The temperature at 6:00 a.m. was ‐3.5°C. From 6:00 to 7:00, the temperature increased 2.5°C. From 7:00 to 8:00, it decreased by 0.25°C, and from 8:00 to 11:00, the temperature dropped 3.25°C. Which expression shows the temperature in °C at 11:00 a.m.?

Answers

Answer 1

Answer:

The expression that shows the temperature in °C is $-3.5+2.5+(-0.25)+(-3.25)$ .

Step-by-step explanation:

Step 1:

The initial temperature at 6.00 am was $-3.5$ °C.

Step 2:

From 6.00 to 7.00 am, the temperature increased by another 2.5°C, so the temperature at 7.00 am was $(-3.5 + 2.5)$ °C.

Step 3:

From 7.00 to 8.00 a.m, the temperature decreased by another 0.25°C, so the temperature at 8.00 am was $(-3.5+2.5+(-0.25))$ °C.

Step 4:

From 8.00 to 11.00 a.m, the temperature dropped by another 3.25 °C, so the temperature at 11.00 am was $(-3.5+2.5+(-0.25)+-(3.25))$ °C which is represented by the fourth option.

What is 36/80 in lowest terms fraction wise

Answers

To simplify a fraction (reduce it to lowest terms), you divide
the numerator and denominator both by their greatest common
factor. (That's why you learn 'greatest common factor' before
you learn to simplify fractions.)

The greatest common factor of 36 and 80 is 4 .

Divide the top and bottom of 36/80 by 4, and you'll have the
fraction in lowest terms.

36 and 80 can both be divided by 4.

Which will make you answer 9/20.

-3(-5v-u+6)

Answers

Hey there!

-3(-5v - u + 6)

= -3(-5v) - 3(-u) - 3(6)

= 15v - 3u - 18

= 3u + 15v - 18

Therefore, your answer is: 3u + 15v - 18

Good luck on your assignment and enjoy your day!

~Amphitrite1040:)

I could be wrong however, I'm sure it's: -3x-5= 15v (two negatives become a positive. -3-u becomes 3u. (Two negatives also become a positive), and -3+6 is -3x6= -18. Hence, the answer is: 15v+3u-18.

The measure of an angle is 3/4 of 60 degrees. What is the measure of the complementary angle?

Answers

First we can convert the fraction into a decimal which would be 0.75. Then we continue to multiply 0.75 by 60 which would then give us the answer. 0.75*60=45 degrees We can prove this by dividing 90/2 which equals 45 because 2 complementary angles add up to 90 degrees. 45 degrees is the final answer. Hope this helps!

3/4 x 60/1 = 40 I don't know I'm sorry.
