subtract 2 1/5 - 5/6

Answer:

234 meters squared

Step-by-step explanation:

Add 3m on either side of the 15 to get 21

2(21x3)=2(63)=126

2(18x3)=2(54)=108

126+108=234

Answer:

The sum is 6

Step-by-step explanation:

Given

[tex]Vertices: (0,1), (3,4), (4,3), (3,0)[/tex]

[tex]Perimeter: a\sqrt{2} + b\sqrt{10}[/tex]

Required

[tex]a + b[/tex]

The first step is to name each points, as follows

[tex]A: (0,1)\\B: (3,4)\\C: (4,3)\\D: (3,0)[/tex]

Next is to calculate the distance between each consecutive point

We'll calculate the distance AB, BC, CD and DA

Distance between points is calculated as thus;

[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

Calculating distance AB

[tex]A: (0,1)\\B: (3,4)[/tex]

Here,

[tex]x_1 = 0; x_2 = 3[/tex]

[tex]y_1 = 1; y_2 = 4[/tex]

[tex]AB = \sqrt{(0 - 3)^2 + (1 - 4)^2}[/tex]

[tex]AB = \sqrt{(- 3)^2 + (-3)^2}[/tex]

[tex]AB = \sqrt{9+9}[/tex]

[tex]AB = \sqrt{18}[/tex]

Expand 18 as 9 * 2

[tex]AB = \sqrt{9 * 2}[/tex]

Split surds

[tex]AB = \sqrt{9} * \sqrt{2}[/tex]

Take square root of 9

[tex]AB = 3 * \sqrt{2}[/tex]

[tex]AB = 3 \sqrt{2}[/tex]

Calculating distance BC

[tex]B: (3,4)\\C: (4,3)[/tex]

Here,

[tex]x_1 = 3; x_2 = 4[/tex]

[tex]y_1 = 4; y_2 = 3[/tex]

[tex]BC = \sqrt{(3 - 4)^2 + (4 - 3)^2}[/tex]

[tex]BC = \sqrt{(-1)^2 + (1)^2}[/tex]

[tex]BC = \sqrt{1 + 1}[/tex]

[tex]BC = \sqrt{2}[/tex]

Calculating distance CD

[tex]C: (4,3)\\D: (3,0)[/tex]

Here,

[tex]x_1 = 4; x_2 = 3[/tex]

[tex]y_1 = 3; y_2 = 0[/tex]

[tex]CD = \sqrt{(4 - 3)^2 + (3 - 0)^2}[/tex]

[tex]CD = \sqrt{(1)^2 + (3 )^2}[/tex]

[tex]CD = \sqrt{1 + 9}[/tex]

[tex]CD = \sqrt{10}[/tex]

Calculating distance CD

[tex]D: (3,0)\\A: (0,1)[/tex]

Here,

[tex]x_1 = 3; x_2 = 0[/tex]

[tex]y_1 = 0; y_2 = 1[/tex]

[tex]DA = \sqrt{(3 - 0)^2 + (0 - 1)^2}[/tex]

[tex]DA = \sqrt{(3)^2 + (- 1)^2}[/tex]

[tex]DA = \sqrt{9 + 1}[/tex]

[tex]DA = \sqrt{10}[/tex]

At this point, the perimeter can then be calculated

[tex]Perimeter = AB + BC + CD + DA[/tex]

[tex]Perimeter = 3 \sqrt{2} + \sqrt{2}\ + \sqrt{10} + \sqrt{10}[/tex]

[tex]Perimeter = 4 \sqrt{2} + 2\sqrt{10}[/tex]

From the given parameters;

[tex]Perimeter: a\sqrt{2} + b\sqrt{10}[/tex]

This implies that;

[tex]a\sqrt{2} + b\sqrt{10} = 4 \sqrt{2} + 2\sqrt{10}[/tex]

By comparison;

a = 4 and b = 2

Hence;

[tex]a + b = 4 + 2[/tex]

[tex]a +b = 6[/tex]

Answer:

$15

Step-by-step explanation:

Let bushes = b and trees = t.

We can write:

12b + 15t = 600 (Equation 1)

8b + 20t = 680 (Equation 2)

24b + 30t = 1200 (Equation 3 -- Multiply Equation 1 by 2)

24b + 60t = 2040 (Equation 4 -- Multiply Equation 2 by 3)

30t = 840 (Subtract Equation 3 from 4)

t = 28 (Divide by 30)

12b + 15 * 28 = 600 (Substitute t = 28 into Equation 1)

12b = 180 (Simplify)

b = 15 (Divide by 12)

Answer:

B. Tom wants to save $846, he already has $87, and he deposits $23 each month, M.

Step-by-step explanation:

$846 = $87 + $23M

The $846 represents the amount that he wants to save. $23M represents how much money he wants to deposit every M months. $87 represents the amount that he has already deposited (the constant).

And so, the correct answer will be B. Tom wants to save $846, he already has $87, and he deposits $23 each month, M.

Answer:

805

Step-by-step explanation:

Scaling up by a factor of ten means that you must multiply the original number by 10. Because 10 has one zero, the best way to figure this out is just moving the decimal to the right ONCE (just like there is ONE zero)! This gives us 805.

