Chris can read 50 pages of a book in 1 ½ hours. Based on this rate, how many pages will he read in 4 ½ hours?

Answer:

x<-3

Step-by-step explanation

2x+5<x-1/4

in x-1/4 you should remove 4 so you should multiply 4 from both side

8x+20<x-1

subtract x from both side

8x-x<-1-20

7x<-21

divided by 7 from both side

x<-3 answer is x<-3

Answer:

Triangle 1: isosceles

Answer:

3544 people

Step-by-step explanation:

We can start by representing this as an exponential function, in the form [tex]y=a(b)^x[/tex]

2000 will be our a, or our initial value. We must convert our multiplier, 4.5% to a decimal, which is 1.045. 13 is our input since it's our number of years where we want to find the population. Now that we have our variables, lets make an equation.

[tex]y=2000(1.045)^13[/tex]

PEMDAS states that we first do exponents, so lets raise 1.045 to the 13th power.

[tex]y=2000(1.77219609724)[/tex]

Now we multiply by 2000!

[tex]y= 3544.39219448[/tex]

Rounded to the nearest whole number is 3544. Therefore, there will be 3,544 people living in the town in 13 years.

Answer:

27

Step-by-step explanation:

[tex] \frac{2 {}^{3} \times 3 {}^{4} \times 4}{3 \times 32 } [/tex]

Make everything in the form of exponet.

[tex] \frac{ {2}^{3} \times {3}^{4} \times {2}^{2} }{3 {}^{1} \times 2 {}^{5} } [/tex]

Use the rule.

[tex]a {}^{m} \times {a}^{n} = a {}^{m + n} [/tex]

[tex] \frac{2 {}^{3 + 2} \times {3}^{4} }{3 \times {2}^{5} } [/tex]

[tex] \frac{2 {}^{5} \times {3}^{4} }{3 \times {2}^{5} } [/tex]

Cancel out like Terms.

[tex] \frac{3 {}^{4} }{3} [/tex]

Use the property

[tex] \frac{a {}^{m} }{a {}^{n} } = {a}^{m - n} [/tex]

So we have

[tex]3 {}^{4 - 1} = 3 {}^{3} [/tex]

[tex]3 {}^{3} = 27[/tex]

The total number of marbles in Marcel's collection is 50.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Marcelo has 6 red marbles in his marble collection. Red marbles make up 12% of all the marbles.

The number of marbles in Marcel's collection is calculated as,

12% of marbles = 6

1% of marbles = 6 / 12

100% of the marbles= ( 6 / 12) x 100

100% of the marbles = 50

Answer:

4.75 hours

Step-by-step explanation:

First you need to find the median of the two numbers. The fastest way to do it is to add 9.3 and 9.7 and divide by 2, which will give you 9.5. Since there's going to be two of them working, divide 9.5 by 2, and you get 4.75.

1/9.3 + 1/9.7 = 1/x

x=4.74789

If simplicity is to be applied,

³√-216 = -6

therefore -6³ = -216

Answer:

The slope-intercept form is written as y = mx+b, where m is the slope and b is the y-intercept (the point where the line crosses the y-axis). It's usually easy to graph a line using y=mx+b.

Step-by-step explanation:

Let ,

130° + y = 180° — ( i )

x + 107° + y = 180° — ( ii )

now ( i )

130° + y = 180°

y = 180° - 130°

y = 50°

now substituting value of y in equation ( i )

[tex]x + 107 + y = 180 \\ x + 107 + 50 = 180 \\ x + 157 = 180 \\ x = 180 - 157 \\ [/tex]

x = 23°

Answer:

-63

Step-by-step explanation:

-9 multiply by 7

Hey there!

-9r

= -9(7)

= -9 + -9 + -9 + -9 + -9 + -9 + -9

= -9 - 9 - 9 - 9 - 9 - 9 - 9

= -18 - 18 - 18 - 9

= -36 - 18 - 9

= -54 - 9

= -63

Thus, your answer is: -63

Fun fact!
2 negatives equals positive

2 positives equals positive

1 negative & 1 positive equals negative

1 positive & 1 negative equals negative

That’s why your result was a negative because you had 1 negative (-9) and 1 positive (7)

Good luck on your assignment & enjoy your day!

