Answer:
a) 225 meters
b) -162°C
Step-by-step explanation:
a) 5 meters per second for 45 seconds. 5*45 = 225 meters
b) cooled by 18°C per hour over a 9 hour period. -18*9 = -162°C
Answer:
a) 225 meters.
B) -2 °
Step-by-step explanation:
a If it is moving 5 meters per second, then in one second it moves 5 meters, in 2 seconds it move 10 meters, in 3 seconds it move 15 minters.
So to find how much it moved in 454 seconds we would multiply 45 x 5 = 225
B) In 9 hours it cooled 18 degrees 18/9 = 2. This means that is cooled 2 degrees per hour.

Determine the number of quarters and the number of nickels that Isaac has.
By using the method subtraction,
1 quarter is 0.25
1 nickel is 0.05
What is subtraction?To subtract in mathematics is to take something away from a group or a number of objects. The group's total number of items decreases or becomes lower when we subtract from it. The components of a subtraction issue are the minuend, subtrahend, and difference. An arithmetic operation called subtraction simulates the process of deleting items from a collection. The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.
Given that,
Isaac has 18 coins, all quarters and nickels.
The total value of the coins it $3.50.
Let the quarters be x and nickels be y
x+ y= 18
x= 18 - y... equation 1
1 quarter is 0.25
1 nickel is 0.05
So,
0.25x+ 0.05y= 3.50
substitute x value in above equation
0.25(18-y)+0.05 = 3.50
4.5-0.25y+ 0.05 = 3.50
4.55 - 3.50 = 0.25y
1.05= 0.25y
y= 4.2
y in equation 1
x= 18 - y
x= 18-4.2
x= 13.8

We have to find the angle marked t.
Let us name the triangle.
Let the vertex formed by the intersection of two equal sides be A and,
The vertex with 30 degree angle be B and the third vertex be C.
We know that,
AB = AC
Hence,
∠ ABC = ∠ ACB = 30 degrees.
Hence, ∠ BAC = 180 - 30 - 30 = 120 degrees
We know that,
t + ∠ BAC = 180 degrees (supplementary angles)
Hence,

PLEASE HELP I AM GROUNDED AND MY MOM IS FURIOUS WITH MY GRADE
Answer:
p = 11, I hope this helps and I hope you can improve your grade.
Step-by-step explanation:
Adjacent Angles = 90 degrees, or a right angle.
90 = (5p + 7) + (3p - 5)
1. Subtract the numbers
90 = 5p + 2 + 3p
2. Combine Like Terms
90 = 5p + 2 + 3p
90 = 8p + 2
3. Subtract 2 from both sides
90 - 2 = 8p + 2 - 2
88 = 8p
4. Divided 8 from both sides
88/8 = 8p/8
p = 11

The zurn family ate at a restaurant that was having 15% discount on that day .Their meal costs 64.75,and they left a 20% tip .What is the total cost of the meal? (Note: the tip applies to the total cost of the meal before the discount was applied)
The total cost of the meal is 66.045
Given,
The cost of the meal = 64.75
The discount given on that day = 15%
The tip given by Zurn family = 20%
We have to find the total cost of the meal.
First we have to find the total cost including tip before discount is added.
That is,
120% of 64.75
= 64.75 × 120/100
= 6.475 × 12
= 77.7
Here, the total cost including tips before discount is 77.7
Now, we have to deduct the discount.
100 - 15 = 85
That is,
85% of 77.7 will be the total cost of the meal
= 77.7 × 85/100
= 6604.5 / 100
= 66.045

Two values of v satisfy the equation |2v- 13| +6 = 9. What is the sum of these values?
Answer: v = 8, 5; The sum of these values would be 13.
∣2v − 13∣ + 6 = 9
Combine like terms, utilizing the properties of equality. Do not forget to follow the order of operations!
∣2v − 13∣ + 6 = 9
Subtract 6 from both sides of the equation.
∣2v − 13∣ = 3
Consider the definition of absolute value (distance from the number zero); the absolute value of x and -x would both be x.
2v − 13 = 3
2v − 13 = −3
Add 13 to both sides of the equation.
2v = 16
2v = 10
Divide both sides of the equation by 2.
v = 8
v = 5
Add the sum of the values.
8 + 5 = 13
Urgent | Find the angles of the following shape
Step-by-step explanation:
easy so first you are going to subtract 130 from 180 since any angle that is made on a straight line segment if subtracted you get the answer of the other angle
180-130 =50
I want you to draw this diagram on paper and extend the line S that is 50° since we know the angle SRQ =130
Now you will be able to see a Z formation PQR and the other half of the S is making a Z formation the interior angles of a z formation are always equal to each other
so the interior x =50°
extend the line P or Q out wards that will also be equal to the other side now since it also makes a Z formation
As we know that the angle SRQ is equal 130 we will half it or divide it by 2 the answer will be 65
one angle in R angle will be 65 while the other one will also be 65
Now we know two angles in the triangle PQR and one angle in triangle PRS
applay the formula that all interior angles sum =189
x + 65 + z =180 (name the left unknown angle z)
50 + 65 + z= 180
105+ z =180
z=180-105
z=75
we now all the angles in the triangle x
y angle =65 again apply the z formation to get the answer

Just answer questions 12 and 13 !
Answer:
Step-by-step explanation:
12. We have : angle ABF = angle ABE + angle FBE = 2(w+11) + angle FBE = 8w - 6
-> angle ABE = 8w - 6 - [2(w+11)] = 8w - 6 - 2w - 22 = 6w - 28.
13. As we can see, angle EBA and angle EBC is a linear pair, therefore they're supplementary angles, adding up to 180.
-> 3r + 10 + 2r - 20 = 180
5r - 10 = 180
r = 38.
So, angle EBF = 2r - 20 = 76 - 20 = 56.
