Answer:

107

Step-by-step explanation:

it looks like a right angle

Answer:

The answer is 107 degrees.

Step-by-step explanation:

The sum of all the angle of a triangle must equal 180 degrees. That being said if you grab 180 and subract 44 and 29 from it you get 107 degrees. 107+44+29=180. If this did not equal 180 the answer would be wrong but since it does it is right.

Step-by-step explanation:

The original price of the radio is r112, and the VAT paid is r16.8.

To find the original price of the radio and the amount of VAT paid, we can use the formula:

Original price = Final price / (1 + VAT rate)

VAT paid = Final price - Original price

Given that the final price of the radio, including VAT, is r128.8 and the VAT rate is 15%, we can substitute these values into the formula:

Original price = 128.8 / (1 + 0.15)

VAT paid = 128.8 - Original price

Calculating the original price:

Original price = 128.8 / 1.15 ≈ r112

Calculating the VAT paid:

VAT paid = 128.8 - 112 ≈ r16.8

Therefore, the original price of the radio is approximately r112, and the VAT paid is approximately r16.8.

Answer:

y = -30

Option A

Step-by-step explanation:

y = -2x - 10

y = -5x + 20

We just need to substitute the values of y.

We have to equate both the equation.

-2x -10 = -5x + 20

-2x + 5x = 20 + 10

3x = 30

x = 10

Plug x as 10 in any one of the equation

Let's take the first equation

y = -2x  - 10

y = -2(10) - 10

y = -20 -10

y = -30

Answer:

$180

Step-by-step explanation:

$225 times .20 = 45 .   225-45=180

Answer:

$180

Step-by-step explanation:

Find 1% of the price.

100% = 225

1% = 225 ÷ 100 = 2.25

100 - 20 = 80% (Percentage of sale price)

80% = 2.25 x 80 = 180

The inequality w > 4 can be used to complete the following statements: The w in the inequality is the variable or unknown value being compared with the number 4. It represents an unknown quantity that is greater than 4.

The 4 in the inequality is the constant or known value that the variable w is being compared to. It is a number that is less than w.  

Inequalities use mathematical symbols to compare two values and express their relationship.

In this case, the inequality w > 4 uses the symbol ">" which means "greater than." The inequality indicates that w is larger than 4, so any value of w that is greater than 4 will make the inequality true.

The general solution to the equation +rtan 0 = 6 sec 0 tan 0 de is r = 6/cos 0.

This means that r can take any value that satisfies this condition, as long as there are no lost solutions.

To obtain the general solution, we start by simplifying the equation using trigonometric identities. We know that sec 0 = 1/cos 0, and we can substitute this into the equation to get:

r tan 0 = 6/cos 0 tan 0

Dividing both sides by tan 0, we get:

r = 6/cos 0

This is the general solution to the equation, as r can take any value that satisfies this condition. However, it is important to note that there may be lost solutions, which occur when the simplification process involves dividing by a variable that may be equal to zero for certain values of 0. Therefore, it is important to check for such values of 0 that may result in lost solutions.

Answer:

whats the question? I don't see anything.

Answer:

the price with the offer is going to be 1.59$

Step-by-step explanation:

\( \frac{x}{5.30} = \frac{70}{100} \)

\(100(x) = 70(5.30)\)

\(100(x) = 371\)

\( \frac{100(x)}{100} = \frac{371}{100} \)

\(x = 3.71\)

\(70\% \: \: \: of \: \: \: 5.30 \: \: \: is \: \: \: 3.71\)

The surface area of an object is the total area covered by the object's surface

The inequality that gives the maximum dimension of a cubic block covered twice with a quantity of paint that will cover 60 in.² is b ≤ √5

Question: The diagram in the question appear missing and an example diagram is included

The given parameters are;

The quantity of paint available = Cans of paint that will cover 60 in.²

The number of coats of paint to apply to the box =  2

Required:

To write an inequality representing the maximum edge length, b, in inches when the block is covered with a minimum amount of paint needed for two coats of paint

Solution:

From the diagram, we have;

The surface area of the cube = 6 × b²

The surface area covered by two coats of paint = 2 × 6 × b²

Therefore, we have;

The area of the block to cover ≤ The quantity of paint available

Which gives

2 × 6 × b² ≤ 60

b² ≤ 60/(2 × 6) = 5

b ≤ √5

The inequality that gives the maximum length of b that can be covered with the minimum amount of paint needed for two coats of paint is b ≤ 5

If Pet Design uses cost-plus pricing and prices most products like the original PetBed, then the price of the high-end PetBed will be $203.33   .

The sales price of the original PetBed is = $50 ;

The Original PetBed gross margin is = $35 ;

So , the ratio of the gross margin is = 35/50 ;

⇒ 0.7 = 70% ,

The cost to make the PetBed that production engineers and accountants believe is = $61 ;

So , The new PetBed cost is = $61 ;

The price of the high end PetBed is = $61/(100% - 70%) ;

= (61)/(30%)

The radius of the circle is approximately =71.96 units

Circles can be defined by their radii and all points on the circumference of a circle are equidistant from the center. Circles are widely used in mathematics, science and engineering for various applications, including modeling and solving problems in geometry.

The formula for the circumference of a circle is 2 * pi * r, where r is the radius.

Given the circumference, we can solve for the radius:

452.16 = 2 * pi * r

r = 452.16 / (2 * pi)

The radius of the circle is approximately 71.96 units.
