Lena pays $8.96 for every 3 ounces of coffee. If she were to
graph the relationship between the number of ounces of
coffee and the total cost, what would be the meaning of the
slope of this graph?
Answer:
A: the cost per pund of coffee
Step-by-step explanation:
You need x and y- values. So one would be the pound (x) and the other would be the cost (y)
A kite flying in the air has an 11-ft line attached to it. Its line pulled taut and casts a 9 -ft shadow. Find the height of the kite. If necessary, round your answer to the nearest tenth.
Step-by-step explanation:
All we have to do is apply the Pythagorean theorem which states that a²+b²=c²
where c is the hypotenuse of the triangle or the side facing the 90° angle.
Moreover a & b are the other two sides of the triangle.
[tex]11 {}^{2} = {9}^{2} + h {}^{2} [/tex]
where h is the height from the ground
[tex]121 = 81 + {h}^{2} [/tex]
[tex]h {}^{2} = 121 - 81[/tex]
[tex]h {}^{2} = 40[/tex]
[tex]h = \sqrt{40} = 6.324[/tex]
Rounding to the nearest tenth,
[tex]h = 6.3[/tex]
factorise 3-x^2 can’t do it
Answer:
(√3 - x)(√3 + x)
Step-by-step explanation:
Use difference of two square formula:
a² - b² = (a - b)(a + b)
So a² = 3 ⇒ a = √3
and b² = x² ⇒ b = x
Therefore, 3 - x² = (√3 - x)(√3 + x)

Maddie has 18 flowers plants to put in her garden. she wants to plant them on 3 rows with an equal number on each row. how many rows will she plant
Answer:
6
Step-by-step explanation:
18 ÷ 3 = 6
3+3+3+3+3+3=18
Answer:
6 per row
Step-by-step explanation:
If Maddie has to spread out a total number of flowers (18) over a set number of sections (3) you would be able to solve this by dividing the total into the sections, which would look something like 18/3.

Enola has a toy car collection. She keeps some in a display case and the rest on the wall. 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case. What is the total number of toy cars in Enola's collection?
Give me brainliest if right: 106.95
The total number of toy cars in Enola's collection is 500 if 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
She keeps some in a display case and the rest on the wall. 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.
Let x be the total number of toy cars in Enola's collection:
69% of x = x - 155
0.69x = x - 155
0.31x = 155
x = 500
Thus, the total number of toy cars in Enola's collection is 500 if 155 of her toy cars are on the wall, and 69% of her toy cars are in the display case.

Prove that the difference between a two-digit number and the product of its digits will always be a 2 digit number.
Solution:
Let's take the greatest two-digit number as an example.
=> 99Proving...
99 - (9 x 9) = Two-digit number=> 99 - 81 = Two-digit number=> 18 = Two-digit numberSince the difference between the greatest two-digit number and the product of its digits is a two-digit number, the difference between the other two-digit numbers '10, 11, 12.... 97, 98' and the product of its digits will always be a two-digit number, as the product of its digit is less than the two-digit number.
Hence proved. ✔✔
Step-by-step explanation:
Let the two-digit number is [tex]xy[/tex]
This can be written as:
10x + y, where 1 ≤ x ≤ 9 and 0 ≤ y ≤ 9The difference between the number and product of its digits is:
d = 10x + y - xyRewrite this as below:
d = 10x - xy + y - 10 + 10 =
x(10 - y) - (10 - y) + 10 =
(x - 1)(10 - y) + 10
We see that:
0 ≤ x - 1 ≤ 8 according to the condition given above1 ≤ 10 - y ≤ 10 again according to the condition given aboveThe value of d is then:
0 + 10 ≤ d ≤ 8*10 + 1010 ≤ d ≤ 90ProvedDesperately need help

Answer:
p = 23
q = 18
Step-by-step explanation:
The four interior angles of a square are all 90° each
4p - 2 = 90
⇒ 4p = 92
⇒ p = 92 ÷ 4
⇒ p = 23
5q = 90
⇒ q = 90 ÷ 5
⇒ q = 18
Answer:
p=23; q=18.
Step-by-step explanation:
1) m∠(XWZ)=90, then 4p-2=90 and p=23°;
2) m∠(WZY)=90, then 5q=90 and q=18°.

Answer:
[tex]y=\dfrac{2xz}{(z-x)}[/tex]
Step-by-step explanation:
Given:
[tex]\dfrac{1}{x}=\dfrac{2}{y}+\dfrac{1}{z}[/tex]
[tex]\implies \dfrac{2}{y}=\dfrac{1}{x}-\dfrac{1}{z}[/tex]
[tex]\implies \dfrac{2}{y}=\dfrac{z-x}{xz}[/tex]
[tex]\implies 2xz=y(z-x)[/tex]
[tex]\implies y=\dfrac{2xz}{(z-x)}[/tex]
When x = 5 and z = 10:
[tex]\implies y=\dfrac{2(5)(10)}{(10-5)}[/tex]
[tex]\implies y=\dfrac{100}{5}[/tex]
[tex]\implies y=20[/tex]

Sofie claims to be a tasting expert. To test her abilities, someone bakes Sofie a cake using 3 of the following
ingredients:
Coffee
Nutmeg
Vanilla
Cinnamon
Sea salt
Ginger
Sofie's challenge is to identify which set of 3 ingredients was used in the cake. Suppose that Sofie is just
randomly guessing.
What is the probability that Sofie correctly identifies the set of 3 ingredients in the cake?
Summing all the ingredients to get the total sample size, we applied the formula for obtaining the probability which is
Pr(3) = 0.5
ProbabilityGiven Data
Sample Space

= 75,000 -(10*75,000)/100
= 75,000 -7,5 => 67,500
67,500 - 10% of 67,500

=67,500 - 6,75 = 60,750
60,750 -10% of 60,750
