At her birthday party, marcie's guests ate 2/3 of her birthday cake and her family ate 1/4 of the cake. How much cake was left after her party?
Answer:
1/12
Step-by-step explanation:
So you start with an equation. 2/3 plus 1/4= ?.
Step 1: Find a common donominator.
Count by each number until they meat up.
3 6 9 12
4 8 12
Step 2: Multiply.
Basically, make sure that if you do something to the bottom you do the same to the top. You have
[tex]\frac{2}{3}[/tex] = [tex]\frac{?}{12}[/tex]. 3 times 4 is 12. 2 times 4 is 8. Your new fraction is [tex]\frac{8}{12}[/tex].
[tex]\frac{1}{4}[/tex] = [tex]\frac{?}{12}[/tex]. 4 times 3 is 12. 1 times 3 is 3. Your new fraction is [tex]\frac{3}{12}[/tex].
Step 3: Just Add!
[tex]\frac{8}{12} + \frac{3}{12}= \frac{11}{12}[/tex]
Step 4: Answer the question! The question asks "How much cake is left. You know that a whole cake is [tex]\frac{12}{12}[/tex]. So, [tex]\frac{12}{12} -\frac{11}{12} = \frac{1}{12}[/tex]

Help plz 13. Mildred is flying a kite on a 30 m string. The angle of elevation of the kite measures 40 degrees,
and Mildred's hand is 2 m above the ground. About how high is the kite off the ground?
a. 21.3 m
c. 19.3 m
b. 25 m
d. 23 m
Answer: 21.3m
Step-by-step explanation:
The height of the kite of the ground would be calculated as:
We have to calculate the question using a right angled triangle that has angle ACB as 90° while angle CAB will be 40°.
Therefore, the height of the kite would be:
= 30 sin 40 + 2
= 30 (0.6428 ) + 2
= 19.284 + 2
= 21.284 m
= 21.3 m

Step-by-step explanation:
Using PEMDAS, you would first do the exponent which is equal to 9. the following it you would do 5x9 which is 45 and divide it by 3 which gives you 15. finally you subtract the 9 from 15 and get 6.
Answer:
6
Step-by-step explanation:

Is y=4^2 an exponential function
Answer:
yes
Step-by-step explanation:
Yes, y = 4² is an exponential function.
What is exponential function?
" An exponential function is a mathematical function which can be expressed as y = [tex]a^{x}[/tex] where 'a' is any constant value not equals to 0 and 'x' is a variable which belongs to any real number."
According to the question,
y = 4²
If we compare with general form y = [tex]a^{x}[/tex] of exponential function we have,
a = 4
x = 2
Hence, we conclude that y = 4² is an exponential function.

2. 3rd row multiplied by the 3 columns : -4x² , 20x ,-24
Step-by-step explanation:
The table requires you to perform multiplication of the terms
The product is as follows;
1. 2nd row multiplied by the 3 columns
7x * x² = 7x³
7x * -5x = -35 x²
7x * 6 = 42
2. 3rd row multiplied by the 3 columns
-4 * x² = -4x²
-4 * -5x = 20x
-4*6 = -24

What is the quotient of 28 divided by 7 increased by 4
Answer:
8 beacaus the seven increased from 4
The quotient after increased by 4 is 8.
To calculate the quotient of 28 divided by 7, we perform the division and get:
28 ÷ 7
= 28/7
= (7 x 4)/ 7
= 4
Next, we are asked to increase this quotient by 4. Adding 4 to the quotient:
= 4 + 4
