Answer:

1031 Meters

Step-by-step explanation:

You would use the Pythagorean Theorem to solve it which would be a^2 + b^2 = c^2 and a would be 800 and b would be 650 in this circumstance you would try to find C which would be glenn blvd.

The length of the Glenin Blvd road is 1030.77 m.

Step-by-step explanation:

Given,

Length if Main street (b) = 800 m

Length of Oak street (l) = 650 m

To find the length of Glenin Blvd (h) road

The given diagram forms a right angle triangle where Main street is the base, Oak street is the height and Glenin Blvd road is the hypotenuses.

Formula

Pythagoras theorem: b²+l² = h²

So,

h² = 800²+650²

or, h² = 1062500

or, h = 1030.77 (approx)

Hence,

The length of the Glenin Blvd road is 1030.77 m.

Answer:

8

Step-by-step explanation:

4-2=2

2x9=18

18+6=24

24/4=6

6+2=8

=8

To solve the expression [6+9 x (4-2)] ÷ 4+2, use the order of operations (PEMDAS), resulting in the answer 8.

The subject of this question is Mathematics and it involves the steps of evaluating the given mathematical expression, [6+9 x (4-2)] ÷ 4+2, which is a task typically encountered in middle school.

To solve this problem, we employ the Order of Operations, which can be remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Solve the expression in the parentheses: 4-2 = 2

Multiply 9 by the result from the parentheses: 9x2 = 18

Add 6 to the product: 6+18 = 24

Divide the sum by 4: 24 ÷ 4 = 6

Add 2: 6+2 = 8

Thus, [6+9x(4-2)] ÷ 4+2 equals 8.

Therefore, the length of an edge of cube is, 10 inches.

Answer:

36.7

Step-by-step explanation:

Divide it into 2 shapes: the cylinder and the cone

The volume of the cylinder is 1^2 * (13-2) * pi = 11pi

The volume of the cone is 1^2 * 2 * 1/3 * pi = 2/3 pi

11pi + 2/3pi = 11 2/3 pi

11 2/3 pi is approx. 36.7

Answer:

17

Step-by-step explanation:

y=mx+b

m is always the slope. In this m is 17.

The slope is the tangent of the curve thus the slope of y = 17x will be 17.

A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

The slope could be positive or negative.

A linear equation or function is given as ;

y = mx + b

Here, m is the slope.

At x = 0 ⇒ y = b so it will be a y-intercept.

By comparing y = 17x

m = 17

Hence "The slope of the given line will be 17".

Answer:

[tex]x = -17[/tex]

Step-by-step explanation:

Step 1:  Subtract 32x from both sides

[tex]36x + 32 - 32x = 32x - 36 - 32x[/tex]

[tex]4x + 32 = -36[/tex]

Step 2:  Subtract 32 from both sides

[tex]4x + 32 - 32 = -36 - 32[/tex]

[tex]4x = -68[/tex]

Step 3:  Divide both sides by 4

[tex]4x / 4 = -68 / 4[/tex]

Answer:

See explanation.

Step-by-step explanation:

Hello, your question is not very clear.

Based on the limited information, this is how we go about it.

If the rate at which people learn about a secret is directly proportional to the number of people who know the secret and 20 people know it on day 2, then the unit rate is 10.

That is the constant of proportionality is 10.

The direct variation equation is

[tex]y = 10x[/tex]

We want to find how long it will take take for a whole school population of 4000 people to know the secret.

We put y=4000 and solve for x.

[tex]4000 = 10x[/tex]

[tex]x = 400[/tex]

Hence it will take 400 days.

Given:

Funnel is in the shape of a cone.

Radius = 4 inches

Height = 10 inches

To find:

a) The volume of the funnel

b) How many quarts of oil are in the funnel.

Solution:

Volume of cone:

[tex]$V=\frac{1}{3}\pi r^2 h[/tex]

[tex]$V=\frac{1}{3}\times 3.14 \times 4^2 \times 10[/tex]

[tex]$V=167.47[/tex] in³

The volume of the funnel is 167.47 in³.

1 qt ≈ 58 in³

To convert cubic inch to quarts divide by 58.

[tex]$167.47in^3=\frac{167.47}{58}[/tex]

               = 2.9 quarts

Therefore 2.9 quarts of oil are in the funnel.

[tex] \bold{answer \: \: : } \\ \rm{volume = \frac{1}{3} \pi{r} ^{2} t} \\ = \frac{1}{3} \times 3.14 \times {(18 \div 2) }^{2} \times 8 \\ = \frac{1}{3} \times 3.14 \times {9}^{2} \times 8 \\ = \frac{1}{3 } \times {3.14} \times 81 \times 8 \\ = \frac{1}{3} \times 254.34 \times 8 \\ = \frac{1}{3} \times 2034.72 \\ = \frac{2034.72}{3} \\ = \boxed{ \boldsymbol{678.24 }\: \: \rm{units}}[/tex]

Final answer:

To find the 8th term in a geometric sequence, identify the common ratio and use the formula for the nth term. The 8th term of the sequence is 1.75.

Explanation:

Geometric Sequence:

Identify the common ratio: The common ratio is found by dividing any term by the previous term in the sequence. In this case, the common ratio is 0.5 (14/28 = 0.5).

Find the 8th term: Using the formula for the nth term of a geometric sequence [tex](a_n = a_1 * r^{(n-1)}),[/tex] plug in [tex]a_1 = 28[/tex], r = 0.5, and n = 8 to find the 8th term.

The 8th term of the sequence will be equal to 1.75.

Sunil can use scale factors to resize his photo. By multiplying the original dimensions by the scale factor, he can create photographs of different sizes. A scale factor greater than 1 will expand the photo, while a scale factor less than 1 will reduce its size.

Yes, Sunil can definitely use scale factors to make different sizes of the photo. The original dimensions of the photo are 2 inches by 3 inches. A scale factor is a number which scales, or multiplies, some quantity. In this context, the quantity is Sunil's original photo. If Sunil wanted to double the size of his photo, for example, he would use a scale factor of 2. This would make his new photo 4 inches by 6 inches.

Similarly, if he wanted to make his photo smaller, he could use a scale factor of less than 1. For example, a scale factor of 0.5 would result in a photo that is 1 inch by 1.5 inches. This is because 2 inches (width) times 0.5 equals 1 inch, and 3 inches (height) times 0.5 equals 1.5 inches.

In this example, the minute hand is our radius, because it’s half the internal length of the circle.

The circumference of the circle is equal to pi x diameter.

Since diameter is twice the radius, we can do 5.25 x 2 = 10.5.

From there, we can substitute and solve.

pi x diameter

pi x (10.5)

If we’re representing pi as 3.14, the answer will come out to 32.97.

If we’re representing pi in its calculator function form, it’ll be roughly 32.986723.
