Hey factory could produce 84 toy robots in one day. The purchasing equipment. Now they can produce 105 robots in one day. What i

Finger [1]

Answer:

The answer to the question is

25 % increase in production rate

Step-by-step explanation:

To solve the question, we note that

Initial number of products = 84 toy robots per day

Present production rate = 105 robots per day

The percentage increase is given by the increase in production rate divided by the original production rate multiplied by 100

Where increase in production rate = 105 - 84 = 21

Percentage increase = 21/84 ×100 = 25 % increase

Special triangles 2 back

AleksAgata [21]

Answer:

Step-by-step explanation:

10. From the given figure,

$\frac{18}{y}=sin60^{0}$

$y=\frac{36}{\sqrt{3}}$

11. From the given figure,

$\frac{12}{y}=sin60^{0}$

$y=\frac{12{\times}2}{\sqrt{3}}=\frac{24}{\sqrt{3}}$

and $\frac{x}{y}=cos60^{0}$

$x=\frac{24}{\sqrt{3}{\times}2}=\frac{12}{\sqrt{3}}$

12. The sides of an equilateral triangle has length=10 inches, therefore AB=BC=AC=10

Also, AD is the height of the given triangle,then BD=DC=5

From triangle ADC,

$(AC)^{2}=(AD)^{2}+(DC)^{2}$

$100=(AD)^{2}+25$

$75=(AD)^{2}$

$AD=\sqrt{75}inches$

Hence, height of the triangle is $\sqrt{75}inches$

13. Height of the ramp from the ground is 8ft.

therefore, let BC=x

$\frac{8}{BC}=tan30^{0}$

$\frac{8}{x}=\frac{1}{\sqrt{3}}$

$x=8\sqrt{3}$

14. Let BC=x and AB=y

then, $\frac{x}{18}=cos30^{0}$

$x=18{\times}\frac{\sqrt{3}}{2}=9\sqrt{3}$

and $\frac{y}{x}=tan30^{0}$

$y=9$

The perimeter of triangle is=Sum of all the sides=AB+BC+AC= $9\sqrt{3}+9+18= 9\sqrt{3}+27=9(1.73)+27=42.57 inches$

15. Let AB be the height of the tree, then

$\frac{AB}{8}=tan30^{0}$

$AB=8{\times}\frac{1}{\sqrt{3}}=\frac{8}{1.73}=4.62m$

16. According to question,

$\frac{h}{24}=sin30^{0}$

$h=\frac{24}{2}=12ft$

Which statement best describes the expression 3 + 2 ÷ y?

JulsSmile [24]

Answer:

C. The sum of 3 and the quotient of 2 and y

Step-by-step explanation:

Given : 3 + 2 ÷ y

Solution:

First consider the BODMAS rule

solving any equation we need follow this sequence (BODMAS)

B - Bracket

O - Of

D- Division

M- Multiplication

A - Addition

S - Subtraction

So, in the given equation we first consider the division after that the addition

i.e. division of 2 by y (quotient of 2 and y) and then addition of 3 in the result of division of 2 by y

So, we can say it as The sum of 3 and the quotient of 2 and y
