2. Aashvi is making garlic naan. The recipe calls for 2 cups of flour, but Aashvi only has teaspoons. If 24 teaspoons are equal to 1/2 cup, how many teaspoons will Aashvi use to measure 2 cups of flour? *
Answer:
98 teaspoons
Step-by-step explanation:
Aashvi is making garlic naan. The recipe calls for 2 cups of flour, but Aashvi only has teaspoons. If 24 teaspoons are equal to 1/2 cup, how many teaspoons will Aashvi use to measure 2 cups of flour? *
From the above question, we understand that:
1/2 cup of flour = 24 teaspoons
2 cups of flour = x teaspoons
Cross Multiply
1/2x = 24 × 2
x = 48 ÷ 1/2
x = 48 × 2
x = 98 tea spoons
Therefore, Aashvi will use 98 teaspoons to measure 2 cups of flour.

What is the solution to the system of equations?
The solution to the system of equations is A. (-2, 2)
How to calculate the value?The system of equation was:
2x + 3y = 2 ..... i
y = 1/2x + 3 ...... ii
Substitute equation ii into i
2x + 3/2x + 9 = 2
Multiply through by 2.
7x + 18 = 4
7x = -14
Divide
x = 14/7
x = -2
Also, y = 1/2x + 3
y = 1/2(-2) + 3
y = -1 + 3
y = 2
Therefore, the solution to the system of equations is (-2, 2).

Function g(x) has a removable discontinuity at x = c, where g(c) is undefined. Which statement describes the one-sided limits at x = c?
Answer:
B
Step-by-step explanation:
The function that describes the one-sided limits at x = c.
[tex]\lim_{x \to c^-} g(x) = a\\\\ \lim_{x \to c^-} g(x) = a[/tex] ( for some value of a).
What is removable discontinuity?A discontinuity is removable if the limit of the function at the point of discontinuity exists and the value of the function exists but they aren't equal to each other.
We can remove that discontinuity by making the value of the function equate to the limiting value of the function at that point.
Function g(x) has a removable discontinuity at x = c,
where g(c) is undefined.
In this case, the statement that's is true for g(x) is that you can remove the discontinuity at x = c by defining g(c) = a.
The function that describes the one-sided limits at x = c.
[tex]\lim_{x \to c^-} g(x) = a\\\\ \lim_{x \to c^-} g(x) = a[/tex] ( for some value of a).

Solve for x in the triangle above
Answer:
x = 30
Step-by-step explanation:
The interior angles of a triangle must always add up to 180.
2x + 2x + 3x - 30 = 180
Add 30 to both sides to seperate variables.
2x + 2x + 3x = 210
Combine like terms.
7x = 210
Divide by 7 to isolate x.
x = 30

Your friend made $324 babysitting last year.This year she made 296% of what she made last year.How much more did your friend make this year?
Answer:
$635
Step-by-step explanation:
She made a total of $959 anad last year she made $324 so you then subtract the ammounts because the problem wants to know how much MORE she made.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
The more amount made this year is $635.04
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Your friend made $324 babysitting last year.
This year she made 296% of what she made last year.
This means,
The amount this year.
= 296/100 x 324
= $959.04
The difference in the amount.
= $959.04 - $324
= $635.04
The difference in the amount can also be calculated as,
= 296% - 100%
= 196% more this year.
So,
196% of $324
= 196/100 x 324
= $635.04
Thus,
The more amount made this year is $635.04

9514 1404 393
Answer:
(13.06, 16.41)
Step-by-step explanation:
Any point not on a perpendicular bisector of the line between towns will be closer to one town than the other. So, the intersection of perpendicular bisectors will be the equidistant from all towns. That point is the circumcenter of the circle circumscribing the triangle with the towns as its vertices. This can be found as the intersection of two perpendicular bisectors of the segments between the towns.
The midpoint of AB is ...
(A +B)/2 = ((15, 3) +(25, 10))/2 = (40, 13)/2 = (20, 6.5)
The midpoint of AC is ...
(A +C)/2 = ((15, 3) +(0, 20))/2 = (15, 23)/2 = (7.5, 11.5)
__
The differences between points are ...
B -A = (25, 10) -(15, 3) = (10, 7)
C -A = (0, 20) -(15, 3) = (-15, 17)
Then the perpendicular bisector equations can be written as ...
bisector of AB ⇒ 10(x -20) +7(y -6.5) = 0
10x +7x -245.5 = 0
bisector of AC ⇒ -15(x -7.5) +17(y -11.5) = 0
-15x +17y -83 = 0
These have coefficients that aren't particularly nice, so a method similar to Cramer's Rule is suitable for solving this pair of equations. Using the "cross multiplication method", we have ...
x = (7(-83) -17(-245.5))/(10(17) -(-15)(7)) = 3592.5/275 = 13 7/110 ≈ 13.06
y = (-245.5(-15) -(-83)(10))/275 = 4512.5/275 = 16 9/22 ≈ 16.41
The point as far as possible from each town within the boundary of the island has coordinates (13.06, 16.41).
_____
Further detail regarding the solution
Here, we have written the equation for the perpendicular bisector this way. The difference in coordinates between points R and S can be called ...
R -S = (∆x, ∆y)
The midpoint of segment RS can be called ...
(R +S)/2 = (h, k)
Then the line that is a perpendicular bisector of RS can be written as ...
∆x(x -h) +∆y(y -k) = 0
This is the form that is used above.
__
The "cross multiplication method" for solving a pair of general-form linear equations ...
ax +by +c = 0
dx +ey +g = 0
will give the solution as ...
1/(ae -db) = x/(bg -ec) = y/(cd -ga)
If you write the coefficients in two rows of four, the pattern of products and differences is easy to see.

slope = undefined & x-intercept = -13
The linear equation with undefined slope and an x-intercept of -13 is:
x = -13
Which is the equation of the line with an undefined slope and x-intercept of -13?
The general linear equation is written as:
y = a*x + b
Where a is the slope and b is the intercept of the y-axis.
And undefined slope is used only for vertical lines, where the slope (technically) tends to infinite.
These lines are of the form x = K, where K is a real number. (so we have x = constant)
And we know that the x-intercept is at x equal -13, with that we can conclude that the constant will be equal to -13, then the equation of the line is:
x = -13.

Dominic said that more students gave a presentation. Do you agree with Dominic? Use numbers and words to support your answer. *
Answer: Yes. Dominic is correct

We are informed that Two fifth of the students wrote a report. This also means that (2/5 × 100) = 40% = 0.4 wrote a report and 0.6 of the students gave a presentation.
From the decimals gotten, we can see that 0.6 is more than 0.4. Therefore, more students gave a presentation. This implies that Dominic is correct.

A. 120
В. 80
с. 100
D. 60
Answer:
120
Step-by-step explanation:
By the rule of opposite angles, we can determine that x=120 because:
AB is parallel to CD
120 degree angle (let's call it Y) is on AB
X (we can see that it is obtuse) is on CD
So, Y is congruent to X, vice versa, so x=120
