4. 2 badges

Step-by-step explanation: for number 4

Mr.Garcia is making badges. Each badge has 3/8 yards of ribbon. He starts with 3/4 yard of ribbon. We need to find how many badges he can make. The length of each badge is 3/8 yard of ribbon. The total length of the ribbon is 3/4 yard. To find the number of the badges is the quotient of the division of the total length of the ribbon by the length of each badge. The number of badges =  the length of the ribbon ÷ the length of the badge. The number of badges = 3/4 ÷ 3/8. To solve the division of two fraction we change the division sign by the multiplication sign and reciprocal the fraction after the division sign. The number of the badges = 3/4 × 8/3. The number of the badges = 3*8/4*3=24/12=2. So he can make 2 badges

1. What is a formula that can be used to find the area of one triangular section of the door?
2. How do you know the formula will work?

Answers

Answer:

[tex]A=\frac{ab}{2}[/tex] or [tex]A = a *\sqrt{c^2-a^2} /2[/tex]

Step-by-step explanation:

Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.

[tex]A = \frac{h_{b}+b}{2}[/tex]

Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.

By using trigonometric relations we will see that the area is:

How to find the area of one triangular section?

Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.

Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).

h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:

tan(60°) = x/h

x = tan(60°)*h

Then our two catheti are h and tan(60°)*h.

This means that the area will be:

Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

um what does this mean. Which number has factors besides 1 and itself?

Answers

Answer:

A composite number is a number that has at least one factor besides 1 and itself, or any number which is not prime (although the number 1 is neither prime nor composite). For example, 91 is a composite number. To determine whether a number is composite, determine whether or not it is prime.

Step-by-step explanation:

I don't know if this is the right answer or thread equation but here

"Which number has factors besides 1 and itself?"

Answer: Composite Number

A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself.[1][2] Every positive integer is composite, prime, or the unit 1, so the composite numbers are exactly the numbers that are not prime and not a unit.[3][4]

For example, the integer 14 is a composite number because it is the product of the two smaller integers 2 × 7. Likewise, the integers 2 and 3 are not composite numbers because each of them can only be divided by one and itself.

The composite numbers up to 150 are:

4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100, 102, 104, 105, 106, 108, 110, 111, 112, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 128, 129, 130, 132, 133, 134, 135, 136, 138, 140, 141, 142, 143, 144, 145, 146, 147, 148, 150.

You would simply multiply $0.09 and 12.  Decimals are frequently multiplied by treating them as whole numbers before placing the decimal point in the result. Where the decimal point is placed in the solution depends on how many digits are present in the factors following the decimal points. For instance, 0.3 x 0.8 equals 0.24.

What is the measure of an interior angle of a regular decagon?

18°

144°

180°

36°

Answers

Answer: 180

Step-by-step explanation:

Answer:

Step-by-step explanation:

A decagon has 10 sides so its interior angles add up to 180(10) - 360 = 1440 degrees. Therefore, on average, each interior angle is 144 degrees and each exterior angle is 36 degrees. The sum of the exterior angles is 10 x 36 = 360 degrees.

S:{−5}
S:{3}
S:{12}
S:{42}
I WILL GIVE BRAINIEST FOR THIS ONE!!

Answers

Answer:

The integer that makes the inequality false is D, 42

Step-by-step explanation:

Start the problem by expanding the inequality.

[tex]3\left(n-6\right) = 3n-3\times 6\\=3n-18\\----------\\2\left(n+12\right) = 2n+2\times 12\\=2n+24\\----------\\= 3n-18 < 2n+24[/tex]

Add 18 to both sides. When doing inequalities, always add the singular number or coefficient on the left side. Afterwards, simplify.

[tex]=3n-18+18 < 2n+24+18\\=3n\left(-18+18\right)\\=-18 + 18\\=3n-\left(0\right) < 2n+24+18\\=2n\left(24 + 18\right)\\=24 + 18\\=42\\=3n-\left(0\right) < 2n+42\\=3n < 2n+42[/tex]

Subtract by 2n, the coefficient on the right side.

[tex]3n-2n < 2n+42-2n\\=3n-2n < \left(2n+(42)-2n\right)\\= \left(2n+(-2n)\right)\\=3n-2n < 0+42-0\\3n-2n = 3-2\\= 1\\= "n"\\= 1n\\= 1\times n\\= 1\:or\:"n"\\= n < 42[/tex]

Given that n is less than 42, we can conclude that 42 would make the inequality false.

You want to get x alone:

Subtract 18 from both sides

Rewrite:

6x= 72-18
