charges an initial fee of $45 and $25 per month. Which a cheaper for 1
year?
How much cheaper?
Answer: Kim's gym
Step-by-step explanation:
$60 + $20 = $80$45 + $25 = $70If the solution to a linear system of equations is x=6 and y= 2 and you graphed the two equations, where would the two lines intersect? How do you know?
This is simply because the x coordinate is 6 and the y coordinate is 2.
The line x = 6 is a vertical line in which all points on it have an x coordinate of 6. It goes through 6 on the x axis.
The line y = 2 is horizontal where all points on it have a y coordinate of 2.
The vertical and horizontal lines intersect at (6,2)

Direction:find the volume of each solid figure below.
Step-by-step explanation:
9) volum = width× lenght × height
= 2×3×7 = 42 m³
10) = 7³ = 343 cm³
Answer:
Question 9: Volume = 42m
Question 10: Volume = 343cm
Step-by-step explanation:
Volume for a rectangular prism: V = length x height x width
Question 9:
Length = 7m
Width = 2m
Height = 3m
V = (7m) x (2m) x (3m)
V = 14m x 3m
Volume for a cube: V = a^3 → this is the formula since all sides are the same length
Question 10:
Length = 7cm
Width = 7cm
Height = 7cm
V = (7cm) x (7cm) x (7cm)
V = 49cm x 7cm
V = 343
OR
V = a^3 → (7)^3

3. Melissa and John get a combined monthly allowance of $300. Melissa's monthly allowance is
$20 more than half of John's monthly allowance. If x represents John's allowance, in dollars, which
equation is true?
A. x- (0.5x+20) = 300
B. x + (20+0.5x) = 300
C. x + 300=0.5x + 20
D. x + (0.5x20) = 300
Answer:
B. x-(0.5x+20)=300
Step-by-step explanation:
Because you add 20 to half of John's monthly allowance, and 0.5x is saying John's allowance divided by 2. Then you have Melissa's allowance, which then you add to John's allowance to get the total of $300 combined.
The equation that describes the situation would be; A. x-(0.5x+20)=300
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We are given that Melissa and John get a combined monthly allowance of $300. Melissa's monthly allowance is $20 more than half of John's monthly allowance.
When x represents John's allowance, in dollars
Since we add 20 to half of John's monthly allowance, 0.5x is saying John's allowance is divided by 2.
Now we have Melissa's allowance, which then adds to John's allowance to get a total of $300 combined.
The equation becomes as;

What is the sine ratio b2
keeping in mind that a rhombus is also a parallelogram, namely a quadrilateral with parallel opposite sides, however, a rhombus sides are all the same length, and its diagonals meet at right-angles, Check the picture below.
The ratio of the required trigonometric function sin b₂° as per the given measurement of the quadrilateral is equal to 39/ 50.
Let us consider quadrilateral ABCD be rhombus.
Using the properties of the rhombus,
All the sides are congruent to each other.
Here, AB = 5 cm
This implies,
AB = BC = CD = AD = 5 cm
And Intersection of the diagonal is point 'O'.
In rhombus diagonals bisects each other at 90 degrees.
Measure of angle BOC = 90 degrees.
Triangle BOC is right angled triangle.
OC = 3.9 cm
sin b₂° = opposite side / hypotenuse
= OC / BC
= 3.9 / 5
= 0.78
= 78 / 100
= 39 / 50
Therefore, the ratio of the function sin b₂° is equal to 39 / 50.

Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.
Lamar is comparing the cost of a fresh lobster dinner at two different restaurants. The first restaurant charges $35 for the meal, plus $4 per kilogram for the lobster he picks. At the second restaurant, Lamar would pay $3 per kilogram for the lobster, in addition to $44 for the meal. Lamar realizes that, in theory, dinner at both restaurants could cost the same amount if the lobster had a certain weight. How much would Lamar pay for his dinner? What is the weight?
Dinner would cost $__ at either restaurant if Lamar's lobster weighed __ kilograms.
Answer:
The weight : 9 pound
Lamar would pay for his dinner : $71
Step-by-step explanation:
Let x represent the weight of the lobster
the cost of the dinner at restaurant 1 is 4x + 35
the cost of the dinner at restaurant 2 is 3x + 44
Now ,we have to solve the equation :
4x + 35 = 3x + 44
-3x - 35 -3x - 35 -> trying to get all x terms on one side. other just #
4x - 3x = 44 - 35
⇔ 1x = 9
⇔ x = 9
In this case Lamar would pay the same amount for his dinner at any restaurant:
the price = 4×(9)+35 = 71
= 3×(9)+44 = 71.

