Answer:
10 pizzas
Step-by-step explanation:
Jaxson is throwing a pizza party. He has 1\tfrac{1}{4}1 4 1 pounds of cheese available and he needs \tfrac{1}{8} 8 1 pound of cheese to make each pizza. How many pizzas can he make?
We can interprete the above question as:
1/8 pounds of cheese = 1 pizza
1 1/4 pounds of cheese = x pizzas
Cross Multiply
1/8 × x = 1 1/4 × 1
x = 1 1/4 ÷ 1/8
x = 5/4 ÷ 1/8
x = 5/4 × 8/1
x = 10 pizzas
x = 10 pizzas

Answer:
[tex]\huge\boxed{(2,\ 3);\ (-1,\ 6)}[/tex]
Step-by-step explanation:
[tex]f(x)=x^2-2x+3\to y=x^2-2x+3\\f(x)=-x+5\to y=-x+5\\\\\left\{\begin{array}{ccc}y=x^2-2x+3&(1)\\y=-x+5&(2)\end{array}\right[/tex]
substitute (1) to (2):
[tex]x^2-2x+3=-x+5[/tex] add x to both sides
[tex]x^2-2x+x+3=-x+x+5[/tex]
[tex]x^2-x+3=5[/tex] subtract 5 from both sides
[tex]x^2-x+3-5=5-5[/tex]
[tex]x^2-x-2=0\\\\x^2+x-2x-2=0\\\\x(x+1)-2(x+1)=0\\\\(x+1)(x-2)=0\iff x+1=0\ \vee\ x-2=0\\\\\boxed{x=-1\ \vee\ x=2}[/tex]
substitute the values of x to (2):
[tex]x=-1\\\\y=-(-1)+5=1+5=6\\\\\huge\boxed{(-1,\ 6)}\\\\x=2\\\\y=-2+5=3\\\\\huge\boxed{(2,\ 3)}[/tex]
Point R is located at (1, 2) on a coordinate grid. Point S is located at (4, 5) on the same
coordinate grid. What is the distance from point R to point S, rounded to the nearest tenth?
A. 3.2 units
B. 4.6 units
C. 7.6 units
D.
10.0 units
Answer:
4.2 units
most likely answer choice B
Step-by-step explanation:
(1, 2) and (4, 5)
To find the distance between two points, we use the distance formula:
[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]
Let's plug in what we know.
[tex]d = \sqrt{(4 - 1)^2 + (5 - 2)^2 }[/tex]
Evaluate the parentheses.
[tex]d = \sqrt{(3)^2 + (3)^2 }[/tex]
Evaluate the exponents.
[tex]d = \sqrt{(9) + (9) }[/tex]
Add.
[tex]d=\sqrt{18}[/tex]
Evaluate the radical.
d = 4.24
Round to the nearest tenth.
d = 4.2 units
*note: The answer choice is 4.6. I'm not sure if that is a typo on someone's end, but the distance between these two points is exactly 4.24264068712 units.
Hope this helps!
Answer:
C. 7.6 units

The area of the trapezium above is 22 cm².
What is the value of x ?
Answer:
4cm
Step-by-step explanation:
Given area= 22cm²
Height =4cm
Parallel sides = xcm and 7cm
Area of trapezium = ½( sum of parallel sides) x height
22cm² = ½(xcm+7cm)×4cm
22cm²= ½ ( x+7)cm x 4cm
opening the bracket
22cm²= 4x+28/ 2
cross multiply
44cm²=4x+28
4x=44-28
4x=16
x=4cm

