A truck that can carry no more than 7600 lb is being used to transport refrigerators and upright pianos each refrigerator weighs 250lb and each piano weighs 425 lb. Write and graph an inequality to show how many refrigerators and how many pianos the truck could carry. Will 13 refrigerators and 11 pianos overload the truck? Explain.
Answers
Answer:
Step-by-step explanation:
7600 ≥ 250r+425p
7600 ≥ 250(13)+425(11)
7600 ≥ 3,250+4675
7600≥7925
This statement is incorrect. Therefore no, the truck cannot transport that load

Step-by-step explanation:
Given f(x) then f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift left of a units
• If a < 0 then a shift right of a units
Then
g(x + 3)² is the graph of f(x) translated 3 units left
Given f(x) then f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Then
g(x) = g(x + 3)² - 7 is the graph of f(x)
Translated 3 units left and 7 units down

The scale drawing of a field in the shape of a triangle is shown below. What is the actual area, in square meters, of this feild?
Answers
Answer:
The area of the field is 70 square meters
Step-by-step explanation:
Given
See attachment for scale drawing
Required
The actual area
From the scale drawing, we have;
[tex]Base = 7[/tex]
[tex]Height = 5[/tex]
So, the area of the scale is:
[tex]Area = 0.5 * Base * Height[/tex]
[tex]Area = 0.5 * 7 * 5[/tex]
[tex]Area = 17.5[/tex] square units
Also from the attached scale,
[tex]1\ unit = 2m[/tex]
So, we have:
[tex]Area = 17.5 * (2m)^2[/tex]
[tex]Area = 17.5 * 4m^2[/tex]
[tex]Area = 70m^2[/tex]
The area of the field is 70 square meters

A clock is divided into two equal parts.
(1) 1 - 6
(2) 7 - 12
When the hour hand is on (1), then the time is "after"
When the hour hand is on (2), then the time is "before"
From the attached clock, we have:
(1) The hour hand on 9
(2) The minute hand 1 unit above 9 i.e. 46 minutes
(1) implies that, the time is before 9 i.e. past 8
(2) implies that the minutes is (60 - 46) before 9 or 46 minutes after 8
In (1) and (2) above, we have two interpretations.
1: (60 - 46) minutes before 9
This gives:
14 minutes before 9
2: 46 minutes past 8
i.e. 8 : 46

The half life of a chemical element substance is 16 days, How long will it takes for the substance to decay from 120mg to 2 mg
Answers
Answer:
94.5 days
Step-by-step explanation:
We are asked to calculate the time.
The formula to calculate the time for half life =
t = t½ × In (Nt/No)/-In2
t½ = half life = 16 days
No = Initial substance = 120mg
Nt = Amount of substances after time t = 2 mg
t = 16 × In (2/120)/-In2
t = 94.510249529736 days
Approximately = 94.5 days
Therefore, the time it would take for the substance to decay from 120mg to 2 mg is 94.5 days.

rose watches a circular ornament that has 6 equally spaced stones. identify x
Answers
Answer:
x = 60°
Step-by-step explanation:
It is given that the stones are equally spaced. As the circle is divided into 6 parts by 6 split points and there are 360∘ in the circle, each part equals 360∘/6 = 60∘. So,
mAB◠ = 60∘
mBC◠ = 3 (60∘) = 180∘
If a tangent and a secant intersect in the exterior of a circle, then the measure of the angle formed is half the difference of the measures of its intercepted arcs.
x = 1/2 (mBC◠ − mAB◠)
Substitute the known values into the formula.
x = 1/2 (180∘ − 60∘)
= 1/2 (120∘)
= 60∘
Therefore, x = 60∘.

Answer:
x = 18
Step-by-step explanation:
Vertically opposite angles are equal.
x + x + x + 90 = 144
3x + 90 = 144
Subtract 90 from both sides
3x = 144 - 90
3x = 54
Divide both sides by 3
x = 54/3
x = 18
