Answer:
El número de facturas
5 lempiras = 10 billetes
20 lempiras = 15 billetes
Step-by-step explanation:
Vamos a representar
El número de facturas de
5 lempiras = x
20 lempiras = y
Nuestro sistema de ecuaciones se da como:
x + y = 25 ..... Ecuación 1
x = 25 - y
5 × x + 20 × y = 350
5x + 20y = 350 .... Ecuación 2
Sustituiríamos x por 25 - y en la ecuación 2
5 (25 - años) + 20y = 350
125 - 5 años + 20 años = 350
125 + 15 años = 350
15 años = 350 - 125
15 años = 225
y = 225/15
y = 15
Resolviendo para x
x = 25 - y
x = 25 - 15
x = 10
Por lo tanto, el número de facturas
5 lempiras = 10 billetes
20 lempiras = 15 billetes
Match each power of a power expression with its simplified expression
= 4⁰×-⁹
= 4⁰
(-4⁹)²= -4⁹ײ
= -4¹⁸
=( -4)¹⁸
(4-³)-³= 4-³ × -³
= 4⁹
(4⁶)-³= 4⁶ × -³
= 4-¹⁸
= 1/4¹⁸

Rita is spending more time at home to study and practice math. Her efforts are finally paying off. On her first assessment she scored 58 points, then she scores 63 and 68 on her next two assessments. If her scores continued to increase at the same rate, on which assessments will she be scoring above 85? Select all that apply.
Answer:
7th
Step-by-step explanation:
63 - 58 = 5
68-63 = 5
She is adding 5 points each time
a1 = 58
d = 5
a2 = 63
a3 = 68
a4 = 58+5 = 73
a5 = 73+5 = 78
a6 = 78+5 = 83
a7 = 83+5 = 88
This is the first assessment greater then 85, so the 7th assessment

Answer:
Your answer would be the third one
Step-by-step explanation:
Triangle 1 - 73, 45
Triangle 2 - 47, 30
Triangle 1: 105°, 23° and Triangle 2: 52°, 105 are similar.
Option (4) is correct.
What is a Triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices.
As per the given data:
We are given two angles for each pair of triangles, and we have to find out which of the pair of triangles are similar.
For any two triangles to be similar, it must have 2 angles which are having the same measure.
For, Triangle 1: 55°, 45° and Triangle 2: 55°, 80°
Only one angle is same, hence not similar.
Triangle 1: 103°, 32° and Triangle 2: 103°, 25°
Only one angle is same, hence not similar.
Triangle 1: 73°, 47° and Triangle 2: 47°, 30°
Only one angle is same, hence not similar.
Triangle 1: 105°, 23° and Triangle 2: 52°, 105
By using angle sum property in Triangle 1 the remaining angles is:
= 180 - (105 + 23) = 52°
By using angle sum property in Triangle 2 the remaining angles is:
= 180 - (52 + 105) = 23°
2 angles are same, hence similar.
Triangle 1: 99, 41° and Triangle 2: 40°, 99°
Only one angle is same, hence not similar.
Hence, Triangle 1: 105°, 23° and Triangle 2: 52°, 105 are similar.

Use an algebraic approach to solve the problem.
If a ring costs a jeweler $1500, at what price should it be sold to yield a profit of 50% on the selling price?
Answer:
$2250
Step-by-step explanation:
selling the ring at 100% of $1500 would equal 1500 and yield no profit
therefore, you must sell the ring at 150% (where 100% covers the cost and the additional 50% provides the profit) of 1500
1.5 x 1500 = 2250
what is an expression showing the sum of 5 less than the number k
Answer:
5<k
Step-by-step explanation:
Answer:
k-5
Step-by-step explanation:
So, lets go over each part of the sentence, and turn it into a expression.
So it first says sum. This means addition, so we can start our expression with:
+
Next is says of 5. So we know its the addition of 5:
+5
Next it says less than. So now we know less than, which is subtraction. So we can swap the addition sign for a - sign:
-5
Finally it says the number k. So we know that the subtracted value is k:
k-5
So this is your expression!

Find the 25th term of the sequence -7,-22,-37.
Answer:
a₂₅ = - 367
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = - 22 - (- 7) = - 37 - (- 22) = - 15
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 7 and d = - 15 , then
a₂₅ = - 7 + (24 × - 15) = - 7 - 360 = - 367

Suppose you roll a cube 30 times, what is a to describe the theoretical of rolling a 1, 4, 6, 7 Please help me!
Answer:
[tex]Pr(x) = \frac{1}{6}[/tex]
Step-by-step explanation:
Given
[tex]n = 30[/tex] --- number of rolls
Required
The theoretical probability of rolling: (a) 1 (b) 4 (c) 6 (d) 7
Assume the cube is 6 sided.
The sample space is:
[tex]S = \{1,2,3,4,5,6\}[/tex]
And the probability of each is:
[tex]Pr(x) = \frac{1}{6}[/tex]
Irrespective of the number of rolls, the theoretical probability of (a). (b), (c) and (d) is:
[tex]Pr(x) = \frac{1}{6}[/tex]
The length of the ladder that will run from the ground to the door of the tree house is nine feet. The plan recommends that the rungs of the ladder be spaced at 8-inch intervals. The first and last rung should be 6 inches from the respective ends. How many rungs will the tree house ladder have?
Answer:
13 Rungs
Step-by-step explanation:
According to the Question,
Given, The length of the ladder that will run from the ground to the door of the treehouse is 9 feet ( 9 × 12 = 108 inches).The plan recommends that the rungs of the ladder be spaced at 8-inch intervals.
And, The first and last rung should be 6 inches from the respective ends.Thus, the rungs Cover on 108 -(6+6) = 96 inches with 8-inch gaping between each rung.
Therefore, the Total Rungs on the treehouse ladders have (96/8)+1 ⇒ 13 Ladders.The following box plot represents the average heights of the students in Mrs. Hill's sixth grade math class.

Dan rolls a fair dice and flips a fair coin what is the probability of obtaining an even number and a head
Half the numbers on the die are even so you have a 1/2 probability of getting an even number. There is also. 1/2 probability of getting heads on a coin flip.
To find the probability of both happening, multiply the probability of each together:
1/2 x 1/2 = 1/4
The probability of getting an even number and heads is 1/4

.Find x in the following figure. plss helpp need ans asap!
Answer:
80
Step-by-step explanation:
This is a pentagon (5 sides), n=5
The sum of internal angles equals (n-2)*180 = 540°
We have
A = 90
B = 180-40
C = 180-x
D = 180-60
E = 180-90
Sum all the angles to equal 540°
90 + 180-40 + 180-x + 180-60 + 180-90 = 540
620-x = 540
solve for x
x = 620 - 540 = 80
Answer:
80
Step-by-step explanation:
the answer should be 80 just as mathmate explained
