Answer:
This means that 1cm on the map means 10miles on actual land so is it the same for 30miles
That is 1cm on map 30 cm on land
Given: g(x) = 3x² + 2 and h(x) = 2x + 2
Find: g(h(x))
Step-by-step explanation:
g(x) = 3x² + 2
h(x) = 2x + 2
g(h(x)) = g([2x + 2]) = 3[2x+2]² + 2
= 3[4x² + 8x + 4] + 2
= 12x² + 24x + 12 + 2
= 12x²+ 24x + 14

Ms. G, Mr. Adams, and Ms. Leahman are going for a bike ride together on Saturday. They want to meet each other in the city but they all live in Bedstuy. Ms. G and Ms. Leahman have to bike 4 miles there, Mr. Adams is 5 miles away. They meet each other in the city and bike 2 miles together. Then they all return home the same way. How many miles did they all bike in total on Saturday?
Answer: 22 miles
Step-by-step explanation: Ms. G and Ms. Leahman both bike the same amount on Saturday:
4 miles to go to the city;
2 miles with Mr. Adams;
4 miles back to Bedstuy;
Then, both biked:
4 + 2 + 4 = 10 miles
Now, Mr. Adams bikes:
5 miles to go to the city;
2 miles together with the other two;
5 miles back to Bedstuy;
Then, he biked, in total:
5 + 2 + 5 = 12miles
So, the three of them biked, in total:
10 + 12 = 22
On Saturday, Ms. G, Mr. Adams and Ms. Leahman biked, in total, 22 miles.
. Find the distance between (−4,−1) and (−2,−3).
Answer:
2.83 units
(results are in decimal form, rounded to the nearest 100th)
Find the distance of the following points.
3. (0,2) (4, -1)
Hey there! I'm happy to help!
To find the distance between two points, you find the difference between the x values, square that, find the difference between the y values, square that, add the two numbers you got, and then find the square root.
We find the difference of the x values.
0-4=-4
Square it.
-4²=16
We find the difference between the y values.
2--1
2+1=3
And we square that.
3²=9
We add the two numbers we got.
16+9=25
And we find the square root.
√25=5
The distance between these points is 5. Now you can find the distance between any two points! Have a wonderful day! :D
What is the solution to this equation?
2x + 2 = 10
O A. x= 4
O B. x = 16
O c. x = 24
O D. x = 6
Answer:
A. x= 4
Step-by-step explanation:
[tex]2x + 2 = 10[/tex]
Collect like terms and simplify
[tex]2x =10-2\\2x =8[/tex]
Divide both sides of the equation by 2
[tex]\frac{2x}{2} = \frac{8}{2} \\\\x = 4[/tex]
this is equivalent? TRUE OR FALSE.
Step-by-step explanation:
yes of course...
just like
saying 2=x is equivalent to x=2
similarly x<3 is equivalent to 3>x

En el colegio de Pedro 8/25 de los cursos corresponden a la enseñanza media y el resto a basica. ¿Que numero representan los cursos de enseñanza básica?
Answer:
17
Step-by-step explanation:
Hay dos cursos que se ofrecen en la escuela y se representan como fracciones.
Cursos corresponden a la enseñanza media = 8/25
Cursos de enseñanza básica =?
Sea el número total de cursos = 1
Cursos de enseñanza básica = 1 - 8/25
= 17/25
Dado que ambos cursos están en forma de fracciones, podemos convertirlos en razones
Relación de cursos corresponden a la enseñanza media a cursos de enseñanza básica
= 8:17
Donde el número total de cursos ofrecidos = 8 + 17 = 25
Por lo tanto, el número que representa los cursos de enseñanza básica = 17.
Find the midpoint of the line segment joining the two points.
(1.8, -3.4) and (-0.4, 1.4)
Answer:
(0.7, -1)
Step-by-step explanation:
To find the coordinates for the midpoint you add each coordinate together and divide by 2.
M = ([tex]\frac{1.8 - 0.4}{2}, \frac{-3.4 + 1.4}{2}[/tex])
M = [tex](\frac{1.4}{2}, \frac{-2}{2})[/tex]
M = (0.7, -1)

One of the two equal factors of a number is
Answer:
If the two factors are equal (the same), like 4*4=16, then each of them is called a "square root." Note: a cube root is one of three equal factors of a number, for example, 2 is the cube root of 8 (that is, 2*2*2=8).

A T-shirt shop charges $15 for an adult shirt and $12 for a youth shirt. The total charge for a shirt order was $489.
Which equation can be used to represent x, the number of adult shirts sold and y, the number of youth shirts sold?
12x + 15y = 489
27x + 15y = 489
15x + 12y = 489
15x + 3y = 489
Answer: C. 15x + 12y = 489
Step-by-step explanation: Got it right on edge test

Duval scored 10 more than 2 times the number of points scored by a
player, x. Which equation shows the number of points, y, Duval scored?
Answer:
2x + 10 = y
Step-by-step explanation:
The term 10 more is plus 10, and 2 times the "number" which we know we can label as "x". 2x + 10 is the equation and we are told that y is the number of points so 2x + 10 = y is the answer.
Hope that helps, and have a great day!
k/7 = 10 solve for k
Answer:
k=70
Step-by-step explanation:
to get k by itself you need to multiply k/7 by 7, and you multiply on both sides. 10 times 7 =70
Answer:
Step-by-step explanation:
k/7 = 10
or, k = 7*10
Therefore, k=70.
The quotient of six and the sum of a number and eight
Answer:
6
——
x+8
Step-by-step explanation:
The quotient of six (6) and the sum of a number and eight (8) is equal to [tex]\frac{x + 8}{6}[/tex]
Let the unknown number be x.
In Mathematics, quotient simply means to divide a number by another number without any remainder.
Translating the word problem into an algebraic expression, we have;
The sum of a number and eight = [tex]x + 8[/tex]
Quotient of six (6) and the sum of a number and eight (8) is equal to;
[tex]\frac{x + 8}{6}[/tex]
In conclusion, the quotient of six (6) and the sum of a number and eight (8) is equal to [tex]\frac{x + 8}{6}[/tex]

We can see that the diagonal distance from the fire pit to the tree is 6 units, if you count, with a slope of 1, meaning that we only have to stay on that diagonal.
A third of 6 is 2, so we'll just go 2 units in that diagonal, putting us at the point [tex](4,3)[/tex].
Hope this helps.
