Given that the triangles shown below are simiar, what is the value of x?

Answer:

B) 2:5

Step-by-step explanation:

it should be 2:5 since the girls are only 10, while the boys are 25 in number which makes their ratio bigger.

Answer:

y = - [tex]\frac{5}{2}[/tex] x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, - 5) and (x₂, y₂ ) = (2, 0)

m = [tex]\frac{0+5}{2-4}[/tex] = [tex]\frac{5}{-2}[/tex] = - [tex]\frac{5}{2}[/tex] , then

y = - [tex]\frac{5}{2}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, 0 )

0 = - 5 + c ⇒ c = 0 + 5 = 5

y = - [tex]\frac{5}{2}[/tex] x + 5 ← equation of line

Weight limit of an elevator = 1800 pounds

Average weight of each person who comes in the elevator = 160 pounds

Quantity of items with them = 3 pounds

Let the number of people who can ride the elevator at one time be x.

Which means :

[tex] =\tt 160x + 3 = 1800[/tex]

[tex] = \tt160x = 1800 - 3[/tex]

[tex] = \tt160x = 1797[/tex]

[tex] =\tt x = \frac{1797}{160} [/tex]

[tex] =\tt x = 11[/tex]

Thus, number of people who can enter the elevator is 11.

▪︎Therefore, the correct option is (b) 11.

Answer:250

Step-by-step explanation:

150/3 =50

50x5=250

The quantity of strawberries in jar is 250 gram.

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorise ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.

Given the Jam is made from sugar and strawberries in a ratio of 3:5,

ratio of sugar to strawberries = 3/5

sugar in jam = 150 gram

let quantity of strawberries  be x gram

the ratio of sugar to strawberries = 150/x

since both ratios are in proportions so

3/5 = 150/x

x = 150 * 5/3

x = 250 gram

Hence the quantity of strawberries is 250 grams.

Answer:

1/81

Step-by-step explanation:

P(H,H,H,H)=16/81

fourth root of 16/81= 2/3

so the probability of getting tails would be 1/3

probability of getting 4 tails would be:

P(T,T,T,T)=(1/3)^4

=1/81

The probability of getting 4 tails when the coin is thrown 4 times is 1/81

We have:

P(Head 4 times) = 16/81

This means that:

P(Head)^4 =  16/81

Take the 4th root of both sides

P(head) = 2/3

The probability of a tail is calculated as:

P(tail) = 1 - P(Head)

This gives

P(tail) = 1 - 2/3

P(tail) = 1/3

When thrown 4 times, we have:

P(tail)^4 = (1/3)^4

P(tail) = 1/81

Hence, the probability of getting 4 tails when the coin is thrown 4 times is 1/81

Answer:

  3 19/30 hours

Step-by-step explanation:

The given fractions will have 30 as a common denominator.

  12/30 + 1 5/30 + 2 2/30 = (1 +2) +(12 +5 +2)/30 = 3 19/30 . . . hours

Jenny ran 3 19/30 hours this week.

Answer:

Step-by-step explanation:

Total hours that Jenny ran = 3.63 hours.

Step-by-step explanation:

Jenny ran on Tuesday for = 2/5 hours or 0.4 hours.

Time consumed to run on Thursday = 11/6 hours or 1.83 hours.

Time consumed to run on Saturday = 21/ 15 hours or 1.4 hours.

Here, the total hours can be calculated by just adding all the running hours. So the running hours of Tuesday, Thursday, and Saturday will be added to find the total hours.

Total hours that Jenny ran = 0.4 + 1.83 + 1.4 = 3.63 hours.

Answer:

Step-by-step explanation:

a). tan(75°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

                  = [tex]\frac{11}{k}[/tex]

    k = [tex]\frac{11}{\text{tan}(75)}[/tex]

    k = 2.947

    k = 2.95 cm

b). cos(52°) = [tex]\frac{16}{s}[/tex]

    s = [tex]\frac{16}{\text{cos}(52)}[/tex]

    s = 25.988

    s ≈ 25.99 cm

c). sin(5°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

               = [tex]\frac{16.1}{q}[/tex]

    q = [tex]\frac{16.1}{\text{sin}(5)}[/tex]

Answer:

 4.50

Step-by-step explanation:

4 = Whole number. 1 = Numerator. 2 = Denominator. To get 4 1/2 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.

The decimal form of  4 and 1/2  is 4.5

Decimal is a fraction written in a unique form. The dot notation is used to represent the fraction form.

Therefore, 4 and 1/2 in decimal form is represented as follows;

Mixed fraction = 4  1 / 2

Improper fraction = 9 / 2

decimal form of  1 / 2 = 0.5

Therefore, 4 1 / 2 = 4.5
