can someone explain this?

Answer:

b=45

Step-by-step explanation:

The two angles form a right angle. This is shown through the box drawn at the angle's vertex; this represents that it is a right angle. A right angle is equal to 90 degrees b can be found by using the other angle. Since 45 and b are complementary angles 45+b=90. This means that b must equal 45 degrees.

Answer:

the answer with the proportional relationship is "(D)"

The power of a river to cause erosion and carry sediment depends on several factors. A rivers slope, volume of flow, and the shape of its stream bed all affect how fast the river flows and how much sediment it can erode. ... When a river slows down, it drops its sediment load.

The velocity of the river that impact the capability for eroding the sediment should be explained below.

In the case when the slope should be considered too gentle and here the velocity should be too slow for transporting the sediments that being supplied via weathering and erosion also the sediments should be piled up.

It rised  the gradient that resulted the water to flow quickly that increased the erosion and transport due to which it decreased the gradient.

Answer:

Negative

Step-by-step explanation:

On the line, we see that a = 0.5 and b is after -1. a + b will be negative because anything after -1 added to .5 will be negative.

Example:

-1 + .5 = -.5

-2 + .5 = -1.5

-3 + .5 = -2.5

Answer: Negative

Step-by-step explanation: the b we can see is far away from  -1 that means its around - 2 and if we were to add 0.5 and - 2 we would get -1.5

Bottom side: 7c - 1

Tall side: 6c + 2

P = 7c - 1 + 6c + 2 + 3c - 2 + 2c + 4c + 1 + 4c + 2

P = 26c + 2

P = 26c + 2

P = 26(5) + 2

P = 132

The interior angles of any triangle must add up to 180° in measure. Right angles have measure 90°, so the missing angles in both triangles here have measure 45°.

In a 45°-45°-90° triangle, the legs and hypotenuse occur in a ratio of 1 : √2. This means

(1) x = 48 √2

(2) 88 = √2 x   →   x = 88 / √2 = 44 √2

You could also set up trigonometric equations to solve for x in each case:

(1) cos(45°) = 48 / x   →   x = 48 / cos(45°) = 48 / (1 / √2) = 48 √2

(2) cos(45°) = x / 88   →   x = 88 cos(45°) = 88 (1 / √2) = 44 √2

The work done by the man on the block during motion will be 50 Joule. Then the correct option is C.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The work done is given as,

W = F × D

Where F is the force and D is the displacement.

A man pushes a 10 kg block on a straight-level street by applying a power of 5 N. Thus, he moves the block at a distance of 10 meters with a speed increase of 0.2 m/s².

W = 5 × 10

W = 50 Joule

The work done by the man on the block during motion will be 50 Joule. Then the correct option is C.

The sum of the 48 terms will be $2,496. Then the correct option is A.

Let a₁ be the first term, n the number of the terms, and l be the last term of the sequence.

Then the sum of all the terms will be given as,

S = [n (a₁ + l )] / 2

Let a₁ be the first term and d is the common difference between the terms. Then the nth term will be given as

[tex]\rm a_n = a_1 + (n - 1)d[/tex]

Beginning with Rodney’s first month of high school, his father deposits $5 into Rodney’s savings account.

Each month after the first month, his father deposits $2 more than the previous month.

Then the first term is $5 and the common difference is $2.

The total amount deposited in Rodney’s account after four years can be represented using the expression.

Then the total number of the terms will be

n = 4 x 12

n = 48 months

Then the 48th term of the sequence will be

a₄₈ = 5 + (48 – 1) · 2

a₄₈ = 5 + 47 · 2

a₄₈ = 5 + 94

a₄₈ = 99

Then the sum of the 48 terms will be

S = 48 (5 + 99) / 2

S = 24 × 104

S = $2,496

Then the correct option is A.

Answer:

Any point greater Than 0 and less than 180°

Step-by-step explanation:

Obtuse angle measures are angles which measures angles in the range between 0° and 180°. Angles which lies between these range are called obtuse angles. Hence, from the question, if the ray of points measured does not point to 0° or 180°; then, the ray of angle points could have pointed to any angle between greater Than Zero less than 180.

Hence the points could 10 and 120 or any other values which meets the obtuse angle condition.

The values less than 4 or greater than 14 cannot be the length of the third side

From the question, we have the following parameters that can be used in our computation:

Side lengths of 9 and 5.

Represent the third length of the triangle with x

So, we have the following representation (using the triangle inequality theorem)

a + b ≥ c.

Substitute the known values in the above equation, so, we have the following representation

9 + 5 ≥ x

9 + x ≥ 5

5 + x ≥ 9

Evaluate the sum

14 ≥ x

x ≥ -4

x ≥ 4

So, we have

14 ≥ x

x ≥ 4

Combine

4 ≤ x ≤ 14

This means that values less than 4 or greater than 14 cannot be the length of the third side

The measure that  cannot be the length of the third side is 14. Option

An important rule to remember about triangles is called the third side rule:

Third side rule of triangles states that;

The length of the third side of a triangle is less than the sum of the lengths of the other two sides and greater than the (positive) difference of the lengths of the other two sides.

For this triangle, the length of the third side must be greater than

9- 5= 4

Also, the length of the third side must be less than

9 + 5 = 14

Hence,  all the answers are possible except for answer D, which is equal to 14 but not less than 14.
