We have to double 5 and add 1 to get the same result.
5 + 5 + 1 = 11
We can also double 6 and subtract 1 to get the same result.
6 + 6 - 1 = 11
Hope this will helpful.
Answer:
They can use counters or their fingers, but they can also use doubles facts. If they know 5 + 5 = 10, they know that the sum of 5 + 6 will be one more. Thus, 5 + 6 = 11. Practice solving other doubles-plus-one facts together, such as 3 + 4, 7 + 8, and 9 + 8.
Together, teammates Pedro and Ricky got 2682 base hits last season. Pedro had 280 more hits than
Ricky. How many hits did each player have?
Answer:
Ricky had 1201 hits and
Pedro hade 1481 hits
Step-by-step explanation:
Let Ricky be 'y'.
Since, Pedro hit 280 mroe than Ricky.
Pedro is 'y+ 280'
Thus,
y + y+ 280 = 2682
2y = 2402
y = 1201
Ricky had 1201 hits and
Pedro hade 1201 + 280 = 1481 hits
Answer:
See below ~
Step-by-step explanation:
Let :
Hits by Ricky = xHits by Pedro = x + 280Solving :
Mentions the sum is 2682x + x + 280 = 26822x = 2402x = 1201Solution :
Hits by Ricky = x = 1201 hitsHits by Pedro = x + 280 = 1201 + 280 = 1481 hitsA linear function has a y-intercept of -9 and a slope of 4/3 . What is the equation of the line

What is angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
The height g(t) above the center after t minutes is given by
g(t) = 25cos(r(t))
g(t) = 25cos(2t) feet+30

Answer:
D 36.6
Step-by-step explanation:
Here, there is a triangle inscribed inside of a semicircle where the triangle is unshaded and the remained of the semicircle is shaded and we want to find the area of that shaded untouched area of the semicircle.
To do so we must find the area of the two shapes individually and then subtract the area of the triangle from the area of the semi circle as the triangle is what is uncovering the semicircle.
Finding the area of the semicircle
Area of a semicircle = (πr²)/2 where r = radius
Here we are given the diameter of the semicircle which is 13cm. We can easily convert the diameter to radius by dividing it by 2 as the radius is equal to half the diameter
Radius = 1/2 diameter , so radius = 13 / 2 = 6.5cm
We have A = πr²/2
==> plug in radius or r = 6.5
A = π(6.5)²/2
==> simplify exponent
A = π(42.25)/2
==> multiply π and 42.25 ( note that π = 3.14 approximately
A = 132.665/2
==> divide 132.665 by 2
A = 66.366
So the area of the semicircle is 66.366cm²
Finding the area of the triangle
The area of a triangle can be calculated by dividing the product of the base length and height ( formula = bh / 2 where b = base length and h = height )
Here the base length appears to be 5cm and the height appears to be 12cm so b = 5 and h = 12
So we have A = bh/2
==> plug in b = 5 and h = 12
A = (12)(5)/2
==> multiply 12 and 5
A = 60 / 2
==> divide 60 by 2
A = 30
So the area of the triangle is 30cm²
Subtracting the area of the triangle from the area of the semicircle
Finally to find the area of the shaded region we subtract the area of the triangle from the area of the semicircle
We have area of triangle = 30cm² and area of semicircle = 66.366
So area of shaded region = 66.366 - 30 = 36.366

what is the approximate value of x in the exponential 4^x=14?
We know 4² = 16 , 4¹= 4
In this case we have :-
[tex] {4}^{x} = 14[/tex]
and we have to find the value of x
14 is less than 16 so x will be less than 2
14 is greater than 4 so x will be greater than 1
we can find the value of
[tex] {4}^{1.5} = {4}^{ \frac{3}{2} } \\ { (\sqrt{4}) }^{3} = {2}^{3} = 8[/tex]
so we can say 14 is much larger than 8 which means x will be much larger than 1.5
so according to above ideas we can say our answer is 2nd option which is 1.9037 is our answer
[tex]x \approx1.9037[/tex]
[tex]~~~~~~~4^x = 14 \\\\\implies \ln 4^x = \ln 14\\\\\implies x \ln 4 = \ln 14\\ \\\implies x = \dfrac{\ln 14}{ \ln 4}\\\\\implies x \approx 1.9037[/tex]
