Answer:

1.72r²

Step-by-step explanation:

total Rectangle area = 4r*2r = 8r²

total circles area = 2(π r²) = 2*3.14*r² = 6.28r²

then:

the area of the shaded region:

= 8r² - 6.28r²

= (8-6.28)r²

= 1.72r²

Answer:

2r²(4 - π)

Step-by-step explanation:

The shaded area (A) is calculated as

A = area of rectangle - area of 2 circles

The rectangle has a length of 4r and a width of 2r , then

A = (4r × 2r) - (2πr²)

   = 8r² - 2πr² ← factor out 2r² from each term

    = 2r²(4 - π)

Answer:

Step-by-step explanation:

25.30*8% tax = 2.02 tax

total 25.30+2.02= $27.32

Answer:

$27.32

Step-by-step explanation:

Multiply $25.30 by 0.08 (8% is equal to 0.08)

2.024

Add 2.024 to $25.30

That would be 27.324

Round to the nearest hundredth

$27.32

Step-by-step explanation:

Answer:

4x+x=360 (whole equation)

x=72 (answer)

Step-by-step explanation:

Let the distance driven by Jason be x.

Selena drove four times as far.

Hence, distance Selena drove is 4x.

They drove 380 miles altogether.

Hence, 4x + x = 380

5x = 380

x = 72

Answer:

F(1) represents the first term of the sequence.

Step-by-step explanation:

Let us suppose the sequence function

[tex]F(n) = 16-3n[/tex]

We can find the first term of the sequence by substituting n=1 in the function sequence

[tex]F(1) = 16-3(1)[/tex]

        [tex]= 16-3[/tex]

        [tex]=13[/tex]

We can find the 2nd term of the sequence by substituting n=2 in the function sequence

[tex]F(2) = 16-3(2)[/tex]

        [tex]= 16-6[/tex]

        [tex]=10[/tex]

We can find the 3rd term of the sequence by substituting n=3 in the function sequence

[tex]F(3) = 16-3(3)[/tex]

        [tex]= 16-9[/tex]

        [tex]=7[/tex]

So the first three terms of the sequence is:

13, 10, 7...

As the common difference is the same.

i.e. d = 10-13 = -3, d = 7-10 = -3

Hence, it is an Arithmetic sequence.

As the first term is 13, which can be obtained by putting n=1 in the function sequence.

Therefore, from the above discussion, we can conclude that F(1) represents the first term of the sequence.

Answer:

457/100

Step-by-step explanation:

just move the decimal to the right twice and put a hundred underneath

Answer:

3/100=0.03.

second one.

60/10=6.

Answer:

see below

Step-by-step explanation:

just cross multiply:

10 (x) = 3 (100)

x = 300 / 10

x = 30

same as above, just cross multiply:

100 (x) = 60 (10)

x = 600 / 100

x = 6

Answer:

d=1

Step-by-step explanation:

distribute 0.5 through the parentheses

3.5d+2=7-1.5d

move variable to the left-hand side and change its sign

3.5d+1.5d+2=7

move constant to the right-hand side and change its sign

3.5d+1.5d=7-2

collect all like terms

5d=7-2

subtract the numbers

5d=5

divide both sides

d=1

Answer:

20

Step-by-step explanation:

first take out the cost of the cup 31.75-6.75=25

then divide by the cost of the refills 25/1.25=20

hope this helps :)

Step-by-step explanation:

V15 is rational ( contradiction method). V15=a/b (a and b are not common factor). squaring on both sides, we get, 15= a^2/b^2. 15b^2=a^2 (a=15c) b^2=15/a^2 (assume, a^2 =225c^2) 15b^2=225c^2 b^2=225c^2/15 b^2=15c^2 c^2=15/b^2 c =15/b. 15 divided both a and b which is a contradiction. ie, is irrational.

Answer:

[tex]2.89\ \text{s}[/tex]

0.11 seconds

[tex]37.4\ \text{m}[/tex]

Step-by-step explanation:

[tex]t_1[/tex] = Time taken by the pebble to hit the water

[tex]t_2[/tex] = Time taken by the sound to travel to the observer

[tex]t_1+t_2[/tex] = Time taken by the observer to listen to the splash after stone is thrown = 3 s

[tex]t_1=3-t_2[/tex]

a = g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]

[tex]u_s[/tex] = Speed of sound = 340 m/s

The distance traveled by the pebble

[tex]s=ut+\dfrac{1}{2}at_1^2\\\Rightarrow s=0+\dfrac{1}{2}\times9.81(3-t_2)^2\\\Rightarrow s=4.905(9+t_2^2-6t_2^2)[/tex]

Distance traveled by the sound

[tex]s=u_st\\\Rightarrow s=340\times t_2[/tex]

The distance traveled by the sound and the pebble is equal

[tex]4.905(9+t_2^2-6t_2)=340\times t_2\\\Rightarrow 9+t_2^2-6t_2=\dfrac{340}{4.905}t_2\\\Rightarrow 9+t_2^2-6t_2=69.32t_2\\\Rightarrow t_2^2-75.32t_2+9=0\\\Rightarrow t_2=\frac{-\left(-75.32\right)\pm \sqrt{\left(-75.32\right)^2-4\times \:1\times \:9}}{2\times \:1}\\\Rightarrow t_2=75.2,0.11[/tex]

Since [tex]t_1+t_2=3[/tex] the value of [tex]t_2[/tex] cannot be greater than 3.

So, time taken by the sound to reach the observer is 0.11 seconds.

Time taken by the pebble to hit the water is [tex]t_1=3-t_2=3-0.11=2.89\ \text{s}[/tex]

Depth of the well is [tex]s=340t_2=340\times 0.11=37.4\ \text{m}[/tex]

The +7 at the end effectively adds 7 to each y coordinate output, which is why the entire graph shifts up 7 units. For instance, a point like (1,2) moves to (1,9) after shifting up 7 units.

Side note: The function f(x)=⌈x⌉ is the ceiling function. It takes any decimal value and rounds it up to the nearest whole number. If you had an input like x = 2.01 then the output would be y = 3 even though 2.01 is closer to 2 than it is to 3.

Answer:

m = -48

Step-by-step explanation:

m - 11 = -59 (add 11 on both sides)

m = -48

Hope this helps!!

Answer:

m = -48

Step-by-step explanation:

m - 11 = -59

you add the 11 to both sides crossing it out from the left side and then you get an equation that looks like this.

m = -59 + 11

Now you can just solve it like a simple subtraction problem, -59 + 11 = -48
