Explanation:

Two points will always be collinear, but the same can't be said for three, since in some occasions one point is outside the line.

There are 3 dots in each row of Fritz's array. This conclusion is reached by dividing the total number of dots (15) by the number of rows (5). This is an exercise in simple division and understanding arrays in mathematics.

The subject of this question from Fritz is Mathematics, specifically, it's about arrays and simple division.

To find out how many dots are in each row of Fritz's array, we need to use division. In this case, the total number of dots (15) would be divided by the number of rows (5).

So, we calculate: 15 ÷ 5 = 3.

So, there are 3 dots in each row of Fritz's array. We know this is correct because the definition of an array in mathematics is a collection of objects or numbers arranged in rows, and each row has the same number of items.

Answer:

f(x) is greater

Step-by-step explanation:

The function that has a greater value when x = 3 is: A. f(x) is greater.

In Mathematics and Geometry, a linear function refers to a type of function whose equation is graphically represented by a straight line on the xy-plane or cartesian coordinate.

Based on the information provided, we can logically deduce the following linear functions;

f(x) = 3x + 1

g(x) = 4x - 5

When x is equal to 3, we have:

f(x) = 3x + 1

f(3) = 3(3) + 1

f(3) = 10

g(x) = 4x - 5

g(3) = 4(3) - 5

g(3) = 7.

Therefore, f(x) is greater.

Answer:

Each bus could pick up 49 students

Step-by-step explanation:

(449-8):9=49

Answer:

Number of students on each bus = 49

Step-by-step explanation:

On Monday, 449 students went on a trip to the zoo. All 9 buses were filled and 8 students had to travel in cars.

Total number of students = 449.

Number of students traveled in car = 8

Number of students traveled in bus = 449 - Number of students traveled in car = 8

Number of students traveled in bus = 449 - 8 = 441

Number of buses = 9

Number of students traveled in bus = Number of buses x number of students on each bus

441 = 9 x number of students on each bus

Number of students on each bus = 49

Final answer:

The number that is between 21 and 3π/2 is 5.

Explanation:

To find the number that is between 21 and 3π/2, we need to determine the value of 3π/2 first. Since π is approximately 3.14, 3π/2 is approximately (3)(3.14)/2 = 4.71.

Now we can compare this value to 21. Since 4.71 is less than 21, we need to find a number that is greater than 4.71 but less than 21. The only option in the given choices that fits this criteria is Option C, 5.

Answer:

t = [tex]\frac{6}{7}[/tex]

Step-by-step explanation:

Given that t varies inversely as the square root of u then the equation relating them is

t = [tex]\frac{k}{\sqrt{u} }[/tex] ← k is the constant of variation

To find k use the condition t = 3 when u = 4, thus

k = t[tex]\sqrt{u}[/tex] = 3 × [tex]\sqrt{4}[/tex] = 3 × 2 = 6

t = [tex]\frac{6}{\sqrt{u} }[/tex] ← equation of variation

When u = 49, then

t = [tex]\frac{6}{\sqrt{49} }[/tex] = [tex]\frac{6}{7}[/tex]

The value of 't' when 'u = 49' in the equation [tex]'t = k/\sqrt(u)[/tex]' is approximately '0.86'. This was calculated using the concept of inverse variation in mathematics.

The question is dealing with the concept of inverse variations in math. The given expression states that 't' varies inversely with the square root of 'u'. This can be represented mathematically as  [tex]'t = k/\sqrt(u)',[/tex] where 'k' is the constant of variation.

From the problem we know that 't = 3' when 'u = 4'. Substituting these terms in into the equation above, we can solve for 'k'. Doing this yields  [tex]'k = 3\times \sqrt(4) = 6.'[/tex]

Now that we have found 'k', we can find the value of 't' when 'u = 49'. We can do this by plugging in the known values into the equation. So [tex]'t = 6/\sqrt(49)'.[/tex] It simplifies to 't = 6/7' or about '0.86'.

Answer:

Option C (The expression 2.35c + 1.75m represents the money earned from selling c bags of cookies and m bags of muffins).

