Answer:

Step-by-step explanation:

Given similar figures with ratio of sides = a : b , then

ratio of areas = a² : b²

ratio of sides = 15 ; 18 = 5 ; 6

The ratio of perimeters is equal to the ratio of sides, so

ratio of perimeters = 5 : 6

ratio of areas = 5² : 6² = 25 : 36

Please can anyone help me answer this question I'm really struggling with it

Answer:

$v = {210cm}^{3}$

Step-by-step explanation:

Formula for finding the volume of a triangular prism is given as:

$v = \frac{1}{2} \times b \times h \times l$

where,

b = breadth = 7cm

h = height = 6cm

l = length = 10cm

Thus,

$v = \frac{1}{2} \times 7cm \times 6cm \times 10cm$

$v = \frac{1}{2} \times 420 {cm}^{3}$

$v = \frac{ {420cm}^{3} }{2}$

$v = {210cm}^{3}$

Barbra can walk 3,200 meters in 24 minutes. How far can she walk in three minutes.

lisabon 2012 [21]

Answer:

Step-by-step explanation:

To find how far she can walk in 3 minutes, we need to find how fast she can walk in 1 minutes. We do this by dividing the distance she walked by the time she walked. Lets do so.

3200/24=133.33

She walks 133.33 meters per minute. Now to find her distance in 3 minutes w multiply this number by 3.

133.33*3=400

Barbra walks 400 meters every 3 minutes.

write an equation in slope intercept form for the line that passes through (4, -4) and is parallel to 3x+4x=2y-9

photoshop1234 [79]

Answer:

$\large\boxed{y=\dfrac{7}{2}x-18}$

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

Convert the equation of a line 3x + 4x = 2y - 9 to the slope-intercept form:

$3x+4x=2y-9$

$7x=2y-9$ add 9 to both sides

$7x+9=2y$ divide both sides by 2

$\dfrac{7}{2}x+\dfrac{9}{2}=y\to y=\dfrac{7}{2}x+\dfrac{9}{2}$

Parallel lines have the same slope. Therefore we have the equation:

$y=\dfrac{7}{2}x+b$

Put the coordinates of the point (4, -4) to the equation:

$-4=\dfrac{7}{2}(4)+b$

$-4=7(2)+b$

$-4=14+b$ subtract 14 from both sides

$-18=b\to b=-18$

Finally we have the equation:

$y=\dfrac{7}{2}x-18$

Maru [420]

Answer:

Renata has a home loan for $150,000 at 7.5% interest for 30 years and her payment is $987.00 per month.

I have solved this using excel sheet that is attached here.

p = $150000

r = 7.5%

t = $30\times12=360$

EMI = $987

You can see the excel sheet, after first month principle is $ 149,950.50 and after second month it is $149,900.69 .
