The sum of the interior angles of a rectangle is 180°. Applying on triangle PQR:

30 + 4x + 2 + y = 180

Simplifying:

32 + 4x + y = 180

Solving for y:

y = 180 - 32 - 4x

y = 148 - 4x

Angles y and 8 + 6x are a linear pair, i.e. their sum is 180°, thus:

y + 8 + 6x = 180

Substituting y from the equation above:

148 - 4x + 8 + 6x = 180

Simplifying:

156 + 2x = 180

Dividing by 2:

78 + x = 90

Subtracting 78:

x = 90 - 78

x = 12

Triangle ABC is similar to triangle DEF

Answer:

Step-by-step explanation:

AC = 5

DF = 15

5 x 3 = 15

BC = 3

EF = 9

3 x 3 = 9

Do you see the pattern? So as you can see the difference between Triangle ABC and DEF is the multiply/divide 3 so if you want to find DE then you should set it up as:

[tex]\frac{4}{3}[/tex] = [tex]\frac{DE}{9}[/tex]  and to check if its right if you solve it you get [tex]\frac{4}{3}[/tex] = [tex]\frac{12}{9}[/tex]

and as you see [tex]\frac{12}{9}[/tex] and [tex]\frac{4}{3}[/tex] are literally the same thing just you need to simplify [tex]\frac{12}{9}[/tex]

Bradley Wiggins cycles 2.5km on a warm up. If the diameter of Bradley's bike wheel is 68cm, how many times (to the nearest whole rotation) will Bradley's bike wheel have rotated on this journey?

Answers

Answer:

1171 rotations

Step-by-step explanation:

Given that:

Distance cycled = 2.5km

Diameter of bike wheel, d = 68cm = 0.68m

We obtain the Circumference of the bike wheel:

Circumference, C = πd

C = 3.14 * 0.68

C = 2.1352 m

The number of rotations Bradley's wheel will make will be :

Total distance cycled / Circumference

= (2.5 *1000)m / 2.1352m

= 2500 / 2.1352

= 1170.8505

= 1171 rotations

The hospital has found that if a patient is being visited on average at least 8.4 times per day, they can give the same patient care with 3 less nurse visits per day. How many nurse visits per day can the hospital reduce for these 13 patients?

Answers

Answer:

6

Step-by-step explanation:

the number of patients that get visted 8.4 times is 1 and another 1 at 8.3 add those up and mutiply by the 3 less nurses visits you get 6

Number of nurse hours  the hospital can reduce is 6.

What is an expression?

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Number of patients visited on average at least 8.4 times per day = 2 patients

Now for each of the 2 patients the hospital can reduce 3 nurse visits.

Thus,

Number of nurse hours the hospital can reduce = 3 x 2

⇒ Number of nurse hours the hospital can reduce = 6 hours

Thus, Number of nurse hours  the hospital can reduce is 6.

Complete Question

Diego is preparing brownies and cookies for a bake sale. He would like to make equal-size bags for selling all of the 48 brownies and 64 cookies that he has. What is the largest number of combination bags that Diego can make with no left over? Explain how you know this is the largest possible number of bags?

Answer:

16 bags.

Step-by-step explanation:

From the question, we have:

48 brownies and 64 cookies that he has

Hence, we solve this question using Greatest common factor method.

The first step would be to find the factors of 48 and 64. We would then pick the Greatest (largest factor) common to both.

The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

The factors of 64 are: 1, 2, 4, 8, 16, 32, 64

Then the greatest common factor is 16.

Therefore, the largest number of combination bags that Diego can make with no left over is 16 bags

Find the coordinates of the orthocenter of a triangle with the vertices (0,0), (8,2), (2,8) at each set of points on a coordinate plane?

Answers

Answer:

coordinates of the orthocenter = (16/5, 16/5)

Step-by-step explanation:

I have drawn a diagram showing this triangle with the vertices. I have also drawn altitude from B perpendicular to AC at point E.

I have also drawn altitude from from A perpendicular to BC at point D.

Now, we will find the slope of AC from the line slope equation; (y - y1) = m(x - x1)

m = (y - y1)/(x - x1)

Our coordinates are; A(0,0), B(8,2), C(2,8).

Thus;

Slope of AC; m = (8 - 0)/(2 - 0)

m = 4

Since BE is perpendicular to AC, slope of BE = -1/slope of AC = -1/4

Thus, equation of BE is;

(y - 2) = -¼(x - 8)

Multiply through by 4 to get;

4y - 8 = -x + 8

x + 4y = 16

Slope of BC is; m = (8 - 2)/(2 - 8) = 6/-6 = -1

AD is perpendicular to BC, thus slope of AD = -1/-1 = 1

Equation of AD is;

(y - 0) = 1(x - 0)

y = x

Putting x for y in equation of BE, we have;

x + 4x = 16

5x = 16

x = 16/5

Since y = x in equation AD, then y = 16/5

coordinates of the orthocenter = (16/5, 16/5)
