Answer: ↓↓

Step-by-step explanation:

∠ABF and m∠60° are complementary since they form a right angle.

∠ABF + 60 = 90

∠ABF = 30°

∠ABF and ∠CBD are vertical angles so they're congruent.

∠CBD ≅ ∠ABF

∠CBD ≅ 30

∠CBD = 30°

∠ABC and ∠CBD are linear pair so they're supplementary.

∠ABC + ∠CBD = 180°

∠ABC + 30 = 180

∠ABC = 150

Answer:

k = 16/33

Step-by-step explanation:

Determine k so that 2/3,k and 5/8k are the three consecutive terms of an a.p

k - 2/3 = 5/8k - k

3k-2/3 = 5k-8k/8

Cross product

(3k-2)(8) = (3)(5k-8k)

24k - 16 = 15k - 24k

24k - 16 = -9k

24k + 9k = 16

33k = 16

k = 16/33

(b) [tex]\$24,169.60[/tex]

Step-by-step explanation:

Given:  Cost of car is [tex]\$22,346.16[/tex]

            Sales tax is [tex]7.6\%[/tex]    

             The license and title  charges are [tex]\$125.13[/tex]

To find: The amount that the credit union will finance.

Solution:

We have,  

Cost of car[tex]=\$22,346.16[/tex]  

Sales tax is [tex]7.6\%[/tex] of [tex]\$22,346.16[/tex]

Therefore,  

sales tax [tex]=\frac{7.6}{100}\times22,346.16=\$1698.31[/tex]

The license and title  charges [tex]=\$125.13[/tex]

Now, the amount that the credit union will finance is

cost of car[tex]+[/tex]sales tax[tex]+[/tex]the license and title  charges

[tex]=\$22346.16+\$1698.31+\$125.13[/tex]

[tex]=\$24,169.60[/tex]

Hence, the amount that the credit union will finance is [tex]\$24,169.60[/tex].

So, (b) [tex]\$24,169.60[/tex] is correct.

Step-by-step explanation:

Let x be the height of the screen.

Using Pythagoras' Theorem,

we have x² + 16² = 24².

Therefore x² = 24² - 16² = 320,

x = √320 = 8√5 in.

The height of the screen is 8√5 inches.

Answer:

Step-by-step explanation:

Let the present age of Alicia be x

Let the present age of her brother be y

Three years ago;

Alicia age = x - 3

Her brother's age = y - 3

If three years ago Alicia was twice as old as her brother Carlos, then;

X - 3 = 2(Y-3)

x-3 = 2y - 6

x = 2y - 3 ...1

In two years time;

Alicias age = x+2

Her brother's age = y +2

If in two more years Alicia will be just 50% older than Carlos, then;

x+2 = y + 2 + (0.5(y+2))

x+2 = y+2 + 0.5y + 1

x+2 = 1.5y+3

x = 1.5y + 1 ...2

Equating 1 and 2;

2y - 3 = 1.5y + 1

2y - 1.5y = 1+3

0.5y = 4

y = 4/0.5

y = 8

Since x = 2y-3

x = 2(8) - 3

x = 16-3

x = 13

Hence Alicia will be 13 years old today

Time taken to cover 10 miles = 80 minutes

Step-by-step explanation:

Given:

Ratio [Number of minutes : Number of miles runs] = 24:3

Find:

Time taken to cover 10 miles

Computation:

Number of minutes/Number of miles runs = Time taken to cover 10 miles / 10

24/3 = Time taken to cover 10 miles / 10

Time taken to cover 10 miles = 80 minutes

Answer: Assuming it means slope-intercept, the answer would be y=-2x+9

y = -2x + 9 is the equation of the line given in the graph.

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given a graph of the line, Where we can see that the line passes through the coordinates (0, 9) and (1, 7)

From the slope-intercept formula of a line:

y = mx +c

Where m is the slope

And c is the value of y at x =0

Thus in our case,

c = 9

and slope m = (y - y )/(x - x)

m = (7-9)/(1-0)

m = -2

so, the equation of the line:

y = -2x + 9

Therefore, the equation of the line in the given Graph is y = -2x + 9.

