For each line, determine whether the slope is positive, negative, zero, or undefined.
Answer:
1. Undefined
2. Negative
3. Zero
4. Positive
Step-by-step explanation:
1. Undefined, the line moves in both directions vertically. It's impossible to tell what the slope is.
2. Negative, the line is decreasing at a constant rate, the slope is negative.
3. Zero, the line doesn't increase or decrease, therefore the slope is 0. (No changes)
4. Positive, the line is increasing at a large rate, the slope is positive.

Find the Least Common Denominator. Then, express each fraction using the Least Common Denominator.
7/10 and 5/6
Answer:
LCM of 7/10- 70
LCM of 5/6- 30
Step-by-step explanation:
Solution:
To find the Least common denominator (LCD) of 7/10 and 5/6, we need to find the Least common multiple of 10 and 6.
I found the LCM through division method. Refer to image attached~
We can tell that:
The LCM is 2 x 3 x 5, which when simplified, we obtain 30. The LCD is 30.Now, let's multiply the denominators and the numerators such that 30 is the denominator in both fractions.
=> 7/10 = 7 x 3/10 x 3 = 21/30=> 5/6 = 5 x 5/6 x 5 = 25/30The fractions are:
21/30 and 25/303,100 x 1/10 what is the value of the expression?
Answer: 310
Step-by-step explanation:
Multiplying a value by 1/10 is the same as dividing by 10.
Therefore, 3100* 1/10 = 3100/10
3100/10 = 310.
Hey there!
3,100 × 1/10
= 3,100/1 × 1/10
= 3,100(1) / 1(10)
= 3,100 / 10
= 3,100 ÷ 10 / 10 ÷ 10
= 310 / 1
= 310 ÷ 1
= 310
Therefore, your answer is: 310
Good luck on your assignment & enjoy your day!

Seth and Ted can paint a room in 6 hours if they work together. If Ted were to work by himself, it would take him 1 hours longer than it would take Seth working by himself. How long would it take Seth to paint the room by himself if Ted calls in sick
Answer:
11.5 hours
Step-by-step explanation:
It would take Seith x hours to paint the room by himself, then Ted needs x + 1 hour.
During 1 hour, Seith can do 1/x of the work, Ted can do 1/(x+1) of the work, then we have
1/x + 1/(x + 1) = 1/6
(2x + 1)/[x(x+1)] = 1/6
x(x+1)=6(2x+1)
x^2 + x = 12x + 6
x^2 - 11x - 6 = 0
[tex]x=\frac{11+\sqrt{145}}{2}= 11.5 hours[/tex]
does anyone know the answer?
Answer:
Part A: 9.75x > 195
Part B: x > 20
Step-by-step explanation:
Let's say Mark works for x hours. For each hour he works, 9.75 dollars are added to Mark's salary. Therefore, for 1 hour, he gets $9.75, for 2 hours, he gets $9.75 + $9.75 = $9.75 * 2 = $19.50, and for x hours, he gets $9.75 * x as his salary.
We want his salary to be more than $195, so we have $9.75 * x (his salary) > $195, which can be written as 9.75x > 195
divide both sides by 9.75 to solve for x
x > 20

height of trapezium if the area given is 124
Short base: 12 cm
Long base: 19 cm
Height:?
Answer:
A= 0.5 x (a+b) x h
124 = 0.5 x (12+19) x h
124 = 15.5 x h
÷15.5
h = 8cm
0.5x(12+19) x 8 does gives 124
Thus, height is 8cm.
Hope this helps!

HELP PLEASE! whats the height and base??
Answer: 7.5
Step-by-step explanation:
Area of the bottom left triangle = 4x3/2 = 6
Bottom right = 6x3/2 = 9
Top right = 3x4/2 = 6
Top left = 6x3/2 = 9
6+9+6+9 = 30
Each square unit is 4
So the answer should be 30/4 = 7.5

X x 15 = 8 1/3. what is X
Answer:
4
Step-by-step explanation:
yes 1x is the same a x Technically the 1 front of the x is called implied so it's simply written as x say x=4
Answer:
5/9
Step-by-step explanation:
I assume the second x is a times.
X*15=8 1/3
Divide both sides by 15
x= 5/9 or .555 repeating forever

The radius of circular pipe is 12cm,what length of tape is required to wrap once around the pipe(use pie =3.14)
Answer:
75.36 cm
Step-by-step explanation:
We need to find the circumference of the pipe.
Circumference of a circle = 2[tex]\pi[/tex]r (where r is the radius)
Given:
r = 12 cm[tex]\pi[/tex] = 3.14⇒ circumference = 2 x 3.14 x 12 = 75.36 cm
Sum of two numbers 80 and difference is 40. Find two
numbers.
Answer:
The two numbers are 20 and 60
Step-by-step explanation:
Two numbers: x and y
x + y = 80
x - y = 40
x = y + 40
Substitute x
y + 40 + y = 80
2y + 40 = 80
2y = 40
y = 20
Substitute y, so x = 60

Write the trinomial as a square of a binomial or as an expression opposite to a square of a binomial: -1 + 4a -4a^2
Answer:
-(1 - 2a)^2
Step-by-step explanation:
-1 + 4a - 4a^2
= -[1^2 - 2*1*(2a) + (2a)^2]
= -(1 - 2a)^2
Answer:
Step-by-step explanation:
Begin by taking out the minus
-(4a^2 - 4a + 1) The answer is the square root of the 1st and 3rd terms.
√4a^2 = 2a
√1 = 1 Since middle term is minus, one of 2a or 1 must also be minus
Usually the one is made minus.
That leaves you with a perfect square
- (2a - 1)^2 There are more ways than 1 to write this, but I think this is the clearest answer
What is the volume of this sphere?
Use a = 3.14 and round your answer to the nearest hundredth.
2 in
Answer:
33.49 cubic inches
Step-by-step explanation:
the volume of a sphere is represented by (4/3)pi(r)^3
pi is 3.14 and r is 2
so 4/3(3.14)(2^3)
2^3 is also 8
4/3(3.14)(8)
the final answer is 33.4933333
OR when rounded it is 33.49
Statement:
The radius of the sphere is 2 inches.
To find out:
The volume of the sphere.
Solution:
Radius (r) = 2 inπ we have to consider as 3.14.We know, volume of a sphere [tex] = \frac{4}{3} \pi \: {r}^{3} [/tex]Therefore, the volume of the sphere[tex] = \frac{4}{3} \times 3.14 \times {(2)}^{3} \: \: cubic \: \: inches \\ = \frac{4}{3} \times 3.14 \times 8 \: \: cubic \: \: inches \\ = 33.49 \: \: cubic \: \: inches[/tex]
Answer:
The volume of the sphere is 33.49 cubic inches.
