Answer:
El capicúa es 707.
Step-by-step explanation:
(The following exercise is presented in Spanish and for such reason explanation will be held in that language).
Un capicúa es un número que se lee de la misma manera tanto de derecha a izquierda como de izquierda a derecha. En este caso, el capicúa mencionado en el enunciado es el siguiente:
El capicúa es 707.
Given:
The figure of a circle.
To find:
The measure of arc AD and measure of each arc.
Solution:
The measure of arc is equal to the central angle of that arc.
The central angle of arc AD is 105 degrees. So,
The central angle of arc BC is 35 degrees. So,
The central angle of arc CD is 50 degrees. So,
The central angle of a complete circle is 360 degrees. So,
Therefore, the measure of arc AD is 105°, the measure of arc BC is 35°, the measure of arc CD is 50° and the measure of arc AB is 170°
Answer:
A
Step-by-step explanation:
In the figure attached, the complete question is shown.
We have to transform all the fractions to new fractions with the same denominator, as follows:
1/8 *4/4 = 4/32
-3/16 *2/2 = -6/32
-1/4 *8/8 = -8/32
1/32
5/32
-1/16 *2/2 = -2/32
Now we can order the list simply comparing numerators:
-8/32, -6/32, -2/32, 1/32, 4/32, 5/32
or
-1/4, -3/16, -1/16, 1/32, 1/8, 5/32
answer:
N(t)=2×
17
15
step by step explain:
before lesson (t=0), she knows 2 words.
after a week (t=1), she knows
2×(1+70%)=3.4 words
after one more week (t=2), she knows
3.4×(1+70%)=5.78 words
one more week later (t=3), she knows
5.78×(1+70%)=9.826 words
and so on ...
from pattern shown above, we know that she knows
2× words after t weeks
so N(t)=2×
after 4 weeks (t=4), she knows 2×=16.7042≈17 words
for learning 5000 words, she need:
2×=5000
=2500
t log(1.7)=log(2500)
t=
=14.7448727
≈15 (round up)
