Answer:

-8

Step-by-step explanation:

The final temperature was -18 °F if it decreased by 5 degrees.

The addition operation in mathematics adds values on each side of the operator.

For example 4 + 2 = 6

The temperature was -13 °F and then dropped 5 degrees.

As per the question, we have data as follows:

The initial temperature = -13 °F

The changed temperature = -5 °F (negative sign indicates temp dropped)

Final temperature = initial temperature + changed temperature

Final temperature = -13 °F + (-5 °F)

Final temperature = -13 °F - 5 °F

Apply the addition operation, and we get

Final temperature = -18 °F

Therefore, the final temperature was -18 °F.

Answer:

88

Step-by-step explanation:

88 ÷ 8 = 11

and 11 - 12 = -1

Answer:

88

Step-by-step explanation:

We can turn this into an algebraic equation. So...

x/8-12=-1  Add 12 to both sides.

    +12 +12

x/8=11       Multiply by 8 on both sides.

*8    *8

x=88

The number is 88.

Answer:

first you have to divide the 144 by 4 to get the answer which is 36

Step-by-step explanation:

144÷4=36

then you take 3 × 36= 108 juice boxes

then you take the number of juice boxes which is 36 and divide it by 36 which is 1 case

the you take 6×36=216

288÷36 = 8 cases

Answer:

-107

Step-by-step explanation:

x4-5^3+ 3^2-2x + 7

2x−109/x−1

1   2   −109

    2

second step

1   2                    -109

                    1 * 2 = 2

    2 (-109) + 2 = -107

Coefficients are 2, and -107

Therefore the quotient is 2 and the remainder is -107

Answer:

the appropriate operation count is 27 times longer than the original one.

Step-by-step explanation:

Given the data in the question;

let us consider the approximate operation count for the system of n₁ equation in n₁ unknowns as; [tex]\frac{2}{3}n[/tex]₁³ Or  

O₁ =  [tex]\frac{2}{3}n[/tex]₁³

so if the value of the unknowns is tripled i.e, n₂ = 3n₁,

the appropriate operation count will be;

O₂  =  [tex]\frac{2}{3}n[/tex]₂³

= [tex]\frac{2}{3}(3n_{1})[/tex]³

= [tex]\frac{2}{3}[/tex] × 27 × n₁³

= 27(  [tex]\frac{2}{3}n[/tex]₁³  )

O₂ = 27(O₁)

Therefore, the appropriate operation count is 27 times longer than the original one.

Answer:

500 grams

Step-by-step explanation:

2.5 kg = 5 loaves

1 loaf = 2.5/5 = 0.5 kg

0.5 kg = 500 grams

Answer:

1. Mean = 55.8

Median = 23

Mode = None

2. Mean = 2.1

Median = 1.4

Mode 0.5

3. Mean = 4.5

Median = 4.5

Mode = 1,4, 5, 8

4. Mean 68

Median 58

Mode = 0

Step-by-step explanation:

Mean = 17 + 25 + 23 + 200 + 14 / 5 = 279/5 = 55.8

Median= Because its odd you put them in order 17, 14, 23, 25, 200 = 23 because it is the middle number. Mode = None

2. Mean = 0.5 + 1.4 + 3.0 + 7.0 + 0.5 +1.8 + 0.5 = 14.7 = 14.7/7 = 2.1

Median = because it is odd you put them in order 0.5, 0.5, 0.5, 1.4, 1.8, 3.0, 7.0 = 1.4 The mode is 0.5 because it repeats three times

3. Mean = 1 + 8 + 5 + 4 + 1 + 8 + 5 + 4 = 36/8 =4.5

Median = Because its even you divide by the two middle numbers = 1, 1, 4,4, 5, 5 , 8 , 8 = 4+5 = 9/2 = 4.5 Mode = 1, 4, 5, and 8 are the numbers that are repeated most often.

Mean = 0+78+99+58+65+0+47+38+227 = 68 Median, Because there is an odd number you get the odd number from the middle. 0, 0, 38, 47, 58, 65, 78, 99, 227 = 58 Mode = 0 because it repeats more often.

Answer:

The length of Louis's basement is 85 feet.

Step-by-step explanation:

The area of the basement, A = 4,335 square feet

The width of the basement is  3/5 its length.

Let length be l.

Width = (3/5)l

The area of the basement is given by :

[tex]A=l\times b\\\\4,335 =l\times \dfrac{3}{5}l\\\\4,335 =\dfrac{3}{5}l^2\\\\l^2=\dfrac{4,335 \times 5}{3}\\\\l=\sqrt{\dfrac{4335\times5}{3}}\\\\l=85\ ft[/tex]

So, the length of Louis's basement is 85 feet.

Answer:

60 but im to surw

Step-by-step explanation:

All i remember is that you have to do A=lwh so it would have to be 4x2x7.5=60

Answer:

first of all the formula

y = mx+c

where m is slope and c is y-intercept.

now substitute the values-

y = 2x - 5

(for the slope here is 2 and the part where the line intercepts y axis is -5

therefore

y = 2x-5

Step-by-step explanation:

Answer:

to the shop : 5/8 of an hour

back home :  3/8 of an hour

Step-by-step explanation:

We use the relationship between distance travelled, speed and time given by the formula:

speed = distance / time

We know that the distance from home to the coffee shop is D (same for trip back)

We also know the two speeds in one direction 9 mph and in the other 15 mph

then we can find the times t1 (to the coffee shop) and back (t2) by using the equations:

D = 9 * t1

D = 15 * t2

1 = t1 + t2

We set the two distances equal to have:

9 * t1 = 15 * t2

then t1 = 15 * t2 / 9 = 5 t2 / 3

and use this to substitute for t1 in the last equation:

t1 + t2 = 5 t2/3 + t2 = 1

8 t2 /3 = 1

then t2 = 3/8 of an hour

and therefore t1 must be 1 - t2 = 5/8 of an hour
