Which statements are true?
Select each correct answer.
All squares are rhombuses.
All parallelograms are quadrilaterals.
All rectangles are squares.
All rhombuses are rectangles.
Answer:
the true statement is
All parallelograms are quadrilaterals
Step-by-step explanation:
The answer is that ''All squares are rhombuses'' and ''All parallelograms are quadrilaterals.'' It can't be ''All rectangles are squares.'', because it is not valid. But if it were the other way around it would be correct. It can't be "All rhombuses are rectangles." because it's not valid. Only some can be rectangles.

12. Write a function rule in slope-intercept form for the statement: the output is one less than half of the opposite of the input.
Answer:
The function rule is:
[tex]y=-\frac{1}{2} x-1[/tex]
Step-by-step explanation:
We identify the output with the variable "y", the "input with the variable"x". Notice also that the "opposite of the input is "-x" (negative x), and therefore the words "the output is one less than half of the opposite of the input" translate into:
[tex]y=\frac{1}{2} (-x)-1\\y=-\frac{1}{2} x-1[/tex]

What is a word problem?A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Total number of people = 754
The ratio of students to teachers = 27:2
Let x be the number of people
then,
⇒ [tex]27x+2x=274[/tex]
⇒ [tex]29x=274[/tex]
⇒ [tex]x=\frac{274}{29}[/tex]
⇒ [tex]x=26[/tex]
Thus number of students = [tex]27x[/tex]
⇒ [tex]27(26)=702[/tex]
and number of teachers = [tex]2x[/tex]
⇒ [tex]2(26)=52[/tex]
Hence we can conclude that the number of teachers are 52.

Paloma added a garden to her painting. She has 12 rows of flowers. Each row has 13 plants in it. Each plant has 15 flowers on it. How many flowers are in Palomas garden?
Answer: 2340 flowers
Step-by-step explanation:
From the question, Paloma added a garden to her painting. She has 12 rows of flowers and each row has 13 plants in it while each plant has 15 flowers on it. To calculate the number of flowers in Palomas garden, we multiply the number of rows by the total number of plants and the number of flowers in each plant. This will be:
= 12 × 13 × 15

4. Kenneth needs to repaint a wall in his bathroom. The wall is 8 feet high and 14 feet long. Part of
the wall is covered with tile and he will not paint that part. The part of the wall covered by tile is 14
feet long and 42 inches high. Which expression could Kenneth use to find the area of the part of the
wall he needs to repaint?
a. 148-(42 + 8)
b. 14 * 8 - (42 * 14)
c. 148 -[(42 +12) * 14]
d. 2(14 + 8) -[(42 +12) + 14]
Answer:
96 * 144 - 168 * 42
Step-by-step explanation:
So the area of the wall is 96 * 144
And the area of the tiled part is 168 * 42
So it would be 96 * 144 - 168 * 42

Find the surface area of the suitcase
Answer:
1,344 square inches
Step-by-step explanation:
First, determine the faces that you have to find the areas of! In this situation, you need to find the areas of two trapezoids and four rectangles.
Finding the area of a trapezoid is pretty straightforward! Simply find the average of the two bases and multiply that by the height. ((5+15)/2)*12 should equal the area of one trapezoid. Because they're both the same trapezoid, you can multiply this area by two in order to get the area of both. This will get you 240.
Now, find the area of each of the rectangles by multiplying their individual bases and heights together. You'll find them to be 312, 360, 120, and 312.
Lastly, add all the areas together to get the total surface area.
A square is made using four rods of equal length joined end to end.
the perimeter of this square is 72 cm. Three of these rods are now joined end to end to make an equilateral triangle.
What is the perimeter of this equilateral triangle
Answer:54 cm
Step-by-step explanation:
Given
Rods are joined to form a square
Perimeter of square is [tex]72\ cm[/tex]
Suppose a is the length of each rod so
Perimeter is [tex]4 a[/tex]
[tex]\therefore 4a=72[/tex]
[tex]\Rightarrow a=\frac{72}{4}[/tex]
[tex]\Rightarrow a=18\ cm[/tex]
Now if rods are joined to form a square then
Perimeter is the sum of sides
Perimeter of (equilateral)triangle[tex]=3a[/tex]
[tex]\Rightarrow =3\times 18[/tex]
[tex]\Rightarrow =54\ cm[/tex]
Work out the perimeter of the shaded shape.
Answer:

1. Se tiene que 5 kilogramos (kg) de almendra y 4 kg de nuez cuestan $44.00, mientras que 8 kg de almendra y 6 kg de nuez cuestan $69.00. Encuentra el precio por kilogramo de cada producto.
Answer:
x = 6.00 $/kg ----> almond
y = 3.5 $/kg ------> nut
Step-by-step explanation:
To find the price per kg of each product you first write the algebraic equations for the given relations:
x : price per kg of almond
y: price per kg of nut
Then, you have:
5x + 4y = 44.00 (1)
8x + 6y = 69.00 (2)
By using substitution you have from (1):
y = (44.00-5x)/(4) = 11.00 - (5/4)x
you replace this expression for y into (2):
8x+6[11.00-(5/4)x] = 69.00
8x+66.00-(15/2)x = 69.00
8x-(15/2)x = 69.00 - 66.00
(1/2)x = 3.00
x = 6.00 $/kg ----> almond
And for nut:
y = 11.00 - (5/4)x = 11.00 - (5/4)(6.00) = 3.5$/kg
y = 3.5 $/kg ------> nut
What is the measure of angle a?
Answer:
38°
Step-by-step explanation:
Using the Cosine rule in Δ ABC
cos A = [tex]\frac{b^2+c^2-a^2}{2bc}[/tex]
where a, b and c are the sides of the triangle.
Here a = 5, b = 3 and c = 7 , thus
cos A = [tex]\frac{3^2+7^2-5^2}{2(3)(7)}[/tex] = [tex]\frac{9+49-25}{42}[/tex] = [tex]\frac{33}{42}[/tex] , thus
∠ A = [tex]cos^{-1}[/tex] ([tex]\frac{33}{42}[/tex] ) ≈ 38°

A line has a slope of 3/7. What is the slope of any line parallel to this line?
a) -7/3
b) 0
c) 3/7
d) 7/3
The slope of any line parallel to this line would be c) 3/7.
What are parallel lines?Parallel lines are those lines that are equal distances apart and often of the same length. So, for the given slope where we have parallel lines, we can expect to have lines of the same slope. Thus we can arrive at 3/7.
Note that parallel lines have the same slope. So, since the first slope is 3/7, we can expect the second to be the same thing.
