A school bought pens, each costing $1, and pencils, each costing $0.5. The cost of the whole purchase was $220. How many pens and pencils were purchased if there were 80 more pencils than pens?

Answers

Answer:

120 pens and 200 pencils.

Explanation:

You can set a system of two equations.

1. Variables

x: number of pensy: number of pencils

2. Cost

each pen costs $1, then x pens costs: xeach pencil costs $0.5, then y pencil costs: 0.5y

Then, the total cost is: x + 0.5y

The cost of the whole purchase was $ 220, then the first equation is:

          x + 0.5y = 220 ↔ equation (1)

3. There were 80 more pencils than pens

Then:

  pencils  =      80   +   pens

       ↓                               ↓

       y        =      80   +      x        ↔ equation (2)

4. Solve the system

i) Substitute the equation (2) into the equation (1):

x + 0.5(80 + x) = 220

ii) Solve

x + 40 + 0.5x = 2201.5x = 180x = 180/1.5x = 120 pens

iii) Substitute x = 120 into the equation (2)

y = 80 + 120y = 200 pencils

Solution: 120 pens and 200 pencils ← answer

This composite figure has been divided into three rectangles. What is the area of this composite figure

Answers

Given:

A composite shape consisting of three rectangles with different lengths and widths.

To find:

The area of the composite shape.

Solution:

To find the area of the composite shape we must add the areas of all the three rectangles.

The upper rectangle has a length of 8 inches and a width of 4 inches.

The area of a rectangle [tex]= (l)(w).[/tex]

The area of the upper rectangle [tex]=(8)(4)=32[/tex] in².

The middle rectangle has a length of [tex]8-4=4[/tex] inches and a width of [tex]10-4-1.5=4.5[/tex] inches.

The area of the middle rectangle [tex]=(4)(4.5) = 18[/tex] in².

The lower rectangle has a length of 8 inches and a width of 1.5 inches.

The area of the lower rectangle [tex]= (8)(1.5)=12[/tex] in².

The area of the composite shape [tex]= 32+18+12 = 62[/tex] in².

The composite shape has an area of 62 in² which is option 3.

0.75p=0.4+100

Answers

Answer:

p=133.866667

Step-by-step explanation:

Let's solve your equation step-by-step.

0.75p=0.4+100

Step 1: Simplify both sides of the equation.

0.75p=0.4+100

0.75p=(0.4+100)(Combine Like Terms)

0.75p=100.4

0.75p=100.4

Step 2: Divide both sides by 0.75.

0.75p/0.75 = 100.4/0.75

p=133.866667

Ashley is making cookies for her Easter party. Each batch of cookies mix need 0.4 cups of sugar and each batch can make 16 cookies. If Ashley is making 4 batches of cookies, how much sugar does she need?

Answers

Answer:

1.6 cups

Step-by-step explanation:

Each batch needs 0.4 cups of sugar, and she is making 4 batches. Therefore, we can multiply 0.4 times 4 to find how much sugar is needed.

0.4*4=1.6

So, she needs 1.6 cups of sugar for 4 batches

Answer:

1.6 cups of sugar for four batches of cookies

a trucker drove 500 miles in h hours. If the trucker averaged 60 mph, which linear equation could be used to find the number of hours that the trucker drove?

Answers

Step-by-step explanation:

Given that,

Distance covered by a trucker, d = 500 miles

Average speed of the trucker, v = 600 mph

A trucker drove 500 miles in h hours. We need to write the linear equation used to find the number of hours that the trucker drove. Average speed is given by :

[tex]v=\dfrac{d}{t}[/tex]

t is time in hours

[tex]t=\dfrac{d}{v}\\\\t=\dfrac{500\ miles}{60\ mph}[/tex]

If t is h hours,

[tex]h=\dfrac{500\ miles}{60\ mph}\\\\500=60h[/tex]

On solving, h = 5 hours.

Hence, this is the required solution.

and 17 are custard-filled. You randomly select one donut, eat it, and select another donut. Find the probability of selecting two custard-filled donuts in a row.
(Type an integer or a simplified fraction.)

Answers

Answer:

34/69

Step-by-step explanation:

2 are jelly-filled

5 are lemon-filled

17 are custard-filled

Total: 24

First drawing:

There are 24 donuts in total, 17 of which are custard filled.

p1(custard filled) = 17/24

Second drawing:

There are now a total of 23 donuts, 16 of which are custard filled.

p2(custard) = 16/23

The two drawings are independent events, so the overall probability is the product of the individual probabilities.

Overall probability of drawing two custard filled donuts:

p(2 custard filled) = p1 * p2 = 17/24 * 16/23 = 17/3 * 2/23 = 34/69

Use 3.14 for LaTeX: \piπ.

Round to the nearest hundredth.

Pro tip: don't count the surfaces that are not exposed.

Answers

Given:

The radius of given fig = 2.2 unit

The height of the cylindrical part = 8.7 unit

The slant height of the cone = 10.2 unit

To find the total surface area of the given figure.

Formula

The given figure consists of a cylinder and a cone.

So, the surface area of the fig

[tex]SA = \pi r l+2\pi r h+\pi r^{2}[/tex]

Where, r be the radius

h be the height

l be the slant height

Now,

Putting,

r=2.2, h = 8.7, l=10.2 and π=3.14 we get,

[tex]SA = (3.14)(2.2)(10.2)+2(3.14)(2.2)(8.7)+(3.14)(2.2^{2} )[/tex] sq unit

or, [tex]SA = 70.4616+120.1992+15.1976[/tex] sq unit

or, [tex]SA = 205.8584[/tex] sq unit

or, [tex]SA = 205.86[/tex] sq unit

Hence,

The total surface area of the given figure is 205.86 sq unit.

the y-intercept is [tex](0,-1.5)[/tex]

Step-by-step explanation:

(the website i used to graph it is called desmos)

After you graph the line, the y-intercept is the point on the line where it passes through the y-axis. On this line, that point is [tex](0,-1.5)[/tex]

To find the slope, an easy way would be to use "rise over run"

Find two points on the line and plug them into this equation: [tex]\frac{y_{1} -y_{2} }{x_{1} -x_{2} }[/tex], for this i used the points [tex](5,-4)[/tex] and [tex](7,-5)[/tex]

I need assistance thank u

Answers

Answer: I think the table has the greater rate of change because to find the greater rate of change we have to find the rate of change for both function. So, for this we have to find two points for both and then using the slope formula we have to solve for it.

for the first one: (4,6)(6,9)

9-6/6-4

3/2

For the second function: (4,5)(5,10)

10-5/5-4

5/1

5

so as we see that 3/2 is not greater than 5 so the function 3 has the greater one.

I don't know how to solve the first one. I am sorry but hope this helps you!

In ΔLMN, m∠L = 108°, m∠M = 25°, and ℓ = 12. What is m?

Answers

Answer:

m = 5.33

Step-by-step explanation:

First we need to calculate angle N.

Sum of angles in a triangle is 180°

∠L + ∠M + ∠N = 180°

108°+25°+∠N = 180°

∠N = 180°-(108°+25°}

∠N = 180°-133°

∠N = 47°

Given side l = 12, to get m, we will use the sine rule.

l/sinL = m/sinM = n/sinN

12/sin108° = m/sin25°

m × sin108°= 12sin25°

m = 12sin25/sin108°

m = 5.071/0.951

m = 5.33
