Answer:
45/10 =4.5
4.5 x 7 = 31.5
Hight = 31.5
Answer:
B.
Step-by-step explanation:
Since they are equal do.
45 divided by 10
which equals 4.5.
So the image is being reflected by a 4.5 times bigger scale.
So then you do,
7 x 4.5
which is 31.5.
what is the sum of the interior angles of a hexagon?
Hello!
So, every interior angle of a regular hexagon measures 120 degrees.
There are six interior angles of a hexagon, so you have to multiply 120 by 6.
120 x 6 = 720
So, the answer to your question is that the sum of the interior angles of a hexagon is 720 degrees.
Hope this helps!

A construction team is going to Guatemala to help a missionary build a church building. The construction team will be there for 24 days, which is 50% more days than they need to complete construction. How many days will they need to complete the church building
Answer:

50% means ½ of the usual days,
if 50% = 24 days
then the usual day is 48 days
so, 48+24= 72

If it costs a total of $9 to buy 1 hot dog and 2 bottles of water and it costs a total of $22 to buy 3 hot dogs and 4
bottles of water, how much does a single bottle of water cost?
Answer:
$2.50
Step-by-step explanation:
1h + 2w = 9
3h + 4w = 22
Multiply the first expression x 3
3h + 6w = 27
Subtract the 2 equations
3h + 6w = 27
3h + 4w = 22
2w = 5, w = 2.5

16 liters to fraction
Answer:
16 liters to a fraction would be 4.2 or 4 1/5
Step-by-step explanation:
16 liters = 4.22675 gallons
4.2 gallons = 4 1/5 gallons
1000 L= 1 KL
16 L = 0.016 KL
(Divide 16 by 1000 to convert.)
If the magnitude of vector u is ||u||=7.81 and its angle of direction is 129.81°, which graph represents vector -u?
Answer:
see attached
Step-by-step explanation:
The vector -u will be in the opposite direction of u. The magnitude is 7.81, but the angle is 129.81° -180° = -50.19°. A graph of it is attached.
_____
The (x, y) components are ...
7.81(cos(-50.19°), sin(-50.19°)) ≈ (-5.00, -6.00)
Teresa will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $59 and costs an additional $0.08 per mile driven, The second plan has an initial fee of $48 and costs an additional $0.10 per mile driven. For what amount of driving do the two plans cost the same? Omiles What is the cost when the two plans cost the same? $0
Answer:
1. 550 miles
2. $103
Step-by-step explanation:
y = total rental cost
m = initial fee
x = cost per mile
n = number of miles
Plan 1: y = m + xn = 59 + 0.08n
Plan 2: y = m +xn = 48 + 0.10n
Q1. if total cost is the same : 59 + 0.08n = 48 + 0.10n >>> 0.02n = 11 >>> n = 550
Q2. y = m + xn = 59 + 0.08n = 59 + 0.08(550) = 103

Answer:
Triangle
sum of interior = 180
one interior = 60
all triangles will have a sum of 180
and since there are only three angles in a triangle that means 180/3 = 60 degrees will be in one angle.
A car used 1/48 of a gallon of gas to drive 1/4 of a mile . At this rate , how many miles can the car travel using 1 gallon of gas
Answer:
12 miles
Step-by-step explanation:
Your car uses 1/12th of its entire gas to go a single mile. This means that you need to drive 12 miles to run out of gas.
Rafael runs 7 miles in 60 minutes. at the same rate, how many miles would he run in 24 minutes
Answer:
2.8 miles
Step-by-step explanation:
Speed of Rafael = 7 miles / 60 min = 7/60 miles/min
Time for next run = 24 min
Length of the next run = 7/60 miles/min *24 min = 2.8
A worker's wages w, are a function of the number of hours h worked at a rate of $10 per hour.
Answer:
w+h+10=10wh
Step-by-step explanation:
You can represent the measures of an angle and its complement as x °and (90 - x). Similarly, you can
represent the measures of an angle and its supplement as x and (180 - x )º. Use these expressions to
find the measures of the angles described.
The measure of an angle increased by 24° is equal to the measure of its complement.
The measure of the angle is
Jº and the measure of its complement is
Answer:
33°90° -J°Step-by-step explanation:
1)If x represents the measure of the angle, its complement is 90-x. The problem statement tells us ...
x +24 = 90 -x
2x = 66 . . . . . add x-24
x = 33 . . . . . . divide by 2
The measure of the angle is 33°.
__
2)Using J for x in the given complement relation:
The measure of the complement of J° is (90 -J)°.

Beard bought 10 acres of land.She plans to divide the land into smaller lots that are each 1/20 of an acre.How many smaller lots will she have.
Answer:She will have:
N = 200 smaller lots
Step-by-step explanation: N = (total acres of land) / (smaller lots of land)
Substituting the values we have:
N = 10 / (1/20)
Rewriting we have:
N = 10 * 20
N = 200 lots

Given that the shape is a kite and Angle A=25, Angle C=85, what is Angle
D?
Answer:
m∠D = 165°
Step-by-step explanation:
∠B and ∠C are congruent, so ∠B = 85°
The angles of the kite all added together have to add up to 360°
85 + 85 + 25 + x = 360
195 + x = 360
x = 165
Answer:
m∠D = 165°
Step-by-step explanation:
∠B and ∠C are congruent, so ∠B = 85°
The angles of the kite all added together have to add up to 360°
85 + 85 + 25 + x = 360
195 + x = 360
x = 165

use the midpoint formula to find the midpoint of the given segment on the coordinate plane
Answer:
Midpoint : (4,3)
Step-by-step explanation:
midpoint = [tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]
Where the x and y values are derived from the given points.
We are given points H and K which are at (2,2) and (6,4)
We have (x1,y1) = (2,2) so x1 = 2 and y2 = 2
As well as (x2,y2) = (6,4) so x2 = 6 and y2 = 4
To find the midpoint we simply plug in the values of x and y into the formula
Recall the formula [tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]
x1 = 2 , x2 = 6 , y1 = 2 and y2 = 4
plug in these values into the formula
[tex](\frac{2+6}{2} ,\frac{2+4}{2} )[/tex]
add top values: 2 + 6 = 8 and 2 + 4 = 6
[tex](\frac{8}{2} ,\frac{6}{2} )[/tex]
simplify fractions : 8/2 = 4 and 6/2 = 3
The midpoint is at [tex](4,3)[/tex]
What number could replace n?
6/12 = 2/n
n = ___
n = 4
Since you divide 6 by 3 to get 2, you divide 12 by 3 and you get 4.
Answer: 4
Step-by-step explanation: This problem is already set out as a proportion. you can cross multiply 6 times n which gives you 6n. Then 12 times 2 which gives 24.
Now you have 6n = 24. You can divide right away, or think of a number when you multiply into 6 gives you 24. Its obvious the answer is 4 because 6 x 4 = 24.
Check:
6/12 = 1/2
2/4 = 1/2
