Answer:

20 - 17

Step-by-step explanation:

Decreased means subtract

20 - 17

The correct translation of the expression "20 decreased by 17" is "20 - 17."

Given is a verbal expression we need to convert it into algebraic form,

To reach this conclusion, we need to understand the phrase "decreased by" means subtraction.

When we say "20 decreased by 17," it implies that we are subtracting 17 from 20. In mathematical terms, this can be represented as 20 - 17.

Let's analyze the other options:

17 - 20: This option represents 17 subtracted by 20, which is the opposite of the original expression and doesn't match the given phrase.

20 + 17: This option represents the addition of 20 and 17, which doesn't align with the original expression. We are looking for subtraction, not addition.

17 + 20: This option also represents addition, and as mentioned before, the original expression involves subtraction, not addition.

Therefore, the correct answer is 20 - 17.

Answer:

To convert from a decimal to percent, multiply a decimal by 100 and add the percent sign.

Example: 0.10 becomes 0.10 x 100 = 10%

Example: 0.22 becomes 0.22 x 100 = 22%

To convert from a percent to a decimal, divide a percent by 100 and remove the percent sign.

Example: 10% becomes 10/100 = 0.10

Example: 22% becomes 22/100 = 0.22

Answer:

C. 23%

Step-by-step explanation:

C. The probability that the student takes Spanish or French is 23%

If two events can not occur together at same time, then the events are called mutually exclusive.

If two events are mutually exclusive, then,

P(A∪B) = P(A)+P(B)

And If two events are not mutually exclusive, then,

P(A∪B) = P(A)+P(B)-P(A∩B)

In central high school,

15% of the students take Spanish language = P(A) (say)

12% of the students take French language = P(B) (say)

& 4% of the students take both the languages = P(A∩B)

Since some of students take both languages, so this is not mutually exclusive.

The probability that the student takes Spanish or French is P(A∪B).

∴ P(A∪B) = P(A)+P(B)-P(A∩B)

               = 15%+12%-4%

               = [tex]\frac{15}{100}+\frac{12}{100}-\frac{4}{100}[/tex]

               = [tex]\frac{15+12-4}{100}[/tex]

               = [tex]\frac{23}{100}[/tex] = 23%

Hence, Required probability is 23%

Answer:

x = - 6/7

Step-by-step explanation:

To start, 1x is just 1 times x, which you can just write as x.

x+3 = 8x+9

Then, you can bring x over to the other side of the equation, meaning it becomes -x. You can also think about subtracting x from both sides so it cancels out on the left.

3 = 8x+9-x

Next, do the same for the 9, so your equation looks like this:

3-9 = 8x-x

Just simplify it:

-6 = 7x

Finally, divide -6 by 7 to find x.

So, x = -6/7

Answer:

y= (2/3)x - 4

Step-by-step explanation:

To answer this you'll want to use the slope intercept form of a line:

y= mx + b

So to solve essentially you just have to find the values for m and b

- m represents the slope of the line

- b is the y-intercept (the point where the line crosses the y-axis)

You can figure that b = -4 because the line will cross the y-axis when x = 0, and you are given the point on the line (0,-4), where x is equal to 0.

Now to find the slope of the line, since you are given two points on the line you will want to use the slope equation:

slope = [tex]\frac{y1-y2}{x1-x2}[/tex]

So you can assign each of the two points a number (1 or 2) where its values are equal to (x1, y1) or (x2, y2). It does not matter which point gets which number.

In this example:

We will assign the point (6,0) to be (x1, y1),

and we will assign the point (0, -4) to be (x2, y2)

So we end up with the following:

m= [tex]\frac{0- (-4)}{6-0}[/tex]

m=  [tex]\frac{0+4}{6}[/tex]

m=  [tex]\frac{4}{6}[/tex]

Simplify the fraction:

m = [tex]\frac{2}{3}[/tex]

From there you just substitute in for m and b into the slope intercept equation

Answer:

7.1 m

Step-by-step explanation:

A cube has 6 congruent square faces.

