Answer:

Let s be the height of the tree's shadow.

We set up and solve this proportion:

5/2 = 27/s

5s = 54

s = 10.8 feet

The length of the tree's shadow is 10.8 feet.

D) In y = 8x the value of y is 8 times the value of x, and in y = x + 8

the value of y is 8 more than the value of x.

Answer:

Step-by-step explanation:

The quantities given are are in ounces for some and pounds for others

Convert everything to a common unit

1 pound = 16 ounces

Easier to convert all pounds to ounces since you will be working with whole numbers.

Solving by converting all pound units to ounces

1.5 pounds of turkey = 1.5 x 16 = 24 ounces of turkey

Total meat available for sandwiches
= 8 ounces of  roast beef + 16 ounces of ham + 24 ounces of turkey

= 48 ounces

It takes 0.25 pounds of meat to make one sandwich

0.25 pounds = 0.25 x 16 = 4 ounces

Since it takes 4 ounces of meat to make a single sandwich and there are 48 ounces of meat available,

Total number of sandwiches = 48/4 = 12 sandwiches

What if we converted ounces to pounds and solved?
8 ounces = 8/16 pounds = 0.5 pounds

16 ounces = 1 pound

Total meat = 0.5 + 1 + 1.5 = 3 pounds

It takes 0.25 pounds of meat to make a sandwich

Therefore total number of sandwiches = 3/0.25 = 12 (same answer)

Answer:

7 juniors and 2 coins

Step-by-step explanation:

25% is equal to 25/100 which is 1/4. To find 1/4 of 28 it would be 28/4 which is 7. There are 7 juniors in the program.

5-cent: x

10-cent: y

25-cent: z

5x+10y+25z=320 which is also x+2y=5z=64. You can subsitute y for x+3 because he has 3 more 10-cent than 5-cent. x+x+3+z=23 which is 2x+z=20=z=20-2x.

Substitute

x+2(x+3)+5(20-2x)=64

x+2x+6+100-10x=64

7x=106-64

7x=42

x=6, z=20-2*6=8, z-x=8-6=2

Answer:

1240.4 mm²

Hope this helps!

Step-by-step explanation:

The surface area of the regular pyramid is the area of the base plus the area of the 5 triangles.

One triangle has the formula of [tex]\frac{1}{2}[/tex] × Base × ( Slant ) Height.

One triangle has the area of  [tex]\frac{1}{2}[/tex] × 16 × 20 = 8 × 20 = 160 mm²

160 mm² × 5 ( cause there are 5 triangles ) = 800 mm²

800 mm² + 440.4 mm² = 1240.4 mm²

Answer:

1240.4 mm²

Step-by-step explanation:

Surface area: add all of the sides' areas

Area of a triangle is 1/2 bh

1/2 (16)(20)=160(one side)

Since there are 5 sides we would do 160x5=800

Then adding the 2 areas together

440.4+800=1240.4

Answer:

(x, y) = (4, 11).

Step-by-step explanation:

We have two equations:

3(y-2x) = 9

x - 4 = 0

From equation 2, we have x = 4. We can substitute this value into equation 1 and solve for y:

3(y-2x) = 9

3(y-2(4)) = 9 (substitute x = 4)

3(y-8) = 9

3y - 24 = 9

3y = 33

y = 11

Therefore, the solution to the system of equations is (x, y) = (4, 11).

Answer:

The ratio of shirts Pete pays for to all the shirts Pete gets is 5:6.

5/6 of 1,200 is 1,000.

1,000 × $10 = $10,000

Pete would pay Jun 1,200 × $8 = $9,600 for the shirts.

Answer: $41.81 in total

Step-by-step explanation:

3.48 x 2.5 = 8.7

8.26 x 2.5 = 20.65  

4.98 x 2.5 = 12.45

8.7 + 20.65 + 12.45 = $41.8

The cost of chocolate pretzels for 2.5 pounds is $8.7.

The cost of almonds for 2.5 pounds is $20.65

The cost of trail mix for 2.5 pounds is $12.45.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

$3.48 chocolate pretzels

$8.26 almonds

$4.98 trail mix

So, the cost of chocolate pretzels for 2.5 pounds

= 3.48 x 2.5

= $8.7

and, the cost of almonds for 2.5 pounds

= 8.26 x 2.5

= $20.65

and, the cost of trail mix for 2.5 pounds

= 4.98 x 2.5

= $ 12.45

Answer:

The approximate diameter of each tire on Jasmine's bicycle can be calculated by dividing the circumference by π (pi). Using the given circumference of 70.4 inches and rounding π to 3.14, the calculation would be as follows:Diameter = Circumference / π

Diameter = 70.4 / 3.14

Diameter ≈ 22.45 inches (rounded to the nearest hundredth)So, the approximate diameter of each tire on Jasmine's bicycle is 22.45 inches.

The approximate diameter of each tire is 22.42 inches.

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The circumference of a circle is expressed mathematically as;

C = 2πr

or

C = πd

Where r is radius, d is diameter, and π is constant pi ( π = 3.14 )

Rearrange this formula to solve for the diameter:

C = πd

d = C/π

Substituting the given value of the circumference, we have:

d = 70.4/3.14

d = 22.42 in

Therefore, the diameter is 22.42 in.

Answer:

Equation: x=45,000 ÷ 3

Answer: 15,000

Step-by-step explanation:

We know that 2/3 of the pens produced in the factory are black. That means that 1/3 of the pens produced in the factory are blue.

If 45,000 pens are produced, then 1/3 of 45,000 will give us the number of blue pens, or x. Now with our equation, we can start solving.

x = 45,000(1/3) is the same thing as x = 45,000 ÷ 3.

45 ÷ 3 is 15. Now we can just add the zeros back in.

x=15000

Therefore, the number of blue pens, or x, is 15,000.

All the best on your homework!

Answer:

∡4 = 146°

Step-by-step explanation:

First, we need to find the value of ∡2, and keep in mind that the sum of all the angles in a triangle is = 180°.

Since the triangle is a right angle, we know that the angle to the bottom right = 90°. The other angle is 56°.

Since there are only 3 angles, let's add 56° and 90° to find ∡2.

56 + 90 = 146

180 - 146 = 34°

∡2 = 34°.

Now that we've found ∡2, we need to find out what type of angles ∡4 and ∡2 are.

They are supplementary angles, since they add up to 180°.

Let's subtract 180 - 34 to give us the value of ∡4

180 - 34 = 146

Therefore ∡4 = 146°

∡4 = 146°
