Answer:
18 : 9 is the same thing as 18/9.
So if we want 1 : n = 1/n
(18 / 18) / (9 / 18)
=> 1 / 0.5
=> 1 : 0.5
Therefore, n = 0.5 is the solution of the equation.
Thanks!!
Answer:
n = 0.5
Step-by-step explanation:
To answer this question, we must first figure out the ratio 18:9.
What is 18 compared to 9?
If you said that 18 is double the amount of 9, or that 9 is half of 18, you are correct.
Using this logic, we then need to make the variable 'n' in 1:n half of 1 in decimal form.
So, what is half of 1 in decimal form?
If you said 0.5 OR 0.50, you are correct! And that is your answer !
Hope this helps :)

Name the longest and shortest side in the triangle.
Answer:
the answer is C Because the lm is the long side and mn is the short side
n is a positive integer. (i) Explain why n(n - 1) must be an even number.
Answer:
Since the equation is n(n-1) where n is even, (n-1) will result to an odd number and when multiplied the answer with n( an even number), this will result to an EVEN NUMBER. Therefore, in any number that n can substitute, whether even or odd, the answer will always result to an even number

Nicole wants to buy a charm bracelet. Summerfield Fine Jewelry charges $26 per charm, plus $19 for the bracelet. Flynn Jewelers, in contrast, charges $27 per charm and $11 for the bracelet. If Nicole wants to add a certain number of charms to her bracelet, the cost will be the same at either jewelry shop. How many charms would that be? What would the total cost of the bracelet be?
Answer:
There are 8 number of charms
Total cost = $227
Step-by-step explanation:
Let
Number of charms = c
Summerfield Fine Jewelry charges $26 per charm, plus $19 for the bracelet.
26c + 19
Flynn Jewelers charges $27 per charm and $11 for the bracelet
27c + 11
How many charms would that be ?
Equate the cost at both jewelry shop
26c + 19 = 27c + 11
Collect like terms
26c - 27c = 11 - 19
-c = - 8
c = 8
There are 8 number of charms
What would the total cost of the bracelet be?
Using any of the jewelry shop cost
Flynn Jewelers cost
= 27c + 11
= 27(8) + 11
= 216 + 11
= 227
Total cost = $227
Lines AB and CD are parallel. Find the measures of the three angles in triangle ABF.
What is the angle measurement for A, B, and F. (Make sure they are degrees)
Can you help me with this math question?
A = 42°
B= 23°
F = 115°
Step-by-step explanation:
The required measures of the three angles in triangle ABF are A = 23°, B = 42°, and F = 115°.
What are Alternate Interior Angles?Alternate Interior Angles are defined as the pair of angles created on the inner side of the parallel lines
Given that Lines AB and CD are parallel.
To determine the measures of the three angles in triangle ABF.
For finding ∠F,
∠CDF = 180° - 157° = 23°
∠F = 180° - ∠C - ∠CDF
∠F = 180° - 42° - 23°
∠F = 115°
However, if a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.
So ∠A = ∠CDF = 23°
And ∠B = ∠C = 42°
Thus, the required measures of the three angles in triangle ABF are A = 23°, B = 42°, and F = 115°.

Answer:
x=-127/10 or x= -12.7
Step-by-step explanation:
8(x−27)+49=87+28x
Step 1: Simplify both sides of the equation.
8(x−27)+49=87+28x
(8)(x)+(8)(−27)+49=87+28x(Distribute)
8x+−216+49=87+28x
(8x)+(−216+49)=28x+87(Combine Like Terms)
8x+−167=28x+87
8x−167=28x+87
Step 2: Subtract 28x from both sides.
8x−167−28x=28x+87−28x
−20x−167=87
Step 3: Add 167 to both sides.
−20x−167+167=87+167
−20x=254
Step 4: Divide both sides by -20.
−20x/−20
=

Which represents the symbolic notation of the compound statement below?
“Memorial Day is in July or parallel lines intersect.”
Answer:
Option (A)
Step-by-step explanation:
Statement 'p':
"Memorial Day is in July"
Statement 'q':
"Parallel lines intersect"
Since both the statement are joined by the 'OR',
Statements p and q will be joined by disjunction represented by the sign (∧).
Therefore, two statements will be represented as,
p ∧ q

The Martinez family is traveling to a play in Richmond. A round trip train ticket costs $8.00. Children under the age of 7 travel for half price. ($4.00) Tickets for the play are $14.00 for an adult and $6.00 for a child. Mr. And Mrs. Martinez will go with their children, Ricky, Ramona, and Thomas. Ricky and Ramona are 12 years old. Thomas is 6 years old. How much did the Martinez family spend for the train ride and play tickets?
Answer: The Martinex family spent $ 82 for train ride and play tickets.
Step-by-step explanation:
Round trip train cost = $ 8.00
For children it cost $ 4.00.
For adult, ticket for play costs= $ 14.00
For children , ticket for play costs= $ 6.00
Mr. And Mrs. Martinez will go with their children, Ricky, Ramona, and Thomas.
2 adults and 3 children ( only one of them is under 7.)
For train we consider only 1 as child rest as adult.
Train cost = 4 x($ 8.00)+ 1 x ($ 4.00)
= $ 32+4 = $36
For play , total cost = 2 x ( $ 14.00) + 3 x ($6)
= $(28+18)
= $ 46
Total spending ( combined) = $36+$ 46
= $82
So, the Martinex family spent $ 82 for train ride and play tickets.
A tape diagram. There are 65 students out of 100 students who ride the bus. There are question mark students out of 800 students who ride the bus. 65% of the 800 students at North High School ride the bus. How many students ride the bus? 100 multiplied by is equal to 800. 65 multiplied by is equal to . out of students ride the bus.
Answer:
answer one is 8
answer two is 8
answer three is 520
answer four is 520
answer five is 800
Step-by-step explanation:
There are 520 students out of 800 ride the bus,
65% of 800 is 520,
100 multiplied by 8 is 800.
What are ratios and proportions?The majority of the explanations for ratios and proportions use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. The foundation for understanding the numerous concepts in mathematics and science is provided by the two key notions of ratio and proportion.
Given,
1: There are 65 students out of 100 students who ride the bus. There are question mark students out of 800 students who ride the bus.
let x student out of 800 rides the bus
so both conditions 65/100 and x/800 are in proportions,
65/100 = x/800
x = 800*65/100
x = 520
2: 65% of the 800 students at North High School ride the bus.
65% of 800 = 65/100 x 800
65% of 800 = 520
3: 100 multiplied by is equal to 800.
let x multiplied by 100 is 800
x*100 = 800
x = 800/100
x = 8
Hence 520 students out of 800 ride the bus,
65% of 800 is 520,
100 multiplied by 8 is 800.
