Answer: 3:5
Step-by-step explanation:
So, taking the ratio of the time taken by Henry to the time taken by Gavin is: (36 mins/ 60 mins) = (36/60) = 3:5 [Taking minutes as the common unit for both of the cases.] Thus the ratio is 3:5 in simplest form.

Find the acute angles of a right triangle if:

B) one of them 2 times
C) The ratio of their values is 2:3.
help!!!!!!!!!
hurry up please and tell me about everything please
can someone help me im gonna be late pleasee do it for me my mom gonna kill me if i will got f
Answer:
A angles are 15 and 75 B. angles are 30 and 60 C. angles are 36 and 54
Step-by-step explanation:
Remember that the two acute angles of a right triangle = 90
A one angle = x ; the other angle = 60 + x so 60 +x + x = 90
60 + 2x = 90; 2x = 30; x = 15 one angles; the other angle is 60 + 15 = 75
B. One angle = x ; the other angle = 2x so x + 2x = 90
3x = 90 ; x = 30 one angle; the other angle s 2x = 2(30) = 60
C 2 : 3 means 2x:3x
One angle = 2x ; the other angle = 3x ; so 2x + 3x = 90
5x = 90; x = 18 this is what x is equal to. Now the find the angles:
one angle is 2x meaning 2(18) = 36 and the other angle is 3x meaning 3(18) = 54.
To check this answer one angle to the other angle is represented by the ratio 2:3; 36:54 = 2:3 Reduced!

naomi has earned $54 mowing lawns the past two days .She worked 2.5 hours yesterday and 4.25 hours today .if naomiis paid the same amount for every hour she works ,how much does she earn per hour to mow lawns
Answer:
8$ per hour
Step-by-step explanation
First, we need to find how many hours Naomi worked, total.
Simply add [tex]2.5+4.25=6.75[/tex]
Now we know that Naomi earned 54$ over 6.75 hours.
All we have to do to find the hourly rate is divide [tex]54/6.75=8[/tex]
Naomi earns 8$ per hour mowing lawns.
Answer:
$8
Step-by-step explanation:
Set up an equation with the payrate ($/hr) as the unknown.
2.5 × R + 4.25 × R = 54
6.75 × R = 54 ; R = [tex]\frac{54}{6.75}[/tex] = 8

Millie and Molly’s ages add up to 19 years Millie is three years older than Molly how old are they
Answer:
Millie is 11. Molly is 8.
Step-by-step explanation:
Step 1: Subtract 3 from 19. The reason why you do this is to make sure that you don't have an extra 3 lying in there for the next few steps.
19-3=16
Step 2: Divide 2 from 16. You do this because there are two sisters.
16÷2=8
8 will then become Molly's age
Step 3: Add 3 to 8. This will give you Millie's age because she is 3 years older than Molly.
3+8=11
In conclusion, Millie is 11 and Molly is 8.

Answer:
m∠EFD = 90°
m∠EHF = 127°
m∠HFG = 56°
m∠G = 71°
m∠E = 19°
Step-by-step explanation:
From inspection of the given diagram, line segment GD is a straight line and m∠EFG= 90°.
Angles on a straight line sum to 180°:
⇒ m∠EFG + m∠EFD = 180°
⇒ 90° + m∠EFD = 180°
⇒ 90° + m∠EFD - 90° = 180° - 90°
⇒ m∠EFD = 90°
Angles on a straight line sum to 180°:
⇒ m∠EHF + m∠FHG = 180°
⇒ m∠EHF + 53° = 180°
⇒ m∠EHF + 53° - 53° = 180° - 53°
⇒ m∠EHF = 127°
From inspection of the given diagram, m∠EFH and m∠HFG form a right angle:
⇒ m∠EFH + m∠HFG = 90°
⇒ 34° + m∠HFG = 90°
⇒ 34° + m∠HFG - 34° = 90° - 34°
⇒ m∠HFG = 56°
Interior angles of a triangle sum to 180°:
⇒ m∠HFG + m∠GHF + m∠G = 180°
⇒ 56° + 53° + m∠G = 180°
⇒ 109° + m∠G = 180°
⇒ 109° + m∠G - 109° = 180° - 109°
⇒ m∠G = 71°
Interior angles of a triangle sum to 180°:
⇒ m∠E + m∠EFH + m∠EHF = 180°
⇒ m∠E + 34° + 127° = 180°
⇒ m∠E + 161° = 180°
⇒ m∠E + 161° - 161° = 180° - 161°
⇒ m∠E = 19°

