! + 3 − 5 = 0; by completing the square
Answer:
x = 1.19258 and x = −4.19258
Step-by-step explanation:
The given equation is :
[tex]x^2+3x-5=0[/tex]
Keep x terms on the left and move the constant to the right side by adding it on both sides.
[tex]x^2+3x=5[/tex]
Take half of the x term and square it.
[tex](3\times \dfrac{1}{2})^2=\dfrac{9}{4}[/tex]
then add the result to both sides
[tex]x^2+3x+\dfrac{9}{4}=5+\dfrac{9}{4}\\\\(x+\dfrac{3}{2})^2=\dfrac{29}{4}\\\\(x+\dfrac{3}{2})=\sqrt{\dfrac{29}{4}}\\\\x=\dfrac{-3}{2}+\sqrt{\dfrac{29}{4}}\\\\x=\dfrac{-3}{2}-\sqrt{\dfrac{29}{4}}[/tex]
So,
x = 1.19258 and x = −4.19258
Hence, this is the required solution.

Answer:
x = 35
y = 95
Step-by-step explanation:
(For y) The measure of a line is 180 degress. 180 - 95 - 50 = 35.
(For x) The measure of a triangle is 180 degress. 180 - 50 - 35 = 95.
Answer:
x = 85, y = 45
Step-by-step explanation:
solving for x:
180 - 95 = 85
solving for y:
85 + 50 = 135
180 - 135 = 45

There are 750 people at a football game Out of this number 320 are students what percent of people at the football game are not students? Round to the nearest hundredth,if needed.
The percent of people at the football game are not students will be 57.33%.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
The number of peoples in football game = 750
The number of students = 320
Now.
Find the percent of people at the football game are not students as;
Number of people are not students = 750 - 320
= 430
Thus, The percent of people at the football game are not students is;
Percent = 430 / 750 x 100
= 0.5733 x 100
= 57.33%
Hence, The percent of people at the football game are not students will be 57.33%.

2x - 1/ 4
+ x/3 = 2
Answer:
= 2 7 /2 8
Step-by-step explanation:
Answer:
x = 1 1/8
Step-by-step explanation:
2x - 1/4 + x/3 = 2
2x + x/3 = 2 1/4 (added 1/4 to both sides)
6x = 6.75 (multiplied both sides by 3)

The sum of 8 and Jose's savings is 50.
Answer:
8 + x = 50, so Jose's saving or x = 42
Hope this helps!
Answer:
The equation is: s + 8 = 50
The amount of Jose's savings is: 42
Step-by-step explanation:
Let s = Jose's savings.
s + 8 = 50
Subtract 8 from both sides.
s = 42
The equation is: s + 8 = 50
The amount of Jose's savings is: 42
What is the length of the radius of a circle whose circumference is 125.6 feet? Use 3.14 for Pi.
Answer:
Hello! answer: 20
Step-by-step explanation:
circumference is just diameter × pi so If we do circumference ÷ pi we will get our diameter so
125.6 ÷ 3.14 = 40 But remember diameter is just twice the radius so all we have to do is divide by 2 to get our radius so
40 ÷ 2 = 20 So 20 is the radius Hope this helps!
Answer:
the answer is 20 feet
Step-by-step explanation:
divide the circumference by 3.14 gives you the diameter then divide the diameter by 2 to get the radius.

a car travels 156 miles in 3 hours and 15 minutes. how many miles does it travel per hour
Answer:
48 mph
Step-by-step explanation:
Convert 3 hours 15 minutes to hours.
15 minutes = 15/60 hour = 1/4
So 3 hours 15 mins = 3 1/4 hours = 13/4 hours
156 miles in 13/4 hours ==> speed = 156 ÷ 13/4 = 156 x 4/13 = 48

The plane region is revolved completely about the x-axis. Find its surface area in EXACT form (in terms of pi and/or with simplified radicals as necessary).
Answer: The Given plane region is missing attached below is the plane region
answer : 24 π or 75.40 sq. units
Step-by-step explanation:
Given data :
Height of plane region = 3
base of plane region = 4
When we revolved the plane region completely we will we forming a cone hence we will calculate for the surface area of a cone
Radius of the new cone = 3
Height of the cone = 4
slant height of the cone ( l ) = [tex]\sqrt{4^2 +3^2}[/tex] = 5
surface area of cone = πr^2 + πrl
= π ( 3 )^2 + π (3 ) ( 5 )
= 24 π or 75.40 sq. units

If a 5-foot tall man casts a shadow of 12 feet when standing on level ground, then the distance from the top of his head to the tip of his shadow is
Answer:
13 feet
Step-by-step explanation:
you can use the Pythagorean Theorem to solve this problem because the man standing on the ground forms a 90 degree angle
5² + 12² = c²
25 + 144 = c²
169 = c²
c = √169 which is 13

Step-by-step explanation:
1. For a one-tailed test (lower tail) at 93.7% confidence, Z =
2. For a one-tailed test (upper tail), a sample size of 24 at 90% confidence, t =
3. In a one-tailed hypothesis test (lower tail=left tailed test) and where the population standard deviation is known, the test statistic is determined to be -2.5. What is the p-value for this test?
Answer:
1) Z = -1.8592
2) t = 1.7139
3) p = 0.0062
Step-by-step explanation:
1) Area: (93.7+100)/2 = 193.7/2 = 96.85
Z = invNorm(0.9685,0,1) = 1.8592, but since the test is one-tailed at the lower tail, Z is actually -1.8592
2) Area: (90+100)/2 = 190/2= 95 where df=n-1=24-1=23
t = invT(0.95,23) = 1.7139
3) Since the population standard deviation is known, our test statistic is z=-2.5, making the p-value for the test p=normalcdf(-1e99,-2.5,0,1) = 0.0062
