Answer:
150
Step-by-step explanation:
add 79+ 71 because you rounded to get that number then add :)
150
When estimating you just round off the numbers so, 78.9 becomes 79 and 71.2 becomes 71 so, 79 + 71 = 150.

Will Give Brainliest if Correct
Answer:
(a) 0
(b) -3/26
Step-by-step explanation:
(a)
We essentially plug 1 in for x and 2 in for y.
Our expression is [tex]\frac{2x-y}{y^2+1}[/tex], so making the correct substitutions yields:
[tex]\frac{2x-y}{y^2+1}=\frac{2*1-2}{2^2+1}=\frac{2-2}{4+1} =\frac{0}{5} =0[/tex]
So, the answer for part (a) is 0.
(b)
Again, we're now plugging in 1 for x and 5 for y:
[tex]\frac{2x-y}{y^2+1}=\frac{2*1-5}{5^2+1}=\frac{2-5}{25+1} =\frac{-3}{26} =-\frac{3}{26}[/tex]
So, the answer for part (b) is -3/26.
Step-by-step explanation:
So we have the rational expression [tex]\frac{2x -y}{y^{2} +1}\\[/tex]. All we have to do is to just plug the given values for what x and y are.
Solution of a:[tex]\frac{2x -y}{y^{2} +1}\\ \frac{2(1) -(2)}{(2)^{2} +1} \\ \frac{2 -(2)}{4+1} \\ \frac{0}{5} \\ 0[/tex]
Answer of a:[tex]0[/tex]
Solution of b:[tex]\frac{2x -y}{y^{2} +1}\\ \frac{2(1) -(5)}{(5)^{2} +1} \\ \frac{2 -(5)}{25+1} \\ \frac{-3}{26} \\ -\frac{3}{26}[/tex]
Answer of b:[tex]-\frac{3}{26}\\[/tex]

Hummingbirds beat their wings very fast. The smaller the
hummingbird is, the faster its wings beat. The average hummingbird beats its
wings about 3 x 10 3 times a minute. How many times a minute is that, written as
a whole number?
Pls help me! I will give brainliest
Answer:
A hummingbird's heart beats from 225 times per minute when it's at rest and more than 1,200 times per minute when it is flying. Its wings beat about 70 times per second in regular flight and more than 200 times per second while diving.

Step-by-step explanation:
Determine the height of the triangle if the area is 24 square inches and the base is 12 inches.
Answer:
4
Step-by-step explanation:
We use 1/2base times height to find the area and since we already have an area we just do 24= 6h then we divide 6 on both sides and height equals 4
Answer: 6 inches
Step 1: Subtract 12 because 12 iches is the base.
24 - 12 = 2
Step 2: Divide 12 by 2 because triangles have two equal sides.
12 ÷ 2 = 6
Answer = 6

A parabola has a vertex of (-2,1) and passes through the point (0,-7). What is the value of amplitude
Answer:
The value of the amplitude is -2
Step-by-step explanation:
The given parameters are;
The vertex of the parabola = (-2, 1)
The point through which the parabola passes = (0, -7)
The equation of the parabola can be expressed as follows;
y - y₀ = a·(x - x₀)²
Where;
y₀ = The y-coordinate of the vertex = 1
x₀ = The x-coordinate of the vertex = -2
Therefore, we substitute the known values of the coordinates of a point the parabola to get;
-7 - 1 = a·(0 - (-2))²
-8 = 4·a
a = -8/4 = -2
The value of the amplitude a = -2.

I need help please it’s a test and I don’t understand
Answer:
to get x look at that triangle that it is in I know the angles in a triangle add up to 180° so it will be 180 - 63 degrees plus 36 degrees then to get z it will be 36 + 63 because interior angles add up to one exterior angle then to get y addz + 13 degrees then subtract it from 180°

what is 300 × = 120,000
there is nothing between the × and = cuz its asking me 300× what = 120,000.
The answer is 400
First, you must flip the equation.
[tex]120000[/tex] ÷ [tex]300[/tex] = ?
Then, you must simplify the equation.
[tex]1200[/tex] ÷ [tex]3[/tex] = ?
Finally, divide the two terms.
[tex]1200[/tex] ÷ [tex]3[/tex] = 400

Write the equation in vertex form using the following information: vertex (4, -6) and a=1.
Submit
Answer:
y = (x - 4)² - 6Step-by-step explanation:
An equation of a quadratic function in a vertex form is y=a(x-h)²+k, where vertex is (h, k)
vertex (4, -6) means h = 4 and k = - 6
So:
y = 1(x - 4)² + (-6)
y = (x - 4)² - 6
