Question:

Gabriel started to calculate the area of the triangle. His work is shown.

A = 1/2 bh=1/2 (1/2) (3/4)

A triangle has a base of three-fourths inch and a height of one-half inch

What is the area of the triangle?

The area of the triangle is ___in.²

Answer:

Area of the triangle = [tex] \frac{3}{16} inch^2 [/tex]

Step-by-step explanation:

We are given the dimensions of the triangle as:

Base, b = ¾ inch

Height, h= ½ inch

To find the area of the triangle, let's use the formula :

Area of a triangle = ½base *height

Solving further, we have:

Area of a triangle = [tex] \frac{1}{2}*\frac{3}{4} * \frac{1}{2} = \frac{3}{16} [/tex]

Area of the triangle = [tex] \frac{3}{16} inch^2 [/tex]

Hey there! I'd be delighted to help you out!

First, let's write down our expression!

[tex](x^2-x)+(8x-2x^2)[/tex]

When we look at this expression, we see that all of the numbers are terms, or numbers that are added. We have four terms in this equation, which are:

[tex]x^2, -x, 8x, -2x^2[/tex]

Now, to simplify, we want to combine like terms. Like terms are numbers that have the same variable (or no variable) and are raised to the same power. 1 and 5 are like terms because they both have no variable and they are both raised to the power of 1 (any number that is itself is raised to this power). 4x and 12x are like terms because they both have an x and a power of 1. 4y and 5x are not like terms because they have different variables. 4x³ and 2x² are not like terms because they are raised to different powers.

Now, we see that  with our numbers, x² and -2x² are like terms, and -x and 8x are also like terms. We can combine accordingly.

[tex]x^2-2x^2=-x^2\\\\-x+8x=7x[/tex]

Now we combine to get our simplified expression!

[tex]-x^2+7x[/tex]

I hope that this helps! Have a wonderful day!

Step-by-step explanation:

Because you do the distance equation

Answer:

4

Step-by-step explanation:

A rectangle has a shorter side and a longer side.

The longer side is called the length and the shorter side is called width.

with the 24 tiles you can make the following rectangles (consider the first number the length and the second number the width, and that each unit represents a tile):

24 x 1

12 x 2

8 x 3

6 x 4

A total of 4 different rectangles.

I am not counting the rectangles than have the same sides shifted, for example 2 x 12 because it is the same as 12 x 2 and we are asked for the rectangles to be different.

I attache an image of the sketch of each rectangle with the labels of length and width (not to scale).

Answer:

[tex]9 \dfrac12 m^2[/tex]

Step-by-step explanation:

Tanya has a garden with a trench around it.

Tanya's garden is a rectangle with length [tex]\dfrac12 \text{m}[/tex] and width 2m.

The trench and garden together make a rectangle with length [tex]3 \dfrac12 \text{m}[/tex] and width 3m.

We are to determine the area of just the trench.

Area of just the trench = Area of the trench and garden together-Area of the garden

[tex]=(3 \dfrac12 X 3)-(\dfrac12 X 2)\\\\=( \dfrac72 X 3)-1\\\\=\dfrac{21}{2}-1\\\\=9 \dfrac12 m^2[/tex]

The area of the trench is [tex]9 \dfrac12 m^2[/tex]

Answer:

B, C.

Step-by-step explanation:

B, because you're multiplying them all, which is what you would do in the normal formula. You would get 255/16, or 15.9375.

C, since you would also get 255/16.

Answer:

A and B

Step-by-step explanation:

The lines are both in slope intercept form:

y=Mx+b

Where m is the slope and b is the y intercept.

We have 2 lines:

y=1/3x+3

y=1/3x-2

1/3 is the coefficient of x, which means the slope is 1/3. Both of these lines have the same slope of 1/3. Since they both have the same slope, they are also parallel lines.

Therefore, A: the same slopes and B: parallel lines is correct.

