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
HELP HELP HELP!!!!!!!
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

Classify the triangle as acute, obtuse, or right. Use the sides, 6,12,18, and decide wha
type of triangle it is.
Answer:
Acute because all angles are less than 90
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

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

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.

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

Step-by-step explanation:
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
Hope it helps!
