Answer:
2400 grams
Step-by-step explanation:
The bears are fed from a 4 kg bucket each day. If the bears eat 3/5 of that bucket, therefore, the amount of fish that the bears eat is:
3 / 5 * 4 = 2.4 kg
Converting this to grams:
1 kg = 1000 g
2.4 kg = 2.4 * 1000 = 2400 grams
The bears feed is 2400 grams

The weight of a bag of golf balls varies directly as the number of golf balls in the bag. If a bag of 69 golf balls weighs 2,553 grams, how many golf balls are in a bag that weighs 1,110 grams? number of golf balls:
Answer:
30
Step-by-step explanation:
you do 2,553 divided by 69 which is 37
so u do 1,110 divided by 37
hope this helps
The number of golf balls that are in a bag that weighs 1,110 grams is 30.
How many golf balls are in the bag?When a variable varies proportionally, as the independent variable increases in value, the dependent variable also increases in value.
The equation that is used to present direct proportion is y = kx
Where:
y = dependent variablek= constant of proportionality x = indpendent variablek = 2553/69
k = 37
number of golf balls = 1110 / 37 = 30

Can someone help me with this i included a picture
Answer:
36
Step-by-step explanation:
Here, we shall be splitting the total length using the ratio given.
The total ratio is 3 + 1 = 4
Since AB is the bigger length, the ratio 3 belongs to it.
Thus; 3/4 * 48 is the length of AB
= 3/4 * 48 = 3 * 12 = 36

To determine the value of f(4)
As per the given functional relationship,
If the value of the domain is 4 then the value of the respective range would be 1/2.
Therefore, the function f(4) would be 1/2.
To determine the value of x, when f(x) = 4
As per the given functional relationship,
If the value of the range is 4 then the value of the respective domain would be 8.

Answer:
GH¢72,000
Step-by-step explanation:
Let total property=x

Total remaining
x-1/4x= 3/4x
2/3 of 3/4x=internal family
2/3×3/4x

Give that y is directly proportional to x. if y =6, x = 2 . (a) find the value of k (b) calculate y when x = 7 (c) calculate x when y = 30
Answer:
see explanation
Step-by-step explanation:
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
(a)
To find k use the condition y = 6, x = 2, then
6 = 2k ( divide both sides by 2 )
k = 3
y = 3x ← equation of proportion
(b)
When x = 7, then
y = 3 × 7 = 21
(c)
When y = 30, then
30 = 3x ( divide both sides by 3 )
x = 10
Answer: (a) k = 3
(b) y = 21
(c) x = 10
Step-by-step explanation:
Directly proportional uses the formula: y = kx
(a) Given y = 6 and x = 2, find k. 6 = k(2)
3 = k
(b) Given k = 3 and x = 7, find y. y = kx
y = 3(7)
y = 21
(c) Given k = 3 and y = 30, find x. y = kx
30 = 3x
10 = x

First identify the angle RELATIONSHIP, then find the measure of the angle indicated in bold.
Answer:
These angles are alternate exterior angles. Since they are congruent, to find the value of x we can write:
41x - 3 = 40x
x = 3 which means 40x = 40 * 3 = 120°.
Answer:
Alternate exterior angles
m∠ ≈ 120°
Step-by-step explanation:
Step 1: Set up equation
41x - 3 = 40x
Step 2: Isolate x and solve
x - 3 = 0
x = 3

Answer:
x+y=7
y= x+3
Step-by-step explanation:
i just took the test
The system of the equation that represents the given condition will be x + y = 7 and y = x + 3. And the solution is (2, 5).
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The sum of x and y is 7. The value of y is three more than the value of x. Then the equation is given as,
x + y = 7 ...1
y = x + 3 ...2
From equations 1 and 2, then we have
x + x + 3 = 7
2x = 4
x = 2
Then the value of the variable 'y' will be given as,
y = 2 + 3
y = 5
The system of the equation that represents the given condition will be x + y = 7 and y = x + 3. And the solution is (2, 5).

ABCD ~ FECG
z = [ ? ]
Answer:
Z=80°
Step-by-step explanation:
If the quadrilaterals are similar, they have the same angle measurements.
∠Z=∠F
Since all interior angles of a quadrilateral add up to 360°, we can subtract ∠E, ∠C, and ∠G's measurements from 360°.
360°-100°-120°-60°=∠Z
260°-120°-60°=∠Z
140°-60°=∠Z
80°=∠Z
∠Z=80°
The measure of angle z in quadrilateral ABCD is 80 degrees.
When two quadrilaterals are similar?Two quadrilaterals are similar quadrilaterals when the three corresponding angles are the same.
What is the sum of the interior angles of a quadrilateral?The sum of interior angles of a quadrilateral is 360 degrees.
According to the given question
We have two quadrilaterals ABCD and FECG, and they are similar to each other.
Since, ABCD and FECG are similar to each other.
Therefore, ∠BAD = ∠EFG
⇒ z = ∠EFG
Now, In quadrilateral FECG
We have
∠EFG + 100 + 120 + 60 = 360
( sum of the interior angles of a quadrilateral is 360 degrees)
⇒ ∠EFG + 280 = 360
⇒ ∠EFG = 360 - 280
⇒ ∠EFG = 80 degrees
Therefore, z = 80 degrees

In triangle ABC, AX = XY = YB = BC and the measure of angle ABC is 120 degrees. What is the number of degrees in the measure of angle BAC?
Answer:
the number of degrees=2
Answer:
15
Step-by-step explanation:
Let t be the number of degrees in the measure of angle BAC (which is what we want to compute).
Since AX=XY, we have AYX = YAX = BAC = t. Then, since the sum of angles in triangle AXY is 180, we have AXY = (180-2t).
Angles AXY and BXY add to form a straight angle, so they are supplementary; BXY = (180-(180-2t)) = (2t).
Since XY=YB, we have XBY = XY = (2t). Since the sum of angles in XYB is 180, we have XYB = (180-4t).
Angles AYX, XYB, and BYC add to form a straight angle, so their sum is 180. Therefore, BYC = (180-t-(180-4t)) = (3t).
Since YB=BC, we have YCB = BYC = (3t). Since the sum of angles in YBC is 180, we have YBC = (180-6t).
Finally, ABC = XBY + YBC = (2t) + (180-6t) = (180-4t). We know this is equal to 120, so we solve the equation 180-4t = 120 to obtain t=15.
