The picture below shows Annie and her younger brother Tommy’s money.
They want to combine their money to buy something together. How much do they have in all?
Annie has 4 dollar bills, 11 dimes, and 4 pennies. Tommy has 3 times and 3 pennies.
Step-by-step explanation:
Annie: 4 dollars = $4 11 dimes = 11 x 0.10 = $1.1 ( since 1 dime = 0.10 dollars)
4 pennies =4 x 0.01= $0.04 ( since 1 penny = 0.01 dollars)
Tommy 3 dimes = 3 x 0.10 = $0.3 3 pennies = 3x 0.01 = $0.03
Adding the values: 4 +1.1+0.04+0.3+0.03 = $5.47
A trip to the science and sports centers costs $38 per person. This price includes a $9 movie ticket and the entrance fees for both the science and sports centers. The cost of the entrance fees for each center are equal.
How much did entry to each center cost?
Subtract the $9 from the total then divide by 2:
38-9 = 29
29/2 = 14.50
Answer: $14.50 each
Subtract the $9 from the total then divide by 2
38-9 = 29
29/2 = $14.50

Find the missing angle for the irregular polygon. show your work.
Answer:
Sum of the interior angles=900º
x=80º
∠A=110º
∠C=130º
∠E=125º
Step-by-step explanation:
The shape is a heptagon. Meaning, the sum of the interior angles is 180º(n-2) where n is the number of sides. So, 180º(7-2)=180º(5)=900º.
So, we can add up all the angles.
x+30º+140º+x+50º+115º+x+45º+140º+140º=900º
3x+660º=900º
3x=240º
x=80º
Then, we can substitute for ∠A, ∠C, and ∠E
∠A=80+30=110º
∠C=80+50=130º
∠E=80+45=125º

mary wants to make a milkshake by choosing 5 flavors of ice cream and putting a scoop of each in the blender. If mary has 32 flavors of ice.cream available to her, how many different kinds of milk shakes can she make?
Answer:
201,376
Step-by-step explanation:
This is a combination because order doesn't matter
32 C 5 = 201,376
The number of different kinds of milkshakes that she can make will be 201,376.
What are permutation and combination?A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.
Mary wants to make a milkshake by choosing 5 flavors of ice cream and putting a scoop of each in the blender. If mary has 32 flavors of ice cream available to her.
Then the number of the different kinds of milkshakes that she can make will be given by the combination formula.
Combination = ³²C₅
Combination = 32! / [(32 - 5)! x 5!]
Combination = 32 x 31 x 30 x 29 x 28 x 27! / (27! x 5 x 4 x 3 x 2 x 1)
Combination = 8 x 31 x 29 x 28
Combination = 201,376
The number of different kinds of milkshakes that she can make will be 201,376.

Answer:
E(-9, 2)
Step-by-step explanation:
The line of reflection is is the perpendicular bisector of the segment between the original point and its reflected image.
In the figure, the y-axis is halfway between points A and E, and is a vertical line perpendicular to the horizontal segment AE. Point E has the same y-coordinate as point A, but its x-coordinate has the opposite sign.
(x, y) ⇒ (-x, y) . . . . . . reflection across the y-axis
A(9, 2) ⇒ E(-9, 2) . . . . reflection of point A across the y-axis
You get point E when you reflect A across the y-axis.

Additional comment
When A is reflected across the line y=x, it becomes point B. When it is reflected across the origin, it becomes point C. Reflection across the x-axis maps point A to point D.
(x, y) ⇒ (y, x) . . . . reflection across y=x
(x, y) ⇒ (-x, -y) . . . reflection across the origin
(x, y) ⇒ (x, -y) . . . . reflection across the x-axis

19. Write three equivalent fractions to
describe the portion of the stained glass
window that is gold,
Need help with 19 please help thank you
Answer:
3/5 = 6/10 = 9/15
Step-by-step explanation:
The picture shows a stained glass window that has 5 panels. The panels are presumed to be equal in size. Each represents 1/5 of the area of the window.
Three of those panels are gold. (The other two are green.) So, the fraction of the window that is gold is ...
3 × 1/5 = 3/5
__
Multiplying numerator and denominator of a fraction by the same value gives an equivalent fraction. We can write two more equivalent fractions using 2 and 3 as multipliers:
3/5 = (3/5)(2/2) = 6/10
3/5 = (3/5)(3/3) = 9/15
Three equivalent fractions for the gold portion of the window are ...
3/5, 6/10, 9/15.

