What shape is both a rhombus and a rectangle?
A.triangle
B.trapezoid
C.Square
D.kite
The shape that is both a rhombus and a rectangle is a square (option a).
A square possesses the characteristics of both a rhombus and a rectangle. A rhombus is a quadrilateral with all sides of equal length, while a rectangle is a quadrilateral with four right angles. A square satisfies both conditions, as it has four equal sides and four right angles.
Therefore, a square can be classified as a rhombus because its sides are equal, and it can also be classified as a rectangle because it has right angles. The square is a special case where the properties of both a rhombus and a rectangle are met, making it the correct answer. The correct option is a.

Diver Dan enjoys scuba diving. He dives to 34 feet below the surface of a lake. His friend Jump in Jeff dives to 40 feet below the surface, but then descends 20 feet. What is the vertical distance between Dan and Jeff? Please show work.
Answer:
The vertical distance between Dan and Jeff is of 26 feet.
Step-by-step explanation:
Diver Dan enjoys scuba diving. He dives to 34 feet below the surface of a lake.
His position is -34 feet.
His friend Jump in Jeff dives to 40 feet below the surface, but then descends 20 feet.
Dives to 40 feet, and descends 20 more feet. So
-(40 + 20) = -60
What is the vertical distance between Dan and Jeff?
|-34 - (-60)| = |-34 + 60| = 26
The vertical distance between Dan and Jeff is of 26 feet.

Answer:
The answer is c! 7,36,60,30
Step-by-step explanation:
To answer this equation you have to find a number that fits the description of what is required. It may seem difficult but it's not first off it's trial and error you have to find the right equation for every given number. For example, what makes 15 equal 5 true? To make the equation true you have to do 15 divided by 3 equals 5 now we take the / 3 and apply them to all the other numbers so 21 / 3 is 7 , 36 divided by 3 is 12 hi, 60 / 3 is 20 , 90 /3 is 30. If you have any other question like this all you have to do is trial and error with a number to make the equation true hopefully that helps! (B.t.w / symbol means divided by)

Scarlett walks along the edges of a
rectangular path from A to B to C to D, a
distance of 38 metres. Jake walks along the
same rectangle, but from B to C to D to A,
a distance of only 31 metres.
What is the area, in square metres, of rectangle ABCD?
D
С
Answer:
168 meters squared
Step-by-step explanation:
So we know that Jake walked from b to c and d meaning he didn't go from a to b, but we also know that scarlet walked a to b so to find the length we can subtract scarlet's walk by jake's walk or 38-31 which is 7.
So we know the length of one side is 7 so this means we have side a to b and c to d, but we still need to know b to c. So what we can do is get the length of a b c and d and isolate it so that we only have b to c. To do this we get the length of 7 and double it which is 14 and take it away from the 38m
38-14=24
so now we know that the side is 24 and we can solve for the area
24*7=168
so the answer is 168 meters squared

Answer:
3. One Solution. (0,4). (they have different slopes and y-intercepts)
The solution can be found using elimination method:
Add the equations together
y = -x + 4
y = x - 4
2y = 0
y = 0
Solve for x
0 = x - 4
x = 4
(4, 0)
4. No solution
x + y = -2 and 3 which is not possible

What is the measure of the angle that the ladder makes with the wall?
Answer:
30°
Step-by-step explanation:
The measure of angle the ladder makes with the wall = 180 - (the measure of angle the ladder makes with the ground + 90°)
Measure of angle the ladder makes with the ground = 180 - 120 = 60°
Therefore,
The measure of angle the ladder makes with the wall = 180 - (60 + 90°)
= 30°

How many 2/3 cup servings are there in a container that holds 7 cups?
Answer:
7÷12=71×21=14 servings. So the operation you need to do is division. 8÷23. 81÷23 ← change 'divide' to 'multiply by the reciprocal'.
hope this helps
We want to see how many 2/3 cup servings are there in a container that can hold 7 cups, by taking the quotient we will see that there are 10.5 2/3 cup servings.
Taking the quotient:
To see how many times 2/3 cups fit in 7 cups, we just need to take the quotient between these two quantities, it gives:
[tex]N = \frac{7 cups}{(2/3) cups } = \frac{7*3}{2} = \frac{21}{2} = 10.5[/tex]
Where I used the rule:
[tex]\frac{A}{n/m} = \frac{A*m}{n}[/tex]
Then we can conclude that there are 10.5 2/3 cup servings in a container that holds 7 cups.

someone tell me the slope please
Answer:
[tex]\frac{0}{5}[/tex] or zero.
Step-by-step explanation:
The pair on the left is (-4, -5). The pair on the right is (1, -5).
In order to find the slope, you must first subtract the y in the first pair by the y in the second pair. Then what ever answer you get will be your numerator. Then, subtract the x in the second pair by the x in the first pair and that will be your denominator. So, in this case, it would be [tex]\frac{-5 - -5}{1 - -4}[/tex] which equals [tex]\frac{0}{5}[/tex]. If a zero is the numerator, that means that the fraction is zero. If the zero had been on the bottom, then the answer would have been undefined.
In short the formula to find slope is: [tex]y^{2}[/tex]- [tex]y^{1}[/tex] over [tex]x^{2}[/tex] - [tex]x^{1}[/tex].
What is the sale price of a bag of potato chips priced 4 and the sale 25% off?
A:$1.50 B:$2 C:$3 D:$2.50
Answer:
C: $3
Step-by-step explanation:
I think you're saying that the chips cost $4, so that's what I'm going with.
You can think of 25% as 1/4 of the whole. So if you divide 4 by 4, you get 1, so that means that 1/4 of the price is 1.
Now you can subtract 1 from 4 : 4-1= $3
Hope that helps!
