Answer: 25 red marbles

Step-by-step explanation:

Fraction of yellow marbles = 1/3

Fraction of blue marbles = 1/4

Fraction of red marbles = 1 - (1/3 + 1/4) = 5/12

Therefore, the number of red marbles that are there in the bowl would be:

= 5/12 × 60

= 25 red marbles

Answer:

x + y = 162 and x = 2y - 6

Step-by-step explanation:

Let the total wins be x

Let the total loss be y

If a baseball team's total wins and losses for one season is 162, this can be expressed as;

x + y = 162 ....... 1

If the number of wins is 6 less than 2 times the number of losses, this is expressed as;

2 times the number of losses = 2y

6 less than 2 times the number of losses = 2y - 6

Now, If the number of wins is 6 less than 2 times the number of losses this is expressed as;

x = 2y - 6 .... 2

Hence the required system of equation are;

x + y = 162 and x = 2y - 6

Answer:

  d.

Step-by-step explanation:

The triangle is a right triangle. Statements a-c are true.

There is no necessary relationship between angles F and G. Statement d is false.

Answer:

DF=22.57

DG=26

Step-by-step explanation:

sinF/DG=sinD/FG

sin75/DG=sin48/20

DG*sin48/sin48=20*sin75/sin48

DG=26

D^+F^+G=180(sum of int. angles of triangle)

G^=180-48-75

G^=57

sinG/DF=sinD/FG

sin57/DF=sin48/20

DF*sin48/sin48=20*sin57/sin48

DF=22.57

The value of DF and DG is 22.57 units and 25.9956 units respectively.

Given to us,

∠D = 48°,

∠F = 75°,

FG = 20,

According to sine rule, in a triangle the length of a side of the triangle and the angle opposite to it is always in ratio. therefore,

[tex]\dfrac{A}{sin\alpha}= \dfrac{B}{sin \beta}= \dfrac{C}{sin\gamma}[/tex]

So,

[tex]\dfrac{DF}{sin (G)}= \dfrac{FG}{sin (D)}= \dfrac{GD}{sin(F)}[/tex],

For ∠G,

∠D + ∠F + ∠G = 180°,

48° + 75° + ∠G = 180°,

∠G = 180° - ( 48° +75°),

∠G = 57°,

Now using the sine rule,

[tex]\dfrac{DF}{sin (G)}= \dfrac{FG}{sin (D)}= \dfrac{DG}{sin(F)}\\\\\\\dfrac{DF}{sin (57)}= \dfrac{20}{sin (48)}= \dfrac{DG}{sin(75)}\\\\\\\dfrac{DF}{sin (57)}= \dfrac{20}{sin (48)}\\\\DF = 22.57\ units\\\\\\ \dfrac{20}{sin (48)}= \dfrac{DG}{sin(75)}\\\\DG = 25.9956\ units[/tex]

Hence, the value of DF and DG is 22.57 units and 25.9956 units respectively.

Substitute these values into our formula:

[tex] \sf P = 2(3n - 9) + 2(n + 5) [/tex]

Since the perimeter is equal to 56, the value of n satisfies the following equality:

Answer:

The domain and the range of the function represented by the set of ordered pairs are {-6, -3, -1, 5} and {5, 2, 0, -4}

Step-by-step explanation:

In any set of ordered pairs,

Let us solve the question

∵ The set of ordered pairs is {(-6, 5), (-3, 2), (-1, 0), (5, -4)}

∵ The first number in each ordered pair represents x

∴ x = -6, -3, -1, 5

∵ The set of x is the domain of the function

∴ The domain of the set of ordered pairs = {-6, -3, -1, 5}

∵ The second number in each ordered pair represents y

∴ y = 5, 2, 0, -4

∵ The set of y is the range of the function

∴ The range of the set of ordered pairs = {5, 2, 0, -4}

The domain and the range of the function represented by the set of ordered pairs are {-6, -3, -1, 5} and {5, 2, 0, -4}

9.9

Step-by-step explanation:i odn't have an explanation but try it i know it is right

Using the formula, it is found that the distance between the two points (−7, 1) and (0, −6) is of 9.9 units.

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

In this problem, the points are (−7, 1) and (0, −6), hence:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]D = \sqrt{(0 - (-7))^2+(-6-1)^2}[/tex]

[tex]D = \sqrt{98}[/tex]

Answer:

Option (C)

Step-by-step explanation:

If a point is dilated by a scale factor of 'k' about the origin,

Rule for the dilation,

(x, y) → (kx, ky)

By this rule, if ΔABC is dilated to form image triangle as ΔA'B'C',

A(-2, -2) → A'[2×(-2), 2×(-2)]

B(-1, 2) → B'[2×(-1), 2×(2)]

C(2, 1) → C'[2×(2), 2×(1)]

Therefore, scale factor of the dilation of the dilation will be k = 2

Option (C) will be the answer.

Answer:

Step-by-step explanation:

(3y - 2z) 5.

so

3ytimes 5 = 15y (can multiply variable number with non variable number in this case)

and -2z times 5 =-10z

=

15y-10z

The expression  (3y - 2z) 5 can be written, by using the Distributive Property as 15y - 10z.

This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding the results together.

Given expression:

(3y - 2z) 5,

The above expression can be written by using Distributive Property as,

[tex]A (B + C) = AB + AC[/tex]

(3y - 2z) 5 = 3y × 5 - 2z × 5

(3y - 2z) 5 = 15y - 10z

Therefore, the expression  (3y - 2z) 5 can be written, by using the Distributive Property as 15y - 10z.
