what is the slope of a line that contains the points (-6, 1)and (4 negative 4)
4 2– 3 × 2 × ( 7 3 ÷ 7 6 )
Answer:
36.24
Step-by-step explanation:
- 3 * 2 = - 6
73 / 76 = 0.96
0.96 * (-6) = -5.76
42 - 5.76 = 36.24
Miguel is ordering 6 bags of cat food from Canada. Each bag has a mass of 7.5 kg. To determine the shipping costs, Miguel needs to know the total weight in pounds. What is the weight of the cat food in pounds? Use 1 kg = 2.2 lbs and do not round any computations.
Answer:
99 pounds
Step-by-step explanation:
7.5×6=45kg
1kg=2.2lb and we have 45kg because this is direct proportion what you do to one side you havbe to do to the other
so 2.2lb×45 gives you 99 pounds

solve the inequality below. use the drop down menus to describe the solution and its graph -7x+13 ≥41
Answer:
x ≥-4
Step-by-step explanation:
-7x+13 ≥41
-7x ≥28 (subtraction property of equality on both sides-subtract 13)
x ≥-4 (division property of equality on both sides-divide by -7)

A famous monument is 300 ft tall. When it casts 210-ft shadow, a nearby tree casts a shadow that is 27 ft long. About how tall is the tree?
Answer:
38.57 feets
Step-by-step explanation:
Given that:
Height of monument, h = 300ft
Shadow of monument, s = 210 ft
Shadow of tree, s = 27ft
Height of tree, = x
Using the relation :
Height / shadow = height / shadow
Monument = tree
300 / 210 = h / 27
Cross multiply
300 * 27 = 210 * h
8100 = 210h
h = 8100 / 210
h = 38.57 feets

At the zoo, Peter saw 9 animals. Some are kangaroos and some are
elephants. There are 30 legs in all. How many of each animal are there?
Answer:
6 elephants and 3 kangaroos in the zoo.
Step-by-step explanation:
Number of animals = 9
Number of legs seen = 30
But an elephant has 4 legs, while a kangaroo has 2 legs.
Let the number of elephant be represented by E, and the number of kangaroo by K.
So that,
E + K = 9 .................. 1
4E + 2K = 30 ............. 2
Multiply equation 1 by 2 to have
2E + 2K = 18 ............ 3
Subtract equation 3 from 1
2E = 12
E = 6
Substitute the value of E in equation 1
E + K = 9
6 + K = 9
k = 3
Thus, there were 6 elephants and 3 kangaroos in the zoo.

1.How many pounds of walnuts that cost $0.80 per pound must be mixed
with 8 pounds of cashews that costs $1.25 per pound to make a mixture of
nuts that costs $1.00 per pound?
2.A chemist needs to mix a 12% acid solution with a 32% acid solution to
obtain an 8‐liters mixture consisting of 20% acid. How many liters of each of
the acid solutions must be used?
9514 1404 393
Answer:
1012%: 4.8 L; 32%: 3.2 LStep-by-step explanation:
For mixture problems, I like to use a single variable to represent the quantity of the greatest contributor (greatest cost or greatest concentration). Let that variable be x.
1. In this problem, the amount of the greatest contributor is already fixed, so we'll use x for the amount of walnuts. The cost of the mix is ...
0.80x + 1.25(8) = 1.00(x +8)
2 = 0.2x . . . . . . . . . . . . . . . . . subtract 0.8x+8, simplify
10 = x . . . . . . . . . divide by 0.2
10 pounds of walnuts must be used.
__
2. The amount of acid in the mix is ...
12%(8 -x) +32%(x) = 20%(8)
20%(x) = 8%(8) . . . . . . . . . . . . subtract 12%(8)
x = 8(8)/20 = 3.2 . . . . . . . . . . divide by 20%
8-x = 4.8
3.2 liters of 32% acid must be mixed with 4.8 liters of 12% acid

Comment on mixture problems
The general solution for mixture problems that have a greater contributor (G), a lesser contributor (L), and a mix value (M) is ...
g/l = (M -L)/(G -M) . . . . . . ratio of quantities of G and L
In the first problem, this becomes ...
8/l = (1.00 -.80)/(1.25 -1.00) = .2/.25 = 4/5 ⇒ l = 8(5/4) = 10
In the second problem, this becomes ...
g/l = (20-12)/(32-20) = 8/12 = 2/3 ⇒ g = (2/5)(8) = 3.2; l = (3/5)(8) = 4.8
In this case, we recognize that the ratio of 2 parts to 3 parts means that the greater contributor is 2 of 5 total parts.
What is the equation of a circle centered at the origin with radius 20
Answer:
we have a rule
(x-h)²+(y-v)²=r²
while h is the x intercept
v is y intercept
r is the radius
so the answer will be
x²+y²=400
or
x²+y²=20²
Tim is constructing a triangle with sides measuring 3 inches and 6 inches. Which could not be the length of the third side? A 2 in. B 4 in. C 6 in. D 8 in.
Find a correct to 2 decimal places.
NOTE: The triangle is NOT drawn to scale.
102
27°

х
Answer:
317.52
Step-by-step explanation:
Label the point where the altitude meets the base P and the end points of the base A and B where m∠A = 27 and m∠B = 41
tan 27 = 102/AP and tan 41 = 102/PB
APtan 27 = 102 PBtan 41 = 102
AP = 102/tan 27 PB = 102/tan 41
AP = 200.186 PB = 117.338
x = AP + PB = 200.186 + 117.338 = 317.52
