Answer:

x = 44⁰

y = 46

z = 90⁰

m = 36⁰

n = 40⁰

Step-by-step explanation:

a) Opposite angles of a parallelogram are always equal, so x = 44. The 4 angles will add up to 180⁰, so when you add the two 44⁰ angles together and subtract from 180⁰, you get 92⁰. divide that by 2 and you get 46⁰, so y = 46⁰.

b) since the two sides are parallel, if the other side is perpendicular to one, causing the 90⁰ angle, it is also perpendicular to the other, so z = 90⁰.

c) Opposite angles over a common side are equal, so m = 36⁰.

d) You know the missing angle in the small on the right is 40⁰ because the three angles will add up to 180⁰ and the two known angles add to 140⁰. Then you can use the same reason above to figure that the angle next to 65⁰ is 40⁰. The hashes on the sides of the bigger triangle on the left show it is an isoceles triangle in which the two base angles are always equal, so since you know the one is 40⁰, you know that n = 40⁰ also.

A retangular prism has a length of 20 in. a width of 2 in., and a height of 3 1/4 in. The prism is filled with cubes that have e
ira [324]

Answer: 8320 cubes.

Step-by-step explanation:

1. Calculate the volume of the rectangular prism:

V_1=l*w*h

Where<em> l </em>is the lenght, <em>w</em> is the width and <em>h</em> is the height.

Substitute values.

(You can convert  3 1/4 to decimal by dividing the numerator by the denominator of the fraction and add this to the whole part: 3+0.25=3.25)

Then:

V_1=20in*2in*3.25in=130in^{3}

2. Calculate the volume of a cube:

V_2=s^{3}

Where <em>s</em> is the lenght of any side.

Then:

V_2=(\frac{1}{4}in)^{3}=\frac{1}{64}in^{3}=0.0156in^{3}

3. To calculate the number of cubes that are needed to fill the rectangular prism (which you can call <em>n) </em>, you must divide the volume of the prism by the volume of a cube. Then:

n=\frac{V_1}{V_2}=\frac{130in^{3}}{0.0156in^{3}}=8320 cubes

Suppose y varies jointly as x &amp; z. If y = -180 when z = 15and x = -3,then find y when x = 7 and z = -5. 1 point
sweet [91]

Answer:

y = - 140

Step-by-step explanation:

The statement

y varies jointly as x & z is written as

<h3>y = kxz </h3>

to find y when x = 7 and z = -5 we must first find the relationship between the variables

when y = - 180

z = 15

x = - 3

- 180 = k(15)(-3)

-180 = - 45k

Divide both sides by - 45

k = 4

The formula for the variation is

<h2>y = 4xz</h2>

when

x = 7

z = -5

y = 4(7)(-5)

y = 4(-35)

<h3>y = - 140</h3>

Hope this helps you
