Marcus has to write a 4 1/2 page essay for his English class.he has only written 1 1/6 pages. how many pages does he have left to write?
Answer:
3 2/6
Step-by-step explanation:
total pages to be written
add 4 to 1/2 using common denominators
4 1/2 = 8/2 + 1/2
= 9/2 or 27/6
pages Marcus wrote
add 1 to 1/6 using common denominators
1 1/6 = 6/6 + 1/6
= 7/6
pages left
27/6 - 7/6 = 20/6 or 3 2/6
The discriminant if a quadratic equation is negative. One solution is 4 + 7i. What is the other solution? *
7 - 4i
4 - 7i
- 4 + 7i
7 + 4i
==========================================================
Explanation:
When you have a quadratic in the form ax^2 + bx + c = 0, where a,b,c are real numbers, then a negative discriminant leads to having a pair of complex roots. The roots come in conjugate pairs meaning that p+qi is one root while p-qi is the other root. The p,q are real numbers.
In the case of 4+7i being one root, we have p = 4 and q = 7, since it matches with p+qi. The other root must be 4-7i since it matches with p-qi.
In short, we flip the plus to a minus when going from 4+7i to 4-7i. All of this applies when we have a,b,c as real numbers.
If we allowed a,b,c to be complex numbers, then the roots may not necessarily come in conjugate pairs.

A pyramid has a square base of length 8cm and a total surface area of 144cm². Find the volume of the pyramid. (Please use Pythagoras' Theorem thank you)
Answer:
[tex] \displaystyle V_{ \text{pyramid}}= 64 \: {cm}^{3} [/tex]
Step-by-step explanation:
we are given surface area and the length of the square base
we want to figure out the Volume
to do so
we need to figure out slant length first
recall the formula of surface area
[tex]\displaystyle A_{\text{surface}}=B+\dfrac{1}{2}\times P \times s[/tex]
where B stands for Base area
and P for Base Parimeter
so
[tex] \sf\displaystyle \: 144=(8 \times 8)+\dfrac{1}{2}\times (8 \times 4) \times s[/tex]
now we need our algebraic skills to figure out s
simplify parentheses:
[tex] \sf\displaystyle \: 64+\dfrac{1}{2}\times32\times s = 144[/tex]
reduce fraction:
[tex] \sf\displaystyle \: 64+\dfrac{1}{ \cancel{ \: 2}}\times \cancel{32} \: ^{16} \times s = 144 \\ 64 + 16 \times s = 144[/tex]
simplify multiplication:
[tex] \displaystyle \: 16s + 64 = 144[/tex]
cancel 64 from both sides;
[tex] \displaystyle \: 16s = 80[/tex]
divide both sides by 16:
[tex] \displaystyle \: \therefore \: s = 5[/tex]
now we'll use Pythagoras theorem to figure out height
according to the theorem
[tex] \displaystyle \: {h}^{2} + (\frac{l}{2} {)}^{2} = {s}^{2} [/tex]
substitute the value of l and s:
[tex] \displaystyle \: {h}^{2} + (\frac{8}{2} {)}^{2} = {5}^{2} [/tex]
simplify parentheses:
[tex] \displaystyle \: {h}^{2} + (4 {)}^{2} = {5}^{2} [/tex]
simplify squares:
[tex] \displaystyle \: {h}^{2} + 16 = 25[/tex]
cancel 16 from both sides:
[tex] \displaystyle \: {h}^{2} = 9[/tex]
square root both sides:
[tex] \displaystyle \: \therefore \: {h}^{} = 3[/tex]
recall the formula of a square pyramid
[tex]\displaystyle V_{pyramid}=\dfrac{1}{3}\times A\times h[/tex]
where A stands for Base area (l²)
substitute the value of h and l:
[tex] \sf\displaystyle V_{ \text{pyramid}}=\dfrac{1}{3}\times \{8 \times 8 \}\times 3[/tex]
simplify multiplication:
[tex] \sf\displaystyle V_{ \text{pyramid}}=\dfrac{1}{3}\times 64\times 3[/tex]
reduce fraction:
[tex] \sf\displaystyle V_{ \text{pyramid}}=\dfrac{1}{ \cancel{ 3 \: }}\times 64\times \cancel{ \: 3}[/tex]
hence,
[tex] \sf\displaystyle V_{ \text{pyramid}}= 64 \: {cm}^{3} [/tex]

Answer:
Slope= 2 ; y intercept= 4
Step-by-step explanation:
Slope: (y2 - y1)/(x2-x1) where x and y indicate the coordinates of two points
Slope = (4-0)/(0-(-2) = 4/2 = 2
y intercept is where the line intercepts the y axis: it happens in (0;4)
Answer:
y intercept is 4 and slope is 2

A right prism has a volume of 65 cubic inches. The prism is enlarged so its height is increased by a factor of 20, but the other dimensions do not change. What is the new volume? A.1000 in .3 B.1300 in .3 C.1200 in. 3 D. 1100 in.3
Answer:
Volume of a right prism = 65 cubic inches
Its height is increased by a factor of 20.
To find:
The new volume of the prism if the other dimensions do not change.
Solution:
The volume of a prism is:
[tex]Volume=Bh[/tex]
Where, B is the base area and h is the height.
A right prism has a volume of 65 cubic inches.
[tex]65=Bh[/tex]
The height of prism is increased by a factor of 20. So, the new volume is:
[tex]Volume=B(20h)[/tex]
[tex]Volume=20(Bh)[/tex]
[tex]Volume=20(65)[/tex]
[tex]Volume=1300[/tex]
The volume of the new prism is 1300 in³.
Therefore, the correct option is B.

If measured at the same moment, the length of a person's shadow varies directly with the height of the person. If a 3 foot child casts a 5 foot shadow, what is the length of the shadow of a 6 foot adult?
Answer:
10 ft
Step-by-step explanation:
let l be length of shadow and h the height of a person
Given l varies directly with h then the equation relating them is
l = kh ← k is the constant of variation
To find k use the condition h = 3, l = 5 , then
5 = 3k ( divide both sides by 3 )
[tex]\frac{5}{3}[/tex] = k
l = [tex]\frac{5}{3}[/tex] h ← equation of variation
When h = 6 , then
l = [tex]\frac{5}{3}[/tex] × 6 = 5 × 2 = 10 ft
Round the number 74.054 to the nearest tenth
Answer:
74.054 rounded to the nearest tenth is equivalent to 74.1
Step-by-step explanation:
Since you're rounding 74.054 to the nearest tenth, you need to focus on the hundredths place. If the number on the hundredths place is greater than or equal to 5, then you round up. If not, keep the number in the tenths place the same. In this case, 5 is in the hundredths place, which means you need to round the 0 in the tenths place up by 1. So 74.054 rounded to the nearest tenths is equivalent to 74.1.
Question 7: The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg. How
much more does Anne's cat weigh?
A) 28 kg
B) 2 kg
C) 8 kg
D) 9.3 kg
Answer: C
Step-by-step explanation: The ratio shows that Anne's cat is 2kg heavier, but Meg's cat weighs 20kg which is 4 times what the ratio shows the weight is, so the difference of the weight is also 4 times greater, which is 8kg!
The value of weight of Anne's cat will be 28 kg. Then the correct option is A.
What is the ratio?The utilization of two or more additional numbers that compares is known as the ratio.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg.
Let 'x' be the weight of Anne's cat. Then the equation is given as,
5 / 7 = 20 / x
Simplify the equation, then we have
5 / 7 = 20 / x
1 / 7 = 4 / x
x = 28 kg
The value of weight of Anne's cat will be 28 kg. Then the correct option is A.
