Mathematics

Answer:

x = 1,500

Step-by-step explanation:

We are given that

3% ⋅ x = 45

or 3/100 ⋅ x = 45

Multiply both sides by 100 and divide both sides by 3

x = 45 ⋅ 100/3

So:

x = 1,500

I hope this helps!

(Btw, if you're using a calculator you can just inter 45 ⋅ 100 ÷ 3, and that will give you the answer.)

Answer:

Step-by-step explanation:

3% of what number is 45......percent of base = amount

the percent is the number with the percent sign......so its 3%

the base is the number we are taking the percent of...so the base is unknown

the amount is the number that relates to the percent, it is a portion of the whole number...and it is 45

A chord is 10cm from the centre of a circle of radius 15cm. Find the length of the chord.
almond37 [142]

Answer: 21.44 cm

Step-by-step explanation:

Given

Radius r=15 cm

distance of chord from the center is 10 cm

From the figure, the length of the chord is AC

Applying Pythagoras

\Rightarrow AO^2=OB^2+AB^2\\\Rightarrow AB^2=15^2-10^2\\\Rightarrow AB^2=225-100=115\\\Rightarrow AB=\sqrt{115}=10.72\ cm

The length of the chord is AC=2AB=21.44\ cm

The scale drawing of a rectangular room measures 10cm long by 6cm wide. The actual width of the room is 9 metres. What is the ac
Snezhnost [94]

Answer:

48 meters

Step-by-step explanation:

The first thing is to calculate the scale, since we know both widths it is possible:

we pass the 9 meters to centimeters = 900 cm

900/6 = 150

So the scale would be 1: 150

Which means that the length is 150 times bigger.

10 * 150 = 1500cm or what equals 15m

the perimeter is the sum of all the sides, therefore:

P = 15 + 15 + 9 + 9

P = 48

Which means that the perimeter of the room is 48 meters

Are these triangles similar? if so, what postulate or theorem justifies that they are similar?
Karo-lina-s [1.5K]

Answer:

Yes The triangles are similar by SAS Similarity Theorem

Step-by-step explanation:

we know that

<u>Side-Angle-Side Similarity,</u> states that If an angle of a triangle is congruent to an angle of another triangle and if the included sides of these angles are proportional, then the two triangles are similar

In this problem

Angle  L is congruent with Angle Z

so

Verify if the included sides are proportional

so

\frac{LJ}{ZY}=\frac{KL}{XZ}

substitute the values

\frac{3}{1.5}=\frac{4}{2}

2=2 -----> is true

therefore

The triangles are similar by SAS
