Answer:

10 wedges

Step-by-step explanation:

To find the number of wedges, the total weight should divided by weight of  one wedge.

[tex]\text{Number of Wedges = $2.5 \div 0.25$}\\[/tex]

                              [tex]= \dfrac{2.5*100}{0.25*100}\\\\\\=\dfrac{250}{25}\\\\\\= 10 \ \sf wedges[/tex]

Using proportions, it is found that it will take him at least 135 minutes to shovel the driveway at this rate.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, it takes 45 minutes to shovel 240 ft². How long does it take to showel 720 ft²? The rule of three is given by:

45 min - 240 ft²

n min - 720 ft²

Applying cross multiplication:

240n = 45 x 720

n = 45 x 720/240

n = 45 x 3

n = 135

It will take him at least 135 minutes to shovel the driveway at this rate.

Answer:

Step-by-step explanation:

4 686.144+3 600+36 000

=44 286.144

Step-by-step explanation:

120° + 20° + x = 180° ( sum of interior angle. of triangle is 180°)

140° + x = 180°

x = 180° - 140°

x = 40°

Now

y + x = 180° ( supplementary angle)

y + 40° = 180°

y = 180° - 40°

y = 140°

The angle measure of y is 140°.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Given:

The three angles of a triangle are 120°, 20° and x.

And we know,

the sum of the interior angle of the triangle is 180°.

120° + 20° + x = 180°

140° + x = 180°

x = 180° - 140°

angle measure of x = 40°

Now:

Here, x and y are supplementary angles.

Supplementary angles are two angles whose measures add up to 180°

y + x = 180°

y + 40° = 180°

y = 180° - 40°

y = 140°

Therefore, the value of y is 140°.

Answer:

5.5 pounds

Explanation:

weight in kg = 2.5 kilograms

conversion:

1 kg ↔ 2.205 pounds

solve:

Answer:

5.5 pounds (nearest tenth)

Step-by-step explanation:

1 kilogram = 2.20462262 pounds

To determine how many pounds are in 2.5 kg, multiply by 2.5:

⇒ 2.5 kilograms = 2.20462262 × 2.5

                           = 5.5 pounds (nearest tenth)

Answer:

90 is the orrect answer because I said so

Step-by-step explanation:

Answer:

The answer is a = 99

Step-by-step explanation:

We can solve this using ratios

First we set up the equation:

[tex]\frac{a}{90}= \frac{110}{100}[/tex]

Then cross-multiply:

[tex]100 * a = 90 * 110[/tex]

Simplify:

[tex]100 * a = 9,900[/tex]

Divide both sides by 100:

[tex]a = 99[/tex]

Ta-Da! The answer is a = 99

Answer:

16

Step-by-step explanation:

We could use the distance formula to find the distance between the points in this problem, but when we look we see that the sides of the rectangle are parallel to the x and y-axis for each pair of sides. The first two points have a distance of 3 because 4-1=3. Since it is a rectangle, the opposite side will have the same length. For the sides perpendicular, we look at the points with the same x coordinate. Using (4,2) and (4,-3), we can calculate the length of the side by finding the distance by adding the absolute values of the y coordinate. 2+3=5. This means that the triangle has two sides with a length of 5 and two sides with a length of 3. Adding these together, 5+5+3+3 = 16.

The surface area of the hexagonal pyramid is the amount of space on it

The given parameters are:

This is calculated using:

V = 1/3Bh

So, we have:

V = 1/3 * 41.5 * 6

Evaluate the product

V = 83

Hence, the volume of the pyramid is 83 cubic centimeters

This is calculated using:

S = L + B

Given that:

A hexagonal pyramid has 6 lateral sides.

So, we have:

S = 6 * 14 + 41.5

Evaluate

S = 125.5

Hence, the surface area is 125.5 square centimeters

Answer:

  200

Step-by-step explanation:

Of the apartments in the building, 20% are singles and 70% of those do not have balconies.

That is, (0.20 × 0.70) = 0.14 of the building's apartments are singles without balconies. That is 28 apartments. If A is the number of apartments in the building, this means

  0.14A = 28

  A = 200 . . . . . divide by 0.14

There are 200 apartments in the building.

The weight of sand in the mixture when the weight of the clay in the mixture is 6.25 pounds is 4.69 pounds.

The equation can be represented as follows:

3c = 4s

3c = 4s

where

Hence,

3c = 4s

4s = 3c

let's make s the subject of the formula, since, we want to find s when c = 6.25 pounds

s = 3 / 4 c

s = 3 / 4 × 6.25

s = 18.75 / 4

s = 4.6875

s = 4.69 pounds

Answer:

slope: 5

y-intercept: 0

Equation: [tex]y=5x[/tex]

Step-by-step explanation:

First, lets find the slope.

Every time we have an increase in [tex]x[/tex], we have an increase in [tex]y[/tex].

To find that change, we will divide the changes in [tex]y[/tex] using two points.

I will be using the points [tex](1,5), (2,10)[/tex]

[tex]\frac{10-5}{2-1}[/tex]

[tex]=5/1[/tex]

[tex]=5[/tex]

Therefore, the slope is 5.

Next, lets find the y-intercept. The y-intercept is where the line goes through the y-axis.

We can go back 1 x-value (since when x = 1, y = 5)

Subtracting our slope (5) from the y-value for 1, we get:

[tex]y=0[/tex]

Therefore, the y-intercept is 0.

Finally, lets find the equation.

Linear equations are in the form [tex]y=mx+b[/tex], where m is the slope and b is the y-intercept.

Plugging those values in we get: [tex]y=5x+0[/tex]

Which will be simplified down to [tex]y=5x[/tex]
