The calories I burn walking can be modeled by the function y = 5x + 100,
with x representing the number of minutes spent walking. How many
calories would I burn if I walked for 75
minutes?
Answer:
X=75
Y=5X+100
Y=5*75+100
Y=375+100
Y=475
Therefore, you burnt 475 calories if you walked for 75 minutes

Question 27
27. If an increase in one quantity brings about a corresponding decrease in the
other and vice versa, then the two quantities vary
a) sometimes directly and sometimes inversely b) directly
c) inversely d) none of these
ОА
Ов
Ос
OD
Answer:
c) inversely
Step-by-step explanation:
In Mathematics an inverse relationship can be defined as a relationship between two variables, in which an increase in the value of one variable leads to a decrease in the value of the other variable i.e as the value of one variable becomes large, the value of the other variable becomes small.
Mathematically, an inverse relationship is given by the formula;
A = K/B
Where;
A and B are the variables.
K is the constant of proportionality.
Hence, if an increase in one quantity brings about a corresponding decrease in the other and vice versa, then the two quantities vary inversely.
Y=-2x^2+16x-35
Axis of Symmetry?
Answer:
Step-by-step explanation:
y=-2x²+16x-35
=-2(x²-8x+16-16)-35
=-2(x²-8x+16)+32-35
=-2(x-4)²-3
axis of symmetry is x-4=0
or x=4
Answer:
y=2x^2+16x-35

Step-by-step explanation:
this is a right angled triangle
this question will be solved by Pythagoras theorem
which states square of hypotenuse=square of legs
so 35= 21sqr+b sqr
1225=441+b sqr
b sqr= 1225-441
b sqr=784
b= sqr root of 784
= 28 yards
perimeter=1/2multiplied to base to height

Step-by-step explanation:
Mrs. Via needs to buy
grass seed for her yard. She drew a diagram
of her yard. Each square represents 1 square
yard. Five pounds of seed is enough to plant
100 square yards of grass. Grass seed is sold in
2-pound bags. How many bags of grass seed
does Mrs. Via need?
Answer:
Step-by-step explanation:
Via needs 2 1/2 bags of grass seed
The number of bags of grass seed that Amanda should use to spread her yard is 16.65 bags, meaning she needs to buy not more than 17 bags, using mathematical operations.
What are mathematical operations?The basic mathematical operations we use are subtraction, addition, division, and multiplication.
In this situation, we use the division operation.
The division operation involves four parts:
The dividend (numerator or the number being divided).
The divisor (denominator or the number dividing).
The quotient (the result of the division operation).
The equal symbol (that shows that two values are equal).
The area of the yard = 4,995 ft²
1 yard = 3 feet
Area of the yard = 1,665 square yards(4,995/3)
The number of bags per 100 square yards = 1 bag
For 1,665 square, the number of bags = 16.65 bags (1,665 ÷ 100)
Thus, Amanda requires 16.65 bags of the grass seed for her yard.

A solid sphere is cut into 8 equal wedges. The volume of each wedge is
V= dor? Solve the formula for r.
O A. r =
6V
B. r = 6V – 7
O c. r= = v
OD. r= 16V (11)
Answer:
A) r=∛(6v)/[tex]\pi[/tex]
Step-by-step explanation:
v=1/6[tex]\pi[/tex]r³
v÷1/6=[tex]\pi[/tex]r³
(when dividing by a fraction, invert and multiply)
6v=[tex]\pi[/tex]r³
6v÷[tex]\pi[/tex]=r³
(6v)/[tex]\pi[/tex]=r³
take the cube root of both sides
∛(6v)/[tex]\pi[/tex]=∛r³
∛(6v)/[tex]\pi[/tex]=r

Find the following
(u•w)(2)=
(w•u)(2)=
Step-by-step explanation:
substitute 2 into x
1. (u ○ w)(2)
u(w(x))
= 4(-5x+1)+2
= 4(-5.2+1)+2
= 4(-9)+2
=-34
2. (w ○ u)(2)
w(u(x))
= -5(4x+2)+1
= -5(4.2+2)+1
= -5(10)+1
= -49

You invested S3000 between two accounts paying 4% and 8% annual interest respectively if the total interest eamed for the year was S520 how much was invested at each ratė? was invested at 4% and so was invested at se
Answer:
Even investing the $ 3,000 in the account at 8%, the result would be an annual interest of $ 240, with which there is an error in the wording of the question.
Step-by-step explanation:
Given that you invested $ 3000 between two accounts paying 4% and 8% annual interest respectively, to determine how much was invested at each rate if the total interest eamed for the year was $ 520, the following calculation must be performed:
3000 x 0.04 + 0 x 0.08 = 120
1500 x 0.04 + 1500 x 0.08 = 180
3000 x 0.08 + 0 x 0.04 = 240
Thus, as can be seen, even investing the $ 3,000 in the account at 8%, the result would be an annual interest of $ 240, with which there is an error in the wording of the question.
What is the answer for 5 × (-2w - 4)
Answer: -10w-20
Step-by-step explanation:
Because the number is in front of the bracket you have to times everything inside the bracket by the number on the outside.
5x-2w= -10w (you would basically do 5x-2 which is -10 then put the w on the end of it).
5x-4= -20
Then put it together so -10w-20
