1. What is one fourth of 116?




2. The deli made 105 bacon egg and cheese sandwiches and 123 turkey sandwiches.
Once the day was over, the deli workers noticed they sold one half of their sandwiches,
How many sandwiches did they sell?

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: 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:

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:

900 batteries

Step-by-step explanation:

First we must find how many batteries does 1 calculator need

we can do this by dividing 160 by 40

which will give us 4 batteries per calculator

then we multiply the amount of calculators we have with 4

225×4 = 900 so we need 900 batteries

[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:

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.

Hope you could understand.

Answer:

yes they are all functions

Step-by-step explanation:

Despite f(x) being the classic way to write a function,

a function has:

A function relates each element of a set with exactly one element of another (possibly the same) set.  

One-to-one and many-to-one are functions, but one-to-many is not a function.

You can also carry out the Vertical Line Test on a graph.  If the vertical line only crosses the curve once, it is a function.  If it crosses more than once it is still a valid curve, but is not a function.

Yes they all are functions

Functions should include

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:

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

Put y = 2x - 7 into a graphing website and it'll show you (0, -7), (1, -5).

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.

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:

24/5

Step-by-step explanation:

1 1/5 is equal to 6/5. 4 times 6/5 is first 4 times 6 which is 24 and then /5. So the answer is 24/5

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

Sum of angles of triangle = 180°

Answer:

120 children and 388 adults bought tickets for the swimming pool. Explanation: Create two simultanous equations:.

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

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.
