Answer:
x = 18 and x = 36
Step-by-step explanation:
let unknown value is x
6:x = 1:3
product of means = product of extremes
6*3 = 1 *x
18 = x
x:30=8:5
product of means = product of extremes
5x=180
x=180/5
x=36

D: 5+4<10
PLS GIVE BRAINLIEST
Answer:
Perhaps option B
Step-by-step explanation:
Suppose a,b,c represent three positive whole numbers. if a+b=13 and b+c=22 and a+c=19 what is the value of c
Answer: C = 14
Step-by-step explanation: You can assume the A is less than B, and if you just go down in numbers such as A=6 and B=7 (To solve A + B = 13), you will eventually get to A=5 and B=8. If you do B = 8 + C = 14 ( That you get after subtracting 8 by 22 ) You should get 22, and to proof check it, you do A + C which is going to be 5 + 14 and you get 19 thus proving that C = 14.

Animals they eat and then release carbon through respiration. Nitrogen is only in the nitrogen cycle, and the only living organisms that can release oxygen are plants because humans and animals cannot photosynthesize. LOL!
8) Eugene borrows $250 at a 4% annual interest rate. If he does not
make any payments, how much simple interest will he owe in 18 months?
A) $10
B) $15
C) $18
D) $20
Answer:
The simplest interest will be $15 ⇒ B
Step-by-step explanation:
The rule of the simple interest is I = Prt, where
P is the initial amountr is the rate in decimalt is the time∵ Eugene borrows $250 at a 4% annual interest rate
∴ P = 250
∴ r = 4% = 4 ÷ 100 = 0.04
∵ The time is 18 months
→ Change the time to year because the rate is annual
∵ 1 year = 12 months
∴ t = 18 ÷ 12 = 1.5 years
→ Substitute the values of P, r, and t in the rule above to find the interest
∵ I = 250 × 0.04 × 1.5
∴ I = 15
∴ The simplest interest will be $15

Is it possible to improve your grade from a "d" to a "b"?
Answer: Of course it is possible if you try your hardest and study
Answer:
Depends
Step-by-step explanation:
Hello! This problem really depends on where you are in the grading period and how many grades are entered in relation to your grade. If you have a D but only have 2 grades then getting a B in the class should be relatively easy. However, if you have a D in a class that you have 15 graded assignments in it will be much harder to raise your grade to a B. Best thing to do is work at this early and try not to let your grade dip throughout the grading semester.
Hope this helps!

10.An object of mass 300 kg is observed to accelerate at the rate of 4 m/s2. Calculate the force required to produce this
acceleration
PLLLLSSSSS HHHHHEEEELLLLPPPP
Answer:
F=Ma
Step-by-step explanation:
force= 300x4
force= 1200N
The Force required to move a mass of 300 kg is 1200 N
What is force?In Physics, force is defined as The push or pull on an object with mass that causes it to change its velocity. Force is an external agent capable of changing a body's state of rest or motion. It has a magnitude and a direction.
Given here, the mass (M) = 300 kg and acceleration = 4 m/s²
Therefore force required to move a body of mass 300 kg is
F=300×4
= 1200N
Hence, the for required to produce this acceleration is 1200N

3. A ladder leaning against a wall
makes an angle of 68° with the
ground. If the foot of the ladder is 4
feet from the wall, how high on the
wall is the ladder, to the nearest
tenth of a foot?
Answer:
tangent 68° = opposite / adjacent
opposite (wall height) = tan (68) * 4 feet
opposite (wall height) = 2.4751 * 4 feet
opposite (wall height) = 9.9004 feet or
9.9 feet (to the nearest tenth of a foot).

1. Matthew decided that he would like to spend his summer working and saving his money. He begins the summer with no money in his account, but he is getting paid $160.00 per week to mow lawns. His brother Dillon began the summer with $345.00 and has decided that he will referee soccer games. He will make $45.00 per week. After how many weeks will Matthew and Dillon have the same amount of money?
the anwer is no matthew will not have the same amount of money
Answer: 3 weeks.
Step-by-step explanation: Matthew's pay goes up by $160 a week, so that's y=160x.
Dillon's pay is $45 a week, but started out with $345. So, that's y=45x+345.
So, they will have the same amount of money after 3 weeks.

a small airplane flies 1 015miles with an average speed of 290 mph. 1.75 hours after the plane leaves, a Boeing 747 leaves from the same point. Both planes arrive at the same time; what was the average speed of Boeing 747?
Answer:
The Boeing 747 had an average speed of 580 mph.
Step-by-step explanation:
Constant speed motion
An object is said to travel at constant speed if the ratio of the distance traveled by the time taken is constant.
Expressed in a simple equation, we have:
[tex]\displaystyle v=\frac{d}{t}[/tex]
Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
From the equation above, we can solve for d:
d = v . t
And we can also solve it for t:
[tex]\displaystyle t=\frac{d}{v}[/tex]
The small airplane travels 1015 miles at a constant speed of v=290 miles/hour. The time it took to arrive its destiny was:
[tex]\displaystyle t=\frac{1015}{290}[/tex]
t = 3.5 hours
The Boeing 747 left from the same point 1.75 hours after the small plane and traveled the same distance. It needed a time t' = 3.5 - 1.75 = 1.75 hours, thus its speed must have been:
[tex]\displaystyle v=\frac{1015}{1.75}=580[/tex]
The Boeing 747 had an average speed of 580 mph.
At the beginning of every gym class, Mr. Gordon leads the class in a warm-up. In today’s warm-up, the class does jumping jacks for 3 minute. Erin does 54 jumping jacks in that time. Mr. Gordon says the class will do jumping jacks 4 minutes tomorrow. If Erin does jumping jacks at the same rate tomorrow, how many will she she do.
Answer:
Erin will do 72 jumping jacks.
Step-by-step explanation:
We divide 54 by 3 to get Erin's per minute ratio
She gets 18 jumping jacks per minute
We then add that to 54 to get her rate if she did for 4 minutes instead
The answer is 72
hope this helped!
Erin will do 72 jumping jacks in 4 minutes.
What is a Ratio?A ratio indicates the number of times one number contains another.
Given that, Erin does 54 jumping jacks in 3 minutes.
Therefore, mathematically:
3 minutes = 54 jumping jacks
1 minute = 18 jumping jacks
4 minutes = 72 jumping jacks
Hence, Erin will do 72 jumping jacks in 4 minutes.
