Answer: 78/5
Step-by-step explanation:
To simplify this fraction, we should get rid of 15 in order to only have a numerator and a denominator. We would first multiply 15 with 5.
15 * 5 = 75
Then we would add 75 to 3.
75 + 3 = 78
We now have our numerator for our simplified fraction.
78/5
The square in the middle has an area of 1 square unit. What I'd the area of the entire rectangle in square units? Explain you reasoning
The entire rectangle is 4 square units because the two triangles on the top put together makes the same shape as the square in the middle, which makes it 1 square unit. And the two bigger triangles on the bottom can create two squares if you break them apart and rearrange them again. So all of those shapes put together equals 4 square units.

Answer: 99.56%
Step-by-step explanation:
Well assuming we're working with a full poll of all 100% of students, and only 0.44%, so 100 - .44 is 99.56
An examination paper consists of 12 questions divided into two parts A and B.
Part A contains 7 questions and Part B contains the remaining questions. A candidate required to attempt 8 questions selecting at least 3 from each part. In how many ways can the candidate select the question
Answer:
420 waysStep-by-step explanation:
There are 3 possible scenarios
1) 5 questions from A and 3 questions from B:
[tex]_7C_5*_5C_3=7!/5!2!*5!/3!2! = (6*7)/2*(4*5)/2=210[/tex]2) 4 questions from each part:
[tex]_7C_4*_5C_4=7!/4!3!*5!/4!1! = (5*6*7)/(2*3)*5=175[/tex]3) 3 questions from A and 5 questions from B:
[tex]_7C_3*_5C_5=7!/4!3!*1 = (5*6*7)/(2*3)=35[/tex]Total number of ways:
210 + 175 + 35 = 420Answer:
Student has to do 8 questions such that he does at least 3 questions from both the sets
How can he go about (Set I, Set II) =(3,5) or (4,4) or (5,3)
So, total number of ways of doing this is given by
[tex]5c_{3} \times 7c_{5} + 5c_{4} \times 7c _{4} + 5c_{5} \times 7c _{3}[/tex]
[tex] = (10)(21) + (5)(35) + (1)(35) = 210 + 210 = 420[/tex]

an amsuement park sells child and adult tickets at a ratio of 8:1. On Saturday they sold 147 more child tickets than adult tickets. How many tickets did the amusement park sell on Saturday?
Step-by-step explanation:
Given that, when the difference is 147 7 times the number of adult tickets sold will be 147. Therefore, the number of adult tickets sold will be 21 and the number of children tickets sold will be 168. TheTOTAL TICKETS SOLD is 21 + 168 = 189.Simplify.

Angles are
180-80=100°x+5=40+5=45°x-5=40-5=35°No sean was wrong
Answer:
Sean is not correct. The answers are 100°, 35° and 45°.
Step-by-step explanation:
In my working, I labeled the part without a variable as a°.
Step 1: a° + 80° = 180° ( angles on a straight line sum up to 180° )
Step 2: a° = 180° - 80°. This is because 80 moves from the left side of the equation to the right side of the equation which affects it's sign( from + to -)
Step 3: a° = 100° . Subtract 80 from 180.
So we know that 100 is correct. Let's find the remaining angles.
Step 4: a° + ( x - 5 )° + ( x + 5 )° = 180° ( angles in a triangle sum up to 180°)
Step 5: 100° + x - 5° + x + 5° = 180°. Fix in the values of each variable correctly. Here we only know the value of variable a.
Step 6: (100° - 5° + 5°) + (x + x) = 180°. Group like terms to make calculations easier.
Step 7: 100° + 2x = 180°. -5+5 is the same as 5-5 which would give you 0. 0 + 100° is 100°.
Step 8: 2x = 180° - 100°. Move like terms to one side.
Step 9: 2x= 80°. Subtract 100° from 180° to get 80°
Step 10: 2x/2 = 80°/ 2. Divide both sides by 2.
Step 11: x= 40°. But this isn't the final answer. This is just the answer for all the x you see in the diagram. So fix in the values correctly.
Step 12: ( x-5° ). State it for your teacher to know which question you are given an answer to. From our calculations, we know that x = 40°.
Step 13: (40° - 5°)
Step 14: ( 35°). 40 minus 5 is 35.
Step 15: 35°. multiply the figure in the bracket by one. We can't leave our answer in the bracket.
Step 16: (x + 5). Using the same knowledge, fix in the values and do as the operation sign says.
Step 17: ( 40° + 5 °)
Step 18: (45°)
Step 19: 45 °
Step 20: Sean is not right because the angles in the triangle are 100°, 35° and 40°.
Which number is farthest away from 0?
-16
-39
7
12
-39 is the furthers away from 0
this is because if you draw a number line -16 would be 16 away from 0, 12 would be 12 away from zero and 7 would be 7 away from 0...
| - - - - - - - - - - - - - - - |- - - - - - | - - - - |
16 0 7 12
and -39 would be 39 digits away from 0, therefore its the furthest away from 0
Hope this helped you- have a good day bro cya)
Answer:
-39, or the absolute value of 39 is farthest from 0.
Step-by-step explanation:
-16 is 16 units from 0.
-39 is 39 units from 0.
7 is 7 units from 0.
12 is 12 units from 0.
39 > 16
39 > 7
39 > 12

Answer:
f(x) = 8x
Step-by-step explanation:
The linear equation given in the form of a table is shown as:
[tex]\left[\begin{array}{ccc}x&f(x)\\3&24\\4&32\\5&40\\6&48\end{array}\right][/tex]
Because the equation is linear, in order to find the equation written in slope-intercept form, divide the rise (f(x)) by the run (x):
24 ÷ 3 = 8
32 ÷ 4 = 8
40 ÷ 5 = 8
48 ÷ 6 = 8
Because the quotient for each relation is 8, the linear equation can be written as f(x) = 8x.

We observe two angles and the included side of ABC are congruent to two angles and the included side of DBE:
∠A ≅ ∠D∠C ≅ ∠ EAC ≅ DEThis is called ASA
Answer:
ASA postulate
Answer C is correct
Step-by-step explanation:
<ACB = < BED (Angle)
AC = DE (Side)
<CAB = < BED = 90° (Angle)

Answer:
7.84 to 8.16 ounces
Step-by-step explanation:
The difference between the actual amount in the bottle and the target amount of 8 ounces can be at most 2% of 8 ounces. That amount is ...
0.02×8 oz = 0.16 oz
The amount in the bottle can be this much higher:
8 + 0.16 = 8.16 . . . ounces
or, it can be that much lower:
8 - 0.16 = 7.84 . . . ounces
The range of values the bottle could contain is from 7.84 ounces to 8.16 ounces.
