He wants the page to have one of each of the four varieties on it. There are 9 daisies to choose from, 7 roses, 5 dandelions, and 2 pansies, so there are
9*7*5*2 = 630
ways of arranging one of each on the page.
Answer: 6 fishes
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a sphere = 4/3 x π x (diameter/2)^3
Replacing with the values given:
V = 4/3 x π x (20/2)^3
v = 4/3 x π x (10)^3 = 4,188.79 in3
Finally, we have to divide the volume of the fish tank by the volume that each goldfish needs.
4,188-79 / 693 = 6.04 = 6 fishes

<span>. 2 verbal expression
of 2d
Verbal expressions in mathematics is the
translation of the given mathematical equation or numbers into words. For
example the verbal expression of operations are:
+ = addition
- = subtraction
/ - division
x = multiplication
In the given number of 2d, these are the two verbal expression:
2d => 2 times d; or 2 multiply by d
2d => the product of 2 and d
Verbal expression are the words translation of mathematical equations.

Answer:
x = 125°, y = 55°, z = 70°
Step-by-step explanation:
x and 55 are adjacent angles and are supplementary, sum to 180°, that is
x + 55° = 180° ( subtract 55° from both sides )
x = 125°
∠ ABD and ∠ BDC are alternate angles and congruent , so
y = 55°
Since BD and BC are congruent, then Δ BCD is isosceles, so
∠ BDC = ∠ BCD = 55° and
z = 180° - (55 + 55)° ← angle sum of triangle
= 180° - 110°
= 70°
