Answer:
Answer is A. 3 + 1.5 b < 15.
Step-by-step explanation:
Look at the problem carefully. Variable (b) represents books, and it states that the books weigh 1.5 lbs each. So you add her lunch (1 lb) and her shoes (2 lbs) to get 3 lbs. Once you add it together, it's less than (<) 15 lbs.
I tried to make this as understandable as possible, hope it helps.

Answer:
1. 8820.26 yds^2
2. 101.265 m^2
Step-by-step explanation:
For both problems you need to use the equation π*r^2 which is the area of a circle and where r is the radius of the circle. The radius is also equal to 1/2 the diameter so using this we can figure out the are of the first circle
For the second problem we have to find the area of the circle with and without the sidewalk around it and subtract them from each other

Use matrices to determine the coordinates of the vertices of the rotated figure. Then graph the pre-image and the image of the same coordinate grid. Rot90 for UVW with vertices U(-4, 7), V(5, 4), and W(5, -5).
Answer:
The answer is A
Step-by-step explanation:
just got it right on edge :)
The images of the points are U' (-7, -4), V' (-4, 5), W' (5, 5)
What is Rotation?A rotation is a type of transformation that rotates each point in a figure a specific number of degrees around a particular point.
90° clockwise rotation: (x,y) becomes (y,-x) 90° counterclockwise rotation: (x,y) becomes (-y,x) 180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y) 270° clockwise rotation: (x,y) becomes (-y,x)When we rotate a point around the origin by 90° clockwise or anti-clockwise, (x,y) becomes (y,-x) .
- Then matrix of the rotation 90° is
[tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex]
We have the point U (-4, 7) and its image is
U' =[tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}-4\\7\end{array}\right][/tex]
U' = [tex]\left[\begin{array}{ccc}-7\\-4\end{array}\right][/tex]
and, point V is (5, 4) and its image is
V' = [tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}5\\4\end{array}\right][/tex]
V' = [tex]\left[\begin{array}{ccc}-4\\5\end{array}\right][/tex]
and, point W is (5, -5) and its image is
W' = [tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}5\\-5\end{array}\right][/tex]
W' = [tex]\left[\begin{array}{ccc}5\\5\end{array}\right][/tex]
So, The images of the points are U' (-7, -4), V' (-4, 5), W' (5, 5)

In the triangle shown below, find the value of a.
45°

I don’t get this someone pleas help out!
Given:
The figure of a right angle triangle.
Measure of one angle is 45 degrees.
Hypotenuse = [tex]9\sqrt{2}[/tex]
Opposite side of angle 45 degrees = a
To find:
The value of a.
Solution:
In a right angle triangle,
[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]
It can be rewritten as:
[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]
For the given triangle,
[tex]\sin (45^\circ)=\dfrac{a}{9\sqrt{2}}[/tex]
[tex]\dfrac{1}{\sqrt{2}}=\dfrac{a}{9\sqrt{2}}[/tex]
[tex]\dfrac{9\sqrt{2}}{\sqrt{2}}=a[/tex]
[tex]9=a[/tex]
Therefore, the value of a is 9 units.

Find the measure of \angle G∠G. Round your answer to the nearest tenth (one decimal place).
Hi there!
[tex]\large\boxed{G \approx 55.44^{o}}[/tex]
To solve, we can use right triangle trigonometry.
Recall that:
sin = O/H, cos = A/H, tan = O/A.
For angle G, HF is its OPPOSITE side, and FG is the hypotenuse.
Therefore, we must use sine to evaluate:
sinG = 14 / 17
sin⁻¹ (14/17) = ∠G. Evaluate using a calculator.
∠G ≈ 55.44°
Which solid of revolution is produced by rotating the shape below 360° about the given axis?
Explanation:
When we rotate a rectangle around an axis of symmetry, we end up with a cylinder. Think of a revolving door or a turbine. The flat door moves through 3D space to produce or carve out a 3D cylinder.
This figure is composed of two rectangles, so we'll end up with two cylinders. They will both share the same center, so we'll have a sideways two-layer wedding cake structure when everything is said and done. This points to choice A as the final answer.
The solid of revolution, which is produced by rotating the shape below 360° about the provided axis, is the first one. Option A is correct.
What is solid of revolution?Solid of revolution is the method to obtain the solid figure by the plane. When a plane is revolving about an axis, a solid figure is obtained whose shape is depending on the shape of the plane.
In the problem,
A plane is given which is in the elbow shape. The axis around which it has to revolve is horizontal.The plane is kept at this axis from the base of it.The solid generated with this plane is full rotation, and it will look like the stand of the pole.
Thus, the solid of revolution, which is produced by rotating the shape below 360° about the provided axis, is the first one. Option A is correct.

The money Mr. Jarod earns, m, varies directly with the number of haircuts he gives, h. He earns $15 for five haircuts. Which equation represents his earnings for the job?
Answer:
m/h = k
Step-by-step explanation:
Money earned = m
Number of haircuts = h
m α h
m = kh
k is the constant of proportionality
Amount earned for 5 hair cuts = 15
n = 5 ; m = 15
Earning for the job = k
From m = kh
Divide both sides by h
m / h = kh/h
m/h = k
15/5 = 3
Earning for the job = $3

Capillaries - Enable the actual exchange of water and chemicals between the blood and the tissues. They are the smallest and thinnest of the blood vessels in the body and also the most common. Capillaries connect to arterioles on one end and venules on the other.
The thin walls of the circulatory system allow oxygen and nutrients to pass from the blood into tissues.
