Answer:
b = 77
Step-by-step explanation:
a² + b² = c²
36² + b² = 85²
1296 + b² = 7225
b² = 7225 - 1296
b² = 5929
[tex]\sqrt{b^2} =\sqrt{5929}[/tex]
b = 77

What is 2/5 divided by 4
the answer to the question is 0.1
Answer:
1/10 or 0.1
Step-by-step explanation:
You first rewrite the problem as 2/5÷4/1. Then you flip the second fraction for multiplication: 2/5*1/4. Now you multiply both numerators and denominators to get a final total of 2/20 which equals 1/10 or 0.1.
10.
Use the tangent ratio to find the size of the angle marked x, correct to the nearest degree.

Step-by-step explanation:
The Garys have a triangular pennant of area 420 in(squared)flying from the flagpole in their yard. The height of the triangle is 10 in less than 5 times the
base of the triangle. What are the dimensions of the pennant?
Answer:
The answer is given below:
Step-by-step explanation:
The computation of the dimension of the pennant is shown below:
As we know that
Area of the triangle = 1 ÷ 2 × base × height
where
x represents the base of the traingle
h represent the height that should be (5x - 10)
Now according to the above formula
420 = 1 ÷ 2 × x × (5x - 10)
840 = x(5x - 10)
840 = 5x^2 - 10x
5x^2 - 10x - 840 = 0
5(x^2 - 2x - 168) = 0
x^2 - 2x - 168 = 0
x^ - 14x + 12x - 168
x (x - 14) + 12(x - 14)
(x + 12) (x - 14)
So, here x = 14
Now height would be
= 5(14) - 10
= 60 inches
The first term of a sequence is 4 and the common
ratio is -2. What is the formula for the sequence
based on term number
Qy --2-(4)-1
ay -4.(-2)2-1
an = (4.-2)^2=1
an - 4.(-2)
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Geometric Progression.
So, we know that,
GP = a.r^(n-1)
here, a = 4 and r = -2
so we get as,
an = 4.(-2)^n-1
Option B.) is correct

Find the circumference of a circle with radius, r = 16.5m.
Give your answer in terms of pi.
Answer:
33π is the answer in terms of pi.
Step-by-step explanation:
Circumference of circle formula is C=πd.
Plug in the given values. We put 33 into d, because d represents diameter, and diameter is twice the radius(16.5), so we multiply 16.5 by 2. So far we have C=(π)(33).
C=(π)(33)=33π
Which choice represents the expression below as a single exponential
expression?
7.16.7.17
A. 7.142
B. 7.113.7.113
C. 7.113
D. 711
Answer:
C) (7.1)^13
Step-by-step explanation:
When you multiply numbers with the same bases but different exponents, the base stays the same, but the exponents get added:
a^x*a^y=a^(x+y)
(7.1)^6*(7.1)^7=(7.1)^(6+7)=(7.1)^13
Therefore, the correct answer is C) (7.1)^13
Answer:
C
Step-by-step explanation:
When multiplying numbers with exponents, you always add the exponents.
7.1^6+7
7.1^13
Hence, C

Question 5 :)) What is the measure of the missing angle?
a) Work out the value of angle x.
X
X=
b) Give reasons for your answer.
Answer:
x = 60° (Alternate angles)
Step-by-step explanation:
a) x = 60°
b) Reason: Alternate angles
Answer:x=60
Step-by-step explanation: all angles in a triangle add up to 180 degrees, x is the same as the angle next to it, therefore x=60 degrees

Answer:
D
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square.
Given
f(x) = - 0.6x² + 4.2x + 240 ← factor out - 0.6 from the first 2 terms
= - 0.6(x² - 7x) + 240
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² - 7x
f(x) = - 0.6(x² + 2(- 3.5)x + 12.25 - 12.25 ) + 240
= - 0.6 (x - 3.5)² + 7.35 + 240
= - 0.6(x - 3.5)² + 247.35
with vertex = (3.5, 247.35 )
The maximum value is the y- coordinate of the vertex
Then
f(x) = - 0.6(x - 3.5)² + 247.35 has a maximum value of 247.35

Answer:
Step-by-step explanation:
"SAS" is when we know two sides and the angle between them. use The Law of Cosines to calculate the unknown side, then use The Law of Sines to find the smaller of the other two angles, and then use the three angles add to 180° to find the last angle.
A faraway planet is populated by creatures called Jolos. All Jolos are either green or purple and either one-headed or two-headed. Balan, who lives on this planet, does a survey and finds that her colony of 852 contains 170 green, one-headed Jolos; 284 purple, two-headed Jolos; and 430 one-headed Jolos. One-headed Two-headed Total Green 170 Purple 284 Total 430 852 How many green Jolos are there in Balan's colony? O A. 138 B. 308 O C. 422 D. 260
Answer:
B. 308Step-by-step explanation:
Table is given belowFind the missing values.The one we are looking for is total of green = y.| 1 -H | 2-H | Total
Green | 170 | x | y
Purple | z | 284 | w
Total | 430 | v | 852
z = 430 - 170 = 260w = 260 + 284 = 544y = 852 - 544 = 308v = 852 - 430 = 422Correct choice is B
