Answer:
10° and 80°
Step-by-step explanation:
Complementary angles sum to 90°
let one angle be x then the other angle is 7x + 10 , so
x + 7x + 10 = 90
8x + 10 = 90 ( subtract 10 from both sides )
8x = 80 ( divide both sides by 8 )
x = 10
and 7x + 10 = 7(10) + 10 = 70 + 10 = 80
Thus the 2 angles are 10° and 80°

What are the transformations on the following
function, f (x) = -2 log4 (x + 5) - 4?
Answer:
8
Step-by-step explanation:
= f (x) = -2 log 4 (x + 5) - 4
= 4 (-2 + 5) - 4
= So you do -2 + 5 because they are in ( ) so you do it first so (-2 + 5) = 3
= So now you have 4 (3) - 4
= You do 4 and (3) because when you have a 4 by a ( ) that means you multiply.
= 4 (3) which is the same as 4 × 3 which is 12.
= then you do 12 - 4 which is 8.
= 8 is your answer.
I hope this helps.

Answer:
the actual answer is 20.625 and since there aren't any choices I'll give u my estimated answer: 20
Step-by-step explanation:
I got my estimated answer by rounding each length of rope down or up according to if it was less than 4/8 or higher. example: rounded 7 7/8 to 8

Miguel has a ball of modeling clay that has a diameter of 3.5 centimeters. The cylindrical container it is placed in has a base area of 7.1 square centimeters and a height of 5 centimeters. What is the volume of empty space in the container?
Answer:
48.1 cubic meters or 48100000 cubic centimeters
Step-by-step explanation:
Firstly we need to find the radius.To find that we divide the diameter by two.3.5÷2=1.75
Volume of Cylinder=Pi×radius squared×height
Lastly 3.14×1.75×1.75×5=48.1

Q1 - Finding simple interest
Find the simple interest on a loan of:
£7500 borrowed for 6 years at a
rate of 12% p.a.
interest = £
Answer:
£ 5400
Step-by-step explanation:
P = £ 7500
r = 12% = 0.12
t = 6 years
Simple Interest = P*r*t
= 7500 * 0.12 * 6
= £ 5400

Answer:
w+6=8 and w=2
Step-by-step explanation:
2(w+6) = 16
divide by two on both sides to remove the 2
w+6=16/2
w+6=8
-6 (remove six from both sides)
w=2

Write an equation of a line that goes thru the points (-2, 6) & (3, -4)
Answer:
y= -2x +2
Step-by-step explanation:
The equation of a line can be written in the form of y= mx +c, where m is the gradient and c is the y-intercept. This form is known as the slope-intercept form.
To find the value of m, use the gradient formula below:
[tex]\boxed{gradient = \frac{y1 - y2}{x1 - x2} }[/tex]
[tex]m = \frac{6 - ( - 4)}{ - 2 - 3}[/tex]
[tex]m = \frac{6 + 4}{ - 5} [/tex]
[tex]m = \frac{10}{ - 5} [/tex]
m= -2
Substitute m= -2 into the equation:
y= -2x +c
To find the value of c, substitute any pair of coordinates that the line passes through into the equation. Here, I am going to substitute the coordinates (3, -4).
y= -2x +c
When x= 3, y= -4,
-4= -2(3) +c
-4= -6 +c
c= -4 +6
c= 2
Thus, the equation of the line is y= -2x +2.
Jason purchased three different sizes of candy at the store. The
medium candy was twice as expensive as the small candy. The large
candy was $5 more than the medium candy. He spent a total of $30 on
candy. Write and solve an equation to determine the cost of the small
candy.
Answer: $5
Step-by-step explanation:
Let the small candy be represented by x.
The medium candy was twice as expensive as the small candy. This will be: = 2×x = 2x
The large candy was $5 more than the medium candy. This will be: = 2x + 5
Since Jason spent a total of $30 on
candy, the cost of the small candy will be:
x + 2x + 2x + 5 = 30
5x + 5 = 30
5x = 30 - 5
5x = 25
x = 25/5
x= 5
The small candy cost $5
