Answer:
b.) 9 log7 x - 3 log7 Y
Step-by-step explanation:
[tex] log_{7}\bigg( \frac{ {x}^{3} }{y} \bigg)^{3} \\ \\ = 3log_{7}\bigg( \frac{ {x}^{3} }{y} \bigg) \\ \\ = 3log_{7} {x}^{3} - 3log_{7}y \\ \\ = 3 \times 3log_{7} {x} - 3log_{7}y \\ \\ = 9log_{7} {x} - 3log_{7}y \\ \\ [/tex]

The figure is made up of 2 cones and a cylinder. The cones and
cylinder have a 4 cm diameter.
What is the exact volume of this figure?
отпCm3
0 12cm
0 207cm
0 367cm
Answer:
This question is unsolvable because:
1) Volume can't be measured in cm (think you mean cm^3)
2) Volume of the cylinder is calculated with its height and bottom area.
We can calculate its bottom area like this: (4/2)^2*pi
But since we do not know the cylinder nor the cones' height then we can't
calculate their volume.
Please correct me if im wrong
The circumference of a circle is approximately 3.14 times the length of its diameter. Which inequality can be used to find all possible diameter lengths, d, if the circumference of a circle is more than 50 cm?
Answer:
3.14d > 50 cm
Step-by-step explanation:
Given that the circumference of a circle is approximately 3.14 times the length of its diameter
If the circumference is C and the length of the diameter is d then
C = 3.14d
If the circumference of a circle is more than 50 cm then
3.14d > 50
The inequality can be used to find all possible diameter lengths, d,
d > 50/3.14
d > 15.92cm

Kristin spent $120 on shirts. Fancy shirts cost $35 and plain shirts
cost $10. If she bought a total of 7 then how many of each kind did
she buy?
Answer:
2 fancy shirts
5 plain
Step-by-step explanation:
2 fancy- 70$
5plain- 50$
50+70=120
Answer:
she bought 2 fancy shirts, and 5 plain shrits.
Step-by-step explanation:
$35×2=$70 (for the fancy shirts so she bought 2 fancy shirts)
Now, we have 5 shirts left that she bought so they must be plain shirts. to check, we would multiply $10×5=$50, then we would add $70(from the fancy shirts) and $50 (from the plain shirts) and get a total of $120.
I hope this helps!

principal is 5000 rate p.a. is 8 percent and time 1year
Answer:
5400
Step-by-step explanation:
Given data
P= 5000
r= 8%
t= 1 year
The simple interest expression is given as
A= P(1+rt)
Required
The final amount A
substitute
A= 5000(1+0.08*1)
A= 5000*1.08
A= 5400
Hence the final amount 5400
Diego scored 9 points less then Andre in the basketball game.Noah scored twice as many points as Diego.if Noah scored 10 points , how many points did Andre score
Answer:
14 points.
Step-by-step explanation:
To solve this problem, let's make an equation.
Let x represent the unknown number, or the amount of points Andre scored.
We know that Noah scored 10 points.
Noah scored twice as many points as Diego, therefore Diego must've scored 5 points, because 5 * 2 = 10.
So, if Diego scored 9 points less than Andre, and we know that Diego scored 5 points, then the equation we are left with is
x - 9 = 5
To solve, just add 9 to both sides.
x - 9 + 9 = 5 + 9
We are left with:
x = 14
So, Andre scored 14 points.

find an equivalent expression for the missing side length of a rectangle. then find the missing side length when x=3. round to the nearest tenth of an inch.
Answer:
first find the length of trangel using
h^2=p^2+b^2
Equivalent expression for the missing side length of a rectangle is [tex]\sqrt{60} x[/tex]
The missing side length when x =3 is 23.2 inch
Rectangle :In a rectangle , opposite sides are equal . The vertex of rectangle is right angle . The diagonal of rectangle forms a right angle triangle.
Given the width of the triangle is 2x. The diagonal of triangle is 8x inches
Let 'L' be the length of the rectangle
To find out the expression for the length of the triangle use pythagorean theorem
hypotenuse ^2=length ^2 + width ^2
[tex](8x)^2=L^2+(2x)^2\\64x^2+4x^2+L^2\\64x^2-4x^2=L^2\\60x^2=L^2\\L =\sqrt{60x^2}\\ L=\sqrt{60}x[/tex]
An equivalent expression for the missing side length of a rectangle
[tex]\sqrt{60} x[/tex]
find the missing side length when x=3
Substitute 3 for x
[tex]L= \sqrt{60} x\\L =\sqrt{60}(3)\\L= 23.2 inch[/tex]

(4x – 6)°
(2x)
Equation:
X:
Answer:
x=31
Step-by-step explanation:
2x+4x-6=180
6x=180+6
6x=186
x=31
Answer:
x = 31
Step-by-step explanation:
2x and 4x - 6 are alternate angles and supplementary, sum to 180°, then
2x + 4x - 6 = 180
6x - 6 = 180 ( add 6 to both sides )
6x = 186 ( divide both sides by 6 )
x = 31
