Answer:

SO 28 new t shirts.

Each drawer can hole 6 tshirts.

How many drawers needed.

Now this is a division problem, how many “6 tshirts” can fit into 28 t shirts.

Something like that.

Anyways its 28/6 or 28 ÷ 6 = 4 remainder 4

4 r 4

Now we need all t shirts put away not 24 and have 4 left over. So we can just get another drawer and add it to the whole number.

So 5 drawers

Answer:

9 essay questions.

Step-by-step explanation:

We have been given that ada’s history teacher writes a test for the class with 26 questions. We can represent this information in an equation as:

x+y=26

We are also told that multiple choice worth 3 points each, so total number of points for x questions will be 3x.

As essays worth 8 points each, so total number of points for y questions will be 8y.

Since the test is worth 123 points, so we can represent this information in an equation as:

3x + 8y= 123

Now we will use substitution method to solve system of linear equations.

From equation (1) we will get,

x=26-y

Substituting this value in equation (2) we will get,

3×(26-y)+8y=123

78-3y+8y=123

78+5y=123

Let us subtract 78 from both sides of our equation.

78-78+5y=123-78

5y=45

Let us divide both sides of our equation by 5.

5y/5=45/5

y=9

To solve this problem, we need to use trigonometric ratio SOHCAHTOA.

Since we have opposite and hypothenuse value, we can use sine angle for this.

[tex]sin \theta = \frac{opposite}{hypothenuse}[/tex]

Let's substitute the values into the formula

[tex]sin45 = \frac{7}{c}\\ c = \frac{7}{sin 45} \\c = 7\sqrt{2}[/tex]

The value of x when y is 14.4 is 5.

It is given that

y ∝ 1/x

y = k/x....(1)

Where k is a constant of proportionality

The constant of proportionality is the ratio that relates two given values.

When y =6, x=12

Means, 6 = k/12

k = 72

Putting the value of k in equation (1)

y = 72/ x

14.4 = 72/ x

x = 5

Therefore, The value of x when y is 14.4 is 5.

Answer:

Acute

Step-by-step explanation:

Answer:

If you are finding out the lower angles they are acute but the top is right

Step-by-step explanation:

The area of a sector with a central angle of 2π/9 radians and a diameter of 20.6 mm is 37.01 mm²

It is given that

Central angle α= 2π/9

Diameter d= 20.6mm

So, radius r= 10.3mm

The area of a sector with central angle α and radius r is 0.5*r²*α

So, area of given sector = 0.5*10.3² * 2π/9

Area of given sector = 37.01 mm²

Therefore, the area of a sector with a central angle of 2π/9 radians and a diameter of 20.6 mm is 37.01 mm².

= 4x² + y² - 6xy + 3y² + 12x² + 8xy + 6x² + 8y² + 6xy

= 24x² + 12y² + 8xy

The accurate statements are:

A) About 25% of adults have cholesterol levels of at most 212.

D) One half of the cholesterol levels are between 180 and 211.

Q₃ (the third quartile) is 211, which is less than 212,

About 25% of adults have cholesterol levels of at most 212 is accurate.

Q₁ (the first quartile) is 100, which is greater than 180, About 75% of adults have cholesterol levels less than 180 is not accurate. We cannot determine that about 75% of adults have cholesterol levels less than 180 based on the given information.

The median divides the data into two equal halves, and it falls between Q₁ and Q₃.

So, one half of the cholesterol levels are between Q₁ and the median, but not specifically between 180 and 197.5.

One half of the cholesterol levels are between 180 and 211, as Q₁ is the lower boundary and Q₃ is the upper boundary of the interquartile range.

Measure of ∠WOV = 60°

Complementary angles

Step-by-step explanation:

       The box shows us that is equal to 90°. Angles ∠WOV and ∠WOX are complementary angles because we get 90° when we add them together. Since we are given the measure of ∠WOX we can subtract it from 90° to find the measure of ∠WOV.

90° - 30 ° = 60°

Using proportions, it is found that she should expect 4 of the next 12 appliances to be ovens.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, we have that out of 15 items, 5 are ovens. How many will be out of 12? To find out, we start with the rule of three.

15 items - 5 ovens

12 items - x ovens

Applying cross multiplication:

15x = 60

x = 4.
