Answer:
6.8 km/hr
Step-by-step explanation:
If Sara ran 34 km in 300 minutes, then, in one hour, she would run
=> 34 : 300
=> ? : 60
=> 300 / 5 : 34 / 5
=> 60 : 6.8
So, if she travels 6.8 km in 60 minutes, her speed is 6.8 km/hr

Step-by-step explanation:
First combine the x³s.
-4x³ + 8x³ = 4x³
Then, combine the x²s.
2x² + 6x² = 8x²
Now, combine the remaining values.
9 + 1 = 10
Finally put it together.
4x³ + 8x² + 10
Hope that helps and maybe earns a brainliest :)

Answer:
Step-by-step explanation:
The common difference, d, is 3, because the number of squares goes up by 3 each time.
d = 3
Number of squares in nth figure is:
a(n) = 4 + d(n - 1)
4 is the initial number of squares, d is how many it goes up each time, and we take n-1 because you need to account for the initial number of squares.
a(n) = 4 + d(n - 1)
For n = 200
a(n) = 4 + d(n - 1)
a(200) = 4 + 3(200-1)
a(200) = 4 + 3(199)
a(200) = 4 + 597
a(200) = 601

A few boats were traveling upstream and downstream. A satellite recorded the movements of several boats. A motor boat traveled -3.4 miles for every hour in 0.75 hours. How much progress?
Answer:
-2.55 in .75 miles
Step-by-step explanation:
the unit rate is -3.4
so every time it goes up or down it will be the number of hours times -3.4
.75×-3.4=-2.55

118/13= 59/z
what is the answer??
Answer:
[tex]z = 6.5[/tex]
Step-by-step explanation:
If we take a look at the problem, we are solving for z.
[tex]\frac{118}{13} = \frac{59}{z}[/tex]
To figure it out, we have to cross multiply. So we take [tex]118 * z[/tex] and [tex]59 * 13[/tex], which gives us [tex]118z =767\\[/tex]. Next, we divide both sides with 118.
[tex]\frac{118}{118}z=\frac{767}{118}\\ \\z = 6.5[/tex]
Then, we get 6.5 as our answer!
Hope this helped!

Raul is performing an experiment. He pours water into a glass and measures the temperature of the water at 72.3°F. Then he adds a few ice cubes to the glass of water. He measures the temperature of the water again and finds that it has changed by -39.1°F.
Simplify the expression in (-30) + 70 + (-9) + 2 +(-0.1) + 0.3 = 2 + (-9) + 70 + (-0.1) + 0.3 + 70
Answer:
When you add the left side of the equation, you get 33.2 because 70-30 is 40, 40+2 is 42, 42-9 is 33, 33+0.3 is 33.03, 33.3-0.1 is 33.2.
Step-by-step explanation:
Answer:
[70 + (-30)] + [2 +(-9)] + [0.3 + (-0.1)]
=
40 + (-7) + 0.2
=
33 + 0.2
=
33.2°F
The temperature of the water dropped to 33.2°F after Raul added the ice cubes.

Use the Distributive Property to simplify the expression.
1/4(8+x+4)
Answer:
3=1/4x
Step-by-step explanation:
1/4(8+x+4)
=2+1/4x+1
=3+1/4x
The expression after simplification will be 3+x/4
What is Distributive Property?According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Given an expression, 1/4(8+x+4)
Solving by using Distributive Property,
= 1/4 × 8 + 1/4 × x +1/4 × 4
= 2 + x/4 + 1
= 3 + x/4
Hence, the expression after simplification will be 3+x/4
