Have a great rest if your day!

Answer:

The answer is 9.79

Step-by-step explanation:

4.45 x 2.2 = 9.79

Answer:

12 cm²

Step-by-step explanation:

The base face of the trriangular prism is a triangle with base (of the triangle) 8 cm and height (of the triangle) 3 cm.

area of triangle = base × height / 2

area = (8 cm)(3 cm)/2

area = 12 cm²

Answer:

105 shifts

Step-by-step explanation:

Hourly net rate of pay = $12

1 shift = 8 hours

⇒ net pay per shift = $12 × 8 = $96

Total cost  = tuition + residence + books

                  = $4500 + $4800 + $700

                  = $10,000

To calculate how many shifts Joanne needs to work, divide the total cost by the pay per shift and round it up:

Number of shifts = total cost ÷ net pay per shift

                            = $10,000 ÷ $96

                            = 104.1666666...

                            = 105 shifts

Note: we need to round up, as if Joanne works 104 shifts, she will earn $9,984 which is not quite enough to pay for tuition, residence and books.

Question #1

Question #2

Answer:

-8<-4

Step-by-step explanation:

Given expressions:

[tex]3x-2\\4x+4[/tex]

(a)

When x = 0:

[tex]=3(0)-2[/tex]

[tex]=-2[/tex]

[tex]=4(0)+4\\=4[/tex]

Answer:

-2<4

(b)

When x = -6

[tex]=3(-6)-2\\=-18-2\\=-20[/tex]

[tex]=4(-6)-2\\=-24-2\\=-26[/tex]

Answer:

[tex]-20 > -26[/tex]

(c)

When x = 5:

[tex]=3(5)-2\\=15-2\\=13[/tex]

[tex]=4x+4\\=4(5)+4\\=20+4\\=24[/tex]

Answer:

13<24

(d)

When x = -2:

[tex]=3(-2)-2\\=-6-2\\=-8[/tex]

[tex]=4x+4\\=4(-2)+4\\=-8+4\\=-4[/tex]

Answer:

-8<-4

Answer:

B

Step-by-step explanation:

using the rule of exponents

[tex]x^{\frac{a}{b} }[/tex] = [tex]\sqrt[b]{x^{a} }[/tex]

then

[tex]x^{\frac{1}{8} }[/tex] ( with a = 1 , b = 8 )

= [tex]\sqrt[8]{x}[/tex]

Answer:

C

4296 - 80% = 859.2 + 4297 = 5155.2

Rounded up to the nearest answer

Answer:

5

Step-by-step explanation:

206 = 0

26 = 1

3 = 2-higher

206+26=232+3=235

3/235

6/470

235 is about 200

5/400

Answer:

144pi

Step-by-step explanation:

The formula for the volume of a cylinder is base*height

The base of a cylinder is a circle, so it's pi*r^2

r = 6, so pi*r^2 is 36pi

height is 4 so 36pi*4 is 144pi

Answer:

144pi

Answer:

All real numbers

Step-by-step explanation:

[tex]2p+3 > 2(p-3)[/tex]

1. Distribute the 2 on the right side of the inequality.

[tex]2p+3 > 2p-6[/tex]

2. Cancel out the 2p on both sides of the equation since they are equal.

[tex]3 > -6[/tex]

The statement above is always true, meaning that p can be all real numbers, therefore having all real solutions.

Answer:

Step-by-step explanation:

1. angle y will correspond to angle Q.

2. They are not similar since the side Q R has the line going 2 squares and the corresponding side YZ has the line passing three squares

Answer:

Fractions that are less than 1/2 but more than 0 are closer to 0 than to 1.

Step-by-step explanation:

Another explanation of this is anything that is less than 0.5 is closer to zero.

Hope this helps! Have an amazing day! :D

Answer:

Step-by-step explanation:

The arithmetic sequence is 6, 10, 14 , 16

First term (a) = 6

Subtract the first term from the second term:

Subtract the second term form the third term:

Subtract the third term from the Fourth term:

Here, You will notice that each time you move from one number to the next one it increases by four. So, the difference between one and the next term is four.

So,

Next two terms are:

⟶ 16 + 4 = 20

⟶ 20 + 4 = 24

Hence,

Step-by-step explanation:

Solution :-

D( common difference ) = a2 - a1

D = 10 – 6

D = 4

Next two terms ,

16 + D ; 16 + 4 = 20

20 + D ; 20 + 4 = 24

Answer:

110/90

Step-by-step explanation:

There are infinite ways to write this, but the one above is one of the ways.

Answer:

There are many ways to write 11/9.

We can find equivalent fraction like 22/18 or 110/90.

We can turn it into a decimal (1.222222 the 2 repeats)

or we can turn it into a percent of 12.2222 (the 2 repeats)

Answer:

215.7176 ft^2

Step-by-step explanation:

One step at a time.

First, let's figure out what the square area is.

12 ft by 15 ft = A=wl=15·12=180 ft^2

Now we add the tringle area: K = 35.7176 ft2

Add: 215.7176 ft^2

Sides:

a = 12 ft

b = 7.93725 ft

c = 9 ft

Other:

P = 28.9373 ft

s = 14.4686 ft

K = 35.7176 ft2

r = 2.46863 ft

R = 6 ft

Agenda:

A = angle A

B = angle B

C = angle C

a = side a

b = side b

c = side c

P = perimeter

s = semi-perimeter

K = area

r = radius of inscribed circle

R = radius of circumscribed c

The two angles form a straight line of 180 degrees.

This means they add to 180

115 + (4n-5) = 180

4n+110 = 180

4n = 180-110

4n = 70

n = 70/4

n = (35*2)/(2*2)

n = 35/2 is the answer as a fraction

n = 17.5 is the answer in decimal form

Answer: See below

Step-by-step explanation:

[tex]$$Given that,Height of ball hit by Phil,$$\begin{aligned}f(t) &=(-16 t-2)(t-2) \\&=-16 t^{2}-2 t+16 \times 2 t+4 \\&=-16 t^{2}+30 t+4\end{aligned}[/tex]

[tex]$$Part 1 \\ From the graph $B$ all hit by the John hits the court at $t=1 \mathrm{sec}$After hitting the ground position will be zero.Then.$$\begin{aligned}0 &=-16 t^{2}+30 t+4 \\& \Rightarrow t=2 \sec \text { or } \mathrm{t}=-\frac{1}{8}\end{aligned}$$Time cannot be negative, so the accepeted value is $2 \ \mathrm{sec}$.That is after $2 \sec$ the ball hit by Phill will reach the ground \\Therefore, the ball hit by John will hit the court first at $t=1 \sec$[/tex]

[tex]$$Part 2 \\Maximum height reached by the Phill's ball,$$f_{\max }=-16 \times\left(\frac{15}{16}\right)^{2}+30 \times \frac{15}{16}+4=18.06 \mathrm{ft}$$From the graph, the maximum height reached by John's ball is $6.2 \mathrm{ft}$ $\underline{\text { So }}$ Phil's tennis ball reach a higher maximum than John's tennis ball[/tex]

[tex]$$Part 3 \\The maximum height reached by the Phill's ball,$$f_{\max }=-16 \times\left(\frac{15}{16}\right)^{2}+30 \times \frac{15}{16}+4=18.06 \mathrm{ft}=18 \mathrm{ft}$$[/tex]
