Step-by-step explanation:

43 hours per week i think

Answer:

40 hours per week (40:1)

Step-by-step explanation:

559 / 13 = 39.93

39.93 rounded to the nearest whole number is 40.

Answer: Yes, because the amount of money you save for every beverage bought is constant, and if you buy 0 beverages, you’ll save $0. That means it the situation is graphed, the line produced will be linear and crosses through the origin, which are the requirements for a proportional relationship.

Zarab pay for all candies = 5x

Zarab pay for all cakes = 20 y

Total cost = 5x + 20y

Money spent = 5x + 20y

= 5 × 10 + 20 × 5

= 50 + 100

= $150

Answer:

She baked 640 cookies at first.

Step-by-step explanation:

Let cookies be x and muffins be y,

Let cookies remaining be z and remaining muffins be a

x = 264 + y

now,

x - 3/8 of x = z

x - 3x/8 = z

or, (8x-3x)/8 = z

so, z = 5x/8

Now,

y - y/2 = a

or, (2y-y)/2 = a

so, a = y/2

Now,

z + a = 588

or, 5x/8 + y/2 = 588

as we know x = 264 + y,

or, 5(264 + y)/8 + y/2 = 588

or, (1320 + 5y)/ 8 + y/2 = 588

or, (2640 + 10y + 8y)/16 = 588

or, 2640 + 18y = 9408

or, 18y = 9408 - 2640

or, 18y = 6768

so, y = 6768/18

so, y = 376

now,

x = 264 + y

or, x = 264 + 376

so, x = 640

Answer: 7.5

Step-by-step explanation:

Area of the bottom left triangle = 4x3/2 = 6

Bottom right = 6x3/2 = 9

Top right = 3x4/2 = 6

Top left = 6x3/2 = 9

6+9+6+9 = 30

Each square unit is 4

So the answer should be 30/4 = 7.5

Hope this is correct

Answer:

30 ounces

Step-by-step explanation:

1 chain = 10 pounds per foot

3inches = ?

therefore

? = 30 ounces

[tex] \frac{r}{3} - 2 = 2 \\ \\ \frac{r}{3} = 2 + 2 \\ \\ \frac{r}{3} = 4 \\ \\ r = 4 \times 3 \\ \\ r = 12.[/tex]

The value of r is 12 .

Answer:

A= 0.5 x (a+b) x h

124 = 0.5 x (12+19) x h

124 = 15.5 x h

÷15.5

h = 8cm

0.5x(12+19) x 8 does gives 124

Thus, height is 8cm.

Hope this helps!

Answer:

20

Step-by-step explanation:

All you do add because it is with even numbers

Answer:

1. Undefined

2. Negative

3. Zero

4. Positive

Step-by-step explanation:

1. Undefined, the line moves in both directions vertically. It's impossible to tell what the slope is.

2. Negative, the line is decreasing at a constant rate, the slope is negative.

3. Zero, the line doesn't increase or decrease, therefore the slope is 0. (No changes)

4. Positive, the line is increasing at a large rate, the slope is positive.

Answer:

25-50 correct

Step-by-step explanation:

Answer:

33.49 cubic inches

Step-by-step explanation:

the volume of a sphere is represented by (4/3)pi(r)^3

pi is 3.14 and r is 2

so 4/3(3.14)(2^3)

2^3 is also 8

4/3(3.14)(8)

the final answer is 33.4933333

OR when rounded it is 33.49

Statement:

The radius of the sphere is 2 inches.

To find out:

The volume of the sphere.

Solution:

[tex] = \frac{4}{3} \times 3.14 \times {(2)}^{3} \: \: cubic \: \: inches \\ = \frac{4}{3} \times 3.14 \times 8 \: \: cubic \: \: inches \\ = 33.49 \: \: cubic \: \: inches[/tex]

Answer:

The volume of the sphere is 33.49 cubic inches.

