Answer:

Area of the penny = 30 square inches

Step-by-step explanation:

Out triangle-shaped pennants on the first day of school. If each pennant has a base of 5 inches and a height of 12 inches, what is the area of each pennant in square inches?

The pennant is triangular in shape. Hence:

Area of a Triangle = 1/2× Base × Height

Base of the pennant = 5 inches

Height = 12 inches

Area of the pennant = 1/2 × 5 inches × 12 inches

= 30 square inches

Answer:

13x

Step-by-step explanation:

Answer:

13x

Step-by-step explanation:

So we need to make the denominator equal in order to collect like terms.

25x^2/5x+8x^2/x =?

Denominator needs to be 5x so multiply the second quotient by 5.

25x^2/5x + 40x^2/5x = ?

=65x^2/5x

=13x^2/x      <---- x^2/x is like 2-1 which is exponent 1, x to the exponent 1 is x

=13x

Your answer is 13x

Answer:

B/second option

Step-by-step explanation:

The first option is wrong because you make 30 meatballs in 30 mins but then 30 meatballs in 20 mins. If it was constant then in 20 mins you make less meatballs.

The last option is wrong because if bacteria triples, then that is exponential, not constant change.

Only the middle option makes sense. The rate of change is $35 for each hour!

please give thanks by clicking the heart button! :)

The example that has a constant rate of change is

An electrician earns $50 for the first hour plus $35 for every additional hour.

Option B is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x = 5 is an equation.

We have,

30 minutes = 30 meatballs

20 minutes = 30 meatballs

This is not a constant rate of change.

$35 for every additional hour.

This means,

1 hour = $35

This is a constant rate of change,

Bacteria triples every hour.

This is an exponential function.

Example:

Number of bacteria initially = 2

Number of bacteria after 1 hour = 3 x 2 = 6

Number of bacteria after 2 hours = 3 x 6 = 18

This is not a constant rate of change.

Thus,

An electrician earns $50 for the first hour plus $35 for every additional hour is a constant rate of change.

Answer:

[tex]\bold{\angle B = 51^\circ}[/tex]

Step-by-step explanation:

Given a [tex]\triangle ABC[/tex] such that [tex]\angle A[/tex] is the largest.

[tex]\angle A[/tex] is equal twice of [tex]\angle B[/tex]

[tex]\angle C[/tex] is 10 more than one third of [tex]\angle B[/tex]

To find:

Measurement of [tex]\angle B[/tex].

Solution:

Let [tex]\angle B =x^\circ[/tex]

As per question statement:

[tex]\angle A = 2\times \angle B=2x^\circ[/tex]

[tex]\angle C = \dfrac{1}{3}\angle B +10= \dfrac{1}{3}x +10 ^\circ[/tex]

Using the angle sum property of a triangle i.e. sum of all the three internal angles is equal to [tex]180^\circ[/tex].

[tex]2x+x+\dfrac{1}{3}x+10 = 180\\\Rightarrow \dfrac{10}{3}x =170\\\Rightarrow x = 51^\circ[/tex]

Therefore, the answer is:

[tex]\bold{\angle B = 51^\circ}[/tex]

Answer: umm jus look up what a histogram is

Step-by-step explanation:

Answer:

∠ 1 = 70°, ∠ 2 = 140

Step-by-step explanation:

110° and the adjacent angle inside the triangle are supplementary, then

angle = 180° - 110° = 70°

Since 2 sides of the triangle are congruent, then the triangle is isosceles

Thus the 2 base angles are congruent, then

∠ 1 = 70°

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ 2 is an exterior angle of the triangle, thus

∠ 2 = 70° + 70° = 140°

Answer:

The answer is x=2

Step-by-step explanation:

8(4-x)=7x+2

32-8x=7x+2

-8x+32=7x+2

8x+32-7x=7x+2-7x

-15x+32=2

-15x+32-32=2-32

-15x=-30

-15x/-15=-30/-15

x=2

Answer:

2

Step-by-step explanation:

First, do the distributive property: 32-8x =7x+2

Next, get the variable to one side: 32-8x(-7x)=7x(-7x)+2

Then, subtract 32 from both sides to isolate the variable: -15x+32(-32)=2(-32)

Finally, we divide -30 by -15 : -15x= -30  

x= 2