A drawer contains 2 Red Socks, 7 White Socks, and 9 blue sock Without looking, you draw out a sock and then draw out a second sock without returning the first sock. What is the probability that the first sock and the second sock are both red?
Answer:
1/153
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
probability that the first sock and the second sock are both red = (number of red socks /total number of socks) x (number of red socks /total number of socks)
At the first pick, the probability = 2/18
At the second pick because there is no replacement, there would be 1 red socks and 17 socks = 1/17
2/18 x 1/17 = 1/153
Roderick wants to draw a circle for which the numerical value of the circumference is greater than the value of the area. Which lengths could he use for the radius? Select three options. One-half 1 1.5 2 2 and one-half
Answer:
One-half
1
1.5
Step-by-step explanation:
Area of a circle = πr²
The circumference of a circle = 2πr
n = 3.14
r = radius
Where : = π = pi = 22/7
R = radius
when radius is 1/2
Area = π x (1/2)^2 = 0.25π
circumference = 2π (1/2) = 1
the circumference is greater than the value of the area
when radius is 1 1/2
Area = π x (1 1/2)^2 = 2.25π
circumference = 2π ( 1 1/2) = 3
the circumference is greater than the value of the area
when radius is 1
Area = π x (1 )^2 = 1π
circumference = 2π ( 1) = 2
the circumference is greater than the value of the area
when radius is 2
Area = π x (2 )^2 = 4π
circumference = 2π ( 2) = 4
circumference equals area

A, B, C

How DISGUISE WILL BE WRITTEN IN THE CODE
Answer:
what are you asking?
Step-by-step explanation:
HOW MANY DEGREES IS Angele a?
The little lines through the two sides of the triangle mean that those two sides are the same length.
When a triangle has two sides that are the same length the bottom two inside angles are also the same.
The bottom left angle is given as 68 degrees, so angle a would also be 68 degrees.
The answer is a = 68
What is the answer to this question?
Answer:
A-75 and B-25
Step-by-step explanation:
Firstly, divide the 200 students by the amount of sections (8) and that gives you 25 a section. Since year 7 has 3 sections and year 9 has 1, 3(25)=75 and 25(1)=25.
Answer:

Answer:
650 ft^2
Step-by-step explanation:
Without the gap, the area of the rectangle is 20ft x 35ft = 750 ft^2. The gap is a square having 10ft on the side so its area is 10ft x 10ft = 100 ft^2. Subtracting the area of the square gap from the rectangle gives you 650 ft^2.

Josh and Ethan have a total of 70 baseball cards between the two of them. Josh has sixteen more than twice the number of cards Ethan has. Write and solve an equation to find the number of baseball cards each has.
Answer:
j + e = 70
j = 2e + 16
e = 18
j = 52
Step-by-step explanation:
two equations can be derived from the question
j + e = 70 eqn 1
j = 2e + 16 eqn 2
j = josh card
e = ethan's card
rewrite equation 2
j -2e = 16 eqn 3
subtract equation 3 from 1
3e = 54
e = 18
substitute for e in equation 1
j = 70 - 18 = 52

In rectangle MNOP, MO = 4x - 10 and NP = 2x + 4.
What is the length of a diagonal?
Answer:
18
Step-by-step explanation:
From the rectangle, M O = NP
4x - 10 = 2x+4
4x-2x = 4 + 10
2x = 14
x = 14/2
x = 7
SInce MO and NP are the diagonal
Length of diagonal = 4x- 10
Length of diagonal = 4(7) - 10
Length of diagonal = 28 - 10
Length of diagonal = 18
hence the required length is 18

What is 78,400,000 expressed in scientific notation
The scientific notation of 78,400,000 will be 7.84 × 10⁷.
What is the law of indices?Index (indices) in Maths is the power or exponent which is raised to a number or a variable.
For example 5³ = 5²5 here we break 5³ into 5² and 5 so it is called the law of indices.
An algebraic expression is a quantity made up of symbols and processes + - / and multiplication Expressions utilizing indices are made simpler using the laws of indices.

what's the value of x
Answer:
the answer to this will be 15
Answer:
x=15
Step-by-step explanation:
The angles in a triangle always add up to 180°
3x+7x+2x=180
12x=180 (combine like terms)
[tex]\frac{12x}{12}[/tex]=[tex]\frac{180}{12}[/tex] (Divide both sides by 12)

Find the slope of the table below a.5,b.1,c.1/5, d.10
Answer:
Slope=2/10 or 0.2
Step-by-step explanation:
First, pick the numbers you want to use for slope. I will be using -10 as x1, 0 as x2, -1 and y1, and 1 for y2. The formula for slope is y2-y1/x2-x1.
Plug in these numbers: 1+1 (two negatives make a positive)/0+10(again, two negatives combine to make a positive)
This makes 2/10, which divided eaquals 0.2.
You can use either 2/10 or 0.2 as your answer, depending on what your teacher requires. Have a nice day and let me know if you have any questions!! :)
