Using: A^2+b^2=c^2

A&b= (√10)^2=10

10+10=c^2

20=c^2

(take the square root of 20)

c=2√5

Your answer is D

The answer for this question is D, 2\sqrt{5}

We can see that this triangle is a right triangle (because of the box on one of it's angles). In a right triangle, we know that, with a and b being the legs, and c being the hypotenuse, that a² + b² = c². In this case, x is the length of the hypotenuse and \sqrt{10} is the value of both legs.

\sqrt{10}² = 10, and x² = x², meaning that

10 + 10 = x²

x² = 20

To find what x is equal to, we take the positive square root of 20 (the length of a side can't be negative).

x = \sqrt{20}

Now, we can simplify. \sqrt{20} = \sqrt{2²*5} (that's the prime factorization). But, since we see the number 2 two times in this square root, we can factor it out. The simplified form of our answer is:

2\sqrt{5}

Write the slope-intercept form of the equation of the line that passes through (-3,1) and is parallel to the line represented by
Shalnov [3]
 assume you want a line that goes through the given point and parallel to the given line. A line that is parallel to y=2/3 x + 5 will have the same slope. slope of that line is 2/3...the number in front of the x. So our new line will have slope of 2/3. now we need the y-intercept. To find that start with a slope intercept equation y=mx+b plug in the slope that we already know...it goes in for x...will be the number in front of x y= 2/3 x + b. now all we need is a number to plug in for the "b" and we will have it. to get the "b"...start with the part you already know. y = 2/3 x + b use the point they gave you...(-3,1)...and get x and y from it x will be -3 and y will be 1 plug that in 1= 2/3 ( -3) + b now we solve for b 1 = -2 + b 3 = b now we have the b we need y = 2/3 x + b y = 2/3 x + 3

suppose A and B are complementary angles, m a =(3x+5) and m b= (2x-15). Solve for x and then find m a and m b
vlada-n [284]
2 angles are complementary if the sum of their measures is 90°.

For example  if m(P) = 41°  and m(Q)=49°, then P and Q are complementary.


Thus A and B are complementary means that m(A)=m(B)=90°:

(3x+5°) + (2x-15°) =90°

5x-10°=90°

5x=100°

x=20°



Thus 

m(A)=3x+5°=3* 20°+5°=60°+5°=65°

m(B)=2x-15°=2*20°-15°=40°-15°=25°

Please help! Correct answers only please! The M&M jar has a square base with a length and width of 7 cm and a height of 6.5
Tcecarenko [31]

Answer: a) 100

<u>Step-by-step explanation:</u>

Volume (V) of the prism = Length(L) x width(w) x height(h)

V = 7 x 7 x 6.5

   = 318.5 cm³

Next, what is the volume of an M & M? The info isn't given so according to the internet it is 0.636 cm³

\text{Quantity}=\dfrac{\text{Volume of the prism}}{\text{Volume of an M}\ \&\ \text{M}}}=\dfrac{318.5}{0.636}=\large\boxed{500}

The nearest answer to this is: (a) 100

because the upper limit cannot be 10,000

If the line formed by equation 1 is parallel to the line formed by equation 2, fill in the missing value below.
madreJ [45]

Answer:

y =-\frac{3}{2}x + 6

Step-by-step explanation:

Given

y = []x + 6 --- equation 1

y = \frac{2}{3}x + 10 --- equation 2

Required

Fill in the blank

A linear equation is represented as:

y = mx + b

Where m represents the slope

If (1) and (2) are perpendicular, then:

m_1 = -\frac{1}{m_2}

In y = \frac{2}{3}x + 10 --- equation 2

m_2 = \frac{2}{3}

So, we have:

m_1 = -\frac{1}{m_2}

m_1 = -\frac{1}{2/3}

m_1 = -\frac{3}{2}

Hence, the complete equation is:

y =-\frac{3}{2}x + 6
