Answer:

It took Riley 9 hours to clean the garage.

Step-by-step explanation:

With the information provided, you can say that the amount Riley earns for cleaning the garage is equal to the price per hour for the number of hours it takes to clean the garage, which can be express as:

x=4.25y, where:

x is the amount Riley earns for cleaning the garage

y is the number of hours it takes to clean the garage

Now, you can replace x with $38.25 that is the amount that Riley earned and you can solve for y to find how long it took her to clean the garage:

38.25=4.25y

y=38.25/4.25

x=9

According to this, the answer is that it took Riley 9 hours to clean the garage.

Answer:

6 * 10^2

Step-by-step explanation:

Simplify : (4.2×10^7)÷(7×10^4)

(4.2 × 10^7) / (7 × 10^4)

From indices : 10^a ÷ 10^b = 10^(a - b)

(4.2 / 7) * 10^(7-4)

0.6 * 10^3

= 6 * 10^2

Hence, (4.2×10^7)÷(7×10^4) = 6 * 10^2

Answer:

12 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Put 5 in fraction form ( [tex]\frac{5}{1}[/tex] ) and multiply it by [tex]\frac{5}{2}[/tex]

[tex]\frac{5}{1}[/tex]×[tex]\frac{5}{2}[/tex] = [tex]\frac{25}{2}[/tex]   now simplify  to 12 [tex]\frac{1}{2}[/tex]

The time at which the distance of both the riders will be same is required.

At 5 minutes they both would have covered 20 miles.

The given lines are [tex]y=4x[/tex] and [tex]y=3x+5[/tex]

So,

[tex]4x=3x+5\\\Rightarrow 4x-3x=5\\\Rightarrow x=5[/tex]

Finding [tex]y[/tex]

[tex]y=4x\\\Rightarrow y=4\times 5=20[/tex]

At [tex]x=15[/tex] the distance covered by both riders is [tex]y=20[/tex]

Answer:

72 cm²

Step-by-step explanation:

Area of a ∆ = 1/2 × b × h

b = 12 cm

h = 12 cm

Area = 1/2 × 12 × 12

= 1/2 × 144

= 72 cm²

Answer:

24 cm

Step-by-step explanation:

The altitude from the centre to the chord is 5 cm and bisects the chord.

The radius of the circle is 26 cm ÷ 2 = 13 cm

There is a right triangle formed with legs 5 and x ( x is half the chord )

The hypotenuse is the radius, then using Pythagoras' identity

x² + 5² = 13²

x² + 25 = 169 ( subtract 25 from both sides )

x² = 144 ( take the square root of both sides )

x = [tex]\sqrt{144}[/tex] = 12

Then

length of chord = 2x = 2 × 12 = 24 cm

Answer:

Step-by-step explanation:

The  chord, if the ends connected with the center, form an isosceles triangle with two sides being a radius of the circle.

We have:

From the triangle we get:

The length of the chord is 24 cm

Answer: 720

Step-by-step explanation:

From the question, we are informed that cthe researches counted 400 turtles, of which 20 were marked. This implies that 20/400 = 1/20 were marked.

If the researchers wanted to track the reptile population around a lake, and the researchers marked 36 turtles, the estimate of the total population will then be:

1/20 × x = 36

x/20 = 36

x = 20 × 36

x = 720

The turtle population is 720

Answer:

4 Liters

Step-by-step explanation:

Maria uses 8 flavor packets to make punch for a party. Each packet is mixed with 500 milliliters of water. How many liters of punch does Maria make?

Step 1

1 flavor packet = 500 ml

8 flavor packets = x ml

Cross Multiply

x ml = 8 × 500 ml

x ml = 4000 ml

Step 2

We convert from Milliliters to Liters

1 milliliters = 0.001 liter

4000 milliliters = x liter

Cross Multiply

x liters = 4000 milliliters × 0.001 liter/ 1 milliliters

x liters = 4 liters

Therefore, Maria can make 4 liters of punch

Answer:

- [tex]\frac{8}{7}[/tex] tanx

Step-by-step explanation:

Using the identities

secx = [tex]\frac{1}{cosx}[/tex] , cscx = [tex]\frac{1}{sinx}[/tex] , tanx = [tex]\frac{sinx}{cosx}[/tex]

Given

[tex]\frac{8secx}{-7cscx}[/tex]

= [tex]\frac{\frac{8}{cosx} }{\frac{-7}{sinx} }[/tex] ← multiply numerator/ denominator by sinx

= [tex]\frac{8\frac{sinx}{cosx} }{-7}[/tex]

= - [tex]\frac{8}{7}[/tex] tanx

Answer:

∠A = ∠D  (**but very important Δ ABC has to be congruent to Δ DEF)

Answer:313.1

Step-by-step explanation:

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

6 x 10 /5  = 60/ 5

Thus, the answer to 6 divided by 5/10 in fraction form is:

60 /5

To make the answer to 6 divided by 5/10 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

60 / 5 = 12

The answer is rounded to the nearest two decimal points if necessary.

60/5 can be simplified to 12/1.

12/1 is an improper fraction and should be written as 12.

After dilation of ΔABC, the length of B'C' = 8m and ∠A' = 28°.

Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.

When the triangle undergoes dilation, the length of its sides gets multiplied by 1/2 (dilation factor) but the angles remain the same ( since, the shape has to remain same).
