Abebe's mom will give him ¼ of whatever he saves. If Abebe saves $23, his mom will give him 0.25 times $23, which is $5.75.

The question asks how much money Abebe's mom will give him if she gives ¼ of whatever he saves, and he saves $23. To find out how much his mom will give him, we must calculate ¼ of $23.

If Abebe saves $23, and his Mom will give him an extra $19.19 of whatever he saves, you can calculate the total amount he will have as follows:

Total amount = Savings + Mom's extra contribution

             = $23 + $19.19

             = $42.19

Therefore, Abebe will have a total of $42.19. None of the provided options ($5.26, $2.56, $5.11, $6.52) match this amount. It seems there might be an error in the answer choices or the problem statement. Please double-check the values or context provided.

Step 1: Convert the fraction ¼ to a decimal by dividing the numerator (1) by the denominator (4), which is 0.25.

Step 2: Multiply the decimal equivalent of ¼ (0.25) by the amount saved by Abebe ($23).

Step 3: Perform the calculation: 0.25 × $23 = $5.75.

Therefore, Abebe's mom will give him $5.75.

Final answer:

Abebe's mom will give him 19% of $23, which is calculated by multiplying 0.19 by $23, resulting in $4.37.

Explanation:

The subject of the question is Mathematics, specifically it deals with a percentage problem that involves finding what fraction of an amount will be added to it. To find out how much money Abebe's mom will give him based on the extra 19% of whatever he saves, we simply need to calculate 19% of $23. The calculation is as follows:

Convert the percentage to a decimal: 19% = 0.19.

Multiply this decimal by the amount saved: 0.19 × $23 = $4.37.

Therefore, Abebe's mom will give him an additional $4.37.

Final answer:

The astronomer calculates the diameter of the Sun using trigonometry and the given angle and distance, arriving at an approximate value of 1,727,804 miles which is a reasonable estimate when compared to the actual diameter of the Sun.

Explanation:

To calculate the diameter of the Sun, the astronomer uses the given angular size and the distance from the Earth to the Sun. Since we have the angle of 32 minutes (which is about 0.533° when converted to degrees), we can set up the following relationship using trigonometry:

diameter of the Sun = 2 × (distance to the Sun) × tan(½ × angular size in radians)

Let's convert the angular size from minutes to degrees and then to radians:

32 minutes = 32' / 60 = 0.533°

To convert degrees to radians, we use the fact that 180° is equivalent to π radians:

0.533° × (π radians / 180°) = 0.0093 radians

Now, we can use the distance to the Sun which is given as 92,919,800 miles and apply the formula:

diameter of the Sun = 2 × 92,919,800 miles × tan(0.0093 radians)

Performing the calculation:

diameter of the Sun ≈ 2 × 92,919,800 × 0.0093

diameter of the Sun ≈ 1,727,804 miles

This is an approximation because the angular size varies slightly due to the elliptical orbit of Earth. Comparing to the actual diameter of the Sun, which is about 1.39 million kilometers (or about 864,000 miles), we can see that our calculated value is a reasonable estimate, keeping in mind that trigonometric calculations rely on a circular orbit assumption and ideal conditions.

First of all, we will find quantity of sugar needed to make one cake as:

[tex]\text{Sugar needed to make one cake}=\frac{33.2\text{ gm}}{4}[/tex]

[tex]\text{Sugar needed to make one cake}=8.3\text{ gm}[/tex]

To find quantity of sugar needed to make 6 cakes, we will multiply 6 by 8.3 grams.

[tex]\text{Sugar needed to make 6 cakes}=6\times 8.3\text{ gm}[/tex]

[tex]\text{Sugar needed to make 6 cakes}=49.8\text{ gm}[/tex]

The statement (x – y)z = xz – yz is always true due to the distributive property in mathematics. Moreover, an algebraic expression in the simplest form does have like terms. Like terms are grouped together to simplify the expression.

For every real number x, y, and z, the statement (x – y)z = xz – yz is always true. This is an illustration of the distributive property in mathematics, which states that for all real numbers, the equation a(b + c) = ab + ac holds true. In the given equation, the place of 'a' is taken by 'z', while 'x' and 'y' replace 'b' and 'c' respectively.

On the other hand, an algebraic expression in simplest form does have like terms. Like terms are terms with the same variable part. For instance, in the expression 3x2 + 2x - x2 + 4 +5x - 2, the like terms can be combined to simplify the expression to 2x2 + 7x + 2.

Final answer:

By calculating 5/7 of 27, we find that approximately 19 students are wearing jeans today after rounding down to the nearest whole number.

Explanation:

To find out how many students are wearing jeans, we need to calculate 5/7 of the 27 students in the class.

First, we determine the value of one seventh of the class by dividing the total number of students by 7:

27 ÷ 7 = 3.8571 (we can round this to 3.86 for simplicity)

Next, we multiply this result by 5 to find five sevenths:

3.86 × 5 = 19.3

Since we cannot have a fraction of a student, we round down to the nearest whole number. Therefore, approximately 19 students are wearing jeans today.

It's important to understand and apply fractions and division to solve such mathematical problems. This example showcases the practical application of these concepts.

Answer:

Mia hiked 450 ft before the first stop.

Step-by-step explanation:

Mia hiked along a 2250 foot mountain trail.

She stopped 4 times, she rested and after that stopped 5 times.

She walked the same distance between each stop.

It means 5 stops and the same distance with each time.

We need to calculate the distance between each stop. Total distance T = 2250 ft, and stops S = 5.

We can isolate the distance of each Stop E from:

T = S*E

E = T/S = (2250 ft)/(5)

E = 450 ft.

Finally, She hiked 450 ft before the first stop. 

Mia hiked 450 feet before the first stop.

Distance is defined as the product of speed and time.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

Given that Mia hiked along a 2250-foot mountain trail.

She stopped 4 times along the way to rest and then a fifth time at the end of the trail,

And she walked the same distance between each stop.

It indicates 5 stops with a constant distance between them.

To determine the distance between each stop.

Total distance D = 2250 ft, and stops X = 5.

Each Stop Y's separation from the other can be determined.:

⇒ D = X×Y

⇒ Y = D/X

Substitute the value of D and X in the above equation,

⇒ Y = (2250 feet)/5

Divided by 5

⇒ Y = 450 feet.

Hence, Mia hiked 450 feet before the first stop.

Step-by-step explanation:

The average rate of change in the number of bacteria between Hour 2 and Hour 5 is approximately -3,482 bacteria/hour.

To find the average rate of change in the number of bacteria between Hour 2 and Hour 5, we need to calculate the difference in the number of bacteria at Hour 5 and Hour 2, and then divide it by the difference in time (3 hours).

At Hour 2, substitute x = 2 into the function f(x) = 40,000(0.75)^x:

f(2) = 40,000(0.75)^2 = 40,000(0.5625) = 22,500 bacteria.

At Hour 5, substitute x = 5 into the function:

f(5) = 40,000(0.75)^5 = 40,000(0.3164) = 12,656 bacteria.

Now we can calculate the average rate of change:

Average rate of change = (f(5) - f(2)) / (5 - 2) = (12,656 - 22,500) / 3 = -3,482 bacteria/hour. The average rate of change in the number of bacteria between Hour 2 and Hour 5 is approximately -3,482 bacteria/hour.
