Answer:
40
Step-by-step explanation:
d=rt
300=r(7.5)
300÷7.5=r
40=r
Answer:
bg gbybybbybyv in his ubuvyvyvy tvt the yn
Step-by-step explanation:
The numbers 1 to 9 are 9 digits
The numbers 10 to 99 are 90*2 = 180 digits.
You have written 189 digits and must write another 1000 - 189 = 811 digits.
Every number from 100 to 500 have 3 digits.
811/3 = 270 1/3
So you write 270 numbers: 100 to 369
And then you will write the first number from 370 (the 1000th digit). This digit is 3.
Answer:
she spends 20 minutes on each activity
Step-by-step explanation:
because 60 / 3 equals 20 therefore she takes 20 minutes on each activity so the answer is 20 minutes she eats breakfast
<u>4.</u> Since angles 1 and 2 are supplementary, this means they add up to 180 degrees. Make them add up to 180 in an equation and solve for a. Substitute a back into m∠2 to find your answer.
(11a + 19) + (6a - 9) = 180
Combine like terms.
17a + 10 = 180
Subtract 10 from both sides.
17a = 170
Divide both sides by 17 to isolate and solve for the variable a.
a = 10
Substitute 10 for a into m∠2.
6(10) - 9 ==> 60 - 9 = 51
The measure of angle 2 is 51 degrees.

<u>5.</u> Since Ray BD bisects ∠ABC that means that both the formed angles are equal to each other, so make them equal to each other in an equation.
5y - 3 = 2y + 12
Add 3 to both sides.
5y = 2y + 15
Subtract 2y from both sides.
3y = 15
Divide both sides by 3 to isolate and solve for the variable y.
y = 5
