Answer:
It is 1/8
Step-by-step explanation:
If you split 1/4 into another half you will get 1/8
This is true because if you add 1/8 and 1/8 you get 2/8 which simplified is 1/4
What would Hope be attempting to find if she writes d(4) = 78(4)?
Answer:
d=78
Step-by-step explanation:
so you would divide both sides of the equation by 2×2
d×4÷(2×2)=78×4÷(2×2) <- you would do this to get rid of 4 so you cna get the d alone
d=78×4÷(2×2) <- thats the other side of the equation btw
then it would be:
d=39×2
d=78

What is AC for brainliest
•Triangle 1
#Find CD first use tan formula
tan(∅) = opposite / adjuscent
tan(45) = CD / 5
CD = 5 × tan(45)
CD = 5
•Triangle 2
#Now you can find AC use Pythagoras theorem (c = AC)
a² + b² = c²
4² + 5² = c²
16 + 25 = c²
41 = c²
c = √41
c = 6.4
so, AC is 6.4

Answer:
x = 10
Step-by-step explanation:
In the parallelogram below find the value of each variable. Hint: find the value of t first
Answer:
because this is a parallelogram
=> 3t - 15 = 2t + 10
⇔ t = 10 + 15
⇔ t = 25
with t = 25 => 3t - 15 = 3.25 - 15 = 60
we also have:
4r + (3t - 15) = 180°
⇔ 4r + 60° = 180°
⇒ 4r = 120°
⇔ r = 30
we also have;
4r = 3s
=> 4.30 = 3s
⇔ s = 4.10
⇔ s = 40
Step-by-step explanation:
You can use the fact that sum of all angles of a parallelogram is 360 degrees and the sum of two adjacent angles in a parallelogram is 180 degrees.
The value of the variables used in the figure are:
r = 30
s = 40
t = 25
What are some useful properties of angles of a parallelogram?Sum of all angles of a parallelogram is 360 degrees.Sum of two adjacent angles in a parallelogram is 180 degrees.Using the above facts to find the values of specified variables[tex]4r + (3t - 15) + (2t + 10) + 3s = 360^\circ\\4r + 3s + 5t = 365[/tex]
And
[tex]3t - 15 + 4r = 180 \cdots (1)\\3t - 15 + 3s = 180\cdots (2)\\3s + 2t + 10 = 180\cdots (3)\\4r + 2t + 10 = 180\cdots (4)[/tex]
We get 2 systems of linear equations.
First system consists of equation 1 and equation 4
Second system consists of equation 2 and equation 3
From equation 1 and 4, as both's left side is equal to 180, thus they are equal too, or
[tex]3t - 15 + 4r = 4r + 2t + 10\\3t - 2t = 4r - 4r + 10 + 15\\t = 25[/tex]
Putting it in equation 1, we get:
[tex]3t - 15 + 4r = 180\\3 \times 25 + 4r = 180 + 15\\75 + 4r = 195\\\\r = \dfrac{195 - 75}{4} = 30[/tex]
Putting the value t = 25 in second equation, we get:
[tex]3t - 15 + 3s + 180\\3 \times 25 - 15 + 3s = 180\\60 + 3s = 180\\\\s = \dfrac{180 - 60}{3} = 40[/tex]
Thus, the values of the specified variables in the given graph are:
r = 30
s = 40
t = 25

3. A gardener mows 5 out of every 6 days. How many days would he mow
in a 90-day period of time? Plz I really need help ASAP
Answer:
Step-by-step explanation:
90(5/6)
450/6
75
9514 1404 393
Answer:
75
Step-by-step explanation:
90 = 6 × 15
There are 15 6-day periods in 90 days. The gardener will have mowed ...
15 × 5 = 75
times in those 15 periods.
He will mow 75 times in a 90-day period.
__
If you like, you can set up a proportion for the unknown number of mowings (m).
mows/days = m/90 = 5/6
Multiply by 90 to solve for m.
m = 90(5/6) = (90/6)(5) = 15(5) = 75 . . . . . . this should look like the above
2(x + 4) − 1 = 2x + 7
Answer:
All real numbers are solutions to this problem.
Step-by-step explanation:
I) Simplify:
2(x + 4) - 1 = 2x + 7
x + 4 - 0.5 = x + 3.5 (Divide by 2)
x + 3.5 = x + 3.5 (Simplify x + 4 - 0.5)
x = x
II) Conclusion:
Any real number will work as a solution.

3 A Gas station A charges $3.50 per gallon of gas plus 58 for a car wash. Gas station B charges $3.25 per gallon of gas plus S10 for a car wash. How many gallons of gas must a customer purchase for the total cost to be the same at both gas stations?
9514 1404 393
Answer:
8 gallons
Step-by-step explanation:
The $2 difference in the price of a car wash is made up by the gas purchase at the rate of $0.25 per gallon. So, it takes ...
$2/($0.25/gal) = 8 gal
to make the costs the same.
The customer must purchase 8 gallons for the total cost to be the same at both gas stations.
___
3.50g +8 = 3.25g +10 . . . . costs at each station for g gallons of gas + wash
0.25g = 2 . . . . . . . . . subtract 3.25g+8 from both sides
g = 2/.25 = 8 . . . . . . the way we did it above

Answer:
The roots of the quadratic equation are , .
Step-by-step explanation:
The roots of the quadratic equation are , .
Step-by-step explanation:
As given the equation in the form
Simplify the above equation
(x-2)-x = 3x × (x-2)
x-2 - x = 3x² - 6x
3x² - 6x + 2 = 0
