which sets of side lengths could form a triangle?

Answers

To solve this question we will have to make use of the triangle inequality which states that "the sum of the lengths of any two sides of a triangle must be greater than the length of the third side".

Let us now use this inequality to check Part A to Part E.

Part A: [tex] 3+4\ngtr9 [/tex] therefore, triangle is not possible

Part B: [tex] 3+6\ngtr9 [/tex] therefore, triangle is not possible

Part C: [tex] 4+5\ngtr9 [/tex] therefore, triangle is not possible

Part D: [tex] 4+6>9, 4+9>6, 6+9>4 [/tex] As all the three sides adhere to the triangle inequality, a triangle is possible with these dimensions.

Part E: [tex] 5+5>9, 5+9>5, 9+5>5 [/tex] As all the three sides adhere to the triangle inequality, a triangle is possible with these dimensions.

Thus, only Options D and E apply

What is the area of this parallelogram?

28 m²

56 m²

84 m²

120 m²

Answers

The area will be 84m^2
because 12x7=84

the area of the parallelogram is divided into 3 areas: two of them for two triangles with the same area and one rectangle.
the area of the rectangle = Length*Width =8*7 =56 sq.m
the area of one of the triangles = 0.5*base*height= 0.5*4*7=14 sq.m
the total area of the parallelogram= 2*area of a triangle+area of the rectanlge
= 2*14+56 =28+56= 84 sq.m (plz double check the answer with your calculator and follow the same procedure)

line XY is perpendicular to line CD at D. Which conclusion can be drawn?

Answers

I have attached the choices given for this question

Answer:
measure angle XDC = 90 degrees

Explanation:
The term "perpendicular" implies that the angle formed between the two lines is 90 degrees.
These two lines do not have to be equal in length, they just intersect forming a 90-degree angle.

Comparing the explanation with the given choices, we would find that the only correct choice is:
measure angle XDC = 90 degrees

The sum of four consecutive integers is -22

Answers

Consecutive integers are numbers that follow each other op in order.
The four integers you're looking for are
-4
-5
-6
-7

This is because they add up to -4 + -5 + -6 + -7 = - 4 - 5 - 6 - 7 = - 22

x= 1st integer
x+1= 2nd integer
x+2= 3rd integer
x+3= 4th integer

Add the above integers and set equal to -22.

x + (x+1) + (x+2) + (x+3)= -22
combine like terms
4x + 6= -22
subtract 6 from both sides
4x= -28
divide both sides by 4
x= -7

ANSWER:
x= -7
x+1= -6
x+2= -5
x+3= -4

Simplify a - {b - [c- (d - e) - f] - g]

Answers

Answer is a - b + c - d + e - f + g

Answer:

After Simplifying we get a - b + c - d + e - f + g

Step-by-step explanation:

We are given : a - { b - [ c - ( d - e ) - f ] - g }

We have to simplify it.

Step 1: First open the parenthesis mean ( ) brackets

we get , a - { b - [ c - d + e - f ] - g }

Step 2: Now we open Square brackets .i.e., [ ]

we get, a - { b - c + d - e + f - g }

Step 3: In last we open curly brackets .i.e, { }

we get, a - b + c - d + e - f + g

Therefore, After Simplifying we get a - b + c - d + e - f + g

A dot ran from -34 to -66. What distance did it cover? If this run took the dot 5 minutes, what was the average speed?

Answers

-100. At a average speed of 20.

The dot's average speed was 384 units per hour

To find the distance the dot covered, we can subtract the initial position from the final position:

Distance = Final position - Initial position

[tex]\[ \text{Distance} = (-66) - (-34) \]\[ \text{Distance} = -66 + 34 \]\[ \text{Distance} = -32 \][/tex]

However, distance is a scalar quantity, so the negative sign indicates the direction. To find the magnitude of the distance, we take the absolute value:

[tex]\[ |\text{Distance}| = |-32| \][/tex]

[tex]\[ |\text{Distance}| = 32 \text{ units} \][/tex]

So, the dot covered a distance of 32 units.

To find the average speed, we use the formula:

[tex]\[ \text{Average speed} = \frac{\text{Distance}}{\text{Time}} \][/tex]

Given that the run took the dot 5 minutes, we need to convert the time to hours for the speed to be in units of distance per hour:

[tex]\[ \text{Time} = 5 \text{ minutes} = \frac{5}{60} \text{ hours} = \frac{1}{12} \text{ hours} \][/tex]

Now, plug the distance and time into the formula:

[tex]\[ \text{Average speed} = \frac{32 \text{ units}}{\frac{1}{12} \text{ hours}} \]\[ \text{Average speed} = 32 \times 12 \]\[ \text{Average speed} = 384 \text{ units/hour} \][/tex]

So, the dot's average speed was 384 units per hour.

