Based on these calculations of driving 70 miles per hour for 4 hours, you must multiply 70 by 4.
70 x 4 = 280
For four hours of driving, the family drove 280 miles.

What are the solutions of x2 - 2x +5 = 0
Answer:
x = -3 or x = -5
Step-by-step explanation:
x (x -2 ) = -5
x = -5 or x = -5+2
x = -3
5 (6 - x) - 3 = 5 + 4 (x + 3)
Answer:
X=0
Step-by-step explanation:
5(6-X)-3=5+4(X+3)

what is the measure of angle A
Answer:
a = 53
Step-by-step explanation:
Start with d
The ends of d + 53 are diameter ends. That means that d + 53 is a right angle
d + 53 = 90
d = 90 - 53
d = 37
Next, find b. The end points of b are the same end points as for 53 degrees. B is the central angle of 53 which means b = 2 * 53
b = 106
c is the supplement of b
c + b = 180
b = 106
c + 106 = 180
c = 180 - 106
c = 74
The triangle containing a and c is isosceles because 2 of the 3 angles are opposite radii. The lowest angle is also a because it is opposite one of the radii.
a + a + 74 = 180
2a = 180 - 74
2a = 106
a = 106/2
a = 53
Hard to believe, but there it is.
find m<DCV and m<VBD
9514 1404 393
Answer:
m∠DCV = 50°m∠VBD = 50°Step-by-step explanation:
Arc DV is 100°, so any inscribed angle that intercepts that arc will have a measure that is half of 100°, or 50°.
Inscribed angles DCV and VBD both intercept arc DV, so both are 50°.

Jessica is traveling at a speed of 60 miles per hour in her truck. After 4 hours, how far will she have traveled?
Answer:
240 miles
Step-by-step explanation:
60*4=240
Answer: 240
Step-by-step explanation: If she is traveling 60 miles per hour you can multiply it by 4, which is 240.
A coin is tossed. If it shows heads, a marble is drawn from Box 1, which contains one white and two black marbles. If it lands tails, a marble is drawn from Box 2, which contains two white and two black marbles. Find P(black|coin fell tails).
Answer:
P(black|coin fell tails) = ¼
Step-by-step explanation:
Since a coin has a head and a tail, then probability of landing tail is;
P(tail) = ½
Now, if it falls tails, a marble is drawn from Box 2, which contains two white and two black marbles.
Thus, probability of getting a black marble is; 2/4 = ½
Thus;
P(black|coin fell tails) = ½ × ½ = ¼

Please help me solve this short problem I’m really struggling
Answer:
Step-by-step explanation:
In the standard form of a quadratic,
[tex]h(x)=-x^2+v_0x+h_0[/tex],
that last term, the h0, is the initial height off the ground that the object is. That means that for the first question, the irrigation system is initially 9.5 feet off the ground.
In order to answer the next question, we need to find the vertex of the parabola, because this is where the max height will occur and at how many feet away from the system. The max height is the k of the vertex and the horizontal distance away is the h of the vertex: (h, k). Thankfully, we have simple formulas to find those:
[tex]h=-\frac{b}{2a}[/tex] and [tex]k=c-\frac{b^2}{4a}[/tex] where a, b, and c come from the coefficients in the equation. For us, a = -1, b = 10, and c = 9.5. Finding h first:
[tex]h=-\frac{10}{2(-1)}=\frac{-10}{-2}=5[/tex]
and now k:
[tex]k=9.5-(\frac{10^2}{4(-1)})=9.5-(\frac{100}{-4} )=9.5-(-25)=9.5+25=34.5[/tex]
Summing it up, the vertex is at (5, 34.5), The interpretation of that is that "The spray reaches a max height of 34.5 feet at a horizontal distance of 5 feet away from the sprinkler head."
Next we are asked how far away from the sprinkler head the water hits the ground. To do this we factor the expression to find the zeros. The zeros tell us where the water will hit the ground after it reaches its max height and then falls back down to earth.
I used my calculator to factor this for me to get that the water will hit the ground 10.87 feet away from the sprinkler head.

Step-by-step explanation:
a rectangle has two pairs of equally long sides and each of the 4 angles between the sides is 90 degrees.
given that ABCDEF is a regular hexagon, it means that all its sides are equally long, and therefore also all internal angles are the same size.
that means for ACDF that the sides DC and FA are equally long.
DEF and ABC are congruent triangles, as the sides DE = BC, EF = AB, and the angle E is congruent to angle B.
based on the SAS criteria this confirms that DF is congruent to AC.
the angles ACB, CAB, EDF and EFD have to be all the same, and therefore also the angles FDC, DCA, CAF and DFA.
so, all 4 angles of the parallelogram ACDF are the same, and the sum of all these angles has to be 360 degrees, we have
360 = 4×angle
angle = 90 degree.
so, all angles are 90 degrees and we have two pairs of equally long sides : this process that ACDF us a rectangle
an umbrella is made by stitching 10 triangular pieces of cloth of two different colours where each pieces measuring 48cm,48cm,and 30cm. find cost of required to make umbrella at rate of 5paisa per square cm
Answer:
Step-by-step explanation:
first we need to calculate the area of isosceles triangle having sides 48cm, 48cm and 30cm
a = 48
b= 30
Area of isosceles triangle using only sides = ½[√(a^2 − b^2 /4) × b]
= 1/2*30√( 48² - 1/4×30²)
=1/2*30√ (2304 -225)
=684sq cm
cost required to make umbrella= 10*684*5
= 34200

Edwina and georgia had the same number of bottles.Edwina and georgia had a mix of big bottles and small bottles.Edwina had 5 small bottles while georgi had 16 big bottles.Each small bottles had a a capacity of 400 ml.Each big bottles had a capacity of 600 ml.The total capacity of edwina's bottles was 800 ml more than the total capacity of georgia's bottles
Answer:
20 big bottles
14000 ml
Step-by-step explanation:
Let :
Small bottles = x ; big bottles = y
Capacity of small bottle = 400ml
Capacity of big bottle = 600 ml
Edwina :
Number of small bottles = 5
Georgi :
Number of big bottles = 16
Since Numbe of bottles are siad to be the same :
5 + y = 16 + x
y - x = 16 - 5
y - x = 11
y = 11 + x - - - (1)
Total capacity of Edwina's bottle is 800 ml more Than Georgi's total :
Edwina :
5(400) + 600y
Georgi :
400x + 16(600)
2000 + 600y = 800 + 400x + 9600
2000 + 600y = 10400 + 400x
600y - 400x = 10400 - 2000
600y - 400x = 8400 - - - (2)
Substitute y = 11+x for y in (2)
600(11+x) - 400x = 8400
6600 + 600x - 400x = 8400
200x = 8400 - 6600
200x = 1800
x = 1800 / 200
x = 9
Number of big bottles Edwina has :
y = 11 + x
y = 11 + 9
y = 20
Total capacity of Edwina's bottles :
5(400) + 600y
2000 + 600(20) = 2000 + 12000 = 14000 ml
