Answers

Answer:

Step-by-step explanation:

Since we have points (-1,5) and (3,4) we can find the slope m of y=mx+b

m=(y2-y1)/(x2-d1)=(5-4)/(-1-3)=1/-4=-1/4 so we have

y=-x/4+b, using point (3,4) we can solve for the y intercept, b.

4=-3/4+b, b=19/4, so the line is

y=(-x+19)/4

Amrita is 8 years elder to her brother Aman. If the ratio of their ages is 7 : 3, find their present ages?​

Answers

Answer:

Amrita = 14 years old

Aman = 6 years old

Step-by-step explanation:

Find out the difference of the units.

7 - 3 = 4

Amrita is 4 units/8 years older than Aman.

4 units = 8

1 unit = 8 ÷ 4 = 2

Amrita is 7 units and her brother is 3 units.

Amrita = 7 units x 2 = 14

Aman = 3 units x 2 = 6

John lays tile for a living. While trying to create the perfect design for his client, he then drew this pattern containing two right angles and an isosceles triangle.

For the triangles to fit together perfectly, John must determine the measure of angles 1, 2, and 3.

Answers

Answer:

Angle 1= 58

Angle 2= 64

Angle 3= 58

Step-by-step explanation:

The two smaller triangles are each right triangles and every triangle equals 180 so add 32 degrees and 90 degrees ( 90+32=122) and subtract that from 180 and you get angles 1 and 3 from your isosceles triangle

then you add both angles 1 and 3 from your isosceles triangle which are 58 degrees each (58+58=116) and subtract that from 180 (180-116=64) and you get angle 2

Answer:

angle 1 = 32

angle 2 = 116

angle 3 = 32

S. At Food Lion, 28 of every 35 jars of peanut butter on the shelves are creamy peanut butter. What percent of the jars of peanut butter are not creamy?​

Answers

Answer:

7/35 or 20% of the jars are not creamy

Answer:

20%

Step-by-step explanation:

To find the percent of NOT creamy:

35(total peanut butter) - 28(creamy) = 7

Question now is: 7 is what % of 35?

Formula = a(part) = p(percent)*w(whole)

p = a/w

7/35 = 0.2

0.2 is a decimal so multiply by 100 to get 20%

The answer should be 20% so I hope this helps!

What is the area of the triangle?

units?

Answers

4?

Jsndisnisjalnsnsis

The area of the triangle whose base is 4 unit and height is 2 unit is 4 square units .

To calculate the area of a triangle, we multiply the base by the height and divide the result by 2 .

Base of triangle = 4 units

Height of triangle = 2 units

Area of triangle = ( Base of triangle * Height of triangle ) / 2

Area of triangle = ( 4 * 2 ) / 2

Area of triangle = 8 / 2

Area of triangle = 4 square units

Therefore, the area of the triangle is 4 square units .

What is 8 x 8 x 8 in exponential form

Answers

Answer:

10^3

Step-by-step explanation:

103 is read as “10 to the third power” or “10 cubed.” It means 10 • 10 • 10, or 1,000.

82 is read as “8 to the second power” or “8 squared.” It means 8 • 8, or 64.

54 is read as “5 to the fourth power.” It means 5 • 5 • 5 • 5, or 625.

b5 is read as “ b to the fifth power.” It means b • b • b • b • b. Its value will depend on the value of b.

The exponent applies only to the number that it is next to. So in the expression xy4, only the y is affected by the 4. xy4 means x • y • y • y • y.

If the exponential expression is negative, such as −34, it means –(3 •  3 • 3 • 3) or −81.

If −3 is to be the base, it must be written as (−3)4, which means −3 • −3 • −3 • −3, or 81.

Likewise, (−x)4 = (−x) • (−x) • (−x) • (−x)  = x4, while −x4 = –(x • x • x • x).

Residual = 8.8 - (1.1(5) + 3.4) = - 0.1
