Answer:
5 m
Step-by-step explanation:
A model car is made to a scale of 1:50 (model: real).
If the model has a length of 10 cm, calculate the length of the real car (answer in meters).
We have a scale of :
model: real = 1:50
The model has a length of 10cm
Hence:
1 cm = 50 cm
10 cm = x cm
Cross Multiply
x cm × 1cm = 10 cm × 50 cm
x cm = 10 cm × 50 cm/1cm
x cm = 500 cm
The length of the real car is 500cm
Converting the length of the real car to meters
100cm = 1 m
500 cm = x m
Cross Multiply
100cm × x m = 500 cm × 1 m
x m = 500 cm × 1 m/100 cm
x m = 5 m
The Length of the real car in meters is 5m

Answer:
x = 13
Step-by-step explanation:

ayudenme plis
Answer:
a. Velocidad = 16 m/s
b. Deceleración = 0.64 m/s²
Step-by-step explanation:
Dados los siguientes datos;
Tiempo = 25 segundos
Distancia = 400 metros.
a. Para encontrar la velocidad;
Velocidad = distancia/tiempo
Velocidad = 400/25
Velocidad = 16 m/s
b. Para encontrar la desaceleración;
Durante una desaceleración, la velocidad inicial es mayor que la velocidad final.
Deceleración = (v - u)/t
Sabemos que la velocidad final es igual a cero (0) porque el automóvil se detiene.
Deceleración = (0-16)/25
Deceleración = 16/25
Deceleración = 0.64 m/s²
Andy wants to buy a used car that cost $8,500. He has
saved $1,300 and can save an additional $225 each month.
How many months will it take for Andy to have enough
money for the car?
Answer:
32 months.
Step-by-step explanation:
Andy wants a car that costs $8,500.
He already saved $1,300.
$8500 - $1300 = $7200
Andy can save an additional $255 each month.
7200 ÷ 255 = 32
So, it would take Andy 32 months to have enough money to buy the car.
A fourth grade teacher gives homework every night in both mathematics and language arts. The time to complete the mathematics homework has a mean of 10 minutes and a standard deviation of 3 minutes. The time to complete the language arts assignment has a mean of 12 minutes and a standard deviation of 4 minutes. The time to complete the mathematics and the time to complete the language arts homework has a correlation rho = -0.75. The variance of the time to complete the entire homework assignment is
Answer:
4
Step-by-step explanation:
Given that:
X = time taken to complete mathematics homework
Y= time taken to complete language homework
Standard deviation of X ; SD(X) = 3
Standard deviation of Y ; SD(Y) = 4
rho = - 0.375
rho = Cov(X, Y) / SD(X) * SD(Y)
-0.375 = COV(X, Y) / 3 * 4
COV(X, Y) = 12 * - 0.375
COV(X,Y) = - 4.5
Variance(X, Y) = V(X, Y)
V(X, Y) = V(X) + V(Y) + 2COV(X,Y)
V(X) =SD(X)² = 3² = 9
V(Y) = SD(Y)² = 4² = 16
V(X,Y) = 9 + 16 + 2(-4.5)
V(X, Y) = 16
SD(X, Y) = sqrt(V(X, Y)) = sqrt(16) = 4
Hence, standard deviation to complete entire homework, SD(X, Y) = 4
.. What is the value of this expression? 6 + (-9) - (-5) i need help on my test can u guys help me and no links because the links u guys give me dont work(no disrespect)
Answer:
-8
Step-by-step explanation:
What is the value of this expression? 6 + (-9) - (-5)
6 + (-9) - (-5)
= 6 - 9 + 5
Following the rules of BODMAS, addition comes first before subtraction
= 6 - 14
= - 8
6 + (-9) - (-5) = -8
Note:
- * - = +
- * + = -
+ * - = -
+ * + = +
Then using BODMAS
B - bracket

Which statement is true about the equation in the box?
x + 9 - 4x = -3x - 3
A. There is only 1 solution, and x = -3.
B. There is only 1 solution, and x = 9.
C. There are infinitely many solutions because the variables cancel each other.
D. There is no solution because 9 ≠ -3.
Answer:
D. There is no solution because 9 ≠ -3.
Step-by-step explanation:
For finding out the statement let's check it ourselves
x + 9 - 4x = - 3x - 3
-3x + 9 = - 3x - 3
9 ≠ - 3
So there is no solution for the equation.

