Answer:

Step-by-step explanation:

24=c

Answer:

7.2

Step-by-step explanation:

To reach point D from point C, you need to add 4 to the x-value of point C and take away 6 from the y-value. These numbers are the sides of the hypothetical triangle.

The Pythagorean Theorem states that [tex]a^2+b^2=c^2[/tex]. If we plug the side lengths in for a and b, we get [tex]4^2 + 6^2 = c^2[/tex]. This can be simplified to [tex]16+36=c^2[/tex], or [tex]52 = c^2[/tex]. If we root both sides, we find that c is equal to [tex]\sqrt{52}[/tex], which is slightly more than 7, at around 7.2.

Answer:

12.25

Step-by-step explanation:

Solution for What is 35 percent of 35:

35 percent *35 =

( 35:100)*35 =

( 35*35):100 =

1225:100 = 12.25

Now we have: 35 percent of 35 = 12.25

Question: What is 35 percent of 35?

Percentage solution with steps:

Step 1: Our output value is 35.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above, 35 = 100%

Step 4: Similarly, x = 35%

Step 5: This results in a pair of simple equations:

35 = 100% (2)

x = 35% (2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have

[tex]\frac{35}{x} =\frac{100}{35}[/tex] (with % for 100 and 35)

Step 7: Again, the reciprocal of both sides gives

[tex]\frac{x}{35} =\frac{35}{100}[/tex]

⇒ x=12.25

Therefore, 35% of 35  is 12.25

Answer:

x=55

Step-by-step explanation:

The angles are corresponding angles and corresponding angles are equal

3x-60 = x+50

Subtract x from each side

3x-60-x = x+50-x

2x-60 =50

Add 60 to each side

2x-60+60=50+60

2x=110

Divide by 2

2x/2 =100/2

x =55

Answer:

One number is 5 and the other is 1.

Step-by-step explanation:

Let the numbers be x and y.  Then x + y = 6 and x - y = 4.  We must solve this system of equations:

x + y = 6

x - y = 4

Combining these equations temporarily eliminates y:

x + y = 6

x - y = 4

--------------

2x     = 10

Then x = 5.  Since x - y = 4,

5 - y = 4

and so y must be 1.

The solution is (5, 1).  One number is 5 and the other is 1.

Answer:

9.06 units (3 s.f.)

Step-by-step explanation:

[tex]\boxed{distance \: between \: 2 \: points = \sqrt{(y1 - y2)^{2} + {(x1 - x2)}^{2} } }[/tex]

☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate.

Distance between (-1, -6) and (8, -7)

[tex] = \sqrt{[- 7 - ( - 6)]^{2} + [8 - ( - 1)]^{2} } [/tex]

[tex] = \sqrt{ {( - 7 + 6)}^{2} + (8 + 1) {}^{2} } [/tex]

[tex] = \sqrt{( - 1)^{2} + {9}^{2} } [/tex]

[tex] = \sqrt{1 + 81} [/tex]

[tex] = \sqrt{82} [/tex]

= 9.06 units (3 s.f.)

Answer:

We fail to reject the Null and conclude that the standard deviation of the contributions of all sanitation workers is not greater than that of all workers living in the city.

Step-by-step explanation:

σ = 1.40 ; σ² = 1.40² = 1.96

H0 : σ² = 1.96

H0 : σ² > 1.96

Given that:

Sample size, n = 12

Population Standard deviation, σ = 1.40

Sample standard deviation, s = 1.75

α = 0.01

The test statistic :

χ² = [(n-1)s²] ÷ σ²

χ² = [(12 - 1) * 1.75²] ÷ 1.40²

χ² = (11 * 3.0625) ÷ 1.96

χ² = 33.6875 / 1.96

χ² = 17.1875

χ² = 17.19

Using the Pvalue from Chisquare score calculator;

df = n - 1 ; 12 - 1 = 11

Pvalue ; χ²(17.19, 11) = 0.10238

Since Pvalue > α ; We fail to reject the Null and conclude that the standard deviation of the contributions of all sanitation workers is not greater than that of all workers living in the city.

Answer:

this should explain your answer.

Answer:

Step-by-step explanation:

Each term in the sequence is 4 less than the previous term.  That indicates an arithmetic sequence, which has the form a(n) = a(1) + d(n -1), where d is the common difference.  Here the common difference is -4, and so the appropriate sequence is

a(n) = 14 - 4(n - 1)

Answer:

70, 130

Step-by-step explanation:

Just took the Mastery test on PLATO and this answer was correct.

Answer:

136

Step-by-step explanation:

First you need to know that there are 2 triangles in the image.

One triangle (the smaller one) has sides that measure 119 (the side) and 56 (the bottom).

The other triangle (the bigger one) has sides that measure 119 + ? (the side) and 120 (the bottom).

Let's replace the 119 + ? with an x so that the entire side length of the big triangle measures x.

1. Make a proportion using ratios. For the ratios of each triangle, we can do side over bottom lengths and then set them equal to each other.

119  =    x              sides

56        120            bottoms

2. You can cross multiply, or just solve for x.

119*120= 14280

14280/56= 255

3. Then subtract the total length minus 119 to find the question mark

255 - 119 = 136

Answer:

Bc=20

Step-by-step explanation:

Sin61=BC/AC=BC/23

BC=23sin61=20

Step-by-step explanation:

w(idth) = 2.5 inches for both boxes

h(eight) = 10 inches for both boxes

l(ength)l(arge) = 8 inches

l(ength)s(mall) = 75% of ll (=> of 8 inches)

=> ls = 8 × 75/100 = 2 × 75/25 = 2 × 3 = 6 inches

vl (volume large) = 8 × 2.5 × 10 = 200 inches³

vs (volume small) = 6 × 2.5 × 10 = 150 inches³

the difference of these two volumes is 50 inches³

the units to be used is cubic inches (inches³). we are talking about volumes. not lengths (inches), not areas (inches²).

the reason - for a volume we need to multiply 3 lengths (measured in simple inches). so, inch multiplied by inch is inch². this multiplied by inch again is then inch³.

Step-by-step explanation:

Corresponding angles are congruent, so x = 43! I hope this helps, have a good day!

Answer and Step-by-step explanation:

First, add x to both sides.

5ba = x + y

Now, divide both sides by 5a.

[tex]b = \frac{x+ y}{5a}[/tex] is the answer.

Answer:

i think that the answer is 149

Answer:

2

Step-by-step explanation:

Answer:

9.4 x 11 = 103.4

15 + 7 = 22, 22 x 5 = 110, 110 divided by 2 = 55

55 x 2 (since there are two trapezoids) = 110

5 x 11 = 55

7 x 11 = 77

15 x 11 = 165

Now we add all the areas up:

103.4 + 110 + 55 + 77 + 165 = 510.4 square feet2 is your answer.

Answer:

AC ≈ 10.3

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan48° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{AC}{9.3}[/tex] ( multiply both sides by 9.3 )

9.3 × tan48° = AC , then

AC ≈ 10.3 ( to 3 sf )
