A father left 280 acres of land to be divided among his sons Al and Bob in the ratio 4:3, respectively. How many acres should Al receive?
Answer:
160 acres
Step-by-step explanation:
Given data
Total Amount of land= 280 Acres
Ratio=4:3
Total part = 4+3= 7
Applying the part to all method
let AI receive x acres
Then
4/7= x/280
cross multiply
7x= 280*4
7x=1120
x= 1120/7
x= 160
Hence AI will receive 160 acres

Answer:
x+35/5=2

x=-25
Answer:
[tex]\frac{1}{5} x[/tex]+7=2, x=-25
[tex]\frac{m}{7} -7=3[/tex], m= 105
[tex]\frac{3}{5} x+7=-20, x= -45[/tex]
[tex]-\frac{2}{7} t+5=17, t=-42[/tex]
4.9x+4.2=9.1, x=1
Explanation for last two:
[tex]-\frac{2}{7}t+5=17[/tex]
Step 1: Subtract 5 from both sides.
[tex]\frac{-2}{7} t+5-5=17-5[/tex]
[tex]\frac{-2}{7} t=12[/tex]
Step 2: Multiply both sides by 7/(-2).
[tex](\frac{7}{-2} )*( \frac{-2}{7}t )= (\frac{7}{-2} )*(12)[/tex]
t=−42
4.9x+4.2=9.1
Step 1: Subtract 4.2 from both sides.
4.9x+4.2−4.2=9.1−4.2
4.9x=4.9
Step 2: Divide both sides by 4.9.
[tex]\frac{4.9x}{4.9} \frac{4.9}{4.9}[/tex]

A Chevy Volt costs $29,600 in the United States. What would it cost in Canada?
Answer:

Step-by-step explanation:
The Chevy Volt costs in Canada is 37,888 Canadian Dollar
What is unitary method?Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit
What is the current marked value of US dollar to Canadian dollar?1 United States Dollar = 1.28 Canadian Dollar
According to the question
Chevy Volt costs in the United States = $29,600
As, per current marked value
1 United States Dollar = 1.28 Canadian Dollar
Cost in Canada = 29,600 * 1.28 Canadian Dollar
= 37,888 Canadian Dollar
Hence, the Chevy Volt costs in Canada is 37,888 Canadian Dollar

Keisha is playing a game using a wheel divided into eight equal sectors, as shown in the diagram. Each time the spinner lands on white, she will win a prize. If she spins this wheel twice, what is the probability she will win a prize on both spins? Please show all steps!
Answer:
[tex] \frac{4}{64} [/tex]
Step-by-step explanation:
The spinner is independent (the total won't be effected)
we know there is 2 whites with 8 coloured option.
[tex] \frac{2}{8} [/tex]
we want the probability of getting two whites.
[tex] \frac{2}{8} \times \frac{2}{8} = \frac{4}{64} [/tex]
there is 3 ways to work out probability, fraction, decimal and percentage (i'd personally say fraction is the most easiest)
The probability of Keisha to win a prize on both spins in a game of wheel which is divided in eight equal sectors is 1/16.
What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
Keisha is playing a game using a wheel divided into eight equal sectors, as shown in the diagram.
Each time the spinner lands on white, she will win a prize. If she spins this wheel twice,
Here, the white is appeared twice in the wheel and the total number of sector in wheel are 8. Thus the probability of first time to come white in the spin is,
[tex]P=\dfrac{2}{8}\\P=\dfrac{1}{4}[/tex]
The conditions are same for the second case. For this case, both result of both the spins of wheel are independent of each other.
Thus, by the chain rule, the probability both spin as white sector appear is,
[tex]P=\dfrac{1}{4}\times\dfrac{1}{4}\\P=\dfrac{1}{16}[/tex]
Thus, the probability of Keisha to win a prize on both spins in a game of wheel which is divided in eight equal sectors is 1/16.

y = 3.5
Step-by-step explanation:
The parallelogram given has opposite sides that are equal in length. Therefore, the diagonals bisect each other into two equal parts respectively.
Thus:

Divide both sides by 2
y = 7/2
y = 3.5

[tex]\Huge\boxed{x=11.8}[/tex]
Step-by-step explanation:
Hello There
cos = adjacent divided by hypotenuse
the adjacent side of the angle that has a measure of 49 is x and the hypotenuse is 18
so
[tex]cos49=\frac{x}{18}[/tex]
once again we want to isolate the variable using inverse operations
to get rid of the 18 we multiply each side by 18
[tex]\frac{x}{18} *=x\\cos49*18=18cos49[/tex]
we're left with
[tex]x=18cos49[/tex]
now we let the calculator do the rest of the work
we end up with
[tex]x=11.80906252[/tex]
our final step would be to round to the nearest tenth
so we can conclude that the x = 11.8

Find the measure of angle x?
Answer:
x = 43 degrees
Step-by-step explanation:
First, you have to see that there is a right angle of 90 degrees. Since that is there, you know that there is 90 degrees in the bottom and right side as well. So all you do in this question is do 90 - 47 to get your answer of 43 degrees.
