Answer:

-1+5z, -25+20y, 4d+14, 2n-2, 40k+8, 8b+5, -9+22p

Step-by-step explanation:

1) -4+7z+3-2z

-1+5z

2) 15+4(5y-10)

15+20y-40

-25+20y

3) 2d+17-3-2d+4d

4d+14

4) 12n-8-2n+10-4

2n-2

5) 8(2k+1+3k)

16k+8+24k

40k+8

5) 4(2b+2)-3

8b+8-3

8b+5

6) -4+8p-6p-5+20p

-9+22p

Each 5 minutes represent 1 mile. This can be also referred as independent and dependent variables. It takes 5 minutes for 1 mile. Or T=5m (m=minutes) D=1

so 5 x 2 (5 minutes x 2) = 10 minutes and 10 minutes equal to 2 miles, each 5 minutes is another mile. For example, 60 minutes (1 hour) 60 divided by 5 = 12 so in 1 hour (60 mins) equal to 12 miles in total! hope this helps at least a bit! :)

Answer:

B

Step-by-step explanation:

speed is determined by the gradient

car 1 gradient = change in y / change in x =  [tex]\frac{85 - 75}{17 -15} = \frac{10}{2} = 5[/tex]

car 2 gradient = 10

so car 2 is travelling faster than car 1

Answer:

66 2/3

Step-by-step explanation:

The way to solve this is The general volume of a pyramid formula is given as: Volume of a pyramid = 1/3 x base area x height. Where Ab = area of the polygonal base and h = height of the pyramid. Note: The volume of a pyramid varies slightly depending on the polygonal base.

What i did was i first tried to do 17 x 20 x 10 which game 3400 but when i remembered that V=1/3 x base area x height which would be 1/3 x 17 x 20 = 113 1/3 but if the base was 10 it would be 1/3 x 10 x 20 = 66 2/3. so i think the base is 10 and the answer would be 66 2/3

If i am wrong i'm sorry

Answer:

about 10 hrs each id say

Step-by-step explanation:

I just did 5 times two

The time taken to fill the pool if it were working alone is 18 hours.

One of the four fundamental mathematical operations, along with addition, subtraction, and division, is multiplication. Multiply in mathematics refers to the continual addition of sets of identical sizes.

The symbols cross (×), asterisk (*), and dot (·) are used to denote multiplication. You most frequently utilize the cross when writing in your notebooks. In computer languages and algebra, the asterisk and dot are both utilized (higher mathematics).

Given:

When 2 pipes fill a pool together, they can finish in 5 hrs,

One of the pipes fills half the pool then the other takes over to finish filling the pool, it will take them 18 hrs

1 / 2 of pool = 9 hrs as given

full pool = 9 × 2 = 18 hours

Therefore, The time taken to fill the pool if it were working alone is 18 hours.

Step-by-step explanation:

Answer:

If you used π, 157.079632679 yards or 157.08 yards rounded to the hundredths place. If you used 3.14, the answer is 157 yards.

Step-by-step explanation:

The formula to find the perimeter of a circle is P=2×π×r.

Step 1: Find the radius. In this case, the radius is 25 yards as shown in the diagram.

Step 2: Since the formula only includes multiplication, you can multiply any of the factors. For simplicity, multiply your radius by 2 first. In this case, 2×25=50.

Step 3: Multiply your last number with π. In this case, 50×π=157.079632679 or 157.08 rounded the hundredths place. 50×3.14=157.

Step 4: You found the answer! Hope this helps.

Answer:

25.5m

Step-by-step explanation:

square area: 6m*3.5m = 21m

Triangle height: 5m - 3.5m = 1.5m

Triangle area: [tex]\frac{1.5m*6m}{2}[/tex] = 4.5m

Total area: 21m + 4.5m = 25.5m

Answer:

1st 2nd and 3rd box

Step-by-step explanation:

1. It does not form a straight line because the output is not proportional. (it does not follow a pattern)

2. the line is not proportional because it does not follow a pattern or ratio of any kind (2468 is proportional because it follows the pattern of 2)

3. the origin is the coordinates (0,0) and the table has that labeled in the diagram therefore the graph does go through the origin

4. the output is not constant (output is 0149) because it does not show any sort of pattern. therefore the 4th box is incorrect.

Answer:

She will have 19 ¹/₂ batches of purple paint

Step-by-step explanation:

r + b = 1 bp

³/₄ r + ³/₄ b = 1 bp

(³/₄ + ³/₄) * 13 = x bp

⁶/₄ = 1 ¹/₂

1 ¹/₂ * 13 = 13 ¹³/₂ = 19 ¹/₂ batches

VARIABLE KEY:

r = red

b = blue

bp = batches of purple

x = total number of bp

Step-by-step explanation:

Answer:

Steps:

Pc = 120 - (120/100×20)

Pc = 120 - (1.2×20)

Pc = 120 - 24

Pc = 96

P = Pc + (Pc/100×5)

P = 96 + (96/100×5)

P = 96 + (0.96×5)

P = 96 + 4.8

P = $100.80

Answer:

I’m pretty sure the answer would be $100.80

Step-by-step explanation:

1. Take the $120 and multiply by 0.20, which will give you 24 (that’s 20% of 120)

2. Subtract $120-$24= $96

3. There is a 5% sales tax so take 96 and multiply by 0.05 and you get 4.8

3. Add $96+$4.80= $100.80
