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.
how do you simplify 24+3x=3x+2(3•4)
Answer:
all rational numbers
Step-by-step explanation:
24+3x=3x+2(3*4) shows that there can only be two possible answer, all integers or no solution. As you can see 2*3*4 is 24, making the answer all rational numbers.
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 ≤ 90Proved87.125 is it rational or irrational? Explain how.

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]

4/(1/3) = 4x3 = 12
there are 12 1/3 cup servings in 4 cups
Answer:
Hey there!
Contains 4 cups of trail mix
He wants 1/3 go cup servings
=> 4 ÷ 1/3
=> 4×3/1

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°.

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.

Given that ¹/x=²/y+¹/z. express y interms of x and z. if x=5 and z=10. find the value of y leaving your answer as a mixed fraction
Answer:
[tex]y=\dfrac{2xz}{(z-x)}[/tex]
Step-by-step explanation:
Given:
[tex]\dfrac{1}{x}=\dfrac{2}{y}+\dfrac{1}{z}[/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

Hello!
75,000 - 10% of 75,000
= 75,000 -(10*75,000)/100
= 75,000 -7,5 => 67,500
67,500 - 10% of 67,500
= 67,500- ( 10*67,500)/100
=67,500 - 6,75 = 60,750
60,750 -10% of 60,750
= 60,750-( 10*60,750)/100
= 60,750 - 6,075 => 54,675

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)
