Answer:

5

Step-by-step explanation:

25% of 20=5

Answer:

5 items are peeps

Step-by-step explanation:

25% is 1/4 of 100%, so divide 20 (your total # of items) by 4, and you get 5, which is 25% of your 20 spring basket items.

Step-by-step explanation:

4x+5<5x+3

4x=-5<5x=-3

x=-5/4<x=-3/5

Answer:

4 inches

Step-by-step explanation:

of 11 inches of wire costs 44 cents, then 1 inch of wire costs 4 cents because 44 cents ÷ 11 inches = 4 cents per inch. (44 ÷ 11 = 4)

So, if 1 inch is 4 cents, 16 cents is 4 inches because 16 ÷ 4 = 4

The common difference of this Sequence is 12.

In mathematics, a sequence refers to an ordered list of numbers. When working with sequences, there are various concepts and formulas that are used to calculate different aspects of the sequence. One such concept is the common difference. Let's explore what the common difference is and how to calculate it.
What is the common difference?
The common difference in a sequence refers to the difference between any two consecutive terms in the sequence. For example, in the sequence 2, 4, 6, 8, 10, the common difference is 2. We get this value by subtracting the second term (4) from the first term (2) and so on.
How to find the common difference of a sequence?
To find the common difference of a sequence, you need to know at least two terms of the sequence. You can then subtract one term from the other to calculate the common difference.
Let's apply this to the given sequence, which has a first term of 5 and a fifth term of 17. To find the common difference, we can subtract the first term from the fifth term as follows:
17 - 5 = 12
Therefore, the common difference of this sequence is 12.

Answer:

(3x + 2)(x-4)

Step-by-step explanation:

3x² - 10x - 8 = 0

(splitting the middle term)

3x² -12x + 2x -8 = 0

3x(x-4) + 2(x-4) = 0

(3x + 2)(x-4) = 0

(3x + 2)(x-4) is the correct answer (option a)

Answer:

Step-by-step explanation:

-(3x)²

In PEMDAS, we solve the exponent first then multiply.

-(3x)²

-(9x²)

-9x²

Best of Luck!

Uisng the PEMDAS method of simplifying arithmetic expressions, the expression would be 9z²

Given the expression :

This can be written as :

-3z × - 3z

Negative values will cancel out,

= 9z²

Therefore, the simplified form of the expression would be 9z²

Answer:

x=$1850

Step-by-step explanation:

Let the original price of the computer model is x.

Last years discount is 20%

We need to find the original price if the computer now costs $1480.

ATQ,

[tex]x-20\%\ \text{of x}=1480\\\\x-\dfrac{20x}{100}=1480\\\\x-\dfrac{x}{5}=1480\\\\\dfrac{4x}{5}=1480\\\\x=\dfrac{1480\times5}{4}\\\\x=\$1850[/tex]

So, the original cost of the computer model is $1850.

Answer:

The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9

Step-by-step explanation:

Fraction of Portion

Suppose we have a number n and another number m such as m>n. The portion or fraction of size n of m is given by the quotient n/m.

For example, 3 pieces of cake out of a total of 6 make them a fraction of 3/6 = 1/2 of the whole cake, i.e. half of the total available.

Mrs. Manning needs 1/3 cup of flour to make cookies for the bake sale. She actually has 3/4 cups of flour. Calculate the fraction of needed against the available flour:

[tex]\displaystyle \frac{\frac{1}{3}}{\frac{3}{4}}[/tex]

The division can be easier performed by multiplying by the reciprocal of the denominator:

[tex]\displaystyle \frac{1}{3}\cdot \frac{4}{3}=\frac{1*4}{3*3}[/tex]

[tex]\displaystyle =\frac{4}{9}[/tex]

The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9

Step-by-step explanation:

u do 198 divided by 4 then add 19 to the awnser that u got

Answer:

width = 40 feet

Step-by-step explanation:

If w = width, then l = 19 + w

l = 19 + w

2l + 2w = 198

"Substitute 19 + w as l in the second equation"

2(19 + w) + 2w = 198,

38 + 2w + 2w = 198,

38 + 4w = 198,

4w = 198 - 38 = 160,

w = 160/4 = 40 feet

=> Solution: width = 40 feet

Both answers are correct

Step-by-step explanation:

both y = 1 - 3/2x and y = 1 + -3/2x are correct answers, it is just that y= 1 - 3/2x is the simpler version. Adding a negative number is the same as subtracting a positive.

Answer:

A

Step-by-step explanation:

YESYESYESYESYESx85

You can solve with many ways but I'll do this one instead. Move 12 to the left side and change from positive to negative.

[tex]2x^2-2x-12=0\\[/tex]

Then divide by 2 whole equation.

[tex]\frac{2x^2-2x-12}{2}=\frac{0}{2}[/tex]

Simplify, as we get  [tex]x^2-x-6=0[/tex]

We can either use Quadratic Formula or Factoring the Polynomials. It depends but since the polynomial aren't that hard to factor because it doesn't have that many numbers in value. So using factoring will be faster.

From [tex]x^2-x-6=0[/tex] we can factor as -

[tex](x-3)(x+2)=0\\x-3 =0, x+2=0\\x=3, x=-2\\(x=3,-2)#[/tex]

Thus, the value of x is 3 or -2. So x = 3, -2 is the answer.

Note that we can also use Quadratic Formula to solve the equation, however that will take longer than factoring then solve the equation.

Answer: D)[tex]\sqrt{3}[/tex]

Step-by-step explanation:

cot(θ) = cos(θ) ÷ sin(θ)

cot(30) = [tex]\frac{\sqrt{3} }{2}[/tex] ÷  [tex]\frac{1}{2}[/tex]

cot(30) = [tex]\sqrt{3}[/tex]

The value of cot30 is √3 if sin30 = 1/2 and cos30 = √3/2 option (D) is correct.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

sin30 = 1/2

cos30 = √3/2

As we know,

cotA = cosA/sinA

A = 30 degrees

cot30 = cos30/sin30

cot30 = (√3/2)/(1/2)

cot30 = √3

Thus, the value of cot30 is √3 if sin30 = 1/2 and cos30 = √3/2 option (D) is correct.
