Answer:
5 times the compared amount.
Step-by-step explanation:
Answer:
The ratio means for everything 5 of something (lets call it x), y will always have 1.
Example - Jordan buys 5 cookies from the bakery. The special offer of the day allows him to receive one free brownie. This is an example of 5/1 because every 5 cookies, Jordan receives 1 brownie.

please help!! using the pythagorean theorem !!
Answer:
≈8.66
Step-by-step explanation:
a²+b²=c²
5²+b²=10²
25+b²=100
25+b²-25=100-25
b²=75
b=√75
≈8.66
pls mark me as brainliest!
Answer:
8.66
Step-by-step explanation:
You're solving for b.
first, use the formula
c = a^2 +b^2
b = c^2 -a^2 = 10^2 - 5^2 = 8.66025
Don't forget that you have to square root it.
You are given that a 7.6.54 to 3 significant figures) and b = 123 (to 3 significant figures):
Calculate upper and lower bounds for a+b, give your answers to 3 significant figures:
[tex]\\ \sf\longmapsto a+b[/tex]
[tex]\\ \sf\longmapsto 123+76.5[/tex]
[tex]\\ \sf\longmapsto 199.5[/tex]

A map of Pennsylvania has a scale of ¾ inch to 25 miles. If Pittsburgh and Philadelphia are 9 inches apart on the map, how many miles apart are the two cities?
Answer: 300
Step-by-step explanation:
0.75 inches : 25 miles
we can times 0.75 by 12 to get 9, we have to do the same thing on the other side.
9inches : 300 miles

bubba's gym charges a $100 membership fee and $10 per visit.
write an expression that represents the cost of "x" visits: C=_______
Answer:
C=100+10x
Step-by-step explanation:
its 10$ per visit and x represents the number of visits. and you get a 1 time membership fee of 100 so its 100+10x=C c stand for cost.

CAN ANYBODY HELP ME What is the 100th term in the sequence beginning with -45, -43, -41, -39, ...?
Group of answer choices
153
150
155
200
55
Answer:
153
Step-by-step explanation:
Since the given sequence is arithmetic because it has common difference.
-43-(-45) ,= -43+45 = 2
-41+43 = 2
-39+41 = 2
Therefore, the common difference is 2.
General Term
[tex] \displaystyle \large{a_n = a_1 + (n - 1)d}[/tex]
Since we want to find the 100th term, substitute n = 100.
We know common difference which is 2 and defined as 'd'; substitute d = 2
a1 means first term so:-
[tex] \displaystyle \large{a_{100}= - 45 + (100 - 1)2} \\ \displaystyle \large{a_{100}= - 45 + (99)2} \\ \displaystyle \large{a_{100}= - 45 + 198} \\ \displaystyle \large{a_{100}= 153}[/tex]
tập nghiệm của phương trình 3tan+√3=0
Answer:
if 0° ≤ x ≤ 360°
x = 150° or x = 330° (5/6 π , 11/6 π)
if x can be beyond 2π (360°) , above or below
x = 5/6 π + 2nπ or x = 11/6 π + 2nπ
Step-by-step explanation:
3 tanx = -√3
tan x = - 1/√3
if 0° ≤ x ≤ 360°
x = 150° or x = 330° (5/6 π , 11/6 π)
if x can be beyond 2π (360°) , above or below
x = 5/6 π + 2nπ or x = 11/6 π + 2nπ

share 40 pounds in the ratio 1:4 between tim and sam
Answer:
Add the ratio together: 1 + 4 = 5
Divide total by 5: 40/5 = 8
Multiply 8 by each portion of the ratio:
8 x 1 = 8
8 x 4 = 32
Time gets 8
Sam gets 32
Lourdes plans to jog at least 1.5 miles. Write and solve an inequality to find x, the number of hours that Lourdes will have to jog..
Answer:
An inequality compares two or more variables by using the <, >, ≤, or ≥ signs.
The number of hours Lourdes will have to jog is 0.4 hours
From the given parameters:
Lourdes plans to jog for at least a distance of 1.5 miles
If Lourdes can jog averagely at the speed of 3.75 mph
Then,
the inequality that can represent the information can be written as:
= 1.5 miles ≤ 3.75 (x) miles/hour
Solving the inequality;
= 1.5 ≤ 3.75 (x)
Making (x) the subject of the formula, we have:
x = 0.4 hours
Therefore, we can conclude that the number of hours lourdes will have to jog is 0.4 hours

Let f(x)=8x−6. What is the value of f(12)?
Answer:
f(12) = 90
Step-by-step explanation:
This is more of a notation problem than anything else.
The x on the left means that the variable is x. That sounds weird I know, but it starts out this way.
f(variable) = 8*variable - 6
Where you see the word variable, you put the letter x and that gives you the question.
f(x) = 8*x - 6
That is math shorthand for whatever you see on the left, like an x or in this case 12, you put the value 12 in for x on the right. It will look like this.
f(12) = 8*12 - 6 Now it just becomes a calculator problem.
f(12) = 96 - 6
f(12) = 90

Six times the quantity, x-2, is 24. Find the number
Answer:
x = 6
Step-by-step explanation:
it states 6 times the quantity x - 2, so the expression would be 6 ( x - 2 ) = 24. first multiply because you cannot add or subtract unlike terms. so 6 multiplied by x and -2, the expression would be (6x - 12) = 24. add 12 to 12 so you cancel the coefficient. but when adding to the constant add to the sum. now it is 6x = 36. since 6x is multiplication, divide 6x by 6 to isolate the variable, but divide the answer, 36 divided by 6 is 6. therefore x = 6. hope this helps

Find the measures of two supplementary angleš if the difference between the
measures of the two angies is 35º
Answer:
<1 = 107.5 degrees
<2 = 72.5 degrees
Step-by-step explanation:
<1 = x
<2 = x -35
x + x - 35 = 180
2x = 180+35
x = 215/2
x = 107.5
<1 = 107.5
<2 = 72.5
