How does this work please

Answer:

3 * (½*2*5) = x

Step-by-step explanation:

Cost of carpeting = $3 per square foot

We have a triangular section to cover having the following dimensions:

base = 2 yd

height = 5 yd

First, let's find the area of the section = area of triangle

Area of triangle = ½*base*height

Area of the triangular section of the floor = ½*2*5

If $3 will cover 1 ft², therefore,

x will cover ½*2*5

Thus:

3 * (½*2*5) = x

Answer:

1. 3 = 5x2 – 10x

2. 8 = 5(x2 – 2x + 1)

3. StartFraction 8 Over 5 EndFraction = (x – 1)2

Step-by-step explanation:

3-4x=5x^2-14x

3=5x^2-14x+4x

3=5x^2-10x

5x^2-10x-3=0

1. 3 = 5x2 – 10x

2. 8 = 5(x2 – 2x + 1)

8=5x^2-10x+5

8-5=5x^2-10x

3=5x^2-10x

3. StartFraction 8 Over 5 EndFraction = (x – 1)2

8/5=x^2-2x+1

Cross product

8=5(x^2-2x+1)

8=5x^2-10x+5

8-5=5x^2-10x

3=5x^2-10x

Answer:

3 - 4x = 5x2 - 14x

= 3 - 5x2 = - 14x + 4x

=  3 - 10 = 10x

= 7 = 10x

= x = 7/10

= x = 0.7

Answer:

C. Multiply 1st equation by 3, then add together

Step-by-step explanation:

X+y=10

3(x+y)=3(10)multiply by 3

3x+3y=30 add to following equation

2x-3y=6

5x=36

Answer:

triangular pyramid

Step-by-step explanation:

The requried width of the crossbar for the H is 3.96 ft.

In a right-angled triangle, its sides, such as hypotenuse, perpendicular and base is Pythagorean triplets.

Here,

Let, from the figure,
b = 5

c = 1/2*6= 3
e = 1/2*b = 1/2*5 = 2.5

a = √[c²-e²]

a = √[3²-2.25²]

a = √9-5.0625

a = 1.98

x = 2a = 2*1.98=3.96

Thus, the requried width of the crossbar for the H is 3.96 ft.

Answer:

The probability that all 4 units are good is 10.66%.

Step-by-step explanation:

Given that a shipement of 14 microwave ovens contains six defective units, and a vending company has ordered 4 of these units and selection will be random, to determine what is the probability that all 4 units are good the following calculation must be performed:

14 - 6 = 8

8/14 x 8/14 x 8/14 x 8/14 = X

0.5714 x 0.5714 x 0.5714 x 0.5714 = X

0.1066 = X

0.1066 x 100 = 10.66

Therefore, the probability that all 4 units are good is 10.66%.

Answer:

x = -24

Step-by-step explanation:

y = 1/4x+12 (Substitute 6 for y)

6 = 1/4x+12 (Subtract 12 from both sides)

6-12= -6 so its now -6 = 1/4x and since its a fraction you want to multiply both sides by the reciprocal

4*-6 = 1/4x*4 (1/4*4=1 which is 1x or x)

-24 = x

Answer:

y=1/4x+12

6=1/4x+12

1/4x=6-12

1/4x=-6

0.25x=-6

x=-6÷0.25

x=-24

Step-by-step explanation:

first put the given value into the equation

Answer:

1.5x= y

Step-by-step explanation:

Speed = distance / time

The variable x represents time in hours and y represents yuri's distance from home in miles.

Therefore

Speed = y/ x

But distance = 5 miles and  speed= 1.5 miles

1.5 = y/x

or

1.5x= y

Answer:

2^6 x 10^5

Step-by-step explanation:

10^5

= ( 2 x 5 )^5

= 2^5 x 5^5

2 x 10^5

= 2^1 x 2^5 x 10^5

= 2^( 1 + 5 ) x 10^5

= 2^6 x 10^5

Answer: [tex]254.94\ ft[/tex]

Step-by-step explanation:

Given

Building A is 490 feet tall and building B is 754 ft tall.

If the angle of depression from building B to the top of building A is [tex]46^{\circ}[/tex]

Difference in the height of the two buildings is [tex]754-490=264\ ft[/tex]

If the difference between them is [tex]x[/tex]

From the figure, we can write

[tex]\Rightarrow \tan 46^{\circ}=\dfrac{264}{x}\\\\\Rightarrow x=\dfrac{264}{\tan 46^{\circ}}\\\\\Rightarrow x=254.94\ ft[/tex]

Therefore, the two buildings are [tex]254.94\ ft[/tex] apart.

Step-by-step explanation:

let the smaller number be x

5x - x = 52

4x = 52

4x÷4 = 52÷4

x = 13

the smaller number is 13

the bigger number is 5×13 = 65

Answer: C

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

The degree of a polynomial is the highest degree of a monomial contained within the polynomial. The degree of the monomial is the sum of the exponents on the variables. Example, the degree of -4x^6y is 6+1=7.

Example, the degree of 4x^8 is 8.

So the degree of 5x^4 is 4.

The degree of 3x^2 is 2.

The degree of 1 is 0 since there is no variable in this expression.

So the degree of 5 x^4 + 3 x^2 + 1 is 4.
