Answer:

0 < x < 9

Step-by-step explanation:

Mary's age = x

Twice of Mary's age = 2x

Emily's age = (2x + 3) (we are told Emily is 3 years older than twice of Mary's age)

Given that the sum of their ages is > 30, we have the following expression:

[tex] (2x + 3) + x [/tex] > 30

Let's simply:

[tex] 2x + 3 + x [/tex] > 30

[tex] 3x + 3 [/tex] > 30

Subtract 3 from both sides

[tex] 3x + 3 - 3 [/tex] > [tex] 30 - 3 [/tex]

[tex] 3x [/tex] > [tex] 27 [/tex]

Divide both sides by 3

[tex] \frac{3x}{3} [/tex] > [tex] \frac{27}{3} [/tex]

[tex] x [/tex] > [tex] 9 [/tex]

Therefore, the inequality that represents Mary's possible age is: 0 < x < 9

Answer:

Step-by-step explanation:

To find the length of the hypotenuse of QPO we must first find the value of x

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

QO² = QP² + OP²

That's

( x + 6)² = 5² + ( x + 5)²

x² + 12x + 36 = 25 + x² + 10x + 25

Group like terms

x² - x² + 12x - 10x = 50 - 36

2x = 14

Divide both sides by 2

x = 7

The hypotenuse of QPO is (x + 6)

Substitute the value of x into the expression

That's

Answer:

[tex]\Huge \boxed{\mathrm{D.} \ 13}[/tex]

[tex]\rule[225]{225}{2}[/tex]

Step-by-step explanation:

The triangle is a right triangle.

We can use Pythagorean theorem to solve for the value of x.

[tex]OP^2 +PQ^2 =OQ^2[/tex]

[tex](x+5)^2 +5^2 =(x+6)^2[/tex]

Simplifying both sides.

[tex]x^2 +10x+50=x^2 +12x+36[/tex]

Subtracting x², 10x and 36 from both sides.

[tex]14=2x[/tex]

Dividing both sides by 2.

[tex]7=x[/tex]

Letting x = 7 for the length of the hypotenuse.

[tex]\Longrightarrow \ 7+6 \\\\\\ \Longrightarrow \ 13[/tex]

Answer: Answer is in steps

Step-by-step explanation:

A)  To find p(46) input the 46 into the equation and solve

   p(46) = 61.41 + 2.32(46)  

   p(46) = 168.13

B) This means that if the female's femur is 46 in length then that female will be 168.13 centimeters tall.

========================================================

Method 1

Use your calculator to find the decimal version of each fraction

We see that 0.20 is the smallest decimal of the list, so 1/5 is the smallest fraction of the list.

----------------------------

Method 2

To compare fractions, we need to get all of the denominators to the same value. A good target is the lowest common denominator (LCD)

In this case, the LCD is 100

The last fraction has the smallest denominator, so 1/5 is the smallest.

Step-by-step explanation:

The distributive property is as follows :

[tex]a(b+c)=ab+ac[/tex] ....(1)

We need to solve [tex]24(\dfrac{d}{4}-5)=156[/tex] using distributive property

Applying property (1) on the LHS of given equation

Taking a = 24, b = d/4 and c = -5

So,

[tex]24(\dfrac{d}{4}+(-5))=156\\\\24\times \dfrac{d}{4}+24\times (-5)=156\\\\6d-120=156\\\\6d=156+120\\\\6d=276\\\\d=\dfrac{276}{6}\\\\d=46[/tex]

So, we get the value of d as 6 using distributive property.

A= 0,-3

D= -4,-3

C= 0,4

B= 3,3

Answer:

Step-by-step explanation:

Let the height of their oldest sister isabella be z centimeters. Roger is x centimeters tall and Olivia is y centimeters tall.

If their oldest sister, Isabella, is 25 centimeters shorter than the double of the sum of Roger and Olivia's height, this can be expressed as shown;

First let us get the sum of Roger and Olivia's height;

The sum of Roger and Olivia's height = (x+y)cm

The double of the sum of their ages = 2* (x+y)cm = 2(x+y)cm

Now if Isabella, is 25 centimeters shorter than the double of the sum of their ages, the expression will be [2(x+y)-25]

Since the height of isabella is z, the expression that model isabella's height will be expressed as z =[2(x+y)-25]cm

Answer:

(2 (4 x + 5), -(3 x + 25))

Step-by-step explanation:

Simplify the following:

(12 x - 4 x + 3 + 7, 5 x + 2 x - 3 x - 7 x - 18 - 13 - 2 + 8)

Grouping like terms, 12 x - 4 x + 3 + 7 = (12 x - 4 x) + (3 + 7):

((12 x - 4 x) + (3 + 7), 5 x + 2 x - 3 x - 7 x - 18 - 13 - 2 + 8)

12 x - 4 x = 8 x:

(8 x + (3 + 7), 5 x + 2 x - 3 x - 7 x - 18 - 13 - 2 + 8)

3 + 7 = 10:

(8 x + 10, 5 x + 2 x - 3 x - 7 x - 18 - 13 - 2 + 8)

Factor 2 out of 8 x + 10:

(2 (4 x + 5), 5 x + 2 x - 3 x - 7 x - 18 - 13 - 2 + 8)

