If the measure of \angle∠4 is 68 degrees,, find the measure of \angle2∠2 in degrees.
Answers
Hi, there! I'd love to help you out!
We know complementary angles add up to 90 degrees.
Let's say our first angle is x:
x = first angle
It tells us the other angle is 68 degrees more. So we are just adding 68 to our other angle:
x = first angle
x + 68 = second angle
Now add the two and set it equal to 90 degrees:
x + x + 68 = 90
2x + 68 = 90
-68 -68
2x = 22
/2 /2
x = 11 first angle
x + 68 = 11 +68 = 79 degrees second angle

The owner of a small restaurant bought 75 kilograms of rice. Each week, the restaurant uses 4.5 kilograms of rice.
Function `r` gives the remaining amount of rice, in kilograms, as a function of the number of weeks since the restaurant owner bought the rice.
Solve the equation `r(w)=30`and explain what the solution means in this situation.
Answers
Answer:
r(t) = 75 kg - (4.5 kg/wk)w
Step-by-step explanation:
Let r(t) represent the amount of rice remaining after w weeks.
Then:
r(t) = 75 kg - (4.5 kg/wk)w
please mark as brainliest
Answer:
w=10 and this means that 10 weeks after the rice was bought, 30 kilograms of rice remain.
Step-by-step explanation:
r(w)=75-4.5w is an equation for this function so I'll be using this. First insert r(w)= 30 into the equation.
75-4.5w=30
75-75-4.5w=30-75
-4.5w=-45
-4.5w/-4.5 = -45/ -4.5
w=10

which is the measure of ∠DBC?
Answers
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

Find the volume...!!!
Answers
Answer:
volume = 143.1 m^3
Step-by-step explanation:
here's your solution
=> volume of cuboid = area of base * height
=> volume = 53*2.7
=> volume = 143.1 m^3
hope it helps
Answer is below. Look at the explanation to understand my answer.
To find the volume, you simply multiply all the lengths up to get your answer.
The formula is for finding the volume of a rectangular prism is: L × W × H. Normally there is 3 lengths, but there is only 2. We can still solve by using the same formula, instead of L × W × H, the formula will be Base Area × Height or BA × H.
Here is a breakdown: Solving for a Cuboid (rectangular prism) is easy; all you need to do is multiply all the units.
With that being said...
53 times 2.7 is 143.1 m²
Therefore, 143.1 is the volume
Let me know of questions or concerns about my answer.
Formulas:
V = L × W × H (Length × Width × Height)
V = BA × H (Base Area × Height)

A basketball game a team made 52 successful shots they were a combination of 1- and 2- point shots the team scored 86 points in all write and solve a system of equations to find the number of each type of shot
Answers
Answer: 15
Step-by-step explanation:
x = one point shots
y = two point shots
1) Setup your equations.
x + y = 52
x + 2y = 89
2) Isolate a variable.
x = 52-y
3) Plug in.
(52-y) + 2y = 89
52 +y =89
y=37
4) Solve for x.
x = 52 -37
x=15
5) Check your answer.
15 + 2(37) = 89
15+74=89
89=89
37+15 = 52
52=52
x = one point shots
y = two point shots
1) Setup your equations.
x + y = 52
x + 2y = 89
2) Isolate a variable.
x = 52-y
3) Plug in.
(52-y) + 2y = 89
52 +y =89
y=37
4) Solve for x.
x = 52 -37
x=15
5) Check your answer.
15 + 2(37) = 89
15+74=89
89=89
37+15 = 52
52=52

Identify the x- and y-intercept and graph the equation on the coordinate plane to the left. What is the x-value when y is 3? Answer these questions in the text box below.
Answers
Answer:
x-int is 24/5 y-int is 8 and x value when y is 3 is 3
Step-by-step explanation:
So for the x int, we can plug in 0 for y, because in a x intercept, the y is zero.
5x=24
x=24/5
for the y int, we can plug in 0 for x, because in a y intercept, the x is zero.
3y=24
y=3
now when y is 3, we can just plug that in.
5x + 3 times 3 = 24
5x+9=24
5x=15
x=3

Charlotte recorded the number of minutes she spent exercising in the past ten days: 9, 13, 5, 2, 9, 1, 14, 3, 5, 7. Find the median of the data.
Answers
Answer:
The median is 7.
Step-by-step explanation:
In order to find the median, you need to ut the numbers in either least to greatest form, or greatest to least (FIRST).
I'm gonna do both as an example.
Greatest to least:
14, 13, 9, 9, 7, 5, 3, 2, 1
Least to greatest:
1, 2, 3, 5, 7, 9, 9, 13, 14
It is REALLY important that you use ALL of the numbers you are given, even if there are two or more of the same number.
The next thing you need to do is find the number that is in the middle.
It will be the same for both least to greatest AND greatest to least.
You can either count one from either side, going in a pattern, OR you can count how many there is, divide it by 2, and whatever answer you get, count that many times over from one side.
In this case, your answer goes like this:
since there are 9 numbers, and 9 is not an even number, you will have only one median. Having 2 medians IS normal and it IS ok.
In this case, you want to go down one number (from 9) and divide that. So you do 8 divided by 2, which is 4. Count that many times over and you have your answer, 7.
I hope this helped you!
Have a great dayyyy
