Emi buys 14 balloons. Three are red, four are white, and the rest are blue. Hat is the ratio of blue balloons to the total numbe

Deffense [45]

Answer:

The ratio of blue balloons to the total number of balloons is 1:2.

Step-by-step explanation:

Given:

Total number of balloons = 14

Number of red balloons = 3

number of white balloons = 4

Number of the blue balloons are the rest remaining.

We need to find the the ratio of blue balloons to the total number of balloons.

Solution:

First we will find the number of blue balloons.

Now we know that;

Number of the blue balloons can be calculated by Total number of balloons minus sum of Number of red balloons and number of white balloons.

framing in equation form we get;

Number of the blue balloons = $14-(3+4) =14 -7 =7$

Now to find the ratio of blue balloons to the total number of balloons we will divide Number of the blue balloons from Total number of balloons.

framing in equation form we get;

Ratio = $\frac{7}{14} = \frac{7\times1}{7\times2}= \frac{1}{2}$

Hence the ratio of blue balloons to the total number of balloons is 1:2.

Lines c and d are parallel. Parallel lines c and d are cut by transversals s and t. Clockwise from top left, the angles formed b

lys-0071 [83]

Answer:

Options (1), (2) and (5) are true.

Step-by-step explanation:

Option (1). m∠1 = (2x + 10)°

lines c and d are the parallel lines and t is a transverse.

Therefore, m∠1 = (2x + 10)° [corresponding angles]

This option is true.

Option (2). m∠3 = 87°

Since ∠3 and angle having measure equal to 87° are the vertical angles therefore, both the angles will be equal in measure.

This option is true.

Option (3). m∠2 = (2x + 10 + 5x - 1)°

m∠2 = (5x - 1)° [Since both the angles are interior alternate angles]

Therefore, this option is not true.

Option (4). m∠1 + m∠2 = m∠3

(5x - 1) + (2x + 10) + 87 = 180° [Sum of liner angles at a point is 180°]

7x + 96 = 180

7x = 180 - 96

x = $\frac{84}{7}$

x = 12

Therefore, m∠1 = (2x + 10) = 34°

m∠2 = (5x - 1) = 59°

m∠3 = 87°

For the given relation,

m∠1 + m∠2 = m∠3

34 + 59 = 87

93 = 87

Not true.

Therefore, this option is not correct.

Option (5). 87 + 2x + 10 + 5x - 1 = 180°

True.

Since these angles are the linear angles so the sum of all angles = 180°

Therefore, the given option is correct.

Options (1), (2) and (5) are the true.

Help pleaseee!!!!!!!

Crank

Answer:

1. 180

2. 300

3. 480

Step-by-step explanation:

1. Since 30% of 600 (or 0.3 * 600) = 180, the 1st blank is 180.

2. 50% of 600 (also easy to just think of one half {1/2}) = 300

3. Because 180 + 300 = 480

hope this helps:)

Find the distance between the points c ( 6, 5) and D(-3, 1),

svet-max [94.6K]

Answer:

see explanation

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (6, 5) and (x₂, y₂ ) = (- 3, 1)

d = $\sqrt{(-3-6)^2+(1-5)^2}$

= $\sqrt{(-9)^2+(-4)^2}$

= $\sqrt{81+16}$

= $\sqrt{97}$ ≈ 9.85 ( to 2 dec. places )
