Answer:
The given table is
Hours. Earnings per hour.

The rectangle below has an area of x^2-7x+10x square meters and a width of x-5x meters. What expression represents the length of the rectangle?
Answer:
The area of a rectangle is:
\sf A=lw
Plug in what we know:
\sf x^2-7x+10=l(x-5)
Factor the left side:
\sf (x-2)(x-5)=l(x-5)
Divide (x - 5) to both sides:
\sf l=\boxed{\sf x-2}
So the length is x - 2 meters.

x = 11.6
y = 11.6

y= 23.2
x = 18.3
y = 36.6
Answer:
(C)x=11.6, y=23.2
Step-by-step explanation:
Using Theorem of Intersecting Secant and Tangent
Applying this theorem in the diagram, we have:
[tex]TQ$ X TP=TR^2[/tex]
[tex]10(10+x+4)=16^2\\10(14+x)=256\\140+10x=256\\10x=256-140\\10x=116\\$Divide both sides by 10\\x=11.6[/tex]
Next, we apply Theorem of Intersecting Chords
PV X VQ=SV X VR
4 X x= 2 X y
Recall earlier we got: x=11.6
2y=4 X 11.6
2y=46.4
Divide both sides by 2
y=46.4/2=23.2
Therefore: x=11.6, y=23.2

Solve the equation in the interval from 510^\circ510 ∘ 510, degrees to 1050^\circ1050 ∘ 1050, degrees. Your answer should be in degrees. \sin(x)=0sin(x)=0
Answer:
540°, 720° and 900°Step-by-step explanation:
Given equation sin(x) = 0 lying between the interval 510°≤x≤1050°. To find the value of x within this range, we first find the value of from the equation as shown;
sin(x) = 0
taking the arcsin of both sides;
[tex]sin^{-1}(sinx) = sin^{-1} 0\\x = 0^{0}[/tex]
Since x is positive in the first and second quadrant, in the second quadrant, the value of x will be 180°-0° = 180°
Subsequent value of x equivalent to 0° will be addition of 180° to each previous value gotten. The values of x within the range given are as shown
x1 =0°
x2 = 180°-0° = 180(2nd quadrant)
x3 = 180°+180° = 360°
x4 = 360°+180° = 540°
x5 = 540°+180°=720°
x6 = 720°+180° = 900°
x7 = 900°+180° = 1080°
We can see from the values above that the values of x that falls within the given range are 540°, 720° and 900°. This gives the required answers in degrees.

What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
We have to find the volume of a cone with a radius of 3 and a height of 19.
Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.
r=3 and h=19
We have to find the space in the cone with radius 3 and height 19.
The formula for volume of the cone is V=1/3πr²h
We have to plug in the r and h values in formula.
V=1/3×3.14×(3)²×19
=1/3×3.14×9×19
=536.94/3
=179.07 cubic units
Hence, the volume of a cone with a radius of 3 and a height of 19 is 179.07 cubic units.

This net consists of a square and 4 identical triangles. What is the surface area of the solid this net can form?
144 square inches
184 square inches
224 square inches
264 square inches
Answer: C, 224 inches squared
Step-by-step explanation:
When formed into a solid, the triangles are folded upwards to make a pyramid. You can find the surface area by finding the areas of the individual shapes.
There are four triangles with a height of 10 inches and a base of 8 inches.
There is one square with a side length of 8 inches.
Triangle area formula : A = (b * h) / 2
Square area formula: A = s^2
(10 * 8) / 2 = 40
8 ^ 2 = 64
There are four triangles with area of 40 and one square with area of 64.
40 + 40 + 40 + 40 + 64 = 224 inches squared. The correct answer choice is C.
The surface area of the pyramid is 224 in².
What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Given net will form a square pyramid, so we will find the surface area of the square pyramid.
Therefore,
The area of the pyramid = side² + 2 × side × height
= 8² + 2 × 8 × 10
= 64 + 160
= 224
Hence the surface area of the pyramid is 224 in².