Step-by-step explanation:

There are several ways to find area of triangle from vertex coordinates, the easiest is: (x₁*(y₂-y₃) + x₂*(y₃-y₁) + x₃*(y₁-y₂)) / 2

Area = ((-1)*(-6 - -6) + (-6)*(-6 - 2) + (3)*(2 - -6)) / 2

Answer:

-13°

Step-by-step explanation:

Start at 15°

Subtract 33° -----> 15-33= -18°

It has warmed up by 5° (+5) -----> -18+5= -13°

Step-by-step explanation:

a) 3x + 5y = 8

4x - 3y = 1

• using the elimination method:

3x + 5y = 8 (×4)

4x -3y = 1 (×3)

12x + 20y = 32

12x -9y = 3

subract 12x from both equation:

20y - - 9y= 32 -3

20y +9y = 29

29y= 29

y= 29/29

y= 1

- substituting y= 1 in :

4x - 3y= 1

4x - 3(1) = 1

4x -3 = 1

4x = 1 + 3

x = 4/4

x= 1

b) 6p+ 4q = 20

5p - 2q = 6

• using the elimination method:

6p + 4q = 20

5p - 2q = 6 (×2)

6p + 4q = 20

10p - 4q = 12

add 4q + -4q to eliminate q.

6p+ 10p = 20+12

16p = 32

p = 32/ 16

p = 2

- subtituting p = 2 in :

5p - 2q = 6

5(2) -2q =6

10 -2q = 6

-2q = 6 - 10

q = -4 / -2

q = 2

Answer:

Question 1: C. 4 × 3 × 2 ×  [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]

Question 2: The volume is [tex]\frac{1}{12}[/tex] or 0.083333333

Question 3: The volume fo the solid figure is 234

Step-by-step explanation:

1. Volume of a rectangular prism = (length × width × height) cubic units

Length = 4 ×  [tex]\frac{1}{8}[/tex]

Width = 3 × [tex]\frac{1}{8}[/tex]

Height = 2 × [tex]\frac{1}{8}[/tex]

Volume = 4 ×  [tex]\frac{1}{8}[/tex] × 3 × [tex]\frac{1}{8}[/tex]  × 2 × [tex]\frac{1}{8}[/tex]

Volume = 4 × 3 × 2 ×  [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]

So the correct option is:

C. 4 × 3 × 2 ×  [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]  × [tex]\frac{1}{8}[/tex]

2.

We have to fold the shape into a rectangular prism, look at the picture

Volume of a right rectangular prism =  (length × width × height)

Length = [tex]\frac{1}{3}[/tex]

Width =  [tex]\frac{1}{3}[/tex]

Height = [tex]\frac{3}{4}[/tex]

Volume = [tex]\frac{1}{3}[/tex] ×  [tex]\frac{1}{3}[/tex]  ×  [tex]\frac{3}{4}[/tex]

Multiply [tex]\frac{1}{3}[/tex] times [tex]\frac{1}{3}[/tex] by multiplying numerator times numerator and denominator times denominator.

[tex]\dfrac{ 1 \times 1 }{ 3 \times 3 } \times \left( \dfrac{ 3 }{ 4 } \right)[/tex]

Do the multiplications in the fraction [tex]\dfrac{ 1 \times 1 }{ 3 \times 3 }[/tex]

[tex]\dfrac{ 1 }{ 9 } \times \left( \dfrac{ 3 }{ 4 } \right)[/tex]

Multiply [tex]\frac{1}{9}[/tex] times [tex]\frac{3}{4}[/tex] by multiplying numerator times numerator and denominator times denominator.

[tex]\dfrac{ 1 \times 3 }{ 9 \times 4 }[/tex]

Do the multiplications in the fraction [tex]\dfrac{ 1 \times 3 }{ 9 \times 4 }[/tex]

[tex]\frac{3}{36}[/tex]

Reduce the fraction [tex]\frac{3}{36}[/tex] to the lowest terms by extracting and canceling out 3

Fraction form: [tex]\frac{1}{12}[/tex]

or

Decimal form: 0.083333333

So the volume of the right rectangular prism is [tex]\frac{1}{12}[/tex]

3. Look at the picture with the solid figure labeled

We can think of this shape as two different prisms ( A and B)

Volume of A = 4.5 × 6 × 6.5 = 175.5

Volume of B = 3 × 3 × 6.5 = 58.5

Total volume of the whole figure = 175.5 + 58.5

175.5 + 58.5 = 234

So the volume of the solid figure is 234
