Step-by-step explanation:
The slope of two parallel lines is the same. As long as the y-intercept is different then, the lines are parallel. Therefore, if the slope of line b is [tex]\frac{-5}{9}[/tex] then the slope of line c must also be [tex]\frac{-5}{9}[/tex].

Answers
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

Samantha Villegas is making pupusas to raise funds for the 9th grade academy. She goes to numero uno market with $12 to buy some ingredients. Samantha gets flour that cost 7.45. She also needs cabbage to make the curtido the cabbage cost 85 cent per pound. How many pounds of cabbage, for curtido could Samantha buy ?
Answers
Answer:
Money she has = 12$ = 12*100 = 1200 Cent
cost of flour = 7.45 $ = 745 Cent

cost per pound of cabbage = 85 Cent
Total pound of cabbage that can buy = 455/85 = 5.35 pound

Answers
Answer:
72 right handed batters.
Step-by-step explanation:
45/5=9
8*9=72
45:72=5:8
Hope this helps.
Answer:
a) 72 right-handed batters
b) 5:13
Step-by-step explanation:
This is the answer because:
1) For problem a, we can see that 5 x 9 = 45. In order to balance the ratio, we also have to mulitply the 8 with a 9:
8 x 9 = 72
Therefore, the answer is 72 right-handed batters.
2) For b, there are two ways to do it. Sine we know that there are 5 left-handed batters, we just add 5 + 8 = 13. Therefore, the simplest form of the ratio is 5:13. Another we can do it is by adding 45 + 72 = 117 (total batters). Then, 45 of them are left-handed batters which means the ratio is 45:117 = 5:13.
Therefore, the answer is 5:13.

Answer:
Measure of DE is 12
Step-by-step explanation:
Here, we want to get the measure of DE
We have two similar triangles here
BDE and BAC
if two triangles are similar, then the ratio of their sides are same
Thus, in this case, we proceed as follows;
Now, since DE cuts each side into half;
we can have AB as 2y; then BD as y
Thus, we have that;
BD/DE = AB/AC
y/4x + 4 = 2y/x + 36
2y(4x + 4) = y(x + 36)
2(4x + 4) = x + 36
8x + 8 = x + 36
8x-x = 36-8
7x = 28
x = 28/7
x = 4
recall;
DE is 4x + 4
insert x = 2
DE = 4(2) + 4
DE = 12

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 ?
Answers
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

Answers
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°)

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°
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.
Answers
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
