20 cubic feet.

From feet: length (ft) × width (ft) × height (ft) = cubic feet.

From inches: length (in) × width (in) × height (in) ÷ 1728 = cubic feet.

From yards: length (yd) × width (yd) × height (yd) × 27 = cubic feet.

Then solve for angle 2 which is congruent to angle 6

6(21) + 8 = 134

Is 2.8 greater than or less than 2.78? Pls answer

Answers

2.8 is greater than 2.78 :)


If you look in the tens place and compare the two numbers, you will see that 8 is greater than 7. That’s how you know that 2.8 is greater than 2.78
2.8 is greater than 2.78 because 2.8 would basically be 2.80 so you can just add 0 at the end cause that wouldn’t change anything. So 2.80 you can see is greater than 2.78 because .80 > .78

Use Law of Sines or Law of Cosines to solve for the missing parts of each triangle​

Answers

Answer:

Step-by-step explanation:

Given

The attached triangle

Find x

Using law of sine, we have:

[tex]\frac{a}{sin A} = \frac{b}{Sin B}[/tex]

So, we have:

[tex]\frac{x}{sin 32} = \frac{18}{Sin 100}[/tex]

Make x the subject

[tex]x = \frac{18 * sin 32}{Sin 100}[/tex]

[tex]x = \frac{18 * 0.5299}{0.9848}[/tex]

[tex]x = 9.685[/tex]

Write
1 quadratic function in
vertex form whose graph
has
the vertex (1,2) and passes
through the point (3,10)

Answers

Answer:

y = 2 ( x − 1 ) ^ 2 + 2

Step-by-step explanation:

y = a ( x − h ) ^ 2 + k

where vertex is (h,k) = (1,2)

h=1, k=2

y = a ( x − 1 ) ^ 2 + 2

sub ( 3,10)

10 = a (3 - 1)^2 + 2

a=2

y = 2 ( x − 1 ) ^ 2 + 2

A function is a relationship between inputs where each input is related to exactly one output.

The quadratic function in vertex form is given by:

y = a(x - h)² + k

(h, k) = vertex

The quadratic function in vertex form is y = 2(x - 1)² + 2.

What is a function?

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = x + 2 is a function.

We have,

Quadratic function in vertex form whose graph has the vertex (1,2) and passes through the point (3,10).

The quadratic function in vertex form is given by:

y = a(x - h)² + k

(h, k) = vertex

Now,

(h, k) = (1, 2)

Passes through (3, 10).

So,

10 = a(3 - 1)² + 2

10 = 4a + 2

8 = 4a

a = 2

Now,

The quadratic function in vertex form is y = 2(x - 1)² + 2

Thus,

The quadratic function in vertex form is y = 2(x - 1)² + 2.

Ed bus a box of eggs costing £2.30, two packs of bacon for £2.60 each and two tins of baked beans. He pays with a £10 note gets 80p change how much did the tin of beans cost?

Answers

Answer:

£0.85 for each

£1.70 for both

Step-by-step explanation:

Variable x = cost of baked beans

2.30 + 2(2.60) + 2x = 10 - 0.80

Use PEMDAS

2.30 + 5.20 + 2x = 10 - 0.80

7.50 + 2x = 9.20

Subtract both sides by 7.50

2x = 1.70

Divide both sides by 2 to isolate the variable

x = 0.85

Let's check our work by plugging this into our original equation

2.30 + 2(2.60) + 2(0.85) = 10 - 0.80

2.30 + 5.20 + 1.70 = 10 - 0.80

7.50 + 1.70 = 9.20

9.20 = 9.20

Q1: A number minus 4 is greater than 2 times a number

Answers

Answer:

x - 4 > 2x

(see below to solve for x if needed)

Step-by-step explanation:

"Greater than" is key word for the greater than symbol: >.

"A number" can be represented by x.

So "a number minus four" would be x - 4 and "two times a number" would be 2x.

So "A number minus 4 is greater than 2 times a number" is:

x - 4 > 2x

If you were to solve for x, it would be:

x - 4 > 2x

-x         -x

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

-4     > x

x < -4
