Hi, Please i need help with this question. Workings would be deeply appreciated .
A straight line which passes through the point (3,-4) makes intercept 3k and -5k on the x and y axes respectively. Find the value of k
Answer:
k = ⅕
Step-by-step explanation:
The slope-intercept equation for a straight line is
y = mx + b, where
m = the slope and
b = the y-intercept
Data:
(3,4) = a point on the line
(3k,0) = x-intercept
(0,-5k) = y-intercept
Calculations:
1. Slope
m = (y₂ - y₁)/(x₂ - x₁) = (-5k - 0)/(0 - 3k) = -5/(-3) = ⁵/₃
This makes the equation
y = ⁵/₃x - 5k
2. k
Insert the value of the known point: (3,4)
4 = (⁵/₃)(3) - 5k
4 = 5 - 5k
-1 = -5k
k = ⅕
The figure below shows your graph passing through (3,4) with intercepts 3k and -5k on the x- and y-axes respectively .

Answer:
In geometry, an angle measure can be defined as the measure of the angle formed by the two rays or arms at a common vertex.
Step-by-step explanation:
Angles are measured in degrees ( °), using a protractor. The protractor was invented by Joseph Huddart in 1801. It was a more complex form of protractor. hope this helps you :)
Mrs.thapa bought 150 kg of oranges.18 kg of oranges were rotten and not fit for selling.If she sold the remaining quantity of oranges at the rate of Rs 80 per kg and gained 10%. Find the rate of cost price of oranges.
Help!!
Answer:
Rs.64
Step-by-step explanation:
Amount of oranges:
150 kgOranges sold:
150 - 18 = 132 kgMoney made:
132* 80 = Rs. 10560Selling price of 150 kg:
10560/150 = Rs. 70.4Cost price:
x+10% = 70.4x*1.1= 70.4x= 70.4/1.1x= Rs.64Cost price of oranges= Rs. 64Answer:
Rs64.00/kg
Step-by-step explanation:
1. Calculate the amount of good oranges
Total amount of oranges = 150 kg
Amount of rotten oranges = 18 kg
Amount of good oranges = 132 kg
2. Calculate the income from the good oranges
[tex]\text{Income} = \text{132 kg} \times \dfrac{\text{Rs80}}{\text{1 kg}} = \text{Rs10 560}[/tex]
3. Calculate the net unit rate of income
The income from the good oranges was Rs10 560.
Based on 150 kg of oranges, the unit rate of income was
[tex]\text{Unit rate of income} = \dfrac{\text{RS10 560}}{\text{150 kg}} = \text{Rs70.40/kg}[/tex]
4. Calculate the original unit rate of cost
Let x = original unit cost. Then
0.10x = 10 % of original unit cost and
1.10x = 10 % over original unit cost
1.10x = RS70.40/kg
x = (RS70.40/kg)/1.10 = Rs64.00/kg
The original unit rate of cost was Rs64.00/kg.

Step-by-step explanation:
Given that points A, B, and C are the midpoints of their respective sides, which of the following is true about the figure? ANSWERS: A) ∠Y ≅ ∠Z B) ∠X ≅ ∠ACB C) || D) ||
Answer:
The correct option is;
[tex]\overline{YZ}\left | \right | \overline{AC}[/tex]
Step-by-step explanation:
The dimensions given are;
YX = 2 × AX (A = midpoint of YX)
ZX = 2 × CX (C = midpoint of ZX)
∠X and ∠X are congruent (Reflexive property)
Therefore, triangle XAC is similar to triangle XYZ (SAS similarity theorem)
Since ∠XYZ = ∠XAC segments YZ and AC are parallel from having equal angle on the same side of the transversal YX
Therefore the correct option should be;
[tex]\overline{YZ}\left | \right | \overline{AC}[/tex]
Answer:ΔBCZ ≅ ΔYAB
Step-by-step explanation: since we know the midpoint are <ABC we can see the that answer is correct.
BD is the bisector of ∠ABC. Determine the measure of ∠ABD. ANSWERS: A) 90° B) 55° C) 40° D) 45°
Answer:
D) 45
Step-by-step explanation:
When a line bisects an angle, it cuts the angle into two equal halves. This means that ABD and DBC have the same angle measure, which is half of 90 degrees or 90/2=45. Hope this helps!

