Amount of  blue paint used =4/5 x 9.1=7.28 pints

Amount of white  paint used=Amount of  blue paint and white paint to paint her bedroom walls -Amount of  blue paint used

=9.1-7.28=1.82 pints

Answer:

x = 20

Step-by-step explanation:

(6x - 10) and (3x + 50) are vertical angles and are congruent, then

6x - 10 = 3x + 50 ( subtract 3x from both sides )

3x - 10 = 50 ( add 10 to both sides )

3x = 60 ( divide both sides by 3 )

x = 20

Answer:

2/3

Step-by-step explanation:

There are two 4s and two 1s on the spinner. There are a total of 6 spaces. Therefore, the probability of spinning a 4 or 1 is 4/6 percent. We can simplify 4/6 to 2/3. Therefore, the answer is 2/3

Answer:

0.2

Step-by-step explanation:

Convert the walking to percent

[tex]\frac{1}{2} \times 100 = 50[/tex]

Add both skateboarding and walking

[tex]30\% + 50\%\\\\= 30 + 50\\\\= 80[/tex]

Now, subtract that from a whole percent

[tex]100 - 80 = 20\\\\20\%[/tex]

Convert it to a decimal

[tex]20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2[/tex]

Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.

Answer:

1.5 pounds. it's simply 3/8 times 4

Answer:

1.5 pounds of chocolate

Step-by-step explanation:

A single batch of ice cream takes [tex]\frac{3}{8}[/tex] of a pound of chocolate. For every added batch, we add another [tex]\frac{3}{8}[/tex] pound, or multiply [tex]\frac{3}{8}[/tex] by the number of batches.

In this case, we are making 4 batches, so we need to multiply [tex]\frac{3}{8}[/tex] by 4.

[tex]4\cdot \frac{3}{8}[/tex]

[tex]\frac{4}{1}\cdot \frac{3}{8} =\frac{3}{2}[/tex]

[tex]\frac{3}{2}=1.5[/tex]

We need 1.5 pounds of  chocolate to make 4 batches of ice cream.

Good luck ^^

The probability that the Austin orphaned pet is a dog is 32.34%.

The probability that the Austin orphaned dog is a Chihuahua is 29.38%.

Probability determines the chances that an event would happen in a random event. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that an orphaned pet in an animal shelter in Austin is a dog = total number of dogs in Austin / total number of pets

(2.76 + 2.86 + 3.44 + 2.65) / (2.76 + 2.86 + 3.44 + 2.65 + 24.50) =

11.71/36.21 = 32.34%

The probability that an orphaned dog in the same animal shelter in Austin is a Chihuahua = total number of Chihuahua in Austin /  total number of dogs in Austin

3.44 / 11.71 = 29.38%

Shaded area = Circle area - Rectangle area

Shaded area = 3.14 × (4)^2 - 5 × 6

Shaded area = 3.14 × 16 - 30

Shaded area = 50.24 - 30

Shaded area = 20.24

Shaded area = 20.2

Answer:

[tex]x = 0[/tex]

Step-by-step explanation:

Write the number in exponential form with the base of 2:

[tex] {2}^{x - 3} = {2}^{ - 3} [/tex]

Since the bases are the same, set the exponents equals.

[tex]x - 3 = - 3[/tex]

Cancel equal terms on both sides of the equation:

[tex]x = 0[/tex]

[tex]2 {}^{x - 3} = \frac{1}{8} [/tex]

To Find value of 'x'

[tex]2 {}^{x - 3} = \frac{1}{8} \\ \\ \implies2 {}^{x - 3} = 2 {}^{ - 3} \\ \\ \\ Since \: Bases \: Are \\ Equal \: We \: Need \\ To \: Evaluate \\ The \: Powers \\ \\ \implies \: x - 3 = - 3 \\ \\ \implies x = - 3 + 3 \\ \\ \implies \: x = 0[/tex]

Answer:

110-degrees

Step-by-step explanation:

these are alternate exterior angles which are equal *congruent

Answer:

Since 110° and ? are alternate exterior angles, take the 110° and subtract 180°. Remember, 180° is a straight angle. So, 180°-110°= 70°.

The missing angle is 110°, I just solved for the remaining angle to help you figure it out more easily.

Answer:

B or (8π + 12) in.2

Step-by-step explanation:

The area of the composite figure = (8π + 12) [tex]inch^{2}[/tex].

The composite figure is made up of a semicircle and an isosceles triangle.

The area of a semicircle = (1/2)π[tex]r^{2}[/tex]

radius =  4 inch

When we substitute, the area of the semicircle is

= (1/2)π[tex]\times[/tex]16

= 8π [tex]$inch^{2}[/tex]

Area of the isosceles triangle = (1/2)bh

= (1/2)(4+4)[tex]\times[/tex]3

= 12 [tex]inch^{2}[/tex]

We add the two areas to acquire the area of the composite figure to be: (8π + 12) [tex]inch^{2}[/tex]

The area of the composite figure = (8π + 12) [tex]inch^{2}[/tex].

Therefore, the correct answer is option b. (8π + 12) in.2

Answer:

  23) x=20; y=10√3

  24) x=4√2; y=8

  25) x=12; y=3+6√3

Step-by-step explanation:

Recognize that all of the triangles involved here are one of the two "special" triangles. By previous use of the Pythagorean theorem, or your familiarity with the trig functions of the "special" angles 30°, 45°, 60°, you know the following side ratios:

  45°-45°-90° triangle: 1 : 1 : √2

  30°-60°-90° triangle: 1 : √3 : 2

Using these ratios, you can solve these figures "by inspection."

__

23) x = 2((10√2)/√2) = 20

  y = √3((10√2)/√2) = 10√3

__

24) x = 4√2

  y = (4√2)√2 = 8
