Answer:

The cost of materials is $32.

Step-by-step explanation:

You can solve this in a simple manner:

115 = 2.5m + 35

115-35 = 2.5m

80 = 2.5m

m = 32

You can check your answer by putting 32 back into the equation(P=2.5m+35) and you should get 115(which is price of bracelet)

Answer:

26 people

Step-by-step explanation:

15z +80 = 478

15z = total cost of the people

80 = cost of room

478 = budget

15z + 80 = 478

Subtract 80 from both sides

15z = 398

z = 26.53333

You can't have a decimal person

z = 26

The indicated probability of  the normal distribution is 0.9332

The natural and social sciences frequently utilize normal distributions to describe real-valued random variables which distributions are unknown, which is why normal distributions are essential in statistics.

In the given normal distribution:

mean = 8 and standard deviation = 2

The indicated probability is given by P(7 ≤ x ≤ 11)

The z score of the distribution is given by

Z = ( 11 - 8 ) ÷ 2 = 1.5

From the z-score we can calculate the probability :

P(7 ≤ x ≤ 11) = 0.9332

Therefore the indicated probability is 0.9332

The fraction of the money the old girl gets is 7x/22 and the oldest gets 5x/11.

Given,

Oldest gets 5/11 of the share.

The older gets 7/12 of the remainder.

Solution:

Let x be the total amount.

Oldest share = 5/11*x

= 5x/11

Older share =( x - 5/11*x)*7/12

= (11x-5x/11)*7/12

= 6x/11*7/12

= 42x/132

= 21x/66

=7x/22

∠M

Step-by-step explanation:

∠M is the only vertex that does not already have an indicated angle. There are three vertexes, being 90° at ∠K (the box-like figure means it is a right angle, therefore 90°) , 61° at ∠N , and ∠M, which does not have a given angle.

After calculating the given fractions, we have to find that Maggie is left $500 and therefore she saved $500.

Mathematically, a fraction is represented as a numerical value that identifies a portion of a whole. A fraction is a portion or section of any amount that makes up a whole, where a whole can be any number, a certain amount, or an object.

Use this example to help us understand this idea. Pizza is divided into 8 equal pieces in the following illustration. Now, if we want to express one particular piece of the pizza, we can do so by using the notation 1/8, which indicates that we are speaking of one piece out of a total of 8 equally sized pieces.

It means one in eight equally sized portions. It can also be read as follows:

1/8th, or 1 by 8

Given that Maggie has $960

She spends 1/4 of the money on a mountain bike that gives

⇒ 960 - (960 × 1/4)

⇒ 960 - 240

= $720

And the she uses 1/6 of the remainder on bicycle clothing and accessories that gives

⇒ 720 - (720 × 1/6)

⇒ 720 -  120

= $500

Thus, she is left $500 dollar and therefore she saved $500.

Solving the simultaneous equation gives x as 2 and y as 3

From the information given, we have the equations as;

Now, substitute the value of y as x + 1 in equation (2) into the equation (1)

We have;

x² + (x + 1)² = 13

expand the bracket

x² + (x + 1)(x+1) = 13

x² + x² + x + x +1 = 13

collect like terms

2x² + 2x + 1 - 13 = 0

2x² + 2x - 12 = 0

Factorize the equation

2x² + 6x - 4x - 12 = 0

Factor the common terms

2x(x + 3) - 4(x + 3) = 0

2x - 4 = 0

x = 2

x = -3

Substitute x as 2 into equation (2)

y = x + 1

y = 2 + 1

y = 3

Hence, the values are 2 and 3

Answer: The answer would be D. 20  Because u plug 3 in for x so F(x)= 9+9+2

Step-by-step explanation:

Given f(x) and g(x) = f(x) + k, from the graph, we can determine the value of k as 4 units.

In the question,

Given f(x) and g(x) = f(x) + k

From the graph, we can say that there is a shift of 4 units up between f(x) and g(x).

The given lines are parallel lines, so their slopes will be the equal but intercepts will be different for both the lines.

The y-intercept of f(x) = -3 and that of g(x) = 1

Hence, the difference between the intercepts when calculated is (1 -(-3))  = 4.

Therefore, g(x) = f(x) + 4

So, the value of k is 4.

190 ÷5x

×=38

Answer:

a)  x = 38

b)  61° and 119°

Step-by-step explanation:

Same-side Exterior Angles Theorem

When two parallel lines are intersected by a transversal, the angles that are exterior to the parallel lines and on the same side of the transversal line are supplementary (sum to 180°).

Using the Same-side Exterior Angles Theorem, equate the sum of the two angles to 180° and solve for x:

⇒ (2x - 15)° + (3x + 5)° = 180°

⇒ 2x - 15 + 3x + 5 = 180

⇒ 5x - 10 = 180

⇒ 5x = 190

⇒ x = 38

Substitute the found value of x from part (a) into the expressions for each angle:

⇒ (2x - 15)°

⇒ (2(38) - 15)°

⇒ (76 - 15)°

⇒ 61°

⇒ (3x + 5)°

⇒ (3(38) + 5)°

⇒ (114 + 5)°

⇒ 119°

Therefore, the two angles are 61° and 119°.

Answer:

This relation is NOT a function

Step-by-step explanation:

As you see in the attached image, the x value of 1 has 2 different points assigned to it. This relation would fail the vertical line test, therefore it is not a function.

Key words:
Relation: Any graph

Function: A relation that has 1 y value for every x value

Vertical line test: An imaginary line drawn on a relation/function to test if it is a function. (in some cases, like this relation, you will see right away from the placement of the points that it is not a function)

The slope is -0.1 starting at 3.9, the GPA will decrease by 0.1 for each text sent in class.

Here we have to find the slope.

The equation given is:

y = 3.9 - 0.1x

As we know that the equation of a line is:

y = mx + c

Therefore we get that the slope is m = -0.1

Starting at 3.9 the GPA will decrease by 0.1 for every text sent in class ( for y = mx + b, a is the slope which is the coefficient of x)

Because the slope is less than 0, it is decreasing.

Therefore the slope is -0.1 and there is a decrease in GPA of 0.1.