Given that,

velocity, v = 7.8 ft/s

Radius, r = 1.25 ft

To find,

a. What is the acceleration of the bucket?

b. What is the velocity if the acceleration is 25 ft/sec²?

Solution,

(a) The centripetal acceleration is given by :

[tex]a=\dfrac{v^2}{r}[/tex]

Put v = 7.8 ft/s and r = 1.25 ft

[tex]a=\dfrac{(7.8)^2}{1.25}\\\\=48.672\ ft/s^2[/tex]

(b) Put a = 25 ft/s² to find velocity.

[tex]v=\sqrt{ar} \\\\v=\sqrt{25\times 1.25} \\\\v=5.59\ ft/s[/tex]

Hence, this is the required solution.

Answer:

The length of [tex]\overline {FH}[/tex] is;

D. 38 units

Step-by-step explanation:

The given parameters are;

The type of the given quadrilateral FGHI = Rectangle

The diagonals of the quadrilateral = [tex]\overline {FH}[/tex] and [tex]\overline {GI}[/tex]

The length of IE = 3·x + 4

The length of EG = 5·x - 6

We have from segment addition postulate, [tex]\overline {GI}[/tex] = IE + EG

The properties of a rectangle includes;

1) Each diagonal bisects the other diagonal into two

Therefore,  [tex]\overline {FH}[/tex] bisects [tex]\overline {GI}[/tex], into two equal parts, from which we have;

IE = EG

[tex]\overline {GI}[/tex] = IE + EG

3·x + 4 = 5·x - 6

4 + 6 = 5·x - 3·x = 2·x

10 = 2·x

∴ x = 10/2 = 5

From which we have;

IE = 3·x + 4 = 3 × 5 + 4 = 19 units

EG = 5·x - 6 = 5 × 5 - 6 = 19 units

[tex]\overline {GI}[/tex] = IE + EG = 19 + 19 = 38 units

[tex]\overline {GI}[/tex] = 38 units

2) The lengths of the two diagonals are equal. Therefore, the length of segment [tex]\overline {FH}[/tex] is equal to the length of segment [tex]\overline {GI}[/tex]

Mathematically, we have;

[tex]\overline {FH}[/tex] = [tex]\overline {GI}[/tex] = 38 units

∴ [tex]\overline {FH}[/tex] = 38 units.

Answer:

16÷5 is the division problem

Answer:

y = - 3, x = 8

Step-by-step explanation:

x - y = 11, x = 11 + y

Lets solve this equation with substitution: 3x + 10y = - 6

3(11+y)+10y=-6

33+3y+10y=-6

13y=-39

y = - 3

x - (-3) = 11

x + 3 = 11

x = 8

Answer:

use the first equation and solve for the variables

Step-by-step explanation:

for example, to solve for x add y on both sides x=11+y and substitute that to the equation

3(11+y)+10y=-6

that should give you -3

then go back to the equation x=11+y

x=11+(-3)

x=8

Answer: Choice A.  [tex](-\infty, \infty)[/tex]

This is the same as saying the set of all real numbers.

There are no restrictions to put on the domain, so there are no values to avoid. This is because there are gaps, jumps, or holes in the graph. It's one continuous single curve.

This curve stretches forever to the left and right. As it goes left, it moves up (rises to the left). As it moves right, it goes downhill (it falls to the right). Saying "rises to the left and falls to the right" is an informal way to describe the end behavior. The actual specific end behavior doesn't matter. What matters is both left and right sides go on forever.

A domain of the set of all real numbers means we can plug in any real number for x, and get some output for y, which is part of the range.

One way we can describe the set of all real numbers in terms of an inequality is to write [tex]-\infty < x < \infty[/tex] meaning that x is between negative and positive infinity, ie x is anything you want. The inequality [tex]-\infty < x < \infty[/tex] converts to the interval notation [tex](-\infty, \infty)[/tex]. Interval notation is a compact way of writing compound inequalities.
