Answer:
Step-by-step explanation:
3x2−2x−5=0
Let us factorize using the split the middle term method.
On inspection we observe that middle term can be split in two parts whose product is equal to the product of first and third term.
Two terms are −5xand3x
The equation becomes
3x2+3x−5x−5=0, pairing the two and taking out common factors
⇒(3x2+3x)−(5x+5)=0,
don't forget to change the sign of −5 once placed inside the parenthesis.
⇒3x(x+1)−5(x+1)=0
⇒(x+1)(3x−5)=0
Either (x+1)=0 or (3x−5)=0
We obtain x=−1,53
or x=−1,123
Answer:
$9.64
Step-by-step explanation:
1 pound = $1.89
x2.7 x2.7
2.7 pounds = $5.10
1 pound = $1.89
x2.4 x2.4
2.4 pounds = $4.54
$5.10+$4.54=$9.64
Answer:
16,244.55
Step-by-step explanation:
Original cost of piano = 19,100
19% off on 19,100 = 0.19*19100 = 3,629
Selling cost = 19100 - 3629 = 15471
Sales tax = 5% =0.05
Amount of sales tax = 0.05*15471 = 773.55
Total selling cost of piano = Selling cost + Amount of sales tax = 15471 + 773.55 = 16,244.55
Answer:
The answer is C.
Step-by-step explanation:
Given the line segment ST. we have to give the instruction to construct the perpendicular bisector of line ST.
So to construct the perpendicular bisector of line our first step is to place the compass at one end of line and then adjust the compass more than half of line segment and draw the arc on each side of segment.
After that Keeping the same compass width, draw arcs from other end of line. Place scale where the arcs intersect, and draw the line segment.
So, the correct match is option C ) Place the compass point on point S and open the compass so that the pencil point is on the segment, but closer to point T than to point S. Draw an arc on each side of segment.
Ben drinks 1,050 liters of tea every 6 days.
<h3>How many liters of tea does Ben drink every 6 days?</h3>
Convert the object's dimensions into centimeters before performing the volume calculation in liters. Next, determine a shape's volume using the volume formula. The metric unit for measuring volume or capacity is the liter (or liter). Liters are a standard unit of measurement frequently used to measure liquids.
Divide Bens daily tea usage by the number daily tea usage rate.
Ben the camel drinks tea ( so classy ).
He drinks 350 liters of tea every 2 days.
liters (Volume) = usage times /days
350 × (6/2)
= 350 × 3
= 1,050 liters of tea does Ben drink every 6 days.
As a result, Ben drinks 1,050 liters of tea every 6 days.
