Please help me find the answer !
Answer:
x = 12
y = 6√3
Step-by-step explanation:
✅Apply the intersecting secant theorem to find x. Thus:
6(6 + x) = 7(7 + 8³/7)
Convert the mixed fraction to improper fraction
6(6 + x) = 7(7 + 59/7)
36 + 6x = 49 + 59
36 + 6x = 108
6x = 108 - 36
6x = 72
Divide both sides by 6
x = 72/6
x = 12
✅Apply the tangent-secant theorem to find y. Thus:
y² = 6(6 + x)
Plug in the value of x
y² = 6(6 + 12)
y² = 6(18)
y² = 108
y = √108
y = 6√3

Answer:
"so i need to find e missing side of each right triangle, side c is the hypotenuse!! a = 8.8ft, b= 9ft i have to round the answers to the nearest tenth if necessary "
Step-by-step explanation:
Sure! So remember that the Pythagorean theorem is a squared plus b squared = c squared.
= 8.8 squared + 9 squared = c squared
= 77.44 + 81 = c squared
[tex]\sqrt{158.44}[/tex] = c squared
c squared = (rounded) 12.6 ft
write an equation for the line that is parellel to the given line and that passes through the given point?
y = 2x + 7; (3, 11)
a.y = 2x – 19
b.y=1/2x+5
c.y= -1/2x-5
d.y = 2x + 5
Answer:
y = 2x + 5 (answer d)
Step-by-step explanation:
Parallel lines have the same slope, and thus, if we're given y = 2x + 7, we know that the slope of the 'new' line is 2. This 'new line' passes through (3, 11). Begin with the point-slope formula y - k = m(x - h) and substitute 3 for h, 11 for k and 2 for m:
y - 11 = 2(x - 3)
Rewriting this in slope-intercept form, we get:
y = 2x - 6 + 11. or y = 2x + 5 (answer d)

Devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid. Each side of the base of the pyramid is 6 cm and the height of the pyramid is 9 cm. To get the wax for the candle, Devin melts cubes of wax that are each 4 cm by 4 cm by 4 cm. How many of the wax cubes will Devin need in order to make the candle? Show your work.
The volume of the square pyramid is 6 x 6 x 9/3 = 108 cubic cm.
Volume of the cube = 4 x 4 x 4 = 64 cubic cm
Number of cubes needed: 108/64 = 1 11/16 cubes (1.6875)
Answer:
Solution given:
square pyramid
each side of base[b]=6cm
height[h]=9cm
Volume of square pyramid[V]=[tex] \frac{1}{3 } {b}^{2} h \\ \frac{1}{3} {6}^{2} \times 9 = 108cm ^{3} [/tex]
now
length of cube [l]=4cm
volume of cube[v]=l³=4³=64cm³
now
no of wax needed=[tex] \frac{V}{v} [/tex]=[tex] \frac{108cm³}{64cm³} [/tex]=[tex] \frac{27}{16 } =1\frac{11}{16} [/tex]

Answer:
9. C, II and III.
10. The correct answer is 944 cubic mm, as far as I can tell. I double checked my formulas and calculations. You can copy the formulas/calculations below and email your teacher. I have tried to figure out how they got the numbers they have. The best guess I can come up with is that they used 6 as the diameter of the cylinder, using 3 for the radius. That gets us closer, at 749 cubic mm, but not quite there.
Step-by-step explanation:
9. If the cylinder is standing upright, the horizontal cut would be a circle or oval, and the vertical cut could be a rectangle
10. First we'll get the volume of the base rectangle. Then we'll calculate the volume of a cylinder, then divide that part in half, because it's 1/2 a cylinder on top of a rectangular prism.
Volume of a rectangular prism:
V = (length)(width)(height)
= 11 x 9 x 6 = 594 cubic mm
Volume of a cylinder:
V = (pi)(radius)^2(height)
The radius = 1/2 the diameter of the circle...the diameter is 9, so the radius is 4.5
= (3.14)(4.5)(4.5)(11)
= 699.435
That would be for a full cylinder with radius 4.5 and height of 11. We have half of one, so 699.435/2 = 349.7175 cubic mm
Add the volume of the 1/2 cylinder to the volume of the rectangular prism:
349.7175 + 594 = 943.7175, rounded = 944...which is none of your answers :/

A cyclist travels 5 miles in the direction N 30° E, then travels 3 miles in the direction N 70° E. Which equation measures the cyclist's distance, x, from the starting point?
Answer:
D
Step-by-step explanation:
Edge 2021
The formula calculates the cyclist's separation from the starting point, x, and will be x² = 5² + 3² - 2(5)(3)cos(140°).
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the given information in the question,
From the cos law ;
x² = a² + b² - 2ab cos θ
The values obtained will be,
a =5
b =3
θ = 180° +70° -30°
θ = 180°- 40°
θ = 140°
Substitute the given values in the equation,
x² = a² + b² - 2ab cos θ
x² = 5² + 3² - 2(5) (3) cos(140°)
