Answer:

C: 24 = [tex]w^{2}[/tex] + 3 (the yellow option)

Step-by-step explanation:

We can see that 24 obviously represents our total area, we are told that the rug is 3 feet LONGER THAN it is wide, suggesting that addition will be involved.

In conclusion the most logical answer would be C: 24 = [tex]w^{2}[/tex] + 3

what is the factored form of the expression 4p^2-p-5?

Answers

Answer:

(4p - 5) (p + 1)

Step-by-step explanation:

We begin with the equation 4[tex]p^{2}[/tex]- p - 5.

We know that the coefficients of the variable p must multiply to make 4. We also know that their constants must multiply to make 5.

So, our first guess would probably be: (4p - 5) (1p + 1)

This would simplify to: (4p - 5) (p + 1)

We check if this is correct if we foil them out.

Question:

x + 3 < 5, Find x.

Answer

⟹ x + 3 < 5

( Subtracting 3 from both the sides of the inequality )

⟹ ( x + 3) - 3 < 5 - 3

⟹ x < 5 - 3

⟹ x < 2

It means that any number that is smaller than 2 will satisfy the inequality.

In the diagram below shows the cross section of a bridge with a semi circle hole. If the perimeter of the cross section is 24m. Calculate
B. Area of the cross section ( π =22/7)​

Answers

Answer:

the area is 85.239 m²

Step-by-step explanation:

perimeter of a semi circle = ½πd

24 = ½ x 22/7 × d

24 x 7/11 = d

15.27 m = diameter...

area = ½πr²

= ½ × 22/7 x 7.365 x 7.365

= 85.239 m2

Lydia bought 2 ½ gallons of paint and used 1 ½ gallons of paint. What fraction of the paint did she use?

Answers

3/5 is used

2 1/2 gallons can be expressed as 5/2
1 1/2 gallons is the same as 3/2the fraction used is amount used over total amount

So (3/2)/(5/2) the 2 s cancel leaving you with 3/5

The quantity of the paint used will be 3/5 for the paint.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Lydia bought 2 ½ gallons of paint and used 1 ½ gallons of paint.

The fraction will be calculated as below,

2 ½  gallons can be expressed as 5/2

1 ½ gallons is the same as 3/2 the fraction used is the amount used over the total amount.

Fraction = 3 / 2 ÷ 5 / 2

Fraction = 3 / 5

Find the missing length of the triangle.
4 yd
12; yd
2
yd

Answers

Answer:

Missing length = [tex]11\frac{2}{3}[/tex]

Step-by-step explanation:

By Pythagoras theorem,

Square of the longest length = Sum of square of smaller lengths of the triangle

[tex](\frac{37}{3})^2=a^2+4^2[/tex]

a² = 152.11 - 16

a² = 136.11

a = √136.11

a = 11.67 Or [tex]11\frac{2}{3}[/tex]

Therefore, missing length of the given triangle will measure [tex]11\frac{2}{3}[/tex] yd.

After taxes, Liza makes $2,185.76 each month. From that, she has to pay three bills. For the last month, one bill is for $73.49, another is for $897.19, and the third is for $474.31. How much money does she have left to spend for the month?

Answers

Answer:

the  amount left to spend is $740.77

Step-by-step explanation:

The computation of the amount left to spend is as follows:

= Each month payment - last month payment bills

= $2,185.76 - $73.49 - $897.19 - $474.31

= $740.77

Hence, the  amount left to spend is $740.77

We simply deduct three amount bills from the each month payment

A right triangle has legs with lengths 61 cm and 60 cm. What is the length of the hypotenuse

Answers

For this, use Pythagoras which is a^2 + b^2 = c^2.
61^2 + 60^2 = 7321
Now square root your value, 85.6

The answer is 85.6 cm

Answer:

We gotta use Pythagorean theorem, fellas!

a^2 + b^2 = c^2

c^2 is the hypotenuse being squared.

a is a leg of a right triangle

b is another leg of a right triangle

------------------------------------------------------

we will use 61 for a

we will use 60 for b

a^2 + b^2 = c^2

61^2 + 60^2 = c^2

3721 + 3600 = c^2

7321 = c^2

[tex]\sqrt{7321}[/tex] = c (remember that c is hypotenuse)

c is rounded to 85.56 cm or 85.563 cm or 86 cm (depends on how the question wants the answer to look like)
