Answer:
113.04
Step-by-step explanation:
Use the formula A=[tex]\pi[/tex][tex]r^{2}[/tex]
A= [tex]\pi (6^2 )[/tex]
6*6 =36
multiply 3.14 by 36
36*3.14=113.04
Christy spent 25 of her money on a shirt. She has $21.75 left. How much did she spend on the shirt?
A. $8.70
B. $7.25
C. $14.50
D. $29
Christ spent a total amount of $ 14.50 on the shirt.
Finding the amount spent on the shirt
Here we use the linear equation concept to solve the problem.
Since we do not know the amount that Christ has assume that with a variable and form a linear equation using the data given.
Now solve the resultant equation for the value of the variable and find the amount spent by Christ on the shirt as given below
Here we have
Christy spent 2/5 of her money on a shirt.
She has $21.75 left
Let 'x' be the amount that Christy has
From the data,
Christy spent 2/5 of her money on a shirt.
Amount spent by Christy = 2/5 of x = 2x/5
Remaining amount = x - 2x/5
From the data,
Chrisy is left with $ 21.75
=> x - 2x/5 = 21.75
=> 3x/5 = 21.75
=> 3x = 108.75
=> x = 36.25
Amount the that she spent 2x/5 = 2 (36.25)/5 = 14.50
Therefore,
Christ spent a total amount of $ 14.50 on the shirt.

What is the equation of a circle centered at the origin with radius 15 ?
_________________________ 6Harry is planning a holiday for 4 people for 7 days. Here are the costs for the holiday for each person. Travel£150 Hotel£50 for each day Spending money£250 Work out the total cost of the holiday for 4 people for 7 days.
Answer: $3,000
Step-by-step explanation:
The cost for a single person is:
Travel £150
Hotel £50 for each day
Spending money £250
Hotel is the only one that changes per the number of days so the total cost for a single person for 7 days is:
= 150 + (50 * 7) + 250
= 150 + 350 + 250
= $750
There are 4 people so the total cost will be:
= 750 * 4 people
= $3,000
How is the ratio of crushed tomatoes to tomato paste different from the ratio of tomato paste to crushed tomatoes?
Answer and explanation:
The ratio 1:2 is different from the ratio 2:1. The ratio 1:2(one to two) means a comparison of two sizes; the ratio of one part of that thing to the ratio of two parts of that thing. Likewise, the ratio 2:1 is the comparison of two parts of a thing to the ratio of one part of the thing. For the ratio 2:1, we could say for example that for every two crushed tomatoes there is one tomato paste.
Which is the graph of y= -x-3?
Answer:
Graph a
Step-by-step explanation:
Answer:
the answer is A
Step-by-step explanation:
to start, I would use the slope intercept, in this case -3 which lets you know the slope meets the y axis at (0,-3) since you have that point, you count with the slope.
now slope is rise over run, therefore, it would be y over x and since the y in this case is 3, you'd go up three from your point. since x is 4, you'd go right four units from where you are. since A is the only graph that follows that, A would be correct.
What is the slope of y = -4?
Answer:
0
Step-by-step explanation:
The line is horizontal.
Explanation:
Think of y = -4 as y = 0x+(-4)
We see that the equation matches the form y = mx+b
m = 0 = slope
b = -4 = y intercept
Side note: this equation graphs out a horizontal line. All horizontal lines have a slope of 0.
One angle of a right triangle measures 34°. What is the measure of the other acute angle?
Answer:
Step-by-step explanation: one has to be 90 degrees, so 34 plus 90. The angles of a triangle always add up to 180 so, subtract the answer of 34 plus 90 from 80 and you should get the answer.

