Answer:
C. 27
Step-by-step explanation:
If those two triangles are similar then look at how much one side is being increased to the other triangle. ML is similar to PQ and it increases by 1.5 to get there.
So find the side similar to RQ which is LN
1.5(x+7)=2x+5
1.5x+10.5=2x+5
5.5=0.5x
x=11
Then plug in 11 for x to find RQ which will be 27

What is the area of the semicircle (use 3.14 for p)?
Please help! Will mark brainlyest.
Answers
Answer:
127.17 cm²
Step-by-step explanation:
Area of a semicircle: 1/2*π*r²π (pi) = 3.14r (radius) = d (diamater) / 2 => 18/2 = 9 cmA = 1/2*π*r²
A = 1/2*3.14*9²
A = 1/2*3.14*81
A = 3.14*40.5
A = 127.17 cm²
Therefore, the area of the semicircle is 127.17 cm²
Hope this helps!
Answer: the first option: 127.17cm2
Step-by-step explanation:
1. divide the diameter in half to get the radius.
2. multiply the radius squared by pie
3. divide that answer in half
so:
9*9=81
81*3.14= 254.34
254.34/2= 127.17

Joe wants to make a epecial cleaning mixturefor his hardwood floors. He needs 3/4 cup of vinegar,2/4cup of clorox and 1/4 cups of water. How much cleaner does Joe have when he is finished makeing the mixture?
Answers
Answer: 1 1/2.
Step-by-step explanation: Joe is using 3/4 cup of vinegar, 2/4 cup of Clorox, and 1/4 cup of water to make a special cleaning mixture right? He's going to mix all of those ingredients together, which means that this is an addition problem. When we add 3/4, 2/4, and 1/4 cups, we add the numerators to get our answer:
3/4 + 2/4 + 1/4 = 6/4, or 1 2/4, or 1 1/2 cups of cleaner in total when we simplify.
Therefore, the total amount of cleaner he makes is 1 1/2 cups.

Savannah decides to research the relationship between the length in inches and the
weight of a certain species of catfish. She measures the length and weight of a number
of specimens she catches, then throws back into the water. After plotting all her data,
she draws a line of best fit. Based on the line of best fit, what would you predict to be
the length of a catfish that weighed 36 pounds?
Answers
Using the line of best fit, it is found that the predicted length of a catfish that weighed 36 pounds is of 36 inches.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, the line passes through points (20,4) and (29,22), hence the slope is given by:
m = (22 - 4)/(29 - 20) = 2.
Then:
y = 2x + b.
Point (20,4) is replaced in the equation and used to find b, hence:
4 = 2(20) + b
b = -36
Then the equation is given by:
y = 2x - 36.
When the weight is of 36 pounds, x = 36, hence the prediction is of:
y = 2(36) - 36 = 36 inches.

Math question, me need help
Answers
Answer: Idealistically, you can write many numbers here, but for the sake of simplicity, I'll say... -7.60.
Step-by-step explanation: This isn't much in terms of written work, it's more mental math. When we're looking for a number greater than a negtaive number, but it still has to be negative, it will be less than the first number. So, what can be less than -7.81, anything -7.80 and above before you get to -7. The higher the number in the negative scale, the smaller it is. The lower the number on the negative scale, the larger it is. So make the number larger than -7.81, and less than -7.

what distance is travelled by a bus that travels at 105kph in 5 hours
Answers
Answer:
21mph = 33.80 km/h
Step-by-step explanation:
Speed = Distance / Time = 105 kph / 5 hours = 21 mph = 33.80 km/h
What is the distance traveled by the bus at a speed of 105 kph in 5 hours?
Answer:The distance traveled by the bus is 525 kilometers.
Step-by-step explanation:As per the provided information in the given question, we know that the speed is given by 105 kph. The time is given by 5 hours. In this problem, we are tasked to find the distance traveled by the bus.
To do this, we will use the formula below:
[tex]\large\begin{aligned}\bigstar\:\boxed{\rm{\: Distance = Speed \times Time \:}} \end{aligned}[/tex]
Substitute the given values into the formula given above and solve for Distance:
[tex]\large\begin{aligned}\rm:\implies{Distance}& = \rm{Speed \times Time} \\\rm:\implies{Distance} & =\rm{105\: kph \times 5\: hrs} \\\rm:\implies{Distance} & =\rm{525\: km} \end{aligned}[/tex]
Hence, the distance traveled by the bus is 525 kilometers.
