Answer:

268 increased by 75% of its value = 469

Step-by-step explanation:

hope this helps :))

The number when 268 is increased by 75%​ will be 469.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Let 'n' be the increased number. Then the equation is given as,

75% = [(n - 268) / 268] x 100

Simplify the equation, then we have

0.75 = (n - 268) / 268

n - 268 = 201

n = 201 + 268

n = 469

The number when 268 is increased by 75%​ will be 469.

[tex]volume \: = base \: area \: \times height[/tex]

[tex]volume = ( \frac{3}{4} \times \frac{1}{2} ) \times \frac{5}{8} \\ [/tex]

[tex]volume = \frac{3}{8} \times \frac{5}{8} \\ [/tex]

[tex]volume = \frac{15}{8} \\ [/tex]

Answer:

0.23

Step-by-step explanation:

The equation for finding the volume of a cube is

length x width x height

so you need to multiply 5/8 by 1/2.

This will give you 5/16.

Now multiply 5/16 by 3/4.

This will give you 15/64 , which in decimal form will be your answer 0.23

Answer:

I think it is E 3000

because area of a triangle is

1\2 base * height

base = BC = 120

height = AH = 100

120\2 = 60

60 * 100 = 6000

6000\2 = 3000

Answer:

$79.17

Step-by-step explanation:

91.00 x 0.13= 11.83 (the discount)

91.00-11.83= $79.17 (the sale price)

Answer: $71.17

Step-by-step explanation: If 91 is the original price and the discount rate is 13%, 13% of 91 is being taken off and 87% is remaining, to find the 87% that's remaining multiply the original (91) by the the remaining percent(87%).91 x .87=71.17

87%-->.87

87x.01=.87

To find the decimal form of a percentage multiply the percentage by .01.

Like terms are those terms that are having the same variables and order. The simplified form of the given equation 7z+2=8+2z+1z is 4z=6.

Like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

The given equation to us is 7z+2=8+2z+1z, simplifying the equation we will get,

[tex]7z + 2 = 8 + 2z + 1z\\\\\text{Bring the like terms on the same side of the equation}\\\\7z -2z-1z = 8 -2\\\\7z-3z=6\\\\4z = 6[/tex]

Hence, the simplified form of the given equation 7z+2=8+2z+1z is 4z=6.

Take a fixed gap and draw 180 degree arc of equal size on each side.

The compass size should be the same for the whole process, be careful.

Make 90 degrees angle for both side and cross two arcs from each 90 degrees. The point thus obtained should be produced vertically towards the line AB. The point on the line segment is the line bisector.

Answer:

2:6

Step-by-step explanation:

You spin it 6 times, you have a chance of getting two options

^^ this is a guess but it seems pretty reasonable

The best prediction possible for the number of times the spinner will land on yellow if it is spun 6 times is 1.

If the spinner has 12 equal parts and 2 of them are yellow, then the probability of the spinner landing on yellow is 2/12, or 1/6. This means that out of every 6 spins, we can expect the spinner to land on yellow once.

To find the best prediction for the number of times the spinner will land on yellow if it is spun 6 times, we can use the idea of expected value. The expected value of an event is the average value we would expect to see if the event were repeated many times.

Expected value = Probability of yellow x Number of spins

Expected value = (1/6) x 6

Expected value = 1

This means that out of 6 spins, we can expect the spinner to land on yellow approximately 1  times on average.
