Solve x² - 6x - 7 = 0
Answer:
x= 7
x=-1
Step-by-step explanation:
- Multiply the coefficient of the first term by the constant 1 -7 = -7
- Find two factors of -7 whose sum equals the coefficient of the middle term, which is -6 .
-7+ 1 = -6
-Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -7 and 1.
x^2-7x+1x-7
- Add up the first 2 terms, pulling out like factors.

The bookstore has 37 women's magazines and 37 other magazines. What percentage of the magazines at the bookstore are women's magazines?
Answer: 50%
Step-by-step explanation:
Number of women magazines = 37
Number of other magazines = 37
Total number of magazines = 37 + 37 = 74
The percentage of the magazines at the bookstore that are women's magazines will be:
= Number of women magazines / Total number of magazines × 100
= 37/74 × 100
= 1/2 × 100
= 50%

Lukas depositó $ 3000 en una cuenta de ahorros que genera una tasa de interés del 3.7% compuesto anualmente. ¿Cuál es el valor total de la cuenta después de 5 años?
Answer:
El valor total de la cuenta después de 5 años es de $3,598.
Step-by-step explanation:
Para encontrar la respuesta, tienes que utilizar la fórmula para encontrar el valor futuro:
VF=VP*(1+i)^n
VF=valor futuro
VP= valor presente=$3000
i=tasa de interés=0.037
n=número de periodos de tiempo=5 años
Ahora, puedes reemplazar los valores en la fórmula:
VF=3,000*(1+0.037)^5
VF=3,000*(1.037)^5
VF=3,598
De acuerdo a esto, la respuesta es que el valor total de la cuenta después de 5 años es de $3,598.

If m Z1 = 11x + 5 and m2 = 8x - 15, find m2.
A.) 75
B.) 115
C.) 10
D.) 65
Answer:
D) 65
Step-by-step explanation:
<1 = 11x + 5
<2 = 8x - 15
These angles are supplementary so,
11x + 5 + 8x - 15 = 180
19x - 10 = 180
19x = 190
x = 10
m<2:
8x - 15
8(10) - 15
80 - 15

Use the evidence you gathered to tell the story of a hypothetical indigenous
community in the Americas and its experience involving the Columbian Exchange.
Come up with a community whose circumstances are typical of many in Central
America, the West Indies, or another part of the Americas that had direct contact with
Europeans. Tell the story in chronological order, but feel free to skip whole years or
decades so that you can cover each of the important topics related to the activity: the
availability of goods, the effects of disease, and the impact of European culture
(language and religion, for example), at the very least.
Think of your story as more of a summary than a work of fiction; you must cover a
large span of time in few words. Base the details of the story on factual evidence and
cite your sources, but keep in mind that the text should be written as a story, not as
an essay with a conventional introduction, body, and conclusion. Aim for about 700

A staircase has a height of 14ft and a slant length of 52ft.
Answer:
50.1ft approx
Step-by-step explanation:
Given data
Height=14ft
Slant height= 52ft
Applying Pythagoras theorem, we can solve for the horizontal lenght
we know that
hyp^2= Opp^2+Adj^2---------- Pythagoras theorem
52^2=14^2+x^2
2704=196+x^2
2704-196=x^2
2508=x^2
x= √2508
x=50.07
Hence the horizontal distance is 50.1ft approx
Find the circumference of the semi circle 7cm
Given:
A semicircle with radius 7 cm.
To find:
The circumference of the given semi circle.
Solution:
We know that,
Circumference of a semi circle = Half of circumference of the circle + Diameter
[tex]=\dfrac{1}{2}(2\pi r+d[/tex]
[tex]=\pi r+2r[/tex]
Putting [tex]\pi=\dfrac{22}{7},r=7[/tex], we get
Circumference of the semi circle [tex]=\dfrac{22}{7}(7)+2(7)[/tex]
[tex]=22+14[/tex]
[tex]=36[/tex]
Therefore, the circumference of the given semi circle 36 cm.

Simon bought a 10-pound bag of cat food. He gives his cat 0.3 pound of food per day. Which equation with two variables to describe how the amount of cat food in the bag changes over time.
Answer:
y = 10 - 0.3t
Step-by-step explanation:
Amount of cat food purchased= 10 pounds
Daily pounds fed to dog = 0.3 pounds
How the amount of cat food in bag changes over time ;
Let y = amount of cat food left in bag
t = number of days since cat food was purchased
Amount of cat food left in bag = amount of cat food purchased - (daily pounds fed to dog * Number of days since cat food was purchased)
y = 10 - 0.3t
