Help me please

Answers

Answer:

220/x=100/5

(220/x)*x=(100/5)*x       - we multiply both sides of the equation by x

220=20*x       - we divide both sides of the equation by (20) to get x

220/20=x

An Italian restaurant buys 15 pounds of onions every 2 weeks. how many bags of onions will the restaurant buy in 7 weeks?

Answers

Since it is 7 weeks and they order 15 pounds every two weeks they will order 3 times. 15 times 3 is 45. Your answer is 3 bags
2 goes into the 7 weeks 3 times with a remainder of a week until they buy another 15 pounds of onions. So 15 x 3 = 45 pounds. They’ll have 45 pounds of onions in 7 weeks as on the 8th week they’ll buy another 15 pounds but the question only wants to know by the 7th week.

many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could
you use to find n?

Answers

Answer:

62 coins are not nickels. you could just add the pennies, dimes, & quarters. those totals are given. So

29+16+17= 62

It is given that two lines are parallel, and hence the corresponding angles are congruent, by corresponding angles postulate. It is also given that the triangles in the photo share an angle, by the reflexive property, the shared angle is congruent. Hence one can use angle-angle to determine that the two triangles in the picture are similar.

Using this, one can set up a proportion with the sides. The ratios of any two corresponding sides are the same as any other two corresponding sides in the triangle, respectively, this is due to the corresponding parts of similar triangles theorem.

A set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set find P(X< 73)

Answers

Answer: .69

Step-by-step explanation:

Answer on khan

We can write the value in the range P(64 < {x} < 76) as 0.68.

What is standard deviation?

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.

Given is that a set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set.

It is given that -

μ = 70

σ = 6

For the range of {x}, we can write -

(μ - σ) < {x} < (μ + σ)

64 < {x} < 76

We can write the range of {z} value as -

(64 - 70)/6 < {z} < (64 + 70)/6

- 1 < {z} < + 1

Now -

P(64 < {x} < 76) = P(x < 76) - P(x < 64) = 0.84 - 0.15 = 0.68

Therefore, we can write the value in the range P(64 < {x} < 76) as 0.68.

∠A and \angle B∠B are complementary angles. If m\angle A=(2x-10)^{\circ}∠A=(2x−10) ∘ and m\angle B=(x-2)^{\circ}∠B=(x−2) ∘ , then find the measure of \angle A∠A.

Answers

Answer:

118°

Step-by-step explanation:

Two angles are called complementary when their measures add to 90 degrees.

From the question,

Angle A=(2x-10)°

Angle B=(x-2)°

Both Angles are complementary.

Therefore

Step 1

(2x - 10)° + (x - 2)° = 180°

2x + x - 10 - 2 = 180°

3x - 12 = 180°

3x = 180° + 12

3x = 192°

x = 192/3

x = 64°

Step 2

We are to solve for Angle A

(2x-10)°

Angle A = 2(64 ) - 10

Angle A = 128 - 10

Angle A = 118°

The measure of Angle A = 118°