Grouping like terms, 5 x + 2 x - 3 x - 7 x - 18 - 13 - 2 + 8 = (-7 x + 2 x - 3 x + 5 x) + (8 - 13 - 18 - 2):

(2 (4 x + 5), (-7 x + 2 x - 3 x + 5 x) + (8 - 13 - 18 - 2))

-7 x + 2 x - 3 x + 5 x = -3 x:

(2 (4 x + 5), -3 x + (8 - 13 - 18 - 2))

8 - 13 - 18 - 2 = -25:

(2 (4 x + 5), -25 - 3 x)

Factor -1 out of -3 x - 25:

Answer: (2 (4 x + 5), -(3 x + 25))

Answer:

[tex]f(x)=2x+3[/tex]

Step-by-step explanation:

So we know that:

[tex]f(1)=5 \text{ and } f(3)=9[/tex]

In other words, we have 2 coordinates: (1,5) and (3,9).

With this, we can figure out the slope. Let (1,5) be x₁ and y₁ and let (3,9) be x₂ and y₂. The slope formula is:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute:

[tex]m=\frac{9-5}{3-1}\\m=4/2=2[/tex]

So, the slope is 2.

Now, use the point-slope form to figure out the y-intercept. The point-slope form is:

[tex]y-y_1=m(x-x_1)[/tex]

For consistency, let's continue to use (1,5) as x₁ and y₁. Now, we can use 2 as m. Thus:

[tex]y-(5)=2(x-1)[/tex]

Distribute:

[tex]y-5=2x-2[/tex]

Add 5 to both sides:

[tex]y=2x+3[/tex]

So:

[tex]f(x)=2x+3[/tex]

And that's our equation :)

Answer: ∠ABE=20°

Step-by-step explanation:

∵ AB=BC

∴ ΔABC is a isosceles triangle

∵ ∠A=30

∴ ∠C=30

∵ The interior angle sum of triangle is 180°

∵ ∠A+∠B+∠C=180

    30+∠B+30=180

           ∠B+60=180

                  ∠B=120 (∠ABC)

∵ ∠EBD+∠ABE+∠ABC=linear pair

∴∠EBD+∠ABE+∠ABC=180°

                  4x+2x+120=180

                        6x+120=180

                                6x=60

                                  x=10

∠ABE=2x=2(10)=20°

= $(260101/62500)

As a mixed number =

$[tex]4\frac{10101}{62500}[/tex]

Step-by-step explanation:

Cost of making a computer component = $4.161616

= $4 + $0.161616

6 numbers after the decimal , hence

0.161616 × 1000000/1000000

= 161616/1000000

= 10101/62500

We are told in the question to write the repetiting decimal cost as a fraction and as a mixed number

$4 + $0.161616 = $4 + 10101/62500

As a fraction

= $[(4 × 62500) + 10101]/62500

=$260101/62500

As a mixed number = [tex]$4\frac{10101}{62500}[/tex]

Answer:

Josephine

Step-by-step explanation:

2 criteria was given to pass an exam:

1. At least, a mean mark of 40% must be achieved in the exam consisting of 4 papers

2. Score at least, 33% in each paper.

From the table given, and considering these two criteria, James definitely didn't pass the examination. He scored below 33% in one of the 4 papers. James scored 30% in Maths

Calculated the mean score for John and Josephine to determine if they meet the first criteria of having at least a mean score of 40%.

Mean score of John = (35 + 36 + 42 + 44) ÷ 4 = 39.25%

Mean score for Josephine = (60 + 55 + 38 + 75) ÷ 4 = 57%

Josephine passed the examination because she had a mean score of 57%, and also scored 33% and above in each test.

Answer: 6

Step-by-step explanation:

Given: Gomez has 30 cans of regular soda and 18 cans of diet soda.

He wants to create some identical refreshment tables that will operate during the football game and doesn't want any sodas left over.

Then, the greatest number of refreshment tables that Gomez can stock = GCD (30,18).

Since, 30=  2 x 5 x x 3

18= 2 x 3 x 3

GCD (30,18) = 2 x 3 = 6

Hence, the greatest number of refreshment tables that Gomez can stock is 6.

Answer:

63

Step-by-step explanation:

-1,5,15,29,41,63

between the 2nd term and first term, we add 6

between the 3rd and 2nd, we add 10

between 4th and 3rd, we add 14

between 5th and 4th, we add 12

to get the next term, we add 22 to the fifth tern which is 63

this is how to get the 4th term 6 interval was added to 8 making 14 and to get the fifth, then add 2 to the difference of 10 making 12. 29+12=41..so to get the last term 14 was added to 8 making 22 and therefore 41+22=63

Answer:

153 cm^2

Step-by-step explanation:

The area is given by

A = b*h

   = 17*9

    =153 cm^2

Answer:

Step-by-step explanation:

A=(b1+b2/2)h

The formula is area= base 1 plus base 2 over 2 times the height.

The two bases are 17 cm.  Let's add that in our formula.

A=(17+17/2)h

17+17= 34.  Since 34 is over 2 in the parentheses, let's simplify that first.

A=(34/2)h

A=(17)h, because 34 divided by 2 is 17

The height, h, is 9 cm.  Let's subsitute that into h.

A=(17)9

17 times 9 equals 153, so the area is 153² cm.  :)
