If you can travel 120 miles in 3 hours (180 minutes), what is the distance you could travel in 75 minutes
a. 50 miles
C. 70 miles
b. 60 miles
d. 80 miles
Answer:
[tex]Speed = \frac{Distance}{Time } = \frac{120}{3} = 40mph[/tex]
T = 75minutes = (75/60) hours
[tex]Distance = Speed \times Time = 40 \times \frac{75}{60} =\frac{40\times 75}{60} = 50miles[/tex]
option A
Answer:
B. 60 miles
Step-by-step explanation:
A particle travels along the x-axis such that its position at time t is given by the function x(t) = 2€ + t. What is the average
speed of this particle over the interval 2 sts 10?
4
25
32
200
Answer:
See Explanation
Step-by-step explanation:
Given
The function is not clear, so I will use:
[tex]x(t) = 2+ 3t + t^2[/tex]
Required
Speed over 2 to 10s
This is calculated as:
[tex]Speed = \frac{x(a) - x(b)}{a - b}[/tex]
Where
[tex](a,b) =(2,10)[/tex]
So, we have:
[tex]Speed = \frac{x(2) - x(10)}{2 - 10}[/tex]
[tex]Speed = \frac{x(2) - x(10)}{-8}[/tex]
Calculate x(2) and x(10)
[tex]x(2) = 2+ 3*2 + 2^2 =12[/tex]
[tex]x(10) = 2+ 3*10 + 10^2 =132[/tex]
So, we have:
[tex]Speed = \frac{12 - 132}{-8}[/tex]
[tex]Speed = \frac{-120}{-8}[/tex]
[tex]Speed = 15[/tex]
From a horizontal distance of 80 m, the angle of elevation to the top of a flagpole is 18 degree. Calculate the height of the flagpole to the nearest whole meter.
Answer:
26m
Step-by-step explanation:
The value of the opposite side (height of the flagpole) is to be determined given the angle and the value of the adjacent side(horizontal distance )
We would use tan 18 to determine the value of the missing side
tan 18 = opposite / adjacent
0.3249 = opposite / 80
0.3249 x 80 = 26m

X°, y° and z °are three angles lying on a straight line having vertices at same point. If y° =45° and z °=86°. Find the value of x.
Answer:
49degrees
Step-by-step explanation:
The sum of angle on a straight line is 180degrees, hence;
x + y + z = 180
x + 45 + 86 = 180
x + 131 = 180
x = 180 - 131
x = 49degrees
Hence the value of x is 49degrees
Solve the inequality 4(x – 3) – 7 < 2(x – 3).
Answer:
{x}\lt\frac{{13}}{{2}}
Step-by-step explanation:
Answer:
x < 13/2
Step-by-step explanation:
4(x-3) -7: 4x - 19
4x - 19 < 2x-6
4x - 19 + 19 < 2x - 6 + 19
4x < 2x + 13
4x - 2x < 2x + 13 - 2x
2x < 13
2x/2 < 13/2
x < 13/2
The highest common factor of 10 and 18
Answer:
The highest common factor of 10 and 18 is 2
Step-by-step explanation:
10: 1,10,2,5
18: 1,18,2,9,3,6,
Look which is common in both of these and both of them have 2 in common.
The HCF of 10 and 18 is 2.
To find the highest common factor (HCF) of 10 and 18, we can determine the largest number that divides evenly into both of them.
We can start by listing the factors of each number:
Factors of 10: 1, 2, 5, 10
Factors of 18: 1, 2, 3, 6, 9, 18
From the lists, we can see that the common factors of 10 and 18 are 1 and 2.
To find the HCF, we select the largest common factor, which is 2. Therefore, the HCF of 10 and 18 is 2.
The HCF represents the largest number that divides evenly into both given numbers, without leaving any remainder. In this case, 2 is the highest common factor, as it is the largest number that can divide both 10 and 18 without leaving any remainder.

