Answer: z=29 so Now: Cary is 38 years old while Dan is 29 years old.
In 5 years: Cary is 43 years old while Dan is 34 years old.
Step-by-step explanation: z=29 because 29+9=38 and 38+29=67 so 38+5=43 and 29+5=34.

30°
30
x = [?]
Answer:
X=18.0
Step-by-step explanation:
It says round to the nearest tenth, which is 1 digit after the . Even though 18.02 is correct it wants you to round so X= 18.0
Final answer is X=18.0
The value of x is 18.0 rounded to nearest tenth.
What is a cosine law?Cosine law is a formula relating the length of the sides of a triangle to the cosine of one angle of the triangle.
u² = s² + t² - 2(s)(t)·cos U
We are Given Triangle with sides, 16, 30, and x, and a measure of an angle corresponding to x = 30°
Required: Value of x to the nearest tenth
Using the Cosine rule:
c² = a² + b² - 2abcos(C)
Let c = x, a = 16, b = 30
C = 30°
Thus,
c² = 16² + 30² - 2 x 16 x 30 x cos 30°
c² = 256 + 900 - 960 x 0.8660
c² = 1,156 - 831.36
c² = 324.64
c = √324.64
c = 18.017769
x ≈ 18.0 (rounded to nearest tenth)

A savings account earns 7% annual simple interest. The principal is $1,800. What is the interest
after 6 years? What is the balance?
Answer:
The interest is $756.
The balance is $2,556.
Step-by-step explanation:
I = Prt
I = $1,800 * 0.07 * 6
I = $756
The interest is $756.
$1800 + $756 = $2,556
The balance is $2,556.
What is 8/9 of 3/8 please help
Answer:
I may be wrong here because this is a topic I haven't used in quite a while, but I believe the answer is 1/3.
Step-by-step explanation:
So you take the fractions and line them up next to each other and look for any cancellations. they can only be diagonal so you can only cancel a numerator to a denominator and vice versa. Here you will see that the 8's both line up to be canceled. now you just get rid of them and put 1's. now it will look like this: 1/9 of 3/1. Here's the hardest part. The cancellations are also done for any factors, so 3 and 9 are compatible as well. You divide by the smaller number to get a whole number. If you do not get a whole number, you cannot cancel so you leave it alone. Either way, you divide 3 by 3 and 9 by 3, and now your problem should look like this: 1/3 of 1/1. 1/1 is simply just one so now you are left with a much simpler 1/3 of 1, which is 1/3. Thanks for the question.
Not sure how to answer or figure out
Answer:
112
Step-by-step explanation:
Hey There!
So remember opposite the sides given are corresponding with its opposite angle
So the corresponding angle of segment QO is angle P and the corresponding angle of segment PQ is angle O
Thus meaning that angle P and angle O are equal to 34
Now we want to find angle Q
So remember all of the angles in a triangle add up to equal 180
so we subtract the given angles (34 and 34) from 180 to find the missing angle (angle Q)
180-34-34=112
So we can conclude that angle Q = 112

if f(x)=
[tex]x - {x}^{2} [/tex]
find f(2+h) and f(x+h) where h is not equal to 0
Answer:
f(2+h)=-(h+2/3)^2+1/4
f(x+h)=-(x+h-1/2)^2+1/4
Step-by-step explanation:
1. f(2+h)=(2+h)-(2+h)^2=2+h-4-4h-h^2=-h^2-3h-2=-(h^2+3h+2)
=-(h+2/3)^2+1/4
2. Let (x+h)=a, then rewrite the equation into f(a)=a-a^2.
a-a^2=-(a^2-a)=-[(a-1/2)^2-1/4]=-(a-1/2)^2+1/4.
Insert a=x+h, f(x+h)=-(x+h-1/2)^2+1/4

In this question, the radius is 5cm thus r= 5.
Area of circle

10. A road roller takes 750 revolutions to move once to
level a playground. Find the area of the ground if the
diameter of the road roller is 168 cm and length is 2.8
m.
Answer:
Step-by-step explanation:
Use consistent units. The length of the roller is 2.8 m. The diameter is 168 cm = 1.68 m
Circumference of roller = 1.68π m
Contact area of roller = 1.68π × 2.8 = 4.704π m²
Each rotation levels 4.704π m² of the playground.
Area of playground = 750 rotations × (4.704π m²)/rotation
= 3528π m²
≈ 11,084 m²

x² = 30² - 12²x² = 756x = √756x = 27.5 ft (rounded)What is the equation of the line that passes through the points (-5,5) and has a slope of -1
Answer (assuming it can be in slope-intercept form):
[tex]y = -x[/tex]
Step-by-step explanation:
1) Use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.
Since the [tex]m[/tex] represents the slope, substitute -1 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, use the x and y values of the point (-5,5) for the formula. Substitute -5 for [tex]x_1[/tex] and 5 for [tex]y_1[/tex].
[tex]y-(5) = -1(x-(-5))\\y-5 = -1(x+5)[/tex]
2) From the above equation, isolate y to place the equation in slope-intercept form and find the final answer:
[tex]y-5=-1(x+5)\\y-5 = -x -5\\y = -x + 0\\y = -x[/tex]

20. 3x - 22 = 2x + 26
x - 22 = 26
x = 48

3x + 87 = 180
3x = 93
x = 31
22. 19x + 17x = 180
36x = 180
x = 5
27(5) = 135
23. 5x + 40 + 2x = 180
7x + 40 = 140
7x = 140
x = 20
5(20) = 100
2(20) = 40
5(20) + 40 = 100 + 40 = 140
