Select all the equations that are equivalent to the given equation. 1/5 (t + 2) = 5/6
1/5 t + 2/5 = 5/6
1/5 t = 7/10
1/5 t + 7 = 5/6
t = 2 1/6
t = 3 1/2
plz this question is worth 50 ponits
Answer:
t = 2 1/6
1/5 t + 2/5 = 5/6
Step-by-step explanation:
1/5 (t + 2) = 5/6
Multiply each side by 5
t+2 = 5*5/6
t+2 = 25/6
Subtract 2 from each side
t+2 -2 = 25/6 -12/6 ( using the same denominator)
t = 13/6 = 2 1/6
We can also distribute
1/5 t + 2/5 = 5/6
Subtract 2/5 from each side
1/5t = 5/6 -2/5
Get a common denominator
1/5t =25/30 - 12/30
1/5t = 13/30
Multiply each side by 5
t = 13/30 *5
t = 13/6
ANSWER : t = 2 1/6
1/5 t + 2/5 = 5/6
Step-by-step explanation:
1/5 (t + 2) = 5/6
Multiply each side by 5
t+2 = 5*5/6
t+2 = 25/6
Subtract 2 from each side
t+2 -2 = 25/6 -12/6
t = 13/6 = 2 1/6
We can distribute
1/5 t + 2/5 = 5/6
Subtract 2/5 from each side
1/5t = 5/6 -2/5
Get common denominator
1/5t =25/30 - 12/30
1/5t = 13/30
Multiply each side by 5
t = 13/30 *5
t = 13/6

Find the approximate perimeter of the
isosceles triangle APAZ plotted below.
Round your final answer to the nearest
hundredth.
Answer:
20.03
Step-by-step explanation:
To find the perimeter of the triangle, we need to find the length of each side, and we can do this finding the distance from each pair of vertix of the triangle:
Knowing that P = (3, -4), A = (-4, 1) and Z = (-2, 3), we have:
side PZ: distance = sqrt((3 - (-2))^2 + (-4 - 3)^2) = 8.6023
side PA: distance = sqrt((3 - (-4))^2 + (-4 - 1)^2) = 8.6023
side AZ: distance = sqrt((-4 - (-2))^2 + (1 - 3)^2) = 2.8284
So the perimeter is PZ + PA + AZ = 8.6023 + 8.6023 + 2.8284 = 20.03
Consider a single spin of the spinner.
Which events are mutually exclusive? Choose all that apply.
a
landing on an unshaded sector and landing on a number less than 2
b
landing on a shaded sector and landing on a 3
c
landing on an unshaded portion and landing on an odd number
d
landing on a shaded sector and landing on an even number
e
landing on a shaded sector and landing on a number greater than 3
The question is incomplete
Find attached to the question, the appropriate diagram
Answer:
a) landing on an unshaded sector and landing on a number less than 2
b) landing on a shaded sector and landing on a 3
Step-by-step explanation:
Mutually exclusive events are two events that can occur separately on their own but they cannot occur together or at the same time.
The options given are explained below:
We have two shaded sectors: 1 and 4
We have two unshaded sectors : 2 and 3
a) landing on an unshaded sector and landing on a number less than 2
Looking at option a, we find out that it is possible for the spinners to land on an unshaded sector separately likewise on a number less than 2 but it cannot land on an unshaded sector AND and number less than 2 because looking at the spinner, the numbers on the unshaded sectors are 2 ( is equal to two) and 3 ( which is above 2).
Therefore this option is mutually exclusive and correct.
b) landing on a shaded sector and landing on a 3
It is possible to land on a shaded sector likewise it is possible to land on a 3 but it is not possible to land on a shaded sector and land on a 3 at the same time.
This is because, the number on the shaded sector is 1 and 4 and the number on the unshaded sector is 2 and 3, we have only one spinner so the spinner can only land on one sector at a time.
Therefore, Option b is a mutually exclusive event and it is a correct option.
c) landing on an unshaded portion and landing on an odd number
The unshaded portion on the spinner has number 2 and 3 on them, therefore it is possible to land on an unshaded portion and odd number which is 3 at the same time.
Option c is not a mutually inclusive event and it is wrong.
d) landing on a shaded sector and landing on an even number
The shaded sector on the spinner has number 1 and 4 on them, therefore it is possible to land on an shaded sector and even number which is 4 at the same time.
Option d is not a mutually inclusive event and it is wrong.
e)landing on a shaded sector and landing on a number greater than 3
The shaded sector on the spinner has number 1 and 4 on them, therefore it is possible to land on an shaded sector and a number greater than 3 which is 4 at the same time.
