Answer:
1/4x + 3
Step-by-step explanation:
The question said one-third(1/3) not one-fourth(1/4).
1/3x + 4 can also be written as x/3 + 4.
Answer:
number of pennies = 19
number of dimes = 19
number of quarters = 45 - 2 × 19 = 45 - 38 = 7
Step-by-step explanation:
The total number of coins in the box is 45 . The coins consist of pennies, dimes and quarters.
The number of pennies is equal to the number of dimes. The remaining number is the quarters. Therefore,
number of pennies = a
number of dimes = a
number of dimes = 45 - 2a
1 dime = 0.1 dollars
1 penny = 0.01 dollars
1 quarters = 0.25 dollars
Thee total cost can be expressed as follows
3.84 = a(0.01) + a(0.1) + 0.25(45 - 2a)
3.84 = 0.01a + 0.1a + 11.25 - 0.5
a
3.84 = -0.39
a + 11.25
3.84 - 11.25 = -0.39
a
-7.41 = -0.39
a
divide both sides by -0.39
a = -7.41/-0.39
a = 19
number of pennies = 19
number of dimes = 19
number of quarters = 45 - 2 × 19 = 45 - 38 = 7
Answer:
1: yes, because side MQ creates two right triangles inside the equalateral one, serving as the leg of both (reflexive property). In each right triangle, MQ would be the height.
2. (im unsure but i THINK i did it right)
1=yes
2=no
3=yes
3:The missing side would be 24.7
Step-by-step explanation:
Explanation for #3- A squared +B sqaured = C squared.
You know that one of the legs is 8 less than 42
42-8=34
34=one of the legs.
lets plug them all in: 42 squared - 34 sqaured = ?
1764-1156= 608
the square root of 608 is 24.7
so the missing side is 24.7
I hope this helps :)
Answer:
21 minutes
Step-by-step explanation:
35 ÷ 10 = 3.5
