Answer:

A newborn weighs 8 pounds at birth and gains 1.5 pounds each month for the next 3 months.

They all mostly seem right, but when a baby is first born the year is 0, so therefore it most likely seems like the first one! :)

Answer:

A

Step-by-step explanation:

To find the area of a rectangle, it is length times width (10*3x), and if it equals 40, you could just write that after the equation, and then find out that "x" would equal [tex]\frac{4}{3}[/tex]

Answer:

30x = 40 ; x ≈ 1  

Step-by-step explanation:

[tex]A^{}[/tex] = [tex]l^{}[/tex] [tex]w^{}[/tex]

[tex]l^{}[/tex] = 10 inch.

[tex]w^{}[/tex] = 3x

10(3x) = 40

30x = 40 ; x = [tex]1\frac{1}{3}[/tex] ≈ 1

Answer:

22.)

m/8 = 15/24

8×15= 120

120÷24= 5

m=5

23.)9/p = 4/48

9×48= 432

432÷4=108

p=108

24.) 10.50÷3= 3.50

thats $3.50 per pizza.

9 pizzas= $31.50

plus one pizza aka, 31.50+3.50= $35

therefore, 10 pizzas would cost $35

26.) 5/2 = d-2/4

cross multiply:

5×4=2(d-2)

20= 2(d-2) divide both sides by 2

20÷2 = 2(d-2)÷2

10= d-2 exchange places with d and 10 and change signs

-d= -2-10

-d=-12 change the sign on both sides when the variable is negative.

d=12

Answer:

ML = 6

Step-by-step explanation:

Since HIJ is a scale drawing of KML, this means the IJ and ML are corresponding sides. The corresponding sides have proportional lengths, so from HJ ≅ LK you can learn that the scale factor is 20 / 5 = 4. likewise you can confirm this with HI ≅ MK is 36 / 9 = 4.

So ML is found by dividing JI by 4 = 24/4 = 6.

Answer: The width is 12 feet, since the pool measures 10 by 12.

Step-by-step explanation:

Your aunt will need 120 square feet of land. I know this because you multiply the length by the width, it equals 120. Then I have to look for the perimeter, and I do this by adding the length twice and add the width twice. This would equal 42.

Answer and Step-by-step explanation:

4 goes into 17 four times.

Answer:

quotient-----4

Remainder---1

Step-by-step explanation:

This is basic division am I right?

Opposite of division is Multiplication

Multiplication is repeated addition

4+4+4+4=16

16+4=20 but that is greater than 17.

so quotient is 4 and remainder is 1

Answer:

x is 30° and y is 20°.

Step-by-step explanation:

In an equilateral triangle all the angles form 60°.

1) 2x = 60

x = 60/2

x = 30°.

2) 3y = 60

y = 60/3

y = 20°.

x is 30° and y is 20°.

Answer:

y=20

x=30

Step-by-step explanation:

All the angles in an equilateral triangle is equal to 60 degrees. Knowing this, we can set up the following equations:

3y=60

2x=60

3y=60

Divide both sides by 3

3y/3=60/3

y=20

2x=60

Divide both sides by 2

2x/2=60/2

x=30

I hope this helps!

Answer:

2.5 hours

Step-by-step explanation:

We are given that

Original height of candle=5 in

Every hour candle loses =8% of 5 in=0.4

According to question

[tex]5-0.4x>4[/tex]

Subtract 4 from both sides we get

[tex]5-4-0.4x>0[/tex]

[tex]1-0.4x>0[/tex]

[tex]-0.4x>-1[/tex]

[tex]0.4x<1[/tex]

Divide by 0.4 on both sides

[tex]x<\frac{1}{0.4}[/tex]

[tex]x<2.5[/tex]

x=2.5 hours

Until the candle has been burning for at least 2.5 hours, the height of her candle will be more than four inches.

Answer:

<BYX = 74 degrees

Step-by-step explanation:

The sum of angles of the adjacent sides of the trapezoid is 180 degrees

Given

<A = 106 degrees

<A + <BYX = 180

106 + <BYX = 180

<BYX = 180-106

<BYX = 74 degrees

Answer: 11.5 feet

Step-by-step explanation:

We should note that for a right angles triangle, the square of the hypothenuse equals to the square of the opposite side and its adjacent. This can be expressed as:

Let the length of Fahims shadow be x

hypotenuse² = opposite² + adjacent ²

13² = 6² + x²

169 = 36 + x²

x² = 169 - 36

x² = 133

x =✓133

x = 11.53

= 11.5 feet to nearest tenth

Answer:

P5000pesos

Step-by-step explanation:

Given data

Cost of 4 tires is P10,000 pesos

we want to find the cost of two tires

Hence if 4 tires cost P10,000 pesos.

             2 tires will cost x

cross multiply we have

4x= 10,000*2

4x= 20000

x= 20000/4

x= P5000pesos

Hence two tires will cost  P5000pesos

Answer:

a / b = 1/7

b = a x 7

a / c = 4 /1

a = c x 4

b = a x 7

= c x 4 x 7

= c x 28

b is 28 times bigger than c

b is 28 times bigger than c. The conclusion is obtained by rearranging the equations.

A ratio is an ordered pair of integers a and b, expressed as a/b, where b cannot be zero. A proportion is an equation that sets two ratios equal to each other.

The given ratio;

a: b = 1:7

a:c= 4:1

Rearrange the given ratio we obtained;

b = a × 7

a = c × 4

Put the value of a in b get;

b= c × 4 × 7

Hence, b is 28 times bigger than c.
