- 12x + 7 = 79

- 12x = 79 - 7

- 12x = 72

x =  \frac{ \:  \: \:  72}{-12}

x =  - 6

Let us check whether we have found out the correct value of x or not by placing -6 in the place of x .

<h3>Which means :-</h3>

= -12 × -6 + 7 = 79

= 72 + 7 = 79

<h3>LHS = RHS</h3>

Therefore , 12 × -6 + 7 = 79 , ( x = - 6 ) .

Find the volume of the composite figure. Round your answer to the nearest hundredth
pishuonlain [190]

Answer:

The volume of the figure is 590.71 mm³

Step-by-step explanation:

To solve this problem we have to find the volume of the cylinder and the volume of the rectangular prism and add them

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 3.65mm

π = 3.14

r = radius = 3.2mm

v = (π * r²) * h

we replace the unknowns with the values we know

v = (3.14 * (3.2mm)²) * 3.65mm

v = (3.14 * 10.24mm²) * 3.65mm

v = 32.1536² * 3.65mm

v = 117.36mm³

To calculate the volume of a rectangular prism we have to use the following formula:

v = volume

w = width  = 14.23mm

l = length  = 10.08mm

h = height  = 3.3mm

v = w * h * l

we replace the values that ​​we know        

v = 14.23mm * 10.08mm * 3.3mm

v = 473.347mm³

we add the volumes

v = 117.36mm³ + 473.347mm³

v = 590.707

round to the neares hundredth

v = 590.707 mm³ = 590.71 mm³

The volume of the figure is 590.71 mm³

Two hoses from two different taps are used to fill a fishpond. The first hose alone
Paraphin [41]

Answer:  12 minutes

Step-by-step explanation:

Two rates for hoses A and B.  FP is the Fish Pond.

A = 20 min/FP   or (1/20)FP/min

B = 30 min/FP   or (1/30)FP/min

The time in minutes, X,  to fill  one FP:

                     1FP = X*((1/20)FP/min) + X*((1/30)FP/min)  

                     1FP = X*(1/20+1/30)FP/min

                     1FP = X*(2.5/30)FP/min

                      X = 12 minutes
