Find Sin D and sin E! Write the answer as a fraction and as a decimal. Round to four decimal places, if necessary! Please help me!
Answer:
sine D = 0.9459
sine E = 0.3243
Step-by-step explanation:
Mathematically, sine is the ratio of the opposite to the hypotenuse
The hypotenuse is the longest side and we have it as 37 in the diagram given
the opposite to angle E is 12
So the sine of E = 12/37 = 0.3243
For D , its opposite is 35
The sine of D = 35/37
sine of D = 0.9459
In a bag there are blue sweets, red sweets and yellow sweets. The number of blue sweets is four times the number of yellow sweets. The number of red sweets is half the number of yellow sweets. Find the percentage of sweets in the bag that are yellow.
Answer:
18.18%
Step-by-step explanation:
The percentage of sweets in the bag that are yellow is as follows:
Let us assume the number of yellow sweets be x
So for number of blue sweets be 4x
And, the number of red sweets be 0.5x
So it could be written as
Blue Red Yellow
4 0.5 1
8 1 2
So for yellow, the percentage is
= 2 ÷ (8 + 1 + 2)
= 2 ÷ 11
= 18.18%

Amos scored 100 points while playing 3 rounds of a game.
Points
Round 1 - 30
Round 2 - 25
Round 3 - ?
Total - 100
How many points did he score in round 3?
Complete the steps to solve the problem.
1. What do you need to solve for this problem? Choose a variable to represent this unknown value.
2. Using the variable you chose, write an equation to represent this situation. (Hint: You may want to put the number of points in each round on one side and the total number of points on the other.)
3. Solve this equation to find how many points Amos scored in round 3. Show your work.
1. We can subtract the scores of the first and second rounds from the total score to obtain the score in the third round.
2. An equation including a variable to solve would be x + 30 + 25 = 100.
3. By solving the equation we obtain Amos scored 45 points in the third game.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
From the given information the score for her third round would be,
= (100 - 30 - 25).
= 100 - 55.
= 45.
Another way to solve this problem is assuming Amos scored 'x' in the third game.
Therefore, (30 + 25 + x) = 100.
55 + x = 100.
x = 100 - 55.
x = 45.

Which values for x, y, and z satisfy the equation 7xy/z=28
Answer:
try x= 4z/y
Step-by-step explanation:
* A Frog sits on a number line at point −10. It is allowed to make up to 4 jumps. First, it can make a jump of 8 units in either direction, or it can skip this jump. Then, it can make a jump 4 units long or skip this jump. Then, it can make a jump 2 units long, or skip this jump. And, finally, it can make a one-unit jump or skip it. Where can it be at the end? Answer: The possible numbers where frog could be are from
Answer and explanation:
Assuming the frog jumps from -10 for all jumps, if the frog decides to make all 4 jumps then :
8 units jump= -2 or -18
4 units jump= -6 or -14
2 units jump= -8 or -12
1 unit jump = -9 or -11
If the frog decides to make one jump then skip the others then:
Either it makes 8 units jump= -2 or -18
Or 4 units jump= -6 or -14
Or 2 units jump= -8 or -12
Or 1 unit jump = -9 or -11
If it decides to make 2 jumps and skip the others then:
Either it makes 8 units jump= -2 or -18
and 4 units jump= -6 or -14
Or 2 units jump= -8 or -12
and 1 unit jump = -9 or -11
Or any other mix of units of jump twice
If it decides to make 3 jumps and skip the others then:
Either it makes 8 units jump= -2 or -18
and 4 units jump= -6 or -14
and 2 units jump= -8 or -12
Or 1 unit jump = -9 or -11
and 4 units jump= -6 or -14
and 2 units jump= -8 or -12
Or any other mix of 3 jumps
If it decides to make no jump at all then the frog would remain at -10

Answer:
because 3 spheres is inside the cylinder and they are placed close together
=> The height of the cylinder is 3 times the diameter
=> the height is 18cm
the volume of the cylinder is 3,14.18.(6/2)² = 508,68
because 3 spheres have the same diameter
=> the volume of 3 spheres is 4.3,14.3³ = 339,12
=> the volume of the cylinder that is left empty is 508,68 - 339,12 = 169,56
Step-by-step explanation:
Answer:
The answer is 508,68
Step-by-step explanation:
Since the volume of the cylinder is equal to the area of the permanent base multiplied in the height
Since the radius of the base is equal to 3 and since the area of its cylinder is equal to
[tex]314 \times 3 \times 3 = 28.26[/tex]
When the height equal to 18
Then the volume equal to
[tex]28.26 \times 18 = 508.68[/tex]

The shape congruent to given figure is Figure 4.
Option D is correct.
What is congruency?Congruent figures have sides that are the same length and angles that are the same measurement. In other terms, two figures are said to be congruent when they are superimposed upon one another. Even when they are flipped or rotated, they perfectly fit on top of one another.
We have a figure which is similar to parallelogram.

OC. 20°, 60°, 100
O D. 45°, 45°, 45.
ос
E 50°, 509,80"
Answer:A
Step-by-step explanation:
Interior angles of a triangle ALWAYS have to be equal to 180
The sum of A is 180, however, those angles wont work because they have to be more close to eachother for it to be possible
The Triangle Inequality Theorem states the longest side must be shorter than the sum of the other 2 sides
