2 3/7 - 1 1/4 please give the answer as a mixed number with the fraction part in the lowest terms :))
Answer:
9/28Step-by-step explanation:
2 3/7 - 1 1/4
2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:
2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:17/7 - 5/4
2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:17/7 - 5/4Next find the Lowest Common Denominator:
L.C.D = 28
L.C.D = 2821 - 12/28
L.C.D = 2821 - 12/28= 9/28
It won't be a mixed number because the denominator is bigger than the numerator.

Answer: They are both right triangles so you can use the Pythagorean Theorem to get the length of the missing side
12^2 = 144. 5^2 = 25. 144 + 25 = 169. 13^2 = 169. Or you could say the sure root of 169 is 13.
Step-by-step explanation:
The triangles are congruent because the three sides of triangle A are equal to the three sides of triangle B.
In geometry they call that proof "sss" meaning 3 same sides. Or you could prove by "sas" 2 equal sides and an equal angle.

Susan plans to rent a bike in New Orleans to tour the city. The cost of the rental is $20 per day. The cost of a helmet is $7 for as long as Susan needs the bike. Barbara has $250 to rent a bike for 15 days. Does Barbara have enough money? Explain. First answer gets Brainiest and 48 points hurry please tho
Answer:
No, she does not.
Step-by-step explanation:
Using the words here, we can create the expression [tex]20d + 7[/tex] where d is the number of days.
We can now substitute 15 in as d, to see how much this will cost.
[tex]20\cdot15 + 7\\\\300+7\\\\307[/tex]
So the total cost will be $307.
Since $307 is more than $250, she does not have enough money.

5. The shape of a dome can be modeled by the equation h = - 2 d 2 + 100 where h is the height (in feet) of the dome from the floor d feet from its center. How far from the center of the dome is the height 50 feet?
6. A cab charges $0.10 per mile and a flat fee of $3.00. Write an equation to model the price y of an x-mile-long cab ride.
7. Use the discriminate to determine the number of solutions to the quadratic equation y = 3 x 2 - 4 x + 6. 8. If f ( x ) = 7 x 2 + 5, compute f ( )3 . 9. Write an equation representing the translation of f ( x ) = 7 x + 3 down 4 units.
Answer:
5. When the dome is 50 feet high, the distance from the center is 5 feet
6. The equation that model the price y of an x-mile long ride is given as follows;
y = 0.1×x + $3.00
7. The discriminant is < 0; The equation has no real root
8. f(3) = 68
9. The equation representing the translation of the line f(x) = 7·x + 3 down 4 units is f(x) = 7·x + 7
Step-by-step explanation:
5. The given equation for the shape of the dome is presented as follows;
h = -2·d² + 100
Where;
h = The height of the dome (in feet)
d = The distance from the center
Therefore, we have;
When h = 50, d is found as follows;
h = -2·d² + 100
50 = -2·d² + 100
50 - 100 = -2·d²
-50 = -2·d²
∴ 2·d² = 50
d² = 50/2 = 25
d = √25 = 5 feet
Therefore when the dome is 50 feet high, the distance from the center is 5 feet
6. The given rate the cab charges per mile, x = $0.10
The rate the cab charges as flat fee = $3.00
Therefore, the price, y a person traveling by cab for x miles is given by the straight lie equation as y = m·x + c,
Where;
m = the slope or rate which in this case = $0.1/hour
c = A constant term which in this case = $3.00
Therefore
y = 0.1×x + $3.00
The equation that model the price y of an x-mile long ride is y = 0.1×x + $3.00
7. The discriminant, b² - 4·a·c of the quadratic equation is (-4)² - 4×3×6 = -56
which is < 0, the equation has no real root
8. Given f(x) = 7·x² + 5
f(3) = 7 × (3)² + 5 = 68
f(3) = 68
9. The equation representing the translation of the line f(x) = 7·x + 3 down 4 units is given as follows;
Down 4 units is equivalent to subtracting 4 from the y-coordinate value, therefore, we have;
f(x) - 4= 7·x + 3
f(x) = 7·x + 3 + 4
f(x) = 7·x + 7
The equation representing the translation of the line f(x) = 7·x + 3 down 4 units is f(x) = 7·x + 7

how many centimetre square are there in a rectangle of 10cmby5cm
Answer:
30cm²
Step-by-step explanation:
Since there are two 10 centimeter sides, this can be shown as 10cm×2=20cm. Since there are two 5 centimeter sides, this can be shown as 5cm×2=10cm. 20cm+10cm=30cm².
Find all real zeros of the function f(x)= 12 A. 5,7 B. 12 C. 1 D. none
Answer:
D. NoneStep-by-step explanation:
Given the function f(x) = 12, the function is only a constant with no degree. For a function to have roots, it must have at least degree of 1. Let us write the function f(x) = 12 in terms of x
f(x) = 12x⁰
From the function above it can be seen that the introduction of x⁰ can not in any way affect the function of x because x⁰ will return 1.
From the function, it can be seen that the highest power of the variable x is zero. This means that the function has no roots.
Hence, there are no real zeros of the function.