Option e is not a mutually inclusive event and it is wrong.
Therefore, option a and option b are mutually exclusive events and they are correct.
Answer:
a. landing on an unshaded sector and landing on a number less than 2
e landing on a shaded sector and landing on a number greater than 3
Step-by-step explanation:
Two events ; for example events A and B are said to be mutually exclusive , if they cannot both occur simultaneously.In set theoretical notation , we say that the two sets A and B are disjoint set.
i.e
A ∩ B = ∅
Pr (A ∩ B) = 0
The intersection of A and B is an empty set and as such there is no intersection.
From the given options; option a and e are correct because ;
a.
landing on an unshaded sector and landing on a number less than 2
Landing on an unshaded portion would 2 or 3.
Landing on a number less than 2 would be 1.
There is no intersection and as such these events are mutually exclusive.
e.
landing on a shaded sector and landing on a number greater than 3
Landing on a shaded portion would be 1 or 4.
Landing on a number greater than 3 would be just 4.
The intersection of both events will be an empty set (∅)
As such these events are not mutually exclusive.
3a + 2 - 5a = -14. Can someone solve this for me.
Answer:
a = 8
Step-by-step explanation:
-2a + 2 = -14
-2a = -16
-16/-2 = 8
a = 8
Answer:
a=8
Step-by-step explanation:
3a + 2 - 5a = -14
Combine like terms
-2a +2 = -14
Subtract 2 from each side
-2a +2-2 = -14-2
-2a = -16
Divide each side by -2
-2a/-2 = -16/-2
a = 8

A car wash charges two prices depending on the size of the vehicle. The table shows the number of cars and the number of SUVs washed in the past 3 hours. The total earnings for hours 1 and 2 are given. Each car costs the same price, and each SUV costs the same price. The system of equations can be used to represent the situation.
In the system of equations, x represents the, _____and y represents the_____.
If the system of equations is graphed in a coordinate plane, the coordinates (x, y) of the intersection of the two lines are______.
The total cost of 1 car and 1 SUV is $_____.
The total earnings for hour 3 are $______.
The missing part of the picture is:
4x + 2y = 84
3x + 5y = 126
Answer:
see below
Step-by-step explanation:
In the system of equations, x represents the, price to wash a car and y represents the price to wash an SUV.
If the system of equations is graphed in a coordinate plane, the coordinates (x, y) of the intersection of the two lines are the price of the car wash (x) and the price of the SUV wash (y)______.
x=12 and y = 18
x+y = 12+18 = 30
The total cost of 1 car and 1 SUV is $_30____.
5x+4y = 5(12)+4(18) = 60+ 72 =132
The total earnings for hour 3 are $_132_____.
Answer:
x: cost of 1 car wash
y: cost of each SUV wash
(12,18)
The total cost of 1 car and 1 SUV is $30
The total earnings for hour 3 are $132
Step-by-step explanation:
4x + 2y = 84
y = 42 - 2x
3x + 5y = 126
3x + 210 - 10x = 126
7x = 84
x = 12
y = 42 - 2(12) = 18
1 car and 1 SUV
12 + 18 = 30
For 3 hours:
5x + 4y
5(12) + 4(18)
132
Kathy found the volume of the figure using the expression (4 * 3 * 8) + (10 * 3 * 4). Sandy found the volume of the figure using the expression (3 * 10 x 4) + (4 * 3 * 4). Use the drop-down menus to explain who is correct. 10 cm Click the arrows to choose an answer from each menu, The expression for the volume of the figure was correctly determined by Choose... because the figure was divided into two rectangular → prisms that Choose...
Answer:
The correct options are;
1) Sandy is correct
2) The figure was divided into two rectangular prisms that are calculated separately
Step-by-step explanation:
Here we have to divide the figure into two rectangular prisms so as not to calculate for a dimension twice
Therefore, the figure can be split into a horizontal prism at the top with dimensions and volume = 10 × 4 × 3 and the vertical prism below will now have a dimension and hence, volume of 4 × 4 × 3
Therefore the volume of the figure is the sum of the volumes of the two prisms found as follows;
Volume of the figure = 10 × 4 × 3 + 4 × 4 × 3 = 168
We can try the othe way to confirm as follows
Volume of the prism below = 4 × 3 × 8 = 96
Volume of the horizontal prism above is now = 4 × 3 × 6 = 72
Volumre of the figure = 96 + 72 = 168
Therefore, since the volume = (10 × 4 × 3) + (4 × 4 × 3), Sandy is correct
Because the figure was divided into two rectangular prisms that are calculated separately.
Answer:
1(sandy is correct)
2(do not overlap
