Answer:

102

Step-by-step explanation:

x = 180 - (4x - 2) - 78

x = 180 - 4x + 2 -78

5x = 180 + 2 - 78

5x = 104

x = [tex]20\frac{4}{5}[/tex].

So, angle UTW is 4 *  [tex]20\frac{4}{5}[/tex] - 2 +  [tex]20\frac{4}{5}[/tex] = 5 *  [tex]20\frac{4}{5}[/tex] - 2 = 104 - 2 = 102

Answer:

C

Step-by-step explanation:

Well, the area or a circle is pi r^2. The radius is 5. 5 squared is about 25. 25 times pi is roughly 78.5. So the best answer is C.

Step-by-step explanation:

for 12

Perimeter (P)

= 2( L + B)

= 2 ( 500 + 300)

=2 * 800

= 1600 cm

For 13

Area

= L * B

= 500 * 300

= 150000 cm²

Step-by-step explanation:

Since Promethean board is rectangle in shape,

So Given,

Dimensions of that board = 500 cm by 300 cm

Hence, Perimeter of the board = 2(l+b)

= 2(500cm + 300cm) = 2 × 800cm

= 1600cm (Ans)(i)

Therefore, area of that board = l × b

= 500cm × 300cm

[tex] = 150000 {cm}^{2} (ans)(ii)[/tex]

Answer:

210 candy bars

85 gum

Step-by-step explanation:

$200=0.75cb+0.50gum

cb+gum=295

gum=295-cb

substitute

$200=0.75cb+0.50(295-cb)

$200=0.75cb+147.5-0.50cb

$200=0.25cb+147.5

0.25cb=52.5

cb=210

gum=295-210=85

Step-by-step explanation:

step 1. if k is a zero then (x - 1) is a factor of 4x^3 + 23x^2 - 34x + 7.

step 2. we "can" use long division but synthetic division is easier!

step 3. 1 4 23 -34 7

4. 4. 27. -7.

4 27. -7. 0 (must get 0)

step 4. so the factors are (x - 1)(4x^2 + 27x - 7).

step 5. please note if you multiply these factors together you will get the original polynomial!

Answer: It's A if not put B

Step-by-step explanation:

Since correlative conjunctions are used to connect parts of a sentence with equal value, we only need to use a comma when two independent clauses are being connected with correlative conjunctions.Correlative conjunctions include pairs such as “both/and,” “either/or,” “neither/nor,” “not/but” and “not only/but also.

This is the image of the graph you determine if that's perpendicular.

Perpendicular definition - In elementary geometry, the property of being perpendicular is the relationship between two lines which meet at a right angle. The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.

Answer: x= 47 (If that says 3x+2)(the picture is a little blurry)

Step-by-step explanation:

Linear pairs of angles sum to 180.

37+(3x+2) =180

Combine like terms

39+ 3x = 180

Subtract 39 from both sides

3x = 141

Divide both sides by 3

x= 47

Answer:

2.5x>-25

x>-25/2.5

x>-10

x<-10

Answer:

x < -10

Step-by-step explanation:

-2.5x > 35-10

-2.5x > 25

-2.5x > 25/-2.5

x > -10

You have to switch the sign because you divided it by negative

x<-10

Answer:

the gross monthly income last month is $3,318.92

Step-by-step explanation:

The computation of the gross monthly income last month is shown below:

= Total sales × commission percentage

= $82,968 × 4%

= $3,318.92

hence, the gross monthly income last month is $3,318.92

We simply multiplied the total sales with the commission percentage

Step-by-step explanation:

depending on what x is, you multiply x by 50 and add 200, since 200 is the start up fee and the constant. the 50 dollars per month is a variable, since the more months you own the plan, the more money it would cost.

Answer:

3w−11v+12u

Step-by-step explanation:

2u−4v+10u+2w+w−7v

2u-4v+10u+2w+1w-7v

2u−4v+10u+2w+1w−7v

2u+10u−4v−7v+2w+1w

2u+10u −4v−7v +2w+1w

^12u         ^-11v     ^3w

12u -11v+3w

3w−11v+12u

​

The perimeter of the triangle is represented by the expression 3w−11v+12u.

Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees. The perimeter of the triangle is defined as the sum of all the sides of the triangle.

Given that a triangle has side lengths of (2u-4v)(2u−4v) centimeters, (10u+2w)(10u+2w) centimeters, and (w-7v)(w−7v) centimeters. The perimeter of the triangle is calculated by adding all the sides of the triangle.

E = 2u−4v+10u+2w+w−7v

E = 2u-4v+10u+2w+1w-7v

E = 2u−4v+10u+2w+1w−7v

E = 2u+10u−4v−7v+2w+1w

E = 2u+10u −4v−7v +2w+1w

E = 12u -11v+3w

E = 3w−11v+12u

Therefore, the perimeter of the triangle is represented by the expression 3w−11v+12u.
