Below is a piece of a local pizza place menu where Jacob works.
Large Cheese Pizza $14.85
Large Supreme Pizza $16.90
Cheese Sticks $5.99
Dessert Pizza $6.99
4. The largest order last Saturday was from a basketball team that ordered 5 large supreme pizzas, 5 large cheese pizzas, 5 orders of cheese sticks and 5 dessert pizzas. Jacob said the total was about $225. Is this reasonable? Justify your response using estimation. If the answer is not reasonable, identify the error and then calculate the correct solution.
Answers
Jacob's estimate of $225 for the basketball team's order is reasonable. Our calculations show a total estimated cost of $223.75, which is close to Jacob's estimate.
To determine if Jacob's estimated total of $225 for the basketball team's order is reasonable, we can perform a quick estimation.
First, let's list the items ordered:
5 large supreme pizzas at $16.90 each5 large cheese pizzas at $14.85 each5 orders of cheese sticks at $5.99 each5 dessert pizzas at $6.99 eachNext, we will estimate the total cost for each category:
5 large supreme pizzas: $16.90 x 5 = approximately $84.505 large cheese pizzas: $14.85 x 5 = approximately $74.255 cheese sticks: $5.99 x 5 = approximately $305 dessert pizzas: $6.99 x 5 = approximately $35Now, summing these estimates: $84.50 + $74.25 + $30 + $35 = $223.75
Thus, Jacob's estimate of about $225 is reasonable, as our estimation shows a total of $223.75, which is close to his figure.

A=Lw
A=91(68)
A=6,188 m
Next you have to find the area of the semi- circles.
A of circle= radius to the second power times pi
A=68x68
A= 4,624
Multiply the area of the semi- circles by 2 since there are two of them. That will give you 9,248 m. Add 9,248 with 6,188 and that will give you your final answer which is 15,436 m.
The diameter of a sphere is 8 centimeters. What is the volume of the sphere? Use 3.14 for pi. Enter your answer, as a decimal, in the box. Round only your final answer to the nearest tenth. cm³
Answers
We are given the diameter of the sphere, but recall that the diameter is twice the radius: [tex]d=2r[/tex]. So the radius is half of the diameter: [tex]r= \frac{1}{2}d[/tex].
Half of 8 cm is 4 cm.
We substitute this for r in the equation and we use 3.14 for π.
[tex]V= \frac{4}{3}(3.14)(4)^3= \frac{(4^4)(3.14)}{3}=267.9 \ cm^3 [/tex]
recall volume of sphere formula is
[tex] \frac{4}{3} \pi \times r {}^{3} [/tex]
we know the diameter so to get the radius we just divide the diameter by 2 to get the radius
[tex]r = 8 \div 2[/tex]
[tex]r = 4[/tex]
know we can plug it into the volume of a sphere formula and solve using 3.14 for pi
[tex]v = (4 \times 3.14 \times 4 {}^{3} ) \div 3[/tex]
simplify the parentheses and get
[tex]v = \frac{803.84}{3} [/tex]
FINAL ANSWER (rounding to nearest tenth)
[tex]v = 267.9 \: cm {}^{3} [/tex]

Every time Rudy purchases a pack of cards, he will immediately trade the card of the member of his brother???s favorite team to his brother for 3 cards of members of a different team. Which of these recursive formulas produces the sequence that represents the number of baseball cards that Rudy will have at the end of each day, starting today?
Answers
The 300 value is the starting amount of cards that Rudy has.
The 17 represents the number of cards that he is getting per day. It started at 15 because that is the amount in a pack of cards. However, he trades one to his brother and gets 3 in return.
15 - 1 + 3 = 17 extra cards per day

Indeed, the total surface area can be found adding the base surface plus the lateral surface. In order to find the lateral surface, you can use the formula:
LS = (slant height × perimeter) / 2
Therefore:
if your slant height is 28, your answer will be 4116cm²
if your slant height is 35, your answer will be 4704cm²
if your slant height is 348.5, your answer will be 31038cm²
if your slant height is 14, your answer will be 2940cm²

