Answer:

The missing value is [tex]14[/tex].

Step-by-step explanation:

Divide the known denominator by its numerator.

[tex]4\div2=2[/tex]

Now multiply the quotient by the other numerator ([tex]7[/tex]).

[tex]2×7=14[/tex]

or

First, find the factor by which the numerators have been multiplied.

[tex]2x=7→x=3.5[/tex]

Now, do the same for the denominators.

[tex]4(3.5)=14[/tex]

Answer:

Distance B = 1275 kilometers.

Step-by-step explanation:

Let the two distances and time be A and B respectively.

Given the following data;

Distance A = 17 kilometers.

Time A = 8 minutes.

Distance B =?

Time B = 60 minutes.

First of all, we would find the constant speed;

Speed = distance/time

Substituting into the equation, we have;

Speed = 17/8

Speed = 2.125 km/m

Now, to find the distance B;

Distance B = speed * time

Distance B = 2.125 * 60

Distance B = 1275 km

Answer:

0.88 (I think this is how Mrs. Futch wants it to be written)

Step-by-step explanation:

h=-16t^2+14t

(Substitute h with 0)

0=-16t^2+14t

(Factor)

0=2t(-8t+7)

2t=0               -8t+7=0

t=0                  t=0.88

{0, 0.88}

Answer:

140 m^2

Step-by-step explanation:

area of triangle is (base X height)/2

so it would be (20 X 14)/2

which equals 140

Answer: True

Step-by-step explanation:

Cost = 15 + 3t

22.5 = 15 + 3(2.5)

22.5 = 15 + 7.5

22.5 = 22.5 <— true

Answer:

true

Step-by-step explanation:

2.50 x 3 = 7.50

15 + 7.50 = 22.50

22.50 = 22.50

Answer:

slope:(-0.5) y-intercept:0 equation:(-0.5x)

Step-by-step explanation:

To find slope, you use the formula y2-y1/x2-x1

For example, I used the first 2 sets of coordinates used in the table

(-2,1)&(-1,0.5)

First Part: 0.5-1= -0.5

Second part: -1-(-2)=1

Third Part: -0.5/1=(-0.5)

Y-intercept: In order to find the y-intercept, x needs to be 0.

Y-intercept=0

Equation:

The form for the equation should be, mx+b

B=Y-intercept

M=Slope

X=variable

The slope is -0.5 and you add the x after -0.5

Since the y-intercept is 0, it doesn't have a value so putting 0 at the end would be unnecessary. Slope:-0.5x

Answer:

It is times 4

Answer:

Step-by-step explanation:

Answer:

A boat traveled 19 kilometers east and 53 kilometers south, how far from its starting position is it?: √3170≈56.3 km.

A 25-foot ladder rest against a house at a point 24.1 feet above the ground. How far away from the house is the base of the ladder?: √44.19≈6.65 ft.

Step-by-step explanation:

For these questions, we will need to use the pythagorean theorem: a²+b²=c², where a and b are the legs of the right triangle and c is the hypotenuse.

A boat traveled 19 kilometers east and 53 kilometers south, how far from its starting position is it?

In this question, we are looking for the hypotenuse.

19 and 53 are the legs of the triangle, so we can plug it into the equation:

19²+53²=c²

361+2809=c²

3170=c²

√3170=c

56.30275304103699, or approximately 56.3 km.

A 25-foot ladder rest against a house at a point 24.1 feet above the ground. How far away from the house is the base of the ladder?​

25 is the hypotenuse since it is leaning sideways and is the longest side. 24.1 is one of the legs.

In this question, we are looking for one of the legs.

Let's plug it in: 24.1²+b²=25²

580.81+b²=625

Subtract 580.81 from both sides.

b²=44.19

b=√44.19

6.647555941848102, or approx. 6.65 ft.

Answer:

The image point of (-7, 1) after reflection across the y-axis is:

Step-by-step explanation:

When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.  

Thus,  

The rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

In our case, we are given the point (-7, 1)

Let say the point is A(-7, 1).

Thus, using the rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

A(-7, 1) → A'(-(-7), 1) → A'(7, 1)

Therefore, the image point of (-7, 1) after reflection across the y-axis is:
