Last month, took Lucas 32 minutes to run 3 miles. This month is took him 28 minutes. Find the percent of change.

Answer:

x = y + v/b

Step-by-step explanation:

You can solve for x by adding v/b to both sides since that is what will isolate x the quickest and that is what you want to do when you need to solve for something.

By adding v/b to both sides, you will end up with x=y+v/b and that’s your answer!

Hope this helps!

Answer:

1/6

Step-by-step explanation:

6x+8= 9

Subtract 8 from both sides:

6x+8-8= 9-8

6x= 1

Divide by 6 on both sides

6/6x= 1/6

x= 1/6

Answer: x=1/6

Step-by-step explanation:

subtract the 8 from the left side to the right side to get 9-8= 1. then you will have 6x=1. divide six on both sides to get x=1/6

Answer:

1.25cups(8oz/1cup)=10 ounces

Step-by-step explanation:

we convert 1 1/2 quarts to cups. There are 4 cups in a quart:

1 1/2 quarts= 3/2 quarts (4 cups/ 1 quart)= 6 cups

Amount poured out:

6 cups- 3.5 cups= 2.5 cups

Amount poured in each cup:

2.5/2=1.25 cups

The value of x is 15.

Here first we add P and Q together that equals x+13

After this, it  divide x+13 and 8 and make it equal to [tex]21\div x-9[/tex]

Now x should then equal 15

[tex]x+13\div 9 = 21\div x-9\\x^2+4x−117=168\\\\x^2 + 4x-285=0[/tex]

(x−15)(x+19)=0

x = 15

Therefore we can conclude that The value of x is 15.

To find the value of x in a similar triangle question, you need to identify the corresponding sides and use their ratio to solve for x. In this case, PQR is similar to SQT, and the corresponding sides are PQ and SQ, PR and ST, and QR and QT. The ratio of the side lengths can be used to find the value of x.

If two triangles are similar, it means that their corresponding angles are equal, and the ratio of their corresponding side lengths is constant. In the given question, PQR is similar to SQT. To find the value of x, we need to identify the corresponding sides and find the ratio between them. Let's assume that the corresponding sides are PQ and SQ, PR and ST, and QR and QT. The ratio of the side lengths can be written as:

x / (p + q) = PQ / SQ. Using this ratio, we can solve for x by multiplying both sides of the equation by (p + q):

x = (PQ / SQ) * (p + q)

To express 123,000,000 as a multiple of a power of 10, we identify it as 1.23 x 10^7.

The question asks to express 123,000,000 as a multiple of a power of 10. To do this, we need to understand how exponents of 10 work. The exponent tells us how many zeros are added to the right of 1 to create the number. For instance, 10^2 equals 100 because there are two zeros.

In the case of 123,000,000, we count the zeros following the initial digit(s). There are 7 zeros. Therefore, we can express 123,000,000 as 1.23 x 10^7. Here, 1.23 is the coefficient (a value greater than or equal to 1 but less than 10), and 10^7 indicates that the decimal point in 1.23 is moved 7 places to the right to get the original number, 123,000,000.

This method of notation is commonly used in scientific notation, which simplifies large numbers by expressing them as a multiple of a power of 10. It's a useful way to work with very large or very small numbers efficiently.

Answer:0.32

Explanation:

The reason why this is the answer is because  if you look at a place value chart, you could see that hundreds is the second place after the decimal point so you would put the numerator right after the decimal point.

A decimal that is equivalent to the fraction 32/100 is 0.32.

We can convert a fraction to a decimal by dividing the numerator by the denominator. For example, to convert 32/100 to a decimal, we divide 32 by 100, which gives us 0.32.

To convert a fraction to a decimal, we divide the numerator (top number) by the denominator (bottom number).

In this case, we want to convert 32/100 to a decimal. Dividing 32 by 100 gives us 0.32 as the decimal equivalent of the fraction.

A fundamental mathematical concept is the ability to transform a fraction to a decimal. In a fraction, the denominator denotes the total number of parts in the whole, whereas the numerator denotes the number of pieces. Divide the numerator by the denominator to convert a fraction to a decimal. To obtain the decimal equivalent of 32 in this situation, we divide 32 by 100. By multiplying this decimal by 100, we can also convert it to a percentage, which gives us 32%.

Therefore, the decimal equivalent of 32/100 is 0.32.

Final answer:

To find the volume of a cuboid, multiply its length, width, and height. If made of 1 cm cubes, the volume is the number of these cubes. Halving the cuboid evenly would halve its volume.

Explanation:

To calculate the volume of a cuboid, you multiply the length, width, and height of the cuboid. The question doesn't provide specific dimensions, but assuming that you have them, the formula you would use is Volume (V) = length × width × height. If the cuboid consists of centimeter cubes, each with a side length of 1 cm, the volume in cubic centimeters will be equal to the number of these small cubes.

For example, let's say the dimensions of the cuboid are 5 cm × 3 cm × 4 cm. The volume would then be calculated as V = 5 cm × 3 cm × 4 cm = 60 cm³.

If the cuboid is split in half, the resulting two pieces would each have a volume that is half of the original total volume, assuming the split is made evenly.

Answer:

14.17m

Step-by-step explanation:

1 / 1.2 = x / 17

x = 17 / 1.2 = 14.1666667 -> 14.17m

14.17m tall is the building (to 2 decimal places).

Digits after the decimal point. The position of the digit to the right of the decimal point of the number is written in decimal notation. For example, 0.079 has 0 decimal places, 7 decimal places, and 9 decimal places.

Rounding a decimal number to two decimal places is the same as rounding to one-hundredth of the second decimal place. For example, 2.83620364 can be rounded from 2.84 to two decimal places, and 0.7035 can be rounded from 0.70 to two decimal places.

1 / 1.2 = x / 17

Step-by-step explanation:

The required y coordinate of E is -8. Option A is correct.

The graph is shown, point E Is drawn on the graph so that line EF is parallel to line CD. Point E is (-4, y), and the value of y is to be determined.

The line is a curve showing the shortest distance between 2 objects in space.

Here, the Slope of line CD = 2/5 = slope of line EF (cause both lines are parallel)

The Coordinate of point f is (6,-4)
Line EF y+4 =2/5(x-6)
The coordinate of E is (-4, y)
for x = -4
y+4=2/5(-4-6)
y+4 = 2/5(-10)
y = -2*2-4
y = -8
than coordinates of E is (-4,-8)

Thus, the required y coordinate of E is -8

All the described pairs of triangles that are reflected, rotated, or both, can be proven congruent by the SAS postulate because such rigid transformations preserve the congruency of sides and angles.

To determine which pair of triangles can be proven congruent by the SAS (Side-Angle-Side) postulate, we look for two sides of a triangle and the included angle that are congruent to two sides and the included angle of another triangle. When a triangle is reflected across a line, rotated 90 degrees, or both reflected and rotated, it maintains its size and shape, thus the corresponding sides and angles remain congruent.

A reflection or rotation (including a combination of both) is a type of rigid transformation which preserves the size and shape of figures. Hence, all the given pairs of triangles can be proven congruent to the original triangle through the SAS postulate, as rigid transformations do not alter the congruity of sides and included angles.
