Answer:

3√3

Step-by-step explanation:

Below I have attached the template on how to solve 30-60-90 triangles

We see that the hyptonouse has a length equal to 2x which means that

2x= 6√3

x= 3√3

We then see (from the template) that the lenght opposite to the 30 degree angle is equal to x and therefore our answer is just 3√3

Answer:

70

Step-by-step explanation:

break down each of the three numbers into primes

10 = 2 x 5

14 = 2 x 7

35 = 5 x 7

multiply 2 x 5 x 7 = 70

Answer:

- 7

Step-by-step explanation:

6(- x - 3) = 24

-6x - 18 = 24

-6x = 24 + 18

-6x = 42

x = 42 ÷ - 6

x = - 7

16 units is the answer

Answer:

Noise level increase by 1.5 per unit increase in number of persons

Step-by-step explanation:

The slope, m of a linear model is the value which represents the unit change in the dependent variable due to a unit chahe in the independent dependent.

The maximum noise in decibel is the dependent variable while the number of persons is the independent variable. Hence, the Coefficient of the independent vatiabkw is the slope and gives the rate of change in the dependent variable per unit Change in the independent variable.

Answer:

formula is speed equals distance/ time.

now, speed above is 85km/h and distance is 42km.

time therefore is 42/85 which is 0.494h

now, 0.494h× 60 minutes is 29.64minutes(which is your answer in minutes)

now,29.64minutes × 60secs is 1778.82 seconds to the nearest seconds is 1779 seconds( which is your answer in seconds)

Answer:

5,500

Step-by-step explanation:

25% of 2,750 is 687.5

687.5 times 4 is 2,750

2,750 times 2 is 5,500

so you would have $5,500 in total in your account in 4 years

Step-by-step explanation:

[tex]3 \frac{3}{4} - 2 \frac{1}{5} \\ \\ = 3.75 - 2.2 \\ \\ = 1.55 \\ \\ = \frac{155}{100} \\ \\ = 1 \frac{55}{100} \\ \\ = 1 \frac{11}{20} [/tex]

149 rounded to the nearest hundredth is 12.2

Solve: Square root of 149 rounded to the nearest hundredth's.

Solution:

The square root of 149 cannot be simplified. √149 is already in its simplest radical form.

The square root of 149 is 12.2065556157

Rounding that number to the nearest tenth is equals to 12.2

Therefore, 149 rounded to the nearest hundredth is 12.2

Answer:

The first number line because a negative number plus a positive number would give you zero if the digit before the signs are the same (eg. -5+5=0)

The shapes that would be formed by the nets are:

a. Cuboid

b. square pyramid

A cuboid is a shape that is formed by the net that has six (6) flat faces with angles that are right angles.

The net in figure a above would form a cuboid shape when joined together.

A square pyramid is a thee-dimensional geometric shape that is formed by the net consists of a square base and four triangular sides which joined together at a common vertex.

The image attached below shows the shape that would be formed by the net in figure B, which would be a square pyramid.

Therefore:

a. Cuboid

b. square pyramid

Given:

A city's population has increased 40% in the last 5 years and is now 53,782 people.

To find:

The population 5 years ago.

Solution:

Let x be the population 5 years ago.

A city's population has increased 40% in the last 5 years.

So, present population is

[tex]x+x\times \dfrac{40}{100}=x+0.4x=1.4x[/tex]

It is given that the present population is 53782.

[tex]1.4x=53782[/tex]

[tex]x=\dfrac{53782}{1.4}[/tex]

[tex]x=38415.7142857[/tex]

[tex]x\approx 38416[/tex]

Therefore, the population 5 years ago was about 38416.
