Answer 1

Answer:

d1 = 192

d2 = 192

Step-by-step explanation:

step 1

From the imformation given, the distance is the same

so from the table

d1 = 64t

d2 = 48(7-t)

the distance is the same, it means

d1 = d2

therefore we can get the time(t) from here

64t = 48(7-t)

64t = 336 - 48t

collect like terms

64t+48t = 336

112t = 336

t = 336/112

t = 3

substitute t into d1 to get the distance

d1 = 64t

d1 = 64 × 3

d1 = 192

Note, d1 = d2

d2 = 192 too

Use substitution to solve the following system of equations.
x + 2y = 13
3x - 5y = 6

Answers

Answer:

{1} x + 2y = 13

{2} 3x - 5y = 6

x = 13 - 2y

substituting into {2}

3x -5y = 6

3( 13 - 2y) - 5y = 6

39 - 6y -5y = 6

-11y = 6 -39

y = -33 /-11

 ( minus and minus cuts in fraction, so the answer will come in positive)

y = 3

now , substituting into {1}

x + 2(3) = 13

x = 13 -6

x = 7

so,

the solution are:-

x = 7

y = 3

In a right triangle, the measures of the two smaller angles are (3x+6) and (2x - 1)º. Find the measure of the smallest
angle in the triangle.
A. 170
B. 33°
C. 570
D. 90°

Answers

Answer:

B is the answer

Step-by-step explanation:

Since there is already a 90 degree angle in the right triangle, the other two angles must add up to 90.

[tex]3x + 6 + 2x - 1 = 90[/tex]

[tex]5x + 5 = 90[/tex]

[tex]5x = 85[/tex]

[tex]x = 17[/tex]

Plug 17 into both to find the smaller angle

[tex]3(17) + 6 = 57[/tex]

[tex]2(17) - 1 = 33[/tex]

[tex]33 < 57[/tex]

So 33 is the answer or B

Answers

Answer:

5

Step-by-step explanation:

Vanilla ice cream = 3/5 x 25 = 15

Answers

Answer:

arc WVY = 250°

Step-by-step explanation:

The tangent- tangent angle YXW is half the difference of the intercepted arcs

[tex]\frac{1}{2}[/tex] ( WVY - WY) = 70

[tex]\frac{1}{2}[/tex] (10a - (4a + 10) ) = 70 ( multiply both sides by 2 )

10a - 4a - 10 = 140

6a - 10 = 140 ( add 10 to both sides )

6a = 150 ( divide both sides by 6 )

a = 25

Then

arc WVY = 10x = 10 × 25 = 250°

[tex]\huge\boxed{\text{B) 1}}[/tex]

Step-by-step explanation:

In order to find which expression is equivalent to [tex](8^5 \times 3^{-7})^0[/tex], we need to note the order of operations.

PEMDAS tells us that when solving an equation, we'd go in this order.

Parentheses

Exponents

Multiplication/Division

Addition/Subtraction

Using this, we'd start by evaluating what's inside the parentheses, [tex]8^5 \times 3^{-7}[/tex]. We'd then bring that value to the 0th power.

Wait... there's something special about bringing anything to the 0th power. Bringing anything to the 0th power makes the value 1.

It can be -5... it can be 1,000,000, any number possible, taken to the 0th power, will always be 1.

So no matter what the value inside the parentheses is, taking it to the 0th power will always make it 1.

Therefore, this expression is equivalent to 1.

Hope this helped!