Which of the following options best describes the solution process and solution(s) for the quadratic equation? -2x2 + 3x + 4 = 7
Answer:
Step-by-step explanation:
If there are options, please share them.
Subtract 7 from both sides. We obtain: -2x^2 + 3x - 3. The coefficients of this quadratic are a = -2, b = 3 and c = -3. Thus, the discriminant is
b^2 - 4ac, or 3^2 - 4(-2)(-3), or 9 - 24, or -15. Because the discriminant is negative, this quadratic has two complex roots which differ:
-3 ± i√15

Help please anyone ??
Answer:
x=83
Step-by-step explanation:
97+x=180
x=83
Answer:
∠x = 83°
Step-by-step explanation:
Since ∠x and ∠y are supplementary ∠s so they add up to 180°
So,
∠x + ∠y = 180
Where ∠y = 97°
∠x + 97° = 180
∠x = 180-97
∠x = 83°
Solids X and Y are similar.
X has volume of 64 cm3
Y has volume of 729 cm3
The surface area of X is 208 cm2
Work out the surface area of Y.
Answer: 2,369.25 cm3
Step-by-step explanation:
Hi, to answer this question we have to use proportions:
X has volume of 64 cm3 and s surface area of 208 cm2
The proportion is = volume / surface area = 64/208
Y has volume of 729 cm3
Volume / surface area = 729/ s (surface area of y)
64/208 = 729/ s
Solving for s:
s = 729 / (64/208)
s = 2,369.25 cm3

7. Jonah's fishing license allows him to catch up to 20 pounds of fish in a particular lake. He
catches 4 fish
I
weighing 12 lb 3 oz, 2 lb 15 oz, 7 lb 1 oz, and
10 oz.
a) What is the total weight of the fish Jonah
caught?
b) Jonah wants to throw back one fish to remain under his limit. Which is the smallest fish he
can throw
back
?
Answer:
a. total weight = 22.8125 pounds
b. 2 pounds 15 oz
Step-by-step explanation:
His license only allows him to catch a 20 pounds fish. He catches 4 fishes with the following weight.
12 pounds 3 oz , 2 pounds 15 oz, 7 pounds 1 oz and 10 oz.
a. The total weight of fishes he caught is calculated when you add the whole weight of the 4 fishes. Firstly let's convert the oz to pounds
16 ounces = 1 pounds
29 ounces = ? pounds
cross multiply
29/16 = 1.8125 pounds
12 + 2 + 7 = 21 + 1.8125 = 22.8125 pounds
total weight = 22.8125 pounds
b. The total weight he caught is above what the license allows him. Therefore, 22.8125 - 20 = 2.8125 pounds. The fish that has such weight is the fish with 2 pounds 15 oz so, that is the fish he will throw back to the lake.

There are 50 children on the school basketball team, 60% of
the children are senior students. 80% of the seniors and 40%
of the juniors stay at the after-school program. How many more seniors than juniors stay at the after-school program?
Answer: 16 more seniors than juniors stay at the after-school program
Step-by-step explanation:
50 * 60% = 50 * .6 = 30
30 * 80% = 30 * .8 = 24
50 - 30 = 20
20 juniors and 30 seniors in total
———————————————
20 * 40% = 20 * .4 = 8

Answer: 45°
Step-by-step explanation:
Given that :
∠A=5x−15°---(1)
∠B=2x+21°----(2)
Equating
∠A = ∠B
(5x−15)° = (2x+21)°
5x - 15 = 2x + 21
Collecting like terms
5x - 2x = 21 + 15
3x = 36
x = 12
Substitute x = 12 in either angle A or B since both are congruent
∠A=(5x−15)°
∠A = (5(12) - 15)°
∠A = (60 - 15)°
∠A = 45°
∠A = ∠B = 45°
