Rico spins the spinner twice and determines the sums of the spins. Fill in the sample space to determine the possible outcomes. What is the probability that Rico will get a sum less than or equal to 8? A 13\frac{1}{3} 3 1 B 23\frac{2}{3} 3 2 C 89\frac{8}{9} 9 8 D 59\frac{5}{9} 9 5
Answer:
2/3
Step-by-step explanation:
Sample space for the sum of 2 spins :
Number on spinner = 2, 5, 4
____ 2 ___ 5 _____4
2___ 4 ___ 7 _____ 6
|
5___ 7 ___ 10 ____ 9
|
4___ 6 ___ 9 ____ 8
Hence,
(4, 7, 6, 7, 10, 9, 6, 9, 8)
Probability of getting a sum less than or equal to 8;
Probability = required outcome / Total possible outcomes
Required outcome =, sum ≤ 8 = 6
Total possible outcomes = 9
P(sum ≤ 8) = 6/9 = 2/3
The surface area of a cube can be found using the formula S = 6e. If a cube
has an edge of 3.5, what is the surface area of the cube?
Answer:
S = 73.5 unit³
Step-by-step explanation:
[tex]A_{s} = 6e^{2}[/tex]
[tex]A_{s} = 6 (3.5)^{2}[/tex]
[tex]A_{s} = 6 (12.25)[/tex]
[tex]A_{s} = 73.5[/tex]
Answer:
73.5 unit^2.
Step-by-step explanation:
Area = e^2
Area of one face = 3.5^2 = 12.25 unit^2.
So total surface area = 6 * 12.25
= 73.5 unit^2.
Sally's age is 2 plus 3 times John's age. Together, Sally and John's age equals 30. How old is Sally?
Answer:
Sally is 23 years old.
Step-by-step explanation:
John's age is completely unknown, so it is known as x
Meanwhile, Sally's age can be represented as 3x+2
The sum of both ages is 30.
So, x+3x+2=30
Combine like terms.
4x+2=30
Subtract 2 from both sides.
4x=28
Divide both sides by 4.
x=7
John is 7 years old.
Sally's age: 3(7)+2=23
Sally is 23 years old.

Sunita creates a scale model of an Aeroplan. The scale of the model is 5cm to 9cm. Sunita's model has a wingspan of 36cm. What is the wingspan of the rea Aeroplan.
Step-by-step explanation:
Given
Model to Actual = 5:9
5cm in Model = 9cm actual
1cm in model = (9/5)cm = 1.8cm
36cm in model = 1.8cm x 36 = 64.8cm

Find x and TU
Show all the work
Answer:
x = 10
TU = 24
Step-by-step explanation:
To find the value of x, we use the trapezoid mid-segment theorem
The sum of the lengths of the two parallel sides is equal to twice the length of the mid segment
Mathematically, we have this as;
2(2x+ 4) = 2x-4 + 3x + 2
4x + 8 = 5x - 2
5x -4x = 8 + 2
x = 10
TU = 2x + 4 ; = 2(10) + 4 = 20 + 4 = 24
here's a picture help lol
Two sides of a triangle have lengths 7 and 15. Which inequality represents the possible lengths for the third side , x?
Answer:
8 < x <22
Step-by-step explanation:
In this question we know the two sides of the triangle to be 7 and 15, let's all the other side x
One one side of the inequality we have:
7+15>x
22 > x
On the other side we have
7 + x > 15
X > 15-7
X>8
When we rearrange these inequalities above we have
8<X<22
We saw from the calculations that 8 is less than X and X is less than 22.

Debra and Alexandria can finish a plowing job in two hours if they work together. Debra can do the job in 7 hours by herself. How long would it take Alexandria to finish the same job alone?
Answer:
2 hours 48 minutes
Step-by-step explanation:
Debra=1 plowing job / 7 hours
Debra+Alexandra=1 plowing job / 2 hours
1/2-1/7
=7/14-2/14
=5/14
=1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
14/5 hour=2 hours 48 minutes (hope hits helps)
Alexandria to finish the same job alone in, 2 hours 48 minutes
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Debra and Alexandria can finish a plowing job in two hours if they work together.
And, Debra can do the job in 7 hours by herself.
Hence, We get;
For Debra = 1 plowing job / 7 hours
Debra + Alexandra = 1 plowing job / 2 hours
Hence, Time to take Alexandria to finish the same job alone is,
= 1/2 - 1/7
= 7/14 - 2/14
= 5/14
= 1/14/5 (Alexandra can do 1 unit of plowing job per 14/5 hours)
= 2 hours 48 minutes
Thus, Alexandria to finish the same job alone in, 2 hours 48 minutes

I have attached the complete question with the triangle.
Answer:
x = 6
Step-by-step explanation:
From the image attached we are told to find x in the triangle.
The triangle is a right angle triangle and so we can use pythagoras theorem to find x.
x² = 6.5² - 2.5²
x² = 42.25 - 6.25
x = √36
x = 6
