Answer 1

Answer:

x = 37.5

Step-by-step explanation:

By Basic Proportionality Theorem:

[tex] \frac{x}{20} = \frac{46 - 16}{16} \\ \\ \frac{x}{20} = \frac{30}{16} \\ \\ x = \frac{20 \times 30}{16} \\ \\ x = \frac{600}{16} \\ \\ x = 37.5[/tex]

Answer 2

Answer:

x=37.5

Step-by-step explanation:

16/20=30/x

Step-by-step explanation:

surface area is 3.8x3.8x6

but minus one side is 3.8x3.8x5 = 72.2

Answer:

72.2 square meters

Step-by-step explanation:

multiply the length by the width

3.8 x 3.8 = 14.44

in a cube there are 6 sides; however, it says Sarah is painting all the sides except for one so she is only painting 5 sides

14.44 x 5 = 72.2

differentiate y=a/x+b with respect to x, when a and b are constant​

Answers

Answer:

-a/(x+b)²

Step-by-step explanation:

Given the function y = a/x+b

To differentiate, we will use the quotient rule.

dy/dx = (Vdu/dx-Udv/dx)/V²

Let u   = a

v = x+b

Note that differential of a constant is zero

du/dx = 0

dv/dx = 1

Substitute

dy/dx = (x+b)0 - a (1)/(x+b)²

dy/dx = 0 - a/(x+b)²

dy/dx = -a/(x+b)²

The bake sale raised $60.00. If each cookie cost $0.75, how many cookies were sold
Pls help help help.

Answers

Hello!

[tex]\large\boxed{80 \text{ cookies}}[/tex]

To find the amount of cookies sold, we will need to divide the cost of each cookie from the total raised. Therefore:

Let c = cookies sold

60 = 0.75c

Divide both sides by 0.75:

60 / 0.75 = c

c = 80 cookies.

you have decided to give your best friend a bag of
red and green marbles for his birthday. your friend
likes green marbles better than red ones, so the
bag has twice as many green marbles as red. The
label on the bag says it lcontains a total of 84 marbles.
How many green marbles are in the bag? Write a
System of equations for this problem. Then solve the
problem using any method you like. Be sure to check
your solutions

Answers

Answer:

There are 28 red marbles and 56 green marbles in the bag.

Step-by-step explanation:

Let's define:

R = number of red marbles in the bag.

G = number of green marbles in the bag.

We know that:

"There is a total of 84 marbles in the bag"

Then we can write this as:

R + G = 84

"The bag has twice as many green marbles as red marbles"

Then:

G = 2*R

So we have two equations:

R + G = 84

G = 2*R

This is the system of equations we need to solve.

To solve this, we usually start by isolating one of the variables in one of the equations, here we can see that G is already isolated in the second equation, then we can ignore the first step.

Now that we have an isolated variable, we can replace it in the other equation, then we can replace the second equation in the first one to get:

R + G = 84

R + (2*R) = 84

3*R = 84

R = 84/3 = 28

This means that there are 28 red marbles in the bag.

Now we can use the equation:

G = 2*R

To find the number of green marbles, where we need to replace R y 28, then we get:

G = 2*28 = 56

Which means that there are 56 green marbles.

The same honey is sold in two different size jars.
Small Jar
Large Jar
510g for £4.39
380g for £3.12
By considering the amount of honey per penny, work out
which jar is the best value for money.
Working must be shown.

Answers

Answer:

Large Jar:

510/439= 1.16p per 1g of honey

Small Jar:

380/312= 1.21p per 1g of honey

Therefore the Small Jar is best value for amount of honey per penny

Answer:2) B. 303) B. a triangle with measurements of 2, 3 and 5 inches .

Step-by-step explanation:

2) 85° = (3x - 5)° [Vertically Opposite Angles]

=> 3x - 5 = 85

=> 3x = 85 + 5

=> 3x = 90

[tex] = > x = \frac{90}{3} [/tex]

=> x = 30

Hence,

Here,

2 + 3 = 5.

And according to Triangle Inequality Property measurement of any two sides of the triangle should be greater than the third side.
