Answer:

B is divisible by 5

Step-by-step explanation:

5 divisibility rule is that the number has to end in 5 or 0. Only B ends in 0, so b is the answer.

Answer:

B)270

Step-by-step explanation:

Divisibilty rule for 5: A number is divisible by 5 if the last digit is 0 or 5

Answer:

[tex]\displaystyle \cos (G)=\frac{36}{85}[/tex]

Step-by-step explanation:

Recall that cosine is the ratio of the adjacent side to the hypotenuse:

[tex]\displaystyle \cos(G)=\frac{\text{adjacent}}{\text{hypotenuse}}[/tex]

The hypotenuse is always the side opposite to the right angle. In this case, it is

85.

The adjacent side to G is 36.

Therefore:

[tex]\displaystyle \cos (G)=\frac{36}{85}[/tex]

For your other question, remember that in a right triangle, cosine is the ratio of the adjacent side to the hypotenuse.

As you know, the hypotenuse is always the longest side in a right triangle.

Therefore, the ratio of the adjacent side to the hypotenuse will never be greater than 1.

Since 85/77 is greater than 1, it is undefined.

The same applies to sine as well.

Answer: [tex]1\dfrac{3}{8}\ \text{inch}[/tex]

Step-by-step explanation:

Given

Rainfall in September is [tex]\frac{7}{8}[/tex] inch

Rainfall in October is [tex]2\frac{1}{4}[/tex] inch

Convert mixed fraction into fraction

[tex]\Rightarrow 2\dfrac{1}{4}=\dfrac{9}{4}\ \text{inch}[/tex]

Difference between the two gives that how much more rain fall in October compared to September

[tex]\Rightarrow \dfrac{9}{4}-\dfrac{7}{8}\\\\\Rightarrow \dfrac{18-7}{8}\\\\\Rightarrow \dfrac{11}{8}\ \text{inch or}\\\\\Rightarrow 1\dfrac{3}{8}\ \text{inch}[/tex]

Step-by-step explanation:

1. 5+2+3=5+(2+3) 2. 9a is equivalent to 11a-2a 3. 7a + 04 - 2a is equivalent to 7a + -2a + 4 4. 8a-(8a-8) is equivalent or = to 8.

Hello! answer: 30

Step-by-step explanation:

13 × 13 = 169

5 × 5 = 25

169 - 25 = 144

12 × 12 = 144 therefore 12 is the missing leg

so we will use this to find the area so...

12 × 5 = 60 60 ÷ 2 = 30 therefore the answer is 30 hope that helps!

Answer:

37

Step-by-step explanation:

The range is the largest number minus the smallest number

99 is the largest number

62 is the smallest number

99-62

37

The range is the difference between the largest number and the smallest number.

Largest number is 99

Smallest number is 62

Range = 99-62 = 37

The answer is C) 37

Answer:

c. 10.8 cm

Step-by-step explanation:

s=√10²+4²=√116=10.8

x = time goal

16% = .16

.16 x = 32

x = 32/.16 = ___________ minutes

Jesse' weekly reading time is an illustration of ratio and proportion.

Jesse' weekly reading time is 200 minutes

Represent the reading time with x.

16% of his weekly reading time is given as 32 minutes

This is represented using the following equation

[tex]16 \% \times x = 32[/tex]

Express 16% as decimal

[tex]0.16\times x = 32[/tex]

Divide both sides by 0.16

[tex]x = 32/0.16[/tex]

[tex]x = 200[/tex]

Hence, Jesse' weekly reading time is 200 minutes

Answer:

96.29  mm^3

Step-by-step explanation:

Cylinder

V = pi r^2 h

V = 3.14 ( 2)^2 ( 5)

V = 3.14 *4*5

V =62.8 mm^3

Cone

V = 1/3 pi r^2 h

V = 1/3 (3.14) 2^2 ( 4)

V =1/3 (3.14) 4*4

V =16.746666666 mm^3

There are 2 cones so multiply by 2

Both cones = 33.493333333333 mm ^3

Add the cones and the cylinder together

62.8+33.493333333 =96.293333333
