A dripping tap wastes 11,250 ml of water in 9 hours. If it drips equal quantity in each hour ,how much water will be wasted in a
EastWind [94]

Answer: In 1 hour , it will waste = 1.25ml

Step-by-step explanation:

Volume of water  wasted by the tap in 9 Hours = 11,250 ml

Since  it drips in equal quantity,

In 1 hr , it will drip=  1 x 11,250 / 9 = 1,250 ml

But  1000 ml = 1 Liter

1250 ml = 1250ml x 1Liter / 1000ml= 1.25L

In Circle M, points A, B, and C are located on the circle such that measure angle CBM equals to 34 degrees. What represents angl
Bess [88]

Answer:

Angle CAB=56 degrees

Step-by-step explanation:

See the attached image for the diagram.

In triangle BMC

|BM|=|MC| (Radii of a Circle)

Therefore, triangle BMC is an Isosceles Triangle; and

\angle CBM=\angle BCM=34^\circ

\angle CBM+\angle BCM+\angle BMC=180^\circ$ (sum of \angle s$ in a triangle)\\34^\circ+34^\circ+\angle BMC=180^\circ\\\angle BMC=180^\circ-68^\circ=112^\circ

Next,

\angle BMC=2\angle CAB $(Angle at center is twice angle at circumference)\\112^\circ=2\angle CAB\\\angle CAB=112^\circ \div 2\\\angle CAB=56^\circ

The table shows the total cost for different numbers of jackets. Number of jackets 2 5 7 Total cost ($) 46. 50 116. 25 162. 75 W
Bond [772]

The cost price of 1 jacket is $23.25 and the cost price of 3 jackets is $69.75.

<h3>What is the cost price?</h3>

Cost price is the total amount of money to produce a given product or provide a given service.

Given cost prices for jackets are,

Jackets Cost Price

2         46.5

5         116. 25

7         162. 75

We need to calculate the cost price of 3 jackets. First, we need to find out the cost price of one jacket.

2 \; \rm Jackets =\$ 46.50

1 \;\rm Jacket = \dfrac {\$46.50}{2}

1 \;\rm Jacket = \$ 23.25

Now the cost price of 3 jackets is given as,

3\;\rm Jackets = \$23.25 \times 3

3\;\rm Jackets = \$69.75

Hence we can conclude that the cost price of 3 jackets is $69.75.

To know more about the cost price, follow the link given below.

17(w-4) +3w -27 <br><br><br> Helpppo
Simora [160]

Answer:

w = 19/4

Step-by-step explanation:

Solve for w:

-27 + 17 (w - 4) + 3 w = 0

17 (w - 4) = 17 w - 68:

17 w - 68 + 3 w - 27 = 0

Grouping like terms, 17 w + 3 w - 68 - 27 = (17 w + 3 w) + (-27 - 68):

(17 w + 3 w) + (-27 - 68) = 0

17 w + 3 w = 20 w:

20 w + (-27 - 68) = 0

-27 - 68 = -95:

20 w + -95 = 0

Add 95 to both sides:

20 w + (95 - 95) = 95

95 - 95 = 0:

20 w = 95

Divide both sides of 20 w = 95 by 20:

(20 w)/20 = 95/20

20/20 = 1:

w = 95/20

The gcd of 95 and 20 is 5, so 95/20 = (5×19)/(5×4) = 5/5×19/4 = 19/4:

Answer: w = 19/4
