Answer:
8.3
Step-by-step explanation:
8 square = 6 square + x square
square them
64 = 36 + x square
minus 64 with 36
64 - 36 = 28
cancel the square with square root
x square = 28
square root of 28 is 5.3
5.3 x 5.3 = 28.09

Answer:
254.34 mm²
Step-by-step explanation:
Diameter (d) = 18 mm
Radius (r) = d/2 = 18/2 = 9 mm
π = 3.14
Area of the circle
= πr²
= (3.14)(9)²
= 3.14 × 81
= 254.34 mm²
____________
Hope it helps ⚜
diameter= 18mm
to find:the area of the circle
solution:[tex]area = \frac{1}{4} \pi {d}^{2} [/tex]
[tex]a = \frac{1}{4} \times \pi \times {18}^{2} [/tex]
[tex]a = 254.469 \: {mm}^{2} [/tex]
hence, the area of the circle is 254.469 square millimeters.
The volumes of two similar figures are given. The surface area of the larger figure is given. Find the surface area of the smaller figure.
V=648 m^3
V=1536 m^3
S.A.=864 m^2
Step-by-step explanation:
the volume of a figure bases always on a calculation that multiplies 3 dimensions.
while a surface area bases always on a calculation that multiplies 2 dimensions.
since the figures are similar, that means that all dimensions or side lengths of one figure correlate to the corresponding dimensions or side lengths of the other figure via the same scale factor f.
and that means that
large side length = small side length × f.
and that means that f has to be multiplied in 3 times for the volume and 2 times for the surface area (once for every dimension).
so,
large volume = small volume × f × f × f =
= small volume × f³
1536 = 648 × f³
f³ = 1536/648 = 64/27
f = 4/3
and
large surface = small surface × f×f =
= small surface × f²
small surface = large surface / f² = 864 / 16/9 =
= 864 × 9/16 = 54 × 9 = 486 m²

SM 4 - 7 A shoe store marks up
its merchandise by 8%. What is the
selling price of a pair of shoes
whose wholesale price was
$34.50?
Assuming $34.50 is the price after the 8% price increase, we can set up this equation (if 34.50 is the old price, scroll down):
34.50=[tex]\frac{108}{100} x[/tex]
Where x ( or 100/100 x) is the original price.
We can simply the fraction, or just multiply by 100 on both sides.
3450=108x
x=31.9444 (4 repeating).
If the old price is 34.50, then we can set up this equation:
34.50+ [tex](\frac{8}{100} *34.50)[/tex] = x
34.5 + 2.76 = x
x = 37.26
The new selling price would be $37.26.
A company collects data on its employees. It finds that
. 20% of employees in each department are part-time,
80% of employees in each department are full-time, and
• each of the company's four departments has 45 employees.
How many part-time and full-time employees does the company have?
Answer:
9 Part-time employees
36 full-time employee
Step-by-step explanation:
20% multiply by 45 = 9
80% multioly by 45 =36
therefore to check if your answers are correct add 9 + 36 which gives you 45, the total number of employees in each company's four department.
Answer:
The company has 144 full-time employees and 36 part-time employees.
Step-by-step explanation:
The company has 144 full-time employees and 36 part-time employees because you have to do .20*45 to get 9 part-time employees per department. Then you can do 45-9 to get 36 full-time employees per department or you can do .8*45, either way is fine. Then you have to multiply 36 by 4 and 9 by 4 to get 144 full-time employees and 36 part-time employees.
What is the explicit formula for this sequence?
-6, -2, 2, 6, 10, ...
Answer:
4n-10, Answer is D
Step-by-step explanation:
First we will use n as any number.
the difference between each of the numbers is +4
This creates first part of the formula.
4n...
If you do 4n and replace n as one (For the first number of the sequence) then 4×1=4. You then have to find out how much you need to add or subtract to get -6 so the difference between 4 and -6 is -10.
This creates the second part of our formula.
4n - 10
You can check this by doing the same thing for the second number and replacing n with 2.
2×4=8
8 - 10= -2 which is the second number in the sequence which confirms this is correct.

Answer:
PQ = 15M = (8.5, 8)Step-by-step explanation:
Given points P(4, 2) and Q(13, 14), you want the length of PQ and its midpoint.
(a) LengthThe length of PQ is given by the distance formula ...
d = √((x2 -x1)² +(y2 -y1)²)
d = ((13 -4)² +(14 -2)²) = √(9² +12²) = √225
d = 15
The length of PQ is 15 units.
(b) MidpointThe midpoint is halfway between the end points. It is conveniently found as the average of the coordinates of the end points.
M = (P +Q)/2
M = ((4, 2) +(13, 14))/2 = (4+13, 2+14)/2 = (17, 16)/2
M = (8.5, 8)
The midpoint of PQ is M(8.5, 8).
__
Additional comment
The length of PQ is the hypotenuse of a right triangle with side lengths 9 and 12 units. You recognize this ratio as 3:4, so the triangle is a 3-4-5 right triangle, scaled up by a factor of 3. The length PQ is 3·5 = 15.
{3, 4, 5} is one of several Pythagorean triples commonly seen in textbook problems. Others include {5, 12, 13}, {7, 24, 25}, {8, 15, 17}.

How many years will it take an account to double in value, assuming a 5.2% interest rate compounded quarterly? Round your answer to the nearest tenth.
The money account is doubled at an interest rate of 5.2 % compunded quarterly, that is, under the model of compound interest in a time period of about 3.5 years.
How to determine the doubling time of money account
The compound interest takes into account the change of money deposited in time in contrast with the simple interest, which only takes the initial amount of money into account. Please notice that four quarters equals a year.
The compound interest formula is described below:
C = C' · (1 + r/100)ⁿ (1)
Where:
r - Interest raten - Number of periodsC' - Initial money amountC - Current money amountIf we know that C = 2 · C' and r = 5.2, then the doubling time is:
n = /㏒ C/C'/㏒ (1 + r/100)
n = ㏒ 2/㏒ 1.052
n ≈ 13.674
The money account is doubled at an interest rate of 5.2 % compunded quarterly, that is, under the model of compound interest in a time period of about 3.5 years. [tex]\blacksquare[/tex]

Answer:
136
Step-by-step explanation:
First you multiply 7•5 which is 35, and sense there is 2 squares with that unit, you multiply 35•2 which is 70. After that you get the middle value by multiplying 6•7, which is 42. Then you add 42+70, and that's 112. Now you have to find the area of the triangle, so you multiply 6•4, and that's 24, but sense there are 2 of them with the same unit you don't need to divide by 2. Then after that you add 112+24 and the total area is 136
Answer:
136 square units
Step-by-step explanation:
A "net" is a map of the surfaces of the prism. If you cut it out and fold along the solid lines, you can shape it into the triangular prism it represents. The area of the net is the area of the prism.
As with any composite figure, its area can be found by decomposing it into parts whose area formulas you know. Here, the net can be cut along the horizontal lines to form a rectangle and two triangles.
__
rectangleThe rectangle has an overall length of 5+6+5 = 16 units, and a width of 7 units. Its area is ...
A = LW
A = (16)(7) = 112 . . . . square units
trianglesEach triangle has a base of 6 units and a height of 4 units. Its area is ...
A = 1/2bh
A = 1/2(6)(4) = 12 . . . . square units
total areaThe composite figure shown has been decomposed into one rectangle and two triangles, so its total area is ...
rectangle area + 2 × triangle area
= 112 + 2×12 = 136 . . . . square units
The surface area of the triangular prism is 136 square units.
