Answers

Answer:

x=9.2394

Step-by-step explanation:

It's tan we're going to use because we're looking for the opposite and we already have the angle

Therefore, x will be

Tan 57= x/6

1.5399= x/6

x= 6*1.5399

x= 9.2394

You can approximate it to the nearest whole number which will be 9

For every dollar Bennett spent on bagels, Dominic spent 25 cents less. Bennett
paid $12.50 more than Dominic. How much did they spend in the bagel store together?
(A) $37.50 (B) $50.00 (C) $87.50 (D) $90.00
(E) $92.50

Answers

Answer:

The answer is C:$87.50

Step-by-step explanation:

Ben - 1$

David - 0.75$

For each Bagel, Ben paid 0.25$ extra.

Then the total bagel Ben bought = 12.5/0.25 = 50 and the money spent = 50$

Then david spent = 3/4*50 = 37.5$

Total = 50+37.5 =$87.50

answer= 6.5y+12

distribute the 5 in the parentheses:
(-6y-3) + (15+12.5y)
(you can take away the parentheses after this step)

then add like terms together.
12.5y + (-6y) = 6.5y

Which of the b-values satisfy the following inequality? 5 < b-3
a. b=8
b. b=9
c. b=10​

Answers

Answer:

the values 9 and 10 satisfy the given inequality.

Step-by-step explanation:

Given inequality is:

[tex]5<b-3[/tex]

In order to find, which value of b satisfies the given inequality, we have to put the given values one by one in the inequality

Putting b = 8

[tex]5<8-3\\5 <5[/tex]

The inequality is not true for b=8.

Putting b=9

[tex]5<9-3\\5<6[/tex]

As the inequality is true for b=9, it satisfies the inequality.

Putting b=10

[tex]5<10-3\\5<7[/tex]

As the inequality is true for b=10, it satisfies the inequality.

Hence,

the values 9 and 10 satisfy the given inequality.

Answer:

The answer is b=9 and b=10

A square is a shape with 4 sides and all of them have to equal. Right away you can see that D is without needing to look at it. You might think that B is not because of its angle but if you turn your paper/computer to the side a bit you can there see that it is square. C and A are not because of their unequal sides. Yes, they do have four sides but they are non-equal.

3. Write the equation of the line that passes through the point (-4,5) and has a slope of 1/4

Answers

Answer:

The equation of the line that passes through the point (-4,5) and has a slope of 1/4 is: [tex]y = \frac{1}{4}x+6[/tex]

Step-by-step explanation:

Given information is:

(x,y) = (-4,5)

Slope = m = 1/4

The slope-intercept form of equation of a line is given by the formula:

[tex]y = mx+b[/tex]

Here

m is the slope of the line and b is the y-intercept.

Putting the value of slope in the equation

[tex]y = \frac{1}{4}x+b[/tex]

Now to find the y-intercept we will put the point in the equation

[tex]5 = \frac{1}{4}(-4) + b\\5 = -1+b\\b = 5+1\\b = 6[/tex]

The equation of line is:

[tex]y = \frac{1}{4}x+6[/tex]

Hence,

The equation of the line that passes through the point (-4,5) and has a slope of 1/4 is: [tex]y = \frac{1}{4}x+6[/tex]

The mistake in her steps.

Solution:

We have,

[tex]2x^4+2x^3-x^2-x[/tex]

The correct steps are shown below.

Step 1: Taking out x as common factor.

[tex]=x(2x^3+2x^2-x-1)[/tex]

Step 2: Now, taking out 2x² as common factor from first two terms (first group of terms) and -1 form last two terms (second group of terms) in the parentheses.

[tex]=x(2x^2(x+1)-1(x+1))[/tex]

Step 3: Taking out (x+1) as common factor.

[tex]=x(2x^2-1)(x+1)[/tex]

She incorrectly factored -1 from the second group of terms.

Therefore, the correct option is B.

Two of the angles in a triangle measure 51° and 25°. What must be the measure of the third angle?

Answers

Answer:

The measure of the third angle must be 104°

Step-by-step explanation:

Interior Angles of a Triangle

In any given triangle, the sum of its interior angles is 180°.

We are given the angles x=51° and y=25°. To find the third angle, z, we set up the equation:

x + y + z = 180

Solving for z:

z = 180 - x - y

Substituting:

z = 180 - 51 - 25

z = 104°

The measure of the third angle must be 104°
