1 answer:
iren [92.7K]3 years ago

Answer:

m<ACD = 50^{o}

Step-by-step explanation:

From the question given, ΔACD is a right angled triangle. Then we can apply one of the properties of a triangle to it.

In the triangle ACD:

<ACD + <DAC + <ADC = 180 (sum of angles in a triangle)

<ACD + 40 + 90 = 180

<ACD + 130 = 180

<ACD = 180 - 130

<ACD = 50^{o}

With the application of the property of the sum of interior angles of a triangle, the measure of <ACD is 50^{o}.

Paladinen [302]

Answer:

X = 0     4     8     12

Y =  10   7     4      1

Step-by-step explanation:

Given:

Cost of one T shirt = $15

Cost  of one sweater = $ 20

To find :

The graph that will represent both number of T-shirts and sweatshirts = ?

Solution:

Let the number of t-shirts be x

The number of sweaters  be y

They want to rise a found of $200

Then  the equation to represent this situation is

15x + 20y = 200

By trial and error method

15(12) + 20(1) = 200

15(8) + 20(4) = 200

15(0) + 20(10) = 200

15(4) + 20(7) = 200

A cylinder soup has a radius of 1,6 in and is 5/7 in. tall what is the volume
nata0808 [166]

Answer:

V=0.0623\ inch^3

Step-by-step explanation:

Given that,

The radius of cylinder, r = 1/6 inch

The height of the cylinder, h = 5/7 inch

We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :

V=\pi r^2 h\\\\=3.14\times (\dfrac{1}{6})^2\times \dfrac{5}{7}\\\\V=0.0623\ inch^3

So, the volume of the cylinder is equal to 0.0623\ inch^3.
