\dfrac{(2 \frac{5}{6}+1.75) \times 0.14 }{2 \frac{1}{3} \times 1.1  : 1.6}

First, do the one between the parenthesis, change the fraction into improper fraction and equalize the denominators
= \dfrac{(\frac{17}{6}+ \frac{175}{100} ) \times 0.14 }{2 \frac{1}{3} \times 1.1  : 1.6}
= \dfrac{(\frac{1700}{600}+ \frac{1050}{600} ) \times 0.14 }{2 \frac{1}{3} \times 1.1 : 1.6}
= \dfrac{\frac{2750}{600} \times 0.14 }{2 \frac{1}{3} \times 1.1 : 1.6}
= \dfrac{\frac{275}{60} \times 0.14 }{2 \frac{1}{3} \times 1.1 : 1.6}

Do the multiplication on the numerator, change 0.14 into proper fraction
= \dfrac{\frac{275}{60} \times  \frac{14}{100}  }{2 \frac{1}{3} \times 1.1 : 1.6}
= \dfrac{\frac{3850}{6000}}{2 \frac{1}{3} \times 1.1 : 1.6}

simplify
= \dfrac{\frac{77}{120}}{2 \frac{1}{3} \times 1.1 : 1.6}

do the multiplication on the denominators, change the fraction into proper/improper fraction
= \dfrac{\frac{77}{120}}{\frac{7}{3} \times  \frac{11}{10} : 1.6}
= \dfrac{\frac{77}{120}}{\frac{77}{30} : 1.6}

do the division, change decimal fraction into improper fraction
= \dfrac{\frac{77}{120}}{\frac{77}{30} :  \frac{16}{10} }

and turn the division into multiplication
= \dfrac{\frac{77}{120}}{\frac{77}{30} \times  \frac{10}{16} }
= \dfrac{\frac{77}{120}}{\frac{770}{480}}

simplify
= \dfrac{\frac{77}{120}}{\frac{77}{48}}

turn division of fraction into multiplication of fraction
= \frac{77}{120}:\frac{77}{48}
= \frac{77}{120} \times\frac{48}{77}
= \frac{48}{120}

simplify the result
= \frac{4}{10}
= 0.4

The result is 0.4

The exclamation point (!) on a billboard consists of a circle sector and circle. The radius of the sector is 9 ft, and the radiu
harina [27]

Answer:

  24.0 square feet

Step-by-step explanation:

The area of the sector is given by ...

  A = (1/2)r²θ . . . . . where θ is the angle in radians

The area of the circle is the same, with θ=2π, so is ...

  A = πr²

__

In this problem, the area of the sector is ...

  A = (1/2)(9 ft)²(24π/180) = 27π/5 ft² ≈ 16.9646 ft²

The area of the circle is ...

  A = π(1.5 ft)² = 9π/4 ft² ≈ 7.0686 ft²

Then the total area of the exclamation point is ...

  16.9646 +7.0686 ≈ 24.0 . . . ft²

The area is about 24.0 square feet.

Se tiene un rectángulo cuya base mide el doble que su altura y su área es 12
irina [24]

Answer:

Part 1) The perimeter is  P=6\sqrt{6}\ cm

Part 2) The diagonal is d=\sqrt{30}\ cm

Step-by-step explanation:

<u><em>The question in English is</em></u>

You have a rectangle whose base is twice the height and its area is 12

square centimeters. Calculate the perimeter of the rectangle and its diagonal

step 1

Find the dimensions of rectangle

we know that

The area of rectangle is equal to

A=bh

A=12\ cm^2

so

bh=12 ----> equation A

The base is twice the height

so

b=2h ----> equation B

substitute equation B in equation A

(2h)h=12\\2h^2=12\\h^2=6\\h=\sqrt{6}\ cm

Find the value of b

b=2\sqrt{6}\ cm

step 2

Find the perimeter of rectangle

The perimeter is given by

P=2(b+h)

substitute

P=2(2\sqrt{6}+\sqrt{6})\\P=6\sqrt{6}\ cm

step 3

Find the diagonal of rectangle

Applying the Pythagorean Theorem

d^2=b^2+h^2

substitute

d^2=(2\sqrt{6})^2+(\sqrt{6})^2

d^2=30

d=\sqrt{30}\ cm

Two trains leave stations 288 miles apart at the same time and travel towards each other. One train travels at 95 miles per hour
erma4kov [3.2K]
95x=85x+288
You could add 288 to any side, it just shows that they're 288 miles apart.
Let's subtract 85x from both sides.
10x=288
28.8=x
It'll take 28.8 hours for the trains to meet. Let's make sure.
28.8×95
2,736
28.8×85
2,448
2,736-2,448
288
So, they'll meet up after 28.8 miles.
