Answer : The solution must be more than 1.

Step-by-step explanation :

Let us assume the two fractions that are both greater than 1/2.

Example 1:

The first fraction is, \frac{3}{2}

The second fraction is, \frac{5}{2}

Now adding two fractions, we get:

\frac{3}{2}+\frac{5}{2}

=\frac{8}{2}

=4

Example 2:

The first fraction is, \frac{5}{2}

The second fraction is, \frac{7}{2}

Now adding two fractions, we get:

\frac{5}{2}+\frac{7}{2}

=\frac{12}{2}

=6

Example 3:

The first fraction is, \frac{2}{2}

The second fraction is, \frac{3}{2}

Now adding two fractions, we get:

\frac{2}{2}+\frac{3}{2}

=\frac{5}{2}

=2.5

From this we conclude that if we are adding two fractions that are both greater than 1/2 then the sum of the two fractions will always be greater than 1.

Hence, the solution must be more than 1.

If the altitude is √7, find the volume. 36√7 cu. units 18√7 cu. units 12√7 cu. units
rosijanka [135]

Answer:

Volume = 12\sqrt{7} cubic units

Step-by-step explanation:

Volume of the square pyramid is given as ⅓*area of base*height of pyramid.

Where,

Area of base = 6*6 = 36

Height of pyramid = altitude = \sqrt{7} units

Plug the values into the formula to find volume.

Volume = \frac{1}{3}*36*\sqrt{7}

Volume = 12*\sqrt{7}

Volume = 12\sqrt{7} cubic units

What is 12 divided by 1230 in long division
Bess [88]
It is 102.5. You made it kind of confusing at first by putting the divisor first in your question then putting your dividend, but I understand what you meant.

Thomas reads 2/9 of a book on Monday and 1/6 of it on Tuesday. He reads twice as many pages on Wednesday as on Tuesday. What fra
dezoksy [38]
1/18 is left. Thomas has 1/18 left of his book. How? What denominator can 9&6 relate to? 54? Sure, but it could be lower. How about 18? Ok. We have 18 because 9x2 and 6x3 both equal 18... 2/9 becomes 4/18 because 18 divided by 9 is 2. You multiply 2 with the two from 2/9. 1/6 becomes 3/18 because 18 divided by 6 is 3. You then multiply 3 with the one from 1/6. Put it together and TA-DA... Your answer is 1/18

Which statement is true about figures ABCD and A′B′C′D′? (1 point)
sladkih [1.3K]

Answer:

Step-by-step explanation:

A'B'C'D' is obtained by rotating ABCD 180° counterclockwise about the origin and then reflecting it across the x-axis.

A(2, -2) is mapped to A'(-2, -2)

B(1, -4) is mapped to B'(-1, -4)

C(0, -2) is mapped to C'(0, -2)

D(1, -1) is mapped to D'(-1, -1)

If we rotate counterclockwise 180°, every point (x, y) is mapped to (-x, -y):

A(2, -2) gets mapped to (-2, 2)

B(1, -4) gets mapped to (-1, 4)

C(0, -2) gets mapped to (0, 2)

D(1, -1) gets mapped to (-1, 1)

Reflecting these images across the x-axis will then map (x, y) to (x, -y):

(-2, 2) gets mapped to (-2, -2)

(-1, 4) gets mapped to (-1, -4)

(0, 2) gets mapped to (0, -2)

(-1, 1) gets mapped to (-1, -1)

These new coordinates are the same as A'B'C'D'.
