Answer:
2.99
Step-by-step explanation:
1.) 2 goes into 5 2 times. So the 2 goes on top of the division sign
2.) 2x2=4
3.) Move 4 below 5
4.) Subtract 5-4=1
5.) Bring down 9
6.) 2 Goes into 19 9 times
7.) 2x9=18
8.) 19-18=1
9.) Bring down the 7
10.) 2 Goes into 17 8 times
11.) 2x8= 16
12.) 17-16=1
13.) Add a zero onto the end, bring down that zero
14.) 2 goes into 10 5 times.
15.) Round answer to 2.99 because with money you only have two decimals
Answer:
12:25
Step-by-step explanation:
Número de alunos matriculados: 2.500
Número de alunos selecionados: 1.200
A proporção que representa o número total de alunos selecionados em relação ao número de alunos matriculados é dada como:
Número de alunos selecionados: Número de alunos matriculados
= 1200: 2500
= 12 : 25
Shortest to tallest: Plant A, Plant B, Plant C.
Given:
Plant A 1/3 inch tall
Plant B 3/4 inch tall
Plant C 5/6 inch tall
Order from shortest to tallest.
First we need to get the least common multiple of the three fractions.
Multiple of 3: 3, 6, 9, 12
Multiple of 4: 4, 8, 12, 16
Multiple of 6: 6, 12, 18
Their least common multiple is 12. We need to multiply each fraction by the number that will give the product of 12 to the denominator.
Plant A: 1/3 * 4/4 = 4/12
Plant B: 3/4 * 3/3 = 9/12
Plant C: 5/6 * 2/2 = 10/12
Since the denominator is common, we will use the numerator as basis in ordering the plants from shortest to tallest.
4 is less than 9 and 9 is less than 10.
so, Plant A is the shortest, Plant B is the medium height, and Plant C is the tallest.
Answer:
y = 90
Step-by-step explanation:
If y varies jointly as x and z, then;
y = kxz
If y = 18 when x = 2 and z = 3
18 = k(2)(3)
18 = 6k
k = 18/6
k = 3
To get y when x = 5 and z = 6
y = kxz
y = 3(5)(6)
y = 15*6
y = 90
Hence the value of y is 90
