Answer:
2 hours = 4 * 30 minutes
30 * 3 = 90
90 * 3 = 270
270 * 3 = 810
810 * 3 = 2430
So after 2 hours you will have 2430 bacteria cells.

Answer:
68
Step-by-step explanation:
the square shape on the corner means it is a right angle, which is 90 degrees
--> that means the value which comes out when you subtract 22 from 90 is the angle left, which is "a" in this case.
90-22=68
Work out the area of this semicircle with radius 3cm give your answer in terms of pie
Answer:
A=4.5π
The formula for finding a circle is A=πr² so just plug in the value for the radius. Don't forget to divide the entire thing by 2 when you finish, cos it's a semi circle (which is a half circle)
Step-by-step explanation:
Cos Milky Said it.
Answer:
Answer=4.5π

1.4x-10=5x+15
2.2x+2=2x+2
Answer:
x = -25
x = infinite solutions
Step-by-step explanation for 1:
4(-25) - 10 = 5(-25) + 15
-100 - 10 = -125 + 15
-110 = -110
Step-by-step explanation for 2:
Both equations are the exact same. So whatever number you put, the answer will be right
Answer:
[tex]1)4x - 10 = 5x + 15 \\ 4x - 5x = 15 + 10 \\ - x = 25 \\ x = - 25[/tex]
[tex]2)2x + 2 = 2x + 2 \\ 2x - 2x = 2 - 2 \\ 2x(1 - 1) = 0 \\ x = 0[/tex]

The mean marks of 100 students were calculated as 65. At the time of checking it was found the marks 40 and 50 was wrongly copied and weeded out Find the correct mean marks.
Answer:
[ Because those two numbers are removed you need to reduce the number of terms to 98. ]
☆Solution☆
N=100
Mean=65
(Wrong Numbers=40,50)
Now,
Mean=Sum/No. of items
or,65=Sum/100
▪Sum=65×100=6500
After removing the unnecessary numbers,
New Sum=6500-40-50=6410
New no.of terms(N)=100-2=98
Now,
New Mean=New Sum/New N
=6410/98
=65.41

Khaya is delivering groceries to his mother who stays 8km from the shop. How long will it take him to cover this distance if he drives at an average speed of 65km/h? Give your answer rounded to the nearest minute.
Answer:
7.38 minutes
Step-by-step explanation:
Given
Distance= 8km
speed = 65km/h
Time=?
From physics,
Speed= distance/ time
Then substitute the values to find time
65= 8/ time
Time= 8/65
=0.1231 hrs
To Convert to minutes
1hr= 60 mins
0.1231 hrs = X minutes
Cross multiply, we have
X minutes=( 0.1231 × 60)/1
= 7.38 minutes
Hence, it takes 7.38 minutes for him to cover this distance
Find all solutions to the equation.
cos^2x + 2 cos x + 1 = 0 (4 points)
Answer:
cos^2x + (1+1)cos x + 1 = 0
or,cos^2x + cos x + cos x + 1 = 0
or,cos x(cos x + 1) + 1 (cos x + 1) = 0
or, (cosx + 1) + (cosx + 1) = 0
either
cosx + 1 =0 or cosx +1 =0
The sum of remote interior angels equals what?
Answer:
Each of the remote angles shares one side with the angle adjacent to the exterior angle. The equation means that the sum of measures of the remote interior angles is equal to the measure of the exterior angle of the triangle.
A soccer field has a length of 100 yards and a width of 60 yards. Which equation can you use to find the area of the soccer field?

Marcia drew a plan for a rectangular piece of material that she will use for a blanket. Three of the vertices are (-2.6, -1.5), ( -2.6,3.3), and (2.7, 3.3). What are the coordinates of the fourth vertex?
Answer:
[tex](2.7,-1.5)[/tex]
Step-by-step explanation:
The points are [tex]A(-2.6,1.5), B(-2.6,3.3), C(2.7,3.3)[/tex]
The fourth vertex will can be found by the points [tex]A[/tex] and [tex]C[/tex].
The angles between the sides of a rectangle are [tex]90^{\circ}[/tex].
The [tex]x[/tex] coordinate will be the same as [tex]C[/tex] and the [tex]y[/tex] coordinate will be the same as [tex]A[/tex]. The fourth verex is [tex]D[/tex].
So, the fourth vertex of the rectangular piece will be [tex](2.7,-1.5)[/tex].

Write the equation of each line in slope intercept form
goes through ( 0,4) and (-2,8)
Will give brainiest!!
Answer:
y = -2 x + 4
Step-by-step explanation:
Pass (0,4): y intercept b = 4
slope: m = (8-4) / (-2-0) = - 2
y = mx + b
y = -2 x + 4

The graph of the quadratic function r is shown on
the grid. If v(x) = x^2 and w(x) = v(x) + n, what is
the value of n?
Answer:
not sure sorry I do not know but what standard is it?
Answer:
[tex] - 4[/tex]
Step-by-step explanation:
An average quadratic function or
[tex] {x}^{2} [/tex]
has a vertex of 0,0
This function has a vertex of 0,4
This mean a vertical shift of 4 units down was applied.
Going down is negative so n equal

find the value of 956$ deposited for 12 years in a account paying 6% anuale interest when it is...
1 compounded quarterly
2componded anualy
Answer:
1. $1953.572. $1923.66Step-by-step explanation:
Compounded interest amount formula:
A = P(1 + r/n)^(nt)Given:
P = $956r = 6% = 0.06t = 12 yearsn = 4 and n = 11. Compounded quarterly
A = 956(1 + 0.06/4)^(4*12) = 956(1.015)^48 = 1953.572. Compounded annually
A = 956(1 + 0.06)^12 = 1923.66Answer:
Answer:
1. $1953.57
2. $1923.66
Step-by-step explanation:
Compounded interest amount formula:
A = P(1 + r/n)^(nt)
Given:
P = $956
r= 6% = 0.06
. t = 12 years
n = 4 and n = 1
1. Compounded quarterly
A = 956(1 + 0.06/4)^(4*12) = 956(1.015)^48 = 1953.57
2. Compounded annually
· A = 956(1+ 0.06)^12 = 1923.66

When you divide a fraction by a whole number greater than 1, is the quotient larger or smaller than the fraction?
9514 1404 393
Answer:
smaller for positive fractions
larger for negative fractions
Step-by-step explanation:
Dividing anything by a positive whole number greater than 1 gives a quotient that is closer to zero than the original dividend.
For positive fractions, the quotient is smaller.
(1/2)/3 = 1/6 . . . . 1/6 < 1/2
For negative fractions, the quotient is larger.
(-1/2)/3 = -1/6 . . . . -1/6 > -1/2
Members of the Video Digital club produce short videos. At the end
of each school year, the club hosts a Video Digital festival at a local
theater to show the community its top 25 videos.
Part A:
The club has realized from experience that when they don't charge
for admission, 800 people come. For every dollar they charge for
admission, 8 fewer people come. Write an inequality that they can
use to determine the price, p, in dollars that the club must charge for
at least 750 to come to the video festival
Part B: solve the inequality you wrote to in part A
Part C: explain in words what the solution to the inequality means in terms of the situation. Explain why the direction of the inequality sign in the solution makes sense.
