Math question below
Answer : The surface area of triangular prism is 1080 in².
Step-by-step explanation :
Formula used to calculate the surface area of triangular prism is:
Surface area of triangular prism = (2 × Area of triangle) + Area of all rectangle
Area of triangle = [tex]\frac{1}{2}\times base\times height[/tex]
Area of rectangle = length × breadth
In the given triangular prism, there are 2 triangles and 3 different rectangles.
Surface area of triangular prism = [tex](2\times \frac{1}{2}\times base\times height)[/tex] + Area of rectangle ABCF + Area of rectangle ABDE + Area of rectangle CDEF
Surface area of triangular prism = [tex](2\times \frac{1}{2}\times 10\times 24)+(24\times 14)+(26\times 14)+(14\times 10)[/tex]
Surface area of triangular prism = 1080 in²
Therefore, the surface area of triangular prism is 1080 in².

A=bh=7*5=35
base= 7
height= 5
the formula is bh so you just multiply them and that's the area
Answer:
35 Sq. Units
Step-by-step explanation:
The Intuition for why the area of a parallelogram is A=bh (area = base x height)
The formula for the area of a parallelogram is base times height, just like the formula for the area of a rectangle.

A ladybug and ant move at constant speeds. The diagrams with tick marks show their positions at different times. Each tick mark represents 1 centimeter.
In your textbook pg. 111, scale the vertical and horizontal axes by labeling each grid line with a number. You will need to use the time and distance information in the tick-mark diagrams.
Which line shows the ladybugs movement? The ant?
Unit rate for the Ladybug? The ant?
How long does it take for the ladybug to travel 12 cm? The ant?
Answer:
From the graph we can say that ant is moving faster than the ladybug
Slope of the ant's movement will be steeper than the ladybug
Hence, line "v" denotes the speed of ant and line "u" denotes the speed of ladybug.Unit rate/slope of the graph is (distance traveled/elapsed time)
Unit rate of ant is 3/2 cm/sec and that of ladybug is 1 cm/sec.Ant takes (12×2/3) = 8 sec and ladybug takes (12×1) = 12 sec to travel 12 cm.Remember ant will take less time to travel a certain distance than ladybug.

What is the value of x
Group of answer choices
60 degrees
30 degrees
15 degrees
45 degrees
Answer:
x = 15 degrees
Step-by-step explanation:
This is a right angle, since we know that a right angle contains 90 degrees, we can form an equation.
[tex]30+4x=90[/tex]
Now, we solve for x.
[tex]-30+30+ 4x = -30+90[/tex]
[tex]4x=60[/tex]
[tex]\frac{4x}{4}=\frac{90}{4}[/tex]
[tex]x=15[/tex]
What times what equals 6 but adds to -1
Answer: Nothing
Step-by-step explanation: There aren't any numbers that multiply to equal 6 but add to be -1.
There aren't any numbers that multiply to equal 6 but add to be -1 but we can say -6 and positive 1.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.A mathematical equation is a statement with two equal sides and an equal sign in between. example, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
For that , we need to try solving it first using the method of substitution in which we express one variable in other variable's form and then it can substitute this value in other equation to get linear equation in one variable.
We need to find the number that equals 6 but adds to -1.
We can see that there aren't any numbers that multiply to equal 6 but add to be -1.
So, we conclude that number could be -6 and positive 1.

6/9 of 27 students in a class play soccer some of the students play offense and the rest play defense the ratio of the students playing offense to the total number of students playing soccer is 1 to3 how many students play defense
12 students play defense. 1st step. 6/9 of 27 is 18. 2nd. the ratio of the students playing offense to the total number of students playing soccer is 1 to 3 which means the total amount of students is '3', in the ratio it's 3 because it's simplified (i like to think of it as 'groups'). since we know that there are a total of 18 students and there's 3 total 'groups' we divide 18 into 3 which is 6. so there's 6 students in each group. we subtract 6 (1 group) from 18 ( the total number of students) which is 12, so there are 12 students playing defense. if you wrote the ratio again without simplifying it would be 6:18

-5(3-x)+4=5x-11
Answer:
Let's solve your equation step-by-step.
−5(3−x)+4=5x−11
Step 1: Simplify both sides of the equation.
−5(3−x)+4=5x−11
(−5)(3)+(−5)(−x)+4=5x+−11(Distribute)
−15+5x+4=5x+−11
(5x)+(−15+4)=5x−11(Combine Like Terms)
5x+−11=5x−11
5x−11=5x−11
Step 2: Subtract 5x from both sides.
5x−11−5x=5x−11−5x
−11=−11
Step 3: Add 11 to both sides.
−11+11=−11+11

Hilary has 48 building blocks in the red bucket. That is 6 times as many blocks in the green bucket. How many building blocks are in the green bucket?
Answer: 8
Step-by-step explanation:
From the question, we are informed that Hilary has 48 building blocks in the red bucket which is 6 times as many blocks in the green bucket.
Let the number of building blocks that are in the green bucket be represented by x.
Based on the scenario given in the question, this will be:
6 × x = 48.
6x = 48
x = 48/6.
x = 8
This means that there are 8 green building blocks

The population standard deviation for the height of college basketball players is 2.9 inches. If we want to estimate a 99% confidence interval for the population mean height of these players with a 0.45 margin of error, how many randomly selected players must be surveyed
Answer:
276
Step-by-step explanation:
Given :
Standard deviation (σ) = 2.9 inches
Error margin (E) = 0.45
Confidence interval = 99%
Using the relation to obtain the sample size (n)
n = [(Zcrit * σ) / E]²
Zcritical at 99% confidence interval = 2.576
n = [(2.576 * 2.9) / 0.45]²
n = [7.4704 / 0.45]²
n = 16.600888^2
n = 275.58951
n = 276 samples
Sample size
Find x & y so that quadrilateral is a parallelogram. (Look at image)
Answer:
x = - 6 y = 13
Step-by-step explanation:
we know when the diagonals bisect it divides into two equal parts so
-4x - 2 = -3x + 4
-4x + 3x = 4 + 2
- x = 6
x = - 6
Now
2y + 8 = 3y - 5
3y - 2y = 8 + 5
y = 13
