Answer: This is so because, the circle does not totally cover the area defined by the four squares and this is evident in the workings below.

The area of a square is; Area = l²

Since each circle has area, A = 1 square unit.

Therefore,

Length of Each side of each square = 1 unit

This in turn is the radius of the circle given;

The area of the circle is therefore, Area = πr²

Area = (22/7) × 1²

Area = 3.142 square units

In essence, the area of the circle is less than 4 square units.

Answer:

  9.1 cm

Step-by-step explanation:

The law of cosines can be used to find the missing side.

  l² = m² +n² -2mn·cos(L)

  l² = 8² +2.8² -2(8)(2.8)cos(103°) ≈ 81.9178

  l ≈ √81.9178 ≈ 9.0508

The length of l to the nearest tenth centimeter is 9.1 cm.

Answer:

a = -10

Step by step:

put it in standard form

you get

a+10=0

a = -10

Answer:

a= -12

Step-by-step explanation:

write your line down your paper on the equal sign

than do SADMAP, (backwards PEMDAS) so in this case subtract -7

do that on both sides

-7 cancels out making it positive 7 + -17

add

you should get -10 than bring down a

and you get

A=-10

Answer:

Alicia

Step-by-step explanation:

First, convert the mixed fractions into improper fractions

Alicia

Distance: 5 1/2 = 11/2 = 5.5 miles

Time: 1 2/5 = 7/5 = 1.4 hours

Carlos

Distance: 8 1/8 = 65/8 = 8.125 miles

Time: 2 1/2 = 5/2 = 2.5 hours

Henry

Distance: 3 2/3 = 11/3 = 3.6 reoccuring miles

Time: 1 1/10 = 11/10 = 1.1 hours

Zoe

Distance: 4 2/3 = 14/3 = 4.6 reoccuring miles

Time: 1 3/10 = 13/10 = 1.3 hours

After that, divide the distance by the time

Alicia = 5.5 / 1.4 = 3.93 ( 3 s.f )

Carlos = 8.125 / 2.5 = 3.25

Henry = 3.6 re / 1.1 = 3.3 reoccuring

Zoe = 4.6 / 1.3 = 3.54 ( 3 s.f )

Looking at these answers, we determine which rate is the greatest

Alicia = 3.93

Carlos = 3.25

Henry = 3.3 re

Zoe = 3.54

Alicia hiked the highest rate.

Answer:

1) 5/1 is the slope, and 10 is the y intercept.

2) Inital amount is the y intercept, and 10 is the rate of change.

3) Should be easy from there! Just graph (0,10), and go up 5, right 1, and repeat.

Step-by-step explanation:

This is in slope intercept form! Where 5 is the slope, and 10 is the y intercept. The rate of change is another way of saying slope, and the inital amount is your starting value, or y intercept.

Answer:

-42/8

Step-by-step explanation:

Answer: -21/4 or 5 1/4

Step-by-step explanation:

to divide fractions, multiply by the reciprocal of the divisor

7/8*-6/1

then, just multiply the numbers to get -42/8. then, simplify by dividing both the numerator and denominator by 2. this will get -21/4

Answer:

its b

Step-by-step explanation:

this is just an addition to the great reply above.

[tex]\begin{array}{ccll}\$&tickets\\\cline{1-2}54&3\\x&2\end{array}\implies \cfrac{54}{x}=\cfrac{3}{2}\implies 108=3x\implies \cfrac{108}{3}=x\implies \boxed{36=x}[/tex]

Step-by-step explanation:

2 + (1^2 - 1 ) = 2

2 +( 2^2 - 1 ) = 5

5 + ( 3^2 - 1) = 28

28 + (5^2 - 1) = 52

Thus the next number would be 52

Answer: 37.5 acre

Step-by-step explanation: First, let's find out how much acre there would be if there were 3 parks. Since we know our basic multiplication, 1.25 x 3 is 3.75.  Next, we need to find out what 12.5 x 3 is. When you multiply 12.5 x 3 you get 37.5.

Answer:

I believe it's A) "In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality."

Step-by-step explanation:

I say this because that's essentially the first step when solving both an equation and inequality.

(In case you were wondering, the next step would be to divide -3 on both sides, in order to get x by its self.)

Hope this helps :)

The solution of the system of equations  2x+3y=9 and y=x+8 is x = -3 and y = 5.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the two equations are 2x + 3y = 9 and y = x + 8. The value of x and y is calculated as:-

2x + 3y = 9

y = x + 8

Solve the equations as;-

2x + 3y = 9

-2x + 2y  = +16

___________

      5y = 25

        y = 5

y = x + 8

x = 8 - 5

x = 3

Therefore, the solution of the system of equations  2x+3y=9 and y=x+8 is x = -3 and y = 5.

B. y = 9/2x + 36

Step-by-step explanation:

Find the negative reciprocal of the slope of the original line and use the point-slope formula  y − y 1 = m ( x − x 1 )  to find the line perpendicular to  2 x +9 y = − 30 .

y = 9 /2 x + 36                        PERPENDICULAR

Answer:

y=-x-3

I attached a file so you can plot the points on your own.

Answer:

Step-by-step explanation: First we need to figure out the slope. There are two ways:

First you need to find the slope with Δy/Δx. This will plug in as

-7 - (-6)/ 4 - 3. This will simplify to -1/1, then -1. So m = -1

Now we have the equation y = -1x + b. We need to find b.

In order to do that, we need to plug in one of the points. I'm using (3,-6) but you can use whatever point. Once we plug it in, we have -6 = -(3) + b. Solve for b and you get -3. So the final equation is y = -x - 3.

Like the slope intercept form, we need to find the slope, in which case is -1. Next, we can use one of the ordered pairs again to plug it into the equation

y -  [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex]), where [tex]y_{1}[/tex] is the y of the pair and [tex]x_{1}[/tex] is the x of the pair. You can use the other points too. The final equation once you plug it in is y -(-6) = -(x-3) or y + 7 = -(x - 4).

Hope this helps!
