Evaluate 3(a+b) for a=− 1/2 and b=2 1/2 . Record the answer in the simplest way.
Answer: 3(1/2 + 2 1/2) = 3(1/2+5/2) = 3(6/2) = 3*3 = 9
Step-by-step explanation:
Step-by-step explanation:
[tex]3(a+b)[/tex]
Since we know that a equals -1/2 and b equals 2 1/2, then we can plug in the values into the equation.
[tex]3(-\frac{1}{2} +2 \frac{1}{2} )[/tex]
First, solve everything in the parentheses.
[tex]3(2)[/tex]
Now, multiply 3 by 2.
[tex]3*2=6[/tex]
So, your answer will be 6.
what is the surface area of this wedge
Answer:
84 ft
Step-by-step explanation:
triangle= 1/2bh
rectangle or square = bh
so 1/2(4)3=6
6 times 3= 18
1/2(4)3= 6
4 times 6 = 24
5 times 6 = 30
now you add them all up
6 + 18 + 6+ 24+ 30 =
The Surface area of this wedge is 84 square ft.
What is Surface Area?The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well.
For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area.
To find the Surface are we will find the area of each part individually.
We have two triangle and 3 rectangles.
So, area of Triangle
= 1/2 b h
= 1/2 x 4 x3
= 6 square ft
Area of rectangle
= l w
= 6 x 3
= 18 square ft
Area of 2 rectangle
= l w
= 4 x 6
= 24 square ft
and, area of 3rd rectangle
= 5 x 6
= 30 square ft
So, the Surface area of Figure is
= 6 + 18 + 6 + 24 + 30
= 84 square ft

Find the value of b rounded to the nearest tenth
Answer:
You can use the Law of Sines for this problem, but what makes it tough at first glance is that they put a step in before you can use it directly. That first step is to get m∠C. When solving a triangle, always get the third angle if you know the other two so that you can use the Law of Sines (or Law of Cosines) more directly.
The sum of the angles of any triangles is 180°. We know the measures of the two other angles. So we subtract them from 180° to find that third angle.
180° - 76° - 66° = 38°
Now we can use the proportion from the picture. Angle B measures 76°, side b is our unknown, Angle C measures 38°, and side c measures 3 units.
sin 76° sin 38°
----------- = -----------
b 3
Cross multiply to find b (the side). We carry out five places in these calculations to get more accuracy.
3 * sin 76° = b * sin 38°
b = 3 * sin 76° 3 * 0.56611 1.69832
--------------- = --------------- = ---------------- = 5.73044
sin 38° 0.29636 0.29636
To the nearest tenth, b - 5.7 units.

A. All terms are even because even + even = even.
B. All terms are even because odd + odd = even.
C. All terms are odd because odd + even = odd.
D. All terms are even because when you add two numbers together, the sums are always even.
Answer:
A.
Step-by-step explanation:
All terms are even. This means it either has to be A. or B. Since 24 is an even number, two even numbers are always added together. So A. is the correct answer.
Answer:
A.
any number even + even = even
10 + 14 = 24 and 24 is even
12+24=36 which is even
Odd + odd does = even but it doesn't represent the situation so it is wrong.

A 26 ft ladder leans against a wall. The bottom of the ladder is 10 ft from the wall. How tall is the top of the ladder on the wall?
Answer:
It is going to be 16 ft because
26 ft - 10 ft = 16 ft
can u mark me brainliest plz
Answer:
the top of the ladder is at 24 feet from the ground
Step-by-step explanation:
Use the Pythagorean theorem to solve for the unknown, since we notice that the ladder is the hypotenuse of a right angle triangle formed by the horizontal distance from the wall to the base of the ladder, and the height of the top of the ladder against the wall. We need to find one of the triangle's sides given its hypotenuse and the other side, so we use the formula:
[tex]side_2=\sqrt{hyp^2-side_1^2}\\ side_2=\sqrt{26^2-10^2} \\side_2=\sqrt{676-100} \\side_2=\sqrt{576} \\side_2=24\,\,ft[/tex]

The shape has an area of 60 square inches. Find the value of x.
Answer:
8 inches
Step-by-step explanation:
ROCK is a kite. The area of a kite is denoted by:
A = (1/2) * d1 * d2, where d1 and d2 are the diagonals
Here, the two diagonals are x and 15, and we know the area is 60, so plug these into the equation:
A = (1/2) * d1 * d2
A = (1/2) * 15 * x
60 = (1/2) * 15 * x
x = 120 / 15 = 8
Thus, x = 8 inches.

[tex]8 \: \: inch[/tex]

Jivesh is analyzing the flight of a few of his model rockets with various equations. In each equation, h is
the height of the rocket in centimeters, and the rocket was fired from the ground at time t = 0, where t is
measured in seconds.
Jivesh also has a more powerful Model B rocket. For this rocket, he uses the equation h =-81012+1,980t.
When is the height of the Model B rocket 1,210 centimeters? Round your answers to the nearest
hundredth.
After how t “” seconds, the rocket will have reached a height of 1,210 centimeters
Answer:
1.22 s
Step-by-step explanation:
h = -810t² + 1980t
This is the equation of a parabola.
We must solve the equation to find the maximum height (h).
The coefficient of x² is negative, so the parabola opens downward, and the vertex is a maximum.
One way to solve this problem is to convert the equation to the vertex form.
We do that by completing the square.
Calculation:
h = -810t² + 1980t
Divide both sides by -810 to make the coefficient of t² equal to 1.
(-1/810)h = t² - (22/9)t
Square half the coefficient of t
(-11/9)² = 121/81
Add and subtract it on the right-hand side
(-1/810)h = t² - (22/9)t + 121/81 - 121/81
Write the first three terms as the square of a binomial
(-1/810)h = (t - ¹¹/₉)² -121/81
Multiply both sides by -810
h = -810(t - ¹¹/₉)² + 1210
You have converted your equation to the vertex form of a parabola:
y = a(t - h)² + k = 0,
where (h, k) is the vertex.
h = ¹¹/₉ and k = 1210, so the vertex is at (¹¹/₉, 2100).
The maximum height of the rocket is 2100 cm.
After ¹¹/₉ s ≈ 1.22 s, the rocket will have reached a height of 1210 cm.
The graph below shows the rocket reaching 1210 cm at 1.22 s.

Answer:
2x + 3y = 46
3x + 5y = 74
Multiply 1st equation by 3 and 2nd equation by 2:
6x + 9y = 138
6x + 10y = 148
Subtract 2nd equation to 1st equation:
=> y = 148 - 138 = 10
=> 2x + 3*10 = 46
=> 2x = 16
=> x = 8
