PLS HELP WILL GIVE BRAINLIEST!! Identify this set of lines as parallel, perpendicular, or neither.
Answer:
Perpendicular
Step-by-step explanation:
You know if two equations are perpendicular if their slopes are the reciprocals of each other. -4/3 and 3/4 are reciprocals, therefore they are perpendicular (y-intercept doesn’t matter in perpendicular equations).
((It’d only be parallel if the slopes were exactly the same and the y-ints were different.))

Bruce drove 360 miles in 6 hours. If he continues at a consistent speed, how many more hours would he need to drive another 300 miles?
Answer:
5 hours
Step-by-step explanation:
If he drove 360 miles in 6 hours, that means he drives 60 miles per hour.
300 divided by 60 is 5, so he will need to drive for 5 more hours
Answer:
5 hours
Step-by-step explanation:
Find his speed in miles per hour:
360/6
= 60
So, his speed is 60 mph
To find how many more hours he would have to drive another 300 miles, divide 300 by 60:
300/60
= 5
So, he would have to drive 5 hours

On last week's math test, 32 students received passing grades and 16 students did not
receive passing grades. What is the ratio of the number of students who passed the test to
the total number of students who took the test?
A
11 / 1
B
2/3
C
3/2
D
2/1
Answer:
Option B. The ratio of the number of students who passed the test to
the total number of students who took the test is 2/3
Step-by-step explanation:
Firstly, we have to find the total number of students who took the test, we can do that by adding the number of students who passed and the number of students who did not pass, so ...
32 + 16 = 48
Now we just write down the ratio between the number of students who passed the test and the total number of students who took the test. So we get
32/48
Now we just simplify and get...

Select all the expressions that represent a price discounted by 20% of the price of an item that originally cost d dollars
Options :
A. 0.8d
B. d-0.2
C. d-0.2d
D. 1-0.2d
Answer:
A. 0.8d ; d - 0.2d
Step-by-step explanation:
Given that:
Cost of item = d dollars
Discount on items = 20%
Expression represemting the discounted price :
(100% - 20%) x d
80% * d
0.8d
(100% - 20%) x d
(1 - 0.2)d

express in the form 1:n give n as a decimal 8:6
Answer: 8.6:8.6
Explanation:
1:n is the form you want.
n is 8.6. change the n value so it is 1:8.6
1 is 1 times bigger than 8.6
8.6 times 1 is 8.6
so you've got 8.6:8.6

In ΔEFG, f = 42 inches, e = 39 inches and ∠E=43°. Find all possible values of ∠F, to the nearest degree.\
Answer:
The angle F = 47.25°
Step-by-step explanation:
Step(i):-
Given that f =42inches and e = 39 inches
Given that ∠E = 43°
By using sine rule
[tex]\frac{a}{sinA} = \frac{b}{sinB} = \frac{C}{sinC} = 2R[/tex]
[tex]\frac{e}{sinE} = \frac{f}{sinF}[/tex]
⇒ [tex]\frac{39}{sin43} = \frac{42}{sinF}[/tex]
Cross multiplication , we get
⇒ 39 sin F = 42 × sin 43°
[tex]sin F = \frac{42 X 0.68199}{39}[/tex]
⇒ sin F = 0.734459
Step(ii):-
⇒ sin⁻¹ (sin F)= sin ⁻¹ ( 0.734459)
⇒ F = 47.25
The angle F = 47.25°

There are 42 boys and girls participating in an essay-writing competition. Of the competitors, 21 are in seventh grade, 14 are in eighth grade, and 7 are in ninth grade. What is the probability of an eighth grader winning the competition? Which simulation(s) can be used to represent this situation?
A.
The probability is . Simulate this situation by rolling a 6-sided die, with odd numbers representing seventh graders and even numbers representing eighth graders.
B.
The probability is . Simulate this situation by picking a card from a deck of cards, with hearts representing seventh graders, diamonds representing eighth graders, and spades representing ninth graders.
C.
The probability is . Simulate this situation by spinning a spinner with six equal sections, with one section representing ninth graders, two sections representing eighth graders, and three sections representing seventh graders.

Accordingly to the Internet which knows everything a good rule of thumb is to plan for 5 to 10% waste when buying carpet how did the estimate to do
Answer:
Not bad
Step-by-step explanation:
According to the internet, there are a number of factors to consider before estimating your waste percentage when buying carpets.
You may have to check the shape of your room, if it has multiple walls or if it is just complicated. For this kind you can estimate a 20% waste factor.
But for uncomplicated rooms having the same width as the carpet, the rule of thumb is to add a 10% waste factor to the square footage area.

1/2(12x + 18) > 99
Step 2: Solve for x
[Multiplication Property of Equality] Multiply 2 on both sides: 12x + 18 > 198[Subtraction Property of Equality] Subtract 18 on both sides: 12x > 180[Division Property of Equality] Divide 12 on both sides: x > 15Here we see that any value x greater than 15 would work as a solution to the inequality.

Step-by-step explanation:
the area of the whole box is 17,280 cubic units because 24x24x30=17,280. If each cubic unit is .004 lbs then multiply 17,280 by .004. And it equals 69.12 lbs. And 69 is bigger than 30, so no he cant lift it.

Let's say you have a bag with 16 cherries, 12 sweet and 4 sour. If you pick a cherry at random, what is the
probability that it will be sweet? Write your answer as a reduced fraction
Help pls
Answer:
3/4
Step-by-step explanation:
12 sweet/ 16 total
first lets divide both by 4
(12÷4) / (16÷4)
3/4
that is how we got that.
Tell me if this helps
If you pick a cherry at random, the probability that it will be sweet will be 3/8.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event. In everyday life, risk modeling and assessment involve the use of probability theory. Environmental control, entitlement analysis, and financial regulation are all areas where governments use probabilistic methodologies.
It is given that the bag has 16 cherries, 12 sweets,s and 4 sours.
The total number of the quantities bag is the sum of all the quantities,
=16 +12+ 4
=32
The probability that it will be sweet is the ratio of the number of sweet to the total number of quantities,
= 12 / 32
=3 / 8
Thus, if you pick a cherry at random, the probability that it will be sweet will be 3/8.