Given the surface area = 302.46 m² then the area of one face is

302.46 ÷ 6 = 50.41 m²

The area of a square = s² ( s is the side length ), thus

s² = 50.41 ( take the square root of both sides )

s = [tex]\sqrt{50.41}[/tex] = 7.1 m

The length of each side of the cube is 7.1 m

So the right options are:

Answer:

a = - 7

Step-by-step explanation:

Given

5 + 2a = - 9 ( subtract 5 from both sides )

2a = - 14 ( divide both sides by 2 )

a = - 7

Answer:

a = -7

Step-by-step explanation:

5 + 2a = -9 {Subtract 5 form both sides}

5 + 2a - 5 = -9 - 5

2a = -14

Divide both sides by 2

2a/2 = -14/2

a = -7

Answer:

f(8) = f(1)+35

Step-by-step explanation:

f(8) = f(7) + 5

We are adding 5 each time

f(7) = f(6)+5

f(6) = f(5) +5

f(5) = f(4)+5

f(4) = f(3) +5

f(3)=f(2)+5

f(2)=f(1)+5

f(8) = f(7) + 5

Replacing

f(8) = f(6)+5 + 5

f(8) = f(5)+5+5 + 5

f(8) = f(4)+5+5+5 + 5

f(8) = f(3)+5+5+5 + 5+5

f(8) = f(2)+5+5+5+5 + 5+

f(8) = f(1)+5+5+5+5+5 + 5+5

f(8) = f(1)+35

Answer:

f(8) = f(1)+35

Answer:

m = - 1. (Slope)

Step-by-step explanation:

To find the slope of a line, you will need to use the slope formula: [tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

Plug in the 'x' and 'y' value of each coordinate into the equation:

[tex]m = \frac{0-6}{2-(-4)}[/tex]

Simplify this:

[tex]m = \frac{-6}{6}[/tex]

m = -1.

Therefore, the slope of the line is m = -1.

Answer:

c = 50

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

c² = 48² + 14² = 2304 + 196 = 2500 ( square root both sides )

c = [tex]\sqrt{2500}[/tex] = 50

Answer:

4sqrt(3) inches

Step-by-step explanation:

The ratio of the lengths of the legs of a 30-60-90 triangle is:

short leg : long leg : hypotenuse

1 : sqrt(3) : 2

The long leg is sqrt(3) times the length of the short leg.

Here, the short leg measures 4 inches.

long leg = sqrt(3) * short leg

long leg = 4sqrt(3) inches

Question:

Find the area of the shaded segment. Round your answer to the nearest square centimeter.

a) 24 cm²

b) 23 cm²

c) 21 cm²

d) 22 cm²

Answer:

d) 22 cm²

Step-by-step explanation:

We have Area and a Triangle in that diagram.

In other to find the shades segment , we have to find the Area of the triangle and the Area of the sector

Step 1

Area of a Triangle

= 1/2 × a × b × sin θ

Where θ = 120°

a = 6 cm

b = 6 cm

Area of the triangle = 1/2 × 6 × 6 × sin 120°

= 15.59 cm²

Step 2

Area of the sector

The formula is given as

Area = πr²θ/360

r = radius = 6cm

Area = π × 6² × 120/ 360

Area = 37.699111843cm²

Approximately = 37.70 cm²

Step 3

The Area of the shaded segment = Area of the sector - Area of the triangle

= 37.70cm² - 15.59cm²

= 22.11 cm²

Approximately to the nearest square centimeter

= 22 cm²

7u+8v=2v

Subtract 8v from both sides:

7u=-6v

Divide both sides by -6:

v=-7/6u

Step-by-step explanation:

Let's assume that Patrick is travelling on a straight line throughout the whole path in order to minimize the distance.

The number of miles that he can travel on a full tank is:

[tex]m = 5\ mpg*4\ gallons\\m=20\ miles[/tex]

The distance travelled by Patrick in one hour (from 2p.m. to 3p.m.) is:

[tex]d^2=6^2+8^2\\d=\sqrt{100}\\ d=10\ miles[/tex]

If he is travelling at 10 miles per hour, and he could travel for a total of 20 miles, then the time remaining before the tank runs out of gasoline is:

[tex]t=\frac{20-10}{10}\\ t=1\ h[/tex]

If he continues at this rate, the gas will last for 1 more hour.

Answer:

Step-by-step explanation:

y and 76 are vertically opposite angles

x and z are vertically opposite angles

Linear pairs.

If sum of two adjacent angles are 180, then they are linear pair.

x & 76 are linear pairs

y & z are linear pairs

z & 76 are linear pairs

x and y are linear pairs

Solutions:

y = 76   { vertically opposite angles are equal}

x + 76 = 180  { linear pair}

x = 180 - 76

x = 104

z = x  {Vertically opposite angles are equal}

z = 104
