Answer:
k=45
Step-by-step explanation:
45+2k+k=180
Step 1: Simplify both sides of the equation.
45+2k+k=180
(2k+k)+(45)=180(Combine Like Terms)
3k+45=180
3k+45=180
Step 2: Subtract 45 from both sides.
3k+45−45=180−45
3k=135
Step 3: Divide both sides by 3.
3k/3=135/3
k=45

A slug travels 3 centimeters in 3 seconds. A snail travels 6 centimeters in 6 seconds. Both travel at constant speeds. Mai says, “The snail was traveling faster because it went a greater distance.”
Answer:
Mai is wrong since both travel the same distance in the same amount of seconds
Step-by-step explanation:
3 centimeters in 3 seconds is 1 centimeter a second for the slug
6 centimeters in 6 seconds is 1 centimeter a second for the snail
so both travel the same distance
Answer:
No, she is wrong. They are both going the same pace.
Step-by-step explanation:
3 centimer divided by 3 is 1. 1 cm a second. 6 centimeters didvided by 6 is 1.
1 cm a second. Hence they are both going the same speed. If you don't understand anything comment and ill explain more. Please heart and 5 stars and brainlest if you don't mind

4(x-1)=-8 how do i answer this
Answer: x= -1
Step-by-step explanation:
4(x-1)=-8
First distribute
4x-4=-8
Now add 4 to -8
4x=-4
Now divide by 4
X=-1
The answer is x = -1
Step-by-step explanation: When it comes to solving for a variable (x) you have to distribute if there is parenthesis and then use inverse operations to get the answer.
4(x-1)=-8 Distribute
4x - 4 = -8 Subtract 4 from both sides
4x = -4 Divide 4 on both sides
x = - 1 and that is your answer

6. In case of short
circuit............current will flow in
that circuit. *
Answer:
As suggested in the name itself:
a short circuit makes the circuit 'short' which causes the resistance of the circuit to be close to none
When the resistance is decreased, the amount of current flowing in the circuit increases (ohm's law: R ∝ 1/ I)
Therefore, in case of a short-circuit. More current will flow in the circuit

Step-by-step explanation:
A consumer wanted to compare two types of battery storage. One type is refrigerated and the other is room temperature. It is a common belief that refrigerated batteries last longer. This belief is tested by placing 10 fully charged batteries into each type of storage and then measuring the percentage of charge remaining after thirty days. A coin tip was used to determine which type of storage each battery would be placed in first. Results indicated that there was no difference in the two types of storage Complete parts (a) through in below.
What type of experimental design is this?
A) Matched pairs design
B) Completely randomized design
C) Randomized block design
D) Case-control study
Answer:
A) Matched pairs design
Step-by-step explanation:
In experimental design, the match pairs experimental design is one that often involves only two treatment conditions; which in this case are the 'refrigerated and the room temperature battery storage types'.
Thus, these two treatment conditions form a matched pair because we are told that 10 fully charged batteries are placed into each type of storage.

Janet can make 4/5 of a necklace in 20 minutes. At this rate, how many necklaces, to the nearest tenth of a necklace, can Janet make in 1 hour?
Answer: 4 necklaces
Step-by-step explanation: 4/5 x 5 = 4
hope this helps
Answer:
Janet makes 2.4 necklaces in 1 hour
Step-by-step explanation:
first you need to find how many minutes it takes to make one necklace.
to do this, divide 20 by 4 and multiply by 5.
20/4 = 5
5 * 5 = 25
janet makes one necklace every 25 minutes.
one hour is 60 minutes.
60/25 = 2.4
What is 200 as a percent?
Answer:
Step-by-step explanation:
So, we know that 200 can also be written as 200.00 which does not change the value of the number. Now, we can turn it into a percentage by moving the decimal point to digits back: 200.00 --> 20000. So, this means that 200 is 20000%.
