Answer:
B
Step-by-step explanation:
because it is still a negative because a negative divided by a positive is still negative.
But 2 negatives turn positive so it is B

may I please have help ! Thank you so much .!
The equation is 15*w*14 = 2730
We simply multiply length, width and height to get the volume of the rectangular block.
That equation becomes 210w = 2730 because 15*14 = 210
From here, we divide both sides by 210
You should end up with w = 13
As a check, 15*w*14 = 15*13*14 = 2730 which confirms we have the correct replacement for w.
1. Find measure of angle GBC
A. 55°
B. 125°
C. 45°
D. 60°
(Show work)
Answer:
A. 55°
Step-by-step explanation:
So the line goes through two angles, 125° and 55°
Lets check, does the angle look larger than 90°
Remember, 90° mean the line is perpendicular, or goes straight up.
I see that it is not. The angle that is less than 90° (55°) is correct.
If my answer is incorrect, pls correct me!

Select the letter that correctly identifies the base of the prism.
The letter that correctly identifies the base of the prism is "a".
The prism shown in the above diagram is a triangular prism.The two distinctive sides that give a prism its name are its bases.So, the base of the prism should be in the shape of a triangle.The faces "b", "c", and "d" are rectangular, so they can not be the base of the prism.The faces "a" and "e" are triangular, so they are both the bases of the prism.Checking the options, we conclude that face "a" is the base of the given prism.Thus, the letter that correctly identifies the base of the prism is "a".To learn more about prisms, visit :

Jasper drinks a total of 1,500 ML of water every day. How many days would it take Jasper to drink 9L of water?
Answer:
6 days
Step-by-step explanation:
1 L has 1,000 mL
therefore you can create a proportion:
1500 mL / 1 = 9000 mL / d
cross-multiply to get:
1500d = 9000
d = 90/15 or 6

(c) Which number, 10, 11, or 12, will solve the equation in Part (b)? Show your work.
(d) How many pounds of potting soil did Emmanuel buy last week?
Answer:
plz help me I beg you
Answer:
1.) Amount of potting soil purchased last week.
2) 2p + 4 = 28
3.) 12 lbs
Step-by-step explanation:
1.) The unknown information is what we intend to find out using the information given, which is the amount of potting soil Emmanuel bought last week.
2.)
Let amount of potting soil bought last week = p
Amount bought this week = 2p + 4
Since amount bought this week = 28
Hence, we have ;
28 = 2p + 4
28 - 4 = 2p
24 = 2p
p = 24 / 2
p = 12
If a six-sided die(1-6) and a ten-sided die(1-10) are rolled simultaneously, then what is the probability of rolling both with a number greater than four
Answer:
[tex]Pr = 0.20[/tex]
Step-by-step explanation:
Given
[tex]n_1 = 10[/tex] ---- 10 sided
[tex]n_2 = 6[/tex] --- 6 sided
Required
[tex]P(x_1,x_2 > 4)[/tex]
First, list out the sample space
[tex]S = \{(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)[/tex]
[tex](3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6) (4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)[/tex]

[tex]n(S) = 60[/tex] --- total outcomes
The event that the outcome of both is greater than 4 is:
[tex]x_1,x_2> 4 = \{(5, 5) (5, 6)(6, 5) (6, 6)(7, 5) (7, 6) (8, 5) (8, 6)(9, 5) (9, 6) (10, 5) (10, 6)\}[/tex]
[tex]n(x_1,x_2>4) = 12[/tex]
So, the probability is:
[tex]Pr = \frac{n(x_1,x_2>4)}{n(S)}[/tex]
[tex]Pr = \frac{12}{60}[/tex]
[tex]Pr = 0.20[/tex]

find the equation of the line below (1,-2) (2,-4) *20 brainliest points* *pls help*
Answer:
y= -2x
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( -4- -2)/(2-1)
= ( -4+2)/( 2-1)
-2/1
-2
Using y = mx+b where m is the slope and b is the y intercept
y = -2x+b
Substitute a point into the equation
-2 = -2(1)+b
-2 = -2+b
b=0
y= -2x

Answer:
4845
.020639% (or 1/4845)
Step-by-step explanation:
For the first one we have to use combinations (because the order doesn't matter)
The formula is as follows:
for ACB
[tex]\frac{A!}{(A-B)!*B!}\\\\\frac{20!}{(20-4)!*4!}=4845[/tex]
2.
for probabilty the odds of an outcome is just: number of times the requirement is satisfied/total number of possibliites
we know that there are 4845 possbile groups and only one in which we get all of our friends so it's just
1/4845= .020639%
Andrew is two years older than Beatrice, and Chris is three years younger than Beatrice. The product of Andrew's age and Chris' age is 66. How old is Beatrice?
Answer:
9
Step-by-step explanation:
A = B + 2
C = B - 3
A x C = 66
A = Andrew
C = Chris
B = Beatrice
Multiply A and c together
(B + 2) x (b - 3)
b^2 - 3b + 2b - 6
b^2 -b - 6 = 66
b^2 - b - 72 = 0
factors of -72b^2 that add up to - b are -9b + 8b
b^2 + 8b -9b - 72
b (b + 8) -9(b + 8)
b = 9 or - 8
b = 9

Answer:
10
Step-by-step explanation:
10 is the greatest common factor that you can divide into both 40 and 50.
Answer:
10
Step-by-step explanation:
Try and find the prime factorization of 40 and 50.
40=2*2*2*5
50=2*5*5
Multiply the prime factors that are common to both numbers.
2*5=10
In the diagram, AC is a diameter of the circle with center 0. If m ZACB = 50°, what is ZBAC?
OA 50°
OB. 40°
O C. 80°
OD. 100°
Answer:
40degrees
Step-by-step explanation:
Find the diagram attached
Since the triangle ina semi circle is a right angle, hence <B = 90degrees
Also frm the diagram
<A + <B + <C = 180
<A + 90 + 50 = 180
<A + 140 = 180
<A = 180 - 140
<A = 40degrees
Hence the measure if m<BAC is 40degrees
One of two complementary angles is 35° larger than the other. What is the measure of both angles?
Answer:
Since the two angles are complementary, they add up to 90...
If we call the first one x, then the other must be 90-x...
Since they are 35 different, we write
x = (90 - x) + 35
now solve, and get
x = 90 - x + 35
x = -x + 125
2x = 125
x = 62.5 deg
the other must be
90 - 62.5 = 27.5 deg
