An angle measures 10° less than the measure of its supplementary angle. What is the measure of each angle?​

Answers

Answer:

The two angles are 85 and 95 degrees

Step-by-step explanation:

Supplementary angles add to 180

Let x be one angle

The supplement is 10 less,  ( x-10)

They add to 180

x+ ( x-10) = 180

2x -10 = 180

Add 10 to each side

2x-10+10 =180-10

2x= 190

Divide by 2

2x/2 =190/2

x=95

The other angle is 95-10 = 85

The two angles are 85 and 95 degrees

First find 16% of 42 which is just 16/100×42 which is 6.72 and then added 42

Answer:

48.72

Step-by-step explanation:

your old value =42

your new value = let it be x

your original percentage =100percent

your new percentage:100+16

=116percent

old. new

value. 42. x

percentage 100. 116

cross multiply :x multiply by 100=42 multiplyby 116

100x=42x116

x=42x116/100

x=48.72

So, your increased value is 48.72

A shop sells school uniform.
Two shirts and one jumper cost £29
One shirt and one jumper cost £21
How much does one jumper cost?
£

Answers

Answer:

Jumper costs £13

Step-by-step explanation: (s = shirt j = jumper)

We know that 2s + 1j = £29

We also know that 1s + 1j = £21

29-21 = £8

This means that the shirts cost £8  each

We now need to multiply: 8 x 2 = £16  which means that the shirts in total cost £16

So, 29 - 16 = £13  which means one jumper costs £13

The cost of one jumper is $13.

What is an equation?

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, two shirts and one jumper cost £29 while one shirt and one jumper cost £21, we need to find the cost of one jumper,

Let jumper is represented by j and that of shirt by s,

Establishing the equations,

2s + j = 29

j = 29 - 2s......(i)

s + j = 21

j = 21 - s.......(ii)

Solving the equations,

21 - s = 29 - 2s

s = 8

Put s = 8 in eq (ii)

j = 21 - 8

j = 13

Hence, the cost of one jumper is $13.

A sphere has a diameter of 12 ft. What is the volume of the sphere? Give the exact value in terms of Pi.

Answers

Formula of volume of a Sphere is : V = 4/3 πr³

Here, Diameter (2r) = 12, so radius (r) = 12/2 = 6 feet

Substitute it into the formula,

V = 4/3 π(6)³

V = 4/3 *216π

V = 288π Ft² [ Answer in the term of π ]

You can also solve it for numeral value by substituting the value of π = 22/7

V = 288 * 22/7 = 905.15 Ft² [ Answer in numbers ]

Parallel, Perpendicular, or Neither?
Please let me know an explanation would be great I hate my math teach but thank you!

Answers

Answer:

Step-by-step explanation:

Both equations are in slope-intercept form, so the coefficient of x is the slope of the line.

y = 4x-3

slope = 4

y = (¼)x + 3

slope = ¼

If the slope are the same, the lines are parallel. If the product of the slopes = -1, the lines are perpendicular.

4×¼ = 1

The lines are neither parallel nor perpendicular.