In the photo, the red line is 1/3x+3 and the blue like is 1/3x-2

Answer:

About 3.7 times or 4 times.

Step-by-step explanation:

6.14 x 10 - 3 = 61.4-3

61.4 - 3 = 58.4

1.98 x 10 - 4 = 19.8 - 4

19.8 - 4 = 15.8

58.4 ÷ 15.8 = 3.696202531645569620253164556962‬ ≈ 3.7 times

Answer:

25% is .25

75% is .75

20% is .2

100% is 1

37.5% is .375

62.5% is .625

87.5% is .875

12.5% is .125

Step-by-step explanation:

Remember DeeP

D.     __.     ____           P

Decimal.                    Percent

You move over two decimal places to the left if you want to convert 35%, which is .35.

You move over two decimal places to the right if you want to convert .45 which is 45%.

Answer:

(x,y) = (-6,-5)

Step-by-step explanation:

If you need the explanation let me know.

Answer:

x = -6

y = -5

Step-by-step explanation:

5x - 4y = -10

5x - 5y = -5

__________--

y = -5

5x - 4y = -10

5x - 4(-5) = -10

5x + 20 = -10

5x = -10 - 20

5x = -30

x = -30/5

x = -6

Answer:

9.958

Step-by-step explanation:

The thousandths spot is where the 8 is so you round 8 with the number behind it 1. Since 1 is below 5, you keep 8 the same and get rid of the 1.

Answer:

9.958

Step-by-step explanation:

find the number in the thousands place, 8 and then look 1 place to the right for the rounding digit 1. Round up if this number is greater than or equal to 5 and round down if it is less then 5.

Answer:

10 > v (if you don't trust me, check it yourself. Subsitute v for 10 in the first equation.

Step-by-step explanation:

1) 7 > v - 3

2) add 3 to both sides

3) so 7 plus 3 equals 10

So you basically do this

7 > v - 3 (ad 3 to both sides)

You get 10 > v (which is as simplified as possible)

Hope this helps! :)

Answer: C

Step-by-step explanation: I chose this answer because in 8th graders, their mean is 6 and their range is 9, that’s a difference of 3. But in 4th graders, their mean is 5 and their range is 6, so there isn’t much of a difference for 4th graders. The answer couldn’t be A, B, or D so I came to the conclusion that it’s C. (Sorry if this explanation doesn’t make sense but I hope I got the right answer.)

The true statement is  the word length varies more in the 8th grade book than the 4th grade book.

Mean is a measure of central tendency. It is the average of a set of values. For example, if the numbers in a data set are 3,2,10, the mean is (3 + 2 + 10) /3 = 5

Range is the highest number less the least number in a data set. For example, if the numbers in a data set are 3,2,10, the range is 10 - 2 = 7

The mean word length for the fourth grade book is 5. While, the mean word length for the eighth grade book is 6. This means that on average, the average word length of the eighth grade book is greater than the mean word length for the fourth grade book

The range word length for the fourth grade book is 6. While, the range word length for the eighth grade book is 9. These means that either the longest word in the eighth grade book is more than that of the fourth grade book or that the smallest word in the eighth grade book is less than than that in the fourth grade book. This means that the  word length varies more in the 8th grade book than the 4th grade book.

Answer:

(C)x=11.6, y=23.2

Step-by-step explanation:

Using Theorem of Intersecting Secant and Tangent

[tex]TQ$ X TP=TR^2[/tex]

[tex]10(10+x+4)=16^2\\10(14+x)=256\\140+10x=256\\10x=256-140\\10x=116\\$Divide both sides by 10\\x=11.6[/tex]

Next, we apply Theorem of Intersecting Chords

PV X VQ=SV X VR

4 X x= 2 X y

Recall: x=11.6

2y=4 X 11.6

2y=46.4

y=46.4/2=23.2

Therefore: x=11.6, y=23.2

The correct option is C
