Answer:
555
Step-by-step explanation:
If each side of a square is 15 miles, we can find the total distance travelled by finding how many sides of squares were travelled.
You could either count the boxes, or, as I'm going to do, you could calculate the length of each straight line.
I switch between the y axis and the x axis, because we are travelling in different directions (if moving up/down we pay attention to y-axis, if moving right/left we pay attention to x-axis)
From 'Home' to the 'Restaurant', we are travelling from 6 to -7 on the grid. So, if we want to know the distance between them, we need to figure out how far apart they are. This is similar to figuring how far apart any two numbers are--we find the difference. (6) - (-7) [6 + 7] = 13. So, the amount of squares travelled from home to the restaurant is 13.
[I pay attention to the values along the x-axis for these two points because we are considering the distance along the x-axis]
[y-axis because it is vertical travel]
Restaurant (at -5) to campground (at 2) has a distance of : 7
[x-axis because it is horizontal travel]
Campground (at -7) to Rest Area (at -3) has a distance of : 4
[y-axis travel]
Rest Area (at 2) to the endpoint of that line segment (at 8) has a distance of: 6
[x-axis travel]
Endpoint of line segment (at -3) to endpoint below destination (at 3) has a distance of : 6
[y-axis travel]
Endpoint below destination (at 8) to destination (at 9) has a distance of : 1
We can then add all of the distance travelled:
13 + 7 + 4 + 6 + 6 + 1
= 37
37 sides of boxes were travelled, so we can multiply:
37 x 15
= 555
because each box length is 15 miles.
So, the family travelled 555 miles

Answer:

Step-by-step explanation:
-3(2t-1)=t+t+t+3 pls help
Answer:
t=0
Step-by-step explanation:
First, we expand everything. The left-hand side is -3(2t) - 1(-3), and we expand it to be -6t+3. The right-hand side is t+t+t+3, and we can reduce it to 3t+3. Now that we have both sides of the equation, we set them to each other.
-6t+3=3t+3 (subtract 3 on both sides)
-6t=3t (add 6t to both sides)
9t =0 (divide by 9)
t=0

hich represents the inverse of the function f(x) = 4x?
Oh(x)=x+4
Oh(x)=x-4
h(x) = ²x
h(x) = x
Answer:
[tex]h(x) = \frac{1}{4} x[/tex]
Step-by-step explanation:
To find the inverse of a function, the steps are:
Let y= f(x)Make x the subject of formulaReplace x with f⁻¹(x) and y with xIn this case, since h(x) is the inverse function of f(x), we can replace x with h(x) in step 3.
_____
f(x)= 4x
Let y= f(x) [tex]\textcolor{steelblue}{\text{ - step 1}}[/tex]
y= 4x
Divide both sides by 4:
[tex] \frac{1}{4} y = x[/tex]
[tex]x = \frac{1}{4} y \: \: \: \textcolor{steelblue}{\: \text{ - step 2}}[/tex]

What is the greatest common factor of 12, 2, and 84?
Answer:
2
Step-by-step explanation:
2 can go into 12,2, and 84
To obtain the greatest common divisor of (g.c.d) we must do it in simultaneous decomposition.
This method consists of extracting the common and uncommon prime factors, then

The triangle and the trapezoid have the same area what is the base b of the triangle
Answer:
b =22
Step-by-step explanation:
The formula to calculate the area of a trapezoid:
1/2*(a+b)*h : (a: base, b: base, h: height)
The formula to calculate the area of a triangle:
1/2*a*h (a: base, h: height)
All inputs are given for trapezoid so let's first find the area of trapezoid then we can find the value of b:
1/2*(10+12)*7 = 77 cm^2 is the area of trapezoid
now for the area of triangle:
1/2*b*7 = 77 (it was given that the areas are equal)
first we multiply both sides by 2
7*b = 154 now divide both sides by 7
b = 22

Answer:
a) k = 10 b) k = 7.5
Step-by-step explanation:
a)
( 5k+ 20 ) + ( 7k + 40 ) = 180
12k + 60 = 180
12k = 120
k = 10
b)40 + ( 12k + 10) + 180 - ( 8k + 80 ) = 180
50 + 12k + 180 - 8k - 80 = 180
50 + 12k -8k - 80 = 0
50 + 4k - 80 = 0
30 = 4k
k = 7.5
The sum of multiples of five from 10 to 75, inclusive.
The asked sum of multiples of five from 10 to 75, inclusive, is 595.
To find the sum of multiples of five from 10 to 75, inclusive, we can use the formula for the sum of an arithmetic series:
Sum = (n/2) * ([first term] + [last term])
Following the given case, the first term (a) is 10, the last term (l) is 75, and the common difference (d) between consecutive terms is 5 (since we are considering multiples of five).
The number of terms (n) can be calculated as:
n = (last term - first term) / common difference + 1
Let's calculate the number of terms first:
n = (75 - 10) / 5 + 1
n = 65 / 5 + 1
n = 13 + 1
n = 14
Now, we can determine the sum of the multiples of five:
Sum = (14/2) * (first term + last term)
Sum = 7 * (10 + 75)
Sum = 7 * 85
Sum = 595
Therefore, the asked sum of multiples of five from 10 to 75, inclusive, is 595.
