Answer:

  x = 22°

Step-by-step explanation:

The interior angles in a triangle total 180°.

  x + a + 90° = 180°

When we subtract 90° from both sides of this equation, we find ...

  x + a = 90° . . . . . . . . the acute angles are complementary.

  x = 90° -a = 90° -68°

  x = 22°

Laura has 3.85 pounds of bananas. She goes to the store to buy 2.75 more pounds of bananas to make banana bread. Each loaf requires 0.30 pounds of bananas. How many loaves of bread can she make?​

Answers

Answer:

22

Step-by-step explanation:

3.85+2.75= 6.6

6.6÷0.30= 22

Answer:

The answer is 22 loaves of bread.

Step-by-step explanation:

You add 3.85 pounds + 2.75 pounds to get the total number of pounds she bought, which is 6.6 pounds of bananas.

Then you divide your total answer of 6.6 pounds by 0.30 pounds for each loaf, to get 22 loaves of bread.

Witch linear relation below has the largest slope? What is the slope?

Answers

Answer:

the graph has the largest slope. the slope is 5/2

Step-by-step explanation:

the slope of y=2x+4 is 2.

to get the slope of the table, see how much x increases and how much y increases. in this case, as x increases by 1, y also increases by 1, so the slope is 1.

to get the slope of the graph, find two or three points with whole numbers as both the x and y values. we can use (0, 2) and (2, 7). we can either make another table to see how the x and y values increase or look at the line and see how the line rises and runs. in this case, as x increases by 2, y increases by 5. the y value shows rise and the x value shows run, so we can write the slope as 5/2. we can see how the line rises by 5 and goes 2 units to the right. this gets the same slope as before.

1<2<5/2, so the graph has the largest slope.

The number of students at Yellowstone High School has been increasing by 4% each year. There are
currently 4,256 students. How many students will there be in 8 years?

Answers

Answer:

5,617.92

Step-by-step explanation:

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year.

Solving our equation:

A = 4256(1 + (0.04 × 8)) = 5617.92

A = $5,617.92

The total amount accrued, principal plus interest, from simple interest on a principal of $4,256.00 at a rate of 4% per year for 8 years is $5,617.92.

Answer:

¹/₄ hr or 0.25 hrs

⁷/₆ hr or 70 mins

He will make it in time (justification below)

4.

a. False

b. True

c. False

Step-by-step explanation:

The questions are all in relation to the equation:

speed (km/hr) = distance (km)/time (hr)

It may be worth learning about how formula triangles work because I think you would find them helpful, there are videos online on this

The first question is asking about times;

Rearranging the equation/formula above, time = distance/speed;

So, we just plug in the information for each distance travelled;

The first 30 km is covered at 120 km/hr;

So, the time taken will be:

t = ³⁰/₁₂₀

This simplifies to:

t = ¹/₄ = 0.25

So, it will take ¹/₄ hr or 0.25 hrs to cover 30 km at 120 km/hr;

¹/₄ hr is the same as 15 mins

The next 56 km is covered at 48 km/hr;

So:

t = ⁵⁶/₄₈

This simplifies to:

t = ⁷/₆

So, it will take ⁷/₆ hr or 70 mins

The second question requires us to know the time taken to cover 16 km at 100 km/hr;

t = ¹⁶/₁₀₀

This simplifies to:

t = ⁴/₂₅ = 0.16

So, ⁴/₂₅ hr or 9.6 mins

If he has 15 mins to make it to school and we've just calculated it will taken 9.6 mins, then he will make it in time

4.

a.

False

Jason runs 5 km in 30 mins, which means he could run 10 km in 60 mins;

Donna runs 9 km in 60 mins, so Jason runs at a faster speed since he would cover 10 km in 60 mins

b.

True

Rachel covers 10 km in 10 mins;

Speed will be:

10/10 = 1

So, her speed is 1 km/min

An hour is 60 mins so, her speed in km/hr will be:

60 × 1 = 60

60 km/hr

This is greater than the limit 50 km/hr

c.

False

The 2 runners run the same track, this means they run the same distance;

If James takes longer, then this is because he is running slower or, in other words, Paula is running faster
