What is the least common denominator for 1/6 and 3/8
Answers
Answer:
24
Step-by-step explanation:
bc if you were to find what the fractions were before they were simplified, it would be 4/24 (for 1/6) and 9/24 (for 3/8)
The least common denominator for 1/6 and 3/8 is 24.
What is the least common denominator?When two or more fractions are supplied, the least common denominator is the smallest number among all the common multiples of the denominators.
Given, two fraction numbers 1/6 and 3/8
We need to find the least common denominator of them. for that,
We will take the LCM of the denominator of both factors.
LCM of 6 and 8 = 24
Therefore, for fractions 1/6 and 3/8, 24 is the least common denominator.

the area is ___ square units
Answers
Answer:
392 square units
Step-by-step explanation:
We can make 2 right trapezoids out of this shape.
The area of a trapezoid would be 1/2×(b1+b2)×h or (b1+b2)×h ÷ 2.
If we do 1 half it would be 1/2×(14+14)×14 = 196
Now if we multiply by 2 (because we have 2 trapezoids) it would be 392.

Answers
Answer:
I'll do the dilation for the first point and you will see the answer (please verify the second point)
Step-by-step explanation:
The dilation about the origin is straightforward, you just multiply the coordinates of each point by the scale factor.
so the dilated point for (-4,-4) is -4x3.5= -14 which is the same for the y coordinate.
so the dilated point for (-4,-4) is (-14, -14)
Please verify by computing the dilated point for (-6,4)

Answer:
[tex]m(BC) = 72^\circ[/tex]
[tex]m\angle EBC = 168^\circ[/tex]
Step-by-step explanation:
Given
[tex]m\angle BAC = 72[/tex]
[tex]m(BE) = 96[/tex]
See attachment for circle
Required
Determine
(a) Measure of BC
(b) Measure of EBC
(a) Measure of BC
From the attachment, we can see that:
[tex]m(BC) = m\angle BAC[/tex] because they belong to the same sector
This gives:
[tex]m(BC) = 72^\circ[/tex]
(b) Measure of EBC
From the attachment, we can see that:
[tex]m\angle EBC = m(EB) +m(BC)[/tex]
Where
[tex]m(EB) = m(BE) =96^\circ[/tex]
So, we have:
[tex]m\angle EBC = 96^\circ + 72^\circ[/tex]
[tex]m\angle EBC = 168^\circ[/tex]

Teru burned about 1,000 calories downhill skiing before lunch. If she plans to ski
for a total of 5 hours today, how many hours will she ski after lunch?
Answers
Answer:
3.3333 hours
Step-by-step explanation:
From the attached table :
Downhill skiing for 1/6 hours ; results in 100 calories burn
To burn 1000 calories :
Skiing hours required :
(1000 / 100) * (1/6)
10 * 1/6 = 10 /6 hours
Planned skiing hours = 5
Number of skiing hours after lunch will be :
5 hours - 10/6 hours
5 hours - 1.6666 hours
= 3.3333 hours
26. Find the Rate when given the Interest.
Interest: $480
Principal: $1600
Time: 6 years *
(1 Point)
5%
0.05%
20%
2.0%
Answers
Explanation: Use the formula I=prt
Since we do not have the rate, but we have the interest, we plug in everything and try to solve for r (the rate).
480=(1600)(r)(6). To get r alone, we divide out the 6 and 1600. This leaves us with our answer to be r = 0.05. Although this is not in a percentage and we would need it to be, so we would have to multiply it by 100. This gives our percentage to be 5%.

Pedro measured a swimming pool and made a scale drawing. The pool, which is 42 meters long in real life, is 119 centimeters long in the drawing. What scale did Pedro use for the drawing?
Answers
Answer:
The scale that Pedro used for the drawing is: 17:600.
Step-by-step explanation:
A scale of a drawing is expressed as: Drawing length:actual length.
Since you know that the pool is 119 centimeters long in the drawing and 42 meters long in real life, first you have to find the cm in 42 meter taking into account that 1 meter is equal to 100 cm:
1 m → 100 cm
42 m → x
x=(42*100)/1
x=4200 cm
Now, the scale would be:
119:4200
Finally, you need to simplify and you can do it by dividing each number by 7:
17:600
According to this, the answer is that the scale that Pedro used for the drawing is: 17:600.

Write the expression in Distributive Property form (as a Distributive Property problem). 39d - 13e + 195g
Answers
Answer:
13(3d - e + 15g).
Step-by-step explanation:
Distributive property example,
a(x + y + z) = ax + ay + az
By this property we have to convert the given expression into a distributive property form.
39d - 13e + 195g
Take the common factor out from each term of the expression,
39d - 13e + 195g = 13(3d - e + 15g)
Therefore, distributive property form of the given expression is 13(3d - e + 15g).

m[tex]\widehat{WXY}[/tex] is 224°
Step-by-step explanation:
From the figure, we have;
The angle subtended at the circumference, by the arc mWXY, C = 112°
The angle subtended at the center = m[tex]\widehat{WXY}[/tex]
By circle theory, we have;
The angle subtended at the center = 2 × The angle subtended at the circumference
∴ m[tex]\widehat{WXY}[/tex] = 2 × 112° = 224°
m[tex]\widehat{WXY}[/tex] = 224°.

7w - 5 < 1 - 3w
can someone help me ?
Answers
Answer:
w < 0.6
Step-by-step explanation:
In this problem, one is given an algebraic inequality. These types of inequalities can be solved using similar methods that one uses to solve an algebraic expression, in essence, one uses inverse operations. The only major difference between solving algebraic inequalities and algebraic expressions is that when one divides or multiplies by a negative number, one must remember to flip in the inequality sign to maintain the trueness of the equation. In this case, such a rule will not come into play.
7w - 5 < 1 - 3w
Inverse operations,
7w - 5 < 1 - 3w
+3w +3w
10w - 5 < 1
+5 +5
10w < 6
/10 /10
w < 0.6
Answer:
0.6
Step-by-step explanation:
7w - 5 < 1 - 3w
get "w" all on one
7w + 3w - 5 < 1
7w + 3w < 1 + 5
10w < 6
w < 6/10

The compact disc format has been declining in popularity, and one music executive has predicted that CD sales will decrease by 20% per year. If the executive's company sold 29,000,000 CDs this year, how many will the company sell 9 years from now?
Answers
Answer: 3,892,314 CDs
Step-by-step explanation:
You can find this using the future value formula:
Future value = Amount * ( 1 + rate) ^ number of years
Amount = 29,000,000
Rate = -20% because it is decreasing
Number of years = 9
CDs sold in 9 years will therefore be:
= 29,000,000 * ( 1 - 20%) ⁹
= 3,892,314 CDs
