Answer4/6 or 8/12 i think sorry if im wrong
Step-by-step explanation:
Answer:
you have 1/3 chances
Step-by-step explanation:
A cube has six sides
6 + 6 = 12
you have to roll higher than 1 and 2, which both sides have
4/12 = .3333 = 1/3
Hope this is correct
can someone help me do this one problem please like I need help Right now
Answer:
x= 11/12
Step-by-step explanation:
you have to make 1/3 equivalent to 7/12 so now you get 4/12+7/12= 11/12

Note however that the shape of the diagram does not match the numbers on it. So either it is poorly drawn, or I am misinterpreting the numbers. It seems pretty clear though that the image is incorrect, as the two segments both marked as being 25 units long are represented at different lengths.
Step-by-step explanation:
The image here does not fit the numbers. Note that the bottom triangle has two sides with given lengths of 25 units, but they are drawn as different lengths.
Let's plough on though, and find a better image of what that shape would be.
Starting with the bottom triangle:
Given that the two sides of the bottom triangle are both 25 units in length, we know that it is an isosceles triangle (despite its depiction otherwise). Because of that, we know that the two bottom angles are equal. We already know that the top corner is 90°, and that the sum of the angles in a triangle must be 180° This means that the two bottom angles (again, contrary to how its drawn) are both equal to 45°
Now that we have that information, we can look at the over triangle. We know that the bottom right corner is 45°, and that the bottom left is 90°. That tells us that the top angle is also 45°.
With that said, we can redraw the image with the proper proportions. See the attached image.
That very much simplifies things. The line separating the triangles bisects the hypotenuse of the larger triangle, meaning that x is also equal to 25.
To be sure of that though, we can prove it another way. Given that the bottom two corners are both 45, we can use the sine rule to measure x. The sine rule states that the sine of each angle in a triangle has the same ratio to their opposite sides. Usually expressed as:
[tex]\frac{a}{\sin A} = \frac{b}{\sin B} = \frac{c}{\sin C}[/tex]
where a, b and c are the side lengths, and A, B and C are the angles of the corners opposite those sides.
With that we can take the two parts of the overall triangle's hypotenuse, 25 and x, and say that each of those divided by the sine of the angle opposite them is equal to each other:
[tex]\frac{x}{\sin 45} = \frac{25}{\sin 45}[/tex]
This turns out to be very easy to solve, as both sides have the same denominator. As a result, we can just multiply both sides by sin 45, giving us:
x = 25.
Amelia invests money in an account paying simple interest. She invests $180
and no money is added or removed from the investment. After one year, she
has $187.20. What is the simple percent interest per year?
Answer:
4%
Step-by-step explanation:
100% represents the starting balance: $180.
Method 1
Express the ending balance as a percentage of the starting balance:
$180
1.04
1.04 times 100=
1.04×100=
104%
Subtract the starting 100% to get the percent interest:
4%
Method 2
$187.20−$180=
$7.20
$180
$7.20
0.04
0.04 times 100=
0.04×100=
4%
if $45 is divided into the ratio 4:5 the smaller part is A. $1.50 B.$3.50 C.$4.50 D.$24.50 Asap
Answer:
Step-by-step explanation:
When you do 45 divided by 9 you get 5.
45 / 9 = 5
To figure out what the smaller number (in this the 4) equals,
you have to do 4 times 9 to get 36.
4 * 9 = 36
So your answer is 36.
(3ax + 4a) - (9x + 15a)
Answer:
3ax−11a−9x
Step-by-step explanation:
3ax+4a−(9x+15a)
Distribute the Negative Sign:
=3ax+4a+−1(9x+15a)
=3ax+4a+−1(9x)+−1(15a)
=3ax+4a+−9x+−15a
Combine Like Terms:
=3ax+4a+−9x+−15a
=(3ax)+(4a+−15a)+(−9x)
=3ax+−11a+−9x
You are trying to heat up a cup of water with a butane lighter.
1) How much heat is transferred to the water if 200 g of water with a specific heat capacity of 4.184Jg°C changes from 22.3ºC to 35.7ºC? Answer in kJ.
2) If you burn 0.23 g of butane, what is the heat of combustion of butane in kJ/g?
Answer:
Step-by-step explanation:
Remark
The formula for this is
Heat = m * c * Δt
Givens
Heat = unknown
m = 200 grams
c = 4.184 Joules / grams oC
Δt = the change in temperature = 35.7 - 22.3 = 13.4
Solution
Heat = 200 * 4.184 * 13.4
Heat = 11213 Joules
Heat = 11.2 Kj
It's hard to get the correct number of sig digs because the 200 is not qualified in any way.
Part 2.
This can really puzzle you until you know that heat given up = the heat taken on. The heat taken on was 11.2 Kj. The Butane lighter must have given that heat on.
Heat of Combustion = Heat Given Up / Number grams burned.
Heat of Combustion = 11.2 Kj / 0.23 grams
Heat of Combustion = 48.8 Kj / gram

Answer:
z = 24
Step-by-step explanation:
35/30 = 7/6
28/7 = 4
6 x 4 = 24
28/24 = 7/6
Answer:
x = 24
Step-by-step explanation:
All you have to do is cross multiply like this..
30 x 28 = 35 x X
=
x = 30 x 28/35
30 x 28 = 840 / 35 =
24
So x is equal to 24

The table gives the probabilities that orphaned pets in animal shelters in six cities are one of the types listed. The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is _____ %. The probability that a randomly selected orphaned dog in the same animal shelter in Austin is a Chihuahua is _____ %. (Round to the nearest hundredth.)
For all the dogs: you have 2.65+2.46+3.67+2.91 = 11.69%
Now, the probability of getting a chihuahua would be 3.44/11.69=0.2942= 24.92
Step-by-step explanation:
there ya go!!
Answer:
The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is 11.71% .
The probability that a randomly selected orphaned dog in the same animal shelter in Austin is a Chihuahua is 29.37% .
Step-by-step explanation:
2.76% + 2.86% + 3.44% + 2.65% = 11.71%
11.71 / 3.44 = .2937
.2937 = 29.37%

Answer:
16.8 cubic centimeters
Step-by-step explanation:
3 cm * 4 cm * 1.4 cm = the volume of the prism
3 * 4 = 12
12 * 1.4
1 + 0.4 = 1.4
12 * 1 = 12
12 * 0.4 = 4.8
12 + 4.8 = 16.8
the volume of the prism is 16.8 cubic centimeters
Q2: How do you use the distance formula and slope formula to classify quadrilaterals
Answer:Distance formula and the slope formula can be used to classify a quadrilateral as using the slope formula, the slopes can tell what angles it have or if lines are perpendicular or not.
Distance formula can be used to find the length of the sides and it also tells that whether it is right triangle or isosceles or an equilateral triangle.

£25 = 700 rubles, how many £ are in 1,260 rubles?
£
Answer:
45
Step-by-step explanation:
25 = 700
Y = 1260
Now you need to do cross multiplication .
25 X 1260=700Y
Since it's in a multiplying form you can simplify by dividing 700 by 25
1260=700Y/25
1260=28Y
Y=45