Answer:
No
Step-by-step explanation:
Substitute (6, 10 ) into the left side of the inequality and compare value with right side.
8(6) + 2(10) = 48 + 20 = 68 > 2
Thus (6, 10 ) is not a solution of the inequality

Hadley buys 7 boxes of markers with 8
in each box. Delaney buys 6 boxes of
markers with 12 markers in each box.
How many markers did Hadley and
Delaney buy in all?
Answer:
128 markers.
Step-by-step explanation:
7 x 8 = 56
12 x 6 = 72
72+ 15 = 87
Hadley and Delaney therefore bought 128 markers all in total.
Hope I helped ! :))))))
The amount of markers Hadley and Delaney bought in all is equal to 128 markers.
Given the following data:
Hadley = 7 boxes of markers with 8 in each box.Delaney = 6 boxes of markers with 12 markers in each box.To determine the amount of markers Hadley and Delaney bought in all:
First of all, we would determine the total number of marker in each box.
For Hadley:
[tex]Hadley = 7 \times 8[/tex]
Hadley = 56 markers
For Delaney:
[tex]Delaney = 6\times 12[/tex]
Delaney = 72 markers
Now, we can find the total markers:
[tex]Total \;markers = Hadley + Delaney\\\\Total \;markers = 56+72[/tex]
Total markers = 128 markers

a body of mass 2kg travelling with a velocity of 10 m/s what is the momentum this body colloids with another body of equal mass travelling in the same direction with a velocity of 5m/s what is the total momentum of the 2 objects before and after coliision
Your question has been heard loud and clear.
M1 = 2kg , M2=2kg , V1=10m/s V2=5m/s
Total momentum before collision = M1V1+M2V2 = 2*10 + 2*5 = 30kgm/s
Now , by law of conservation of momentum ,
Total momentum before collision = total momentum after collision
Therefore , total momentum of objects before and after collision = 30kgm/s

Chloe wants to net 50000 on her house. Her closing costs will be 8000 plus 7% commission. She owes 200000 on her loan . What is the minimum contract price that she can accept for the property?
Answer:
$277,419
Step-by-step explanation:
Relevant Data provided as per the question is
Net amount = 50,000
Closing cost = 8,000
Loan amount = 200,000
Commission percentage = 7%
According to the given situation, the calculation of the minimum contract price is shown below:-
[tex]Minimum\ contract\ price = \frac{(Net\ amount\ +\ Closing\ cost\ +\ Loan\ amount) }{Remaining\ percentage}[/tex]
[tex]= \frac{(50,000 + 8,000 + 200,000)}{(100\% - 7\%)}[/tex]
[tex]= \frac{258,000}{93\%}[/tex]
= $277,419
Therefore for calculating the minimum contract price we simply applied the above formula.

write the equation of the line that passes through (3, 4) and (2,-1) in point slope form
Step-by-step explanation:
Using Point Slope formula :
[tex](y - y_1) = \frac{(y_2 - y_1)}{(x_2 - x_1)} (x - x_1)[/tex]
[tex](y - 4) = 5(x - 3)[/tex]
[tex]y = 5x - 11[/tex]
Answer:
The point slope formula is : y-y₁ =m(x-x₁), so first u need to find the value of slope.
Step-by-step explanation:
finding the value of slope:
slope(m)= y₂-y₁ ÷ x₂-x₁
= -1-4 ÷ 2-3
= 5
now finding equation;
y-y₁=m(x-x₁)
y-4 = 5(x-3)
11=5x - y
0= 5x - y -11
therefore equation of line in point slope is : 5x-y-11=0

The test for goodness of fit a. is always an upper tail test. b. is always a two-tailed test. c. can be a lower or an upper tail test. d. is always a lower tail test.
Answer: a. is always an upper tail test.
Step-by-step explanation:
The chi-square goodness-of-fit test is a test to check whether the sample comes from the population with the expected distribution or not.
If the observed frequency is close to the expected frequency, then the square of the deviations will be small. The square of the deviation is divided by the expected frequency to get the weighted frequencies.
If the sum of these weighted squared deviations is large is then it creates a doubt for the distribution claimed other wise not. Therefore, the chi-square goodness-of-fit test is always a right tail test.
Hence correct option is "a. is always an upper tail test. "
