Julio and his family ordered 6 pizzas for dinner. His parents ate 3/7 of one pizza, Julio's brothers ate 2 3/4 pizzas and his sisters ate 2 1/2 pizzas. How much pizza was left for Julio to eat?
approximately 0.3 or 3/10 pizza was left for Julio to eat.
mind you some numbers were rounded. if you want the exact number then it's 9/28 which is equal to 0.32.
hope this helps
After accounting for the amounts of pizza eaten by Julio's family (parents, brothers, and sisters), you find that there was approximately 0.36 pizzas left for Julio to eat.
Explanation:This question deals with some basic arithmetic and fractions. Start by counting how many pizzas Julio's family ate altogether. His parents ate 3/7 of one pizza, his brothers ate 2 3/4 pizzas, and his sisters ate 2 1/2 pizzas.
To add these amounts together, you might find it easiest to convert all the fractions to sevenths. The brothers ate 2 4/7 pizzas (as 4/7 is equivalent to 1/2) and the sisters ate 2 3.5/7 pizzas (as 3.5/7 is equivalent to 1/2). Add these to the 3/7 pizza the parents ate, you find the family ate a total of approximately 5.64 pizzas.
Since Julio's family ordered 6 pizzas in total, you then subtract the total amount eaten by the family from 6, which is approximately 0.36 pizzas. Therefore, Julio was left with 0.36 pizzas to eat.

At each point (x,y) on the curve the slope is 2x+3 the curve passes through the point (-3,0)
Answer:
The equation of the curve is y = x² + 3x
Step-by-step explanation:
I get your drift, but wish you had stated specifically that you wanted to find the equation of this curve.
Slope of tangent line to curve is dy/dx = 2x + 3.
Integrating that with respect to x yields y = x² + 3x + C.
The point (-3, 0) must satisfy this equation:
0 = (-3)² + 3(-3) + C, so C = 0.
The equation of the curve is y = x² + 3x
The equation of the curve where the slope at any point is 2x + 3 and it passes through the point (-3, 0) is y = x² + 3x.
The student's question involves finding the equation of a curve given that at each point (x, y) on the curve, the slope is 2x + 3, and the curve passes through the point (-3, 0). This is a problem that involves differential equations, as it asks us to find a function y(x) whose derivative with respect to x is given.
To find the equation of the curve, we integrate the slope function. Since the slope at any point is 2x + 3, we have:
∂y/∂x = 2x + 3
Integrating both sides with respect to x gives:
y = x² + 3x + C
To find the constant of integration C, we use the fact that the curve passes through (-3, 0). Substituting these values into the equation gives:
0 = (-3)² + 3(-3) + C
0 = 9 - 9 + C
Thus, C = 0, and the equation of the curve is:
y = x² + 3x.

Write an equation in standard form for the circle shown.
Answer:
B
Step-by-step explanation:
The intercepted angle is given as "34x+4"
The arc is 196.
Any intercepted angle of an arc that falls in the opposite circumference, it will have a measure half that of the arc intercepted.
Hence,
34x+4 = (0.5)(196)
34x + 4 = 98
34x = 98 - 4
34x = 94

Number of payments made in a year=12
Number of payments made = 36
Monthly payment amount = $93.33
True annual interest rate?
The true annual interest rate for this loan is approximately 1.44 or 144%.
The Breakdown
To calculate the true annual interest rate, we can use the formula for calculating the interest rate on a loan:
True Annual Interest Rate = [(Monthly Payment Amount × Number of Payments) / Loan Amount - 1] × 12
Given the information provided:
Loan Amount = $3,000
Number of Payments = 36
Monthly Payment Amount = $93.33
Substituting these values into the formula:
True Annual Interest Rate = [(93.33 × 36) / 3000 - 1] × 12
Calculating this expression:
True Annual Interest Rate = [(3360 / 3000) - 1] × 12
True Annual Interest Rate = (1.12 - 1) × 12
True Annual Interest Rate = 0.12 × 12
True Annual Interest Rate = 1.44
Therefore, the true annual interest rate for this loan is 1.44 or 144%.
If the angle of elevation of the escalator is 10° 21’ 36° find th length of the escalator (picture provided)
Answer:
The length of the escalator ≈ 1088.8 ft ⇒ answer (b)
Step-by-step explanation:
* Lets explain the problem
- Consider the escalator and the vertical raise formed a right
angle triangle
- The length of the escalator is the hypotenuse
- The vertical rise is on leg of the right triangle
- The angle of elevation is the angle between the hypotenuse
and the horizontal
* Now lets solve the problem
∵ Angle of elevation = 10° 21' 36"
∵ Vertical distance = 195.8 feet
* The vertical is opposite to the angle of elevation
∴ sin angel of elevation= the vertical/the length of the escalator
∴ sin(10° 21' 36") = 195.8/the length of the escalator
- By using cross multiplication
∴ The length of the escalator = 195.8/sin(10° 21' 36") = 1088.8 feet
* The length of the escalator = 1088.8 ft
Classify each conic section and write its equations in standard form. Show work.
[tex]4x^2+2y^2-8x+16y-52=0[/tex]
Answer:
The conic is ellipse of equation (x - 1)²/22 + (y + 4)²/44 = 1
Step-by-step explanation:
* Lets revise how to identify the type of the conic
- Rewrite the equation in the general form,
Ax² + Bxy + Cy² + Dx + Ey + F = 0
- Identify the values of A and C from the general form.
- If A and C are nonzero, have the same sign, and are not equal
to each other, then the graph is an ellipse.
- If A and C are equal and nonzero and have the same sign, then
the graph is a circle
- If A and C are nonzero and have opposite signs, and are not equal
then the graph is a hyperbola.
- If either A or C is zero, then the graph is a parabola
* Now lets solve the problem
The equation is 4x² + 2y² - 8x + 16y - 52 = 0
∴ A = 4 and C = 2 ⇒ same sign and different values
∴ The equation is ellipse
* The standard form of the ellipse is
(x - h)²/a² + (y - k)²/b² = 1
- Lets try to make this form from the general form
- Group terms that contain the same variable, and move the
constant to the opposite side of the equation
∴ (4x² - 8x) + (2y² + 16y) = 52
- Factorize the coefficients of the squared terms
∴ 4(x² - 2x) + 2(y² + 8y) = 52
- Complete the square for x and y
# To make completing square
- Divide the coefficient of x (or y) by 2 and then square the answer
- Add and subtract this square number and form the bracket of
the completing the square
# 2 ÷ 2 = 1 ⇒ (1)² = 1 ⇒ add and subtract 1
∴ 4[(x² - 2x + 1) - 1] = 4(x² - 2x + 1) - 4
- Rewrite as perfect squares ⇒ 4(x -1)² - 4
# 8 ÷ 2 = 4 ⇒ (4)² = 16 ⇒ add and subtract 16
∴ 2[(y² + 8y + 16) - 16] = 2(y² + 8y + 16)² - 32
- Rewrite as perfect squares ⇒ 2(y + 4)² - 32
∴ 4(x - 1)² - 4 + 2(y + 4)² - 32 = 52
∴ 4(x - 1)² - 4 + 2(y + 4)² = 32 + 4 + 52
∴ 4(x - 1)² + 2(y + 4)² = 88 ⇒ divide all terms by 88
∴ (x - 1)²/22 + (y + 4)²/44 = 1