Answer:
22)43300000, 23)~7, 24)~20
Step-by-step explanation:
22)6.48*10^(7)-(2.15*10^(7))=4.33*10^7 (or 43300000)
23)2.95*10^6=2950000, 2.15*10^7=21500000, 21500000/2950000=~7
24)1.3*10^9=130000000, 1300000000/64800000=~20
Answer:
Step-by-step explanation:
22. You can write these exponents out if it makes it easier to understand, then convert back into exponential form.
6.48 x 10⁷ = 64800000 France
2.15 x 10⁷ = 21500000 Australia
Subtracting Australia from France = 43300000
Converting back to exponential would be 4.33 x 10⁷
But if you notice both number have the exponent of 10⁷. Since these are both the same, you can just subtract the whole number for Australia from the number for France 6.48 - 2.15 = 4.33
then just put the exponent on the end. 4.33 x 10⁷
23. Again it might be easier to convert to standard numbers first.
Area of Australia = 2.95 x 10⁶ or 2950000
Population = 2.15 x 10⁷ or 21500000
So population per square mile would be population divided by area.
21500000 / 2950000 = 7.3 people per square mile
Now if you look at the two numbers, the exponents are only different by 1. You can easily make the population have the same exponent as the area by moving the decimal place of the whole number
Population 2.15 x 10⁷ is the exact same as 21.5 x 10⁶. Now since both number have the same exponents, you can cancel those out and just divide the whole numbers. 21.5 divided by 2.95 which also equals 7.3.
24. You can look at this the same way.
China population 1.3 x 10⁹ is 1300000000
France population 6.48 x 10⁷ is 64800000
Dividing China by France you get about 20.1 which means China is about 20.1 times great in population than France.
If you use the same method as in question 23, you can change the population of China so the exponent matches that of France.
1.3 x 10⁹ is exactly the same as 130 x 10⁷
Again, since both exponents are the same, you can cancel them out and just divide the whole numbers.
130 / 6.48 which also equals about 20.1

What are the values of y and z?
Answer:
y = 70°
z = 40°
Step-by-step explanation:
The two red marks in the sides HF and HG of the triangle means that it is an isosceles triangle, and it means that it have the two angles in the base with the same value, so the angle y have to be 70°. Now, the sum of the 3 internal angles of a triangle is always 180°. We have two angles with 70, so 70+70= 140°. 180-140 = 40°
The two figures are similar to find the ratios (shaded to non-shaded) of perimeters
perimeter of non-shaded part = 7
perimeter of shaded part = 9
so ratio of shaded to non shaded is =
shaded:non shaded = 9:7 = 9/7
so option b is correct
Answer:
I think it's 9/7 for the nonshaded one and the shaded one is 81/49

Write the equation of the function whose graph IS
shown.
y = ____ (x + ____)^2 + ____
Answer:
y=1(x-5)^2+3
Please correct me if i am wrong.
Step-by-step explanation:
We know that the turning point of a graph in the form a(x+p)^2+q is (-p,q) so,
TP(5,3) means that p=-5, q=3.
To solve a for the function y = a(x-5)^2+3, we can substitute one of the points we know lie on the graph for x and y so,
Substitute (8,12) into y=a(x-5)^2+3,
12=a(8-5)^2+3
12=9a+3
9=9a
a=1,
So substitute in a,
y=1(x-5)^2+3

Step-by-step explanation:
as there are only 3 types of discontinuity overall : A, B and C.
there is no fourth, so D is out.
to check we use x = 2 in both equations and see, if and how the 2 connect or disconnect at that point.
5x + 4, x = 2
5×2 + 4 = 14
this is finite and a well-defined number.
2 - x, x = 2
2 - 2 = 0
this is again finite and well-defined.
but it is different from 14 above.
there is no multiplication factor or so that causes special values. so, there is no removable discontinuity. A is out.
none of the values at the point go to infinity, so there is no infinite discontinuity. B is out.
but yes, the functional value Suendenbock suddenly jumps at the point from 0 to 14 without any connection.
so, yes, it is a jump. C is right.

Determine the x and y intercepts of the graph of 3x + 4y = 24
Answer:
Step-by-step explanation:
3x + 4y = 24
Find the x intercept by solving intersecting the graph of f(x) or y with
y=0 (which is the x-axis)
4y= -3x+24, subtract 3x from both sides of the equation
y = (-3x/4) +6, divide both sides by 4
if y=0 then
(-3x/4) +6 = 0 , subtract 6 from both sides
-3x/4 = -6, multiply both sides by 4
-3x = -24 , divide both sides by
x= 8, so the x intercept is at (8, 0)
the general formula of a line is y=mx+b , where b is the y-intercept
since our equation is y = (-3x/4) +6 then y intercept is at (0, 6)

A 10 -foot ladder is leaning on a tree. The bottom of the ladder on the ground at a distance of 6 feet from the base of the tree. The base of the tree and the ground form a right angle as shown.
What is the distance, in feet, between the ground and the top of the ladder?
The distance, in feet, between the ground and the top of the ladder is 8 feet.
The diagram formed will be a right triangle having the hypotenuse, adjacent and opposite sides
To get the distance, in feet, between the ground and the top of the ladder, we will use the Pythagoras theorem as shown:
hyp² = opp² + adj²Given the following sides
length of ladder = hyp = 10footdistance from ladder to the base = adjacent = 6 feetSubstitute the given parameters into the formula to have:
10² = opp² + 6²
opp²=100 - 36
opp² = 64
opp = 8feet
Hence the distance, in feet, between the ground and the top of the ladder is 8 feet.
