Answer: He worked 40 hours that week.
Step-by-step explanation:
Given : The owner of an automotive shop devotes 90% of his workweek to supervising, sales and accounting tasks. In one week.
Let x = Number of hours he work in a week.
then, Hours for supervising, sales and accounting tasks = 90% of x
As per given ,
[tex]90\%\ of \ x= 36\\\\\Rightarrow\ 0.90x=36\\\\\Rightarrow\ x=\dfrac{36}{0.9}=\dfrac{360}{9}\\\\\Rightarrow\ x=40[/tex]
Hence, he worked 40 hours that week.

the following figures are similar, find the value of x
Answer:
x=143
Step-by-step explanation:
scale factor (if that is the correct term) is 13. you find that by matching sides to side. this means that 91/7=13, therefore you know that 4*13 is 52 and 11*13 is 143

Answer:
I think you multiply its height by its width for the area, the volume= LXWXH.
Step-by-step explanation:
Step-by-step explanation:
First , Split the given shape into two parts : Trapezium and rectangle :
Here , 18 m and 11 m are the opposite parallel side and (15-8) = 7m is the height of the trapezium.
[tex] \boxed{ \sf{Area \: of \: trapezium = \frac{1}{2} h(a + b)}}[/tex]
⤑ [tex] \tt{ \frac{1}{2} \times 7(18 + 11})[/tex]
⤑ [tex] \sf{ \frac{1}{2} \times 7 \times 29}[/tex]
⤑ [tex] \sf{101.5 \: {m}}^{2} [/tex]
Area of trapezium = 101.5 m²
In rectangle , 18 m is the length and 8 m is the width.
[tex] \boxed{ \sf{Area \: of \: a \: rectangle = l \times w}}[/tex]
⤑ [tex] \sf{18 \: m \: \times 8 \: m}[/tex]
⤑ [tex] \sf{144 \: {m}}^{2} [/tex]
Area of a rectangle = 144 m
Now , Finding total area of given shape :
[tex] \boxed{ \sf{Total \: area = Area \: of \: trapezium + area \: of \: a \: rectangle}}[/tex]
⤑ [tex] \sf{101.5 \: {m}^{2} + 144 \: {m}}^{2} [/tex]
⤑ [tex] \sf{245.5 {m}}^{2} [/tex]
[tex] \red{ \boxed{ \boxed{ \tt{⇾ \: Our \: final \: answer : \boxed{ \underline{ \tt{245.5 \: {m}^{2} }}}}}}}[/tex]

so I really need help. you have to set fractions equal to each other and try and find out how many prefer sweaters and whatnot. Also, the answer isn't supposed to be a fraction, it's supposed to be a whole number, you find the answer by using fractions with the information provided in the word problem above ^
I hope that makes sense. lol, thank you :)

The sum of magnitude of two vectors is 2√5.
What is Vector?A vector is a number or phenomena with two distinct properties: magnitude and direction. The term can also refer to a quantity's mathematical or geometrical representation. In nature, vectors include velocity, momentum, force, electromagnetic fields, and weight.
We have,
the magnitude of two vectors are 4 and 2.
and, The direction of two vectors are 45° and 135°.
According to vector addition,
The angle between both the vectors = 135 - 45 = 90
and, Sum of Vector
= √4² + 2²
= √16 + 4
= √20
Thus, the sum of magnitude of two vectors is 2√5.

suppose that the functions s and t are defined for all real numbers x as follows.
s(x)= x+6
t(x)= 4x2
write the expressions for (s.t)(x) and (s-t)(x) and evaluate (s+t)(-3).
Answer:
[tex](s.t)(x) = 4x^2+24x^2\\(s-t)(x) = x+6-4x^2\\(s+t)(-3) = 39[/tex]
Step-by-step explanation:
Given functions are:
[tex]s(x)= x+6\\t(x)= 4x^2[/tex]
We have to find:
(s.t)(x) => this means we have to multiply the two functions to get the result.
So,
[tex](s.t)(x) = s(x)*t(x)\\= (x+6)(4x^2)\\=4x^2.x+4x^2.6\\=4x^3+24x^2[/tex]
Also we have to find
(s-t)(x) => we have to subtract function t from function s
[tex](s-t)(x) = s(x) - t(x)\\= (x+6) - (4x^2)\\=x+6-4x^2[/tex]
Also we have to find,
(s+t)(-3) => first we have to find sum of both functions and then put -3 in place of x
[tex](s+t)(x) = s(x)+t(x)\\= x+6+4x^2[/tex]
Putting x = -3
[tex]= -3+6+4(-3)^2\\=-3+6+4(9)\\=3+36\\=39[/tex]
Hence,
[tex](s.t)(x) = 4x^2+24x^2\\(s-t)(x) = x+6-4x^2\\(s+t)(-3) = 39[/tex]

