the strategy used: 10 1/2 - 3/4
Answer:
9 3/4
Step-by-step explanation:
Strategy: first cancel the fraction part of the mixed number, then subtract the remaining fraction from the integer obtained.
10 1/2 - 3/4 = 10 1/2 - 1/2 - 1/4
= 10 -1/4
= 9 3/4
__
Strategy: turn the subtracted fraction into a whole number by adding 1/4 to both parts of the problem, then subtract the whole number.
10 1/2 - 3/4 = (10 1/2 +1/4) -(3/4 +1/4)
= 10 3/4 -1
= 9 3/4
_____
We assume that you know that 1/2 + 1/4 = 3/4, or 3/4 -1/2 = 1/4. If you need to, you can get there by using the equivalent: 1/2 = 2/4.

Step-by-step explanation:
A health club charges an initiation fee of $50. Members then pay $45 per month. You have $400 to spend on a health club membership. For how many months can you afford to be a member? Let n represent the number of months you can pay for a membership.
Answer:
8 monthsStep-by-step explanation:
In this problem we must first of all write the inequality that describes the problem.
Given that
1. you have a limit of $400
2. there is an initial fee of $50
3. monthly payment is $45
let the number of months be n
therefore
[tex]50+45n\leq 400\\\\45n\leq 400-50\\\\45n\leq350[/tex]
Divide both sides by 45 we have
[tex]n\leq \frac{350}{45} \\\\n=\frac{70}{9} \\\\n= 7.77\\\\[/tex]
approximately you are going to be member for 8 months
Nadia is mountain climbing. She started at an altitude of 19.26 feet below sea level and then changed her altitude by climbing a total of 5,437.8 feet up from her initial position. What was Nadia's altitude at the end of her climb?
Answer: 5418.54 feet
Step-by-step explanation:
Given: Nadia started at 19.26 feet below sea level.
She climbed a total of 5,437.8 feet up from her initial position.
Since we take negative integers to show depth .
Here, 19.26 feet below sea level. means - 19.26 feet respective to sea level

B(-a,-a)
C(-V3a, V3a)
AB=V(a+a)^2+(a+a)^2=V4a^2+4a^2=V8a^2
AC=V(a+V3a)^2+(a-V3)^2=Va^2+2a^2V3+3a^2+a^2-2a^2V3+3a^2=V8a^2
BC=V(-a+V3a)^2+(-a-V3a)^2=V8a^2
so AB=AC=BC
Area=AB^2V3/4=8a^2*V3/4=2V3a^2

Complete question:
In 2016, the city of Rio de Janeiro had a population density of 5377 people/km2.
What was the population density of Rio in people per square meter?
Answer:
0.005377 peope/m²
Step-by-step explanation:
Given that :
Population density of Rio in 2016 = 5377 people/km²
To obtain population density in people per square meter, we convert 5377people/km² to people per m²
Recall:
1000 m = 1km
Hence,
5377 people/km² = 5377 people / (1000²)m
= (5377/1000000)people/m²
= 0.005377 peope/m²

Work out the angles marked x in each diagram you must show your working
Answer:
x = 125°Step-by-step explanation:
Since ∆ ABC is a triangle the sum of it's angles add up to 180°
In order to find x we must first find [tex]\angle[/tex] AED
Let [tex]\angle[/tex] AED = E
To find [tex]\angle[/tex] AED add up all the angles in the triangle and equate it to 180°
That's
35 + 90 + E = 180
125 + E = 180
E = 180 - 125
E = 55°
E and x lie on a straight line
So we have
x + 55 = 180°
x = 180 - 55
x = 125°Hope this helps you

i will mark brainliest
Answer:
174 seconds.
Step-by-step explanation:
So there was a total of 7 songs.
And it took a total of 20 minutes and 18 seconds to play them all.
20 minutes and 18 seconds is the same as 20(60)+18=1218 seconds.
Thus, the average number of seconds per song was:

