Answer:

20 yards squared.

Step-by-step explanation:

First, you should convert your units. Three feet make a yard, so 15 feet = 5 yards and 12 feet = 4 yards.

The area of a square is found by multiplying the length and width, so 5 yards x 4 yards = 20 yards.

Answer:

28 + 44 = 4(7 + 11)

Step-by-step explanation:

Step-by-step explanation:

Think of it this way what if an exponent had 1 so like 10^1

that still equals 10, and does not change anything, so you need to add one more to the exponent as the first number does not change how many types the number is multiplied. Hope this helps

Answer:

Angle 1 = 180°-99° (adj angles on a str line)

= 81°

Angle 2 = 99° (vert opp angles)

Angle 3 = 81° (vert opp angles)

Angle 4 = 99° (corr angles, a//b)

Angle 5 = 81° (corr angles, a//b)

Angle 6 = 99° (corr angles, a//b)

Angle 7 = 81° (corr angles, a//b)

Answer:

pizza yum

Step-by-step explanation:

Answer:

$0.80 per square inch

Step-by-step explanation:

To find the cost per every square inch, divide the total cost of the pizza by the inches of the pizza. The pizza is 20 square inches and costs $15.99. The cost for every inch of pizza would be $0.7995, but you can just round that to $0.80 ($15.99/20 = $0.7995).

The answer is 28/3, and in simplest form its 9 1/3

Answer:

4800

Step-by-step explanation:

4773

The 3 is the ones digit.

The 7 to the left of the 3 is the 10s digit.

The 7 (in bold) to the left of the other 7 is the hundreds digit.

1. Make all digits to the right of the hundreds digit 0.

4700

2. We need to find out if we end up with 4700 or 4800.

Since the digit just to the right of the hundreds digit is greater than 4 (it is the tens digit which is a 7), then the hundreds digit 7 must go up 1 to 8.

Answer: 4800

Answer:

x=15/19

Step-by-step explanation:

You have to start by multiplying the denominators by the numerators. I doesn't matter which you do first, as you can see, I chose to multiply the 6 by the 4x first.

Once that is completed, it is a simple matter of rearranging the equation so it begins with x=...

To do this, just subtract 5x and then divide by 19 on both sides to get the final fraction.

Answer:

M = C

BC = LM

B = L

Step-by-step explanation:

We can see that there are double lines between BC and LM, and a triple line curves at Angle B and Angle L.

We can conclude that:

A = K

B = L

C = M

C = K (NO)

BA = MK (NO)

M = C (YES)

BC = LM (YES)

B = L (YES)

     0.48

    0.240

+   0.6200

________

Answer:

19 x 10^12 = 1.9 x 10 ^13

23 x 10^8 = 2.3 x 10^9

23 x 10^7 = 2.3 x 10^8

19 x 10^-12 = 1.9 x 10^-11

23 x 10^-8 = 2.3 x 10^-7

23 x 10^-7 = 2.3 x 10^-6

Answer:

36/40 or 90%

Step-by-step explanation:

First convert it to a fraction, which in this case is 36/40.

To find the percentage, we need to find an equivalent fraction with the denominator of 100. Multiply both numerator & denominator by 100.

36/40 × 100/100

= (36 × 100/40) × 1/100 = 90/100

Therefore, the answer is 90%.

If you are using a calculator, simply enter 36÷40×100, which will give you 90 as the percentage.

Answer:

 y = -1/2x -3

Step-by-step explanation:

The line perpendicular to one with a slope of 2 will have a slope that is the negative reciprocal of 2, that is, -1/2. The given point is the y-intercept of the required line, so we can write its equation directly in slope-intercept form:

y = mx + b

where m is the slope (-1/2), and b is the y-intercept (-3). Your line is ...

 y = -1/2x -3

Answer:

0.8

Step-by-step explanation:

to find the decimal equivalent we must get the denominator to 100

to do that we must multiply it by 20, 4/5 * 20/20 is 80/100

80/100 is also 80%, which is also 0.80 (which can be simplified to 0.8)

Answer:

x = 26/45

Step-by-step explanation:

Answer:

Given Question

Solve for x :

[tex]\rm :\longmapsto\:\dfrac{3x - 5}{2} + x + \dfrac{2x - 3}{3} = \dfrac{5}{6} - \dfrac{3x}{2} [/tex]

[tex] \green{\large\underline{\sf{Solution-}}}[/tex]

Given expression is

[tex]\rm :\longmapsto\:\dfrac{3x - 5}{2} + x + \dfrac{2x - 3}{3} = \dfrac{5}{6} - \dfrac{3x}{2} [/tex]

[tex]\rm :\longmapsto\:\dfrac{3(3x - 5) + 6x + 2(2x - 3)}{6} = \dfrac{5 - 9x}{6}[/tex]

[tex]\rm :\longmapsto\:9x - 15 + 6x + 4x - 6 = 5 - 9x[/tex]

[tex]\rm :\longmapsto\:(9x + 6x + 4x) - 15 - 6 = 5 - 9x[/tex]

[tex]\rm :\longmapsto\:19x - 21 = 5 - 9x[/tex]

[tex]\rm :\longmapsto\:19x + 9x = 5 + 21[/tex]

[tex]\rm :\longmapsto\:28x = 26[/tex]

[tex]\rm :\longmapsto\:x = \dfrac{26}{28} [/tex]

[tex]\bf\implies \:x = \dfrac{13}{14} [/tex]

Consider LHS

[tex]\rm :\longmapsto\:\dfrac{3x - 5}{2} + x + \dfrac{2x - 3}{3}[/tex]

On substituting the value of x, we get

[tex]\rm \:  =  \: \dfrac{\dfrac{39}{14} - 5}{2} + \dfrac{13}{14} + \dfrac{\dfrac{13}{7} - 3}{3}[/tex]

[tex]\rm \:  =  \: \dfrac{39- 70}{28} + \dfrac{13}{14} + \dfrac{13 - 21}{21}[/tex]

[tex]\rm \:  =  \: \dfrac{ - 31}{28} + \dfrac{13}{14} - \dfrac{8}{21}[/tex]

[tex]\rm \:  =  \: \dfrac{ - 31 + 26}{28} - \dfrac{8}{21}[/tex]

[tex]\rm \:  =  \: \dfrac{ -5}{28} - \dfrac{8}{21}[/tex]

[tex]\rm \:  =  \: \dfrac{ -15 - 32}{84}[/tex]

[tex]\rm \:  =  \: - \: \dfrac{47}{84}[/tex]

Consider RHS

[tex]\rm :\longmapsto\: \dfrac{5}{6} - \dfrac{3x}{2} [/tex]

On substituting the value of x, we get

[tex] \rm \:  =  \: \dfrac{5}{6} - \dfrac{39}{28} [/tex]

[tex] \rm \:  =  \: \dfrac{70 - 117}{84}[/tex]

[tex] \rm \:  =  \: - \dfrac{47}{84}[/tex]

Hence, LHS = RHS

Hence, Verified.
