Answer: x=5

Step-by-step explanation:

21+x=26 (you need to isolate x)

-21    -21 (inverse operation to isolate x)

(subtract 21 from 26)

x=5

Answer: x = 5

Step-by-step explanation: In this problem, we want to get x by itself on one side of the equation. Since we have 21 + x, in order to get x by itself, we must subtract 21 from the left side of the equation and when we subtract 21 from the left side of the equation, we must also subtract 21 from the right side of the equation in order to keep our equation balanced.

So on the left, +25 and -25 cancel eachother out and on the right, 26 - 21 simplifies to 5 so x = 5. To check our answer, we plug 5 back in for x in the original equation and we get 21 + (5) = 26 or 26 = 26 which is a true statement  so we know our answer is correct.

Answer:

10cm

Step-by-step explanation:

find the diameter of the circumference of 5cm:

d= c÷3.14

=5cm÷3.14

=1.6cm

Double 1.6cm:

1.6×2= 3.2

Find the new cicumference:

c= 3.14×d

= 3.14×3.2

= 10cm

Answer:

Step-by-step explanation:

Alright, lets get started.

QM is the diameter given.

NL is the tangent given.

The tangent makes 90 degree angle with diameter.

hence the angle QML will be : 90°   ...............   Answer

Similarly, QMN will also be 90°

The angle PMQ is given as 27°

Hence the angle PMN will be = [tex]90-27[/tex]

The volume of white color used by Maria is 20 liter

Solution:

Maria, a color specialist, mixes 2 parts of white and 13 parts of red to develop a particular shade

She creates 150 liters of the shade

Given ratio is:

2 parts of white and 13 parts of red

white : red = 2 : 13

Let the white mixed be 2x

Let the red mixed be 13x

Total shade = 150 liters

Therefore,

2x + 13x = 150

15x = 150

x = 10

Therefore, volume of white color used = 2x = 2(10) = 20

Thus, volume of white color used by Maria is 20 liter

Answer:

$0.85 per tomato

Step-by-step explanation:

A unit rate is the cost for one item. Like $0.99 for this one bag of skittles.

So $3.40 divided by four is $0.85.

The unit rate would be 0.85. If you divide 3.40 by 4 you 0.85

Answer:

If one ounce of toppings cost $0.50, then you would need to take $0.50*11

.5*11= 5.5

11 ounces would be $5.50

Answer:Any number

Step-by-step explanation:

Among the options given, 2/11 is most similar to 0.18 when we convert these fractions to their decimal format. Remember that this is an approximation since 2/11 results in a repeating decimal.

The given expression is equivalent to 0.18. To find out which among the provided options this is equivalent to, we need to convert these fractions to decimal format. Let's start with A.
A. 1/9 is equal 0.111 repeating.
B. 2/11 equals approximately 0.1818 repeating.
C. 1/11 equals approximately 0.0909 repeating.
D. 11/2 equals 5.5.

Comparing these to our given expression of 0.18, we find that Option B (2/11) is most closely equivalent after rounding. It's worth noting the repeating decimal in 2/11, which is why it is an approximation rather than an exact equivalent.

Answer:

(h+8)+5

Step-by-step explanation:

First, you need to add 8 to h, which is h+8 and then you need to add 5 to the result, which means you need to put parentheses around h+8 because you need to do that first. then your answer becomes (h+8)+5.

After adding 8 to h and then 5 to the result, the final value will be h + 13.

To perform the specified operations, you first need to add 8 to the value of h and then add 5 to the result. This can be expressed as a mathematical expression:

Result = (h + 8) + 5

Start with the value of h.

Add 8 to it, which gives you (h + 8).

Now, take the result from step 2 and add 5 to it, yielding the final result.

This process essentially means you're increasing the original value of h by 8, and then further increasing the updated value by 5. The final result will be h + 8 + 5, or simply h + 13.

So, the answer is that you will end up with a value equal to h + 13 after performing these operations.

Angles of triangle are 40°,60° and 80°.

Step-by-step explanation:

Given:

if angles of a triangle are 2 is to 3 is to 4.

Let the common factor between the angles be 'x'.

