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?
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.

3. Mr. Pau has
some clay with a mass
of 24 kilograms. If he puts the same
amount of clay into 6 bags, how
many grams of clay are in each bag?
A 4,000 grams
1,440 grams
© 144 grams
0 400 grams
Answer:
A. 4,000 grams
Step-by-step explanation:
1 kilogram = 1,000 grams
24 kilograms = 24,000 grams
Mass of clay = 24 kilograms = 24,000 grams
Number of bags = 6
how many grams of clay are in each bag?
Grams of clay in each bag = Total mass of clay / number of bags
= 24,000 grams / 6 bags
= 4,000 grams per bag
Grams of clay in each bag = 4,000 grams

3 A quadrilateral has vertices (-4,-4), (-6, 4), (6,8), and (10, 2). What are
the coordinates of the vertices of the image after a dilation with the
origin as the center of dilation and a scale factor of 3.5? *
O (-14, -14), (-21, 14), (21, 28), and (35, 7)
(-6, -6), (-9,6), (9, 12), and (15,3)
(-10, -10), (-15, 10), (15, 20), and (25,5)
(-12, -12),(-18, 12), (18, 24), and (30, 6)
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)

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?
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

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?
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
[tex] {2}^{2n} \times {2}^{n} \times \frac{2}{16} n[/tex]
solve it without any links. I don't want any links..
Answer:
[tex] \frac{n \times {2}^{3n} }{8} [/tex]
Step-by-step explanation:
1) Take out the constants.
[tex] \frac{2}{16} \times {2}^{2n} \times {2}^{n} n[/tex]
2)Simplify 2/16 to 1/8.
[tex] \frac{1}{8} \times {2}^{2n} \times {2}^{n} n[/tex]
3) Use Quotient rule: x^a/x^b = x^a-b.
[tex] \frac{ {2}^{2n + n} }{8} [/tex]
4) Simplify 2n + n to 3n.
[tex] \frac{ {2}^{3n} n}{8} [/tex]
Hence, the answer is 2^3n n/8
What is the least common denominator for 1/6 and 3/8
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.

Write the expression in Distributive Property form (as a Distributive Property problem). 39d - 13e + 195g
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).

Find the measure of the indicated arc
Answer:
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°.
