Answer:
Step-by-step explanation:
Let
'x' the price of the meal
15% of x or 0.15x is the tip
x + 0.15x = 20.70
1.15x = 20.70 divide both sides by 1.15
x = 20.70/1.15
x = $18
0.15*18 = $2.70
The price of the meal without the tip is $18.
The tip was $2.70.

Answer:
90
Step-by-step explanation:
Because angles opposite congruent angles in a triangle are congruent, the triangle is isosceles.
The altitude drawn from the vertex angle of an isosceles triangle is the perpendicular bisector to the side it is drawn.
So, y=90.
Find the value of y
pls let me know how u solve this
Answer:
X° = 45°
Y = 8√2
Step-by-step explanation:
Angle of this triangle 45°:45°:90° so ratio of the triangle = 1:1:√2
8:8:8√2

Answer:
The price ticket that we know is the adult ticket. The coupon shows that the ticket is good for $28.00. In the redd it shows that you save 4 dollars, so just add 4 to the 28 and the ORIGINAL price of the adult ticket is $32.00.
To find the price of the children's tickets, start with subtracting $28 (this is the price of the adult ticket) from the total of $76 (this is the total number of all the tickets combined).
76 - 28 = 48
Now divide that by 2
48/2 = 24$
So it was $24 per child

Stacy wants oil for the cake pops and cupcakes for her birthday party. She needs 1/2 of a cup of vegetable oil for the cake pops and 1.5 times as much oil for the cupcakes. If Stacy has 2 1/2 cups of vegetable oil, how much will she have left over after she makes the cake pops and cupcakes
Answer:
1 1/4
Step-by-step
The oil left over after she makes the cake pops and cupcakes is 1.25 cups.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, Stacy wants oil for the cake pops and cupcakes for her birthday party.
She needs 1/2=0.5 of a cup of vegetable oil for the cake pops and 1.5 times as much oil for the cupcakes.
So, oil required to make cupcakes is 1.5 ×1/2
= 1.5/2
= 0.75
Stacy has [tex]2\frac{1}{2}[/tex] =2.5 cups of vegetable oil
Total vegetable oil used =0.75+0.5
= 1.25 cups
Oil left over is 2.5-1.25=1.25
Therefore, the oil left over after she makes the cake pops and cupcakes is 1.25 cups.

When the expression representing the parent radical function is multiplied by , the resulting graph is a
of the parent function.
When the expression representing the parent radical function is multiplied by a positive value that is not equal to 1, the resulting graph is a
of the parent function.
Answer:
The first one is reflection because reflection means multiplying the function by a negative constant k the K in this question is representing the -1
The second one is dilation which means to multiply a function by a value of K , that's greater than 1 vertically stretches the function away from the x- axis .
1. Reflection
2 .Dilation
Step-by-step explanation: I just took the test .
Answer:
1. Reflection

Aicha has 36 dress. She completes 1/2 of the dresses in 3/4 of an hour.If she continues at this rate what fraction of the dresses will she complete in one hour?
Answer:
2/3
Step-by-step explanation:
1/2 dresses = 36x1/2 = 18
18 dresses in 3/4 hr. ==> 1/4hr ==> 18/3 = 6
1hr ==> 6x4 = 24
fraction = 24/36 = 2/3
Twenty five more than twice a number is fifty five. What is the number?
25 + 2x = 55
2x = 30
x = 15
The number is 15
Answer:
Step-by-step explanation:
If the number is 15 then twice is 30 then add 25 = 30 + 25 = 55
Prove that the sum of the squares of the lengths of the medians of a triangle is three fourths the sum of the squares of the lengths of the sides.
Answer:
3[|AB|² + |BC|² + |AC|²] = 4[|AD|² + |BE|² + |CF|²]
Step-by-step explanation:
I've attached an image showing a triangle divided into it's medians.
Now, from the attached image, we see that AB, BC & CD are the lengths of sides of triangle while AD, BE & CF are lengths of the 3 medians of the triangle.
Now, to prove our question, we will use appolonius theorem which states that "the sum of the squares of any of the two sides of a triangle is equal to twice the square on half the third side including twice the square on the median that bisects the third side.
Applying this theorem to the image attached, we have the following;
|AB|² + |AC|² = 2[|AD|² + |BC/2|²]
|AB|² + |BC|² = 2[|BE|² + |AC/2|²]
|AC|² + |BC|² = 2[|CF|² + |AB/2|²]
Adding the 3 equations above gives us;
2|AB|² + 2|BC|² + 2|AC|² = 2|AD|² + |BC|²/2 + 2|BE|² + |AC|²/2 + 2|CF|² + |AB|²/2
Collecting like terms;
(2|AB|² - |AB|²/2) + (2|BC|² - |BC|²/2) + (2|AC|² - |AC|²/2) = 2|AD|² + 2|BE|² + 2|CF|²
Thus gives;
(3/2)[|AB|² + |BC|² + |AC|²] = 2[|AD|² + |BE|² + |CF|²]
Multiply both sides by 2 to give;
3[|AB|² + |BC|² + |AC|²] = 4[|AD|² + |BE|² + |CF|²]

I divided 9.60 by 12.
To find the answer, just divide the amount of donuts to the price.
9.60 / 12 = 0.80
So, each donut costs .80 cents.

The area of a rectangular parking lot is 4947 m2.
If the length of the parking lot is 97 m, what is its width?
Width of the parking lot:
The perimeter of a rectangular pool is 304 m.
If the width of the pool is 68 m, what is its length?
Length of the pool:
Answer:
1. width = 51 m
2. length = 84 m
Step-by-step explanation:
So remember, the area is (length * width).
It is given that the length is 97, and the area is 4947.
So plug this into a formula:
length * width = area
97 * width = 4947
Solve using inverse operations;
97 * width = 4947
/97 /97
width = 51m
The perimeter of a rectangle can be found by doing, (2 * (length + width)).
The width is given, it is 68m. The perimeter is also given, 304m. So just form an equation using this information:
2 * ( length + width) = perimeter
2 * (length + 68 ) = 304
Distribute;
2 * ( length + 68) = 304
2 length + 136 = 304
Inverse operations;
2length + 136 = 304
-136 -136
2length = 168
/2 /2
length = 84m
Answer:
The answer for number 1 is width = 51 m
The answer for number 2 is length = 84 m