What is the area of the composite figure?
Will mark brainlyest!!
Answer:
(a) 88 m²
Step-by-step explanation:
The area of a composite figure can be found by decomposing it into figures whose areas are easy to calculate. This figure can be decomposed any of several ways (as is often the case).
Drawing a vertical line down from the top-edge vertex, we can divide the figure into a trapezoid on the left and a rectangle on the right.
__
TrapezoidThe trapezoid will have (vertical) bases of 4 m and 6 m, and a height of (16-8) = 8 m. Its area is ...
A = 1/2(b1 +b2)h = 1/2(4 +6)(8) = 40 m²
RectangleThe rectangle on the right is 8 m wide and 6 m high, so its area is ...
A = LW = (8 m)(6 m) = 48 m²
TotalThe total area is ...
trapezoid area + rectangle area = 40 m² +48 m² = 88 m²
The area of the composite figure is 88 m².
Explain what the acronym PEMDAS means and how you use it when evaluating expressions.
What’s the answer to this problem?
Answer:
Step-by-step explanation:
LA (Lateral area) = P (perimeter of the base) x h (distance between bases)
LA = 3 x 2
LA = 6
SA (surface area) = LA (Lateral area) + (2 x B (Area of the base))
SA = 6 + (2 x 0.25)
SA = 6.5m²
Answer:
7
Step-by-step explanation:
if you imagine the shape in your head, there would be 3 rectangles and 2 triangles.
so if you want the surface area of the entire shape, you have to add the areas of each of these sides
the area of 1 triangle is (1*1)/2 = 0.5
the area of 1 rectangle is more complicated:
you would have to work out the rectangles height, which is the hypotenuse of the triangle. so you use Pythagoras, and you get 1 (if you don't know how to do this search up Pythagoras theorem)
so now you can get the area of the rectangle: 1*2 = 2
3 rectangles : 2*3 = 6
2 triangles : 0.5 * 2 = 1
6+1 = 7

Answer:
50 degrees
Step-by-step explanation:
If AB is congruent to BC, then angles BAC and BCA are congruent.
Angle DCB+ angle BCA= 180 degrees
180 degrees- 115 degrees= 65 degrees
It means that angles BCA and BAC (which are congruent) are equal 65 degrees.
Sum of angles i side a triangle is 180 degrees so:
180 degrees- 2*65 degrees= 180 degrees- 130 degrees= 50 degrees
The angle ABC is equal to 50 degrees.
. Mrs. Rojas deposited $8000 into an account paying 4% interest annually. After 8 months Mrs. Rojas withdrew the $6000 plus interest. Altogether, how much money did Mrs. Rojas withdraw? What fraction of a year's interest was earned? 760
well, keeping in mind that a year has 12 months, that means that 8 months is 8/12 of a year, when Mrs Rojas pull her money out.
[tex]~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$6000\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=years\to \frac{8}{12}\dotfill &\frac{2}{3} \end{cases} \\\\\\ A=6000[1+(0.04)(\frac{2}{3})]\implies A=6000\left( \frac{77}{75} \right)\implies A=6160[/tex]
well, she put in 6000 bucks, got back 160 extra, that's the interest earned in the 8 months.
what if she had left her money for 1 whole year, then
[tex]~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$6000\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=years\dotfill &1 \end{cases} \\\\\\ A=6000[1+(0.04)(1)]\implies A=6240[/tex]
so had she left it in for a year, she'd have gotten 6240, namely 240 in interest, well, what fraction of a year's interest was earned? or worded differently, what fraction is 160(8 months) of 240(1 year)?
[tex]\cfrac{\stackrel{\textit{for 8 months}}{160}}{\underset{\textit{for 12 months}}{240}}\implies \cfrac{2}{3}[/tex]
