Answer: 200 x .40 = 80 (there are 80 pennies)

200 - 80 = 120

120 x .25 = 30 (there are 30 quarters)

200×40%= 80 pennies so 200-80=120 and 25% of 120 is 30 so 30 quarters. you can use the % sign when using a calculator or move the decimal over twice like this 200×.40=80 if a % sign is unavailable

Answer:

See explanation

Step-by-step explanation:

Consider the sequence \dfrac{1}{32},\ \dfrac{1}{8},\ \dfrac{1}{2}, 2,\ 8,...

Rewrite it as

b_1=\dfrac{1}{32},\\ \\b_2=\dfrac{1}{8},\\ \\b_3=\dfrac{1}{2},\\ \\b_4=2,\\ \\b_5=8...

The points on the coordinate plane are

(1,b_1),\ (2,b_2),\ (3,b_3),\ (4,b_4),\ (5,b_5),... (see attached graph).

Since

4=\dfrac{b_2}{b_1}=\dfrac{b_3}{b_2}=\dfrac{b_4}{b_3}=\dfrac{b_5}{b_4}..., given sequence is geometric.

AB is a straight line workout the size of angle X
Hoochie [10]

The x value will be 109°. The straight line formed a 180° angle. Solving the equation yields the angle.

<h3>What are supplementary angles?</h3>

Supplementary angles are two angels whose sum is 180°. When a straight line intersects a line, two angles form on each of the sides of the considered straight line.

Those two-two angles are supplementary angles in two pairs. That is, if two supplementary angles are adjacent to each other, their exterior sides form a straight line.

The straight line formed a 180° angle. The resulting equation is as follows:

⇒x+42°+29°=180°

⇒x=109°

Hence, the value of the x will be 109°

The complete question is:

AB is a straight line.

Work out the size of angle x.

How do you the equation of the line that passes through point (-3,2) and is parallel to the line formed by the equation y = 4x +
hjlf

Answer:

y = 4x + 14

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 4x + 7 ← is in slope- intercept form

with slope m = 4

• Parallel lines have equal slopes , then

y = 4x + c ← is the partial equation

to find c substitute (- 3, 2 ) into the partial equation

2 = - 12 + c ⇒ c = 2 + 12 = 14

y = 4x + 14 ← equation of parallel line
