Answer: Option 'B' is correct.

Step-by-step explanation:

Since we have given that

Cost of 5 - pound box of detergent = $3.50

Cost of 15 - pound box of detergent = $10.00

Number of loads can wash 5-pound box of detergent = 20

Number of loads can wash 15-pound box of detergent = 20\times 3=60

For 60 loads to be washed in 15 pound box of detergent costs $10.00

For 60 loads to be washed in 5 pound box of detergent costs

3.50\times 3\\\\=\$10.50

So, total saving while using 15 pound box of detergent is given by

10.50-10.00\\\\=\$0.50

So, total saving per load would be

\dfrac{0.50}{60}=\$0.008=0.8\ cents

Hence, option 'B' is correct.

Answer. Option  B. 0.8 cents.


Solution:

With a 5-pound box of detergent will wash 20 loads of laundry, then with a 15-pound box (5*3) of detergent will wash 20*3=60 loads of laundry, and you would pay $10.00.

To wash 60 loads of laundry with 5-pound box, you would need three 5-pound box, and you would pay $3.50*3=$10.50.


Then you would save in total $10.50-$10.00=$0.50

And per load, you would save: $0.50/60=$0.008=0.008*100 cents=0.8 cents

Solve the following proportion Start Fraction x over 2 End Fraction equals Start Fraction 8 over 9 End Fraction (1 point) 144 0.
daser333 [38]

Answer:

1.78

Step-by-step explanation:

\frac{x}{2} = \frac{8}{9}

To solve for x  we need to cross multiply it

We have = sign inbetween the fractions so we cross multiply it

9*x = 2* 8

9x = 16

Now we divide by 9 on both sides

x= \frac{16}{9}

so x= 1.7777777778

When we round to two decimal places then

x= 1.78

The general form of the equation of a circle is 7x2 + 7y2 − 28x + 42y − 35 = 0. The equation of this circle in standard form is
marta [7]
7 x² + 7 y² - 28 x + 42 y - 35 = 0  /: 7
x² + y² - 4 x + 6 y - 5 = 0
( x² - 4 x + 4 ) + ( y² + 6 y + 9 ) - 4  - 9 - 5 = 0
The equation in the standard form is:
( x - 2 )² + ( y + 3 )² = 18
The center is at the point ( 2, - 3 ).
Its radius is: √18 = 3√2 units.

Which algebraic expression has like terms?
iris [78.8K]

Answer:

Answer:

safe speed for the larger radius track u= √2 v

Explanation:

The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.

Also given that r_1= smaller radius

r_2= larger radius curve

r_2= 2r_1..............i

let u be the speed of larger radius curve

now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=

r

mv

=

r

mu

................ii

form i and ii we can write

v^2= \frac{1}{2} u^2v

=

u

⇒u= √2 v

therefore, safe speed for the larger radius track u= √2 v
