The Duncan family went out for dinner. They ordered 2 meals at $7.25 each and 1
meal at $5.50. They also had 3 drinks at $1.80 each and one dessert at $4.85.
a) Write an expression to evaluate the total amount spent.
b) Evaluate the expression to find the total amount spent before tip.
Answer:
look below
Step-by-step explanation:
(7.25 * 2) + 5.50 + (3 * 1.80) + 4.85
Lets combine
(7.25 * 2) + (3 * 1.8) + 10.35
7.25 * 2 is 14.50
3 * 1.8 is 5.4
14.50 + 5.4 + 10.35
is $30.25 before tip
(Tip should be 6.05 minimum, 20% of 30.25 is 6.05)
An item is regularly priced at $49. Kira bought it on sale for 45% off the regular price. find how much Kira paid.
Answer:
$26.95Step-by-step explanation:
First, find out what 45% of $49 is:
[tex]\frac{45}{100}[/tex] × $49
= [tex]\frac{2,205}{100}[/tex]
= 22.05
Since the question mentions "45% off" we know that we need to subtract 22.05 from 49.
49 - 22.05 = 26.95
Therefore, Kira paid $26.95.
I hope this helps!

6x=4x+10y
6x=4x+10y

A game has two four-sides dice having the number 1, 6, 7, and 4 on their faces. Outcomes in the sample space are pairs such as (1,6) and (4,4).
d. what is the probability that the total showing is greater than 9?
I have the other ones solved but really need help on the last one.
The sample space is
{(1,6),(1,7),(1,4),(6,7),(6,4),(7,4)}Pairs having sum greater than 9 are
E=3So
[tex]\\ \rm\hookrightarrow P(E)=\dfrac{3}{6}=1/2[/tex]
Answer:
1/2
Step-by-step explanation:
A sample space is a collection or a set of possible outcomes of a random experiment.
I have created the sample space for these data and attached it. As you can see there are 16 possible outcomes.
To find the probability that the total showing is greater than 9, simply identify the number of values in the sample space that are greater than 9.
(I have highlighted these in yellow).
Therefore, P(X>9) = 8/16 = 1/2

The value of N from the equation is N = 39
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
( N - 31 ) / 4 = 2 be equation (1)
On simplifying the equation , we get
Multiply by 4 on both sides of the equation , we get
N - 31 = 8
Adding 31 on both sides of the equation , we get
N = 39
Therefore , the value of N is 39
Hence , the equation is N = 39

GIVING BRAINILEST! Find the perimeter of the figure to the nearest hundredth!
Answer:
90.27mm
Step-by-step explanation:
radius=16mm
diameter=16mm x 2
=32mm
total length=1/2 x pi x 32mm +20mm+20mm
= 90.27mm (nearest hundredth)
Answer:
90.27 mm (nearest hundredth)
Step-by-step explanation:
Circumference of a circle = [tex]2\pi r[/tex] (where r is the radius)
Therefore, the arc length = 1/2 x 2 x [tex]\pi[/tex] x 16 = 16[tex]\pi[/tex]
So total perimeter = 2 x 20 + 16[tex]\pi[/tex] = 90.27 mm (nearest hundredth)

Answer:
66
Step-by-step explanation:
Angle 2 and 4 are supplementary, so if angle 4 is 123, then 180-123=57.
So angle 2 is 57.
Then, if angle 2 and 3 are 57 and we know that all angles of a triangle have to add up to 180, then:
57+57+angle 1=180
114+ angle 1=180
angle 1= 66

Hello!
Here we have fractions with unlike denominators.
So, we need to find the common denominator (the LCM of both denominators).
LCM stands for Least Common Multiple.
So, what is the L.C.M. of 4 and 8?
It is 8.
So, 8 is the lowest common denominator.
Now, we multiplied the denominator of the first fraction by 2, so we multiply the numerator by 2:
[tex]\bf{\displaystyle\frac{3}{4} = \frac{6}{8}[/tex]
Now, add:
[tex]\bf{\displaystyle\frac{6}{8} +\frac{3}{8}[/tex]
[tex]\bf{\displaystyle\frac{9}{8}[/tex]
Final Answer:
[tex]\bf{\displaystyle\frac{9}{8}[/tex] (Improper fraction)
[tex]\bf{\displaystyle1\frac{1}{8}[/tex] (Mixed number)
I hope it helps you.
