Answer:

128

Step-by-step explanation:

2 to the power of 7 means you multiply 2 seven times over

2*2*2*2*2*2*2 = 4*2*2*2*2*2= 8*2*2*2*2= 16*2*2*2= 32*2*2= 64*2 = 128

Answer:

1. y=kx

2. y=60

Step-by-step explanation:

y is directly proportional to x

y=kx

Find Constant K, when y=30 & x=6

Make K the subject of the formula first

K=y/x

K=30/6

k=5

When k is 5, x is 12, find y

y=kx

y=5×12

y=60

Answer:

0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture

Step-by-step explanation:

Probability:

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Arrangments of x elements:

The total number of arrangments of x elements is given by:

[tex]A_{x} = x![/tex]

Desired outcomes:

Standing in alphabetical order, so only 1 possible outcome, which means that [tex]D = 1[/tex]

Total outcomes:

Arrangments of 5 people, so

[tex]T = A_{5} = 5! = 120[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{1}{120} = 0.0083[/tex]

0.0083 = 0.83% probability that the boys will stand in alphabetical order from left to right in the picture

Answer:

the value of x is -12 and the value of y is -4

Step-by-step explanation:

Given;

x = 3y   ----- (1)

[tex]\frac{x}{2} + 2y = -14[/tex]   ----(2)

Substitute the value of x into equation (2)

[tex]\frac{3y}{2} + 2y = -14\\\\multiply \ through \ by \ 2\\\\3y + 4y = -28\\\\7y = -28\\\\divide \ through \ by \ 7 \\\\y = -4\\\\solve \ for \ x\\\\x = 3y\\\\x = 3(-4)\\\\x = -12[/tex]

Thus, the value of x is -12 and the value of y is -4

Step-by-step explanation:

Answer:

B(–1, 4)

Step-by-step explanation:

We want to find a point P(x,y).

Since it is on the directed line segment AB in the ratio 1:3, it means that:

[tex]P - A = \frac{1}{1+3}(B-A)[/tex]

So

[tex]P - A = \frac{1}{4}(B-A)[/tex]

We apply this to both the x-coordinate and y-coordinate of P.

x-coordinate:

x-coordinate of A: -3

x-coordinate of B: 5

x-coordinate of P: x

So

[tex]P - A = \frac{1}{4}(B-A)[/tex]

[tex]x - (-3) = \frac{1}{4}(5 - (-3))[/tex]

[tex]x + 3 = \frac{1}{4} \times 8[/tex]

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

[tex]x = -1[/tex]

y-coordinate:

y-coordinate of A: 1

y-coordinate of B: 13

y-coordinate of P: y

So

[tex]P - A = \frac{1}{4}(B-A)[/tex]

[tex]y - 1 = \frac{1}{4}(13 - 1)[/tex]

[tex]y - 1 = \frac{1}{4} \times 12[/tex]

[tex]y - 1 = 3[/tex]

[tex]y = 4[/tex]

So the correct answer is given by option B.

If hole for a bird feeder post is 3 feet deep, the top of the post needs to be at least 5 feet above the ground. Then  x-3≥5  is the inequality that represents the required length of the post.

a relationship between two expressions or values that are not equal to each other is called 'inequality.

Given,

The hole for a bird feeder post is 3 feet deep,

the top of the post needs to be at least 5 feet above the ground

We need to find the inequality that represents the required length of the post.

Let x be the length of the post.

As, it is deeper then it has negative three.

There is given atleast, so it should be greater than or equal to.

x-3≥5

Hence, x-3≥5  is the  inequality that represents the required length of the post.

Answer:

My answer would be: Tim is incorrect, because more than one triangle can be drawn with the given information.

Given:

Isosceles triangle and has a 70° angle.

An isosceles triangle is a triangle that has 2 congruent angle. Since all interior angle must have a sum of 180°, the possible angles of an isosceles triangle with a 70° angle are:

1) 180° - 70° = 110°

110° / 2 = 55°

Angles are 70°-55°-55°

2) 180° - 70° = 110°

110° - 70° = 40°

Angles are 70°-70°-40°

The given information can create 2 isosceles triangle. Thus, Tim is wrong in his claims.