4x - 3y = 11
2x - 5y = 25
solve using elimination and substitution method
Answer:
hope it helps forget about my writing
Answer:
(-1.43, -5.57)
Step-by-step explanation:
Elimination:
First we need to line up x or y to be the opposite so they can be eliminated:
4x - 3y = 11
-2( 2x - 5y = 25) which is
-4x + 10y = -50
Next step we cancel out the x but adding both equations which would isolate the y:
7y = -39
y = -5.57
After finding y, plug it back into the equation to find x:
4x - 3(-5.57) = 11
4x + 16.71 = 11
4x = -5.71
x = -1.43
To ensure it is correct, we can plug it back into both equations:
4(-1.43) - 3(-5.57) = 11
2(-1.43) - 5(-5.57) = 25

A card is chosen at random from a standard deck of cards. What is the probability that the card chosen is a heart or spade? Are these events mutually exclusive?
Answer:
a. Probability is 50%
b. Picking either a heart or spade is mutually exclusive
Step-by-step explanation:
There are 52 cards in a deck of cards.
Of those 52, 13 are hearts and 13 are spades.
The probability of picking wither of them is therefore:
= (13 + 13) / 52
= 26/52
= 50%
Mutually exclusive events are those that cannot occur at the same time. You can either pick a heart or you can pick a spade. You cannot pick both at the same time so these are mutually exclusive.

a person runs around a square field of side 70m, while another person runs around a rectangular field with length 90m and breadth 60m. Who covers more distance by how much?
[tex]\huge\underbrace\red{Answer}[/tex]
Given :- Side of the square field = 70mLength of the rectangular field = 90mBreadth of the rectangular field = 60mTo Find :- Perimeter of the square fieldPerimeter of the rectangular fieldSolution :-Perimeter of the square = 4 × side
By substituting values,
⇒ 4 × 70m
➥ 280m
Hence, A Person runs 280m around a Square fieldPerimeter of the rectangle = 2( length + Breadth)
By substituting values,
⇒ 2( 90m + 60m )
⇒ 2( 150m)
➥ 300m
Hence, A Person runs 300m around a rectangular fieldDifference between perimeters of fields = Perimeter of Rectangular field - perimeter of square field
By substituting values,
⇒ 300m - 280m

The stage manager of a school musical is trying to figure out how many sandwiches he can order with the $83 he collected from the cast and crew. Sandwiches cost $5.99 each, so he lets x represent the number of sandwiches he will order and writes 5.99x < 83. He solves this to two decimal places and gets x < 13.86.
Which of these are valid statements about this situation? Select all that apply.
1) He can call the sandwich shop and order exactly 13.86 sandwiches.
2) He can round up and order 14 sandwiches.
3) He can order 12 sandwiches.
4) He can order 9.5 sandwiches.
5) He can order 2 sandwiches.
6) He can order -4 sandwiches.
Justify your answer(s).
Answer:
Step-by-step explanation:
1) it is not this answer because you cant order 13.86 sandwiches. it has to be a whole number.
2) Not this answer. If he bought 14 sandwhichs hed have to pay 83.86 and he doesnt have 36 cents xtra.
3) He CAN order 12 sandwhiches. if he has $83 and if you bought twelve sandwiches he would spend $71.88 which is still within the range he can buy from.
4) He CANNOT order .5 of a sandwhich so i wouldnt select this one.
5) He CAN order 2 sandwhiches. he has enough money for that
6) he CANNOT order negative amount of sandwhiches.
