Answer:
The correct answer is 135
Step-by-step explanation:
This is because her rate is 15 flowers per 5 minutes, and there is 45 minutes. Therefore, 5 minutes occurs 9 times in 45 minutes and fifteen flowers times 9 groups of five minutes is 135.
Answer:
135
Step-by-step explanation:
Because if it took 5 mins to plant 15 flowers, you can count how many 5's there are in 45 which there is 9 fives In 45 so, 15x9=135 and therefore she planted 135 flowers in 45 minutes :)
The average of 5 numbers is 33. If the average of first 2 numbers is 35 and that of last 2 is 31, then find the 3rd number.
a. 34
b. 35
c. 33
d. 32
Answer:
the answer is c

What is the LCD of 8/21 and 2/7?
Answer:
21
Step-by-step explanation:
7 can go into 21
Answer:
21
Step-by-step explanation:
Equivalent Fractions with the LCD
8/21 = 8/21
2/7 = 6/21
Solution:
Rewriting input as fractions if necessary:
8/21, 2/7
For the denominators (21, 7) the least common multiple (LCM) is 21.
LCM(21, 7)
Therefore, the least common denominator (LCD) is 21.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
8/21 = 8/21 × 1/1 = 8/21
2/7 = 2/7 × 3/3 = 6/21
Is this answer correct?
Answer:
yes
Step-by-step explanation:
Find the next two numbers in a pattern?
7, - 28,112, - 448 __, __, . . .
Answer:
1,792 -7168
the pattern is to multiply by -4
Step-by-step explanation:
7 · -4 = -28
-28 · -4 = 112
112 · -4 = -448
-448 · -4 = 1,792
1,792 · -4 = -7168

Use the distributive property of multiplication to find 8×22.
Hint: 22=2+20.
Answer: 8(20)+8(2)=178
Step-by-step explanation: (a)(b+c)=ab+ac, so 8(20+2)=8(20)+8(2)=178

-Why is Democritus important with regard to atomic theory?
-Dalton’s atomic theory was the first:
-What subatomic particle did JJ Thomson discover?
-In 1913, Neils Bohr proposed a new atomic model known as the _________ model, which is patterned after the solar system.
- List the 4 principles of Bohr’s model:
a.
b.
c.
- In 1926, Erwin Erwin Schrödinger used mathematical equations to describe the likelihood of finding an ________ in a certain position. This atomic model is known as the _________________________ model of the atom.
-In 1932, James Chadwick discovered the ____________.
-Since 1932, the atomic theory has been further enhanced by the concepts that protons and neutrons are made of even smaller units called _________
-Everything in the universe (except energy) is made up of ______________________ .
-Therefore everything in the universe is made up of ___________________.
-An atom itself is made up of three tiny kinds of particles called subatomic particles: ___________,
________________ and __________________ .
The protons and the neutrons make up the ________________ called the nucleus.
The _____________________ fly around above the nucleus in a small cloud.
The electrons carry a ________________ charge and the protons carry a ___________________charge.
In a normal (neutral) atom the number of protons _____________________ the number of electrons.
Answer:
-Why is Democritus important with regard to atomic theory? Democritus developed his atomic philosophy as a middle ground between two opposing Greek theories about reality and the illusion of change. He argued that matter was subdivided into indivisible and immutable particles that created the appearance of change when they joined and separated from others.
-Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.
-What subatomic particle did JJ Thomson discover? He discovered the electron in 1897.
-In 1913, Neils Bohr proposed a new atomic model known as the Bohr's model, which is patterned after the solar system.
- List the principles of Bohr's model:
a. An electron moves around the nucleus in a circular orbit.
b. An electron's angular momentum in the orbit is quantisized.
c. The change in an electron's energy as it makes a quantum jump from one orbit to another is always accompanied by the emission or absorption of a photon.
- In 1926, Erwin Schrödinger used mathematical equations to describe the likelihood of finding an electron in a certain position. This model is known as the Rutherford Model of an atom.
-In 1932, James Chadwick discovered the neutron.
-Since 1932, the atomic theory has been further enhanced by the concepts that protons and neutrons are made of even smaller units called quarks. The quarks themselves are in turn made of vibrating strings of energy.
-Everything in the universe (except energy) is made up of matter.
-Therefore everything in the universe is made up of atoms.
-An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons and electrons.
The protons and the neutrons make up the centre called the nucleus.
The electrons fly around above the nucleus in a small cloud.
The electrons carry a negative charge and the protons carry a positive charge.
In a normal (neutral) atom the number of protons is the same number of electrons.

17 is 50% of what number?
Answer: 34
Step-by-step explanation:
therefore, the answer to "17 is 50 percent of what number?" is 34, and you can also derive that 50 percent of 34 equals 17
Answer:
34
Step-by-step explanation:
This is a fairly simple problem. If 17 is 50% of something, that means it's half of something. That means to multiply 17 times 2, and you get 34.

The value of d in the given expression is 2/5.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
We are given an expression as
3/2 = 5d - 1/2
we need to solve for d;
3/2 = 5d - 1/2
5d = 3/2 + 1/2
5d = 4/2
5d = 2
d = 2/5
Hence, the value of d in the given expression is 2/5.
