Answer:

the large boxes weigh 40 pounds and the smaller boxes weigh 30 pounds

Step-by-step explanation:

define variables:

b is the weight of large boxes and s is the weight of small boxes. you can create two equations to represent what you know:

b + s = 70 (the weight of one large box and one small box is 70 pounds)

60b+ 55s = 4050 (the total weight of the 60 large boxes and the 55 small boxes is 4050)

then by making one of the equations equal to a variable, you can use substitution to solve.

s = 70 - b

so 60b + 55s = 4050 now becomes:

60b + 55(70 - b) = 4050, and next you solve for b

60b + 3850 - 55b = 4050

5b = 200

b = 40.

now you know that the large boxes weigh 40 pounds. to solve for the small box weight, you plug in b in either equation. i am going to choose the first once since it's fewer steps

b + s = 70 -> 40 + s = 70

s = 30

and now you know that the smaller boxes weigh 30 pounds.

The value of c in the missing triangle is 39

The side c can be found using Pythagoras theorem.

Therefore,

c² = a² + b²

c² = 36² + 15²

c² = 1296 + 225

c = √1521

c = 39

Answer:

ok so use the degrees

Step-by-step explanation:

x should be 8 + 17 and then multiply the 110 degrees by 8 + 17

Answer:

x = 6

The marked angle is 110°

Step-by-step explanation:

See how there are 8 angles in this type of image. The angles either are EQUAL, or they ADD UP TO 180°. It's just two numbers for the degrees of these angles. Four of them are the same and the other four are the same.

In your question the 8 + 17x = 110°

Solve.

Subtract 8.

17x = 102

Divide by 17.

x = 6

If your question says find the measure of the angle it is 110°, if you are to find x, then x = 6.

Jfyi, four of these angles are 110°. The other four are 70°.

Using the combination formula, it is found that 84 different groups of 6 people are possible from the 9 remaining friends.

The order in which the friends are chosen is not important, hence the combination formula is used to solve this question.

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this problem, 6 friends are chosen from a set of 9, hence:

[tex]C_{9,6} = \frac{9!}{6!3!} = 84[/tex]

84 different groups of 6 people are possible from the 9 remaining friends.

Step-by-step explanation:

If the raffle has 200 tickets total, then about 50 tickets will be in the dining out raffle.

An equation is an expression that shows the relationship between two or more numbers and variables.

From the diagram:

Percentage of dinner out = 65% - 40% = 25%

For 200 total tickets:

Number of dinning out raffle = 25% of 200 = 0.25 * 200 = 50 ticket

If the raffle has 200 tickets total, then about 50 tickets will be in the dining out raffle.

[tex]\boxed{\tt \pink{Solution}}[/tex]

To find volume of Cylinder first we should know radius of Cylinder. We can get radius by diameter using this formula:-

[tex]\boxed{\rm Diameter = 2 radius}[/tex]

[tex]\\\\[/tex]

[tex]\hookrightarrow\sf Diameter = 2 radius[/tex]

[tex]\\[/tex]

[tex]\hookrightarrow\sf 20= 2 radius[/tex]

[tex]\\[/tex]

[tex]\hookrightarrow\sf \dfrac{20}{2}= radius[/tex]

[tex]\\[/tex]

[tex]\hookrightarrow\sf \dfrac{2\times10}{2}= radius[/tex]

[tex]\\[/tex]

[tex]\hookrightarrow \sf \dfrac{\cancel2\times10}{\cancel2}= radius[/tex]

[tex]\\[/tex]

[tex]\hookrightarrow \sf \dfrac{1\times10}{1}= radius[/tex]

[tex]\\[/tex]

[tex]\hookrightarrow \sf 10= radius[/tex]

[tex]\\[/tex]

[tex]\hookrightarrow \bf radius = \pmb{\blue{10 cm}}[/tex]

[tex]\\\\[/tex]

Now Finally Let's find volume of Cylinder.

we know:-

[tex]\boxed{\rm Volume ~ of ~ Cylinder = \pi radius^2 \times height}[/tex]

[tex]\\\\[/tex]

So:-

[tex]\dashrightarrow\sf Volume ~of ~Cylinder = \pi radius^2\times height\\[/tex]

[tex]\\\\[/tex]

[tex]\dashrightarrow\sf Volume ~of ~Cylinder = \pi (10)^2\times 5\\[/tex]

[tex]\\\\[/tex]

[tex]\dashrightarrow\sf Volume ~of ~Cylinder = \pi 10\times10\times5\\[/tex]

[tex]\\\\[/tex]

[tex]\dashrightarrow\sf Volume ~of ~Cylinder = \pi 100\times5\\[/tex]
