Answer:
477 boys would be there.
Explanation:
boys to girls is 2:3
3 units ---> 716
1 units ---> (716/3)
then boys ---> (716/3) * 2
---> 477 boys
Or basically:
(716/3) * 2
477 boys

[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-5)}=\stackrel{m}{\cfrac{6}{5}}(x-\stackrel{x_1}{(-5)}) \\\\\\ y+5=\cfrac{6}{5}(x+5)\implies y+5=\cfrac{6}{5}x+6\implies y=\cfrac{6}{5}x+1[/tex]
Let f(x) = 1 3 x + 4. For what value(s) of x is f(x) = 2?
Step-by-step explanation:
If f(x) = 2 is the thing that we need to meet as a criterion, then what should we do to x?
simply equate these two.
f(x) = 2 = 13x + 4
2 = 13x + 4
13x = 2 - 4
x = -2 / 14.
Explain why an elevator with 3 people in it is less dense with an elevator with 50 people in it
Answer:
it has a lower mass/volume ratio
Step-by-step explanation:
Density is the ratio of mass to volume. An elevator will have the same volume, regardless of the number of people. The mass will increase with the number of people.
An elevator with 50 people in it will have a higher mass/volume ratio than an elevator with 3 people in it. Hence the latter is less dense.
__
Additional comment
50 persons would require an industrial elevator of perhaps 10,000 pound load capacity. There might be safety issues with carrying that many people.
how many soulutions are there to this equation? 3(3x−1)=6x−3
Answer:
See below.
Step-by-step explanation:
3(3x−1)=6x−3
9x-3=6x-3
+3 +3
9x=6x
-6x -6x
3x=0
/3 /3
x=0
There are no solutions.
-hope it helps
Answer:
x=0
Step-by-step explanation:
[tex]3(3x-1)=6x-3[/tex]
Use the distributive property to multiply 3 by 3x-1.
[tex]9x-3=6x-3[/tex]
Subtract 6x from both sides.
[tex]9x-3-6x=-3[/tex]
Combine 9x and -6x to get 3x.
[tex]3x-3=-3[/tex]
Add 3 to both sides.
[tex]3x=-3+3[/tex]
Add −3 and 3 to get 0.
[tex]3x=0[/tex]
Product of two numbers is equal to 0 if at least one of them is 0. Since 3 is not equal to 0, x must be equal to 0.
[tex]x=0[/tex]

Anyone know the answer for the whole question
Answer:
60 km
Step-by-step explanation:
a) A bearing is an angle, measured clockwise from the north direction.
(They are always given in 3 figures).
Therefore, the bearing of B from A is 090°
b) Method 1
Jafar drives from A to B = 2.4cm
As 1 cm represents 200 km, then 2.4 x 200 = 480 km
Kenzi drives from B to C = 1.2 + 1.5 = 2.7 cm
As 1 cm represents 200 km, then 2.7 x 200 = 540 km
To calculate how much further Kenzi drives that Jafar, subtract the distance Jafar drives from the distance Kenzi drives:
540 - 480 = 60 km
Method 2
The other way to do this is to calculate the difference in distance in centimeters and then convert the answer to kilometres by multiplying it by 200:
Jafar = 2.4 cm
Kenzi = 1.2 + 1.5 = 2.7 cm
Difference = 2.7 - 2.4 = 0.3 cm
Convert to km = 0.3 x 200 = 60 km

Answer:
14s^4-7s^2+15
Step-by-step explanation:
At the beginning the only bracket that is changing is the 3rd one because of the minus. (12s^4-6s^2+4s)+(6s^4-4s+27)-4s^4+s^2+12 then open the rest of the brackets. And start calculating.i will just to show you which ones u calculate together. (I'll separate the numbers depending on what they're squared to).
12s^4+6s^4-4s^4=14s^4
-6s^2-s^2=7s^2
27-12=15

Yolanda travels 403 km from Ottawa to Toronto. She travels 37% of the journey by car,
42.5% by train, and the rest by bus. What is the distance she travelled by bus?
Answer:
82.615 km
Step-by-step explanation:
100% - 42.5% = 57.5 - 37% = 20.5% by bus
403 km * 20.5 (0.205) = 82.615

A website is selling barbecue grills for $783. The site got the barbecue grills at a cost of $580. What is the mark-up, as a percentage?
Answer:
35%
Step-by-step explanation:
The price it cost the site to buy the grills was $580 but they were selling them for $783. So for each grill, they get a profit of $203. (783-580=203).
35% of $580 is 203 which adds up to $783
So therefore the markup rate is 35% I hope this helps!

B) similar: SSS similarity
C) similar: AA similarity
D) similar; SAS similarity
Answer:
A) not similar
Step-by-step explanation:
for the triangles to be similar the side lengths must be proportional.
For example:
99/35 should be equal to 121/44 but when we do cross multiplying we see they are not equal therefore the the triangles are not similar.

Answer:
14.42
Step-by-step explanation:
First, find the length of the leg of the bigger triangle (not the overall big triangle) using the Pythagorean Theorem. The overall length is 24, but we don't know the leg of the bigger triangle or the little triangle, so that is why we are going to find the length of the bigger triangle's leg. b = 12 and c = 20.
[tex]a^{2} + b^{2} =c^{2} \\a^{2} +12^{2} =20^{2} \\a^{2} +144=400\\a^{2} +144-144=400-144\\a^{2} =256\\\sqrt{a^{2}} =\sqrt{256}\\a = 16[/tex]
Next, find the leg of the little triangle by subtraction
24 - 16 = 8
Finally, you can find the hypotenuse of the little triangle by using the Pythagorean Theorem. a = 12 and b = 8
[tex]a^{2} + b^{2} =c^{2} \\12^{2} +8^{2} =2c^{2} \\64 +144=c^{2}\\208 = c^{2} \\\sqrt{208}=\sqrt{c^{2}} \\ c = 14.42[/tex]

The store paid $2. 70 for a book and sold it for $6. 20. What is the profit as a percent?.
Answer:
profit = 129.63% (to the nearest hundredth) as a percent of the price the store paid for the book
Step-by-step explanation:
Use the percentage change formula:
percent change = [ (difference between the initial value and the final value) ÷ initial value] x 100
= [ (6.20 - 2.70) ÷ 2.70 ] x 100
= [ 3.5 ÷ 2.70 ] x 100
= 37/27 x 100
= 129.6296296...
= 129.63% (to the nearest hundredth)

Math connection How many minutes does it take an electromagnetic wave to travel from the sun to the earth(150,000,000 km)
Answer: Approximately 8 minutes and 20 seconds
This is equivalent to 500 seconds.
==============================================
Explanation:
Any electromagnetic wave travels at the speed of light in a vacuum.
The speed of light is about 300,000 km per second.
time = distance/speed
time = (150,000,000 km)/(300,000 km per second)
time = 500 seconds
It takes about 500 seconds for an electromagnetic wave to go from the sun to the earth.
-----------
Divide by 60 to find the minutes and seconds
500/60 = 8 remainder 20
500 seconds = 8 minutes & 20 seconds
