Alice has just discovered base 10 cake! She is delighted with how powerful it is. One day, after nibbling on the cake, Alice realizes she is 1 mile tall. Having her head in the sky makes her think about space travel. She decides she wants to visit the moon, which is about 239,000 miles from the earth. How many more ounces of base 10 cake should Alice eat so the top of her head just touches the moon? Give your answer to the nearest hundredth of an ounce.
Answer:
5.38 ounces
Step-by-step explanation:
Given that :
Alice height = 1 mile
Distance of earth to moon = 239000 miles
Number of base 10 cakes required so they Alice's head just touches the moon ;
Using the relation :
Distance = height per ounce * 10^number of ounces
Height per ounce = 1 mile ;
Let number of ounces = n
Hence,
239000 = 1 * 10^n
239000 = 10^n
Take log of both sides
Log(239000) = n
5.3783979 = n
5.3784 = n
Hence, Alice should take 5.38 ounces of base 10 cakes

Find the measure of the numbered angle.
m∠5 =
Answer:
40°
Step-by-step explanation:
180- (90 + 40) = 50°
Angle 1 = 50°
180 - 50 = 130°
Angle 2 = 130°
180 - 130 = 50°
Angle 3 = 50°
180 - (90 + 50) = 40°
Angle 5 = 40°
OR
the two triangles are similar. Therefore, their angles are congruent. Since the tringle was only flipped and made slightly smaller, angles 9 and 5 are corresponding angles. (Both have the same measure of 40°)
Hope this helps. Have a nice day

Given f(x) = -3x + 3, solve for x when f(x) = 9.
Answer:
x = -2
Step-by-step explanation:
f(x) = -3x + 3
f(x) = 9
-3x + 3 = 9
Subtract 3 from both sides;
-3x = 6
Divide both sides by -3
x = -2

Given lines p and q are parallel, find the value of x that makes each diagram true.
Answer: for a the answer is 140° and for b x=25°
Step-by-step explanation:
for a, when you have 2 parallel lines cut by a transversal,the corresponding angles are congruent. and the angle140 is congruent to the corresponding angle as they are vertical angles are congruent.
for b, angle x is congruent to the angle that is supplementary to 155 therefore 180-155=25°
In a paint factory, an old conveyer line has filled 40 barrels of paint, and is filling more at a rate of 1 barrel per minute. A worker just switched on a newer line that can fill 3 barrels per minute. In a little while, the two lines will have filled an equal number of barrels. How many barrels will each line have filled?
Write a system of equations, graph them, and type the solution.
Answer:
5 minutes
Step-by-step explanation:
let the time after which two lines will have filled an equal number of barrels is 'X' minutes.
so, according to the question after 'X' minutes;
⇒ number of barrels in old conveyer line = number of barrels in new conveyer line
⇒ 40x + 2X = 10X
⇒ X = 5
Left on together the cold and hot water faucets of a certain bathtub takes 6 minutes to fill the tub. If it takes the hot water faucet 15 minutes to fill the tub by itself , how long will it take the cold water faucet to fill the tub on its own ?
Answer:
10 minutes
Step-by-step explanation:
We have
1/ hot water faucet + 1/ cold water faucet = 1/6
= 1/15 + 1/c = 1/6
1/c = 1/6 - 1/15
Lowest Common Denominator
= 30
Hence:
1/c = 5 - 2/30
1/c = 3/30
1/c = 1/10
Cross Multiply
c = 10 minutes
Hence, it will take the cold water faucet 10 minutes to fill the tub on its own

Della went to the market to buy 4.5 pounds of sliced fruit in a container. She paid with a $20 bill and a $5 and received $4.67 as change. She paid $1.62 in taxes and for the fruit. What was the cost for one pound of sliced fruit before taxes
Answer:
the cost for one pound before taxes is $4.52
Step-by-step explanation:
The computation of the cost for one pound before taxes is shown below:
= Paid a bill + amount - change amount
= $20 + 5 - $4.67
= $20.33
Now the cost of one pound would be
= Total amount ÷ number of pounds purchased
= $20.33 ÷ 4.5 pounds
= $4.52
Hence, the cost for one pound before taxes is $4.52
Samantha Villegas is making pupusas to raise funds for the 9th grade academy. She goes to numero uno market with $12 to buy some ingredients. Samantha gets flour that cost 7.45. She also needs cabbage to make the curtido the cabbage cost 85 cent per pound. How many pounds of cabbage, for curtido could Samantha buy ?
Answer:
Money she has = 12$ = 12*100 = 1200 Cent
cost of flour = 7.45 $ = 745 Cent
Remaining money = 1200-745 = 455 Cent
cost per pound of cabbage = 85 Cent
Total pound of cabbage that can buy = 455/85 = 5.35 pound

Joe earns $425 a week for working 40 hours and an additional $20 an hour for each hour over 40. Last week, Joe made $485. Write and solve an equation to determine how many hours over 40 he worked. (Don't forget to define your variable and answer in a complete sentence.) How many total hours did Joe work last week?
Answer:
Joe worked 3 hours overtime.
Step-by-step explanation:
Let t = number of hours overworked
425 + 20 × t = 485
425 + 20t = 485
20t = 485 - 425
= 60
[tex]\frac{20t}{20} = \frac{60}{20}[/tex]
t = 3
[tex]\therefore[/tex] Joe worked 3 hours over time.

Please help me with circle theorems
Answer:
x = 38°, y = 68°, z = 55°
Step-by-step explanation:
This would be easier to explain if the vertices were labelled , however
Angles at the circumference of the circle subtended on the same arc are congruent.
x and 38 are subtended on the same arc
y and 68 are subtended on the same arc
z and 55 are subtended on the same arc
Thus
x = 38°, y = 68° and z = 55°
