Answer:

6) C

8) A

Step-by-step explanation:

6) A=(base*height)/2 is the formula for a triangle.

8) yes

6. The formula that can be used to find the total amount of paint she will need if the entire space is painted is C) A= (8)(9)/2.

The area of the triangle is given as,

Area = (1/2)*(base)*(height)

Now it is given that,

Base of space = 8 feet

Height of space = 9 feet

Thus,

Area of the space = (1/2)*(base of space)*(height of space)

⇒ Area of the space = (1/2)*(8)*(9)

or, Area of the space =  (8)(9)/2

⇒ Area of the space = 36 square feet

Thus, the formula that can be used to find the total amount of paint she will need if the entire space is painted is C) A= (8)(9)/2.

8. The properties use to solve the equation 4x + 2 = 18 is C) The inverse property of addition and then the inverse property of multiplication.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now the given equation is,

4x + 2 = 18

To solve the equation first using inverse property of addition

4x = 18 - 2

4x = 16

Now using inverse property of multiplication we get,

4x/4 = 16/4

x = 4

this is the required value of x.

Answer:

C

Step-by-step explanation:

Here in this question , we are interested in calculating the total distance covered by the train in the 10 minutes that it ran.

From the first part of the question, we already know the distances in the first 5 minutes.

Now, to calculate the total distance in the second 5 minutes, we use the distance formula since we have the average speed and the time;

Mathematically; Total distance = average speed * time

From the question, average speed is 33km/h, while time is 5 minutes. To achieve a consistent unit, we convert 5 minutes to hours.

That would be 5/60 = 1/12 hours

So the total distance in the second 5 minutes is;

33 * 1/12 = 2.75 km

Now, to calculate the total distance traveled, let’s add up the distances in the first 5 minutes and convert to kilometers;

That would be;

68 + 127 + 208 + 312 + 535 = 1,250 m

Let’s convert this to km.

We simply divide by 1000 = 1250/1000 = 1.25 km

The total distance is thus ;

1.25 + 2.75 = 4 km

Hey there!

Well when dividing fractions you need to use Keep, Change, Flip.

[tex]\frac{8}{6} / \frac{5}{4}[/tex]

Keep, Change, Flip

[tex]\frac{8}{6} * \frac{4}{5}[/tex]

[tex]\frac{32}{30}[/tex]

16/15

[tex]1 \frac{1}{15}[/tex]

Hope this helps :)

Answer:

The answer is 16/15 or 1 1/15.

Step-by-step explanation:

First, you have to multiply it by converting the second fraction upside down:

[tex] \frac{8}{6} \div \frac{5}{4} [/tex]

[tex] = \frac{8}{6} \times \frac{4}{5} [/tex]

Next, you have to cut out the common terms and multiply all:

[tex] \frac{8}{6} \times \frac{4}{5} [/tex]

[tex] = \frac{8}{3} \times \frac{2}{5} [/tex]

[tex] = \frac{16}{15} \: \: or \: \: 1 \frac{1}{15} [/tex]

y + 2 = -(x - 4)

============================================

Explanation:

The slope of this line is -1 because each time we move down 2 units, we move to the right 2 units. So slope = rise/run = -2/2 = -1

The slope formula says the same thing more or less. Let's pick the two points (0,2) and (2,0) to find the slope through them

m = (y2-y1)/(x2 - x1)

m = (0-2)/(2-0)

m = -2/2

m = -1

-------------

Using that slope and a point on the line, we can form the equation. We can pick any point really as long as it's on the line. However, to have it match with the answer choices, we'll have to pick the point (4,-2)

Turn to point slope form

y - y1 = m(x - x1)

y - y1 = -1(x - x1) ... plug in the slope

y  - (-2) = -(x - 4) ... plug in the point (x1,y1) = (4, -2)

y + 2 = -(x - 4)

Answer:

Solution : (- 9, - 3)

Step-by-step explanation:

Approach 1 : Imagine that this point (3, - 9) is rotated 90 degrees clockwise. We know that this point lies in the fourth quadrant, so if it is rotated 90 degrees, you can imagine the x - coordinate will be greater than the y - coordinate, if you take their absolute value(s). Remember that the new coordinates will also lie in the third quadrant. Based on these requirements we have the resulting point (- 9, - 3) or option c.

