A 40cm length of wire is used to form a rectangle. The width of
the rectangle is 2cm longer than the height.
What is the length of the shortest side?
Answer:
9cm
Step-by-step explanation:
to solve first divide the total perimiter (40cm) by 4
this would allow 10cm for each side to allow the longer side to be 2 cm longer than the height we must subtract 1cm (for a total of 2cm) from each side of the rectangle, this would result in the shorter side having a length of 9cm
40=2 x (9+11)
Tim has completed five math problems and 13 minutes if he continues at the same rate how long will it take him to finish 20 problems
Answer:
52 minutes
Step-by-step explanation:
it takes him 13 minutes to complete 5 so if he wants to do 20 problems do 20 divided by 5 (4) then do 13 times 4=52
If lines a and b are parallel determine the value of x.
==================================================
Work Shown:
If line a is parallel to line b, then the alternate interior angles (4x-30) and (2x) are equal to one another.
Let's solve for x
4x-30 = 2x
4x-2x = 30
2x = 30
x = 30/2
x = 15

Robert runs 2 1/3 laps in 4 1/3 minutes. At this rate how long will it take to run 3 laps?
Answer:
7
Step-by-step explanation:
This is easy. You simply see what 2 1/3 is of 3. The answer is 7.
Please make brainliest!
Answer:
[tex]5 \frac{7}{50}[/tex]
Step-by-step explanation:
we can write the following ratios
laps:time
2.333:4.3333
3:x
To solve this just multiply 4.333 by 1.28571428571 (this is what we mulitplied 2.333 by to get 3)
do this and round to get 5.14 minutes
let's convert this into a fraction just in case
5.14= 514/100 = 257/50 = 5 7/50
Suppose g(x) = f(x - 1) - 5. Which statement best compares the graph of
g(x) with the graph of f(x)?
D is your answer i believe
Step-by-step explanation:
using g(x), -1, which is our change of x will go right. -5 is our change in y, so therefore it goes down. negative means down, positive means up for our change of y. for our change of x, negative goes right, and postive goes left. thats why i think the answer is d

The floor of a rectangular living room is 12 feet by 16 feet. What is the distance between
opposite corners of the living room?
Answer:
The width of Dana's living room is 16 feet.
Explanation:
Because Dana's living room is rectangular and we are given the length of one side and the length of the diagonal we can use the Pythagorean Theorem to solve this problem.
For a right triangle which the length, width and diagonal make up the Pythagorean Theorem states:
a
2
+
b
2
=
c

Let the length of 12 be
a
and because the diagonal is the hypotenuse of the triangle (the side opposite the right angle) we let
c
be 20. Substituting and solving gives:

please help me, I am so confused. Thanks
Answer:
c. 80
Step-by-step explanation:
cos x = sin(x-70)
cos x = cos [90-(x-70)]
cos x = cos (90-x +70)
cos x = cos 160 -x
x= 160-x
2x = 160
x =80

Someone help me (10 points each person)
Answer:
x=56
Step-by-step explanation:
Alternate exterior angles are congruent if the lines crossed by the transversal are parallel (which they are).
Answer:
56
Step-by-step explanation:
It would also be 56 degrees because if both 360 degree angles are parallel to each other and if each of the 360 degree angles had two top and bottom 180 degree angles and if 56 was subtracted to 180 you would get 124 and when you plus that with 56, you get 180 so if that is true for all 4 180 degree angles in this problem, then X would equal 56 no doubt.
The scale on a map of Oregon is 1 inch = 5000 feet What is the scale factor?
Answer:

Answer:
C. The y-intercepts of the two functions are opposites.
Step-by-step explanation:
The y-intercept of g(x) is -1 and the y-intercept of h(x) is 1. -1 and 1 are opposites, so the two y-intercepts are also opposites.
2) Abby spent $152 on Math Team spirit gear. Sweatshirts cost $25 and t-shirts cost $11. If she
bought a total of 10 items, how many of each type of shirt did she buy?
Answer:Abby bought 3 sweat shirts and 7 t shirt
Step-by-step explanation:
Step 1
Let sweat shirt be represented as s
and t shirts be represented as t
such that the total umber of items bought which equals 10 can be written as
s+ t= 10---- equation 1
and total price of the gear with each item costing $25 on sweatshirt $11 on t-shirts be expressed as
25 s+ 11 t = 152---- equation 2
Step 2
s+ t= 10-----equation 1
25s+ 11t= 152----equation 2
By elimination method , multiply equation 1 by 10 and subtract equation 2 from it
25 s+ 25t= 250----- equation 3
-25s + 11t= 152-----equation 2
14t=98
t=98/14= 7
To find s, using equation 1
s+t=10
s= 10-7= 3
Abby bought 3 sweat shirts and 7 t shirt

HELP MEEEE!!!!!!!!!!!!!!!!!!!! I will give brainliest to whoever answers first.
i would like to know this question and can you show your work to so I can understand
Answer:
162
Step-by-step explanation:
a=[tex]\frac{a+b}{2} h[/tex]
a=base and the base is 13 ft.
b= also means base which is 23 ft.
h= height which is 9 ft.
so 13+23 is 36
36/2 is 18
and 18 times 9 is 162

In parallelogram ABCD, AB = (2x + 15) and 4C = x. Find x.
O55
O60
O15
O45
Answer:
x = 55
Step-by-step explanation:
ABCD is a paralellogram, m∠ABC = 2x + 15, m∠BCD = x
m∠ABC + m∠BCD = 180° (same side interior angles)
2x + 15 + x = 180
3x + 15 = 180 -15
3x = 165
x = 55