Yes, 9 will be the answer...
Step-by-step explanation:
3x-5 =4+2x
3x-2x = 4+5 (By transposing method)
x =9
Hope this is correct
Answer:
yeah it is ,
putting the value of x as 9
=> 3x – 5 = 4 + 2x
=> 3×9-5=4+2×9
=> 27-5 = 4+18
=> 22 = 22

Remi's family is spending the afternoon in Kingsville. They plan to see a movie
that is over 1 hour long and then explore the town. The movie will cost the family
$27, and parking costs $3 per hour.
How long will the family be able to spend in Kingsville if they don't have
any other expenses and want to spend less than $48?
PLS HELP ITS DUE TODAY!!
Answer:
max of 7 hours
Step-by-step explanation:
First, calculate the maximum amount they can spend on parking:
total budget - movie cost = parking budget
48 - 27 = 21
Therefore, they have a maximum of $21 to spend on parking.
We are told that parking costs $3 per hour. To calculate the number of hours they can park:
Parking budget ÷ cost of parking per hour = number of hrs parking
21 ÷ 3 = 7
Therefore, have enough money to purchase 7 hours of parking (in addition to spending $27 on the movie)
So they can spend a maximum of 7 hours in Kingsville
Answer:
Less than 7 hoursStep-by-step explanation:
Let's set up inequality based on the given, considering x the number of hours the family can spend.
27 + 3x < 48Solve for x:
3x < 48 - 273x < 21x < 7The family can spend less than 7 hours

What is the value of x?

Answer:
x = 16 (value of x)
x+4 = 16+4 = 20
Step-by-step explanation:
Hey there! This is a right-triangle because you can see a right-angle (square symbol) there.
Pythagoras Theorem can apply with any right triangles, stating that the sum of adjacent squared and opposite squared equal to hypotenuse squared.
We can express the words above to equation as [tex]\displaystyle \large{c^2=a^2+b^2}[/tex] where c = hypotenuse. For a and b can either be defined as adjacent or opposite.
Adjacent and Opposite are sides that form right angle and Hypotenuse is the longest side and it’s the side that is the opposite of right angle.
From the given attachment, we can conclude that x + 4 is our hypotenuse. Therefore, substitute c = x+4.
[tex]\displaystyle \large{(x+4)^2 = x^2+12^2}[/tex]
Using the perfect square formula - [tex]\displaystyle \large{(x+y)^2 = x^2+2xy+y^2}[/tex]
Therefore, [tex]\displaystyle \large{x^2+2(x)(4)+4^2=x^2+144 \to x^2+8x+16=x^2+144}[/tex]
Since the expressions are in quadratic, we will move x²+144 to subtract the left side using transportation property.
[tex]\displaystyle \large{x^2+8x+16-x^2-144=0}\\\displaystyle \large{8x-128=0}\\\displaystyle \large{8x=128}\\\displaystyle \large{\frac{8x}{8}=\frac{128}{8}}\\\displaystyle \large{x=16}\\[/tex]
Therefore, x = 16 and x+4 is 16+4 = 20.
If you have any questions regarding the Pythagoras Theorem, feel free to ask in comment!

The coordinates of points A, B, and C are (5, 4), (–2, 1), and (4, –4), respectively. Which point, B or C, is closer to point A?
Answer:
The distance between two points (x1,y1) and (x2,y2) = √((x1-x2)2+(y1-y2)2) Distance between A and B = √((5--2)2+(4-1)2) = √(72+32) = √(49+9) = √58 = 7.62 Distance between A and C = √(12+82) = √65 = 8.06 Point B is closer to A. Another method to solve this problem is to draw the points on a graph paper and measure distance with a ruler.
Answer:
B
Step-by-step explanation:
|AB|=[tex]\sqrt{(1-4)^{2}+(-2-5)^2 }=\sqrt{58}[/tex]
|AC|=[tex]\sqrt{(-4-4)^{2}+(4-5)^2 }=\sqrt{65}[/tex]
What is 4 over 15 plus negative 7 over 45
Answer:
If what I think youre saying is correct, then it should be 1/9
Step-by-step explanation:
4/15 + (-7/45)
Multiply both numerator and denominator of 4/15 by 3 so that the denominator becomes 45 to match the other fraction.
12/45 + (-7/45)
As the fraction on the right side is negative, it is taken away from the left fraction, hence:
(12 - 7)/45
Therefore, with simple subtraction,
5/45
Simplify to 1/9