Answer:

Multiplication property of equality

Step-by-step explanation:

Given

Step 4: b = -27/8

Required

Which property justifies it?

First, it should be noted that step 4 is a result of step 3

When step 3 is multiplied by 3/8 on both sides, we have step 4;

i.e.

[tex]\frac{8}{3b} = -9[/tex]

[tex]\frac{8}{3b} * \frac{3}{8} = -9 * \frac{3}{8}[/tex]

[tex]b = -9 * \frac{3}{8}[/tex]

[tex]b = \frac{-9 * 3}{8}[/tex]

[tex]b = \frac{-27}{8}[/tex]

The property that allows 3/8 be multiplied on both sides is referred to as the multiplication property of equality

Answer:

C. Both A & B

Step-by-step explanation:

Solve the equations given:

Equation A:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 11x and add 7 to both sides:

16x (-11x) - 7 (+7) = 11x (-11x) - 32 (+7)

16x - 11x = -32 + 7

Simplify. Combine like terms:

16x - 11x = -32 + 7

5x = -25

Isolate the variable, x. Divide 5 from both sides:

(5x)/5 = (-25)/5

x = -25/5

x = -5

Equation A is an answer choice.

Equation B:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, add 10 & subtract 2x from both sides:

-4x (-2x) - 10 (+10) = 2x (-2x) + 20 (+10)

-4x - 2x = 20 + 10

Simplify. Combine like terms:

-4x - 2x = 20 + 10

-6x = 30

Isolate the variable, x. Divide -6 from both sides:

(-6x)/-6 = (30)/-6

x = 30/-6

x = -5

Equation B is also an answer choice.

C. Both A & B is your answer.

[tex]\frac{1}{36}[/tex] chance

Step-by-step explanation:

Each time you roll a die, you have a [tex]\frac{1}{6}[/tex] chance of rolling a 3. It's even rarer to roll two 3s in a row, and to find a consecutive probability, we have to multiply the two probabilities. In this case, both probabilities are [tex]\frac{1}{6}[/tex].

[tex]\frac{1}{6}\cdot\frac{1}{6}=\frac{1}{36}[/tex]

Answer:

B. (2, 0)

Step-by-step explanation:

Step 1: Elimination (Subtract the 2 equations/add the 2 equations, one being negative)

b = 0

Step 2: Plug in b to get a

6a - 5(0) = 12

6a - 0 = 12

6a = 12

a = 2

Answer:

B.

Step-by-step explanation:

If you want to find a table with a proportional relationship, you are looking for one where the x-values and y-values increase at the same linear rate.

In Option A, the x-values increase steadily by 1 and then by 2, but the y-values jump around. The numbers are not proportional.

In Option B, every time an x-value is presented, the y-value is two times the value of x. So, this is a proportional relationship.

In Option C, it is true that for almost every time an x-value is presented, the y-value doubles the x-value, but when x is 0, y is 1. That is not a proportional relationship.

In Option D, it is the same thing as Option A.

So, your answer is Option B.

Hope this helps!

In general for a rectangle of dimensions w by h and a semicircle of diameter w we get an area:

A = wh + \frac 1 2 \pi (\frac w 2)^2

The halfs are because a semicircle is half a circle and a radius is half a diameter.

We're told

h = 1+ 3w

Substituting,

A(w) = w(1+3w) + \frac 1 2 \pi (\frac w 2)^2

Answer:

44

Step-by-step explanation:

The side-splitter theorem states that if a line intersects two sides of a triangle and is parallel to the third side of the triangle, it divides those two sides proportionally. This means that:

22/x = 10/20

Isolating x:

22*20 = 10*x

x = 22*20/10

x = 44

Answer:

Angles in a straight line ( linear pair)= 180°

Answer:

5 cm

Step-by-step explanation:

Area of 3 cm circle

A = pi r^2 = pi *3^2 = 9pi

Area of 4 cm circle

A = pi r^2 = pi *4^2 = 16pi

The area of the new circle is 16pi+9pi = 25 pi

25 pi = pi r^2

Divide each side by pi

25 = r^2

Take the square root of each side

sqrt(25) = sqrt(r^2)

5 = r

The radius is 5

Answer:

x= 3/2 = 1.5

Step-by-step explanation:

● 5(4x-10)+10x =4(2x-3)+2(x-4)

Simplify the products

● 5*4x-5*10+10x = 4*2x-4*3+2*x-2*4

● 20x-50+10x = 8x-12+2x-8

Add the terms that don't contain x with each other

●20x-50+10x = 8x-20+2x

Add 20 in both sides

●20x-50+20+10x = 8x-20+2x+20

●20x-30+10x = 8x+2x

Add together the terms that contain x

●30x -30 = 10x

Add -10x in both sides

●30x-30-10x = 10x-10x

● 20x -30 = 0

Add 30 in both sides

● 20x-30+30 = 30

● 20x = 30

Divide both sides by 20

●20x/20 = 30/20

● x= 30/20

● x= 3/2

● x= 1.5

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (- 4, 3) and r = 7 , thus

(x - (- 4))² + (y - 3)² = 7² , that is
