Answer:
$25
Step-by-step explanation:
the fruit vendor sold 75-10 = 65 kg of bananas. 65*28 = 1820 dollars. so the fruit vendor earned 1820 dollars.
since she lost 55 dollars, 75 * cost = 1875, divide by 75 to get cost = 25
Angela bought a bookmark in the shape of an arrow as shown below. The base and height of the triangle are both 3 inches.
The area of a 2D form is the amount of space within its perimeter. The area of the arrow is 11.25 in².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
For the given problem, the image is given below.
The area of the arrow is,
Area = Area of rectangle + Area of triangle
= (1.5 in × 4.5 in) + (0.5×3×3)
= 6.75 in² + 4.5 in²
= 11.25 in²
Hence, the area of the arrow is 11.25 in².

The dimensions of a rectangular prism are shown below:
Length: 1 1/3 feet
Width: 1 foot

A) 84 cubes
B) Volume = 4 x 3 x 7 = 84 small cubes
[tex]\sf Volume=3 \frac{1}{9}\:\:ft^3[/tex]
Step-by-step explanation:
Part AAs the lengths of each side of the small cube are ¹/₃ ft each, to find the number cubes in the rectangular prism, first find how many thirds are in each dimension of the prism:
[tex]\sf Length=1 \frac{1}{3}\:ft=\dfrac{4}{3}\:ft=4\:thirds[/tex]
[tex]\sf Width=1 \:ft=\dfrac{3}{3}\:ft=3\:thirds[/tex]
[tex]\sf height=2 \frac{1}{3}\:ft=\dfrac{7}{3}\:ft=7\:thirds[/tex]
Now simply multiply the number of thirds:
Number of cubes in prism = 4 x 3 x 7 = 84
Part BAs we have already found the dimensions of the prism in terms of the number of cubes, the volume of the prism in terms of the small cube is:
⇒ Volume = 4 x 3 x 7 = 84 small cubes
To find the volume of the prism in ft³, calculate the actual volume of the small cube:
[tex]\textsf{Volume of small cube}=\sf \dfrac{1}{3} \times \dfrac{1}{3} \times \dfrac{1}{3}=\dfrac{1}{27}\:ft^3[/tex]
Now multiply the volume in terms of number of cubes by the actual volume of a cube:
[tex]\begin{aligned}\textsf{Volume} &= \sf \textsf{Volume in cubes} \times \textsf{Volume of cube in ft}^3\\\\& = \sf 84 \times \dfrac{1}{27}\:ft^3\\\\& =\sf \dfrac{84}{27}\:ft^3\\\\& =\sf 3\frac{1}{9}\:ft^3\end{aligned}[/tex]

For the function f(x) = 3(x - 1)² + 2, identify the vertex, domain, and range.
Answer:
For the function f(x) = 3(x − 1)2 + 2, identify the vertex, domain, and range
Step-by-step explanation:
The vertex is (1, 2), the domain is all real numbers, and the range is y ≥ 2.
The vertex is (1, 2), the domain is all real numbers, and the range is y ≤ 2.
The vertex is (–1, 2), the domain is all real numbers, and the range is y ≥ 2.
Answer:
see explanation
Step-by-step explanation:
the equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
f(x) = 3(x - 1)² + 2 ← is in vertex form
with vertex = (1, 2 )
The domain of a parabola exists for all real values of x
domain : x ∈ R
the range of the parabola are the values of y from the y- coordinate of the vertex, upwards.
range : y ≥ 2

Suav left his house at time zero and drove to the store, which is 8 blocks away, at a speed of 4 blocks per minute. Then he stopped and went into the store for 2 minutes. From there, he drove in the same direction at a speed of 4 blocks per minute until he got to the bank, which is 16 blocks away from the store. He stopped at the bank for 4 minutes. Then he drove home at a speed of 6 blocks every minute. Make a graph of showing the number of blocks away from home that Suav is xx minutes after he leaves his house, until he gets back home.
The graph for Suav's trip is attached along with the values derived from the information provided.
What is the explanation for the graph?The key to understanding the graph is that every time spent while he was on the way to the back and back are all added cumulatively.
So when he stops at the store which is 8 blocks away from home, the time spent is recorded as 4 + 2 at location 8 blocks.
It is also to be noted that the time spent is plotted on the x-axis and the blocks away from home on the y-axis.
