Answer:
3 m/s / 10.714 km/hr
Step-by-step explanation:
15m/5s
3m/1s
3m ÷ 1000 = 0.003 km
1s ÷ 3600 = 0.00028 hr
0.003 km/ 0.00028 hr
=10.714 km/hr approx.
A chef uses 2 3 cup of flour for every 1 8 cup of water in a dough recipe. If the chef follows the recipe proportions, which statement is true?
Step-by-step explanation:
A chef uses 2/3 cup of flour for every 1/8 cup of water in a dough recipe.
It means,
2/3 cup = 1/8 cup of water
[tex]1\ \text{cup}=\dfrac{\dfrac{1}{8}}{\dfrac{2}{3}}\\\\=0.1875[/tex]
Hence, the constant of proportionality is 0.1875.
The sum of the lengths of the two bases of a trapezoid is 22 cm and its area is 66 cm2.
What is the height of the trapezoid
Answer:
h = 6 cm
Step-by-step explanation:
Given that,
The area of a trapezoid, A = 66 cm²
The sum of the lengths of the two bases of a trapezoid is 22 cm.
We need to find the height of the trapezoid.
The area of a trapezium is given by :
[tex]A=\dfrac{1}{2}\times (\text{sum of parallel sides})\times \text{height}[/tex]
Substitute the values,
[tex]h=\dfrac{2A}{\text{sum of parallel sides}}\\\\h=\dfrac{2\times 66}{22}\\\\h=6\ cm[/tex]
So, the height of the trapezoid 6 cm.

Answer:
a=21°b=70°c=89°
Step-by-step explanation:
a=21°[by vertical opposite angle]
b+110°=180°[by linear angle]
b=180°-110°=70°
a+b+c=180°[by sum of all angle]
21°+70°+c=180
91°+c=180°
c=180°- 91°
c=89°
To find the sizes of angles a, b, and c, we need to use the properties of straight lines and angles. Since angles on a straight line add up to 180 degrees, we have: Angle a = 21°, Angle b = 159°, Angle c = 159°
Angle b: We know that the sum of angles on a straight line is 180°. Angle b and angle a are on a straight line, so we can write the equation:
b + a = 180°
Given that angle a is 21°, we can now solve for angle b:
b + 21° = 180°
b = 180° - 21°
b = 159°
Angle c: Angles b and c are vertically opposite angles, which means they are equal in measure. So, we have:
c = 159°
Angle a: We already know the measure of angle a:
a = 21°

1.8 divide by 0.72 explain
Answer:
0.40
Step-by-step explanation:
Change the divisor 1.8 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
7.2 ÷ 18 = 0.40
and therefore:
0.72 ÷ 1.8 = 0.40
Both calculated to 2 decimal places.

Answer:
268
Step-by-step explanation:
Answer:
The number that goes in the box is 268
Step-by-step explanation:
Equations
We are given an incomplete identity:
___ + 308 - 126 = 450
And it's required to fill the space with the number that makes the identity true.
Let's fill the space with a variable x:
x + 308 - 126 = 450
Solving for x implies doing inverse operations as shown on the left side.
We must add 126 and subtract 308:
x = 450 + 126 - 308
x = 268
The number that goes in the box is 268
Ritu and Jitu both deposited Rs 100 in a Bank. Ritu deposited for 5 years with interest rate 8% per year and Jitu deposited for 4 years with interest rate 9% per year. Who will get more interest? By how much?
Step-by-step explanation:
Step 1
For Ritu,
Principal(P) = Rs 100
Time(T) = 5 year
Rate(R) =8%pa
Intrest (I) = ???
We know,
I = P*T*R /100
= 100*8*5/100
=Rs40
now
For Jitu,
Principal(P) =Rs 100
Rate(R)=9%pa
Time (T) = 4 year
Intrest(I) =?
We have
I = P*T*R/100
=100*4*9/100
=Rs36
Step 2
We have
Intrest of Ritu have more then that of Jitu so she makes more profit
now Profit diffrence =Rs40-Rs36
=Rs4
Therefore Ritu gets 4 more profit then Jitu

Evaluate the function g(x) = -2x2 + 3x - 5 for the input values -2, 0, and 3.
9(-2) = -2(-2)2 + 3(-2) – 5
9(-2) = -2(4) - 6 - 5
g(-2) =-19
g(0) =-5
g(3) =-14
Answer:
g(-2) = -19, g(0) = -5 and g(3) = -14
Step-by-step explanation:
The given function is :
[tex]g(x) = -2x^2 + 3x - 5[/tex] ...(1)
We need to find the function when x = -2,0 and 3.
Put x = -2 in equation (1).
[tex]g(-2) = -2(-2)^2 + 3(-2) - 5\\\\=-19[/tex]
Put x = 0 in equation (1).
[tex]g(0) = -2(0)^2 + 3(0) - 5\\\\=-5[/tex]
Put x = 3 in equation (1).
[tex]g(3) = -2(3)^2 + 3(3) - 5\\\\=-14[/tex]
Hence, g(-2) = -19, g(0) = -5 and g(3) = -14
