Tyra has 12 2/3 cups of sugar. If r is the amount of sugar called for in one batch of cookies, the expression 12 2/3 ÷ r can be used to find how many batches Tyra can make with the sugar she has. If r is 2/3 cup, how many batches of cookies can Tyra make?
Answer:
13 batches of cookies
Step-by-step explanation:
12 2/3 ÷ 2/3 = 12.6666667, it's 13 because 2/3 as a decimal is .6666666 and .6666667 is more than 2/3. So you add one to the answer.
Answer:
13
Step-by-step explanation:
because 12 23 divided by 2/3=12.6666667 so .6666667 is greater than 2/3, then simplify your answer to the closest value.

Joseph buys carrots for his horse every weekend. He paid $4.69 for 7 carrots at a farm stand last weekend. This weekend, Joseph paid $5.76 for 12 carrots at the supermarket. Which location offers the better deal?
Brainliest
Answer: The supermarket offers the better deal.
Step-by-step explanation: The supermarket offers a better deal because their carrots are only $0.48 a carrot and the farms stand carrots cost $0.67 a carrot. You can find this out by taking the price and dividing it by the number of carrots purchased. This will tell you the price per carrot.
jill has a rectangular table that is 3 1/2 feet long and 1 3/4 feet wide. what is the area of jill’s table?
Answer:
6 1/8 feet squared
Step-by-step explanation:
The Area of Jill's table is 49/ 8 feet².
What is area?The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area. The area of a plane figure is the space enclosed by its boundary. The number of unit squares that cover the surface of a closed form is the figure's area.
and, Area of Rectangle = length x width
We have,
Length of rectangular table = 3 1/2 feet = 7/2 feet
Width of rectangular table = 1 3/4 feet = 7/4 feet
So, the Area of rectangular table
= l w
= 7/2 x 7/4
= 49/ 8 feet²
Thus, the Area is 49/ 8 feet².

A triangle in Quadrant II is going to be reflected over the y-axis. Which of the following is a true statement? *
a. The image will be in Quadrant III.
b. The orientation of the figure will not change.
c. The orientation of the vertices will change.
d. The image and the pre-image will not be congruent
Answer:
b
Step-by-step explanation:
The following is a true statement; b. The orientation of the figure will not change.
How reflection across axis works?When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If we study it more, we will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
Thus, if you can reflecting a point (x,y) along x axis, then its x abscissa will stay same but y ordinates will negate. Thus (x,y) turns to (x, -y)
Similarly, if you can reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)
Given; A triangle in Quadrant II is going to be reflected over the y-axis.
Therefore, the following is a true statement; b. The orientation of the figure will not change.

Answer:

Step-by-step explanation:
The slope of a line is the rate of change
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 12 ) and (x₂, y₂ ) = (0, 4) ← 2 ordered pairs from the table
m = [tex]\frac{4-12}{0-2}[/tex] = [tex]\frac{-8}{-2}[/tex] = 4
y = 7x + 4 ← is in slope- intercept form
with slope m = 7
Difference between rates of change = 7 - 4 = 3

ABC is dilated by a factor of 1/2 to produce A'B'C'
Answer:
B
Step-by-step explanation:
34 x 1/2 = 17 (Line A'B')
28 x 1/2 = 14 (Angle A')
The length of A'B' and measure of angle A after the dilation are respectively: 15 & 28°.
What is the similarity of triangles?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"
By Pythagoras theorem we can check, the given sides do not form a right angle triangle.
Now, let's apply the dilation to the given triangle ABC.
Since the dilation factor is 1/2, the length of each side of A'B'C' will be half of the corresponding side of ABC.
So, the length of AB is 30 and the length of A'B' is 1/2 of AB, which is 15.
To find the measure of angle A', we need to use the fact that corresponding angles in similar triangles are congruent. S
ince ABC and A'B'C' are similar triangles, angle A is corresponding to angle A'. We know that angle A is 28 degrees, so angle A' must also be 28 degrees.
Therefore, the answer is D. A'B' is 15 and mZA' is 28°.
