Step-by-step explanation:
which is the measure of ∠DBC?
Answer: 20°
Step-by-step explanation:
There is 180 degrees in the triangle. ∠C is 50°, ∠A is 80°, ∠B is 30°, and the total adds up to 160°, so 180-160 equals 20.
Answer: 20 degrees
Step-by-step explanation: if you add up the angles of any triangle, the sum should always be 180. so add up angle A and angle C :
80 + 50 = 130
subtract that from 180 to find out what angle ABC is:
180 - 130 = 50
since we know that angle ABD is 30 degrees, all we have to do now is subtract that from 50:
50 - 30 = 20
angle DBC = 20 degrees
Determine whether these two triangles are similar, and if so what is the ratio of their sides?
Yes, ratio = 3/4
Yes, ratio = 3/8
Yes, ratio = 4/5
No, these triangles are not similar
Answer:
No, these triangles are not similar.
Step-by-step explanation:
If they were similar by ratio you would be able to divide 3/8 and 4/10 and get the same decimal but instead you get 0.375 for 3/8 and 0.4 for 4/10.

Answer:
1256, 125.6 (this is wrong sorry i didn't know that it wasn't a full circle)
Step-by-step explanation:
A) The area that the sprinkler is spraying is in a circle with a radius of 20 ft. The formula to find the area of a circle is pi*r^2, so the area of this circle will be 400pi (substitute 20 for r). Pi in this problem is 3.14, so 400*3.14 is 1256 feet.
B) The perimeter of the spray is technically just the circumference of the circle. The circumference is 2r*pi, so we substitute 20 for r again and we get 40pi. Again, pi is 3.14 in this problem, so 40*3.14 is 125.6 feet.

January 16, 2009, was one of the coldest days in recorded history in the US. The temperature on the Big Black River in Maine was recorded at 50 degrees below zero Fahrenheit. How could you represent that temperature with an integer?
Answer:
Okay, so, input this in your search bar on YT: Understanding integers using temperature
Step-by-step explanation:
And it's been quite a while since I've done integers, but I hope this helps! :)
Answer:
-50 degrees F
Step-by-step explanation:
Zero is the point on the number line where numbers to the left of zero are negative, and numbers to the right are positive. 50 degrees below zero = 50 degrees less than zero, so -50 degrees.

A traveler takes a taxi from the airport to a hotel. The taxi driver charges $1.90 initial charge plus $1.25 per mile. Which equation can be used to find y, the total cost of the trip, if x represents the number of miles of the trip?
$1.90 + $1.25 x X = Y?
hope this helps I'm not sure
Step-by-step explanation:
This is a linear function with initial value $1.90 and slope $1.25/mile:
total cost = $1,90 + ($1.25/mi)x

Find the value of x - this is circle segments.
Answer:
x = 12
Step-by-step explanation:
Given a tangent and a secant from an external point to the circle, then
The square of the tangent is equal to the product of the external part of the secant and the entire secant, that is
x² = 8(8 + 10) = 8 × 18 = 144 ( take the square root of both sides )
x = [tex]\sqrt{144}[/tex] = 12

Can someone answer this its just boxplots :)))
Explanation:
The boxplot, aka box-and-whisker plot, is a visual way to represent summary data. Each piece of the boxplot visually tells us one of the five items of a five number summary, which are:
Min = smallest valueQ1 = first quartileMedian = middle most valueQ3 = third quartileMax = largest valueThe median is the vertical line inside the box of the boxplot. The diagram shows that the median is 25. Exactly half of the distribution is below the median, and the other half is above the median. So that means that 50% of the cars get at least 25 mpg.

The Jackson family is driving from Boston to New York for a summer vacation trip. So far, they have driven 84 miles which is 40% of the total miles of their trip. How many miles is the Jackson’s trip from Boston to New York?
Explain how you solved this problem in the box below. Include a description of your strategy and your answer in your explanation.
Answer:
84 is .4 of the trip
40% times 2.5 is 100% (40+40+20)
so, multiple 84 by 2.5 and that's the answer
84 * 2.5= 210
Answer:
84 is .4 of the trip
40% times 2.5 is 100% (40+40+20)
so, multiple 84 by 2.5 and that's the answer
84 * 2.5= 210

what is the peremiter of DEFG
Answer:
The answer is 22 units
Step-by-step explanation:
To find the perimeter we have to add all sides units. So, it length is 7 units and breadth is 4 units, so 7+7=14 and 4+4=8 , and then we will add the l and b , so 14+8=22
the function F is defined by F(x) 12/x+1/2. use this formula to find the following values of the function. F(a/2)
Answer:
F([tex]\frac{a}{2}[/tex]) = [tex]\frac{24}{a} +\frac{1}{2}\\[/tex]
Step-by-step explanation:
so basically what you want to do is insert the f(x) value into the equation. What I mean by that is in this equation, since f(x) = f(a/2), you want to substitute A/2 into the equation, so you'll have [tex]\frac{12}{\frac{a}{2} }[/tex], if you can't see that, its 12/a/2. In other words, this is 12 ÷ [tex]\frac{a}{2}[/tex] , which you can also format as 12 ·[tex]\frac{2}{a}[/tex], because of the "keep, change, flip" thing. Well, you know that equation is equal to 24/a so you just have to add back the 1/2, and you have your answer!
Side Note:
I know the format is terrible, but the answer is right so please bear with me :)I know the person asking this question asked it a year ago so i'm just answering it for future usersIf i'm guessing correctly, this question originated from RSM, and I found it googling rsm problems, and my answer is correct in RSM, so if you have this same question on your RSM homework, I promise you it's rightIf you got this from RSM homework, and you have other questions about the same types, like 7abcdegi, comment, because I have those answers tooIf you have any questions about this answer, also comment, I would love to helpIf the user who asked this question is still active, I would really appreciate brainliest if you think this deserves itHope this helps!!

Andre is making paper cranes to decorate for a party. He plans to make one large paper
crane for a centerpiece and several smaller paper cranes to put around the table. It takes
Andre 10 minutes to make the centerpiece and 3 minutes to make each small crane. He will
only have 30 minutes to make the paper cranes once he gets home.
1. Andre wrote the inequality to plan his time. Describe what , , 10,
and 30 represent in this inequality.
2. Solve Andre’s inequality and explain what the solution means.
Answer:
10 + 3x </= 30
x </= 6.666
He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.
Step-by-step explanation:
10 + 3x </= 30
10 is the minutes for the centerpiece
3 is the minutes to make each small crane
x is the number of small cranes he can make
he has less than or equal to 30 minutes to complete them.
10 + 3x </= 30
subtract 10 from both sides
3x </= 20
x </= 6.666
He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.
