Answer:

160 ounces

Which is 10 pounds

And 4410 chip packets will equal about a ton

Step-by-step explanation:

because 20 x 8 =160

35274/8 = 4409.25

*note 35274 ounces is equal to a ton

Answer:

4000 bags

Step-by-step explanation:

8 x 20 = 160 oz = 10 lb

2,000 lb = 1 ton

16 oz = 1b

2,000 x 16 = 32,000 oz = 1 ton

32,000/8 = 4,000 bags

Answer:

x = 24°

Step-by-step explanation:

Here we can see that 120° with the right angle is equal to 180° :

120° + right angle = 180°

then:

right angle = 180° - 120° = 60°

The right angle with 5x angle is equal to 180° too ;

right angle + 5x = 180°

solve for x :

5x = 180° - 60°

x = 24°

That its.

Step-by-step explanation:

The value of sec θ is -√2 in the interval 3π/2 < θ < 2π, where θ is the angle whose tangent is -1.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

We are given that tan θ = -1, and we need to find the value of sec θ in the interval 3π/2 < θ < 2π.

Since tan θ = -1, we know that θ is in the third quadrant, where both x and y coordinates are negative. In the third quadrant, the reference angle for θ is π - θ, so we have:

tan θ = -1 = tan(-π/4)

π/4 = π - θ

θ = 3π/4

Now, we can use the fact that sec θ is the reciprocal of cos θ, and find cos θ in the third quadrant.

In the third quadrant, cos θ is negative. We can use the Pythagorean identity to find cos θ:

sin²θ + cos²θ = 1

Since sin θ is positive and we know that θ is in the third quadrant, we have:

sin θ = -√(1 - cos²θ)

tan θ = sin θ/cos θ = -1

Substituting sin θ and simplifying, we get:

-√(1 - cos² θ)/cos θ = -1

√(1 - cos² θ) = cos θ

Squaring both sides:

1 - cos²θ = cos²θ

2cos²θ = 1

cos²θ = 1/2

cos θ = -√2/2 (since θ is in the third quadrant)

Finally, we can find sec θ:

sec θ = 1/cos θ = -√2

Therefore, the value of sec θ is -√2 in the interval 3π/2 < θ < 2π, where θ is the angle whose tangent is -1.

Answer:

y=4x-4

Step-by-step explanation:

Hi there!

we are given that a line has a slope of 4 and it contains the point (4, 12)

We want to write the equation of this line in slope-intercept form

Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept

As we are already given the slope, we can immediately substitute it into the formula.

Replace m with 4 in y=mx+b:

y=4x+b

Now we need to find b

As the equation passes through the point (4, 12), we can use it to help solve for b

Substitute 4 as x and 12 as y:

12 = 4(4) + b

Multiply

12 = 16 + b

Subtract 16 from both sides

-4 = b

Substitute -4 as b

y = 4x - 4

Hope this helps!

The surface area of the square pyramid net consisting of a square and four triangles is 380 sq. cm

The surface area of a square pyramid is equal to the sum of the ara of the base square and the four triangle.

Area of the base = 10cm * 10cm

Base area = 100 sq,cm

Find the area of a triangle

Area of triangle = 0.5 * 10 * 14

Area of a triangle = 70 square cm

Area of 4 triangles = 4(70) = 280 sq.cm

SA = 100 + 280

SA = 380 sq. cm

Hence the surface area of the square pyramid net consisting of a square and four triangles is 380 sq. cm

Using proportions, it is found that the rate of 31 mills means that their property tax is of 3.1%.

A proportion is a fraction of a total amount.

The Staff family pays a rate of 31 mills in property tax, which means that for each $1000, $31 is paid in tax. Hence the rate is given by:

The maximum shower time is an illustration of mean and median, and the conclusion is to disagree with Blake's claim

The question is incomplete, as the dataset (and the data elements) are not given.

So, I will answer this question using the following (assumed) dataset:

Shower time (in minutes): 6, 7, 7, 8, 8, 9, 9, 9, 12, 12, 12, 13, 15,

Calculate the mean:

Mean = Sum/Count

So, we have:

Mean = (6+ 7+ 7+ 8+ 8+ 9+ 9+ 9+ 12+ 12+ 12+ 13+ 15)/13

Mean = 9.8

The median is the middle element.

So, we have:

Median = 9

From the question, we have the following assumptions:

So, the dataset becomes: 6, 7, 7, 8, 8, 9, 9, 9, 10, 10, 10, 10, 10

The mean is:

Mean = (6+ 7+ 7+ 8+ 8+ 9+ 9+ 9+ 10+ 10+ 10+ 10+ 10)/13

Mean = 8.7

The median is the middle element.

So, we have:

Median = 9

From the above computation, we have the following table:

               Initial    Final

Mean         9.8        8.7

Median       9         9

Notice that the mean value changed, but it did not go below 8 as claimed by Blake; while the median remains unchanged.

Hence, the conclusion is to disagree with Blake's claim

We can solve this using the Pythagorean Theorem.

[tex]a^2+b^2=c^2[/tex] where [tex]a[/tex] and [tex]b[/tex] are the legs and [tex]c[/tex] is the hypotenuse.

Given:

1 leg = 13

2 leg = ???

hypotenuse = 15

Plug the values into the equation above:

[tex]13^2+b^2=15^2[/tex]

Multiply using exponents:

[tex]169+b^2=225[/tex]

Subtract 169 from both sides:

A) pyramid

Explanation:

When you take the cross-section of a pyramid parallel to the base, the cross-section will be in the shape of the base.

As you take cross-sections further up the pyramid, you will still get a cross-section that is in the shape of the base, but it will be smaller. This is because as you go further up the pyramid, the distance between vertices is shorter because it comes to a point.
