Triangle A’ B’ C’ is a dilation of ABC. What is AB?

Answer:

1m/s²

Step-by-step explanation:

Acceleration is the change in velocity of a body with respect to time.

Acceleration = Change in velocity/time

Acceleration (a) = final velocity(v)-initial velocity(u)/time(t)

Given parameters:

final velocity v = 4.4m/s

initial velocity u = 1.2m/s

time taken = 3.2s

Required

Acceleration

Substitute the given parameters into the formula to get the acceleration

Acceleration = 4.4 - 1.2/3.2

Acceleration = 3.2/3.2

Acceleration = 1m/s²

Therefore the boy acceleration is 1m/s²

Answer:

x = -5

Step-by-step explanation:

-4x + -3 = 17

-4x - 3 = 17

-4x - 3 + 3 = 17 + 3

-4x = 20

-4x/-4 = 20/-4

x = -5

Hope this helps!

Answer:

x=-5

Step-by-step explanation:

-4x+-3=17

First add 3 to both sides.

-4x=20

Then divided by -4

Note: Negatove divided by postive is negative.

20÷(-4) = -5

So.

x=-5

Answer:

7,200 pieces are baked in four weeks

Step-by-step explanation:

Here in this question, we are interested in knowing the number of cookies baked in four weeks.

Okay, here we know that there are 6 varieties with 5 dozen of each kind baked everyday.

A dozen is 12 , this means that 5 dozens will be 5 * 12 = 60

Now, 60 pieces of each variety is baked per day. The total number of cookies baked per day is thus 60 * 6 = 360 pieces

Now, a week is just 5 days here. Since we are not considering weekends. Now, the number of days in 4 weeks will be 4 * 5 = 20 days

Since 360 pieces are baked in a day and we have the baking for 20 days in four week, the number of cookies baked is simply the product of the number of pieces and the number of days.

That will be 20 * 360 = 7200 pieces

Answer:

1/11 is a repeating decimal

9/100 is a terminated decimal

Step-by-step explanation:

Properties of the fractional part of 100 can be determined as percentages.  Using this, we can see that 9/100 will result in .09 or 9%.

Properties of the fractional part of 11 can be seen to be a non-divisible number resulting in a repeating decimal equivalent.  So, 1/11 will result in .090909 ad infinitum.

Note, that odd divisors that are not multiples of 5, typically will result in a repeating decimal.

Cheers.

Answer:

knots           mi/h

5 knots         5.7539 mi/h

10 knots        11.5078 mi/h

Step-by-step explanation:

Given

knots           mi/h

5 knots         _mi/h

10 knots        _mi/h

Required

Fill in the gap

From the question, we understand that

[tex]1 knot = 1.15078mi/h[/tex]

Solving (a): 5 knots

Recall:

[tex]1 knot = 1.15078mi/h[/tex]

Multiply both sides by 5

[tex]5 * 1 knot = 1.15078mi/h * 5[/tex]

[tex]5\ knots = 1.15078mi/h * 5[/tex]

[tex]5\ knots = 5.7539\ mi/h[/tex]

Solving (b): 10 knots

Recall:

[tex]1 knot = 1.15078mi/h[/tex]

Multiply both sides by 10

[tex]10 * 1 knot = 1.15078mi/h * 10[/tex]

[tex]10\ knots = 1.15078mi/h * 10[/tex]

[tex]10\ knots = 11.5078mi/h[/tex]

Hence; The complete table is

knots           mi/h

5 knots         5.7539 mi/h

10 knots        11.5078 mi/h

Step-by-step explanation:

Answer:

1) 37

2) 23

3) x = 4

4) 58

Step-by-step explanation:

1) 15 + 22 = 37

2) 54 - 31 = 23

3) 6x + 1 + x + 7 = 36

7x + 8 = 36

7x = 28

x = 4

4) 3x + 10 + 47 = 9x - 39

57 = 6x -39

96 = 6x

16 = x

     x = 16

    EF = 3x + 10

    EF = 3(16) + 10

Answer:

1. 69°

2. 97°

3. 145°

4. 150°

5. 128°

6. 74°

Step-by-step explanation:

To find the angle measure of the missing angle, we have to note that the angle measures of a quadrilateral will all equal up to be 360°.

If we know 3 out of the 4 angles and the sum of the angles, we can add up the angles we know then subtract that from 360.

Number 1:

[tex]87+112+92=291[/tex]

[tex]360-291=69[/tex]

Number 2:

[tex]124+71+68=263[/tex]

[tex]360-263=97[/tex]

Number 3:

[tex]95+46+74=215[/tex]

[tex]360-215=145[/tex]

Number 4:

[tex]72+49+89=210[/tex]

[tex]360-210=150[/tex]

Number 5:

[tex]69+65+98=232[/tex]

[tex]360-232=128[/tex]

Number 6:

[tex]77+123+86=286[/tex]

The value of x = 10 and y = 6 if the scale factor of A to B is 1:2.

Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions of the actual figure or object.

We have been given that the scale factor of A to B is 1:2.

Here one length of triangle A is 5 inch

For finding y, we have to divide 12 by 2

⇒ x = 12/2 = 6 inch

Here one length of triangle B is 12 inch

For finding x, we have to multiply 2 to 5

⇒ y = 2×5 = 10 inch

Therefore, the value of x = 10 and y = 6.

Answer:

x = 0

Step-by-step explanation:

10 + 10 = -2(4x - 10)

20 = -8x + 20

0 = -8x

0/-8 = x

0 = x

Answer: x=0

Step-by-step explanation:

Given

10+10=-2(4x-10)

Combine like term

20=-2(4x-10)

Distributive property (REMEMBER you need to change signs when it is negative outside)

20=-8x+20

Subtract 20 on both sides (subtractive property of equality)

-8x=0

Divide -8 on both sides (division property of equality)

x=0

Answer:

24 and 21

Step-by-step explanation:

the ratio of their ages is 8 : 7 = 8x : 7x ( x is a multiplier )

In 6 years

8x + 6 : 7x + 6 = 10 : 9

Express the ratio in fractional form

[tex]\frac{8x+6}{7x+6}[/tex] = [tex]\frac{10}{9}[/tex] ( cross- multiply )

9(8x + 6) = 10(7x + 6) ← distribute parenthesis on both sides

72x + 54 = 70x + 60 ( subtract 70x from both sides )

2x + 54 = 60 ( subtract 54 from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Thus

Tony = 8x = 8 × 3 = 24

Vihaan = 7x = 7 × 3 = 21

Answer:

Tanay's age = 24yrs

Vihaan's age = 21yrs

Step-by-step explanation:

let the ages of tanay and vihaan be8x,7x

After 6yrs tanay's age=8x+6

vihaan's age=7x+6

a/q=8x+6/7x+6=10/9

=9(8x+6)=10(7x+6)

=72x+54x=70x+60

72x-70x=60-54

2x=6

x=3

tanay's age=8×3=24yrs

vihaan's age=7×3=21yrs

Answer:

d is correct

Step-by-step explanation:

Given

10(30x - 5y) = - 40y + 600 ( divide both sides by 10 )

30x - 5y = - 4y + 60 ( add 5y to both sides )

30x = y + 60 ( subtract 60 from both sides )

30x - 60 = y → d

∠Q = ∠U = 60°

Step-by-step explanation:

Construct the figure QSUT with your own dimensions as long as QR ≅ RU and SR ≅ RT , where R is the common midpoint.

I choose QR = 4 cm and SR = 5  cm

Then measure ∠Q and ∠U to check if they are equal.

I got that ∠Q = ∠U = 60° proving that;

∠Q ≅ ∠U

Answer:

216 people

Step-by-step explanation:

Given:

2.5 feet² is occupied by 1 person

Dimension of room = 216 in × 360 in

Required:

No. of people that would occupy the room

SOLUTION:

Step 1:

Convert the dimensions of the room from in to ft

Note: 1 foot = 12 inches

216 inches = [tex] \frac{216}{12} = 18 ft [/tex]

360 inches = [tex] \frac{360}{12} = 30 ft [/tex]

Step 2: calculate area of the room.

Area of the room = 30*18 = 540 ft²

Step 3: calculate the no. of people the room will contain.

2.5 ft² will contain one person

Therefore, 540 ft² will contain: [tex] \frac{540}{2.5} = 216 people [/tex]

Answer:

x=4/5

Step-by-step explanation:

9 - |12-20x| = 5

=>-|12-20x|= 5-9

=>-|12-20x|=-4

=>12-20x=-4

=>-20x=-4-12

=>-20x=-16

=>x=16/20

=>x=4/5

We can conclude the following information:

Every 3 hours the temperature changes.

At 9 AM, the temperature was -1.6°F:

9 AM = -1.6°F =>

Between 9 AM and noon, the temperature rose 6.6°F:

12 PM = -1.6 + 6.6 = 5°F =>

Between noon and 3 PM, the temperature increased by 2.8°F:

3 PM = 5 + 2.8 = 7.8°F =>

Between 3 PM and 6 PM, the temperature went down 10.5°F:

6 PM = 7.8 - 10.5 = -2.7°F

What was the temperature at 6 PM?

-2.7°F

Answer:

Step-by-step explanation:

Let x=0.121212.....

     99x=12

         x=12/99

so 0.121212... is equal to 12/99