Step-by-step explanation:

It is given that a bag of cookies is priced at $2.35 and a bag of muffin is priced at $1.75. It is also given that the student sells c bags of cookies and m bags of muffins. The total revenue earned by the student by selling c bag of cookies = $2.35 * c bags = $2.35c and the total revenue earned by the student by selling m bag of muffins = $1.75 * m bags = $1.75m. Therefore, the total revenue earned by the student by selling both cookies and muffins = 2.35c + 1.75m. This expression (2.35c + 1.75m) represents the money earned from selling c bags of cookies and m bags of muffins. Therefore, C is the correct choice!!!

Step-by-step explanation:I used a calculator

Answer:

Step-by-step explanation: 36,211,762

To find the total height of the building, we need to calculate the sum of the heights of all the floors.

Height of the ground floor = 24 feet

Height of each floor (except ground floor) = 17 feet

Number of floors (excluding ground floor) = 7 - 1 = 6

Total height of the building = Height of the ground floor + (Height of each floor * Number of floors)

Total height of the building = 24 + (17 * 6)

Total height of the building = 24 + 102

Total height of the building = 126 feet

Therefore, the building is 126 feet tall.

3/4 is greater than 7/10.

Find the least common denominator or LCM of the two denominators:

LCM of 4 and 10 is 20

For the 1st fraction, since 4 × 5 = 20,

3 /4=  

3 × 5

4 × 5  =  

15 /20

Likewise, for the 2nd fraction, since 10 × 2 = 20,

7 /10  =  

7 × 2

10 × 2  =  

14 /20

Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

15 /20  >  14 /20  or  3 /4  >  7 /10

Answer:

3/4 is larger

Step-by-step explanation:

The common denominator is 40

multiply

30/40 and 28/40

30/40 is larger, simplify 3/4 is bigger than 7/10

Final answer:

Manuel spent 90% of his total grocery expenses on fruit. To calculate this, the amount spent on fruit ($36) is divided by the total spent ($40), and then multiplied by 100%.

Explanation:

Manuel spent a total of $40 at the grocery store and out of that, $36 was spent on fruit. To find out the percentage that he spent on fruit, you can use the formula:

Percentage = (Amount spent on fruit / Total amount spent) x 100%

Plugging in the values gives us:

Percentage = ($36 / $40) x 100% = 0.9 x 100% = 90%.

Thus, Manuel spent 90% of his total grocery expenses on fruit.

Answer:

The estimate of the product is about 35 answer C

Step-by-step explanation:

- We use rounding to estimate the product of two fractions

- The mixed number has whole number and fraction

- To round the mixed number we look to the fraction

- If the numerator is half or greater than half the denominator, then we

  add the whole number by 1 and cancel the fraction

- If the numerator is less than half the denominator, then we keep the

  whole number as it and cancel the fraction

- Ex: If the mixed number is [tex]2\frac{3}{4}[/tex], 3 is more than

 half 4 then we will add 2 by 1 and cancel the fraction part, the

 mixed number [tex]2\frac{3}{4}[/tex] after rounding is 3

- Ex: If the mixed number is [tex]5\frac{1}{4}[/tex], 1 is less than

 half 4 then we will keep 5 as it and cancel the fraction part, the

 mixed number [tex]5\frac{1}{4}[/tex] after rounding is 5

* Lets solve the problem

∵ In the part [tex]4\frac{3}{4}[/tex] 3 is more than half 4

∴ The rounding value of [tex]4\frac{3}{4}[/tex] is 5

∵ In the part [tex]7\frac{2}{17}[/tex] 2 is less than half 17

∴ The rounding value of [tex]7\frac{2}{17}[/tex] is 7

∴ [tex]4\frac{3}{4}*7\frac{2}{17}=5*7=35[/tex]

* The estimate of the product is about 35

When multiple of the same number are multiplied together, this can be represented as an exponent. An exponent is a way to write repeated multiplication of a number by itself. In your case, 7 multiplied by itself 3 times (7*7*7) can be written using exponents as 7^3.

In mathematics, when you multiply the same number multiple times, you can express that multiplication as an exponent. An exponent tells you how many times to multiply the number, or the base, by itself. For example, in your question, the number 7 is multiplied by itself 3 times (7*7*7), so this multiplication can also be written with exponents. The correct way to express this multiplication using exponents is 73.

But one thing i realized when i was doing division by fractions is that if you flip the fraction then you can multiply and you get the same exact answer. SO lets try: 5/3 = 1.6666

1.6666*5=8.3333333

So you can use that trick when dividing a whole number by fractions. It makes it a lot easier.
