Isabelle wants to become an astronaut! She has decided that she will
spend 20% of her day studying. If she is awake for 15 hours each day, how
long is she spending studying?
Answer:
3 hours
Step-by-step explanation:
Assuming that when the problem says "day" it refers to the hours of wakeness. The problem is essentially asking to find 20% of 15.
First, convert 20% to decimal form. To do this, divide (20) by 100, this is because a percent is out of 100.
20 / 100 = 0.2
Now multiply the hours of wakeness by the percent as a decimal;
15 * 0.2 = 3
Isabelle spends 3 hours studying.

Step-by-step explanation:if you like it press thank you ❤❤❤
2x-3y=2 4x+7y= -9
2x=2+3y
2x=2+3y
2 2
x=2+3y 4(2+3y) + 7y= -9
2 2
8+12y + 7y= -9

8+12y+14y = -9
2
8+12y+14y= -18
26y= -26
26y = -26
26 26
y= -1
4x+7(-1)= -9
4x+(-7)= -9
4x-7= -9
4x = -2 now lets check,4(-1) + 7(-1)= -9 or 2(-1)-3(-1)=2
4 4 2 2
x=-1 -4 +(-7) = -9 -1-(-3)=2
2 2 -1+3=2
-2-7= -9 2=2
-9= -9
so the answer is x= -1 and y= -1

Answer:
13
Step-by-step explanation:
we know both triangles are congruent, so we can make an equation
3x+7=10x-7
take 3x from both sides
7=7x-7
14=7x
x=2
20-7=CAD
m<CAD is 13
The value of the angle CAD in the figure given is 13°.
So, the correct option is 1.
Given is a figure, we need to find the measure of the angle CAD,
To find the required measurement we will show the triangles ABD and ACD are congruent,
So, considering the Δ ABD and Δ ACD,
BD ≅ DC [marked in the figure]
∠B ≅ ∠C [all the right angles are ≅]
DA = DA [common in the both Δs]
Hence, Δ ABD ≅ Δ ACD by SSA rule.
We get, ∠CAD ≅ BAD by CPCTC.
Therefore,
3x + 7 = 10x - 7
Combining the like terms,
10x - 3x = 7 + 7
7x = 14
x = 2
Put x = 2 in ∠CAD = 3x + 7,
∠CAD = 3(2) + 7
∠CAD = 6 + 7
∠CAD = 13°
Hence, ∠CAD = 13°.

Write an
equation that represents the line.
Use exact numbers.
Given:
The graph of a line.
To find:
The equation of the line.
Solution:
From the given graph it is clear that the line passes through the points (0,2) and (3,-2). So, the equation of the line is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-2=\dfrac{-2-2}{3-0}(x-0)[/tex]
[tex]y-2=\dfrac{-4}{3}x[/tex]
Adding 2 on both sides, we get
[tex]y=-\dfrac{4}{3}x+2[/tex]
Therefore, the equation for the given line is [tex]y=-\dfrac{4}{3}x+2[/tex].

y = x - 16
5y = 2x - 56
Step 2: Solve for x
Substitute in y: 5(x - 16) = 2x - 56Distribute 5: 5x - 80 = 2x - 56[Subtraction Property of Equality] Subtract 2x on both sides: 3x - 80 = -56[Addition Property of Equality] Add 80 on both sides: 3x = 24[Division Property of Equality] Divide 3 on both sides: x = 8Step 3: Solve for y

Answer:
Step-by-step explanation:
Area of a trapezoid is found with the formula, A=(a+b)/2 x h. Learn how to use the formula to find area of trapezoids.
The two parallel sides are the bases, and height, as always, is the perpendicular distance from one base to the opposite. The area of this parallelogram is its height (half-height of the trapezoid) times its base (sum of the bases of the trapezoid), so its area is half-height × (base1 + base2).
What is the next term of the geometric sequence?
81/25, 27/5, 9,
Each next term is the previous term multiplied with 5/3 so the next term in the sequence is 9*5/3=15
The next term of the geometric sequence 81/25, 27/5, 9, is 15.
The next term is the 4th term. Therefore, using geometric progression formula the 4th term can be found.
aₙ = arⁿ⁻¹where
r = common ratio
n = number of term
Therefore,
r = 27/5 ÷ 81/25 = 27/5 × 25/81 = 5 / 3
a = 81/25
a₄ = 81/25 × 5/3⁴⁻¹
a₄ = 81/25 × 5/3³
a₄ = 81/25 × 125/27
a₄ = 15
The next term is 15.

Solve, by completing the square, x^2=22x-5, leave your answer in surd form
Answer:
a) The complete square form = ( x-11)² = 116
b) x = 11 + 2√29
Step-by-step explanation:
Step(i):-
Given equation x² = 22x -5
⇒ x² - 22x + 5 =0
⇒ x² - 2× 11 x + (11)² -(11)² + 5=0
⇒ ( x- 11)² -121 +5 =0
⇒ ( x-11)² = 116
The complete square form = ( x-11)² = 116
Step(ii):-
⇒ (x-11) = √116 = √29 ×√4
⇒ x-11 = 2√29
⇒ x = 11 + 2√29
