Write an inequality for the given statement: Two-thirds of a number, decreased by 4, is less than 6.

Answers

Answer 1

Answer:

Answer:

$(2)/(3) x$ < is the answer.

Step-by-step explanation:

Let number be x

two third of x = $(2)/(3) x$

two third of x decreased by 4 = $(2)/(3) x$ -4

which is less than 6 therefore mathematically it equals

$(2)/(3) x$ -4< 6

Answer 2

Answer: $(2)/(3)$ x-4<6

To get $(2)/(3)$ of a number you have to multiply the number by $(2)/(3)$ , which gives you $(2)/(3)$ x then you subtract that by 4. The inquality faces the 6 because it is greater than $(2)/(3)$ x-4 based on the statement above. The inquality always faces the greatest number.

Answers

Answer:

$\boxed{\angle b = 12 \degree}$

Given:

$\angle a \: and \: \angle b \: are \: complementary \: angles\n \n \angle a = 78 \degree$

Step-by-step explanation:

Two Angles are Complementary when they add up to 90° (a Right Angle).

$= > \angle a + \angle b = 90 \degree \n \n = > 78 \degree + \angle b = 90\degree \n \n = > \angle b = 90 \degree - 78 \degree \n \n = > \angle b = 12 \degree$

What is the 217th digit after the decimal point in the repeating decimal 0.3456? How can i calculate this?

Answers

Well I think you mean $0.(3456)$ , I will try to explain as simple as I can ;p

First I would divide 217 by 4, because we need to find 217th digit in 4 digit repeating decimal:

$217/4=(217)/(4)=54(1)/(4)$

$54(1)/(4)$ it means that 3456 will be reapeted 54 times untill 217th digit, and $(1)/(4)$ means that the 217th digit will be the first of those 4 digits in this decimal, so your answer is:
The 217th number after the decimal point in this repeating decimal will be 3

of a yard in

Answers

Answer:

Jeniffer can mow 3 lawns in an hour.

Step-by-step explanation:

If It takes Jennifer 20 minutes to mow the lawn. We are also given the time she spends mowing lawns. This is 1 hour.

For our solution to be correct, we will have to first of all convert 1 hour to minutes.

1 hour = 60 minutes.

Jeniffer should be able to mow 60 / 20 lawns in an hour. This will be 3 lawns in an hour.

Riya is applying to her garden. She applies it at a rate of 25, 000 cm³ of mulch for every m² of garden space. At what rate is Riya applying mulch in m³/m²

Answer:

0.25m³/m²

Step-by-step explanation:

We are told the Riya sprays mulch at 250,000cm³ per m²

To find the rate at which Riya is spaying the mulch in m³/m² we would have to convert 250,00cm³/m² to m³/m²

1 cm³ = 1 × 10^-6m³

250,000 cm³ = x m³

Cross Multiply

1 cm³ × xm³ = 250,000cm³ × 1 × 10^-6 m³

x m³ = 250,000cm³ × 1 × 10^-6 m³/1 cm³

= 0.25m³

Therefore, the rate at which Riya is spraying the mulch = 0.25m³/m²

How high is the kite off the ground?Solution: We are given the reference angle of 40° and the hypotenuse (125 ft) and asked to find the opposite side, howhigh the kite is from the ground. We need to use the sine ratio. Let's set up our ratio first.Sin40= x/ 125Solve for a rounding to the nearest tenth.2=3This represents the height of the kite from Hudson.
