Answer:

50.24

Step-by-step explanation:

the formula to find a circle is radius times radius times pi, which equals 3.14.      The radius is 2 so radius times radius would be 4. Now u times it by pi so 4 times 3.14 equals 12.56. Do this times ur hight wich is times 4 and u come up with 50 .24

Answer:

4(3x-y)

Step-by-step explanation:

Given:

[tex]\displaystyle \large{3(3x-y)-(y-3x)}[/tex]

To factor this kind of expression, first, find the common factor.

[tex]\displaystyle \large{3(3x-y)-(-3x+y)}\\\displaystyle \large{3(3x-y)+(3x-y)}[/tex]

Notice that in the expression, we have both same (3x-y). Therefore, (3x-y) is our factor.

Let u = 3x-y

[tex]\displaystyle \large{3u+u}\\\displaystyle \large{4u}[/tex]

Change u back to 3x-y:

[tex]\displaystyle \large{4(3x-y)}[/tex]

Therefore, the factored expression is 4(3x-y).

If x = 1/4 and Y = 3/7

Evaluate the following expression: 7x - 4y

[tex] \\ [/tex]

[tex] \rm{7 ( \frac{1}{4}) - 4( \frac{3}{7} ) } \\ [/tex]

[tex] \rm { \orange{7 \times \frac{1}{4} }} - 4 \times \frac{3}{7} \\ [/tex]

[tex] \rm{ \frac{7}{4} - \orange{ 4 \times \frac{3}{7 }} } \\ [/tex]

[tex] \rm \orange{ \frac{7}{4} - \frac{12}{7} } \\ [/tex]

[tex] = \small{\boxed{{\sf{ \frac{1}{28} }}}}[/tex]

Therefore, the answer is 1/28.

Answer:

Step-by-step explanation:

[tex]\text{Substitute the values of x and y in the expression}[/tex]

[tex]7x - 4y = 7*\dfrac{1}{4}-4*\dfrac{3}{7}[/tex]

            [tex]\sf =\dfrac{7}{4}-\dfrac{12}{7}\\\\ [LCM \ of 4 \ and \ 7 = 28]\\\\ =\dfrac{7*7}{4*7}-\dfrac{12*4}{7*4}\\\\=\dfrac{49}{28}-\dfrac{48}{28}\\\\=\dfrac{1}{28}[/tex]

Answer:

Step-by-step explanation:

Tan 70 = 16/x

x = 16/tan70

x = 5.824 to the nearest thousandth

tan 41 = 16 / (x + y)

tan 41 = 16 /(5.8235 + y)

tan41(5.8235 + y) = 16

5.8235 + y = 16/ tan41

y = (16/ tan41) - 5.8235

y = 12.582 to the nearest thousandth

Answer:

the answer= y=5−x/2

Answer: [tex]y=-\frac{1}{2} x+5[/tex]

Step-by-step explanation:

We need to isolate y by itself

Step 1) Subtract 3x from both sides

[tex]3x+6y=30\\3x-3x+6y=30-3x\\6y=30-3x[/tex]

Step 2) Divide both sides by 6 to isolate y

[tex]6y=30-3x\\\frac{6y}{6} =\frac{30}{6}-\frac{3x}{6} \\y=5-\frac{1}{2}x[/tex]

Step-by-step explanation:

If Mr. Swift is traveling from his house to the history museum. The number of meters will he travel to the museum is 6,400 meters.

Given:

Distance=6.4 Kilometres

Hence:

1 kilometre= 1,000 meters

Number of meters=6.4 kilometres x 1,000 meters

Number of meters =6,400 meters

Therefore the number of meters will he travel to the museum is 6,400 meters.

Answer:

1. b/c        4. c/b

2. a/c       5. c/a

3. b/a       6. a/b

Step-by-step explanation:

sin theta = opposite/hypotenuse    = b/c

cos theta = adjacent/hypotenuse   = a/c

tan theta= opposite/adjacent          = b/a

For the rest, you just flip it:

csc theta  = c/b

Answer:

94 Wins

Step-by-step explanation:

Here we need to find the mean, to do this we add up all the values then divide the sum by how many values we started out with.

97 + 103 + 92 + 95 + 84 = 471

471 / 5 = 94.2

since we got a decimal we can round to find an exact number; since the decimal is under .5 we will round down, 94

So 94 wins would be the correct answer. Hope this helped!

Considering the situation described, it is found that Ashton was born on August 8.

It means that August 31 was on Monday, hence the same is valid for August 24, August 17, August 10 and August 3.

Hence, the first Saturday was August 1, and the second August 8.

Step-by-step explanation:

It has two equal length sides and is a right triangle

Any number greater than 3.

Step-by-step explanation:

To find the answers to this question, start by solving the inequality for x.

2x - 1 > x + 2

x - 1 > 2

x > 3

Using this, we now know that any number that is greater than 3 would work for this inequality.

Answer:

42 degrees

Step-by-step explanation:

The measure of the indicated angle is 42 degree.

An isosceles triangle has two equal sides regardless of the direction the apex (or peak) of the triangle points. Some useful information regarding isosceles triangles is as follows:

We have a Triangle.

Then, using Isosceles Triangle Theorem

Angles opposite an isosceles triangle's equal sides are also equal.

According to the isosceles triangle theorem, if two sides of a triangle are congruent, then the angles opposite the congruent sides are likewise congruent.

So, x= 42 degree.

Answer:

249 centimeters squared

Step-by-step Explanation:

The area of the rectangle: l x w, where l is the length and w is the width.

= 15.5 x 18

= 279

Area of the smaller rectangle: l x w, where l is the length and w is the width.

= 4 x 7.5

= 30

We do not need this 30.

Area of the shaded region:

= 279 - 30

Answer:

(-1,-3) and (1,-1)

Sometimes you give the solutions as just the x.

x = -1 and x = 1

Step-by-step explanation:

The two curvy pieces are f(x) and the straight line is g(x). The solutions are where the two graphs intersect. There are two points where this happens: (-1,-3) and (1,-1).

Sometimes your teacher, the text or the course just wants you to give the answer as the x where it happens. The graphs intersects where x=-1 and x=1

Step-by-step explanation:

Substitute y = 4 into the first equation:

Answer:

9

Step-by-step explanation:

Since Area = L × W

Thus,

Area = (x + 2)(2x - 5) = 56

x^2 +4x - 5x - 10 = 56

x^2 - x - 10 = 56

x^2 - x - 66

Using the quadratic formula:

a = 1

b = - 1

c = - 66

Solving:

[tex]\frac{x = (-b) +/- sqrt(b^2 - 4ac)}{2a}[/tex]

[tex]\frac{x = 1 + /- sqrt(1^2 - 4(1)(-66)}{2(1)}[/tex]

[tex]\frac{1 +/- sqrt (265)}{2}[/tex]
