Answer:
3.71 = (3.7 × 10)(1 × 10) = 3710.
Step-by-step explanation:
This fraction is alread reduced, We can't reduce it any further). As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 3710 is also equal to 3710 when expressed as a mixed number.

In triangle ADE:
sum of all angles is 180.
3x-10+58+42=180
3x+90=180
3x=180-90
3x=90
x=90/3
x=30
As line DA and CB are parallel:
angle D=angle C
angle y=58
In angle BCE, sum of angles is 180.
z+58+42=180
z+100=180
z=180-100
z=80

Midpoints & endpoints
Answer:
The coordinates of A are (1, -4)
Step-by-step explanation:
The formula for finding a midpoint is ((x1 + x2) / 2, (y1 + y2) / 2)
However, in this problem, we're already given the midpoint. We're trying to find an endpoint. So, the equation changes into:
((x + 9) / 2 = 4, (y + 0) / 2 = -2)
For the x and y coordinates, multiply both sides by 2
(x + 9 = 8, y = -4)
(x = -1, y = -4)
Rewrite as coordinates.
(-1, -4)

for another 1 hours 10 minutes.
What is her total travel time in hours and minutes
Answer:
4hr and 30 min
Step-by-step explanation:
2hr and 50 min + 30 min = 3hr and 20 min
3hr and 20 min + 1hr and 10min = 4 hr and 30min

Hi,
Answer is $0.19
Step-by-step explanation:-
We know that:-
15 dimes = $1.50
20 nickels = $1.00
8 quarters = $2.00
half dollar = $0.50
19 pennies = $0.19
Total = $5.19
Since Billy spended $5, so,
$5.19 - $5 = $0.19
Hope it helps you...
Some math help please?
Answer:
∠ LMP = 77° , ∠ NMP = 103°
Step-by-step explanation:
The 2 angles on the straight line sum to 180° , that is
∠ LMP + ∠ NMP = 180 , substitute values
- 16x + 13 - 20x + 23 = 180 , that is
- 36x + 36 = 180 ( subtract 36 from both sides )
- 36x = 144 ( divide both sides by - 36 )
x = - 4
Then
∠ LMP = - 16x + 13 = - 16(- 4) + 13 = 64 + 13 = 77°
∠ NMP = - 20x + 23 = - 20(- 4) + 23 = 80 + 23 = 103°
A washer and a dryer cost 860 combined. The washer costs 90 less than the dryer. What is the cost of the dryer?
Answer:

Step-by-step explanation:
860 ÷ 2 = 430
430 - 90 = 340
Write a rule for the geometric sequence with the given description. The first term is -3, and 5 is the previous term.
Answer:
The rule is (-3)(5)^(n-1).
Step-by-step explanation:
OK so the common ratio is 5 and first term = -3.
nth term = ar^(n-1)
= (-3)(5)^(n-1).
14 +3n = 8n - 3(n - 4)
Answer:
n=1
Step-by-step explanation:
Start by distributing the -3 to (n-4)
14+3n=8n-3n+12
Then combine like terms on the right
14+3n=5n+12
Subtract 12 from both sides
2+3n=5n
Subtract 3n from both sides
2=2n
Divide both sides by 2
1=n
Solve for x: the quantity of x plus 20 over 2 = 3x
Question 6 options:
x = 10
x = 4
x = −14
x = −17
Answer:
B. x = 4
Step-by-step explanation:
Answer: X = 4
Step-by-step explanation:
(x + 20)/2 = 3x
x + 20 = 2*3x
x + 20 = 6x
20 = 6x - x
20 = 5x
20/5 = x
x = 4

Which pair of transformations moves quadrilateral 1 to quadrilateral 2?
a:Reflect over the line y = -3, then rotate it 90 degrees counterclockwise about the origin
b:Reflect it over the x-axis, then rotate it 180 degrees about the origin
c:Rotate it 90 degrees counterclockwise about the point (-3, -3) then translate it 8 units to the right
d:Translate it 8 units to the right, then reflect it over the line y=-3
Answer:
Answer choices:
a. Reflection takes it to Q2, further rotation takes it back to Q3
Incorrectb. Reflection takes it to Q2, rotation takes to Q4 with right shape.
Correctc. Rotation takes is to Q4, translation keeps in same Q but with wrong shape
Incorrectd. Translation takes it to Q4, reflection keeps it in same Q but with wrong shape
IncorrectBecause the shape is present in Q3
So reflection over x axis takes it to Q2
Then 180° rotation about origin takes it to Q4
Hence Option B is correct

Find the length of "c" to the
nearest tenth using the
Pythagorean Theorem.
Enter
Answer:
10.6
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
Where a and b = the legs and c = hypotenuse
We are given two legs and need to find the hypotenuse
Given:
Short leg (a) = 7
Long leg (b) = 8
Hypotenuse = c
Now to find the value of c we simply plug in the values of the variables into the Pythagorean theorem and solve for c
Pythagorean theorem: a² + b² = c²
a = 7, b = 8, c = c
Plug in values
7² + 8² = c²
Now solve for c
Simplify exponents
49 + 64 = c²
Add
113 = c²
Taking the square root of both sides
c = 10.6 ( rounded to the nearest tenth )
Answer:
c = 10.6
Step-by-step explanation:
[tex]h {}^{2} = p {}^{2} + b {}^{2} \\ c {}^{2} = (8) {}^{2} + (7) {}^{2} \\ c = \sqrt{64 + 49} \\ c = \sqrt{113} \\c = 10.6[/tex]
solve for X: -0.6x>3
Answer:
x < -5
Step-by-step explanation:
-0.6x > 3
=> Dividing 0.6 on both sides
=> -x > 3/0.6
=> -x > 5
=> x < -5 [When we multiply -1 on both sides the sign changes]
The solution to the inequality -0.6x > 3 is x < -5.
To solve for x in the inequality -0.6x > 3, we need to isolate x on one side of the inequality.
First, to divide both sides of the inequality by -0.6 to remove the coefficient in front of x.
Remember that when dividing or multiplying both sides of an inequality by a negative number, we need to reverse the inequality sign.
So, dividing both sides by -0.6 gives
x < 3 / -0.6
Simplifying the right side of the inequality, we have:
x < -5
Therefore, the solution to the inequality -0.6x > 3 is x < -5.

Simplify (2^-1 +5^-1)^2 *(-5/8)^-2
Answer: 1.2544
Step-by-step explanation:
2^-1 = 1/2
5^-1 = 1/5
1/2+1/5 = 7/10
(7/10)^2=49/100=0.49
(-5/8)^-2 = 64/25=2.56
(2^-1 +5^-1)^2 *(-5/8)^-2 = 0.49 * 2.56 = 1.2544
