The statement for which the inverse is false is A, because if one angle of a triangle equals 60°, the triangle is not necessarily equilateral.
The question asks for which statement the inverse is false. To answer this, we analyze each statement and its inverse:
A. If a triangle is an equilateral triangle, then one angle equals 60°. Inverse: If one angle of a triangle equals 60°, then the triangle is equilateral. This could be false if the triangle is not equilateral but one angle happens to be 60°.
B. If a triangle is a right triangle, then the other two angles add up to 90°. Inverse: If two angles of a triangle add up to 90°, then it is a right triangle. This is true, given the geometric principle that the sum of angles in a triangle is 180°.
C. If a triangle is an equilateral triangle, then each of the angles equals 60°. Inverse: If each angle of a triangle equals 60°, then it is an equilateral triangle. This is true, as by definition, an equilateral triangle has all angles equal.
D. If a triangle is a right triangle, then one angle equals 90°. Inverse: If one angle of a triangle equals 90°, then it is a right triangle. This is true, as by definition, a right triangle has one 90° angle.
Therefore, the statement for which the inverse could be false is A.

What is the value of x?
Step-by-step explanation:
It is a heptagon
sum of internal angle = 900
X + 120 + 158 + 126 + 125 +121 + 139 = 900
X + 789 = 900
X = 900 -789
X = 111 degree
What is the value of 22x + 3 when x = 5? How much money is 22 nickels and 3 pennies?
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.
What is the answer to this question
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

Shelly spent 10 minutes jogging and 20 minutes cycling and burned 300 calories. The next day, Shelly swapped times and did 20 minutes of jogging and 10 minutes of cycling, burning the same number of calories. How many calories were burned for each minute of jogging and how many for each minute of cycling?
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]

If you have the following equation; 4x - 4.5 = 10.73x + 5.7 + 7x, what would you multiply each term by to get rid of the decimals in the equations?
Answer:
100
Step-by-step explanation:
You are given the equation
[tex]4x-4.5=10.73+5.7+7x[/tex]
There are 5 coefficients:
[tex]4, \ -4.5,\ 10.73,\ 5.7,\ 7[/tex]
Two of them are integers
[tex]4,\ 7[/tex]
two of them are decimals with one digit after point
[tex]-4.5,\ 5.7[/tex]
and one is a decimal with two digits after point
[tex]10.73[/tex]
To get rid of fractions, we have to get rid of digits after point. The maximum number of digits after point is 2, then we have to multiply the equation by 100:
[tex]400x-450=1,073x+570+700x[/tex]
Final answer:
To eliminate decimals in an equation, multiply all terms by a power of 10 to shift the decimals to whole numbers, simplifying the calculation process.
Explanation:
To get rid of decimals in the equation 4x - 4.5 = 10.73x + 5.7 + 7x, you would multiply each term by a power of 10 that shifts the decimals to whole numbers. By determining the highest number of decimal places in the terms, you can multiply all terms by a suitable power of 10.
For example, if the highest number of decimal places is 2, you would multiply all terms by 100. This action shifts the decimals two places to the right, converting them into whole numbers and simplifying the equation.
By multiplying all terms by the appropriate power of 10, you eliminate decimals and work with whole numbers, making it easier to solve the equation.

WHAT DOES 12F+24 REPRESENT
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.

the bakers at Healthy bakery can make 170 bagels in 5 hours. how many bagels can they bake in 13 hours? what was the rate per hour
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.
One painting shows 520 different types of ladybugs.
Another painting shows 750 different types. How many
times as great is the value of the digit 5 in 520 than the
value of the digit 5 in 750? How do you know?
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.
Explanation: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.

Write a possible exponential function in y=ab^x form for the graph described below.
-> Has a y-intercept of (0,3) and passes through the point (2,48)
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'.
Explanation: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.

Both sides of an equation have quadratic
expressions. The graph of one quadratic opens
upward. The graph of the other opens downward.
What are the possible number of intersections for
this system?
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.
let;
First quadratic equation whose graph open upward is
[tex]ax^{2} + bx + c = 0[/tex] , where (a≠0)
when a>0 is positive the graph upward .
And second quadratic equation whose graph open downwards is
[tex]-ax^{2} + bx + c = 0[/tex] , where ( a≠0 )
When a<0 is negative the graph open downwards.
There are 3 possibilities for the graph as shown in the figure.
Having zero intersection where the graph aren't touching.
Having one intersection point where the graph touching at one point.
Having two intersection points where the graph overlap.
So, the greatest possible number of intersections for these graphs is 2 as shown in figure.
