Answer:

∠A=-4X+170°

Step-by-step explanation:

IN triangle some of all the angle is 180°

hence in triangle ABC

∠A+∠B+∠C=180°

GIVEN ∠A=X+20° ∠B=3X-10°

HENCE ∠A+3X-10°+X+20°=180°

∠A+4X+10°=180°

∠A=-4X+170°

The market research department at a manufacturing plant determines that 30% of the people who purchase the plant's product durin

4vir4ik [10]

Answer:

number of people who will purchase next month = 250

the number of people who will purchase in 2 month = 325

Step-by-step explanation:

Data provided in the question:

people who purchase the plant's product during any month will not purchase it the next month = 30%

therefore, people who purchase the plant's product during any month will purchase next month = 70%

people who do not purchase the product during any month will purchase it the next month = 20%

Total number of people = 1000

Number of people who purchased this month = 100

Number of people who did not purchase = 1000 - 100 = 900

therefore,

the number of people who will purchase next month

= 70% of 100 + 20% of 900

= 0.70 × 100 + 0.20 × 900

= 70 + 180

= 250

now,

the number of people who will purchase in 2 month

= 70% of (number of people who will purchase next month) + 20% of (number of people who did not purchase next month)

= 70% of 250 + 20% of (1000 - 250)

= 0.70 × 250 + 0.20 × 750

= 175 + 150

= 325

Determine any data values that are missing from the table, assuming that the data represent a linear function.

Stells [14]

Answer:

Fill in the blank with 14

Step-by-step explanation:

Given

The attached table

Required

Fill in the gap

Since, the table represents a linear function.

The first step is to calculate the slope of the table

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Where

$(x_1,y_1) = (1,2)$

$(x_2,y_2) = (2,6)$

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{6 - 2}{2 - 1}$

$m = \frac{4}{1}$

$m=4$

The equation of the table is calculated next as:

$y - y_1 = m(x - x_1)$

This becomes

$y - 2 = 4(x - 1)$

$y - 2 = 4x - 4$

Solve for y

$y = 4x - 4+2$

$y = 4x -2$

To fill in the blank;

The value of x is 4

So, substitute 4 for x in $y = 4x -2$

$y = 4 * 4 - 2$

$y = 16 - 2$

$y = 14$

Higher Order Thinking a carpenter plans to extend the length of rectangular desk by 7 feet. Let x represent the desk's original

abruzzese [7]

Answer:

d. 9x + 63 and 63 square feet

Step-by-step explanation:

Given

Original

$Length = x$

$Width = 9$

Extended

$Length = x + 7$

$Width = 9$

$Area = 9(x + 7)$

Required

Determine an expression and the value of the extended area

First, we calculate the area of the original desk

$A_1 = x * 9$

$A_1 = 9x$

From the given parameters, we have:

$Area = 9(x + 7)$ --- area of the new surface

Open bracket

$Area = 9x + 63$

The area of the new surface is the summation of the area of the original desk and the area of the extended portion (E)

So:

$Area = A_1 + E$

Make E the subject

$E= Area - A_1$

$E= 9x + 63 - 9x$

$E= 63$

Hence, the area of the extended portion is 63
