Answer:
You should add 
.
Step-by-step explanation:
In order for 
+ _ to equal 4, the numerator would have to equal 6 times the denominator after you add the number.
The denominator is 4, so the numerator should be 4 × 6, which equals 24. You should add something to make the numerator equal 24 and keep the denominator 4.
number = (24 - 23)/4 = 1/4
You should add .
7 L of paint is needed to cover 70m2. For 40m2, you can see that 4 L is needed, which means that for every 1 L, 10m2 can be covered. Multiply 1 L and 10m2 by 7, and you get 7 L is needed for 70m2.
Answer:
C. <1 = <4 and <2 = <3
Step-by-step explanation:
When two lines are parallel, the angles that are formed have certain properties.
There is a pair of angles in particular called alternate interior angles; these are basically the angles within the parallel lines. They are always equal to each other. Here, we will use the fact that AB || CD.
AB and CD create the angles 1 and 4. Angles 1 and 4 are alternate interior angles, so they are equal: <1 = <4
Similarly, we need to use the fact that AD || CB. These two parallel lines create the angles 2 and 3. We can see that because these two angles are "within"/formed by the parallel lines, they are alternate interior so they equal: <2 = <3.
Thus, the answer is C.
Hope this helps! (Sorry about the delay!!)
The answer is B, with a translation the segement size doesn’t change.
Answer:
The answer is given below
Step-by-step explanation:
The question is not complete. The correct question is:
A square based pyramid have a height of 30 cm and base of 10 cm. The The square based pyramid is cut horizontally at a height of 15cm to leave this frustum.
Answer:
The frustum would have a base of 10 cm and height of 15 cm. The lower base has a length of 10 cm. to calculate the upper base, we use the formula:
Substituting:
The volume of the frustum is given by the formula:
Where h is the height of the frustum = 15 cm, A1 is the area of the lower base = 10 * 10 = 100 cm², A1 is the area of the upper base = 5 * 5 = 25 cm²
Substituting gives:
