Answer:

Each book cost 15 dollars.

Here’s the work: Sara had 136 dollars and spent some money on 8 books. After buying them she had 16 dollars left. So she spent 136 - 16 = 120 dollars on books. Since she bought 8 books with that money, each book cost her 120 / 8 = 15 dollars.

The total number of questions in the biology test are 40.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

For one biology test, Jhon correctly answered 14 questions. This gave him a score of 35%.

Let the total number of questions be w.

Now, 35% of w=14

35/100 ×w=14

35w=1400

w=1400/35

w=40

Therefore, the total number of questions in the biology test are 40.

Answer:

15 cm and 25 cm

Step-by-step explanation:

First let's mark the width with the letter b, and the length with a:

width: b

length: a = (2b - 5)

Then we have an inequality (P = 2a + 2b):

2 × (2b - 5) + 2b ≤ 80

4b - 10 + 2b ≤ 80

6b ≤ 80 + 10

6b ≤ 90 / : 6

b ≤ 15

a ≤ 2 × 15 - 5

a ≤ 25

Answer:15 cm and 25 cm

Step-by-step explanation:

Answer:

Answer:

15

Step-by-step explanation:

To start, we need to recognize that absolute value is a way of expressing the magnitude of a number, regardless of its sign. Thus, to get rid of the absolute value, we need to consider the two cases in which the expression can have either a positive or a negative sign.

For the case of a positive sign, we can simply write the expression as: 14-(x-6)

For the case of a negative sign, we can multiply both sides of the equation by -1 to get: -14 + (x-6)

Overall, we can express the expression without the absolute value symbol as:

14-(x-6) or -14 + (x-6)

Answer:

Caleb spent $91.96 for all of the items, including tax.

Step-by-step explanation:

First, let's calculate the cost of the shirts:

3 shirts * $12 per shirt = $36

Now, let's add the cost of the jacket and the shirts together:

$52 + $36 = $88

Next, let's calculate the amount of sales tax Caleb has to pay:

$88 * 4.5% = $3.96

Finally, let's add the sales tax to the total cost:

$88 + $3.96 = $91.96

Therefore, Caleb spent $91.96 for all of the items, including tax.

Step-by-step explanation:

[tex]\textsf{We are asked which expressions are equivalent to 10}^{\tt -6}.[/tex]

[tex]\textsf{We are given that we need to use the \underline{Negative Exponent Rule}.}[/tex]

[tex]\large\underline{\textsf{What is the Negative Exponent Rule?}}[/tex]

[tex]\textsf{We use the negative exponent rule to multiply the denominator of a number by}[/tex]

[tex]\textsf{itself how many times the value of the exponent is.}[/tex]

[tex]\underline{\textsf{Example of the Negative Exponent Rule;}}[/tex]

[tex]\tt 10^{-2}. \ \textsf{Start with 10}^{\tt 1}, \ \textsf{then continue.}[/tex]

[tex]\tt 10^{1} = \frac{10}{1} \rightarrow 10^{\tt 0} = \frac{10}{1 \times 10} = \frac{10}{10} \rightarrow 10^{\tt -1} = \frac{10}{10 \times 10} = \frac{10}{100} \rightarrow 10^{\tt -2} = \frac{10}{100 \times 10} = \boxed{ \frac{10}{1000} }[/tex]

[tex]\large\underline{\textsf{Use the Negative Exponent Rule for our given expressions;}}[/tex]

[tex]\tt \frac{1}{10 \times 10 \times 10 \times 10 \times 10 \times 10} \overset{\textsf{is the same as}} \rightarrow \frac{1}{10^{6}}[/tex]

-------------------------------------------------------------------------

[tex]\tt 10^{\tt -3} + 10^{\tt -3}[/tex]

[tex]\textsf{We should know that adding exponents is not like adding whole numbers/terms.}[/tex]

[tex]\textsf{We will need to evaluate 10}^{\tt -3} \ \textsf{using the Negative Exponent Rule.}[/tex]

[tex]\tt 10^{\tt 0} = \frac{10}{10} \rightarrow \tt 10^{\tt -1} = \frac{10}{10 \times 10} = \frac{10}{100} \rightarrow \tt 10^{\tt -2} = \frac{10}{100 \times 10} = \frac{10}{1000} \rightarrow \tt 10^{\tt -3} = \frac{10}{1000 \times 10} = \boxed{\frac{10}{10000}}[/tex]

[tex]\tt \frac{10}{10000} \ \textsf{can reduce to} \ \boxed{\tt \frac{1}{1000}}[/tex]

[tex]\underline{\textsf{We are now adding;}}[/tex]

[tex]\tt \frac{1}{1000} + \frac{1}{1000} = \frac{2}{1000} \rightarrow \boxed{\frac{1}{500} }[/tex]

[tex]\textsf{This does \underline{not} evaluate to 10}^{\tt -6}[/tex]

[tex]\large\boxed{\tt 10^{\tt -3} + 10^{\tt -3} \neq 10^{\tt -6}}[/tex]

-------------------------------------------------------------------------

[tex]\tt \frac{1}{10^{\tt 6}}[/tex]

[tex]\textsf{Because there's a fraction, the exponent is negative.}[/tex]

[tex]\large\boxed{\tt \frac{1}{10^{\tt 6}} = 10^{\tt -6}}[/tex]

hi

Step-by-step explanation:

i dont have an answer sorry but i just wanted to say im struggling w u (i'm doing delta mathhhh)

The point between the other two is point A

Arranging the given points in order, we get:

C (-7) < A (-4) < B (2)

We can conclude that, the point A is between points C and B.

Since A, B, and C are collinear, we have:

BA + AC = BC

Substituting the given values, we get:

5 + 4 = 9

9 = 9 --- true

We can conclude that, the point A is between points C and B.

Given that

A = -5

B = 7

We have

Midpoint C = (7 - 5)/2

Midpoint C = 1

Here, we have

Bisector BD

This means that

2x + 5 = 5x - 10

Evaluate

3x = 15

x = 5

So, we have

ABD = 2(5) + 5

ABD = 15

Then, we have

ABC = 2 * 15

ABC = 30

This means that the measure of angle ABC is 30 degrees