Answer: area mean multiply
Step-by-step explanation:
Answer:
76 feet (Just put 76 in the answer box)
Step-by-step explanation:
Knowing the perimeter of a rectangle is 2l + 2w, multiply 2 by 3.5. Then multiply 2 by 4.5, and add them together.
2(3.5) + 2(4.5)
The two products would be 7 and 9 respectively.
7 + 9 = 16 feet of fencing for 1 rabbit pen.
We have 2 pens, so multiply 16 by 2.
The rabbit pens need 32 feet of fencing.
(Alternatively you could have done 2(2(3.5 + 4.5)).
2(2(8))
2(16)
32 ft of fencing (rabbit pens))
Now, add 12 and 10. Then multiply that by 2.
2(12 + 10)
2(22)
The garden needs 44 feet of fencing.
Now add 32 and 44 to get the total amount of fencing needed.
32 + 44
The rabbit pens and the garden need 76 feet of fencing. (Just put 76 in the answer box as the unit (feet) is already given.)

Cuatro amigos van al cine dos veces al mes y siempre comen un paquete de palomitas de maiz cada uno si no comia palomitas de maiz los cuatro amigos podrian ir al cine tres veces al mes sabiendo que cada paquete de palomitas de maiz cuesta $28 cual es el precio de cada entrada al cine
Answer:
El precio de la entrada al cine es de $56
Step-by-step explanation:
Cada uno de los 4 amigos las 2 veces por semana consumen un paquete de palomitas que cuesta: $28 ; entonces debemos multiplicar el costo de las palomitas por las dos veces que las consumen para saber el costo total de las palomitas:
28 x 2 =$56
El ejercicio nos dice que al no comer esas dos veces palomitas pueden ingresar a cine una tercera vez por semana ,lo que significa que al no pagar los $56 en palomitas podrán pagar una tercera entrada,lo que quiere decir que la entrada a cine es de $56.
Entonces podemos hacer la siguiente relación matemática: Precio total de las palomitas dos veces por semana = Precio de la entrada a cine.

What are the values of a and b, and what is an equation for the line?
Answer:
a = 1, b = 6
Step-by-step explanation:
slope of line = (5-2) / (12-3) = 3/9 = 1/3
(3-2) / (b-3) = 1/3
b-3 = 3 b = 6
(2-a) / (3-0) = 1/3
2-a = 1 a = 1

Answer:
(b) 7720 mm² of paper
Step-by-step explanation:
The central horizontal rectangle of the net is 80 mm high and ...
40 + 5.5 + 40 + 5.5 = 91
mm long. Its area 9 is ...
(80 mm)(91 mm) = 7280 mm²
__
The two pieces of the net not accounted for above are the "flaps" above and below the central rectangle. Each of those two has an area of 40 mm by 5.5 mm, so their total area is ...
2(40 mm)(5.5 mm) = 440 mm²
Then the area of paper needed for the wrapper is ...
total area = 7280 mm² + 440 mm²
total area = 7720 mm²

The formula for the area of a trapezoid is A = 12(a + b)h. Rearrange the formula to solve for b.
Question 4 options:
b=2Aha
b=A−12h + a
b=2Ah− a
b=12Ah − a
Answer:
b = 2A/h - aStep-by-step explanation:
Formula for the area of a trapezoid:
A = 1/2(a + b)hSolving for b:
A = 1/2(a + b)h2A = (a + b)h2A/h = a + b b = 2A/h - a(Easy) What is the next term in the sequence: 2, -2/3, 2/9, -2/27
Answer:
[tex]\frac{2}{81}[/tex]
Step-by-step explanation:
There is a common ratio between consecutive terms in the sequence
r = [tex]\frac{-\frac{2}{3} }{2}[/tex] = [tex]\frac{\frac{2}{9} }{-\frac{2}{3} }[/tex] = [tex]\frac{-\frac{2}{27} }{\frac{2}{9} }[/tex] = - [tex]\frac{1}{3}[/tex]
To find a term in the sequence multiply the previous term by - [tex]\frac{1}{3}[/tex] , then
a₅ = - [tex]\frac{1}{3}[/tex] × a₄ = - [tex]\frac{1}{3}[/tex] × - [tex]\frac{2}{27}[/tex] = [tex]\frac{2}{81}[/tex]
