Answer:

52

Step-by-step explanation:

14+13= 27+2=29+23=52

The value of the numerical expression 12 ⋅ (14 + 13)² + 23 will be 8771.

When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.

The expression is given below.

⇒ 12 ⋅ (14 + 13)² + 23

Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction are all part of the PEMDAS formula. To answer the problem properly and accurately, this rule must be followed.

⇒ 12 ⋅ (14 + 13)² + 23

⇒ 12 ⋅ (27)² + 23

⇒ 12 ⋅ 729 + 23

⇒ 8748 + 23

⇒ 8771

The value of the numerical expression 12 ⋅ (14 + 13)² + 23 will be 8771.

Answer:

Tan x = 1

Step-by-step explanation:

As a tangent of 90° is impossible, x must be the measure of both of the 45° angles.

If we assume 3 is the length of one of the shorter legs, it is also the length of the other of the shorter leg

Tangent x = Opposite/Adjacent = 3/3 = 1

Answer:

A

Step-by-step explanation:

[tex]\frac{x^2+x-6}{x-7} \leq 0\\[/tex]

hence numerator and denominator are of opposite sign.

case1 .

let x²+x-6≥ 0

and x-7<0

x²+x≥6

x²+x+1/4≥6+1/4

(x+1/2)²≥25/4

(x+1/2)²≥(5/2)²

|x+1/2|≥5/2

x+1/2≥5/2

x≥5/2-1/2

x≥2

or

x+1/2≤-5/2

x≤-5/2-1/2

x≤-3

also x-7<0

x<7

combining

x≤-3 or 2≤x<7

case 2.

x²+x-6<0

and x-7≥0

x²+x<6

x²+x+1/4<6+1/4

(x+1/2)²<25/4

|x+1/2|<5/2

so -5/2 <x+1/2<5/2

-5/2-1/2<x<5/2-1/2

-3<x<2

also x-7≥0

so x≥7

combining

we get no vlaue satisfying both the values.

Hence rejected.

Answer:

Parallel: The slope is the same as in the previous equation. So, y=3x+b. To find the value of b, you plug in the given point, 2=3(3)+b, b=-7. So the equation is y=3x-7.

Perpendicular: The slope is the negative reciprocal when an equation is perpendicular. The negative reciprocal of -2 is 1/2. So, y=1/2x+b. To find the value of b, you plug in the given point, -1=1/2(2)+b, -1=1+b, b=-2. So the equation is y=1/2x-2.

Answer:

Step-by-step explanation:

The given line equations are written in "slope-intercept" form.

  y = mx + b . . . . . . . . . m is the slope; b is the y-intercept

If we solve this equation for b, we find ...

  b = y - mx

This is useful for completing the equation of the line through a given point when the slope is known.

A parallel line will have the same slope as the given line. The given line has a slope (x-coefficient) of 3. We can find the "b" of the line through the desired point as ...

  b = y -3x

  b = 2 -(3)(3) = -7

The equation of the parallel line is ...

  y = 3x -7

__

A perpendicular line will have a slope that is the opposite reciprocal of the slope of the line it is perpendicular to. Here, the given line has a slope of -2, so the perpendicular line will have a slope of ...

  -1/(-2) = 1/2

Then the y-intercept is ...

  b = y -(1/2)x

  b = -1 -(1/2)(2) = -2

And the equation of the perpendicular line is ...

  y = 1/2x -2

__

The attached graph shows the original lines as dashed lines, and the corresponding desired lines as solid lines in the same color.

Answer:

  9

Step-by-step explanation:

For studs 16" O.C., Chalberg will need 9: one at the beginning of each of the 16" spaces in the 96" width of the wall, and one at the end. That's a total of 6+1 = 7 studs.

The top and bottom edges of the wall are each 8', so will require 1 more board each.

The total number of boards Chalberg needs is 9.

Answer:

∠A = 90°

Step-by-step explanation:

∠A = 3∠B

∠B = 1/2 × (∠C), this can also be written as ∠C = 2∠B

∠A + ∠B + ∠C = 180, because there are 180° inside a triangle

Write angle A, B and C in terms of angle B:

3 ∠B + ∠B + 2 ∠B = 180

Simplify:

6 ∠B = 180

∠B = 180 ÷ 6 = 30°

Work out angle A:

∠A = 3∠B = 3 × 30°

∠A = 90°

Her score in computer to get a proportionally weighted average of 46% will be 134.

The total score for both subjects = 200 + 300 = 500

Since the proportionally weighted average is 46%, then her score will be:

= 46% × 500

= 0.46 × 500

= 230

Since she had 32% for her statistics test, which was out of a total of 300. Her score will be:

= 32% × 300

= 0.32 × 300

= 96

Therefore, her score in computer will be:

= 230 - 96

= 134

if six spiders can spin 6 webs in 6 min then 100 spiders can spin 100 webs in 100 min then multipy by 2 and you get 200

The amount of time that 100 spiders can spin 200 webs will be 12 minutes.

Algebra is the study of graphic formulas, while logic is the manipulation of those signs.

Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction is referred to as the PEMDAS rule. To answer the problem properly and accurately, this rule is applied.

If 6 spiders can spin 6 webs in 6 minutes. Then the 1 spider can sin one web in six minutes. So, the 100 spiders can spin 100 webs in 6 minutes.

Then the 100 spiders can spin 200 webs in 12 minutes.

Answer:

8. 75 days

Step-by-step explanation:

You work for 10.5 days 7.5 hrs each day painting the house = it takes 78.75 hours to paint the house.

If you work 9 hours a day: 78.75/9 = 8.75 days

If she does the same job for 9 hours. Then the number of days will be 8.75 days.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

Karen paints her house in ten and a half days, working seven and a half hours every day.

If she does the same job for 9 hours. Then the number of days is given as,

D x 9 = 10.5 x 7.5

9D = 78.75

D = 78.75 / 9

D = 8.75 days

If she does the same job for 9 hours. Then the number of days will be 8.75 days.
