4t = 40
10 + t = 14
70 - t = 30
multiple answers , 40, 10 , 4
Answer:
1. t=102. t=43. t=40Step-by-step explanation:
Isolate the term of t from one side of the equation.
1. 4t=40First, you have to divide by 4 from both sides.
4t/4=40/4
Solve.
Divide the numbers from left to right.
40/4=10
t=102. 10+t=14First, change sides.
t+10=14
Then, subtract by 10 from both sides.
t+10-10=14-10
Solve.
Subtract the numbers from left to right.
14-10=4
t=43. 70-t=30First, subtract by 70 from both sides.
70-t-70=30-70
Solve.
30-70=-40
Rewrite the problem down.
-t=-40
Divide by -1 from both sides.
-t/-1=-40/-1
Solve.
Divide the numbers from left to right.
-40/-1=40
t=40Therefore, the correct answer is t=10, t=4, and t=40.I hope this helps! Let me know if you have any questions.
Answer:
4t =40 t= 10 4x10=40
10 + t = 14 t=4 10 + 4 = 14
70 - t =30 t= 40 70 - 40 = 30
Hope this helps!

Linear is basically a straight line. It can be increasing or decreasing.
Decreasing is when on the graph, when x increases, y decreases.
On the graph, there are two parts that are decreasing. Between -2 and 0, and Between 2 and 4. Let's look at these two.
- For between -2 and 0, the line is not straight. Therefore, it is decreasing and nonlinear. We can check if this is the right answer.
- For between 2 and 4, the line is decreasing. However, the line is straight, which means it is decreasing but linear.
Your final answer is B.

A rectangular prism has a base of 15 ft2 and a height of 9 ft. What is the volume of the rectangular prism?
Answer:
135 ft^3
Step-by-step explanation:
Volume of a rectangular prism is basically just width x height x depth. So the area of the base multiplied by the height. 15 x 9 = 135
Answer: 135 ft³
Step-by-step explanation:
Volume, when dealing with a rectangular prism, is L * W * H
-> L * W can simplify to the base, as it does in the problem given to us.
V = (L * W) * H
V = B * H
V = 15 * 9
V = 135 ft³
The rectangular prism has a volume of 135 ft³.

50 PTS!!A right triangle has a leg measuring 16in. And 28in.
What is the length of the hypotenuse?
Round your answer to the nearest tenth.
1)23.0 in.
2)32.2 in.
3)44.0 in.
4)1040.0 in
Answer:
2) 32.2 in (nearest tenth)
Step-by-step explanation:
Pythagoras’ Theorem
[tex]\sf a^2+b^2=c^2[/tex]
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Given:
a = 16 inb = 28 inc = hypotenuseSubstituting these values into the formula and solving for c:
[tex]\implies \sf 16^2+28^2=c^2[/tex]
[tex]\implies \sf 256+784=c^2[/tex]
[tex]\implies \sf c^2=1040[/tex]
[tex]\implies \sf c=\pm\sqrt{1040}[/tex]
[tex]\implies \sf c=\pm 32.2\:in\:(nearest\:tenth)[/tex]
As distance is positive, c = 32.2 in (nearest tenth)
Step-by-step explanation :
Here, A right angled triangle is given with the measure of two sides and we are to find the measure of the third side.
We'll find the measure of third side with the help of the Pythagorean theorem,
[tex]\\ {\longrightarrow \pmb{\sf {\qquad (Hypotenuse {)}^{2}= (Base) {}^{2} + (Perpendicular {)}^{2} }}} \\ \\ [/tex]
Here,
The base (BC) is 16 inThe perpendicular (AB) is 28 inThe hypotenuse is AC.[tex] \: [/tex]
So, substituting the values in the formula we get :
[tex]\\ {\longrightarrow \pmb{\sf {\qquad (AC {)}^{2}= (16) {}^{2} + (28 {)}^{2} }}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad (AC {)}^{2}=256 + 784 }}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad (AC {)}^{2}=1040 }}} \\ \\[/tex]
[tex]{\longrightarrow \pmb{\sf {\qquad AC = \sqrt{1040} }}} \\ \\[/tex]

Answer:
[tex]f^{-1}[/tex] (59) = 20
Step-by-step explanation:
[tex]f^{-1}[/tex] (x) is the inverse of f(x)
to find the inverse function, let f(x) = y and rearrange to make x the subject.
y = 3x - 1 ( add 1 to both sides )
y + 1 = 3x ( divide both sides by 3 )
[tex]\frac{y+1}{3}[/tex] = x
change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then
[tex]f^{-1}[/tex] (x) = [tex]\frac{x+1}{3}[/tex] , then
[tex]f^{-1}[/tex] (59) = [tex]\frac{59+1}{3}[/tex] = [tex]\frac{60}{3}[/tex] = 20
Solve for x. The triangles in each pair are similar.
Step-by-step explanation:
similar triangles means that all angles in one triangle are exactly the same as the angles in the other triangle.
and the lengths of all sides of one triangle have the same scaling factor with the lengths of the sides of the other triangle.
so, when we compare the "features" of the triangles, we see that C corresponds to S, B to R and D to T.
so, DC (50) corresponds to TS (70).
and that means that CB (60) corresponds to SR (11x - 4).
the scaling factor from BCD to RST is 70/50 = 7/5.
that means DC × 7/5 = TS.
and CB × 7/5 = SR :
60 × 7/5 = 11x - 4
12 × 7 = 11x - 4
84 = 11x - 4
88 = 11x

Converting using the scale 1 in = 15 yd, we get that the dimensions of the park are 22.5 inches by 37.5 inches.
So, converting this back using 1 inch to 10 yards, we get dimensions of 2.25 inches by 3.75 inches.
