A. 1/15
B. 1/10
C. 2/5
D. 3/5

Answer:

The answer is no solution

Step-by-step explanation:

-25x+175>225 AND 5x-83 >= -73

In order to solve for the first inequality you would need to combine like terms:

-25x > 225-175

= -25x > 50

Next you would divide by -25 however, wheneve dividing by a negative number you would switch the sign:

x < -2

Now for the next inequality you would combine like terms:

5x >= -73+83

= 5x >= 10

Now divide by 5 on each side:

x >= 2

In this scenario the inequality says AND

However, x can't be greater then two and less then -2 since 2 is greater then negative two. Therefore, the answer is NO SOLUTION

Step-by-step explanation:

White cube .... this is just a visualization/counting exercise

  all of the corners have 3 sides painted  = 8

  all of the edge-middle cubes have two sides painted = 12

  all of the middle sides have 1 side painted = 6

   the one cube in the dead middle has no paint = 1

                                8 + 12 + 6 + 1  = 27 cubes  

#2  Find the entire volume of the tank to be    large cylinder - small cylinder

      cylinder volume formula  = pi r^2 h

       pi (50^2) (75)  -  pi ( 20^2)(75) = 494800 cm^3  = 494.8 L

         If you pour 200 liters into the it will fill to

             200 / 494.8    *    75 cm = 30.3 cm high

Answer:To fill the rectangular prism, 432 cubes are needed.

Step-by-step explanation:

Given, the length of the prism is 9 inches.

The width of the prism is 4 inches.

The height of the prism is  inches.

Therefore, the volume of the rectangular prism is

= length × width × height

= 9 × 4 × 1.5 (inches)³

= 54 (inches)³

Again, the edge length of the cube is  inches.

Therefore, the volume of the cube is

= (edge length)³

= (0.5)³ (inches)³

= 0.125 (inches)³

Now, the number of cubes that can be fitted inside the rectangular prism is = (volume of the rectangular prism) / (volume of the cube)

=

= 432

Answer:

The cubes required to fill the prism are 1584.

Step-by-step explanation:

so,

The volume of the prism is:

  volume = length x width x height

  volume = 9 in x 4in x 11/2 in => 198 in³

The volume of the cube is:

 volume =  edge length x  edge length x edge length

 volume = (1/2 in.) x ( 1/2 in.) x (1/2 in.)  => 1/8 in³

Number  of cubes needed = volume of the prism/volume of a single cube

Number cubes needed =  198 in³ / (1/8 in³)

Number of cubes needed = 1584

Therefore to fill the rectangular prism, 1584 cubes are needed.

Answer:

x+3 is the answer to this problem.

Step-by-step explanation:

If x > 5, then x + 3 is positive, so we can simplify the absolute value expression |x + 3| by removing the absolute value brackets and keeping the expression inside them:

|x + 3| = x + 3

Therefore, if x > 5, the simplified form of |x + 3| is just x + 3.

Step-by-step explanation:

Rise over run is the slope, m

m=2/5

a)  the slope is 2/5 = .4 which is below the boundary guideline.  So no this is not with in carpenter's guidelines

b) the image below show a line with slope 2/5 but with intercept 3

c) the stairs can be draw on the line with rise 2 run 5   from the line.  see image

d)equation is in image

2.

a) count the squares

horizontal distance =3

vertical distance =3

b)  slope is vertical distance over horizontal distance  so m= 3/3 =1

Answer:

4.44 cm²

Step-by-step explanation:

We can find the area of the outlined triangle by plugging its dimensions into the triangle area formula.

[tex]A = \frac{1}2 \times \text{base} \times \text{height}[/tex]

[tex]A = \frac{1}2 \times 6 \times 1.48[/tex]

[tex]\boxed{A = 4.44 \text{ cm}^2}[/tex]

Answer:

The second choice ([tex]x + y[/tex])

Step-by-step explanation:

If x = [tex]-\frac{5}{6}[/tex] and y = [tex]\frac{4}{3}[/tex], then we can insert those in for [tex]x[/tex] × [tex]y[/tex].

To determine if this will have a positive outcome, we don't even need to solve! We know that a negative multiplied by a positive will result in a negative product.

Therefore, this is not the correct answer.

Looking at the second choice, [tex]x + y[/tex] we can insert our numbers in for [tex]x[/tex] and [tex]y[/tex]:

The outcome of the two is a positive, marking it the correct answer.

Even though we already know the answer, we can still check the other choices to be sure.

The outcome of this is a negative, meaning it is incorrect.

For the last choice, we can once again insert the fractions in for [tex]x[/tex] and [tex]y[/tex]:

[tex]-\frac{5}{6} - \frac{4}{3} =-\frac{13}{6}[/tex]

This product is once again a negative, meaning it is incorrect.

Therefore, the second choice is the correct answer.

_5_ × _5_ × _5_

hence the answer is:

5 × 5 × 5 = 125

Answer:

Y=30x + 60

Step-by-step explanation:

Because most of the students time of doing a test is 90 minutes and 15x isn't the answer so, anything with 15x is not the answer.

To determine the equation of the line of fit, we need more information about the data and the line that was created. The equation of a line is typically represented as:

y = mx + b

Where:

y is the dependent variable (in this case, the grades earned on the test),

x is the independent variable (in this case, the amount of time spent studying),

m is the slope of the line, and

b is the y-intercept of the line.

Without additional information or the actual data points, it is not possible to determine the exact equation of the line of fit. The provided options (y = 15x + 60, y = 15x + 30, y = 30x + 60, y = 30x + 30) represent different possible equations based on the given information. However, without further context or calculation, it is not possible to determine which equation is correct.

Answer:

0

Explanation:
If the spinner has 4 green sections in a circle and you spin it 24 times, the best prediction for the number of times it will land on yellow is 0. Since there are no yellow sections mentioned, it is unlikely for the spinner to land on yellow.

Answer: 0

Step-by-step explanation:

There's no yellow, so it's not possible to spin yellow.

(0/4)*24=0

Answer:

5%

Step-by-step explanation:

The formula for calculating simple interest is:

Interest = Principal × Rate × Time

Where:

Interest is the amount of money earned as interest

Principal is the initial amount of money deposited

Rate is the interest rate (expressed as a decimal)

Time is the duration for which the money is invested or the time period over which interest is calculated

In this scenario, the principal amount is $50,000, and the interest earned is $2,500. The time period is given as 1 year.

We can rearrange the formula to solve for the rate:

Rate = Interest / (Principal × Time)

Plugging in the given values:

Rate = $2,500 / ($50,000 × 1)

The calculation simplifies to:

Rate = $2,500 / $50,000

Dividing $2,500 by $50,000 gives us the decimal value of the interest rate:

Rate = 0.05

To express the interest rate as a percentage, we multiply the decimal value by 100:

Rate = 0.05 × 100

Rate = 5%

Therefore, the interest rate for the savings account is 5%.

Answer:

Interest Rate = 5%

Step-by-step explanation:

Principal = $50, 000

Rate = ?

Time = 1 yr

S.I = PRT/100

2,500/1 = 50,000 × R × 1/100

50,000R = 2,500 × 100

50,000R = 250,000

50,000R/50,000 = 250,000/50,000

R = 5 %