Which algebraic expression represents this phrase? the product of 86 and the depth of the river
Answers
86d
An algebraic expression is a mathematical phrase that contains numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide).
We have to form the algebraic expression for the phrase
" The product of 86 and the depth of the river"
Let the depth of the river be 'd'
Therefore, the algebraic expression = Product of '86' and 'd'
= [tex] 86 \times d [/tex]
= 86d.
Therefore, the algebraic expression for the given phrase is "86d".
The vertices of quadrilateral abcd are a(1, a - 3), b(10, a), c(9, a + 3) and d(0, a).prove that the quadrilateral is a rectangle.find the midpoints of the diagonals.the midpoint of ac is (5,1)the midpoint of bd is (5,1)find the lengths of the diagonals.
Answers
Answer with explanation:
The Vertices of quadrilateral A B CD, are A(1, a - 3), B(10, a), C(9, a + 3) and D(0, a).
Mid point of AC= (5,1)
Mid point of B D= (5,1)
Mid point formula of two points having coordinates , (a,b) and (c,d) is , if (x,y), then
[tex]x=\frac{a+b}{2},y=\frac{c+d}{2}[/tex]
[tex]So,\rightarrow \frac{a-3+a+3}{2}=1\\\\\rightarrow \frac{2a}{2}=1\\\\\rightarrow a=1[/tex]
So, the coordinates of vertices of quadrilateral A B CD, are A(1, -2), B(10, 1), C(9, 4) and D(0, 1).
Distance formula of two points having coordinates, (a,b) and (c,d) is,
[tex]=\sqrt{(a-c)^2+(b-d)^2}[/tex]
[tex]AB=\sqrt{(10-1)^2+(1+2)^2}=\sqrt{81+9}=\sqrt{90}=3\sqrt{10}\\\\BC=\sqrt{(10-9)^2+(1-4)^2}\\\\=\sqrt{1+9}\\\\=\sqrt{10}\\\\CD=\sqrt{(9-0)^2+(3-0)^2}=\sqrt{90}=3\sqrt{10}\\\\DA=\sqrt{(1-0)^2+(1+2)^2}=\sqrt{10}\\\\AC=\sqrt{(9-1)^2+(4+2)^2}=\sqrt{64+36}\\\\AC=\sqrt{100}\\\\AC=10\\\\BD=\sqrt{(10-0)^2+(1-1)^2}\\\\BD=10[/tex]
Opposite sides AB and CD are equal to 3√10 unit and , BC and AD are equal to √10 unit.
Also,length of Diagonals , AC=B D=10 unit.
∴ The Quadrilateral, AB CD is a Rectangle.
Angela spent $30.00 at a resturaunt. if she leaves a 15% tip, how much wll her total bill be
Answers
_____________________________________________________
Explanation:
_____________________________________________________
15% = 15/100 = 15 ÷ 100 = 0.15 .
$30 + {0.15 * $30} = $30 + ($4.50) = " $34.50 " .
_____________________________________________________
Note: "15% of $30 = (0.15 * $30) = $4.50 .
We add the "$4.50" tip to the $30.00 that is spent; to get: " $34.50 " .
_____________________________________________________
Final answer:
Angela's total restaurant bill, after adding a 15% tip to her $30.00 original charge, will be $34.50.
Explanation:
To find out how much Angela's total bill will be after leaving a 15% tip at a restaurant, you first need to calculate the tip amount and then add it to the original bill. You calculate the tip by converting the percentage to a decimal and then multiplying by the cost of the meal. In this case, 15% of $30.00 is found by multiplying $30.00 by 0.15 which gives you $4.50. After calculating the tip amount, add it to the original bill to get the total amount Angela will pay.
Tip: $30.00 * 0.15 = $4.50.
Total bill: $30.00 + $4.50 = $34.50.
Therefore, Angela's total bill, including the 15% tip, will be $34.50.

Emma likes to knit hats and mittens for friends and family. Last fall, she knitted 4 hats and 3 pairs of mittens, which took a total of 46 hours. This fall, she knitted 2 hats and 1 pair of mittens, which took a total of 18 hours. If each hat and each pair of mittens takes the same amount of time to knit, how long does it take Emma to knit a hat and a pair of mittens?
Answers
Final answer:
Emma takes 4 hours to knit a hat and 10 hours to knit a pair of mittens, which was determined by solving two linear equations based on the time she spent knitting during two different falls.
Explanation:
Emma likes to knit hats and mittens, and we need to find out how long it takes her to knit a hat and a pair of mittens individually. Given that last fall she knitted 4 hats and 3 pairs of mittens in 46 hours, and this fall she knitted 2 hats and 1 pair of mittens in 18 hours, we can set up two equations to solve for the time it takes to knit each item.
Let's define H as the number of hours it takes to knit one hat and M as the number of hours it takes to knit one pair of mittens. The equations based on the given information are:
4H + 3M = 46 (Last fall's knitting)
2H + 1M = 18 (This fall's knitting)
To solve these equations, multiply the second equation by 2 to align the hats:
2(2H + 1M) = 2(18)
4H + 2M = 36
Now subtract this equation from the first equation to find M:
4H + 3M - (4H + 2M) = 46 - 36
M = 10
Substituting M back into the second original equation:
2H + 1(10) = 18
2H = 8
H = 4
Emma takes 4 hours to knit a hat and 10 hours to knit a pair of mittens.
choose the most appropriate strategy and then use it to solve the quadratic equation.
