Which of the following expressions has a coefficient of 10 and a constant of 5?10 + 5.3
10 - 5
10x + 5
10 + 5

Answers

We have that

From the expressions

  • 10 + 5.3
  • 10 - 5
  • 10x + 5
  • 10 + 5

The correct expression is

  • 10x + 5
  • Option C

From the question we are told

Which of the following expressions has a coefficient of 10 and a constant of 5?

  • 10 + 5.3
  • 10 - 5
  • 10x + 5
  • 10 + 5

Generally

We Know That the coefficient of an expression precedes the main variable of the expression

While

The Constant is a Number that stands alone

Therefore

From the expressions

  • 10 + 5.3
  • 10 - 5
  • 10x + 5
  • 10 + 5

The correct expression is

  • 10x + 5
  • Option C

What is the surface area of the rectangular prism? 155 in² 270 in² 300 in² 310 in² rectangular prism with length labeled 4 inches, width labeled 5 inches, and height labeled 15 inches155 in² 270 in² 300 in² 310 in²

Answers

The surface area of rectangular prism is $310\,\text{i}{{\text{n}}^{\text{2}}}$.

What is surface area of rectangular prism?

The surface area of the rectangular prism is defined as the sum of the area of lateral faces and rectangular bases.

So, the formula of surface area of rectangular prism is,

$\text{SA = }2lh+2hw+2lw$

Where, SA is the surface area, l is the length, w is the width of the rectangle and h is the height.

It is given that,

l = 4 in

w = 5 in

h = 15 in

Put all the given values in the above formula and solve it.

So,

$\text{SA = }2lh+2hw+2lw$

     $=2\left( 4\cdot 15 \right)+2\left( 15\cdot 5 \right)+2\left( 4\cdot 5 \right)$

     $=120+150+40$

$\therefore \,\,\text{SA}=310$

Hence, the correct answer is  optiond that is $310\,\text{i}{{\text{n}}^{\text{2}}}$.

hey guys.... please help me with this question ,chapter lines and angles and i will mark u the brainiest if u answer it 1st (6 marks)

Answers

Answer:

Step-by-step explanation:

Alternate angles:When two lines are crossed by another line the pair of angles on opposite sides of the transversal is called alternate angles.  

Theorem 1:If a transversal intersects two Parallel Lines then each pair of alternate interior angles is equal.

Theorem 2 :If a transversal intersects two lines such that a pair alternate interior angle is equal then the two lines are parallel.  

SOLUTION:

Given:  ∠AGE=126°

∠AGE=∠GED=126∘ [alternate interior angles]

 (ii) ∠GED=∠GEF+∠FED=126∘

∠GEF + 90° =126°

(GIVEN that EF⊥CD)  

∠GEF=126°−90°=36°

∠GEF=36°

(iii) ∠CEG+∠GED=180°

(GIVEN ∠GED=126∘)

∠CEG+126° =180°

∠CEG=180° −126°

∠CEG=54°

∠FGE=∠CEG= 54°     (alternate angles)
