Answer:

Step-by-step explanation:

Notice that both sides involve 7a - 2a, and both involve 4.  By the associative property the order in which the addends appear is immaterial; the left side therefore equals the right side.

Answer:

7a + 4 - 2a = 7a - 2a + 4

5a + 4 = 5a + 4

Step-by-step explanation:

7a + 4 - 2a = 7a - 2a + 4

​7a + 4 - 2a

Rearrange the terms.

7a - 2a + 4

Combine like terms.

5a + 4

The left side simplifies to 5a + 4.

7a - 2a + 4

5a + 4

The right side also simplifies to 5a + 4.

Answer:

Water is leaving at 17500m^3 per minute

Step-by-step explanation:

Given

[tex]V(t)= 250(1600 - 80t + t^2)[/tex]

Required

The rate when time is 5 minutes

We have:

[tex]V(t)= 250(1600 - 80t + t^2)[/tex]

Open bracket

[tex]V(t)= 400000 - 20000t + 250t^2[/tex]

Differentiate

[tex]V'(t) = 0 - 20000 + 2*250t[/tex]

[tex]V'(t) = 0 - 20000 + 500t[/tex]

[tex]V'(t) = -20000 + 500t[/tex]

At 5 minutes, we have:

[tex]V'(5) = -20000 + 500*5[/tex]

[tex]V'(5) = -20000 + 2500[/tex]

[tex]V'(5) = -17500[/tex]

This means that water is leaving at 17500m^3 per minute

Answer:

2nd Division

Step-by-step explanation:

Given :-

And we need to tell where does 42% lies on the number line . So , since there are 4 equal divisions , therefore each division has ,

[tex]:\implies[/tex] Each division = 100% ÷ 4

[tex]:\implies[/tex] Each division = 25%

So after two divisions the marking will be 50%. Therefore , 42% lies in the second division .

Step-by-step explanation:

Answer:

36 m

Step-by-step explanation:

The area (A) of a square is calculated as

A = s² ( s is the side length )

Here A = 81 , then

s² = 81 ( take the square root of both sides )

s = [tex]\sqrt{81}[/tex] = 9

Perimeter = 4s = 4 × 9 = 36 m

Answer:

B The number of candles Sallie sells

Step-by-step explanation:

Given the equation :

y = 8x

y = amount earned ; x = number of candles sold

Cost per candle = 8

The Independent variable is the number of candles sallie sells as it is this variable which determines the amount which sallie will earn from candle sales (dependent variable). In essence, the variable which determines or affects the dependent variable is the independent variable.

Answer:

y = 5√3

x = 10√3

Step-by-step explanation:

From the given sides

Adjacent = 15

Opposite = y

Hypotenuse = x

Angle of depression = 30degree

Using the SOH CAH TOA identity

tan theta = opp/adj

tan 30 = y/15

y = 15tan30

y = 15(1/√3)

y = 15√3/3

y = 5√3

Similarly

cos theta = adj/hyp

cos 30 = 15/x

x = 15/cos30

x = 15 /√3/2

x = 30/√3

x = 30√3/3

x = 10√3

Answer: 290 cubic meters

Step-by-step explanation: First, find the volume of each figure. 3 x 6 x 5 = 90, and 5 x 5 x 8 = 200. 90 + 200 = 290

Answer:

B

Step-by-step explanation:

The standard form of a circle equation is:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius.

We can plug in the given values to get:

(x - 1)^2 + (y - 2)^2 = 3^2

This is the sam as option B

Answer: The distance between (5,3),(1,0) is 25units square.

Step-by-step explanation:

So, I usually plot the points, and conect them first.

And then I draw a right triangle, so draw two line that conect to the line that we need to find the distance, and form a triangle. Make sure that the line from point (5,3)(1,0) is the Pythagorean triples.

Next, you count the units of the two line that makes a right angle. which is 4 units for the first line, and 3 units for the second.

Thirdly, you plug the numbers into the Pythagorean equation, which is a^2+b^2=c^2 (plug it into a and b, it doesn't matter which number for which letter)

4^2+3^2=c^2

16+9=c^2

25=c^2

[tex]\sqrt{25}[/tex] = [tex]\sqrt{c}[/tex]

c=25

My explanation is kinda confusing, sorry about that.

Answer:

[tex]m || n \\ (4x - 11) + (5x + 20) = 180 \\ 9x + 9 = 180 \\ 9(x + 1) = 180 \\ x + 1 = 20 \\ x = 19 \\ \\ then \\ (4x - 11) = (2y + 19) \\ (4 \times 19 - 11) = (2y + 19) \\ 65 = 2y + 19 \\ 2y = 46 \\ y = 23[/tex]

An isosceles triangle is a triangle that has two sides and thus two angles the same amount. Triangles have 180 degrees, so if we subtract:

180 - 132 = 48, we do not have enough degrees to have a second 132° angle That leaves the 48° to be the angles to be split:

48 / 2 = 24°

So your answer is going to be 130-25-25 angle triangle.

*Just for reference, an example of an isosceles triangle having two possible answers? Let's say the given degree is 50o. Thus it could be one of the mirrored degrees (80-50-50), or it could be the non-mirrored angle (50-65-65)

Answer:

The other two angles of isosceles triangle will be 24° each.

Step-by-step explanation:

An isosceles triangle is a triangle that has two sides and thus two angles opposite to the equal sides will be same .

Also Triangles have sum of all angle to be 180° , so if we subtract the given angle we get

180° - 132° = 48°,  

So the total  sum of angle remaining for other two angles  will be of 48°

Therefore the sum of each angle will be

48° / 2 = 24°

So all angles of the  isosceles triangle will be 132°-24°-24°angle triangle.

Answer:

Less than 14.

Step-by-step explanation:

Since we are multiplying 14 by 3/7, and 3/7 < 1, then 14 must be less than 14, because we're multiplying it by a fraction. Therefore, when we multiply by 3/7, we are essentially turning 14 into 3 parts out of 7 parts out of 14, or 6.

Answer:

A, [tex]\frac{5\sqrt{74}}{74}[/tex]

Step-by-step explanation:

Cosine of an angle is equal to the adjacent side of that angle over the hypotenuse of the triangle. Since the adjacent side is 5, and the hypotenuse is √74, the value is 5 / √74.

However, we can't have radicals (square roots) in the denominator, so we multiply the top and bottom by √74 so that the radical goes on the top.
