The multiplication of 0.34 by 0.568 will be 0.19312 and the number of significant figures is five.

<h3>How to illustrate the information?</h3>

In positional notation, significant figures are the digits in a number that are trustworthy and required to denote the amount of something. Significant figures are the number of digits that add to the correctness of a value, frequently a measurement.

It should be noted that significant figures are the numbers that are reliable and are usually non zero digits.

In this case, the multiplication of 0.34 by 0.568 will be 0.19312.

Therefore, the number of significant figures is five.

Answer:

$16,557

Step-by-step explanation:

The computation of the amount after four years is shown below:

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= £15,000 × (1 + 2.5%)^4

= £15,000 × 1.025^4

= $16,557

Your friend's swimming pool is in the shape of a rectangular prism, with a length of 25 feet, a width of 8 feet, and a height of

RUDIKE [14]

Answer:

Part a) $V=1,000\ ft^{3}$

Part b) $h=5\ ft$

Part c) $=718\ gal$

Step-by-step explanation:

Part a) What is the volume of your friend's swimming pool?

we know that

The volume of a rectangular prism is equal to

$V=LWH$

substitute the values

$V=(25)(8)(5)=1,000\ ft^{3}$

Part b) Your swimming pool is in the shape of a cylinder with a diameter of 16 feet and has the same volume as your friend's pool. What is the height of your pool?

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

we have

$V=1,000\ ft^{3}$

$r=16/2=8\ ft$ ----> the radius is half the diameter

substitute and solve for h

$1,000=\pi (8)^{2} h$

$h=1,000/(64 \pi)$

$h=1,000/(64*3.14)=5\ ft$

Part c) While you were on vacation, 6 inches of water evaporated from your pool. About how many gallons of water evaporated from your pool?

remember that

$1\ ft=12\ in$

so

$6\ in=6/12=0.5\ ft$

Find the volume of water for $h=5-0.5=4.5\ ft$

$V=(3.14)(8)^{2}(4.5)=904.32\ ft^{3}$

so

the volume of water evaporated is equal to

$1,000\ ft^{3}-904.32\ ft^{3}=95.68\ ft^{3}$

convert to gallons

remember that

$1\ ft^{3}=7.5\ gal$

so

$95.68\ ft^{3}=95.68*7.5=718\ gal$

ali's tyre pressure gauge shows a reading witch is 8 % lower than the actual pressure when the gauge shows 33.58

Rama09 [41]

Answer:

the actual pressure is 31.09

Complete question:

What is the actual pressure when Ali's gauge shows 33.58

Step-by-step explanation:

Given,

Ali's tyre presser gauge show a reading 8% higher than the actual pressure.

Ali's gauge shows 33.58.

Let the actual pressure be x.

According to problem,

$x\times\frac{108}{100} =33.58$ { [If 8% increasing of a no ⇒ The number becomes = $(\frac{100+8}{100})$ of the number}

x= $\frac{33.58\times100}{108}$

x=31.09

Therefore, the actual pressure is 31.09

What is the point of intersection when the system of equations below is graphed on the coordinate plane?

lesantik [10]

Multiply the first equation by -2 gives:_
-2y = -8 + 2x

2y = 8 - 2x

adding these 2 equations:-

0 = 0

This shows that the 2 equations are equal so there are infinite solutions

$180 - 70 = 110$

$180 - 110 = 70$

$70 + 70 = 140$

$180 - 140 = 40$

so the answer is 40