________________________________________

Approach 2 : There is another approach to this, a more exact approach.

Rotation of axis, θ : (x, y) --> (X, Y)

X = xcos(θ) + ysin(θ),

Y = - xsin(θ) + ycos(θ)

Here θ = 90 degrees. Substitute and solve for the exact coordinates.

X = 3cos(90) + - 9sin(90) = 3cos(90) - 9sin(90) = 3 * 0 - 9 * 1 = - 9,

Y = - 3sin(90) + - 9cos(90) = - 3sin(90) - 9cos(90) = - 3 * 1 - 9 * 0 = - 3

As you can see our solution is the same, (- 9, - 3), or option c.

Answer:

[tex] f(x) = 72 - 12x [/tex]

Step-by-step explanation:

No. of days of study = 6

Amount of food to use for the 6 days = 72 mm

Given that equal amount of food was used each day, amount used per day = [tex] \frac{72}{6} = 12 mm [/tex]

This would enable us derive a function for the amount of food remaining f(x), which can be expressed as a function of the number of days that have passed, (x).

Thus, we would have:

[tex] f(x) = 72 - 12x [/tex]

Let's check if this equation expresses the relation of the function well.

At the end of day 1, if we used, 12mm, we would have 72 - 12 = 60mm of food remaining.

If we replace x in the equation we derived, we would get the same 60mm as the amount of food remaining.

If you try 2, 3, 4, 5 days, you'd get same thing.

At the end of the study, after the 6th day, the food would remain nothing.

Replace 6 for x in the relation function derived, you'd get a value of 0.

10:11 A.M

11:00 A.M is 11 hours from 12 A.M (12 midnight)

11:00 A.M is 11 hours from 12 A.M (12 midnight)1 hour 29 minutes + 1 hour 15 minutes

11:00 A.M is 11 hours from 12 A.M (12 midnight)1 hour 29 minutes + 1 hour 15 minutes= 2 hours 49 minutes

11:00 A.M is 11 hours from 12 A.M (12 midnight)1 hour 29 minutes + 1 hour 15 minutes= 2 hours 49 minutes11 hours - 2 hours 49 minutes

11:00 A.M is 11 hours from 12 A.M (12 midnight)1 hour 29 minutes + 1 hour 15 minutes= 2 hours 49 minutes11 hours - 2 hours 49 minutes= 10 hours 11 minutes = 10:11 A.M

Therefore, she can start making the cake batter from 10:11 A.M.

9:25 am is the latest time she can start making the cake batter

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

Given that Meg is going to make a cake for her mother's birthday.

The time to bake make the cake batter is 1 hour 15 minutes.

This we can take only in minutes

1 hour = 60 minutes

So 60+15 =75 minutes to make the batter.

the cake needs to bake in the oven for 1 hour and 20 minutes

60+20=80 minutes.

Meg wants the cake to be out of the oven by 11:00 A.M.

We need to find the latest time to start the cake.

Let us find the total time to make the cake

80+75=155

155 minutes means 2 hrs 35 minutes.

Now we have to remove 2 hrs 35 minutes from 11:00 am

Which 9 hours 25 minutes.

Hence, 9:25 am is the latest time she can start making the cake batter

Hey, there!!

Let's simply work with it,

Here,

In figure ABC,

let a= 14

b= 19

and c= 8.

Using cosine rule,

[tex] {c}^{2} = {a}^{2} + {b}^{2} - 2ab.cosc[/tex]

putting value of all we get,

[tex] {8}^{2} = {14}^{2} + {19}^{2} - 2 \times 14 \times 19 \times cosx[/tex]

Now, simplifying them we get,

[tex]64 = 196 + 361 - 532.cosx[/tex]

[tex]532cosx = 557 - 64[/tex]

[tex]or \: 532cosx = 493[/tex]

[tex]or \: cosx = \frac{493}{532} [/tex]

cosx= 0.926691

Putting cos inverse,

[tex]x = {cos}^{ - 1} (0.926691) [/tex]

Therefore, x= 22.0752°

By rounding off we get,

x= 22° { as 0 is smaller than 5 itsvalue dont change}.
