Answer:
(-8,8)
Step-by-step explanation:
<u>Answer:</u>
<u>ii) £120</u>
<u>iii) £2,400</u>
<u>a) 10 workers</u>
<u>c) 4 workers more to be employed.</u>
<u>Step-by-step explanation:</u>
ii) To find the buying price we deduct 20% (percent) from the selling price of £150.
= 20/100 x 150
= £30 (Next we substract this value from the selling price of £150) = €150 - £30 = £120
iii) A 12% interest per annum Implies a 12 percent of the borrowed amount of 20,000, which is calculated as
12% or 12/100 x 20,000 = £2,400
a) Put simply, we create an equation for the problem.
4 men * 10 days = 40 man days.
X men * 4 days = 40 man days.
Let's substitute the equation:
(X/ 4) * (4/ 10) = 40 / 40
(X/4) * 0.4= 1 (collect like terms)
0.4 * x = 4
0.4x/0.4= 4/0.4
x = 10 workers.
(c) 4 extra workers to would need to be employed since we have six already available (10-6=4).
Answer:
B.)
Step-by-step explanation:
In step #1 they did the distributive property
2/5 × 15x = 6x
2/5 × -30y = -12y
The new equation would be:
6x - 12y + 10x
<em><u>Further</u></em><em><u> </u></em><em><u>Explanation</u></em>
They then combined 6x + 10x to get 16x
16x - 12y
They then factored it out to 4(4x - 3y)
The measure of the value of x is 70.52 degrees.
Given
A 12-foot ladder is placed 4 feet away from a house as shown.
According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards.
<h3>What is cos angle?</h3>
The cos theta is defined as the ratio of the side adjacent to the angle and the hypotenuse.
The following formula is used to calculate the value of x;
Where the side adjacent to angle = 4 and hypotenuse is 12.
Substitute all the values in the formula;
Hence, the measure of the value of x is 70.52 degrees.
