Answer:
$18.00
Step-by-step explanation:
Start by working out 10%, that's easy:
15 ÷ 10 = 1.5
That means a 10% tip would be $1.50, so a 20% tip would be twice that amount:
1.50 x 2 = 3
A 20% tip is $3.00, and added on to the original $15.00, the total is $18.00

Professor Turner wrote the expression below on the chalkboard for his team at the Research Center. He asked the scientists there to write an equivalent expression that eliminated the parentheses.
Answer:
12x + 18y + 6z + 4x - 4z
Step-by-step explanation:
Given the expression : 3(4x + 6y + 2z) + 4(x – z)
To eliminate the parenthesis ; we use the distributive property :
3(4x + 6y + 2z) + 4(x – z) becomes ;
3*4x + 3*6y + 3*2z + 4*x + 4*-z
12x + 18y + 6z + 4x - 4z
Hence,
12x + 4x + 18y + 6z - 4z
16x + 18y + 2z
A cupcake store manager believes that half of the cupcakes sold are vanilla and that the other half is equally divided between chocolate and funfetti. If the manager's belief is correct and 400 cupcakes are sold, how many would you expect to be funfetti
400 cupcakes in total
200 would be vanilla
so 100 would be chocolate and the remaining 100 should be funfetti

Wo
45°
S
X
R
A. 116°
B. 45°
C. 710
D. 26°
someonee helpp plss
Answer:
to find the WX you have to use this formula
m>S=TR-WX/2
45=116-WX/2
90=116-WX
WX=116-90
WX=26
the answer is D 26
Answer:
D
Step-by-step explanation:
The secant- secant angle WSX is half the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] (116 - WX)° = 45° ( multiply both sides by 2 to clear the fraction )
116 - WX = 90° ( subtract 116° from both sides )
- WX = - 26° ( multiply both sides by - 1 )
WX = 26° → D
Find the value of x.
Answer:
x = 4
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
(19x + 3)° is an exterior angle of the triangle, then
11x - 2 + 9x + 1 = 19x + 3
20x - 1 = 19x + 3 ( subtract 19x from both sides )
x - 1 = 3 ( add 1 to both sides )
x = 4
If f (2) = 60 – 5.
find x for f (x) = 13
Answer:
The required value of [tex]x[/tex] is [tex]\frac{3}{5}[/tex]
Step-by-step explanation:
Given,
f (2) = 60 – 5
= (30 X 2) - 5
∴ f (x) = [tex]30x-5[/tex]
Again,
f (x) = 13 [given]
[tex]30x-5=13\\or, 30x= 13+5\\or, 30x=18\\or, x=\frac{18}{30} \\\\or, x=\frac{3}{5} \\[/tex]
∴[tex]x=\frac{3}{5}[/tex]
Verification:
f (x) = [tex]30x-5[/tex]
∴ f ([tex]\frac{3}{5}[/tex]) = (30 X [tex]\frac{3}{5}[/tex]) - 5
= 18 - 5
= 13
∴ The required value of [tex]x[/tex] is [tex]\frac{3}{5}[/tex]

For which value of x is the row in the table of values incorrect? The function is the quadratic function y = 5x2.
A. x = 3
B. x = 2
C. x = 0
D. x = 5
Answer:
A. x = 3
Step-by-step explanation:
0 times 5 = 0
2 times 5 = 10
3 times 5 = 15 then its 75
5 times 5 = 25 then its 125
it never equals to 45 for 3
you have to do it to the power of 2 for 3 and 5
is .02 equivalent to .002?
Answer:
No
Step-by-step explanation:
0.002 has one extra zero making it smaller than 0.02
Answer:
Step-by-step explanation:
.02 is the same thing as [tex]\frac{2}{100}=\frac{1}{50}[/tex]
.002 is the same thing as [tex]\frac{2}{1000}=\frac{1}{500}[/tex]
so, no, they are not equivalent.

x^2 = 2 × ( 2 + 4 )
x^2 = 2 × 6
x^2 = 12
x = √12
x = √4 × 3
x = 2√3
Answer:
x = 4
Step-by-step explanation:
Assume the dimension 4 is a diameter, and x is a tangent to the circle.
Use the tangent/secant formula to find
x*x = 2*(2+4)
x^2 = 16
x = 4
What is the solution of y= 4x + 6 when y= 18?
Answer:
18 = 4(3)+6
12 + 6
Step-by-step explanation:
the answer is 18 = 4(3)+6
because y is 18
Answer:
x=3
Step-by-step explanation:
[tex]18 = 4x + 6[/tex]
subtract 6 on both sides
[tex]12 = 4x[/tex]
divide both sides by 4
[tex]3 = x[/tex]

Answer:
7/2 cups of milk.
Step-by-step explanation:
1 3/4=7/4
2(7/4)=14/4=7/2
Answer:
7/2 cups of milk.
Step-by-step explanation:
If you want double the pancakes You must double the amount of milk:
First change it into an improper fraction:
1 3/4=7/4
then multiply it by two and simplify:
2(7/4)=14/4=7/2

the height in feet above the ground of an arrow after it is shot can be modeled by y=-16r^2+63r+4.Can the arrow pass over a tree that is 68 feet tall? Explain.
Answer:
yes
Step-by-step explanation:
y=-16r^2+63r+4
maximum value of y :
y'=0
-32r +63=0
r= 63/32
y = -16(63/32)²+63(63/32)+4
= -4 + 124 + 4 = 124 ft
124 > 68
the Arrow can pass over the tree
Amy is baking her famous pies to sell at the Town Fall Festival. She uses 32 ¼ cups of flour for every 1 ½ batches of pie that she makes. How many cups of flour would Amy use for 7 batches of pie?
Answer:
150-1/2 (150.5) cups of flour
Step-by-step explanation:
We know there is a ratio of 32.25 / 1.5 (32-1/4 cups of flour for every 1 1/2 batches of pie that she makes). X is the unknown (as we are trying to solve for flour) so we can set up the problem as such:
32.25 = x
1.5 7
Now we cross multiply to solve:
1.5(x) = 7(32.25)
1.5x = 225.75 -- Simplify then divide both sides by x (to isolate the variable)
x = 150.5
Answer: She uses 32 ¼ cups of flour for every 1 ½ batches of pie
Let’s make it into whole numbers to start…
She uses 64 ½ cups of flour for every 3 batches of pie
She uses 129 cups of flour for every 6 batches of pie
She uses 129/6 cups of flour for every 1 batch of pie
She uses 7 x 129/6 cups of flour for every 7 batches of pie
= 150 ½ cups of flour

GI = 6, HI = 8, DT = 12, what is IE?
a.12
b.16
c.8
d.4
Answer:
Option D
Step-by-step explanation:
By the property of intersecting chords,
If two chords are intersecting at a point inside a circle, product of lengths of the line segments on each chord is equal.
DI × EI = HI × GI
12 × EI = 8 × 6
EI = [tex]\frac{48}{12}[/tex]
EI = 4
Therefore, Option D is the correct option.
If 4 daps = 7 yaps, and 5 yaps = 3 baps, how many daps equal 42 baps? **GIVING OUT BRAINLIEST**
Answer:
40 daps
Step-by-step explanation:
lets say daps is d, yaps are y and baps are b
4d = 7y, 5y=3b
First convert to y
4/7d = y
Now convert that to b
5(4d/7) = 3b
20d / 7 = 3b
20d / 21 = b
Plug it in:
42(20d/21)
40d
aka 40 daps
