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°

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.

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

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.

Answer:

a: [tex]40h+75f=800,h+f=13[/tex]

b: 5

c: 8

Step-by-step explanation:

Explanation for a: Making the equations

Assuming h is the amount of half-page ads and f is the amount of full page ads, we can create the equations [tex]40h+75f=800,h+f=13[/tex] since the total cost will be 800$, and we have a total of 13 ads.

Explanation for b: Solving for h

We can now solve for one of the variables using elimination. Let’s multiply the expression [tex]h+f=13[/tex] by -75.

[tex]-75h - 75f = -975[/tex]

Great! Now let’s add the equations.

[tex]40h + 75f = 800\\\\-75h - 75f = -975[/tex]

Adding these equations, we get

[tex]-35h = -175[/tex]

Divide both sides by -35, and we get [tex]h = 5[/tex].

Explanation for c: Solving for f

We can now substitute h inside the equation [tex]h + f = 13[/tex].

[tex]5 + f = 13\\\\f = 13-5\\\\f = 8[/tex]

Hope this helped!

(a) Let's say that h = half-page advertisement, and f = full-page advertisement.

Now It is given that there is a total of 13 advertisements present, and hence we have the first equation h + f = 13. Respectively we have the equation 40h + 75f = 800. This is represented by the following system of equations,

[tex]\begin{bmatrix}h+f=13\\ 40h+75f=800\end{bmatrix}[/tex]

(c) From here on let's solve this system for h and f. Isolating h in the first equation would give us h = 13 - f, which then can be substituted into the second equation to receive 40(13 - f) + 75f = 800. Let's solve for f --- (1)

40(13 - f) + 75f = 800,

520 - 40f + 75f = 800,

520 + 35f = 800,

35f = 280,

f = 280 / 35 = 8 full advertisements

(b) Now let's substitute this value of f back into the first equation to solve for the value of h --- (2)

h + 8 = 13,

h = 13 - 8 = 5 half advertisements

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:

Adult ticket= 7£

Child ticket= 2£

Step-by-step explanation:

Let the cost of an adult ticket be £A and the cost of a child ticket be £C.

2A +3C= 20 -----(1)

A +4C= 15 -----(2)

From (2):

A= 15 -4C -----(3)

Susbt. (3) into (1):

2(15 -4C) +3C= 20

30 -8C +3C= 20 (expand)

30 -5C= 20 (simplify)

5C= 30 -20

5C= 10

C= 10 ÷5

C= 2

Subst. C=2 into (3):

A= 15 -4(2)

A= 15 -8

A= 7

Thus, the cost of an adult ticket and a child ticket is 7£ and 2£ respectively.

= $(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:

Friend is wrong

Step-by-step explanation:

Given:

friend's claim: height of his building is more than 1.50 times the height of yours

line of sight to the top edge of the other building makes an angle of 21° above the horizontal

line of sight to the base of the other building makes an angle of 52° below the horizontal

Solution:

Let A be the height of your building is A

Let B+A his building is B higher than yours.

Let the distance between the buildings is x.  

then

tan 52 = A/x

tan 21 = B/x  

A/B = tan 52 / tan 21

      =  1.27994 / 0.38386

A/B = 3.33

(A + B) / A = 1.5 0

A/A + B/A = 1.50

1 + B/A = 1.50

B/A is basically (B/x) / (A/x)

So

1+ 3.33 / 3.33

= 4.33/3.33

= 1.3

Since 1.3 is not equal to 1.5

Hence the friend's claim is wrong.

The height of the taller building can be given in relation to the height of

the other building using trigonometric ratios.

Correct response:

The given parameters are;

Angle of elevation to the top of the other building = 21°

Angle of depression to the base of the other building = 52°

The claim of the friend = The height of his building > 1.5 × The height of the other building

Required:

To state whether the claim is right or wrong.

Solution:

Let h represent the height of the smaller building, let l represent the

distance between the two buildings, and let d represent the height by

which one building is taller than the other, we have;

l·tan(21°) = d

l·tan(52°) = h

Height of the taller building, H = h + d = l·tan(52°) + l·tan(21°)

Height of the other building = h = l·tan(52°)

Therefore;

H ≈ 1.3·h

Which gives that the taller building, H, is approximately 1.3 times the other building.

Therefore;

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.

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))

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
