X= 17.5

Step-by-step explanation:

the outside of the triangle always = 180

so you need to add up all the sides and equal to 180

5x+35+x+5+2x=180

add like terms

8x+40=180

get the x alone

x=17.5

The graph of f(x) = 2x + 3 shifts 10 units to the right when it is replaced with the graph of f(x) = 2x − k. What is the value of k?

Answers

Answer:

k=7

Step-by-step explanation:

when entering values of x in the function, it is observed that for k = 7 the results of f (x) displace 10 units. For this see the attached table. Therefore, for this case, the correct answer is k = 7 and the way to solve it is to substitute values of x in the given functions and see the results of f (x).I attach results.

What is the degree-measure of an angle travelled by the minute hand from 3:05pm to 3:50pm?

Answers

Answer:

270°

Step-by-step explanation:

We know that a full circle is 360°, the shape of a clock, and that the clock is divided into 12 different sections.

Our equation would be: 360 ÷ 12 = 30

3:05 is at the 1 hand and 3:50 is at the 10 hand. Subtract 1 from 10 and you get 9.

9 · 30 = 270, so our angle is 270°

An art teacher needs to cut out squares of paper for an art project from a left-over sheet of paper measuring 72 x 104 inches. What size would the biggest possible square be with sides of whole number length?

Answers

Answer:

7488 inches

Step-by-step explanation:

I think that this is the correct answer. The reason is that you have to multiply 72 x 104. I´m not 100% sure.

The required maximum area of the biggest possible square is with sides of a whole number length of 7396 inches².

What is surface area?

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Here,
Area of the leftover sheet = 72  × 104 = 7488 inches²

area of the square = 7488
a² = 7488
a = 86.53

Somehow, for  the biggest possible square to be with sides of whole number length,
The area is given as,
= 86²
= 7396 inches²

Thus, the required maximum area of the biggest possible square be with sides of whole number length  7396 inches².

a can't be an integer

-√18/√2 = -√(3*3*2)/√2 = -3(√2)/√2 = -3

At best you will get 4√2 - 3

a = 4√2

b = - 3

b is correct. the answer for b = -3

In ABC the measure of the largest angle 32 less than 3 time the smallest angle the measure of the middle angle is 8 more than half the measure of the largest angle . What is the measure of the middle angle?

Answers

Answer: The measure of the middle angle = 52°

Step-by-step explanation:

Let x = Smallest angle.

largest angle = [tex]3x-32[/tex]

Middle angle= [tex]8+\dfrac12 (3x-32)[/tex]

Sum of all angles in a triangle is 180 degrees.

So, Smallest angle+ largest angle+ Middle angle = 180°

[tex]\Rightarrow\ x+8+\dfrac12 (3x-32)+3x-32=180\\\\\Rightarrow\ 4x-24+\dfrac{3x}{2}-16=180\\\\\Rightarrow\ \dfrac{2\times4x+3x}{2}-40=180\\\\\Rightarrow\ \dfrac{11x}{2}-40=180\\\\\Rightarrow\ \dfrac{11x}{2}=220\\\\\Rightarrow\ x=\dfrac{220\times2}{11}\\\\\Rightarrow\ x= 40[/tex]

Now , Middle angle= [tex]8+\dfrac12 (3(40)-32)=8+\dfrac12 (120-32)[/tex]

[tex]=8+\dfrac12 (88)\\\\=8+44\\\\=52[/tex]

Hence, the measure of the middle angle = 52°
