please help.I don’t understand

Answers

Answer 1

Answer:

y=13 degrees

Step-by-step explanation:

This is an isosceles triangle, we know this because NO and NM are equal.

In an isosceles triangle, the base angles are congruent. In this case, they are angle NOM and angle NMO.

We also know that the sum of the interior angles of a triangle are equal to 180.

With this information, we can make an equation by gathering all the interior angles:

8y+2(3y-1)=180

Solve for y.

8y+6y-2=180

14y-2=180

14y=182

y=13

Answer:

x = - 2

Step-by-step explanation:

The axis of symmetry passes through the vertex, is a vertical line with equation equal to the x- coordinate of the vertex, that is

equation of axis of symmetry is x = 1

The zeros are equidistant from the axis of symmetry, on either side

x = 4 is a zero and is 3 units to the right of x = 1, so

3 units to the left of x = 1 is 1 - 3 = - 2

The other zero is therefore x = - 2

Find the area of the shaded sector below.

Answers

Answer:

9.07571212

Step-by-step explanation:

To solve this we first need to find the area of the circle, r squared times pi

4 x 4 x pi = 50.2654825

Now we multiply this by 65/360, 50.2654825 x 65/360 = 9.07571212

The shaded sector covers 9.07571212 square inches.

The Royal Fruit Company produces two types of fruit drinks. The first type is 30% pure fruit juice, and the second type is 80% pure fruit juice. The company is attempting to produce a fruit drink that contains 35% pure fruit juice. How many pints of each of the two existing types of drink must be used to make 90 pints of a mixture that is 35% pure fruit juice?

Answers

Answer: I- 81 pints, II-9 pints

Step-by-step explanation:

Given

The first type of juice has 30% pure Juice

The second type of juice has 80% pure Juice

The final mixture has 95 pints of 35% pure juice

Suppose we take x pints from the first Juice

So, the second Juice contributes 90-x

for 35% content

[tex]\Rightarrow 35=\dfrac{x\times 30+(90-x)80}{90}\\\\\Rightarrow 3150=30x+7200-80x\\\\\Rightarrow 50x=4050\\\Rightarrow x=81\ \text{pints}[/tex]

First contributes 81 pints. second contributes 9 pints

MAD (Mean absolute deviation) is always a negative number

True or False

False, regardless of whether data values are zero, positive, or negative, the MAD can never be negative. This is because the MAD is calculated by finding absolute values of the deviations (or differences) from the mean, and then taking the average (or mean) of these absolute values.

Step-by-step explanation:

This is a stem and leaf plot, so the stem represents the first digit, while the leaf is the last digit.

Stem# Leaf#

The first stem is 0, with a leaf of 4. Therefore,

04 = 4

The last stem is 5, with 2 leaves: 6 and 7. We want to find the largest number, so we will use 7.

The range is the difference between the largest and smallest number. The largest number is 57 and the smallest is 4.

Range= largest-smallest Range= 57-4=53

The range is 53.

The number of $15 DVDs and $12 DVDs at an electronics store will be 3 and 5, respectively.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

At a hardware store, DVDs are at a bargain. A few DVDs cost $15.00 each and some expenses $12.00 each. Bart bought 8 DVDs and spent a sum of $105.00.

Let 'x' be the number of $15 DVDs and 'y' be the number of $12 DVDs. Then the equations are given as,

x + y = 8 ...1

15x + 12y = 105 ...2

From equations 1 and 2, then we have

15x + 12(8 - x) = 105

15x + 96 - 12x = 105

3x = 9

x = 3

Then the value of y is given as,

y = 8 - 3

y = 5

The number of $15 DVDs and $12 DVDs at an electronics store will be 3 and 5, respectively.

4x^2+2x-1=0 in quaratic equations

Answers

Answer:

Step-by-step explanation:

"quaratic" should be "quadratic."

The coefficients of this quadratic are 4, 2 and -1. Thus, the discriminant is

b^2 - 4ac, or here, 4 - 4(4)(-1) = 20

Since the discriminant is positive, our quadratic has two real, different roots.

-2 ± (√4)(√5)

The roots are: x = ---------------------

2(4)

-1 ± √5

This reduces to x = ---------------