Solve by using substitution
y=2x
3x-y=3
answer:
x = 3
y = 6
step-by-step explanation:
we have two equations —y = 2x
3x - y = 3
we have to use substitution so we will replace y with 2x since y = 2x3x - 2x = 3
now that we have like terms, we can solve this to find x3x - 2x = 3
x = 3
now, we will use this to find yy = 2x
y = 2(3)
y = 6

Step-by-step explanation:
Sum of the ratio = 8
Total amount - 7200
[tex]Jay's\ share = \frac{1}{8} \times 7200 = 900\\\\Sheila's \ share = \frac{2}{8} \times 7200 = 2 \times 900 = 1800\\\\Harry 's \ share = \frac{5}{8} \times 7200 = 5 \times 900 = 4500[/tex]
Determine the approximate area of trapezoid
Answer:
25 squared cm
Step-by-step explanation:
Use the formula A = [tex]\frac{1}{2}[/tex]h ([tex]b_{1} + b_{2}[/tex])
h = height
[tex]b_{1}[/tex] = base 1
[tex]b_{2}[/tex] = base 2
A = [tex]\frac{1}{2}[/tex] (5) (7.2 + 2.8)
A = 25

Delia flew 2,416 miles the first year on the job. She flew 3,719 miles the second year. Delia flew 2,076 more miles the third year than the first and second years combined. How many miles did Delia fly the third year?
Answer:
8211 miles
Step-by-step explanation:
Delia flew 2416 miles on the first year of the job
She flew 3719 miles on the second year of the job
She flew 2076 miles more than the first and second year combined on the third year
= 2416+3719
= 6135
= 6135+2076
= 8211
Hence Delia flew 8211 miles on the third year
In the Tide Pool tank at the Atlantic Aquarium, there are 10 crustaceans and 25 fish. The Deep Blue tank has the same ratio of crustaceans to fish. There are 50 crustaceans in the Deep Blue tank.
How many fish are in the Deep Blue tank?
Answer:
It would be 125 fish.
Step-by-step explanation:
This is because since there are 10 crustaceans for every 25 fish, there are 2.5 times more fish than crustaceans. Therefore, if there were 50 crustaceans, you would do 50 * 2.5 to get 125 fish.

x=y-8 7x+2y=16 what is the answer???
Answer:
x = 0 , y = 8
Step-by-step explanation:
x = y - 8 -----(1)
7x + 2y = 16 --------(2)
Substitute (1) in (2)
7(y - 8) + 2y = 16
7y - 56 + 2y = 16
9y = 72
y = 8
Substitute y in (1)
x = 8 - 8 = 0
Find sec 0, sin 0, and tan 0, where is the angle shown in the figure.
Give exact values, not decimal approximations.
Answer:
Secθ = 11 / 9.22 or sec33°
Sinθ = 6 / 11 or Sin33°
Tanθ = 6 / 9.22 or Tan33°
θ = 33°
Step-by-step explanation:
Given:
Hypotenuse = 11 unit
Perpendicular = 6 unit
Find:
Secθ
Sinθ
Tanθ
Computation:
Base = √Hypotenuse² - Perpendicular²
Base = √11² - 6²
Base = √121 - 36
Base = √85
Base = 9.22 unit (Approx.)
Secθ = Hypotenuse / Base
Secθ = 11 / 9.22 or sec33°
Sinθ = Perpendicular / Hypotenuse
Sinθ = 6 / 11 or Sin33°
Tanθ = Perpendicular / Base
Tanθ = 6 / 9.22 or Tan33°
So value of θ = 33°

5. Find the area of the composite figure *
Answer:
187.5 ft²
Step-by-step explanation:
15 x 15 = 225
1/2(5 x 15) = 37.5
225 - 37.5 = 187.5
Answer:
the area is 187.5
Step-by-step explanation:
First we must split this figure into two, now we have a triangle on top of a rectangle (we know this is a rectangle because the length is longer than the width)
to find the area of a rectangle we must use the equation l*w=A so
15*10=150
Now that we have the area of the rectangle we must find the area of the triangle
We can see one side is longer, this shows us that the triangle is 5 units tall and 15 units long
the formula to find the area of a right triangle is ab/2=A
5*15/2=A
75/2=A
37.5=A
now we have both areas we add them together
37.5+150=187.5
187.5 is your answer

Answer:
110degrees
Step-by-step explanation:
Complete question
Q4: If x and y are two supplementary angles whereas m<x=70 then find the m<y.
The sum of two supplementary angles is 180degrees, hence;
m<x + m<y = 180
70 + m<y = 180
m<y = 180 - 70
m<y = 110degrees
Hence the measure of ,=m<y is 110degrees
