Answer 1

Answer:

BC ≈ 5.44 m

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] , that is

cos27° = [tex]\frac{BC}{6.1}[/tex] ( multiply both sides by 6.1 )

6.1 × cos27° = BC , then

BC ≈ 5.44 m ( to 3 significant figures )

The proper angle for a ladder is about 75' from the ground. Suppose you have a 21 foot ladder. How high
can it reach?

Answers

The ladder gets propped against the house, making a 75 degree angle with the ground. We can use the fact that cos(75°)=base distance/length of ladder to figure out the length of the base. Multiplying both sides by length of ladder we get, length of ladder×cos(75°)=base distance.Nov 6, 2019

should each club raise to meet the fundraising goal?
12x - 100 > 500 12x + 100 > 500 12x - 100 ≥ 500 12x + 100 ≥ 500 12x - 100 < 500 12x +100 ≤ 500

Answers

Given:

A school fundraiser has a minimum target of $500.

Faculty have donated $100 and there are 12 student clubs that are participating with different activities.

To find:

The inequality for the given situation.

Solution:

Let x be the money raised by each club.

Number of clubs is 12. So, total money raised by 12 clubs is 12x.

Faculty have donated $100.

Total funds raised [tex]=12x+10[/tex]

A school fundraiser has a minimum target of $500. It means the total funds raised must be greater than or equal to $500.

[tex]12x+100\geq 500[/tex]

Therefore, the correct option is D.

How many square units is the surface area of the box corresponding to the net?

We have two squares of 4x4 units and 4 rectangles of 4x2 units, therefore

[tex]2 \cdot (4 \cdot 4)= 2 \cdot 16 = 32 \text{ squre units}[/tex]

[tex]4 \cdot (4 \cdot 2)= 4 \cdot 8 = 32 \text{ squre units}[/tex]

Total Area is therefore 32 + 32 = 64 square units

Solve the equation by factoring: 2x3 - 30x2 + 100x =0

Answers

Ok so first I am going to multiply the equations that need to be multiplied which will simply the equation down to 6-60+100x=0
My next step is going to be subtracting 60 from 6 which will simply my equation down even further to -54+100x=0
Now I am going to add -54 to both side so that my 100x is my itself which will simply my equation down to 100x=54
Our next step is to divide 100 by both side so that x is left by itself causing our answer to be 0.54!
Hope this helps!

For the second question tan(72) = x/20

x in radians ≈ -5.248....

x in degrees ≈ 61.553....

Answer:

for first one

Step-by-step explanation:

therefore,

let the angle C be X

124 + 96 + 94 + X = 360

314 + X = 360°

X = 360 - 314 = 46°

angle C = 46°

The answer is 40 I got you fam

Answer:

The angle x, has the measurement of 40°

Step-by-step explanation:

Step 1: Define complementary angles

Complementary Angles: Two angles are complementary when the sum of them is equal to 90°. For example, 30° and 60° are complementary because they add up to 90°.

Step 2: Figure out the complementary angle

Since ∠ABD and ∠DBC are complementary, that means that they should add up to 90°. Since the angle value of ∠ABD is 50°, that means that the angle value of ∠DBC should be 90° - 50° = x.

90° - 50° = x

40° = x

Answer: The angle x, has the measurement of 40°

Determine whether the equation has one solution, no solution, or infinite solutions.
Explain your reasoning.
9x + 2 = -4(x + 6)

Answers

Answer:

The equation has 1 solution.

Step-by-step explanation:

Because you don't get the same answer on both sides, this equation does not have infinately many solutions. Because you don't get an invalid answer, such as 1 = 0, this equation doesn't have one solution. When you solve this equation, you'd get something similar to this

9x-2 = -4x-24 (distributive property)

13x-2=-24 (combine like terms)

13x=-22 (additive property of inversion)

x = -22/13

which is a valid, real-world solution.
