X = 35°
y = 45°


the angle of x is congruent to 35°, meaning their measurements are equal. and to find y, you must remember that all the angles in a triangle sum to 180°. so, you just need to add 35° and 100°, giving you 135°. from there, you subtract it from 180° and get 45°

i hope this makes sense!!

Susan drove 571 miles and the trip took 14 hours of driving time she wants to shorten her driving time by 1/2 hour what average
Allushta [10]

Answer: The answer is 80 mph.


Step-by-step explanation: 1. Divide 14 from 571.

2. You'll get the answer 40. So it's 40 mph.

3. If she's trying to shorten by 1/2 then she should drive 80 mph because if you drive 80 mph it will take 7 hours instead of 14 hours. (She'll go 7 hours because you divide 14 hours by 2. Then you have to multiply 2 to 40.)

PLS HELP THIS IS DUE TOMORROW AND I'M SO DUMB
Vitek1552 [10]
To find a perimeter of any shape you just need to add together all the sides of the shape. 
For example: /_\ (pretend this is a triangle)
If each side of the triangle is 5 cm, then 5+5+5=15 cm (or you can do 5*3=15 cm)
The perimeter of the triangle is 15 cm. 

Hope I helped!(:

The ratio of sides of 2 similar cubes is 3:4. Larger cube has a volume of 1728 cubic meters. What is the volume of the smaller c
Bond [772]

Answer:

See steps

Step-by-step explanation:

Volume of cubes is proportional to the cube of the side length.

Using proportions,

Volume of smaller cube / 1728 = (3/4)^3

Cross multiply,

Volume of smaller cube

= 1728 * (3/4)^3

= 1728 * (27/64)

= 729 cubic metres.

Note: all cubes are similar and each has 6 congruent faces.

PLEASE HELP
densk [106]

For this case we have that by definition, a function is of the form:

y = f (x)

So, we have the following system of equations:

y = -6x + 2\\y = -2x + 4

Equating the equations we have:

-6x + 2 = -2x + 4

Adding 2x to both sides of the equation:

-6x + 2x + 2 = 4\\-4x + 2 = 4

Subtracting 2 from both sides of the equation:

-4x = 4-2\\-4x = 2

Dividing between -4 on both sides of the equation:

x = \frac {2} {- 4}\\x = - \frac {1} {2}

Thus, the value of the variable "x" is -0.5.

Answer:

-0.5
