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

Answers

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)

Answers

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

118/13= 59/z

what is the answer?? ​

Answers

Z=6.5 because 118/2 is 59 and 13/2 is 6.5 hope I got it right and it helped

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!

Answers

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
