Answer:
Step-by-step explanation:
Basically angle bisector divides the angle in tow equal parts. As Full angle,
m∠KJI = 76 Degrees
Angle Bisector will divide it into two equal parts means that 76/2=38 Degrees each
m∠KJL=m∠KLI
38=38
Your right answer will be 38.
At carl's combine diner, there are three size of coffee drinks regular (300ml), large (500ml) and extra large (800mL), and they cost $2.25, $3.25, and $5.75, respectively. on a particular afternoon, the diner sold at total of 37 coffees. The total volume of coffee sold was 19,100mL and the amount of money made in coffee sales was $133.25. How many of each size of drink did customers buy that afternoon?
Answer:
The number of regular, large, and extra-large drinks are 12, 15, and 10 respectively.
Step-by-step explanation:
Given that the cost for regular coffee drinks (300 ml)=$2.25
The cost for large coffee drinks (500 ml)=$3.25
The cost for extra large coffee drinks (800 ml)=$5.75
Let p,q, and r be the number of regular, large, and extra-large coffee sold.
As the diner sold a total of 37 coffees, so
p+q+r=37
r=37-p-q...(i)
The volume of p regular coffee = 300p ml
The volume of q large coffee = 500q ml
The volume of r extra-large coffee = 800r ml
As the total volume of coffee sold was 19,100mi, so
300p+500q+800r=19100
By using equation (i)
300p+500q+800(37-p-q)=19100
300p+500q+800 x 37 - 800p - 800q=19100
-500p-300q=19100-29600
500p+300q=10500
500p=10500-300q
p=21-0.6q...(ii)
Now, the cost of p regular coffee=$2.25p
The cost of q large coffee=$3.25q
The cost of r extra-large coffee=$5.75r
As the amount of money made in coffee sales was $133.25, so
2.25p+3.25q+5.75r=133.25
By using equations (1) we have
2.25p+3.25q+5.75(37-p-q)=133.25
2.25p+3.25q+212.75-5.75p-5.75q=133.25
3.50p+2.50q=79.5
From equation (ii)
3.5(21-0.6q)+2.50q=79.5
73.5-2.1q+2.5q=79.5
0.4q=79.5-73.5=6
q=6/0.4
q=15
From equation (ii)
p=21-0.6(15)
p=12
From equation (i)
r= 37-12-15
r=10
Hence, the number of regular, large, and extra-large drinks are 12, 15, and 10 respectively.
LMNO is a parallelogram. If NM = x + 15 and OL = 3x + 5 find the value of x and then find NM and OL.
Answer:
x = 5 unit
NM = 20 unit
OL = 20 unit
Step-by-step explanation:
Given:
LMNO is parallelogram
NM = x + 15
OL = 3x + 5
Find:
x and NM and OL
So,
NM = OL
x + 15 = 3x + 5
2x = 10
x = 5
So,
NM = x + 15 = 5 + 15 = 20
OL = 3x + 5 =3(5)+5 = 20

Answer:
g x 1.99 + 19.99 OR 1.99g + 19.99
Step-by-step explanation:
The cost is 1.99, you multiply 1.99 by the amount of games you are buying (g) to get the total cost. for example:
1 game = 1.99
2 games = 3.98 -> 3.99 (rounded)
3 games = 5.97 -> 5.99 (rounded)
equation:
(2 games)
1.99 x 3 (amount of games) =
step 2
you just add 19.99 for the membership fee
1.99g also equals 1.99 x g because its algebra.. duh

Yesterday I drove 150 minutes at a speed of 100 miles/h. How many miles did I drve?
Answer: 250 miles
Step-by-step explanation:
I am not sure what grade level you are, but this is how it is done in college.
I hope it can give you an idea and be of some help.
First you have to convert 150 minutes to hours. Then you multiply your new hours to 100 miles.
150 minutes x 1 hour x 100 miles = 250 miles
60 mins. 1 hour
Find the True statement
Answer:
B. A triangle can have only 1 right angle.
Step-by-step explanation:
Think of a right angle as an L. If you have an L connecting to a backwards L, you have an open shape. Triangles have 3 sides and are closed shapes. If a triangle has two right angles, you could connect the two ends but that would give you a square or triangle.
Hope this helped!
Answer:
B
Step-by-step explanation:
So there can be only one right angle if all other angles are to be greater than zero

Solve to find the value for x in the linear equation: 3(−4x + 5) = 12.
1. Use the distributive property:
2. Use the subtraction property of equality:
3. Division property of equality:
3(−4x) + 3(5) = 12
−12x + 15 = 12
−12x + 15 − 15 = 12 − 15
−12x = −3
Answer:
Solving the linear equation [tex]3(-4x + 5) = 12[/tex] we get [tex]\mathbf{x=\frac{1}{4}}[/tex]
Step-by-step explanation:
We need to solve to find the value for x in the linear equation: [tex]3(-4x + 5) = 12[/tex]
1. Use the distributive property:
Multiply 3 with terms inside the bracket
[tex]3(-4x + 5) = 12\\3(-4x)+3(5)=12\\-12x+15=12[/tex]
2. Use the subtraction property of equality:
Subtracting 15 on both sides
[tex]-12x+15-15=12-15\\-12x=-3[/tex]
3. Division property of equality:
Divide both sides by -12
[tex]\frac{-12x}{-12}=\frac{-3}{-12}[/tex]
[tex]x=\frac{1}{4}[/tex]
So, solving the linear equation [tex]3(-4x + 5) = 12[/tex] we get [tex]\mathbf{x=\frac{1}{4}}[/tex]

Chuck lives of a mile from the post office. He walked of the way from home to the post office. How far did Chuck walk? If possible, write the answer in reduced form.
Complete question :
Chuck lives 4/5 of a mile from the post office. He walked 2/3 of the way from home to the post office. How far did Chuck walk? If possible, write the answer in reduced form
Answer:
8/ 15 miles
Step-by-step explanation:
Given that:
Distance from house to post office = 4/5 miles
Distance walked = 2/3 of the distance
Hence, the distance walked can be obtained thus :
2/3 of (4/5)
2/3 * 4/5
8 / 15
Hence, Chucks walked 8 /15 miles

Answer:
A.(-1,-1)
E.(4,64)
Step-by-step explanation:
We are given that
Function
[tex]y=x^3[/tex]
We have to find all possible input-output pairs for the function.
Substitute x=-1
[tex]y=(-1)^3=-1[/tex]
Then, the pair is (-1,-1)
Now, substitute x=-2
[tex]y=(-2)^3=-8[/tex]
Then, pair is (-2,-8)
Now, substitute x=3
[tex]y=3^3=27[/tex]
Now, substitute x=4
[tex]y=4^3=64[/tex]
Now, substitute x=1
Then, y=1
Hence, Option A and E are true.
A.(-1,-1)
E.(4,64)
The possible input-output pairs for the function are [tex](-1,-1)[/tex] and [tex](4,64)[/tex]
Input-output relationship:The given function is,
[tex]y=x^{3}[/tex]
When x = -1 then [tex]y=(-1)^{3} =-1[/tex]
When x = 4 then [tex]y=4^{3}=64[/tex]
When x = -2 then [tex]y=(-2)^{3}=-8[/tex]
Hence, the possible input-output pairs for the function are [tex](-1,-1)[/tex] and [tex](4,64)[/tex]
