Answer:
9.1 units
Step-by-step explanation:
formula of a distance of two points:
[tex]\sqrt{(x1-x2)^2+(y1-y2)^2}[/tex] where x and y indicate the coordinates of the points
[tex]\sqrt{(4+5)^2 + (-1)^2} = \sqrt{81 + 1} = \sqrt{82} = 9.1 units[/tex]

In a school of 500 students, a random sample of 60
students are asked what
their favorite subject is. The
results are in the table. Based on this sample, how
many students in the school would we predict have
math as a favorite subject?
Answer:
150
Step-by-step explanation:
'x' = number of students out of 500 who selected math
18/60 = x/500
cross-multiply:
60x = 9000
x = 150

PLEASE HELP! What is the ratio of the volumes of two spheres, if the ratio of their radii is 13: 9
Answer:
[tex] V_1 : V_2= 2197 : 729[/tex]
Step-by-step explanation:
Let the volumes of both the spheres be [tex] V_1, \:V_2[/tex] and their radii be [tex] r_1, \:r_2[/tex] respectively.
[tex] \huge r_1 : r_2= 13 : 9[/tex] (given)
[tex] \implies\huge \frac{r_1}{r_2}= \frac{13}{9}.....(1)[/tex]
[tex] \huge \frac{V_1}{V_2}=\frac{\cancel {\frac{4}{3} \pi} r_1^3}{\cancel {\frac{4}{3} \pi} r_2^3}[/tex]
[tex] \huge \frac{V_1}{V_2}=\frac{ r_1^3}{r_2^3}[/tex]
[tex]\huge \frac{V_1}{V_2}=\bigg(\frac{ r_1}{r_2}\bigg) ^3..... (2)[/tex]
From equations (1) & (2), we have:
[tex]\huge \frac{V_1}{V_2}=\bigg(\frac{13}{9}\bigg) ^3[/tex]
[tex] \huge \frac{V_1}{V_2}=\frac{2197}{729}[/tex]
[tex] \huge \therefore V_1 : V_2= 2197 : 729[/tex]
Thus, the ratio of the volumes of two spheres would be 2197 : 729.
Answer:
2197:729

Can i have some help please!!
Answer: $93649
Step-by-step explanation:
Since this is an exponential growth problem, then we can use the equation 50,000(1.04)^16. Solve it and you get 93649.06228. Round to the nearest dollar, which is probably whole number, so it is 93649.
What is the measure of the other acute angle ?
AD is tangent to circle B at point C. What is the measure of BCA? O 40° O 50° O 90° O 180°
Answer:
C
90
Step-by-step explanation:
B is likely the center, I think. You can't do it otherwise.
The tangent and a radius of a circle meet at 90o
therefore the answer is 90.
All of this could be confirmed with a diagram.

Factor by grouping:
3x^(3)-6x^(2)+15x-30
the answer would be b on scholar
Answer:
3 (x² + 5) (x - 2)
Step-by-step explanation:
3x³- 6x² + 15x - 30
=> 3 (x³ - 2x² + 5x - 10)
=> 3 [x²(x - 2) + 5 (x - 2)]
=> 3 (x² + 5) (x - 2)

The required equation of the circle that shown in the graph is,
(x + 1)² + (y - 2)² = 4 where (-1 , 2) is the center of the circle and 2 unit is the radius of the circle. Option C is correct.
A graph of the circle is shown, It is to determine the equation of the circle.
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the circle's center on the coordinate plane and r is the circle's radius.
From the graph, the center is ( -1, 2) and the radius is 2. Now put these values in the standard equation of the circle.
(x - (-1))² + (y - 2)² = 2²
(x +1 )² + (y - 2)² = 4
Thus, the required equation of the circle that shown in the graph is,
(x + 1)² + (y - 2)² = 4 where (-1 , 2) is center of the circle and 2 unit is the radius of the circle. Option C is correct.

The animal department wants to estimate the kangaroo population. So they marked 30 kangaroos with paint. These kangaroos were then released into the jungle. After four months 600 kangaroos were caught. Among these Kangaroo, 18 were marked. To the nearest whole number,what is the best estimate for the kangaroo population?
Answer:
1000
Step-by-step explanation:
From the above question
We have the following parameters
30 were intially Marked
600 were caught and out of it 18 was marked
The formula for the best estimate of the population is calculated as:
Total population = Initial marked kangaroo × Number of caught kangaroo/Number of kangaroo marked after they were caught
= 30 × 600/18
= 1000

Answer:
B. A = 1/2(7)h
Step-by-step explanation:
Formula for area of triangle = 1/2 x base x height
H is the height of the triangle.
7cm is identified as the base of the triangle.
1/2(7)h is also the same thing as 1/2 x 7 x h basically.
Answer:
B
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 7 and h = h , then
A = [tex]\frac{1}{2}[/tex] (7) h → B
Solve the equation for a.
3a+13.61=−9.43
Answer: a = -7.68
STEPS:
- Subtract 13.61 from both sides
- Simplify
- Divide both sides by 3

Which exponential equation is equivalent to the logarithmic equation below?
log 300 = a
A. 3000 = 10
B. a10 = 300
C. 100 = 300
D. 30010 = a
Answer:
[tex]\implies\boxed{ 10^a = 300 }[/tex]
Step-by-step explanation:
We are provided logarithmic equation , which is ,
[tex]\implies log_{10}^{300}= a [/tex]
Here we took the base as 10 , since nothing is mentioned about that in Question .Say if we have a expoteintial equation ,
[tex]\implies a^m = n [/tex]
In logarithmic form it is ,
[tex]\implies log_a^n = m [/tex]
Similarly our required answer will be ,
[tex]\implies\boxed{ 10^a = 300 }[/tex]
