Answer:
14.00
Step-by-step explanation:
First, convert the 20% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 20%) by 100%.So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.
Second, you need to find out what 20% of your $70 meal cost is.This is always done by multiplying 0.20 by $70.00, or
0.20 x $70.00=$14.00.
So, the amount of tip you are going to leave is $14.00.
12. Suppose U= {1, 2, 3, 4, 5, 6, 7, 8} is the universal set and P= {1, 2, 3, 4]. What is P'? (1 point)
O {5, 6, 7, 8}
O {1, 2, 3, 4, 5, 6, 7, 8}
O {1, 2, 3, 4}
O cannot be determined
Answer:
o {5, 6, 7, 8}
Step-by-step explanation:
To find P'
P' = U - P
P' = {1, 2, 3, 4, 5, 6, 7, 8} - {1, 2, 3, 4}
P' = {5, 6, 7, 8} ANS.
Help please this makes no sense
Answer:
ST = 7.1 in
Step-by-step explanation:
we can use SOH-CAH-TOA because we've got a right triangle
side ST would be 'adjacent'
side TU would be the 'hypotenuse'
so we use Cosine because that's used when you're dealing with adjacent and hypotenuse:
cos 42° = ST/9.5
ST = cos 42° × 9.5
ST = 7.1

Round to the nearest tenth.
well, let's notice at the coordinates for A and B, A(-2 , 1) and B(1 , -1)
[tex]~~~~~~~~~~~~\textit{distance between 2 points} \\\\ A(\stackrel{x_1}{-2}~,~\stackrel{y_1}{1})\qquad B(\stackrel{x_2}{1}~,~\stackrel{y_2}{-1})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ AB=\sqrt{[1 - (-2)]^2 + [-1 - 1]^2}\implies AB=\sqrt{(1+2)^2+(-2)^2} \\\\\\ AB=\sqrt{9+4}\implies AB=\sqrt{13}\implies AB\approx 3.6[/tex]

Answer:
$28
Step-by-step explanation:
They said that they offered a 20% discount on all of its pizzas, so how we’re going to write the expression is
> 0.20p = 5.60
> 0.20p/0.20 = 5.60/0.20
> p = 28
So, in conclusion, the original price for the pizza, p, is 28 dollars.
Answer:
7.
Step-by-step explanation:
5.6 is 80% of 7
5.6 is a 80% decrease of 28
One cold day last week the ice cream store sold 1 milk shake and 3 ice cream cones for a total of $7.50. It warmed up a bit a few days later and they sold 3 milk shakes and 5 ice cream cones for a total of $17.50. Which system of equations can be used to calculate the cost of each item
Answer:
1s+3c=7.5
3s+5c=17.5
Step-by-step explanation:
You will use these two equations and solve for the shakes in the first one. S=3.75
C=1.25
LMNP is a rectangle. Find the value of x and the length of each diagonal. LN=13x-10 and MP=9x+9
Answer:
the diagonals of a rectangle are equal in
in length so. LN=MP
13x -10=9x+9
13x-9x=9+10
4x=19
x=19/4

Caty bought a new pair of shoes for $54. If the shoes had a discount of 15%, how much were the shoes with the discount?
Answer:
$45.9
Step-by-step explanation:
$54 × 0.15 = $8.1 <-- because it is a discount, we will subtract this amount
$54 − $8.1 = $45.9

If q/18 = 5 what does q = to
Answer:
Q= 90
Step-by-step explanation:
To do this problem you need to get q by itself and to do that you would move the 18 over
When you move the 18 over however you need to multiply and you will get 90
When ever you want to get a variable by itself always remember to switch the sign so if it was positive then switch it to negative and vice versa. It will also apply to multiplication and division just like this one
Answer:
q=90
Step-by-step explanation:
first you're going to multiply both sides of the equation by 18
[tex]18[/tex]×[tex]\frac{q}{18}[/tex][tex]=18[/tex]×[tex]5[/tex]
next you're going to reduce the numbers with the greatest common factor 18
equation now: q=18×5
lastly you're going to multiply the numbers
18×5=90
so q=90

which measurement is the best estimate for the height of a kitchen counter?
1. 0.9 mm
2. 0.9 cm
3. 0.9 km
4. 0.9 m
If you can help me I love you
Answer:
Building height = 48 feet.
Process :-
the man and the building are casting shadow at same time so the they both are getting sunlight at the same angle.
Let's suppose height of the building as x.
we get,
x/72 = 6/9
or, 9x = 432
so, x = 48
Your friend has a bag of 20 marbles. Seven
are blue, four are red, two are green, and
three are yellow. If the rest are white, what
percent of the marbles are white?
Answer:
20%
Step-by-step explanation:
given the info, let's add up all of the marbles we have so far
7 + 4 + 2 + 3 = 16 marbles
the rest are white and the total number of marbles in the bag are 20
16 marbles + white marbles = 20 marbles
there must be 4 white marbles
putting this in a fraction is 4/20
to put in percentage multiply by 100
4/20 × 100 = 20%

two numbers less than 8 that
have 3 as their GCF
Answer:
3 and 6
Step-by-step explanation:
GCF's or greatest common factors of numbers 1 to 8
1 : 1
2 : 1, 2
3: 1 , 3
4 : 1, 2, 4
5 : 1, 5
6 : 1, 2, 3, 6
7 : 1, 7
8 : 1, 2, 4, 8
3 and 6 have 3 as their GCF
Answer:
2#8?+76++887
Step-by-step explanation:
GCF < 2 : 2 and 7, 12 and 13GCF = 2 : 2 and 6GCF = 3 : 3 and 6GCF > 3 : 4 and 12, 6 and 18Step-by-step explanation:The greatest common Factor (GCF) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.(a) 2 and 7: Both 2 and 7 are prime numbers, therefore the GCF of 2 and 7 is 1 which is less than 2.(b) 2 and 6: Both 2 and 6 are even numbers, therefore the GCF of 2 and 6 is 2.(c) 4 and 12: Both 4 and 12 are even numbers and multiple of 4, therefore the GCF of 4 and 12 is 4 which is greater than 3.(d) 12 and 13: 13 is a prime number, therefore the GCF of 12 and 13 is 1 which is less than 2.(e) 6 and 18: Both 6 and 18 are even numbers and multiple of 6, therefore the GCF of 6 and 18 is 6 which is greater than 2 and greater than 3.(f) 3 and 6: Both are multiple of 3, therefore the GCF of 3 and 6 is 3.
how do you graph 3x= -135
Answer:
see below
Step-by-step explanation:
first isolate x
3x = -135
divide both sides by 3
3x/3 = x
-135/3 = -45
x = -45
we can then graph it
x is gonna be equal to -45
so draw a point on the x intercept at -45 and draw a vertical line going up and down
it should look like the graph shown below
Answer:
You would graph a vertical line at (-49, 0)
Step-by-step explanation:
3x = -135
Divide both sides by 3
x = -45
You would graph a vertical line at (-49, 0)
P.S., that system acts strange sometimes so be sure to only do one square up once you press -45. :)