Your second pool has a volume of (10 ft)*(8 ft)*(5 ft) = 400 ft^3, which is 8 times 50 ft^3. It can be expected to take 8 times as long to fill, so 8 hours.

Answer:

8 hours

Step-by-step explanation:

10 x 8 x 5 = 400. 400 / 50 = 8. So it will take 8 hours to fill a pool with 400ft3

What number is a common denominator for 3/8and1/3

Answers

Hello!

24 is the LCD for 3/8 and 1/3.

The least common multiple is 24, so the LCD is 24, too. A "Common Denominator" is a number that can be divided by all the denominators in a group of fractions.

A common denominator is when the denominators (or the value in the bottom of the fraction) is made the same through multiplication, etc.

24 is a common denominator for this example:

3/8(3/3) = 9/24
1/3(8/8) = 8/24

9/24 and 8/24 have common denominators, while their numerators are also multiplied, for 'what you do to the bottom, you do to the top' (sorry forgot the exact term for it)

The correct answer is the last option: 5,12,13

Explanation:

1. The hypotenuse of the triangle is the larger side. Keeping this on mind, you must apply the Phytagorean Theoream, as below:ç

a²=b²+c²

"a" is the hyptenuse and "b" and "c" are the legs of the right triangle.

2. Then, you have:

a=13
b=12
c=5

3. If you apply the formula above to calculate the hypotenuse and the result is 13, then those are the lengths of sides of the right triangle. Therefore:

a²=b²+c²
a=√b²+c²
a=√(12)²+(5)²
a=√144+25
a=13

Rewrite the following equation in slope-intercept form. 5x − 14y = 16 Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Final answer:

The equation 5x − 14y = 16, when rewritten in slope-intercept form, is[tex]y = (5/14)x - 8/7.[/tex]

Explanation:

To rewrite the given equation in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept, we'll isolate y. Starting with the equation 5x − 14y = 16:

1. Subtract 5x from both sides to move the x term to the other side:

-14y = -5x + 16

2. Divide every term by -14 to solve for y:

y = (5/14)x - 8/7

In this form, the coefficient of x represents the slope (m), which is 5/14, and the constant term is the y-intercept (b), which is -8/7. The slope indicates the rate of change of y concerning x, and the y-intercept represents the point where the line intersects the y-axis.

By following these steps, we've successfully transformed the given equation into slope-intercept form, making it easier to interpret and work within the context of linear relationships.

Final answer:

To convert the equation 5x - 14y = 16 to slope-intercept form, solve for y to yield y = (5/14)x - 8/7, where the slope is 5/14 and the y-intercept is -8/7.

Explanation:

To rewrite the equation 5x − 14y = 16 in slope-intercept form, we need to solve for y to get the equation in the form of y = mx + b, where m is the slope and b is the y-intercept.

First, we subtract 5x from both sides of the equation:5x − 14y − 5x = 16 − 5xThis simplifies to −14y = −5x + 16.Next, we divide each term by −14 to solve for y:y = (−5x + 16) / −14Finally, we simplify the equation:y = (5/14)x − 16/14

In simplified form, the slope-intercept form of the equation is y = (5/14)x − 8/7. Here, the slope (m) is 5/14 and the y-intercept (b) is −8/7.

Ms.Gartland bought x number of shirts for the new members of her chorus.The cost for x number of shirts,including $3.99 shipping,was $ 77.49.Each shirt cost $12.25.There was no sales tax on this purchase.Which equation could be used to find x?
A 3.99(x+12.25)=77.49
B 3.99x+12.25=77.49
C 12.25(x+3.99)=77.49
D12.25x+3.99=77.49

Answers

D. Is the answer because each shirt costs 12.25. X represents the number. And you subtract it from 3.99 because thats the shipping price.

She bought 'x' number of shirts.

The price of one shirt = 12.25 dollars.

Then total price of all shirts would be '12.25x' dollars.

Given is the shipping charge = 3.99 dollars.

Given is the total bill = 77.49 dollars.

It says no other tax would be charged on this order, so total bill would be sum of total price of all shirts and shipping charges.

Total Bill = Total price of all shirts + Shipping charges.

77.49 = 12.25x + 3.99

Hence, option D is correct i.e. 12.25x + 3.99 = 77.49
