Points D and E are midpoints of the sides of triangle ABC. The perimeter of the triangle is 48 units.
Q: what’s the value of t?
a) 2
b) 3
c) 6
d) 8
The value of t = 2. Option a) 2 is the correct answer.
Step-by-step explanation:
Perimeter is the sum of three sides of a triangle.
Given that, the points D and E are midpoints of the sides.
Therefore,
side AB= AD+DB
AB= 3t + 3t = 6t
side BC= BE+EC
BC= 4t + 4t = 8t
side AC= 7t+6
Perimeter of the triangle= sum of (side AB+side BC+side AC)
48 = 6t+8t+7t+6
48 = 21t+6
t= 42/21
t= 2
The inequality 9 - 4x< 3x - 5 is equivalent to:
A. x> -2
B. x> 2
c. x <2
D.x< -2
Answer:
B
Step-by-step explanation:
move x to one side and numbers on another side.
9+5<3x+4x. --» 14<7x. --»/7--» x>2
Final answer:
The inequality 9 - 4x < 3x - 5 simplifies to x > 2 after collecting like terms and performing basic algebraic operations. Therefore, the correct answer is B. x > 2.
Explanation:
To solve the inequality 9 - 4x < 3x - 5, we need first to collect like terms on one side. This step involves moving all the x terms to one side of the inequality and the constant terms to the other side.
Let's do this now:
Add 4x to each side: 9 - 4x + 4x < 3x - 5 + 4x, which simplifies to 9 < 7x - 5.Next, add 5 to each side: 9 + 5 < 7x - 5 + 5, which simplifies to 14 < 7x.Finally, divide each side by 7: 14/7 < 7x/7, which simplifies to 2 < x.The answer is x > 2, which corresponds to option B.

Answer this question please.
Answer:
see explanation
Step-by-step explanation:
The side of the square = x + 2, thus area is equal to
(x + 2)² ← expand using FOIL
= x² + 4x + 4
Given area = 7 then
x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required
Answer:
the area of the square ABCD = 7
on the other hand, the area of the square ABCD = (2+x)² = x² + 4x + 4
then x² + 4x + 4 = 7
then x² + 4x + 4 = 4 + 3
then x² + 4x = 3

D(-2,3) E(4,-1) F(2,-4) G(-4,0)
slope DG: (0-3)/(-4+2) = -3/-2 = 3/2
slope EF: (-4+1)/(2-4) = -3/-2 = 3/2
DG // EF
slope DE: (-1-3)/(4+2) = -4/6 = -2/3
slope GF: (-4-0)/(2+4) = -4/6 = -2/3
DE // GF
slope DG = - 1/slope DE
DG ⊥ DE
The same reason
DG ⊥ GF
DE ⊥ EF
EF ⊥ GF
∴ DEFG is a parallelogram with four 90° interior angles, it's a rectangle
In scoop county 16.8% of residents have diabetes. If 12,914 scioto county residents have diabetes, what is the population of the county
The population of the county is 76,869.
Step-by-step explanation:
Given,

Bernie gets twice as much as Eddy who gets three times as much as Gery.
Work out how much they each get.
Answer:
Gery will get 45 £,Eddy will get 135 £ and Bernie will get 270 £ of the total share.
Step-by-step explanation:
Given:
Bernie, Eddy and Gery share £450.
Bernie gets twice as much as Eddy.
Eddy gets three times as much as Gery.
So,
Let Gery gets 'x' share of the amount.
Then,
Eddy's share will be '[tex]3x[/tex]'
and
Bernie's share will be [tex]2\times 3x=6x[/tex]
According to the question.
Total share summation of total share = [tex]450[/tex]
⇒ [tex]x+3x+6x=450[/tex]
⇒ [tex]10x=450[/tex]
⇒ [tex]x=\frac{450}{10}=45[/tex]
So Gery's share = 'x' [tex]= 45[/tex]
Eddy's share = [tex]3x=3\times 45=135[/tex]
Bernie's share = [tex]6x=6\times 45=270[/tex]
Gery will get 45 £,Eddy will get 135 £ and Bernie will get 270 £ of the total share.

Initial value: 12, rate of change: 2
Initial value 8, rate of change: -2
Answer:
Initial value: 12, rate of change: -2
Step-by-step explanation:
The rate of change is given by change in the y-values over change in x-values.
There is a constant change of -2 in y-values.
There is also a constant change of 1 in the x-values.
The rate of change is -2
The initial value is when x=0,
So we go back one step, and that will give us (0,12)
Therefore the initial value is 12.