Answer:
AA Theorem
Step-by-step explanation:
In order to prove AB/AE = AC/AD, we need to prove that the triangles are similar. The AA Theorem says that if two triangles share two congruent angles, then the triangles are similar. The given states that ∠ABE ≅ ∠ACD, which means these two angles are congruent.
For the second angle, both triangles have the angle by point A. These angles can be written as ∠A ≅ ∠A. These angles are congruent because of the reflexive property.
Because we have proven these triangles to be simliar, we know the proportion AB/AE = AC/AD is correct because corresponding sides of similar triangles are proportional.
If B is the midpoint of AC, solve for x, and find the lengths of AB, BC, and AC.
Please show all work and not just the answers.
Answer:
x = 2
AB = 15
BC = 15
AC = 30
Step-by-step explanation:
Given that B is the midpoint of AC, then AB = ½ of AC.
AB is given as 3(3x - 1),
AC = 5(2x + 2),
Therefore:
[tex] 3(3x - 1) = \frac{1}{2}*5(2x + 2) [/tex]
Solve for x
[tex] 9x - 3 = \frac{5}{2}(2x + 2) [/tex]
Multiply both sides by 2
[tex] 2(9x - 3) = \frac{5}{2}(2x + 2)*2 [/tex]
[tex] 18x - 6 = 5(2x + 2) [/tex]
[tex] 18x - 6 = 10x + 10 [/tex]
[tex] 18x - 10x = 6 + 10 [/tex]
[tex] 8x = 16 [/tex]
Divide both sides by 8
[tex] x = 2 [/tex]
[tex] AB = BC = 3(3x - 1) [/tex]
Plug in the value of x
[tex] AB = BC = 3(3(2) - 1) [/tex]
[tex] = 3(6 - 1) = 3(5) = 15 [/tex]
[tex] AC = 5(2x + 2) [/tex]
[tex] AC = 5(2(2) + 2) [/tex]
[tex] AC = 5(4 + 2) = 5(6) = 30 [/tex]

What scale factor is used to go from Figure F to Figure
G? What scale factor is used to go from Figure G to
Figure F?
Scale Factor to go from F to G = 3/4
Scale Factor to go from G to F = 4/3
===============================================
Explanation:
Note the sides labeled 4 and 3 are both opposite the angles that have two tickmarks. Therefore, these two sides correspond to one another.
Because of the similar triangles, the corresponding sides are in proportion. The scale factor is 3/4 meaning the smaller triangle has side lengths 3/4 as large compared to the larger triangle.
Put another way, we have a 25% reduction in the side lengths because 3/4 = 75% and 100% - 75% = 25%
So far, all of this applies when figure F is the preimage and G is the image. If we reverse things, then apply the reciprocal to 3/4 to get 4/3. Now G is the preimage and we go from smaller to larger.
------------
Side notes:
If the scale factor is smaller than 1, but still positive, then the image is smaller than the preimage. We have an image reduction.If the scale factor is larger than 1, then the image is larger than the preimage. We have an image enlargement.The required scale factor for the given transformation is given as 3/4.
Given that,
Two triangles have been shown, is to discuss the transformation and scale factor of the triangle.
The scale factor is defined as the ratio of modified change in length to
Here,
The given figures are similar in shape but not in size,
If the shapes is similar then the ratio of the corresponding sides describes the scale factor between the figures,
So,

12 people fit comfortably in a 5 x 5 foot square.use this value to estimate of a crowd that is 10 feet deep on both sides of the street along a 1 mil section of a parade route
Answer:
48 people
Step-by-step explanation:
It states that 12 people fit into a 5 x 5 ft² area.
Here, we are given the length and breath of the side, both 5 ft. And from that, we can estimate the area of the place.
Area of a square is gotten by multiplying both sides together, and thus
5 * 5 = 25 ft²
We are told 12 people fit into 25 ft². In order to get the number of people that fit a 10 x 10, we first need to calculate the area.
We already have the length and breadth to be 10 ft each, so
Area = 10 * 10 = 100 ft²
Now, we calculate.
If
12 people fit into 25 ft²
x people will fit into 100 ft²
If we cross multiply, we have
1200 = 25x
We then divide both sides by 25
x = 1200 / 25
x = 48
Therefore, 48 people will fit into a 10 x 10 ft area
