The perimeter of the scalene triangle is 54.6 cm.
*pretend this is the triangle
3a, a b
Which equation can be used to find the value of b if side a measures 8.7 cm?
A. 8.7 + b = 64.6
B. 17.4 + b = 54.6
C. 21.6 + b = 54.6
D, 34.8 + b =54.6
Answer:
D, 34.8 + b =54.6
[tex]perimeter = s + s + s \\ 54.6 = 3a + a + b \\ 54.6 = 4a + b \\ (4 \times 8.7) + b = 54.6 \\ 34.8 + b = 54.6[/tex]
Mark has 10 pens. Kate has 5 times as many pens as Mark.
Which equation below answers how many pens Kate has? (y = number of Kate's pens
10 = 5 × y
10 = 5 + y
y = 5 × 10
y = 10 ÷ 5
Answer:
The third one, y = 5 x 10
Step-by-step explanation:
y = number of Kate's pens, 5 = how many times more pens Kate has than Mark, and 10 = how many pens Mark has.

which of the folowing could be the equation for a parabola that opens to the left with vertex (-17, 2)
Answer:
x = a(y+17)^2 + 2 where a < 0
Step-by-step explanation:
Since the parabola is horizontal, the formula of the parabola is x = a(y-h)^2 + k where (h,k) is the vertex.
Since it opens to the left, a must be negative. The vertex is (-17, 2), so h = -17 and k = 2.
Substituting these in, we find that the equation is
x = a(y+17)^2 + 2 where a is a real number that is less than 0 (i.e. negative)

Aan angle in quadrant I, the value of sin[tex]\theta[/tex] is [tex]\rm Sin \theta=\dfrac{\sqrt{14} }{5}[/tex].
What is the sin theta?Sin theta is defined as the ratio of perpendicular and hypotenuse.
The given equation is;
[tex]\rm Cos\theta=\dfrac{\sqrt{11} }{5}[/tex]
The cos[tex]\theta[/tex] is given by;
[tex]\rm Cos\theta=\dfrac{Base}{hypotenuse}[/tex]
By applying Pythagoras theorem the value of base is;
[tex]\rm (5)^2=Perpendicular^2+ (\sqrt{11} )^2\\\\ Perpendicular^2= 25-11\\\\ Perpendicular^2=14\\\\ Perpendicular =\sqrt{14}[/tex]
The value of sin[tex]\theta[/tex] is;
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypoteunse}\\\\Sin \theta=\dfrac{\sqrt{14} }{5}[/tex]
Hence, the value of sin[tex]\theta[/tex] is [tex]\rm Sin \theta=\dfrac{\sqrt{14} }{5}[/tex].

give the answer in cm^2
p.s the answer is not 66
Answer:
45 cm^2
Step-by-step explanation:
area of the figure
split the figure and form to figure rectangle and square
for rectangle
length = 6 cm + 3 cm
=9 cm
breadth = 4 cm
area of rectangle = l*b
=9 cm * 4 cm
=36 cm^2
for square
length =3 cm
area of square = (3 cm)^2
=9 cm^2
area of figure = area of rectangle + area of square
=36 cm^2 + 9 cm^2
=45 cm^2
Một ủy ban an toàn kiểm tra ngẫu nhiên 900 công nhân xây dựng trong thời gian làm việc, thấy có 48 công nhân không mang mũ bảo hộ. Hãy ước lượng tỷ lệ công nhân không mang mai bảo hộ trong thời gian làm việc với độ tin cậy 98%
Answer:
The percentage of workers not wearing the helmets is 5.3 %.
Step-by-step explanation:
A safety committee randomly examined 900 construction workers during their work, and found that 48 workers were not wearing helmets. Estimate the percentage of workers who do not wear protective masks during their working time with 98% confidence
total workers = 900
Not wearing helmet = 48
Percentage which are not wearing the helmets

What is the volume of this cylinder? 6m, 7m
Answer:
[tex]198\:\mathrm{m^3}[/tex]
Step-by-step explanation:
The volume of a cylinder is given by [tex]V=r^2\pi\cdot h[/tex], where [tex]r[/tex] is the radius of the cylinder and [tex]h[/tex] is the height.
What we're given:
[tex]r[/tex] of 3[tex]h[/tex] of 7Substituting given values, we get:
[tex]V=3^2\pi\cdot 7,\\V=9\cdot 3.14\cdot 7,\\V\approx 197.82\:\mathrm{m^3}=\boxed{198\:\mathrm{m^3}}[/tex], rounded the nearest cubic meter as requested in question.
Answer:
Volume of cylinder is 197.82 m ³.
Step-by-step explanation:
Here,
We have given thatDiameter of cylinder = 6 m
So, Radius of cylinder, r = 6 / 2 = 3m
Height of cylinder , h = 7 m
Value of π = 3.14
To find :-Volume of cylinder
Solution :-We know that,
Volume of cylinder = π × r ² × h
Substitute the values
Volume of cylinder = 3.14 × ( 3m ) ² × 7 m
volume of cylinder = 3.14 × 9m² × 7 m
Multiply , we get
Volume of cylinder = 197.82 m ³
Therefore, The volume of cylinder id 197.82 m ³.

A bank account has an initial deposit of $14,000. After 8 years, the bank account
has $18,000. Assuming that compounding interest is done annually and that no
withdrawals are taken, find the annual interest rate on the investment. If the interest is compounded annually what is the approximate interest rate on the investment?
Answer:
2.3%
Step-by-step explanation:
18000 = 15000( 1 + i)^8
Divide both sides by 15000
1.2 = (1 + i)^8
Take both sides to the 1/8 power
1.2^(1/8) = 1 + i
1.023051875220463 = 1 + i
Subtract 1 from both sides
i = 0.023051875220463
~ 2.3%
