Answers

Answer 1

Answer:

n = 0.8

Step-by-step explanation:

3n + 3 = 5.4

-3 form each side

3n=2.4

÷3 for each side

n=0.8

Answer 2

Answer:

0.8

Step-by-step explanation:

3(n+1)=5.4

Divide both sides by 3

3(n+1)/3 = 5.4/3

simplify

n+1=1.8

subtract 1 from both sides

n+1-1=1.8-1

N=0.8

Answers

Answer:

the first option is the answer, r = √6

Step-by-step explanation:

[tex]hypotenuse = \sqrt{opposite {}^{2} + adjacent {}^{2} } [/tex]

hypotenuse = q = √12

adjacent = p = √6

opposite = r

substitute the values into the hypotenuse formula

[tex]q = \sqrt{r {}^{2} + p {}^{2} } [/tex]

[tex] \sqrt{12} = \sqrt{r {}^{2} + ( \sqrt{6} ) {}^{2} } [/tex]

[tex]( \sqrt{12} ) {}^{2} = r {}^{2} +6[/tex]

[tex]12 = r {}^{2} + 6[/tex]

[tex]12 - 6 = r {}^{2} [/tex]

[tex]6 = r {}^{2} [/tex]

[tex] \sqrt{6} = r[/tex]

[tex]r = \sqrt{6} [/tex]

all angles inside a triangle add up to equal 180, the inside angle at R is 75 degrees, the TP line is obviously a 180 degree angle, because it's just a straight line, so you subtract 75 from 180 to get 105

Find the area under the curve y = 1/x^2 between the ordinates x=1 and x=5

Answers

Answer:

The area is -6/5 units

Step-by-step explanation:

We start by integrating the curve equation

1/x^2 = x^-2

So the integration will be;

x^-2+1/-2 + 1 = -1/x + k

So we have the area as;

-1/5 -1 = (-1 - 5)/5 = -6/5

Α. ΑΑ

D. Not similar

Answers

Answer:

not similar

Step-by-step explanation:

similar means proportional

1, 1, and 0.5 are not proportional to 3.5, 3, and 2.25

As the two side lengths of the smaller triangle is the same but the ratio of those side in a larger triangle and the smaller triangle is different they are, D. Not similar.

What is congruency?

We know two similar planer figures are congruent when we have sides or angles or both that are the same as the corresponding sides or angles or both.

We know two triangles are similar if the ratios of their corresponding sides are equal.

The larger triangle has sides 3, 3.5, and 2.25.

And the smaller triangle has sides 1, 1, 0.5.

As the smaller triangle has side lengths 1, 1, and the ratio of the sides of the larger triangle and the smaller triangle is (2 + 1)/1 and (2.5 + 1)/1 which is equal to 3/1 and 3.5/1 3 and 3.5 but the smaller side has 1 and 1, therefore, they are not similar.

Mt. Calvary's budget for a swing set to be built for the Children's Church is $900. If the cost of the swing set should be at least one-fourth as much as the fort, how much can be spent on the fort and still build the swing set?

Answers

Answer:

[tex]Amount = \$4500[/tex]

Step-by-step explanation:

Represent Swing Set with S and Fort with F

Given

[tex]S = \$900[/tex]

[tex]S = \frac{1}{4}\ of\ F[/tex]  --- S = one-fourth of F

Required

Determine the amount spent on both

Substitute 900 for S in [tex]S = \frac{1}{4}\ of\ F[/tex]

[tex]\$900 = \frac{1}{4} * F[/tex]

Multiply both sides by 4

[tex]4 * \$900 = \frac{1}{4} * F * 4[/tex]

[tex]4 * \$900 = F[/tex]

[tex]\$3600= F[/tex]

[tex]F = \$3600[/tex]

The total amount to be spent it:

[tex]Amount = F + S[/tex]

[tex]Amount = \$3600 + \$900[/tex]

[tex]Amount = \$4500[/tex]
