Answer:
The temp got colder by -1
Step-by-step explanation:
The difference of -3 to -4
-4 + -3 = -1
Subtracting fractions with a common denominator, you subtract only the numerator, which are 4 and 3, and keep the common denominator the same, underneath the fraction. It is just subtracting 4 and 3 and putting them in a fraction, just like 4-3
Answer:
Sophia now has 39 cents.
Step-by-step explanation:
One quarter = 25 cents
Since Sophia had 64 cents until she spent 25 cents (1 quarter).
So we subtract 25 cents from 64 cents.
Therefore, Sophia now has 39 cents.
Answer:
4
Step-by-step explanation:
The diagram shows that the one triangle can be divided into two equal right triangles. Because of this, you can use the Pythagorean Theorem to solve this problem. a and b are the two sides of the angles, and c is the hypotenuse.
The given lengths are 5 as the hypotenuse and 3 as one length. (You have 3 as a given length because the two triangles have a length of 6 on one side. 6/2 = 3)
a² + b² = c²
a² = c² - b²
a² = 5² - 3²
a² = 25² - 9²
a² = 16
a = 4
I believe you would do 2 times 3, which gives you 6. 3 is for the number of coin tosses, and 2 is the number of sides of a coin.
