Answer:
1) ten subtracted from the product of a number and -3 is 29
x*(-3) - 10 = 29-3x = 39x = -132) the difference between a number and nine , divided by 4 , is -7
x - 9/4 = -7x = 9/4 - 7x = -19/4A line crosses through the points (0,2) and (-10, -16). Which of the following is the slope of the line?
A. 9/5
B. 5/9
C. -9/5
D. 1/3
Answer:
A). 9/5
Step-by-step explanation:
To find the slope, plug the values of x and y into the slope formula.
y2 - y1 / x2 - x1
-16 - 2 / -10 - 0
9/5
what is the area of this figure?
Answer:
A = 147 m²Step-by-step explanation:
The area of this figure is a sum of areas of a rectangle 5 m × 21 m and a triangle with base of 21 m and hight of 4 m.
A = 5×21 + 0.5×21×4 = 105 + 42 = 147 m²
Select an equation that is equivalent to a^2-144b^2 a) (a-12b)^2 B) (a+12b)^2 C) (a-12b)(a+12b) C) a^2-24ab+144b^2
Answer:
C) (a-12b)(a+12b)
Step-by-step explanation:
a^2-144b^2 = (a-12b)(a+12b)
This is the formula that when two terms squared are written with a minus sign between them their factors are the product of the original numbers once with a plus sign and once with the minus sign.
This can be explained by multiplying them.
(a-12b)
*(a+12b)
a²- 12ab
+12ab - 144b²
a² +0 - 144b²
We see we get the same answer as applying the formula above.

The surface area of the solid is 176 in².
What is surface area?Surface area is the amount of space covering the outside of a three-dimensional shape.
Given that a solid figure made by joining two cuboids, we need to find the total surface area of the solid,
So, we will find the TSA of lower and upper cuboids and then minus the base area of the upper cuboid as it is a overlapping,
Also, the formula used for TSA of a cuboid = 2(LH + WH + LW)
L = length, W = width and H = height,
So,
TSA = 2(7·3 + 3·5 + 5·7) + 2(4·3 + 3·1 + 4·1) - 1·4
= 2(21 + 15 + 35) + 2(12 + 3 + 4) - 4
= 2 × 71 + 2 × 19 - 4
= 142 + 38 - 4
= 142 + 34
= 176 in²
Hence the surface area of the solid is 176 in².

What is the measure of ∡U in the figure shown? ∘
Answer:
∠ U = 70°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the circle , then
∠ U + 50° = 120° ( subtract 50° from both sides )
∠ U = 70°

A survey of 5,913 American adults concludes that 53% of them prefer Captain America to Ironman. Find the Margin of Error. Type your answer as a Percentage rounded to 1 decimal.
Answer:
1.3%
Step-by-step explanation:
Phat = 0.53
1 - phat = 1 - 0.53 = 0.47
Sample size, n = 5913
Assume the confidence level = 95%
Zcritical at 95% = 1.96
Margin of Error = Zcritical * √(phat(1 -phat)) / n
Margin of error :
1.96 * √((0.53 * 0.47) / 5913)
1.96 * 0.0064905
= 0.0127215
= 0.0127215 * 100%
= 1.272%
= 1.3%

A spinner and 4 cards are shown below:
A spinner with 5 equal sectors is shown in the figure. The colors Green, Blue, Purple, Yellow, and Red are marked on it. The arrow points at the purple color. Four cards are shown on the right side. The colors Red, Yellow, Blue, and Pink are marked on them.
Jane spins the spinner and selects a card without looking. What is the probability that the spinner stops at purple and a pink card is selected?
1 over 20
1 over 5
1 over 4
9 over 20
Answer: 1 over 20
Step-by-step explanation: If the spinner has 5 parts to it at purple is one of those parts then the spinner has a 1/5 chance of it landing there.
If there are 4 cards and 1 of them are pink then there is a 1/4 chance of picking pink(if done randomly)
So if we mutiply 1/4 and 1/5, we get 1/20
That is how I arrived at my answer of 1 over 20
Raymond used 36 cubes to build the first layer of a rectangular prism. The edge length of each cube was 1 inch. The finished prism had a total of 8 layers. What is the volume of Raymond's prism in cubic inches?
Answer:
[tex]Volume = 288in^3[/tex]
Step-by-step explanation:
Given
[tex]Base\ Cubes = 36[/tex]
[tex]Layers = 8[/tex]
Required
The volume of the prism
The number of base cubes represents the base area and the number of layers represents the height of the prism.
So, the volume is calculated as:
[tex]Volume = Base\ Cubes * Layers[/tex] i.e Base Area * Heights
[tex]Volume = 36 * 8[/tex]
[tex]Volume = 36in^2 * 8in[/tex]
[tex]Volume = 288in^3[/tex]

Decrease 117 kg in the ratio 10:13
Answer:
90kg
Step-by-step explanation:
it is so because, to decrease a number by a ratio you have to multiply with the smallest number and divide with the biggest one. For example 117 in the ratio 7:3. 117×3=351 which is divided by 7 and is equal to 50.14.
The value 117kg decreased in the ratio 10:13 will be 90kg
Ratios and proportionGiven the ratio 10:13. To reduce 117kg in this ratio, we will follow the steps:
Step 1: Multiply 117 by the smallest value
117 * 10 = 1170
Step 2: Divide the result by the largest value to have:
Value = 1170/13
Value = 90kg
Hence the value 117kg decreased in the ratio 10:13 will be 90kg