So we can say that;

Angle 1 = [tex]2x[/tex]

Angle 2 = [tex]3x[/tex]

Angle 3 = [tex]4x[/tex]

We need to find the value of each angle.

Solution:

Now we know that;

"Sum of all angles of triangle is 180°."

framing in equation form we get;

[tex]Angle \ 1+Angle\ 2+Angle \ 3 =180[/tex]

Substituting the values we get;

[tex]2x+3x+4x=180\\\\9x=180[/tex]

Dividing both side by 9 we get;

[tex]\frac{9x}{9}=\frac{180}{9}\\\\x=20[/tex]

Angle 1 = [tex]2x=2\times20=40\°[/tex].

Angle 2 = [tex]3x=3\times20=60\°[/tex]

Angle 3 = [tex]4x=4\times20=80\°[/tex]

Hence Angles of triangle are 40°,60° and 80°.

The drama club receives $7 for each ticket that they sell.

Step-by-step explanation:

Given,

Amount received by school = x dollars

Amount received by school for 96 tickets = 96x

Amount received by drama club = remaining amount after school

Total amount of 96 tickets = 96x+672

Here,

96x is the share of school

672 is the share of drama club for 96 tickets.

Therefore;

96 tickets = dollars

1 ticket = [tex]\frac{672}{96}[/tex]

1 ticket = 7 dollars

Option A

The simple interest earned over 6 years is $ 4050

Solution:

Martha invested a principal amount of $15,000 into a savings account that earns simple interest at a rate of 4.5% per year

The formula for simple interest is given as:

[tex]Simple\ Interest = \frac{p \times n \times r}{100}[/tex]

Where, "p" is the principal and "n" is the number of years and "r" is the rate of interest

From given,

p = 15000

r = 4.5 %

n = 6 years

Substituting the values we get,

[tex]Simple\ Interest = \frac{15000 \times 4.5 \times 6}{100}\\\\Simple\ Interest = 150 \times 4.5 \times 6\\\\Simple\ Interest = 4050[/tex]

Thus simple interest earned over 6 years is $ 4050

Final answer:

Martha will earn $4,050 in simple interest over 6 years on her $15,000 savings account at a 4.5% annual rate. This is calculated using the simple interest formula, Interest = Principal × Rate × Time.

Explanation:

To calculate the simple interest that Martha will earn over a period of 6 years, we will use the formula for simple interest: Interest = Principal × Rate × Time. Here, the principal amount is $15,000, the annual interest rate is 4.5% (which is 0.045 in decimal form), and the time is 6 years.

Let's plug these values into the formula:

Interest = $15,000 × 0.045 × 6

Interest = $15,000 × 0.27

Interest = $4,050

Therefore, the total amount of interest Martha will earn over 6 years is $4,050, which matches option A.

Each piece is 20 inches long.

Step-by-step explanation:

The length pieces of the ribbon can be obtained by dividing the total length of ribbon by total number of pieces

Given

String length = 168 inches

Number of pieces = 6

So the length of each piece will be:

[tex]Length\ of\ each\ piece = \frac{Length\ of\ string}{Number\ of\ pieces}\\= \frac{168}{6}\\= 28\ inches[/tex]

Cutting 8 inches from each piece means that the length will be reduced 8 inches

[tex]Length\ after\ cutting\ 8\ inches = \ length\ of\ each\ piece - 8\\= 28-8\\=20\ inches[/tex]

Hence,

Each piece is 20 inches long.

The pressure [tex]64kg/cm^{2}[/tex] has to be applied to have a volume of [tex]200cm^{3}[/tex]

Explanation:

According to Boyle's law, for a fixed amount of gas, the volume and pressure are inversely proportional.

[tex]P_{1} \cdot V_{1}=P_{2} \cdot V_{2}[/tex]

Substituting the values, we get,

[tex]40 \times 320=P_{2} \times 200[/tex]

Dividing both sides by 200,

[tex]\frac{40 \times 320}{200}=P_{2}[/tex]

Simplifying the terms, we get,

[tex]\begin{aligned}\frac{12800}{200} &=P_{2} \\64 &=P_{2}\end{aligned}[/tex]

Thus, the pressure [tex]64kg/cm^{2}[/tex] has to be applied to have a volume of [tex]200cm^{3}[/tex]
