Answer:

10 times greater

Step-by-step explanation:

the 5 in 520 is in the  hundreds place value

The 5 in 50 is in the tens place value

50 *10 = 500

From units to tens-------------Multiply by 10 (2*10=20)

From tens to  hundreds-------Multiply by 10  (20*10=200)

From hundreds to thousands----Multiply by 10 (200*10=2,000)

And so on

The value of 5 in 520 is in the hundreds place, so it equates to 500. Conversely, the 5 in 750 is in the tens place, meaning it equals 50. Thus, the 5 in 520 is 10 times greater than the 5 in 750.

This question pertains to the place value in numbers, an essential mathematical concept. In the number 520, the digit 5 is in the hundreds place, which means its value is 5*100 = 500. On the contrary, in the number 750, the digit 5 is in the tens place, hence, it's value is 5*10=50.

Therefore, to find out how many times the value of the 5 in 520 is greater than the value of the 5 in 750, divide the value of the 5 in 520 (which is 500) by the value of the 5 in 750 (which is 50). So, 500 divided by 50 equals 10. This reveals that the value of the digit 5 in 520 is 10 times greater than the value of the digit 5 in 750.

Answer:

12(f + 2)

Step-by-step explanation:

12F + 24 = 12 (f + 2)

Answer:

It is an algebraic expression that has an answer which can be determined by multiplying a known value of variable F by 2, and adding 24 to the outcome.

Step-by-step explanation:

2F + 24 is an algebraic expression which implies that if a variable F is multiplied by 2 and 24 is added to it, there would be a certain outcome. This expression has no answer unless the value of F is known.

By factorisation, the expression can be re-written as:

                  2F + 24 =  2 (F + 12)

which would give the same answer as the initial expression.

Therefore, the given algebraic expression represents a value which can be determined by multiplying a known value of variable F by 2, and adding 24 to the outcome.

Answer:

113

$1.13

Step-by-step explanation:

22x + 3 when x = 5 is written 22(5) + 3

You multiply first, 22(5) = 110 + 3 = 113

a nickel is worth .05 so you mulitply .05 x 22 which gets you 1.1 and 3 pennies is .03 and when you add the two together you get $1.13

Answer: The value of 22x+3 is 113. The amount of money that equals 22 nickels and 3 pennies. That answer is also 1113.

Step-by-step explanation:

For the first problem u want to basically do 22 times 5 and that gives you 110. Then after doing that u want to do 110+3 which equals 113.

For the second one since nickels equal 5 cents u want to do 22•5 which gives you 110 and then you do 110+3 and that gives you 113.

Answer:

442

Step-by-step explanation:

170/5 (to find per hour)

34*13 = 442

Answer:

The rate per hour is 34 bagels per hour. They can bake 442 bagels in 13 hours.

Step-by-step explanation:

Rate per hour:

170/5= 34

You do this because you want to find the amount of bagels they can bake in 1 hour, which is found through 170/5.

Bagels in 13 hours:

34*13= 442

You use the unit rate established, 34 bagels per hour, and multiply it by 13 hours, 13*34.

Answer:

- 1, 1, - 3

Step-by-step explanation:

To obtain the value of f(1), we require the corresponding value of y from the graph when x = 1

From the graph

when x = 1 the value of y on the graph is - 1 ⇒ f(1) = - 1

Similarly

f(3) means what is the value of y corresponding to x = 3

From the graph when x = 3 then y = 1 ⇒ f(3) = 1

and f(- 1) = - 3

(x−5)(x2−2x−6)

mutiply the brackets together

(x)(x^2)=x^3

(x)(-2x)=-2x^2

(x)(-6)=-6x

(-5)(x^2)=-5x^2

(-5)(-2x)=10x

(-5)(-6)=30

x^3-2x^2-6x-5x^2+10x+30

x^3-2x^2-5x^2-6x+10x+30 ( combine like terms)

Answer:

slope = - [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3x + 4y = 12 into this form

Subtract 3x from both sides

4y = - 3x + 12 ( divide all terms by 4 )

y = - [tex]\frac{3}{4}[/tex] x + 3 ← in slope- intercept form

with slope m = - [tex]\frac{3}{4}[/tex]

This all u need my dud

Alicia make 3 blankets with the fabric she bought.

Given, Alicia bought 5.75 yards of fleece fabric.

For one blanket She needs 1.85 yards of fabric.

We have to calculate the no. of blankets.

So, the no of blankets will be,

[tex]N=\frac{total \ yards}{yard\ needed \ 1 \ blanket}[/tex]

[tex]N=\dfrac{5.75}{1.85} \\\\N=3.10810[/tex]

Since the number of blanket must be a whole number so number of blanket here is 3.

Hence Alicia make 3 blankets with the fabric she bought.

Answer:

Step-by-step explanation:

Any [tex]b\neq 0[/tex] raised to the 0-th power will give 1. So [tex]a=3[/tex]

Once you know that, from the passing through (2,48) you get:

[tex] 48=3b^2\\ 16=b^2 b=4 [/tex]

Notice that,even if -4 satisfies the condition, exponential functions are defined only and only if the base is positive and not equal to 1. (if the base was 1, you'd get an horizontal line, and with a negative base the function starts losing meaning in the real plane in a series of points.

To write the exponential function in y = ab^x form, we use the given y-intercept and a point on the graph to find the values of 'a' and 'b'.

To write the exponential function in y = ab^x form, we need to find the values of a and b.
Based on the information given, we know that the y-intercept is (0,3), which means that when x = 0, y = 3.
So, we have the equation 3 = ab^0, which simplifies to a = 3. Now, using the point (2,48), we can substitute the values of a and x to find the value of b. We get 48 = 3b^2, which simplifies to 16 = b^2. Taking the square root, we find that b = 4. Therefore, the exponential function is y = 3 * 4^x.

Step-by-step explanation:

Answer:

See explanation

Step-by-step explanation:

Devin brought his snail collection to school. He has 10 snails.

the smallest number of snails in the tank is 0 and the greatest number of snails in the tank is 10. Also the number of snails in each tank must be a whole number (Devin cannot put half of the snail into the tank). There are 11 whole numbers between 0 and 10.

Hence,  all 11 possibilities to divide snails into two tanks are:

[tex]\begin{array}{cc}\text{Tank 1}&\text{Tank 2}\\ \\0&10\\1&9\\2&8\\3&7\\4&6\\5&5\\6&4\\7&3\\8&2\\9&1\\10&0\end{array}[/tex]

The sums of two numbers in each row must be exactly 10 as the total number of snails Devin has.

Answer:

10 calories were burned for each minute of jogging  and  10 calories were burned for each minute of cycling.

Step-by-step explanation:

Let be "j" the amount of calories Shelly burned for each minute of jogging and "c" the amount of calories Shelly burned for each minute of cycling.

Set up a system of equations:

[tex]\left \{ {{10j+20c=300} \atop {20j+10c=300}} \right.[/tex]

You can apply the Elimination method: multiply the first equation by -2, then add the equations and  solve for "c":

[tex]\left \{ {{-20j-40c=-600} \atop {20j+10c=300}} \right.\\...............................\\-30c-300\\\\c=10[/tex]

Now, substitute the value of "c" into any original equation and solve for "j":

[tex]10j+20(10)=300\\\\10j=300-200\\\\10j=100\\\\j=10[/tex]

One line has a positive slope and the other a negative slope, they are bound to intercept eventually, so that's why there can't be zero solutions. Two lines can't intercept each other twice, and if they have opposite slopes they can't have infinite solutions.

First quadratic equation whose graph open upward is