Find the additive inverse of 3x−6
Answer:
3x+6
Step-by-step explanation:
inverse means the opposite of the sign and the opposite of subtraction is addition so I used addition
The additive inverse of 3x − 6 is -3x + 6
What is additive inverse?
The additive inverse of a number x is a number that when added to x gives a result of 0.
For the expression 3x - 6
The additive inverse is a number that can be added to the expression to get 0. Hence:
The additive inverse of 3x − 6 is -3x + 6

What is the green dashed line called?
Answer:
The line (or "axis") of symmetry is the y-axis, also known as the line x = 0. This line is marked green in the picture. The graph is said to be "symmetric about the y-axis", and this line of symmetry is also called the "axis of symmetry" for the parabola.
The equation of the function g(x), after the translation, is given as follows: g(x) = (x + 2)² + 4.
What is a translation?A translation happens when either a figure or a function are moved horizontally or vertically.
The four translation rules for functions are given as follows:
Left a units: f(x + a).
Right a units: f(x - a).
Up a units: f(x) + a.
Down a units: f(x) - a.
The parent function for this problem is given as follows:
f(x) = x².
For this problem, the parent function was moved:
2 units left, hence g(x) = f(x + 2).
4 units up, hence g(x) = f(x + 2) + 4.
Hence the function g(x) is defined as follows:
g(x) = (x + 2)² + 4.

Given ΔABC ≅ ΔDEF. Determine the measure of angle C.
A) 33 degrees
B) 55 degrees
C) 88 degrees
D) 92 degrees
Answer:
A) 33 degrees
Step-by-step explanation:
Since both triangles are congruent, the corresponding angles are congruent, as well. Angle C and Angle F are corresponding angles (meaning that they are the same angle on two different triangles), so their angle measures are congruent. Angle F is 33 degrees, so Angle C is 33 degrees.

A straight road to the top of a hill is 2500 feet long and makes an angle of 12 degrees with the horizontal. Find the height of the hill.
Answer:
519.8 feet
Step-by-step explanation:
A straight road to the top of a hill is 2500 feet long and makes an angle of 12 degrees with the horizontal. Find the height of the hill.
We solve this question using the Trigonometric function of Sine
sin theta = Opposite/ Hypotenuse
Theta = 12°
Hypotenuse = 2500 feet
Opposite = Height of the hill = x
Hence,
sin 12 = x/ 2500 feet
Cross Multiply
x = sin 12 × 2500 feet
x = 519.77922704 feet
Approximately = 519.8 feet
The height of the hill is 519.8 feet

Given this set of data: 132 127 106 140 158 135 129 138 What are the lower outlier limit and the upper outlier limit ? Answers separated by a comma and a space. Ex. 11, 179 * 1 point
Answer:
(111.5, 155.5)
Step-by-step explanation:
Given the data:
132 127 106 140 158 135 129 138
The Outlier formula :
Lower = Q1 - 1.5(IQR)
Higher = Q3 + 1.5(IQR)
Using a calculator :
Q1 = 128
Median, Q2 = 133.5
Q3 = 139
IQR = Q3 - Q1 = 139 - 128 = 11
Lower = Q1 - 1.5(IQR) = 128 - 1.5(11) = 111.5
Higher = Q3 + 1.5(IQR) = 139 + 1.5(11) = 155.5
(111.5, 155.5)

A. c = 3d
B. d = 3c
C. c = d + 3
D. c = d + 3d
Answer: A. c = 3d
I'm gonna go with c = 3d
Step-by-step explanation: c = 3d
After looking at the table I believe the equation would be c=3d. I came to this conclusion because (6)=3(2); (9)=3(3); (15)=3(5); 18=3(6). I really hope this helps!:)

Veronika works as a cook at Toyem Catering, she makes $58,200/year. She pays 18% in taxes and $125/month for health insurance. What is Veronika's net income per month?
a
$4,200
b
$3,852
c
$4,850
d
$2,989
Veronika's net income per month is $3,852. Option B
How to calculate Veronika's net income per monthThe annual amount of taxes that Veronika pays:
Annual taxes = 0.18 x $58,200 = $10,476
Annual health insurance = $125/month x 12 months = $1,500
we can calculate Veronika's net annual income by subtracting the taxes and health insurance from her annual salary:
Net annual income = $58,200 - $10,476 - $1,500 = $46,224
We can calculate her net income per month by dividing her net annual income by 12:
Net monthly income = $46,224/12 = $3,852
