Find the following value

e-lub [12.9K]

Answer:

∠ BCA = 45°, ∠ AWD = 90°

Step-by-step explanation:

All angles are right angles by definition.

Diagonals bisect the angles , so

∠ BCA = 45°

Diagonals are perpendicular bisectors of each other, so

∠ AWD = 90°

George Kittle was given 300 protein bars. He eats 4 of them every day. Write an equation that represents the situation if he has

nikklg [1K]

Answer:

Part 1) The linear equation is $y=-4x+300$

Part 2) if he has 90 protein bars left, then 52.5 days have passed

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

y is the number of protein bars left

x is the number of days

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

The slope is equal to

$m=-4\ \frac{bars}{day}$ ----> is negative because is a decreasing function

$b=300\ protein\ bars$

substitute

$y=-4x+300$ ---> linear equation that represent this situation

If he has 90 protein bars left

so

For y=90

substitute in the linear equation and solve for x

$90=-4x+300\\4x=300-90\\4x=210\\x=52.5\ days$

therefore

if he has 90 protein bars left, then 52.5 days have passed

The base of a triangle is 9/4 times of its height. If the area of triangle is 144 cm2. Find the height and the base.

Mazyrski [523]

Step-by-step explanation:

Given that the base of triangle is 9/4 times of its height . And area is 144 cm² . Let the height be h , then its base be 9h/4 .

<u>•</u><u> </u><u>Acco</u><u>rding</u><u> </u><u>to</u><u> </u><u>Question</u><u> </u><u>:</u><u>-</u><u> </u>

$\tt\to Area_{(\triangle)}=\dfrac{base\times height}{2}\\\\\tt\to 144cm^2 = \dfrac{9h\times h}{4\times 2 } \\\\\tt\to h^2 =\dfrac{12\times 12 \times 2 \times 2 }{3\times 3 }\\\\\tt\to h =\sqrt{\dfrac{12\times 12 \times 2 \times 2 }{3\times 3 }}\\\\\tt\to h =\dfrac{(12)(2)}{3} \\\\\tt\to \boxed{\orange{\tt h = 8 cm }}$

Therefore ,

Height = h = 8cm .
Base ,= 9h/4 = 18cm .
