What is v

Answer:

20:9

Step-by-step explanation:

Here we will simplify the ratio to 40:18 for you and show you how we did it.

To simplify the ratio 40:18, we find the greatest common divisor of 40 and 18, and then we divide 40 and 18 by the greatest common divisor.

The greatest common divisor that you can use to simplify 40:18 is 2. This means the answer to ratio 40:18 simplified is:

Answer:

Decimal = -1.375, Fraction = -11/8

Step-by-step explanation:

Decimal:

-2.25 + 0.4x = -2.8

0.4x = -0.55

x = -1.375

Fraction:

-9/4 + 2/5x = -14/5

-45/20 + 8/20x = -56/20

8/20x = -11/20

x = -11/8

a. The answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.

b. The answer is: The fewest number of multibase blocks required to represent 10 longs in base three is 3 flats and 1 unit.

a. To represent 20 longs in base seven, we need to find the fewest number of multibase blocks required.

In base seven, we have the following conversions:

1 long = 1 unit

1 flat = 10 units

1 block = 10 flats

To represent 20 longs, we can use 2 flats (each flat representing 10 units) and 0 units since there are no remaining units.

So, the fewest number of multibase blocks required would be 2 flats.

Therefore, the answer is: The fewest number of multibase blocks required to represent 20 longs in base seven is 2 flats.

b. To represent 10 longs in base three, we need to find the fewest number of multibase blocks required.

In base three, we have the following conversions:

1 long = 1 unit

1 flat = 3 units

1 block = 3 flats

To represent 10 longs, we can use 3 flats (each flat representing 3 units) and 1 unit since there is one remaining unit.

So, the fewest number of multibase blocks required would be 3 flats and 1 unit.

Therefore, the answer is: The fewest number of multibase blocks required to represent 10 longs in base three is 3 flats and 1 unit.

2 on division by 3/7 yields 14/3.

For the division of two fractions, we need to multiply the first fraction with the reciprocal of the second. Reciprocal of a fraction means interchanging the numerator and denominator ie, the reciprocal of a is 1/a, the reciprocal of p/q = q/p, and so on.

For example, if a/b and c/d are the fractions the a/b ÷ c/d = a/b x d/c =ad/bc.

Implementing the same method to solve this question,

We have 2/1 = 2 as the first and 3/7 as the second fraction. Thus,

2 ÷3/7 =2 x 7/3 = 14/3. So 14/3 is the answer.

Answer:

The answer is 88 square inches. (A)

Step-by-step explanation:

The shape is broken up into 2 right triangle sand 2 rectangles.

The area of the triangle is 12. You subtract the way it is cut in half where the dashed line that sais (4 in.) so you take 7 - 4 = 3. Now that the 3 is left meaning it is the height  of the triangle. and then the bashed line that says

(8 in.) is the base of the triangle. Multiply that and it is 24 but you have to divide by 2 which gives you 12. since there are "Identical" triangles what I do is add 12 which will give you 24 again bc of both triangles combined.

As for the rectangle is both dashed lines (4 in. And 8 in.) multiply it gives you 32, again since here is another "Identical" rectangle you add 32 + 32 = 64 (Both rectangles combined)

Lastly add 64 + 24 = 88

Answer:

x + x - 45 = 90

2x - 45 = 90

2x = 135

x = 67.5, so x - 45 = 22.5

The other two angles measure 22.5° and 67.5°.

Answer:

To solve the equation:

2/3x - 1/5x = x - 1

First, we need to find a common denominator for 2/3 and 1/5, which is 15. So we can rewrite the equation as:

(10/15)x - (3/15)x = 15/15 x - 1

Simplifying the left side:

(7/15)x = 15/15 x - 1

Multiplying both sides by 15:

7x = 15x - 15

Subtracting 7x from both sides:

-8x = -15

Dividing both sides by -8:

x = 15/8 or 1.875

Therefore, the solution to the equation is x = 1.875.

When we roll a cube numbered from 1 to 6, the chances of rolling each of the six numbers are is equally distributed.

So, the chance of rolling a number greater than or equal to 2 is the sum of the chances of rolling any of the numbers 2, 3, 4, 5, or 6.

On the other hand, the chance of rolling a number less than two is the chance of rolling only 1.

Therefore, comparing those two cases, it is:

more likely to roll a number greater than or equal to 2

The area of the right triangle is 155.25 square feet.

What is triangle?

A triangle is a polygon that has three sides and three angles. It is a closed shape with three straight sides that meet at three vertices. The sum of the angles in a triangle is always 180 degrees. Triangles are one of the basic shapes in geometry and are used in many mathematical and scientific applications.

To find the area of a right triangle with a height of 13.5 feet and a base of 23 feet, we can use the formula:

Area = (1/2) x base x height

Plugging in the given values, we get:

Area = (1/2) x 23 x 13.5

Simplifying the expression, we get:

Area = 155.25 square feet

Therefore, the area of the right triangle is 155.25 square feet.

The statement translated to an algebra equation will give the value of the unknown number w = 11/5

Algebra is the branch of mathematics that helps to represent problems or values in the form of mathematical expressions using letters to represent unknown values.

Let us represent the unknown number with the letter w so that the statement can be written as the equation:

5w - 8 = 3

add 8 to both sides

5w - 8 + 8 = 3 + 8

5w = 11

divide through by 5

5w/5 = 11/5

w = 11/5

Therefore, the statement translated to an algebra equation will give the value of the unknown number w = 11/5

Time to get to Greg's house =

(4.9 mi)/(15 mi/hr) = about .327 hours = about 19.6 minutes (19 minutes, 36 seconds)

Shortcut:

Distance to Greg's house:

\( \sqrt{ {3.2}^{2} + {1.7}^{2} } = 3.6235 \)

Time to get to Greg's house:

(3.6235 mi)/(15 mi/hr) = about .242 hours = about 14.49 minutes (14 minutes, 30 seconds)

The shortcut is about 4.9 - 3.6235 = 1.28 miles faster (about 5.11 minutes, or 5 minutes, 6 seconds faster)

The unknown sides of the right angle triangle using trigonometric ratios are as follows;

PR = 13.2 units

RQ = 17.6 units

A right angle triangle is a triangle that has one of its angles as 90 degrees.

The sides of the triangle can be found using trigonometric ratios.

Therefore,

sin 37° = opposite / hypotenuse

sin 37° = PR / 22

cross multiply

PR = 22 sin 37

PR = 22 × 0.60181502315

PR = 13.2399305093

PR = 13.2 units

cos 37 = adjacent / hypotenuse

cos 37 = RQ / 22

RQ = 22 cos 37

RQ = 17.569981221

RQ = 17.6 units

Since y is not equal to 10, hence the coordinate point does not fall on the line graph.

Since we are not given a graph, we will use the attached graph as a reference:

The equation of a line is expressed as y = mx + b

m is the slope

b is the y-intercept

Get the slope of the line

\(m = \frac{0-(-2)}{-2-0}\\m=\frac{2}{-2}\\m = 1\)

Since the line suts the y-axis at y = -2, hence b = -2

Get the equation of the line:

Recall that y = mx + b

y = x + (-2)

y = x - 2

Next is to check if the coordinate (5, 10) lies on the line
