5 0

Answer:

65 yd

Step-by-step explanation:

The image of this walking path of Cristal is missing, so i have attached it.

From the image attached, we can see that the path "x" is the hypotenuse path a the triangle.

Thus, we can use pythagoras theorem to find the area. Thus;

x² = 16² + 63²

x = √(16² + 63²)

x = √4225

x = 65 yd

In a painting, The Great Pyramid of Giza is 45 centimeters tall.
777dan777 [17]

Answer:

The scale is: 1 cm = 3.26 meter

Step-by-step explanation:

Given

Height of Pyramid in Painting = H_p = 45 cm

Actual Height of Pyramid = H_a = 146.5m

In order to find the scale, we can find the ratio between actual height and height in painting.

The ratio can be found by dividing the actual height by height in painting

Scale = \frac{H_a}{H_p}\\= \frac{146.5}{45}\\=3.25555 m/cm

Rounding off to nearest hundredth

= 3.26

This means that the scale is:

1 cm = 3.26 meter

Find the ratio of a:b, if 2a-b/6=b/3
Katen [24]

Answer:

\frac{a}{b}=\frac{1}{4}

Thus, the ratio is:

a:b = 1:4

Step-by-step explanation:

Given the expression

2a-\frac{b}{6}=\frac{b}{3}

\mathrm{Add\:}\frac{b}{6}\mathrm{\:to\:both\:sides}

2a=\frac{b}{2}

Divide both sides by 2

\frac{2a}{2}=\frac{\frac{b}{2}}{2}

a=\frac{b}{4}

Divide both sides by b

\frac{a}{b}=\frac{1}{4}

Thus, the ratio is:

a:b = 1:4

A vendor sells pretzels and drinks at a corner stand. He charges $2.25 for a pretzel and $1.50 for a drink. One day, the vendor
Vanyuwa [196]
For this case, the first thing we must do is define variables:
 p: number of pretzels
 d: number of drinks
 We now write the system of equations:
 2.25p + 1.50d = 463.50
 p + d = 257
 Solving the system we have:
 d = 153
 p = 104
 Answer:
 104 pretzels
 
153 drinks