The wall also has a built-in shelving unit that occupies an area of (x2 + 5x + 6) square units of wall space. If the wall is to be covered with wallpaper, how much wallpaper will be required?
Answer:
the total available area = (3x^2 + 4x + 1) - (2x^2 + 8x + 8) = x^2 - 4x - 7
Step-by-step explanation:
The question seems to ask available area and not how much wallpaper is required. Let's calculate the area of the rectangular window. Area of a rectangle = Length * Breath Area = (x + 2) * (x + 1) = x^2 + 3x + 2 The wall also has a built- in shelving unit that occupies an area of (x^2 + 5x + 6). So total area occupied by the rectangular wall and shelf is (x^2 + 3x + 2) + (x^2 + 5x + 6) = 2x^2 + 8x + 8. If the wall is to be covered with wallpaper

A person invests $1,150 in an account that earns 5% annual interest compounded continuously. Find when the value of the investment reaches $2,000. If necessary round to the nearest tenth.
The investment will reach a value of $2,000 in approximately_____years.
Answer:
11.1 years
Step-by-step explanation:
The formula for interest compounding continuously is:
[tex]A(t)=Pe^{rt}[/tex]
Where A(t) is the amount after the compounding, P is the initial deposit, r is the interest rate in decimal form, and t is the time in years. Filling in what we have looks like this:
[tex]2000=1150e^{{.05t}[/tex]
We will simplify this first a bit by dividing 2000 by 1150 to get
[tex]1.739130435=e^{.05t}[/tex]
To get that t out the exponential position it is currently in we have to take the natural log of both sides. Since a natural log has a base of e, taking the natual log of e cancels both of them out. They "undo" each other, for lack of a better way to explain it. That leaves us with
ln(1.739130435)=.05t
Taking the natural log of that decimal on our calculator gives us
.5533852383=.05t
Now divide both sides by .05 to get t = 11.06770477 which rounds to 11.1 years.

[tex]h=24\ ft[/tex] ----> convert to inches
[tex]h=24*12=288\ in[/tex]
substitute the values
[tex]LA=2\pi (8)(288)[/tex]
[tex]LA=4,608\pi\ in^{2}[/tex]
Find the lateral area in square feet
we have
[tex]h=24\ ft[/tex]
[tex]r=8\ in[/tex] -----> convert to feet
[tex]r=8/12=(2/3)\ ft[/tex]
substitute the values
[tex]LA=2\pi (2/3)(24)[/tex]

What is m∠B?
Round the value to the nearest degree.
Answer:
46°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you ...
Cos = Adjacent/Hypotenuse
You are given the lengths of the hypotenuse of the triangle and the side adjacent to the angle you want to find. So, the cosine function describes the relationship:
cos(B) = AB/CB = (20 cm)/(29 cm)
B = arccos(20/29) ≈ 46.397°
B ≈ 46°
The student is looking for the value of an angle, m∠B, which requires solving an equation and rounding to the nearest integer. The provided information does not give a direct method or equation for calculating m∠B, thus an answer cannot be given confidently.
Explanation:The student is asking to calculate the value of an angle, denoted as m∠B, to the nearest degree. This is a mathematics problem likely involving geometry or trigonometry.
In the information provided, different equations and scenarios for calculating angles and magnitudes are given, but they seem to be disconnected, and the specific question regarding m∠B isn't directly addressed by the provided equations and examples.
Without a direct relationship or equation including m∠B, or a diagram to reference, it is not possible to confidently provide the value of m∠B. However, the excerpts suggest that if we had an equation and needed to find an angle such as m∠B, we would solve the equation and then round the result to the nearest integer, as angles are typically given in integers when degrees of freedom are considered.
