1. A girl has eaten 60% of a cake .
a. What fraction of the cake has she eaten?
b. What percentage of the cake is left?
2.What percentage of 150 is 5
Answer:
#1
a. Covert % to fraction
60% = 60/100 = 3/5b. Whole is 100%, remaining is:
100% - 60% = 40%#2
5/150*100% = 3.33%What two numbers have a product of 16 and a sum of 8?
If 5^a =625, then find the value of a.
Answer:
a = 4
Step-by-step explanation:
note that 625 = [tex]5^{4}[/tex] , then
[tex]5^{a}[/tex] = [tex]5^{4}[/tex]
Since the bases on both sides are equal, both 5 then equate exponents, so
a = 4
Answer:
4
Step-by-step explanation:
Prime factorize 625
625 = 25 * 25 = 5 * 5 * 5 * 5
[tex]5^{a} = 625\\\\5^{a} = 5^{4}[/tex]
As base are same, compare the exponents
a = 4

what is the area of a quadrilateral with vertices at (-6,6), (-1,6),(-6,10), and (-1,10)
Answer: 20
Step-by-step explanation:
The area of a quadrilateral with given vertices is 20 square units.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
We have to determine the area of a quadrilateral with vertices at (-6,6), (-1,6),(-6,10), and (-1,10).
As per the attached graph, we can see that the dimensions of the rectangle are as follows:
Length (L) = 5 units
Width (W) = 4 units
Area of the rectangle = L × W
Area of the rectangle = 5 × 4 = 20 square units

A regular 16-gon has a radius of 10 meters
Part A: determine the length of the apothem
Part B: determine the perimeter of the polygon
Answer:
9 in
Step-by-step explanation:
For an n-sided polygon, the length of the apothem is ...
a = r·cos(180°/n)
We assume your problem statement is saying the radius is 10 inches. For a hexagon, n=6 and we have ...
a = (10 in)cos(30°) ≈ 8.66 in
Rounded to the nearest inch, the apothem is 9 in.
Answer:
9
Step-by-step explanation:
cos(30)=x/10
X=8.66

Answer:
[tex] m\angle D = 40\degree[/tex]
Step-by-step explanation:
[tex] m\angle DEC = 25\degree [/tex]
(Vertical angles)
[tex] m\angle DCE = 180\degree - 65\degree [/tex]
(Linear pair angles)
[tex] m\angle DCE = 115\degree [/tex]
In [tex] \triangle DCE[/tex]
By interior angle sum postulate of a triangle
[tex] m\angle D = 180\degree-(115\degree + 25\degree) [/tex]
[tex] m\angle D = 180\degree-140\degree[/tex]
[tex] m\angle D = 40\degree[/tex]
The price of a desktop computer decreases from $10360 to $1020. Find the percentage decrease its price
Answer: [tex]915.68\ \%[/tex]
Step-by-step explanation:
Given
Original Price=$10360
New Price=$1020
Percentage decrease in its Price is given by
[tex]\%\ \text{decrease}=\dfrac{\text{New-Original Price}}{\text{Original Price}}\times 100[/tex]
[tex]\Rightarrow \dfrac{10360-1020}{1020}\times 100=915.68\ \%[/tex]

What is the sum of the interior angles of a rectangle?
4°
360°
180°
90°
Answer: 180
The sum of the angles in a rectangle is given by (n-2)180 where n is the number of sides of the polygon and n is greater than or equal to 3. For a rectangle, n=4 thus sum of angles is (4–2)180 = 360 degrees. Each interior angle is 360/4 = 90 degrees.
Answer:
180⁰is the interior angle of a rectangle
You start at (8,0). You move left 6 units. Where do you end?
Answer:
(2, 0)
Step-by-step explanation:
Moving left just subtracts from the x coordinate (example: left 8 subtracts 8 from the x coordinate)

what are the first four terms of the sequence an=n2+4
Step-by-step explanation:
Given formula
an = n² + 4
Now the first four terms of the sequence are
a1 = 1² + 4 = 5
a2 = 2² + 4 = 4 + 4 = 8
a3 = 3² + 4 = 9 + 4 = 13
a4 = 4² + 4 = 16 + 4 = 20
The terms are
5 , 8 , 13 and 20.

Step-by-step explanation:
The sum of x and 3 times y is 5. The difference of x and y is 5. Write two equations and graph to find the value of y.
Answer:
for the first one, x + 3 * y = 5
and the second equation, x - y = 5
Step-by-step explanation:
the sum of two numbers means for example the sum of 5 and 8 is 13, so as an equation that is 5 + 8 = 13
the difference is the same thing as the sum but it's subtraction.
and then times is just multiplication.
if 15 workers complete a piece of work in 18 days in how many days will 27 workers complete the same work?
10 days is your answer
Answer:
15 workers =18 days to complete work
1 worker =18×15=270 days to complete work
27 worker=270/27=10 days to complete work
Which budget categories are both variable expenses?
Answer:Utilities and Groceries
Step-by-step explanation:Variable expenses are defined as such because the amount you spend may vary each month. Although variable costs are quite often discretionary expenses, some may be necessities. Buying gas for your car each month is a variable expense, as are car repairs and maintenance. Grocery shopping is also a variable expense.

In Juan's coin bank there are nickels (n),
dimes (d), and quarters (q). The number of
quarters is one-quarter the number of dimes, and
the number of nickels is twice the number of
quarters. The total value of the coins is $6.00.
Find the number of each type of coin. [Show all
work.]
Answer:
The answer is 8 quarters, 16 nickles, and 32 dimes
Step-by-step explanation:
First, the equation would be (2/4d) x 5 +d x 10 +1/4d x 25= 600 (Don't put 6.00, that's dollars. We put 6 dollars into cents to make it easier.) Then we slowly start to solve: 10/4d + 10d + 25/4d = 600 10d+40d+25d/4 = 600 (Put all of that over 4, not first 25d) 75d= 600 x 4 d=600 x 4/75 (same here put everything over 75) d=32 So then n= 2 x 32/4 = 16 Then n would be equal to : 1/4d= 1/4 x 32 = 8 So your answer would be 8 quarters, 16 nickles, and 32 dimes.Hope this helped :)

(Prove that):
2 sin 70. cos 20 = sin 90 + sin 50
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
2sinxcosy = sin(x + y) + sin(x - y) , then
with x = 70 and y = 20
2sin70cos20
= sin(70 + 20) + sin(70 - 20)
= sin90 + sin50
= right side , thus proven
