Answer:

The weight of harry's dog written as a decimal is 12.875.

Step-by-step explanation:

Given : Harrys dog weighs $12\frac{7}{8}$ pounds.

To find : What is the weight of harry's dog written as a decimal ?

Solution :

Harrys dog weighs $12\frac{7}{8}$ pounds is written in mixed fraction.

Writing mixed fraction in fraction is $a\frac{x}{y}=(a\times y)+x$

$12\frac{7}{8}=\frac{12\times 8+7}{8}$

$12\frac{7}{8}=\frac{103}{8}$

Dividing 103 by 8 to write in decimal,

$12\frac{7}{8}=12.875$

Therefore, The weight of harry's dog written as a decimal is 12.875.

Instructions: The polygons in each pair are similar. Find the<br> missing side length.

loris [4]

Answer:

missing side length is 12

Step-by-step explanation:

similar means that all correlating pairs of sides have the same ratio (old side length) / (new side length).

so, when we know the ratio of one pair, we can apply it to any other side to calculate the correlating side.

we see, when we go from small to large, that we have the ratio 32/40 = 4/5.

so, multiplying the larger side by this, we get the shorter side.

15 × 4/5 = 3 × 4 = 12

the proportion part in your picture is a bit confusing :

yes,

x/15 = 32/40 = 32/40

I don't know, why this last expression was repeated.

x/15 = 32/40

x = 15×32/40 = 15×4/5 = 3×4 = 12

as you see we get of course the same result doing it that way.

A Triangle has an area of 36cm^2. The base and height are scaled by a factor of 5. What is the area of the resulting triangle?

Finger [1]

Answer:

Area of resulting triangle will be 900 $cm^2$ .

Step-by-step explanation:

When sides of any polygon if scaled by a factor of k

then area is scaled by $k^2$

According to the above statement

therefore here in the question since area of original triangle was 36 $cm^2$

and both base and height are scaled by a factor of 5.

therefore area of scaled triangle will be $5^2$ times of the original

that is 25 x 36 which gives 900 $cm^2$

So area of resulting triangle will be 900 $cm^2$

Consider angle θ in Quadrant II, where sinθ = 4/5 . What is the value of cosθ?

Kay [80]

Answer:

3/5

Step-by-step explanation:

sin theta=opposite/hypotenuse

4/5=opposite/hypotenuse

therefore opposite=4 and hypotenuse=5

for adjacent

using pythagoras theorem

a^2+b^2=c^2

opposite^2 + adjacent^2 =hypotenuse^2

4^2 + adjacent^2 =5^2

16 + adjacent^2 =25

adjacent^2 =25-16

adjacent = $\sqrt{9$

adjacent=3

cos theta=adjacent/hypotenuse

=3/5

therefore the value of cos theta is 3/5
