Calculate the variance.

Answer:

x = 4

Step-by-step explanation:

the given figure is of an isoceles triangle.

The two angles opposite are congruent(i.e78 degrees) .

That is the sides opposite to them are also congruent.

I. e 4x + 23 = 10x - 1

I. e 4x - 10x = -1 -23

I. e -6x = -24

I. e -x. = -24/6

Dividing by 6 to 24 we get,

-x = -4

therefore by removing the minus sign from both the sides,

the answer comes x = 4

Answer:

$745,460.8

Step-by-step explanation:

2.8/100 × 3827 = $107.16

monthly = 1/12

[tex]p = \frac{100 \times i}{rt} = \frac{100 \times 107.16}{2.8 \times \frac{1}{12} } = \frac{10716}{0.23} \\ = 46591.3[/tex]

$46,591.3 in 1year

16 years; $46,591.3 × 16 = $745,460.8

Answer:

60 degrees

Step-by-step explanation:

There is an alternate angle, which would make the other angle on the same horizontal line as x 120 degrees, thus leaving 60 degrees.

Answer: [tex]\overline{AC}=[/tex] 12.5

Step-by-step explanation: The triangle ABC and its altitude [tex]\overline{BD}[/tex] is represented in the figure below.

Altitude is a segment of line that link a vertex and the opposite side, forming a right angle.

So, because of [tex]\overline{BD}[/tex], now we have two similar triangles, which means that ratios of corresponding sides are equal:

[tex]\frac{\overline{BD}}{\overline{BC}} =\frac{\overline{AD}}{\overline{BD}}[/tex]

[tex]\overline{BD}^{2}=\overline{BC}.\overline{AD}[/tex] (1)

This is always true for a right triangle and a altitude drawn to the hypotenuse.

Triangle BDC is also right triangle. So, we can use Pythagorean theorem to determine the missing side.

[tex]\overline{BC}^{2}=\overline{CD}^{2}+\overline{BD}^{2}[/tex]

[tex]\overline{BD}^{2}=\overline{BC}^{2}-\overline{CD}^{2}[/tex] (2)

Substituting (2) into (1):

[tex]\overline{BC}^{2}-\overline{CD}^{2}=\overline{BC}.\overline{AD}[/tex]

We want to find f, so:

[tex]\overline{AD}=\frac{\overline{BC}^{2}-\overline{CD}^{2}}{\overline{BC}}[/tex]

[tex]f=\frac{10^{2}-5^{2}}{10}[/tex]

f = 7.5

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

[tex]\overline{AC}=f+5[/tex]

[tex]\overline{AC}=7.5+5[/tex]

[tex]\overline{AC}=12.5[/tex]

The length of the hypotenuse of triangle ABC is 12.5 units.

Answer:2/6 i might be wrong but whats the answer choices?

Step-by-step explanation:

Answer:

Step-by-step explanation:

You can see that (0,4) and (1,1) are points on the line. Use their coordinates to determine the slope of the line.

slope = (difference of y-coordinates)/(difference of x-coordinates)

= (1-4)/(1-0)

= -3

Answer:

[tex]0.6875[/tex]  OR:  [tex]0.7[/tex]

Step-by-step explanation:

[tex]0.6875\\0.688\\0.69\\0.7[/tex]

Step-by-step explanation:

the first one if you are solving for x it will be x=21-8y

if you are solving for y it will be y =21/8 - x/8

the second one will be if you are solving for x  x = 2 -5y/3

solving for y is y=6/5-3x/5

Complex fraction.

Hope this helped!

Answer:

its the second option thats the answer

-14

is the first one, remember 1- (-15) is like 1-15 but the you put the - on the14 so you get-14, hope this helped

Answer:

8.3

Step-by-step explanation:

Answer:

- 0.996 - Percentage increase =

- 0.996 - (12% × - 0.996) =

- 0.996 - 12% × - 0.996 =

(1 - 12%) × - 0.996 =

(100% - 12%) × - 0.996 =

88% × - 0.996 =

88 ÷ 100 × - 0.996 =

88 × - 0.996 ÷ 100 =

- 87.648 ÷ 100 =

- 0.87648 ≈

Answer:

$14 9/10

Step-by-step explanation:

Ruby had 30 dollars to spend on 3 gifts. She spent 9 7 10 dollars on gift A and 5 2 5 dollars on gift B. How much money did she have left for gift C?

From the above question,

$30 = Gift A + Gift B + Gift C

She spent 9 7/ 10 dollars on gift A and 5 2/5 dollars on gift B.

$30 = $9 7/10 + $5 2/5 + Gift C

Gift C = $30 - ( $9 7/10 + $5 2/5)

Lowest Common Denominator = 10

Gift C = $30 - $14+(7 + 4/10)

Gift C = $30 - $14+(7 + 4/10)

Gift C = $30 - $14+(11/10)

$30 - $14+(1 1/10)

$30 - $15 1/10

Gift C = $14 9/10

Therefore, the amount of money she had left for gift C is $14 9/10

Step-by-step explanation:

Answer:

The answer is 200. 50 * 4 = 200.

well if he spends $30 a week the the money should last about 3 weeks. so there wold be 3 weeks worth of money each month. so you can assume that he uses $1080 a year. and he buys fast food for 36 weeks.

Answer:

$10278

Step-by-step explanation:

Given data

P= $6000

R= 8%

T= 7 years

The compound interest formula is

A=P(1+r)^t

substitute

A=6000(1+0.08)^7

A=6000(1.08)^7

A=6000*1.713

A=$10278