Answer:
1 hour 20 minutes
Step-by-step explanation:
It takes twenty minutes to finish a quarter of one level. Which indicates that it would take one hour and twenty minutes to finish said level by simply multiplying twenty by four.
George will complete a level on his computer games in 1 1/3 of the hours.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have been given that he finished 1/4 of a level on his computer games in 1/3 of an hour at this rate.
Let x the number of hours will it take to complete on a level
According to the given question, we can write the ratio would be as:
1/4 of a level : 1/3 of an hour = 1 level : x hour
⇒ (1/4) / (1/3) = 1/x
Apply the cross-multiplication operation,
⇒ x = (1/3) × 4
⇒ x = 4/3
⇒ x = 1 1/3
Therefore, there will be 1 1/3 of the hours it takes to complete a level.

How much greater is the area of a circle with a radius of 6.2 inches than the area of a square with a side length of 4 inches?
Answer:
7.54 times greater.
Step-by-step explanation:
The square with a side length of 4 inches has a 4×4=16 inches squared area. The area of a cirkel is calculated with the formula \pi×r^2. Using the 6.2 inch radius given, we get \pi×6.2^2=120.76 inches squared. 120.76/16=7.54 times greater.
Final answer:
Calculate the difference in area between a circle and a square given their respective dimensions.
Explanation:
To find the area of a circle with a radius of 6.2 inches:
Calculate the area using the formula A = πr², where r = 6.2 inches.Area of circle = π x (6.2)² = 38.48 square inches.To find the area of a square with a side length of 4 inches:
Calculate the area of the square using the formula A = s², where s = 4 inches.Area of square = 4 x 4 = 16 square inches.Subtract the area of the square from the area of the circle to find the difference:
Difference = 38.48 - 16 = 22.48 square inches.

The number of banks in a country for the years 1935 through 2009 is given by the following function.
81.8x + 12,361 if x < 90
f(x) = 3
where x is the number of years after 1900
- 376.4x + 48,685 if x 290
Complete parts (a) (b)
a) What does this model give as the number of banks in 1970? 1990? 2010?
The number of banks in 1970 is
Answer:
1990
Step-by-step explanation:
The number of banks in 1970 is 18,137, in 1990 is 3, and in 2010 is 7,250.
(a) Since 1970 is 70 years after 1900,
use the function f(x) = 81.8x + 12,361 for the years before 1990 (when x < 90).
f(70) = 81.8 * 70 + 12,361
= 5776 + 12,361
= 18,137
The number of banks in 1970 is 18,137.
(b) Since 1990 is exactly 90 years after 1900,
use the other part of the function f(x) = 3 for the years between 1990 and 2010.
f(90) = 3
The number of banks in 1990 is 3.
(c) Since 2010 is 110 years after 1900, use the function
f(x) = -376.4x + 48,685 for the years after 290 (when x > 290).
f(110) = -376.4 * 110 + 48,685
= -41404 + 48,685
= 7250
The number of banks in 2010 is 7,250.
So, the number of banks are 18,137, 3 and 7,250.

Marys watch keeps perfect time and Bills watch loses 4 minutes a day.
Both watches are set at midnight on January 1. How many times a year will they match?
Bill's and Mary's watches will match once a year on a non-leap year and twice a year on a leap year since Bill's watch loses 4 minutes per day. After 360 days, Bill's watch will be exactly 24 hours behind Mary's.
You asked how many times a year Mary's watch (which keeps perfect time) and Bill's watch (which loses 4 minutes a day) would match if they were both set at midnight on January 1. This is a mathematical problem involving the concept of elapsed time.
Since Bill's watch loses 4 minutes per day, after 1 day, there will be a 4-minute difference between the two watches. As this pattern continues, we calculate how many days it will take for Bill's watch to lose an entire 24-hour cycle (1440 minutes) since 1440 minutes divided by 4 minutes/day equals 360 days. Therefore, Bill's watch would match Mary's watch exactly one more time, 361 days after both watches were set, which would be on the next New Year's Eve, just before both watches hit midnight.
However, this scenario would only occur in a non-leap year. During a leap year, Bill's watch would be 4 minutes slow on December 30th instead of on December 31st, so Bill's watch would match Mary's watch two times in a leap year, once on January 1st and again on December 30th. In conclusion, Bill's and Mary's watches match once a year during a non-leap year and twice during a leap year.
