Answer:

first one

relationship between base and perpendicular is

given by tan angle

tan x=P/h

remember perpendicular is opposite side of taken angle

tan x=13/8

<x=tàn-¹(13/8)=58.39°

for second one

relationship between base and hypotenuse is given by cos angle

cos G=b/h

cos G=24/32

<G=cos-¹(24/32)=41.4 is your answer

Valeria purchases a can of chicken noodle soup and a can of tomato soup. The can of chicken noodle soup has a height of 4 inches
sweet [91]

Answer:

The height of the tomato soup can is 2.6 in.

Step-by-step explanation:

"The can of chicken noodle soup has a height of 4 inches and a radius of 2 inches."

We can find the volume of this can.

V = pi r² h

V = 3.14 * (2 in.)² * (4 in.)

V = 50.24 in.³

"The can of tomato soup has the same volume, but a radius of 2.5 inches."

Now we know the volume of the can, so we can find the height, h.

V = pi r² h

50.24 in.³ = 3.14 * (2.5 in.)² * h

50.24 in.³ = 19.625 in.² * h

h = (50.24 in.³)/(19.625 in.²)

h = 2.56 in.

Answer: The height of the tomato soup can is 2.6 in.

What is 6.79 minus 3.95 rounded to, to the nearest half dollar
likoan [24]
$6.79 - $3.95 = $2.84. Since you’re rounding to the nearest half dollar, you’d found to $3. $2.84 is closer to $3 than $2.50

$3 - $2.84 = $.16
$2.84 - $2.5 = $.34

A cuboid has a length of 25cm, a width of 5cm and height of (x-2)cm
mr Goodwill [35]

Step-by-step explanation:

Hi there!

From above question;

A cuboid has a length of 25cm, a width of 5cm and height of (x-2)cm.

Length (l) = 25cm

width (b) = 5cm

height (h) = (x-2)cm.

a).

Volume= l*b*h

V = 25*5*(x-2)

V = 125(x-2)

V = 125x - 250 → Answer

b).

(i)

V = 750cm³

V = 125x - 250

750 = 125x - 250..........(i)

(ii)

The equation (i) is: 750 = 125x - 250

or, 125x = 750+250

or, 125x = 1000

or, X = 1000/125

Therefore, X= 8cm.

(iii)

Height (h) = x-2

= 8-2

= 6

Therefore, height is 6cm.

<u>Hope</u><u> it</u><u> helps</u><u>!</u>
