5A. 80

6A. 84

8. 80

12. 130

17. 800

2. 10.5 cm

3. $102

4. 33 cars

5B. Gas: $55.44 Electricity: $76.56

6B. 85%, $17

Step-by-step explanation:

:) I think these are correct! They are in order from each page!

5A: 80*20%=16

6A: 84*50%=42

8: 80*75%=60

12: 130*40%=52

17: The printer costs $160, and 800*20%=160

2: 25% of 84 is 21 so there is 63 cm left. Divide by 6 and you get 10.5

3: 25% of 136 is 34 so he has 136-34 left, or 102

4: 17.5% of 240 is 42 so there are 198 other colors. Divide by 6 you get 33

5B: 42% of 132 is 55.44 if you subtract you get 76.56

6B: 100%-15%=85% and 85% of 20 is 17

Answer:

a. 2x+3z

b. 7xy

c.   [tex]\frac{3ab}{2c}[/tex]

d. 10z-6q

e. Subtract xy from the sum of p and q.

f.  Divide the sum of 3 and y by 5.

g. Subtract 2c from the square root of b.

h. 3x ... 4x ...

i. 3y ... y+5 ... 5y+5

j. length ... 3 ... breadth ... 8b ... 3b²

Step-by-step explanation:

Sum means addition. 2x + 3z

Product means multiplication. 7y × x = 7xy

Divide 3ab by 2c. 3ab ÷ 2c = [tex]\frac{3ab}{2c}[/tex]

Subtract 6q from 10z.  10z-6q

(p+q)-xy : Subtract xy from the sum of p and q.

(3+y)/5: Divide the sum of 3 and y by 5.

[tex]\sqrt{b}[/tex]- 2c: Subtract 2c from the square root of b.

Let the number of boys be x. Girls are three times more so 3 × x = 3x. The total would be 3x + x = 4x.

Let Nora's age be y. Father is three times more so 3 × y = 3y. Brother is 5 more so would be y+5. The total would be y + 3y + y + 5 = 5y+5

3b is three times more than b, the breadth. Thus, the length is three times more than the breadth since it is 3b. The perimeter would be 3b + b + 3b + b = 8b. The area would be 3b × b = 3b²

Answer:

[tex] 17 + BD = 73 [/tex] (substitution)

[tex] BD = 73 - 17 [/tex] (subtraction property of equality)

Hopefully this helps

Step-by-step explanation:

By using the Divergence Theorem, the flux equals

∫∫∫ div F dV

= ∫∫∫ ((-2x - 4y) + (-6z) + 12) dV

= ∫(z = 0 to c) ∫(y = 0 to b) ∫(x = 0 to a) (12 - 2x - 4y - 6z) dz dy dx

= ∫(z = 0 to c) ∫(y = 0 to b) (12a - a^2 - 4ay - 6az) dy dx

= ∫(z = 0 to c) (12ab - a^2 b - 2ab^2 - 6abz) dx

= 12abc - a^2 bc - 2ab^2 c - 3abc^2.

So, we need to find the maximum value of

f(a,b,c) = 12abc - a^2 bc - 2ab^2 c - 3abc^2, with a,b,c > 0.

First, we find the critical points of f.

f_a = 12bc - 2abc - 2b^2 c - 3bc^2 = bc(12 - 2a - 2b - 3c)

f_b = 12ac - a^2 c - 4abc - 3ac^2 = ac(12 - a - 4b - 3c)

f_c = 12ab - a^2 b - 2ab^2 - 6abc = ab (12 - a - 2b - 6c).

Setting these equal to 0 (and remembering that a, b, c > 0):

12 - 2a - 2b - 3c = 0

12 - a - 4b - 3c = 0

12 - a - 2b - 6c = 0

Solving this system yields a = 3, b = 3/2, c = 1.

By the Second Derivative Test or otherwise, this can easily be checked to yield the maximum flux.

