John is gliding along on his scooter at a speed of 2.8 m/s when
suddenly he collides with Sam who is walking around the corner. If
John is brought to rest in 0.15 s, what is his acceleration?
Answer:
18.67 m/s²
Step-by-step explanation:
a = ∆v/ t
a= v - u/t
a = 2.8 - 0 / 0.15
a = 2.8 / 0.15
a = 18.67 m/s²
Solve the following expression. d=5 2d+4d-9-7
Answer:
14Step-by-step explanation:
[tex]2d+4d-9-7\\\\d =5[/tex]
Substitute ; d= 5 into the given equation
[tex]2(5)+4(5) -9-7\\\\Follow\:the\:PEMDAS\:order\:of\:operations\\\\10 +20 -9-7\\\\\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:\:\\\\10+20 =30\\\\=30-9-7\\\\30-9=21\\\\=21-7\\\\21-7\\=14[/tex]
The value of the expression 2d + 4d - 9 - 7 is 14 if the value of d is 5 after plugging d = 5 in the equation.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
The expression:
= 2d + 4d - 9 - 7
Plug d = 5 in the above expression:
= 2(5) + 4(5)- 9 - 7
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
= 10 + 20 - 9 -7
= 30 - 16
= 14
Thus, the value of the expression 2d + 4d - 9 - 7 is 14 if the value of d is 5 after plugging d = 5 in the equation.

Please help me with this is so important
Step-by-step explanation:
78 + 119 + 105 + (180 - x) = 360
482 - x = 360
482 - 360 = x
122 = x
x = 122°
Answer:
it is trapezium and all angles value is 360 degree and three angles values are given then let unknown angle be y and add three angles then subtract value from 360 degree then add the value with x and subtract that value from 180 degree

Evaluate
(7.3 X 10^6) + (2.4 X 10^7)
(4 X 10^4)
Answer:
Step-by-step explanation:
(7.3 X 10^6) + (2.4 X 10^7)
= 31.3 × 10^6
or 3.13 × 10^7
(4 X 10^4)/ (31.3×10^7)
=1.28 × 10^-3
y+7=-2/3(x+6) as a linear function
It says to solve for z, but don’t know how to.
Z-7x(-2)=-6
Answer:
z = - 6 - 14x
Step-by-step explanation:
Given
z - 7x(- 2) = - 6 , that is
z + 14x = - 6 ( subtract 14x from both sides )
z = - 6 - 14x

Step-by-step explanation:
I'VE ASKED THIS ONE EARLIER BUT NOBODY ANSWERED Point D is in the interior of \small \angle ABC, \small m\angle ABC=20x-15, \small m\angle ABD=6x-5, and \small m\angle DBC=x+16. What is \small m\angle ABD? \small m\angle ABD= degrees
Answer:
7°
Step-by-step explanation:
Since, Point D is in the interior of angle ABC.
Therefore,
[tex]m\angle ABC = m\angle ABD + m\angle DBC\\
20x - 15 = 6x - 5 + x + 16\\
20x - 15 = 7x + 11\\
20x - 7x = 11+15\\
13x = 26 \\ x = \frac{26}{13} \\ x = 2 \\ \\ m\angle ABD = (6x - 5) \degree \\ m\angle ABD = (6 \times 2 - 5) \degree\\ m\angle ABD = (12 - 5) \degree \\ \huge \red{ \boxed{ m\angle ABD = 7\degree}}[/tex]
find the zero of the function f(x) =-3x + 1
To find the zero of a function, we have to set f(x) equal to 0
0 = -3x + 1
Subtract 1 from both sides.
-1 = -3x
Divide both sides by -3
1/3 = x

Draw a 1 by 4 rectangle.
Underneath it draw a 2 by 2 rectangle.
They both have the same area (4 units) but they are not congruent. The corresponding lengths are not equal and that is another condition that must be met for there to be congruence. There are many others.
Draw a 2 by 2 square.
draw a triangle with a base of 1 and a height of 8. These two figures have the same area, but they don't even have the same number of sides.
C is simply not true.

What happens to the copy when it is created with a scale factor greater than 1? Less than
1? Exactly 1?
Answer:
When a figure is scaled by a scale factor greater than 1, the copy is larger than the original. When the scale factor is less than 1, the copy is smaller. This means that triangles and are scaled copies of each other.

You want to leave a nice tip on a $36 meal. So you decide to add 20% to the bill. How much is the total bill?
Answer:
43.20
Step-by-step explanation:
First find the tip
36 * 20 %
36 * .2
7.20
Then add the tip to the amount of the meal
36+7.20
43.20
You went to have a meal which costs $36, and maybe becoming very delighted with the taste and service of the food centre, you decided to add a tip.
[tex]20\%[/tex] of the total meal.So, First we need to find the tip by multiplying the percentage with the cost of meal
Tip:
[tex]20\% \: of \: 36[/tex]
[tex] \frac{20}{100} \times 36[/tex]
[tex] \frac{1}{5} \times 36[/tex]
[tex]7.2[/tex]
Now, we have got the amount of money we decided to give as a tip. And, we are already having the cost of meal. So, total money paid:
[tex]36 + 7.2[/tex]
[tex] \boxed{ 43.2}[/tex]
This is our required answer.

1/3(1 - 1/4) to the second power?
Answer:
0.1875
Step-by-step explanation:
Iola has $75. She buys a pair of shoes on sale for one-half off and a pair of socks for $6. She has $32 left. Which equation can be used to find x, the regular price of the shoes?
Answer:
To solve for the problem above, let x be the regular price of the shoe.
1/2x is the one-half price of the shoe then we add 6 for the pair of socks,
1/2x + 6, then lola has 32 left so we add that too, 1/2x + 6 + 32 = 75. The total amount of lola spent is 75 - 32, which is 1/2x + 6.

Choose 1 answer:
Add/subtract the same quantity to/from both sides
B
Add/subtract a quantity to/from only one side
Rewrite one side (or both) by combining like terms
Rewrite one side (or both) using the distributive property
Answer:
Step-by-step explanation:
C
Rewrite one side (or both) by combining like terms which is option(C)
What is equation?Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.
2x – 1 + 3x = 0
5x – 1 = 0
To get Equation B from A, we would rewrite one side (or both) by combining like terms
2x – 1 + 3x = 0
5x – 1 = 0
This is Equation B
