what is the chancr of rolling a 7 or a 9 on two dice .
Answer:
5/18 0r 27.77%
Step-by-step explanation:
I am assuming both are six-sided and have numbers 1-6 on each of the six sides. There are 36 possible roll combinations. Of the 36, four result in 9 and six result in 7. Therefore there is a 10/36 chance of rolling a 7 or a 9. That can be simplified however by dividing by two on both numbers. That equals 5/18. As a percent you would divide 5 by 18 and get 0.2777. After that you multiply 0.2777 by 100 to get 27.77%.
Need help on this question asap pleasee :)
Answer:
Step-by-step explanation:
Formula for total surface area of of the triangular prism is:
Total Surface area (S) = Ph+ 2B
P = Perimeter of the triangular base
P = 6 + 8 + 10
P = 24 cm
h = height of the prism = 10 cm
B = area of the base
B = ½*bh = ½*8*6
B = 24 cm
S = 24*10 + 2(24)
S = 240 + 48
S = 288 cm²
Total surface area = 288 cm²

Guys, someone got it wrong. Were back at 56..Please give me the correct answer, guys.
Answer:
8 + 6 = 14
14 x 4 = 56
56 x 1/2(basically just dividing by 2) = 28 mm2
Formula of area of a trapezoid:
B1(base 1) + B2(base 2) x H(height) x 1/2(basically just dividing by 2)
In this case, 8 is your base your other base is 6 and your height is 4.

{(0, 1), (−4, 1), (4, 2), (−4,−1)}
{(3, 2), (2,1), (−1, 2), (3,3)}
{(1, 2), (2,4), (−1, 2), (0,3)}
Hi there!
»»————- ★ ————-««
I believe your answer is:
D) {(1, 2), (2,4), (−1, 2), (0,3)}
»»————- ★ ————-««
Here’s why:
A function is a relation in which one element of the domain is assigned to exactly one element of the range. This means that the domain (x) values must not repeat.⸻⸻⸻⸻
Option A's answer is incorrect, as the domain value of '5' repeats.
{(5, 0), (0, 1), (5, 2), (4,4)}
⸻⸻⸻⸻
Option B is not a function due to the repeating '-4' value.
{(0, 1), (−4, 1), (4, 2), (−4,−1)}
⸻⸻⸻⸻
The '3' in option C's given relation repeats.
{(3, 2), (2,1), (−1, 2), (3,3)}
⸻⸻⸻⸻
Option D is the correct answer, as there are no domain values that repeat.
{(1, 2), (2,4), (−1, 2), (0,3)}
Therefore, option D is a function.
⸻⸻⸻⸻

Part A: If (62)x = 1, what is the value of x? Explain your answer. (5 points)
Part B: If (60)x = 1, what are the possible values of x? Explain your answer. (5 points)
pls explain
Answer:
Part A : 1/62 Part b : 1/60
Step-by-step explanation:
Well lets start with part A
(62)x=1
anything in parenthesis means multiply
62x= 1
divide everything by 62 to get x by itself
x= 1/62
Part A : 1/62
Part B : 60x = 1
x = 1/60

Determine the length of the radius of the circumscribed circle to the right triangle with the legs 7 cm and 4cm.Round your answer to the nearest hundredth
Answer:
4.03cm
Step-by-step explanation:
Note that the diameter of the circumscribed circle to the right triangle is the hypotenuse of the triangle.
To get the diameter, we will use the pythagoras theorem as shown;
d² = 7² + 4²
d² = 49 + 16
d² = 65
d = √65
d = 8.0622577
Since radius = d/2
radius = 8.0622577/2
radius = 4.0311288
Hence the radius of the circumscribed circle to the nearest hundredth is 4.03cm
Emeka is thrice as old as Dora and Dora is
7 years older than Dupe. If the sum of their
ages is 38, how old is Dupe?
A 2 years
years B 7 years

C 9 years
Answer:
Step-by-step explanation:
let duke be x years
dora be 7+x years
and emeka be 3(7+x) years
according to question ur equation is
3(7+x)+7+x+x=38
21+3x+7+2x=38
28+5x=38
5x=38-28
x=10/5
x=2
Answer:
Step-by-step explanation:
3(7+x)+7+x+x=38
21+3x+7+2x=38
28+5x=38
5x=38-28=10

Answer:
7w^3/5v
Step-by-step explanation:
42v^3w^4/30v^4w
42 = 6 * 7
30 = 6*5 , factor
6*7v^3w^4/6*5v^4w
6 is common, cancel
7v^3w^4/5v^4w
simplify w^4/w = w^3
v^3/v^4 = 1/v
therefore, 7w^3/5v is the answer

3(2^2x+3)-5(2^x+2)-156=0
Answer: [tex]x=3.0206[/tex]
Step-by-step explanation:
Given
[tex]3(2^{2x}+3)-5(2^x+2)-156=0[/tex]
Replace [tex]2^x[/tex] by [tex]y[/tex]
We can write
[tex]\Rightarrow 3(y^2+3)-5(y+2)-156=0\\\Rightarrow 3y^2+9-5y-10-156=0\\\Rightarrow 3y^2-5y-157=0\\\\\Rightarrow y=\dfrac{5\pm \sqrt{25-4(3)(-157)}}{2\times 3}\\\\\Rightarrow y=\dfrac{5+43.69}{6}\\\\\Rightarrow y=8.115\\\Rightarrow 2^x=8.115\\\therefore \quad x=3.0206[/tex]
Which of the following is the converse of the statement "If it is snowing,then
it is my birthday"?

to get the converse, interchange the hypothesis and conclusion
in this case the hypothesis is "if it is snowing" and the conclusion is "then it is my birthday"
Converse would then be "If it is my birthday, then it is snowing"
a designer created a scale drawing of a new kitchen. In the scale drawing, the length of the kitchen will be 8 feet. What scale did the designer use to create the scale drawing of the kitchen
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Scale\ length = 8ft[/tex]
Required
Determine the scale of the drawing
The question is incomplete, as the actual width of the kitchen is not given. The general explanation, however, is as follows:
The scale of a drawing is represented as:
[tex]Scale = Scale\ Measurement : Actual\ Measurement[/tex]
This gives:
[tex]Scale = 8ft : Actual[/tex]
Assume the actual length of the kitchen is 24ft.
The equation becomes:
[tex]Scale = 8ft : 24ft[/tex]
Divide by 8ft
[tex]Scale = 8ft/8ft : 24ft/8ft[/tex]
[tex]Scale = 1 : 3[/tex]