This maximal flux equals f(3, 3/2, 1) = 27/2

In this exercise we have to use the knowledge of the divergence theorem, so we can say that the integral will be given by:

[tex]f(3, 3/2, 1) = 27/2[/tex]

By using the Divergence Theorem, the flux equals:

[tex]= \int\limits \int\limits \int\limits{ ((-2x - 4y) + (-6z) + 12) dV}\\= 12abc - a^2 bc - 2ab^2 c - 3abc^2[/tex]

So, we need to find the maximum value of:

[tex]f(a,b,c) = 12abc - a^2 bc - 2ab^2 c - 3abc^2[/tex]

First, we find the critical points:

[tex]f_a = 12bc - 2abc - 2b^2 c - 3bc^2 = bc(12 - 2a - 2b - 3c)f_b = 12ac - a^2 c - 4abc - 3ac^2 = ac(12 - a - 4b - 3c)f_c = 12ab - a^2 b - 2ab^2 - 6abc = ab (12 - a - 2b - 6c).[/tex]

Setting these equal to:

[tex]12 - 2a - 2b - 3c = 012 - a - 4b - 3c = 012 - a - 2b - 6c = 0[/tex]

Answer:

$6.96

Step-by-step explanation:

0.25 pound = $1.74

for 1 pound multiply by 4, since there are four 0.25 (quarters) to 1 pound.

1.74*4 = 6.96

Answer:

I think it is 6.94

Step-by-step explanation:

0.25 is 1/4 of a dollar so we should multiply 1.74 by 4 and we get 6.94 dollars for  1 pound of tuna salad

Equality Properties

Step-by-step explanation:

Step 1: Define

x - 9 > -15

Step 2: Solve for x

Here we see that any number greater than -6 would work as a solution to the inequality.

The solution to the inequality x - 9 > -15 is x > -6.

To solve the inequality x - 9 > -15, we can follow these steps:

Step 1: Add 9 to both sides of the inequality to isolate the variable term:

x - 9 + 9 > -15 + 9

x > -15 + 9

Simplifying:

x > -6

Therefore, the solution to the inequality x - 9 > -15 is x > -6.

Answer:

[tex]\frac{2.54cm}{1in}[/tex]

Step-by-step explanation:

Given

[tex]3.6m = 3.6m * \frac{100cm}{1m} * \frac{2.54cm}{1in} * \frac{1ft}{12in} * \frac{1yd}{3ft}[/tex]

Required

Which ratio is incorrect

Each ratio is a conversion of 1 unit to the other.

Taking them one at a time.

The first is [tex]\frac{100cm}{1m}[/tex]

[tex]1m = 100cm[/tex] --- The ratio is correct

The next is: [tex]\frac{2.54cm}{1in}[/tex]

[tex]2.54\ cm = 1\ in[/tex]

The conversion is correct; however the ratio is incorrect.

This is so because, the first ratio ([tex]\frac{100cm}{1m}[/tex]) has centimetre as the numerator

The next should have centimetre has its denominator in order to cancel out the units.

So, the correct ratio is:

[tex]\frac{1\ in}{2.54\ cm}[/tex]

Answer:

147.75 milliliters

Step-by-step explanation:

Find 5/8 of 236.4

So 147.75

So Harold’s kitten drinks 147.75 milliliters Of water everyday.

The measurement is closest to the number of milliliters of water Harold's kitten drinks every day is 147.75 milliliters.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Harold's kitten drinks 5/8 cup of water every day.

One cup is approximately equal to 236.4 milliliters.

Now, 5/8 ×236.4

= 5×29.55

= 147.75 milliliters

Therefore, the measurement is closest to the number of milliliters of water Harold's kitten drinks every day is 147.75 milliliters.

Answer:

You got it wrong because you didn't distribute the 7 to the 3j.

Step-by-step explanation:

The answer should be 21j +70.

Answer:

In your original answer, you did not distribute the 7 to the 3j

Step-by-step explanation:

The distributive property basically states that the sum of any variables multiplied by a factor is equal to the sum of each product of every individual variable and the factor.

In short,

a(b+c) = ab + ac

or

x(y + w + z) = xy + xw + xz

or

9m + 9n = 9 (m+n)

Therefore, in order to solve 7(3j + 10)

you must multiply 7 by 3j and 7 by 10

(7 * 3j) + (7 * 10) = 21j + 70

Since 70 does not have the same terms as 21j (70 does not have j),

21j + 70 is in its most simplified form.

In your original answer, you didn't multiply the 3j by 7.

Answer:

Divide the number of miles traveled by the travel time in hours.  That will give you the average speed in miles per hour.

the first will equal 25 miles/hour

when dividing 125m/5h

when downhill it traveled faster at a rate of 35MPH

okay we'll need to sampi the answer

B for boat

C for current

B-c = d/time Uphill will equal = 125/5

so 25

B= 25 - c

d/time downhill = 175/5H = 35mph

25 -c -c =35

this brings it down to 10mph

-5c = 10mphs

which will equal

c= -5 = 5mphs
