What is the total surface area??Please help me I’m so confused i have a test tomorrow
Answer:
216 :)
Step-by-step explanation:
There are five sides in total. To find the total surface area we have to find the area of each side.
Let's start off easy with the rectangle at the base. The width and length are 7 and 6, which gives us an area of 42.
The rectangle with dimensions of 8 as the length and 7 as the width gives us an area of 56.
The rectangle with a length of 10 and a width of 7 gives us 70 as an area.
The two triangles are congruent, so all we have to do is find the area of one and multiply it by two. The formula for an area of a triangle is 1/2(bxh)-or the two legs multiplied by each other and then divided by 2. The length of one of the legs is 8, and the other is 6. That gives us 48, which we will then divide by 2 to give us a total area of 24. Now we have to multiply that by two because there are two triangle sides on this figure and they are congruent. That gives us a product of 48.
Now we add up all the areas of each side:
42 + 56 + 70 + 48 = 216

Step-by-step explanation:
Vertically Opposite Angles,
[tex]12x - 8 = 40 \\ 12x = 40 + 8 \\ 12x = 48 \\ x = 48 \div 12 \\ = 4[/tex]
Lauren woke up one morning and saw frost on the windows. It was -13°C outside. Later in the day, the frost melted. At 3 p.m. it was 4°C outside. Which expression represents the difference between the two temperatures?
Answer:
morning = -13°C
afternoon = 4°C
so,
x = (morning - afternoon)

Number of boys number of girls 11:9 there is 124 more boys than girls work out the number of students at the school
Answer:
1240
Step-by-step explanation:
Number of boys to a girl is
x:y= 11:9
9x= 11y
There are 124 more boys in the schooll than girls
x= 124+y
Substitute 124+y for x
9(124+y)= 11y
1116+9y= 11y
1116= 11y-9y
1116= 2y
y= 1116/2
y= 558
Number of girls is 558
The number of boys can be calculated as follows
= 558+124
= 682
Hence the total number of students is
= 682+558
= 1240
7 plus a number z is more than 5
Answer:
z > -2
Step-by-step explanation:
7 + z > 5
subtract 7 from each side of the equation:
z > -2
The inequality for the given phrase is z+7>5.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given phrase is "7 plus a number z is more than 5".
Here, 7 plus a number z is
7+z
The obtained sum is more than 5.
That, is z+7>5
Subtract 7 on both the sides of an inequality, we get
z+7-7>5-7
z>-2
Therefore, the inequality is z+7>5.

An art teacher makes a batch of paint by mixing cup paint with cup paint. If she mixes batches, how many cups of paint will she have? The teacher will make nothing cups of paint.
Answer: 19 ¹/₂ cups of purple paint
Step-by-step explanation:
First find out the quantity of purple pain that she has:
= 3/4 + 3/4
= 6/4 cups of paint.
If she mixes 13 batches, the cups of purple paint she will have will be the original number multiplied by 13
= 6/4 * 13
= 78/4
= 19 ¹/₂ cups of purple paint

I went to the grocery store and my subtotal was $78.00. There is a 4.5% sales tax.How much is my total grocery bill including tax
Answer:
81.51
Step-by-step explanation:
So first you will want to take the percentage of the $78.00.
What we do is multiply 78.00 by 0.045
which is 4.5%
You then get $3.51
Add that to the $78.00:
78.00 + 3.51
= $81.51

What is an equation of a circle whose center is (1,4) and diameter is 10?
Question options:

Which inequality represents the situation? The maximum weight, w, an elevator can lift is 2,200 pounds. w ≥ 2,200 w > 2,200 w ≤ 2,200 w < 2,200
Answer:
w ≤ 2200
Step-by-step explanation:
If a lift can lift a maximum weight of 2200pounds, this means that the lift can not life a weight greater than 2200pounds. For the expression needed, the inequality sign to use will be a less than or equal to sign( ≤ ).
Hence the requires inequality expression will be w ≤ 2200

In the accompanying diagram of rectangle ABCD, diagonal AC is drawn, DE = 8, DE 1 AC, and m2 DAC = 55. Find the area of rectangle ABCD to the nearest integer.
Answer:
sin (55) = DE / AD
AD = DE / sin (55)
AD = 8 / sin (55)
And
tan (55) = DC / AD
tan (55) = DC / [8 / sin (55) ]
DC = 8 tan (55) / sin (55)
AD * DC =
[8 /sin (55) ] [ 8 tan (55) / sin (55) ] = 136 units^2