MALPI THE NUBERS

Answer:

The two numbers are 20 and 60

Step-by-step explanation:

Two numbers: x and y

x + y = 80

x - y = 40

x = y + 40

Substitute x

y + 40 + y = 80

2y + 40 = 80

2y = 40

y = 20

Substitute y, so x = 60

Answer:

[tex]x + 6 > 4 \\ x > 4 - 6 \\ x > - 2 \\ and \\ 3x + 5 < 5 \\ 3x < 5 - 5 \\ 3x < 0 \\ \frac{3x}{3} < \frac{0}{3} \\ x < 0 \\ therefore \\ - 2 < x < 0 [/tex]

Answer:

75.36 cm

Step-by-step explanation:

We need to find the circumference of the pipe.

Circumference of a circle = 2[tex]\pi[/tex]r   (where r is the radius)

Given:

⇒ circumference = 2 x 3.14 x 12 = 75.36 cm

Answer:

-(1 - 2a)^2

Step-by-step explanation:

-1 + 4a - 4a^2

= -[1^2 - 2*1*(2a) + (2a)^2]

= -(1 - 2a)^2

Answer:

Step-by-step explanation:

Begin by taking out the minus

-(4a^2 - 4a + 1)     The answer is the square root of the 1st and 3rd terms.

√4a^2 = 2a

√1 = 1                    Since middle term is minus, one of 2a or 1 must also be minus

Usually the one is made minus.

That leaves you with a perfect square

- (2a - 1)^2   There are more ways than 1 to write this, but I think this is the clearest answer

Answer:

4

Step-by-step explanation:

yes 1x is the same a x Technically the 1 front of the x is called implied so it's simply written as x say x=4

Answer:

5/9

Step-by-step explanation:

I assume the second x is a times.

X*15=8 1/3

Divide both sides by 15

x= 5/9 or .555 repeating forever

Answer: 310

Step-by-step explanation:

Multiplying a value by 1/10 is the same as dividing by 10.

Therefore, 3100* 1/10 = 3100/10

3100/10 = 310.

Hey there!

3,100 × 1/10

= 3,100/1 × 1/10

= 3,100(1) / 1(10)

= 3,100 / 10

= 3,100 ÷ 10 / 10 ÷ 10

= 310 / 1

= 310 ÷ 1

= 310

Therefore, your answer is: 310

Good luck on your assignment & enjoy your day!

Answer:

A is the correct answer

Answer:

11.5 hours

Step-by-step explanation:

It would take Seith x hours to paint the room by himself, then Ted needs x + 1 hour.

During 1 hour, Seith can do 1/x of the work, Ted can do 1/(x+1) of the work, then we have

1/x + 1/(x + 1) = 1/6

(2x + 1)/[x(x+1)] = 1/6

x(x+1)=6(2x+1)

x^2 + x = 12x + 6

x^2 - 11x - 6 = 0

[tex]x=\frac{11+\sqrt{145}}{2}= 11.5 hours[/tex]

Answer:

LCM of 7/10- 70

LCM of 5/6- 30

Step-by-step explanation:

Solution:

To find the Least common denominator (LCD) of 7/10 and 5/6, we need to find the Least common multiple of 10 and 6.

I found the LCM through division method. Refer to image attached~

We can tell that:

Now, let's multiply the denominators and the numerators such that 30 is the denominator in both fractions.

The fractions are:

Answer:

Part A: 9.75x > 195

Part B: x > 20

Step-by-step explanation:

Let's say Mark works for x hours. For each hour he works, 9.75 dollars are added to Mark's salary. Therefore, for 1 hour, he gets $9.75, for 2 hours, he gets $9.75 + $9.75 = $9.75 * 2 = $19.50, and for x hours, he gets $9.75 * x as his salary.

We want his salary to be more than $195, so we have $9.75 * x (his salary) > $195, which can be written as 9.75x > 195

divide both sides by 9.75 to solve for x

x > 20
